NASA contract May Put Inflatable secretive Module on Space Station

NASA and Bigelow Aerospace have reached a contract that could cover the method for attaching a Bigelow-built inflatable space habitat to the International Space Station, a NASA spokes man said.

The $17.8 million agreement was signed in late December, NASA spokesman Trent Perrotto told Space News Monday. Perrotto declined to offer other conditions of the accord, except to speak that it centers on the Bigelow extended Aerospace Module. He said an official statement is in the works.

The contract signed in December follows a nonpaying NASA agreement Bigelow got in 2011, under which the North Las Vegas, Nev., company worked up a catalog of rules and protocols for totaling BEAM to the space station. Bigelow got that agreement, which did not call for any flight hardware, in response to a 2010 NASA Broad Agency Announcement seeking thoughts for support equipment and services meant to help the U.S. part of the International Space Station live up to its billing as a countrywide laboratory.

SpaceX and Orbital are below agreement for space station cargo deliveries through 2016. So far, only SpaceX has flown to the location. The company, which flies Dragon cargo capsules atop Falcon 9 rockets, finished its initial contracted run in October. Orbital, which is raising a cargo freighter called Cygnus for begin aboard its new Antares rocket, is now listed to start a demonstration cargo run in February from NASA’s Wallops Island Flight Facility in Virginia.

NASA Eyes Wild Plan to haul Asteroid close to the Moon

Capturing a near-Earth asteroid and dragging it into path around the moon could aid humanity put boots on Mars sometime, proponents of the design say.

NASA is allowing for a $2.6 billion asteroid-retrieval assignment that could transport a space rock to tall lunar orbit by 2025 or so, New Scientist reported last week. The plan could help jump-start manned examination of deep space, carving out a pathway to the Red Planet and maybe even more far-flung destinations, its developers keep.

"Experience gained via human expeditions to the little returned NEA would move straight to follow-on global expeditions beyond the Earth-moon system: to other near-Earth asteroids, Phobos and Deimos, Mars and potentially sometime to the main asteroid strap," the mission idea team, which is based at the Keck organization for Space Studies in California, wrote in a viability learn of the map last year.

Space organization officials verify that NASA is indeed looking at the Keck suggestion as a way to help extend humanity's footprint out into the solar system. But the appraisal is still in its early stages, with nothing determined yet.

Up-close test of a captured asteroid would also yield insights into the financial value of space rock capital and hut light on the top ways to deflect potentially unsafe asteroids away from Earth.

NASA could revolve space waste into radiation shields

NASA researchers are testing strips made of trash — including plastic water bottles; clothing scraps, canal tape and foil drink pouches — in a try to twist astronauts' garbage into a space mission’s treasure.

Like their earthbound counterparts, astronauts make junk in their day-to-day lives, but different us; they can’t just bag it and abscond it on the curb.

"If NASA doesn't do something about it, then the spacecraft will become like a landfill, with the astronauts totaling waste to it all day."
Each tile is just over a centimeter broad, roughly 20 cm in diameter — which is a bit bigger than a normal compact disk — and made from about a day’s worth of rubbish.

Mary Hummerick, another microbiologist working on the project, sees possible in all the plastic packaging the astronauts discard.

If the plastic content of the disks is high enough, "they could really shield radiation," she said. NASA’s website explains that the strips could be arranged to shield the astronaut’s sleeping region or strengthen the spacecraft’s "storm shelter."

If all goes as intended, the end product could be particularly significant for crews living in space for up to two years — which is, NASA points out, the anticipated period of a Mars mission.

"If the instance and temperature tests seem to be achieving what we want, we'll go to long-range storage space testing," said Hummerick.

NASA Voyager 1 Encounters ‘magnetic highway’ in Deep Space

NASA’s Voyager 1 spacecraft has entered a new region at the remote reaches of our solar system that scientists refer to as a magnetic highway for charged particles because our Sun’s magnetic field outlines are linked to interstellar magnetic field lines.

Scientists feel this new region is the last area the spacecraft has to cross before reaching interstellar space. This link allows lower-energy charged particles that start from within our heliosphere, or the bubble of charged particles the Sun blows around itself, to zoom out and allows higher-energy particles from outer to stream in.

 Although Voyager 1 still is within the Sun’s atmosphere, we now can taste what it’s like on the exterior because the particles are zipping in and out on this attractive highway, said Edward Stone

 We consider this is the last support of our trip to interstellar space. Our top guess is its probable just a few months to a duo years away. The new region isn’t what we expected, but we’ve come to expect the unexpected from Voyager, he stated.

Since December 2004 when Voyager 1 crossed a tip in space called the termination shock, the spacecraft has explored the heliosphere’s outer layer, called the heliosheath.

In this area, the stream of charged particles from the Sun known as the solar wind suddenly slowed down from supersonic speeds and became turbulent. Voyager 1’s atmosphere was consistent for about five and a half years. The spacecraft then detected that the external speed of the solar wind slowed to zero.

Hubble space telescope helps discover most remote galaxy

Astronomers have revealed what is probably the most remote galaxy yet seen in the Universe by combining the power of the NASA/ESA Hubble Space Telescope, NASA’s Spitzer Space Telescope and one of nature’s zoom lenses. The object offers a glance back into a time when the world was only 3% of its present age of 13.7 billion years.

We see the recently discovered galaxy, named MACS0647-JD, as it was 420 million years after the Big Bang. Its light has travelled for 13.3 billion years to reach Earth, which corresponds to a redshift of around 11.

This is the newest discovery from the Cluster Lensing and Supernova review with Hubble, which uses enormous galaxy clusters as cosmic telescopes to enlarge remote galaxies behind them, an effect called gravitational lensing

Along the way, 8 billion years into its trip, the galaxy’s light took a detour along many paths around the enormous galaxy cluster MACS J0647.7+7015. Due to the gravitational lensing, the team observed three magnified images of MACS0647-JD with Hubble.

The cluster’s gravity boosted the light from the distant galaxy, making the images show far brighter than they otherwise would, although they motionless appear as tiny dots in Hubble’s portrait.

The estimated mass of this baby galaxy is roughly equal to 100 million or a billion suns, or 0.1-1% the mass of our Milky Way’s stars. “This object may be one of many building blocks of a galaxy,” Dan Coe, lead author of the study said.

The object is so little it may be in the first stages of galaxy formation, with analysis showing the galaxy is less than 600 light-years across. For contrast the Milky Way is 150 000 light-years across.

NASA's Cassini Space Probe at Saturn celebrates 15 years in space

NASA’s Cassini spacecraft marked 15 years in space Monday (Oct. 15), and the well-traveled probe won’t prevent studying Saturn and its many moons anytime soon.

Cassini has logged more than 3.8 billion miles since its launch on Oct. 15, 1997, researchers said. The spacecraft has made many contributions since arriving at Saturn in July 2004, including discovering water-ice geysers on the moon Escalades and snapping the primary views of the hydrocarbon lakes on Saturn’s biggest moon Titan.

During its time in space, the Cassini probe has sent home about 444 gigabytes of systematic data, including more than 300,000 images. Researchers have published more than 2,500 documents based on Cassini data so far, NASA officials said.

Cassini’s operators have sent it to call more than a dozen of Saturn’s 60-plus moons in the last eight years, and they sometimes ask the probe to find shots of the planet’s poles. Planning out such a pushy flight path is difficult, particularly given the gravitational influences of Saturn’s moons and Cassini’s incomplete fuel supply, mission managers said.

In November 2016, the probe will embark on a sequence of orbits that take it ever faster to Saturn. These orbits will begin just exterior Saturn's F ring, the outermost of the major rings, researchers said.

In April 2017, a close meet with Titan will throw Cassini on a pathway that will take it in Saturn’s innermost ring, just a hair away from the top of the huge planet’s atmosphere. Cassini will build 22 such close passes, and then a gravitational tug from a last, distant flyby of Titan will seal the spacecraft’s fate. It will crash into Saturn on Sept. 15, 2017.

The $3.2 billion Cassini-Huygens task is a collaboration involving NASA, the European Space Agency and the Italian Space Agency. The Cassini spacecraft ferried a probe called Huygens, which landed on Titan in January 2005. Huygens survived its thrust through the enormous moon’s broad atmosphere and sent information back to Earth for about 90 minutes after moving down.

NASA's Space Launch System rejoice: Powering Forward

NASA's Space Launch System
NASA is powering ahead toward a brand new destinations in the solar system. This week marks one year of development since the formation of the Space Launch System (SLS), the nation's next pace in human examination efforts.

On Sept. 14, 2011, NASA announced a new ability for America's space program: a heavy-lift rocket planned to take the Orion spacecraft and send astronauts beyond into space than still before.

And now, one year afterward, NASA has made swift development improving on existing hardware, testing and developing new mechanism, and paving the method for a new launch vehicle. The SLS will build human examination of deep space an actuality and make new possibilities for systematic detection.

The SLS is a national ability and will be the biggest rocket ever built, providing the authority we want to really explore beyond our present limits," said Todd May, Space Launch System program manager. "Not only will it take us beyond small Earth orbit, but it will get us there faster."

"Our aim was to become a leaner and more proficient program, based on lessons learned from earlier successes by the agency," May said. "But even more significant is to build a secure vehicle for our astronauts and one that can keep up exploration for years to come.

When Orion flies for the first time, SLS also will trial the spacecraft payload integration adapter ring. Engineers and machinists at Marshall are building this part of the rocket, which will mate the spacecraft to the Delta IV stand-in for SLS during Orion's trial flight in 2014 and the rest of the Space Launch System in 2017.

The adapter ring was future for both applications as a model of NASA's obligation to affordable solutions for the human examination of space.

NASA's traveler 'dancing on edge' of outer space

In a lecture marking the approaching 35th centenary of the Voyager project, Ed Stone said it could be "days, months or years" before it lastly breaks into interstellar space.Earlier this year a surge in a key pointer fueled hopes that the craft was nearing the so-called heliopause, which inscription the limit between our solar system and external space.

Scientists were intrigued in May by an enlarge in cosmic waves hitting the spacecraft, which for decades has snapped images of the Earth and other planets in the solar system as it has made its long trip into external space.But measurements since then have fluctuated up and down, signifying that, while the ability is near to the edge, it may tranquil not get there for some time.

"Crossing into interstellar space -- that will be a significant instant when the first object launched from Earth finally leaves the fizz," he said. Before May's rush in space rays researchers had said they projected Voyager 1 would leave the solar system and enter interstellar space -- between the end of the Sun's pressure and the next star system -- within two years.

NASA has described Voyager 1 -- today 11 billion miles (18 billion kilometers) away from the Sun -- and its cohort Voyager 2 as "the two most far-away active representatives of civilization and its wish to discover."

The scientists scheming Voyager 1 -- whose 1970s technology means it has only a 100,000th of the computer recollection of an 8 gigabyte iPod Nano -- determined to turn off its cameras after it approved Neptune in 1989, to protect control.

Shuttle Update for July 17

Shuttle Atlantis:

Shuttle Atlantis is being temporarily stored in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. Atlantis is scheduled to return to Orbiter Processing Facility-2 in August to complete transition and retirement processing. Atlantis is being prepared for public display at the Kennedy Space Center Visitor Complex and is scheduled to roll over to the complex in November. The Kennedy Space Center Visitor Complex is targeting a July 2013 grand opening for Atlantis’ new home.

Shuttle Endeavour:

On July 11-13, technicians in Orbiter Processing Facility-2, installed Endeavour’s replica shuttle main engines. Endeavour is being prepared for permanent public display at the California Science Center in Los Angeles. Its ferry flight to California is targeted for mid-September.

NASA's space shuttle fleet began setting records with its first launch on April 12, 1981 and continued to set high marks of achievement and endurance through 30 years of missions. Starting with Columbia and continuing with Challenger, Discovery, Atlantis and Endeavour, the spacecraft has carried people into orbit repeatedly, launched, recovered and repaired satellites, conducted cutting-edge research and built the largest structure in space, the International Space Station. The final space shuttle mission, STS-135, ended July 21, 2011 when Atlantis rolled to a stop at its home port, NASA's Kennedy Space Center in Florida.

As humanity's first reusable spacecraft, the space shuttle pushed the bounds of discovery ever farther, requiring not only advanced technologies but the tremendous effort of a vast workforce. Thousands of civil servants and contractors throughout NASA's field centers and across the nation have demonstrated an unwavering commitment to mission success and the greater goal of space exploration.

Tips to be Followed during Property Auction

When you find a property at auction, you will immediately think about the loss that the owner of the property must have gone through for the property to come for public auction. Auctions have become very common these days due to the financial crunch that came forth in the recent past leaving a lot of home owners to take this bitter decision. We can see auctions as one of the methods that are in practice for selling and buying properties.

Mostly auctions are considered as loss for the property owner and a big gain for the ones who take the property in auction for the best bid. But the actual truth is that there are equal possibilities for the seller and the buyer to enjoy profit if they follow a few points while managing a property auction. But the saddest point is that in many cases neither the buyer nor the seller gets profit but the agent who makes the best use of the situation gets the best revenue. It is a real blunder if you let the third party to earn money without any actual work done over the whole process. You will have to be well informed about a few points and tips to follow even before you plan to place your bid at a Property auction .

Before the Auction you will have to keep yourself informed about the actual rate of a similar property at the same location. Do a proper property valuation check before you buy or sell your property. Don't let people to under estimate the property value if you are the seller or the brokers to over value the property in case you are the buyer.

If you are going to buy a property, study about the property and find if it's useful for your and if it is your kind before going for a property auction to place your bid. When you want to buy a property you will have to find out about the repair works that needs to be done for the property after buying it. Do a rough calculation of the estimated amount that you will have to spend on the property after you buy it in the auction. See if the total amount falls within your budget, this will avoid any financial scarcity. 

If you are planning to earn some money out of the rent that you might get from the building, do check with people about the area value and the possible amount of rent that you can expect from the property after you repair it. Check if there is any major local development that might affect the property that you are going to place the bid for. During the auction, always try to make note of the other auctioneers moves so that you can place your bid effectively and never turn emotional. Keep yourself calm and plan thing well before you place your bid.

The Writer has written about Investment Houses and UK auction list. He has written many articles in various topics like Residential Home , and UK property auctions.

NASA Satellites Examine a Powerful Summer Storm

As a powerful summertime storm, known as a derecho, moved from Illinois to the Mid-Atlantic states on June 29, expanding and bringing destruction with it, NASA and other satellites provided a look at various factors involved in the event, its progression and its aftermath.

According to NOAA's Storm Prediction Center web site, a derecho (pronounced "deh-REY-cho") is a widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms. Damage from a derecho is usually in one direction along a relatively straight track. By definition an event is classified a derecho if the wind damage swath extends more than 240 miles (about 400 kilometers) and includes wind gusts of at least 58 mph (93 km/h) or greater along most of its length.

These storms are most common in the United States during the late spring and summer, with more than three quarters occurring between April and August. They either extend from the upper Mississippi Valley southeast into the Ohio Valley, or from the southern Plains northeast into the mid-Mississippi Valley.

The movie begins on June 28 at 1515 UTC (11:15 a.m. EDT) and ends on June 30, 2012 at 1601 UTC (12:01 p.m. EDT). In the animation, the derecho's clouds appear as a line in the upper Midwest on June 29 at 1432. By 1602 UTC, they appear as a rounded area south of Lake Michigan. By 2132, the area of the derecho's clouds were near Lake Erie and over Ohio expanding as the system track southeast. By 0630 UTC, the size appears to have almost doubled as the derecho moves over West Virginia, Maryland, Pennsylvania and Virginia. At 0232 UTC on June 30 (10:32 p.m. EDT), the Derecho was over the mid-Atlantic bringing a 100 mile line of severe storms and wind gusts as high as 90 mph to the region.

The process of a derecho can become self-sustaining as hot and humid air is forced upward by the gust front and develops more (reinforcing) towering clouds. When one adds in a rear low level jet stream, there is nothing to stop the repeating process.

NASA's Aqua satellite flew over the derecho on June 29 and June 30, using the Atmospheric Infrared Sounder instrument (AIRS) onboard to capture infrared imagery of the event.

The AIRS images for June 29, shows the crescent shape of the initial stage of the derecho as it gathered strength on the Michigan-Indiana-Ohio border and began its rapid eastward movement. "The AIRS infrared image shows the high near-surface atmospheric temperatures blanketing the South and Midwestern U.S., approaching 98 degrees Fahrenheit," said Ed Olsen of the AIRS Team at NASA's Jet Propulsion Laboratory.

Cassini Shows Why Jet Streams Cross-Cut Saturn

Turbulent jet streams, regions where winds blow faster than in other places, churn east and west across Saturn. Scientists have been trying to understand for years the mechanism that drives these wavy structures in Saturn's atmosphere and the source from which the jets derive their energy.

In a new study appearing in the June edition of the journal Icarus, scientists used images collected over several years by NASA's Cassini spacecraft to discover that the heat from within the planet powers the jet streams. Condensation of water from Saturn's internal heating led to temperature differences in the atmosphere. The temperature differences created eddies, or disturbances that move air back and forth at the same latitude, and those eddies, in turn, accelerated the jet streams like rotating gears driving a conveyor belt.

A competing theory had assumed that the energy for the temperature differences came from the sun. That is how it works in the Earth's atmosphere.

"We know the atmospheres of planets such as Saturn and Jupiter can get their energy from only two places: the sun or the internal heating. The challenge has been coming up with ways to use the data so that we can tell the difference," said Tony Del Genio of NASA's Goddard Institute for Space Studies, N.Y., the lead author of the paper and a member of the Cassini imaging team.

The new study was possible in part because Cassini has been in orbit around Saturn long enough to obtain the large number of observations required to see subtle patterns emerge from the day-to-day variations in weather. "Understanding what drives the meteorology on Saturn, and in general on gaseous planets, has been one of our cardinal goals since the inception of the Cassini mission," said Carolyn Porco, imaging team lead, based at the Space Science Institute, Boulder, Colo. 

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two on board cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute in Boulder, Colo

NASA readies to Hunt Black Holes with New Space Telescope

Nasa Black Hole Hunter
The U.S. space group is set to launch a telescope into space June 13 to seek out and learn black holes -- those still-mysterious space bodies that scientists consider lie at the spirit of every massive galaxy, including our own Milky Way.

Black holes have a gravitational pull so intense that not even light can flee from them. As gas, dust and stars are sucked in; the fabric accelerates and heats up, generating powerful X-ray beam emissions.

NASA is setting out to conduct a survey of the black holes in the universe. 

The U.S. space organization is launching a black hole seeker, a new telescope called NuSTAR, but properly known as Nuclear Spectroscopic Telescope Array. 

Paul Hertz is the director of NASA's astrophysics division. "Stars, nebulae and black holes emit X-rays of the type that we use in medical X-rays, and these cannot be detected from the outside of the Earth," explained Hertz.

Current telescopes offer images that show a universal glow from hundreds of massive black holes. NASA expects NuSTAR will be able to offer far improved images of black holes and other high-energy events when it surveys the extra-galactic sky.

NuSTAR launches, it will organize a 10-meter pole that will divide its mirrors from its detectors. That pole provides the distance required to focus the X-ray light into sharp images.

SpaceX journey should get NASA moving

A space capsule known as the Dragon touched down in the Pacific Ocean on Thursday.

After launching into orbit May 22, the capsule had performed a sequence of complicated exercises, docked with the International Space Station, dropped off more than 1,000 pounds of provisions and returned home bearing a load of science experiments.

It was the first profitable spacecraft to complete such an achievement. And the company that developed it, Space Exploration Technologies Corp., or SpaceX, was satisfied with a U.S. government agreement of $1.6 billion to fly 12 more supply missions.

Optimists saw a quick private company leveraging public investment, reducing prospect taxpayer burdens and heralding a new age of profitable space flight.

SpaceX’s accomplishment is inspiring, and private venture seems likely to transport much-needed competence to the government’s space program. The problem is that, even if this new company delivers all its promised benefits, U.S. space policy will still have no clear objective. In spite of many setbacks, SpaceX looks like a comparatively good deal for taxpayers.

Elon Musk, the company’s billionaire founder, says its missions will charge one-eighth what space ferry flights did, and a study last year by the National Aeronautics and Space Administration set up that SpaceX spent far less than what NASA would have to expand the rocket that launched the Dragon capsule. Ambitiously, the company aims to take humans into space by 2015.

ISS Transit of Venus


In 1768, when James Cook sailed out of Plymouth harbor to observe the Transit of Venus in Tahiti, the trip was tantamount to a voyage through space. The remote island had just been "discovered" a year earlier, and by all accounts it was as strange and alien to Europeans as the stars themselves. Cook's pinpoint navigation to Tahiti and his subsequent observations of Venus crossing the South Pacific sun in 1769 have inspired explorers for centuries.

 One of those explorers is about to beat Cook at his own game.

High above Earth, astronaut Don Pettit is preparing to photograph the June 5th Transit of Venus from space itself.

 Because transits of Venus come in pairs that occur once every 100 years or so, humans have rarely had the chance to photograph the apparition from Earth, much less from Earth orbit.

"The Expedition 31 crew will be the first people in history to see a Venus transit from space, and Pettit will be the first to photograph one," says Mario Runco, Jr. of the Johnson Space Center (JSC). Runco, an astronaut himself who flew aboard three shuttle missions, is an expert in the optics of spacecraft windows. Along with his wife Susan Runco, who is the coordinator for astronaut photography at JSC, Mario is helping Pettit gather the best possible images of the transit.

Pettit will be pointing his camera through the side windows of the space station's cupola, an ESA-built observatory module that provides a wide-angle view of Earth and the cosmos. Its seven windows are used by the crew to operate the station's robotic arm, coordinate space dockings, and take science-grade photos of the Earth and sky. It's also a favorite "hangout" for off-duty astronauts who find the view exhilarating.

Pettit describes the camera system: "I'll be using a high-end Nikon D2Xs camera and an 800mm lens with a full-aperture white light solar filter."

This month's transit is the bookend of a 2004-2012 pair. Astronauts were onboard the ISS in 2004, but they did not see the transit, mainly because they had no solar filters onboard. Tiny Venus covers a small fraction of the solar disk, so the sun is still painfully bright to the human eye even at mid-transit. Pettit's foresight to bring a solar filter with him makes all the difference.

SpaceX launches historic Trip to space station

The US Company SpaceX on Tuesday became the first marketable outfit to send its own spacecraft toward the International Station with the launch of the cargo-bearing Dragon capsule.

Three, two, one and launch of the SpaceX Falcon 9 rocket, as NASA turns to the confidential sector to resupply the International Space Station," said NASA commentator George Diller, as the spaceship blasted off at 3.44 am .

The trial flight -- which should include a fly by and berthing with the station in the coming days -- aims to show that industry can reinstate US access to the ISS after NASA retired its space transport fleet last year.

The task was delayed on Saturday due to a defective engine valve in the rocket's main engine, but was repaired the same day.

California-based SpaceX, owned by billionaire Internet entrepreneur Elon Musk, is the primary of several US competitors to attempt sending spacecraft to the ISS with the aim of restoring US access to space for human travelers by 2015.

The company effectively test-launched its Falcon 9 rocket in June 2010, then made history with its Dragon launch in December of that year, becoming the first marketable outfit to send a spaceship into orbit and back.

Until now, only the space agency’s of Russia, Japan and Europe have been able to send deliver ships to the ISS.

NASA is Training up an Astronaut for asteroid mission

NASA is presently teaching astronauts to land on asteroids and hopes to send humans to one of the distant space rocks in about a decade, The Telegraph reported over the weekend. As in the picture Armageddon, one inspiration for the attempt is to figure out a way to obliterate or deflect a huge asteroid that could be on a collision course with Earth.

In June, a group of astronauts will start learning how to activate vehicles and move about on asteroids.

Major Tim Peake, an astronaut with the European Space Agency, told The Telegraph that a manned mission to intercept a received asteroid would be a last option but could prove necessary because even huge space objects can be hard to notice.

Peake, before a test helicopter pilot, told the newspaper that "an asteroid mission of up to a year is absolutely achievable" with technology that's now available or being developed.

Asteroids are primarily placed in a belt beyond the orbit of Mars, but some "near-Earth" substance swing closer to our planet—sometimes even within 100,000 miles or nearer, clearly, when they strike us.

 Still, The Telegraph renowned that a mission to call an asteroid would probably takes space explorers further from Earth than the 239,000 miles traversed by NASA's Apollo astronauts when they visited the Moon.

Aside from receiving about securely on the near-zero gravity conditions on an asteroid, landing on such little, fast-moving substance could show thorny.

NASA Telescope Sees the Light from an Alien Super- Earth’ 55 Cancri e

NASA's Spitzer Space Telescope has detected light emanating from a "super-Earth" past our solar system for the first time. While the planet is not habitable, the recognition is a notable step toward the greatest search for signs of life on other planets.

"Spitzer has astonished us yet again," said Bill Danchi, Spitzer program scientist at NASA head office in Washington. The planet, called 55 Cancri e, falls into a group of planets termed wonderful Earths, which are more enormous than our residence world but lighter than massive planets like Neptune.

The planet is about twice as large and eight times as huge as Earth. It orbits an intense star, called 55 Cancri, in a mere 18 hours.

Previously, Spitzer and other telescopes were able to learn the planet by analyzing how the glow from 55 Cancri distorted as the planet accepted in front of the star.

In the new study, Spitzer calculated how much infrared light comes from the planet itself. The 55 Cancri systems are comparatively close to Earth, at 41 light-years away. It has five planets, with 55 Cancri e the closest to the star and tidally protected, so one surface always faces the star.

Spitzer exposed the sun-facing surface is tremendously hot, indicating the planet probably does not have an extensive atmosphere to take the sun's warmth to the unlit side.

The telescope might be able to use a similar infrared technique to Spitzer to search extra potentially habitable planets for signs of molecules perhaps associated to life.

Private Company reschedules 1st Launch to Space Station to May 19

The private spaceflight corporation SpaceX has once again delayed the launch of its first commercial Dragon space capsule bound for the global Space Station, this time to May 19, to permit more time to complete final checks on the spacecraft's rocket.

The new launch date, announced now (May 4), and is the newest delay for SpaceX, which originally hoped to loft the Dragon capsule on its debut journey to the space station on April 30.

 Last week, the Hawthorne, Calif.-based Corporation postponed the launch to May 7 to permit more time for flight software checks. Yesterday, SpaceX officials said the May 7 date was improbable, but kept open a choice for a May 10 takeoff.

"SpaceX is requesting a May 19th launch goal with a endorsement on May 22 from the Cape Canaveral Air Force Station," SpaceX officials announced in a Twitter update today.

The newest setback pushes the Dragon launch well into May, meaning it will launch on the heels of a Russian Soyuz spaceship transport three new crewmembers to the International Space Station.

That Soyuz spacecraft will discharge off from Kazakhstan on May 14 and arrive at the space station on May 17.

 NASA astronaut Joe Acaba and Russian cosmonauts Gennady Padalka and Sergei Revin travel the Soyuz to the station to connect three other crewmates already aboard.

Hubble to Use Moon as Mirror to See Venus Transit


This mottled landscape showing the impact crater Tycho is among the most violent-looking places on our moon. Astronomers didn't aim NASA's Hubble Space Telescope to study Tycho, however. The image was taken in preparation to observe the transit of Venus across the sun's face on June 5-6.

Hubble cannot look at the sun directly, so astronomers are planning to point the telescope at the Earth's moon, using it as a mirror to capture reflected sunlight and isolate the small fraction of the light that passes through Venus's atmosphere. Imprinted on that small amount of light are the fingerprints of the planet’s atmospheric makeup.

These observations will mimic a technique that is already being used to sample the atmospheres of giant planets outside our solar system passing in front of their stars. In the case of the Venus transit observations, astronomers already know the chemical makeup of Venus's atmosphere, and that it does not show signs of life on the planet. But the Venus transit will be used to test whether this technique will have a chance of detecting the very faint fingerprints of an Earth-like planet, even one that might be habitable for life, outside our solar system that similarly transits its own star. , Venus is an excellent proxy because it is similar in size and mass to our planet.

The astronomers will use an arsenal of Hubble instruments, the Advanced Camera for Surveys, Wide Field Camera 3, and Space Telescope Imaging Spectrograph, to view the transit in a range of wavelengths, from ultraviolet to near-infrared light. During the transit, Hubble will snap images and perform spectroscopy, dividing the sunlight into its constituent colors, which could yield information about the makeup of Venus's atmosphere.

Hubble will observe the moon for seven hours, before, during, and after the transit so the astronomers can compare the data. Astronomers need the long observation because they are looking for extremely faint spectral signatures. Only 1/100,000th of the sunlight will filter through Venus's atmosphere and be reflected off the moon.

This image, taken with Hubble's Advanced Camera for Surveys, reveals lunar features as small as roughly 560 feet (170 meters) across. The large "bulls-eye" near the top of the picture is the impact crater, caused by an asteroid strike about 100 million years ago. The bright trails radiating from the crater were formed by material ejected from the impact area during the asteroid collision. Tycho is about 50 miles (80 kilometers) wide and is circled by a rim of material rising almost 3 miles (5 kilometers) above the crater floor. The image measures 430 miles (700 kilometers) across, which is slightly larger than New Mexico.

Because the astronomers only have one shot at observing the transit, they had to carefully plan how the study would be carried out. Part of their planning included the test observations of the moon, made on Jan. 11, 2012, as shown in the release image.

Hubble will need to be locked onto the same location on the moon for more than seven hours, the transit's duration. For roughly 40 minutes of each 96-minute orbit of Hubble around the Earth, the Earth occults Hubble's view of the moon. So, during the test observations, the astronomers wanted to make sure they could point Hubble to precisely the same target area.

Public Invited to Two Free Earth Day 2012 Events at NASA Goddard


NASA's Goddard Space Flight Center in Greenbelt, Md. is hosting two free events on April 18 in celebration of Earth Day's forty-second anniversary. Both events will take place at the NASA Goddard Visitor's Center on IceSat Road, Greenbelt, Md.

Often cited as the most-viewed photograph of all time, the view of Earth's disk from Apollo 17 is emblematic of our home planet as an isolated blue marble. Despite the ubiquity of the Blue Marble, few people realize NASA has viewed the Earth since the agency's creation. In this talk Rob Simmon of NASA's Earth Observatory will discuss the history of NASA's evolving views of Earth, from the first weather satellites to the latest climate missions, from the orbit of Mercury to the edge of the Solar System. He will also describe the techniques used to build images that simulate the view from space, including cloud-free global composites and a picture of the Eastern Hemisphere from NASA and NOAA's newest Earth-observing mission, Suomi NPP. Speaker: Robert Simmon, NASA's Earth Observatory
Length: 20 minutes

1 - 2 p.m. EDT -- See the broadcast presentation titled: "Beautiful Earth Multimedia Performance and Science Dialogue," on a big screen at the NASA Goddard Visitor Center Auditorium.

Join us on a musical and visual tour of Earth from space with interactive discussions through the Beautiful Earth program. Director and Musician Kenji Williams performs the BELLA GAIA ( multimedia show along with interactive discussions by NASA Earth Scientist Thorsten Markus and Native American Science Educator Jim Rock. The Beautiful Earth program highlights Earth's water in all of its forms: liquid, solid, and vapor, from the western scientific, indigenous, artistic, and multi-cultural points of view. The program simulates spaceflight for the public and reminds us of the beauty and inter-connectedness of Earth’s life systems. Students and teachers from across the country will interact live with the program.

Three days of NASA activities will also be held on the National Mall in Washington from April 20 through April 22. The agency's involvement includes free activities and exhibits open to the public.

Giant Prominence Erupts


A beautiful prominence eruption producing a coronal mass ejection (CME) shot off the east limb (left side) of the sun on April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT. The CME was not aimed toward Earth.
