Space shuttle workers receive layoff notices

0 comments
Nearly 1,400 employees were sent layoff notices this week from NASA's space shuttle contractor, United Space Alliance.

Of those 1,400 employees, 902 workers in Florida will be laid off, according to United Space Alliance spokeswoman Kari Fluegel. This layoff is related to the shutdown of the space shuttle program, Fluegel said.

"Previously we let everyone know that this was coming today...this week is when we are notifying specific employees," Fluegel said. The job cuts won't take effect until October 1, but will also involve 478 workers in Texas and 14 in Alabama."Our work scope and our work content is slowly ramping down as we finish up tasks," Fluegel said.

"We have to scale down," Fluegel said. Because of high operating costs, the current space shuttles are being phased out and replaced by a new spacecraft that will travel beyond the International Space Station's orbit.

To finish off, a $100 billion project of two remaining flights are scheduled for the U.S. space agency, but Congress is considering new plans for NASA beginning October 1, which would add a third flight to the station next summer. If the third flight is scheduled, United Space Alliance won't come up short for employees after the October 1 cutback. "Planning for that additional flight is included with this process," Fluegel said.

More layoffs might be in United Space Alliance's future."We expect a smaller, but another lay off action" sometime next year, Fluegel said. After that, it depends on how many missions the station has next year, she added.

The current layoffs follow two previous cutbacks, one in October 2009 and the other in June 2010, totaling 743 shuttle workers. That makes the upcoming layoffs the largest cutback for United Space Alliance, totaling 1394.

NASA plans on-time shuttle liftoff despite snag

Engineers scrambling to repair broken hoses on latest Tranquility module

NASA is still hoping to launch the shuttle Endeavour in early February as engineers scramble to repair broken hoses on the new space station module set to travel aboard the orbiter.

Endeavour is slated to launch the latest Tranquility module to the International Space Station on Feb. 7 from Kennedy Space Center in Florida. But two of the module's four ammonia coolant hoses have unsuccessful standard pre-launch checks, forcing engineers to come up with a repair plan while others try to build new hoses from scratch, station managers said Monday.

"Folks are working very hard to get the hoses completed, checked out, certified [and] tested," said Pete Hasbrook. NASA manager for the Expedition 22 mission aboard the space station "We are still working toward the Feb. 7 launch date."

The Tranquility module will give additional living space for the crew on board the space station.

Broken hoses

The new module, like other space station rooms, utilizes liquid ammonia as a coolant to keep its computers and other electronic equipment cool in space. The coolant hoses are routed on the outer surface of the space station and must function at a pressure of 3,000 pounds per square inch (psi) to keep the ammonia supply liquid and moving, Hasbrook said.

But the two broken coolant hoses on Tranquility failed at a pressure of only 1,500 psi or so,it seems that a defect in the exterior braided-metal sheath covering the flexible hose, Hasbrook said. The metal braids began separating from the hose connector during the analysis, he added.

Red Planet Rising

0 comments

Happy New Year everyone! I wish all a safe, healthy and prosperous 2010 as we come into the second decade of the 21st Century!

2009 was a great year for space exploration as space and water telescopes dominated. Water was proven to exist on the Mars and Moon and is thought to be present in moons of Jupiter and Saturn. Hubble Space Telescope was upgraded and repaired and NASA's planetary hunting space telescope Kepler and newest infrared space telescope WISE were launched. Much will be happening in space this year and you will be capable to read all about it right here.

Mercury comes into sight the third week of the new year in the morning sky 45 minutes or so before sunrise. Prime time for the planet will be from the 15th to 30th when it will be about a fist-width above the eastern horizon. To see Mercury you require an unobstructed view of the horizon.

NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft has given us the most complete coverage ever of the planet closest to the Sun.

Venus remains out of view as it is too close to the Sun to be seen, but will begin to be visible next month at sunset.

Mars will be in the eastern evening sky rising at about 7 p.m. and will be at its brightest for the next 2 years. The Red Planet will be nearby to Earth on January 27 at a distance of 61.7 million miles. This is a much farther closest approach distance compared to 2003 when Mars was about half that distance from earth. Mars is effortless to spot as it is a bright dull orange color. Use the nearly Full Moon, which will be to the right of Mars, on the January 2 and again on January 29 as a guide to discover the Red Planet.

2009 – A year of triumph and tension for NASA!

0 comments

The year 2009 was a mixed year of triumph and tension for NASA – while the agency triumphed in terms of captivating momentous steps towards exploration beyond the Earth’s orbit and also perking up its International Space Station research; tension for the agency consequence from the winding down of its shuttle program and the uncertainty hovering over the future direction of US human spaceflight.

With 2009 marking important achievements, like the discovery of water on the moon and Mars that would facilitate future of space exploration, and a class of newly-identified ‘Super-Earth’ planets that might some day turn out to be more habitable than Earth, the likely-to-be-stellar-studded coming year would see a growing armada of current, new and revived space telescopes.

Among the other highs for NASA this year was the go ahead by a White House panel to the growth of commercial space taxi services for US astronauts; the launch of five shuttle missions bythe agency ; the 40th anniversary of the Apollo 11 mission that was launched in July 16, 1969; the launch of a new generation of space telescopes for unraveling long-standing mysteries of outer space; and the spotting of distant galaxies by the 19-year-old Hubble telescope.

Commenting on the triumphs of 2009, William Gerstenmaier, associate administrator for space operations at NASA, said: “This is a tremendous time in spaceflight. We've had a very victorious year, and we need to cherish that.”

Ares I-X Ready, Weather Remains Unfavorable

0 comments

At this morning's Ares I-X Launch Status Briefing, Launch Test Director Jeff Spaulding said the flight test vehicle is ready for Tuesday morning liftoff. "I'm very happy to report that we are tracking no problems and the vehicle is in great shape."

Weather Officer Kathy Winters offered less favorable news, reporting that there still remains only a 40 percent chance that the weather on Tuesday morning will cooperate. The issue will be a chance of clouds and precipitation in the area. There is a four-hour launch window, extending from 8 a.m. until 12 noon EDT. If weather scrubs Tuesday's attempt, the launch team will try again on Wednesday, maintaining the same launch window.

Today's preparations at Launch Pad 39B include final ordnance work and electrical testing, as well as testing of the range safety command transmitter. Later tonight, technicians will install the flight doors on the fifth segment simulator.

Launch countdown preparations in Firing Room 1 are scheduled for Monday, and the launch teams "call to stations" will come at 12:30 a.m. EDT on Tuesday.


Ares I-X Flight Test

Launch Vehicle: Ares I-X
Launch Date: Oct. 27
Launch Time: 8 a.m. EDT
Launch Pad: 39B
Launch Site: NASA's Kennedy Space Center in Florida

NASA's first flight test for the agency's next-generation spacecraft and launch vehicle system, called Ares I-X, will bring NASA one step closer to its exploration goals. The flight test will provide NASA with an early opportunity to test and prove flight characteristics, hardware, facilities and ground operations associated with the Ares I.
