NASA to find out if Phoenix Lander still working

NASA is to find out whether its Mars exploration spacecraft, the Phoenix Lander, is still functioning or not, according to news reports on Wednesday.

The Phoenix Lander was landed on Mars on May 2008 in glancing for possible lives. After almost half a year of searching, the Spacecraft has presumably concluded its own life.

To continue its researching, NASA has now begun to make new efforts to know whether the Phoenix Lander is still in function.

"We have no hope that Phoenix has survived...but we certainly want to have a look," said Chad Edwards, chief telecommunications engineer at NASA's Jet Propulsion Laboratory.

NASA started Mars Exploration from the starting of 1964 and has 46 years of exploring experience until this year.

NASA's Rosetta 'Alice' Spectrometer Reveals Earth's UV Fingerprint

On November 13, the European Space Agency's comet orbiter Spacecraft, Rosetta, swooped by Earth for its third and final gravity support on the way to humankind's first rendezvous to orbit and study a comet in more detail than has ever been attempted.

One of the instruments aboard Rosetta is the NASA-funded ultraviolet spectrometer, Alice, which is designed to investigate the composition of the comet's atmosphere and surface - the first ultraviolet spectrometer ever to study a comet up close. During Rosetta's latest Earth flyby, researchers successfully tested Alice's performance by viewing the Earth's ultraviolet appearance.

"It's been over five years since Rosetta was launched on its 10-year journey to comet Churyumov-Gerasimenko, and Alice is functioning well," says instrument Principal Investigator Dr. Alan Stern, associate vice president of the Space Science and Engineering Division at Southwest Research Institute.

As one can see from the spectra we obtained during this flyby of the Earth, the instrument is in focus and illustrates the main ultraviolet spectral emission of our home planet. These data give a nice indication of the scientifically prosperous value of ultraviolet spectroscopy for studying the atmospheres of objects in space, and we're looking forward to reaching the comet and exploring its mysteries.
