NASA's Phoenix Spacecraft Reports Good Health After Mars Landing [Sends First Pictures]

PASADENA, Calif. -- A NASA spacecraft today sent pictures showing itself in good condition after making the first successful landing in a polar region of Mars.

The images from NASA's Mars Phoenix Lander also provided a glimpse of the flat valley floor expected to have water-rich permafrost within reach of the lander's robotic arm. The landing ends a 422-million-mile journey from Earth and begins a three-month mission that will use instruments to taste and sniff the northern polar site's soil and ice.

"We see the lack of rocks that we expected, we see the polygons that we saw from space, we don't see ice on the surface, but we think we will see it beneath the surface. It looks great to me," said Peter Smith of the University of Arizona, Tucson, principal investigator for the Phoenix mission.

Radio signals received at 4:53:44 p.m. Pacific Time (7:53:44 p.m. Eastern Time) confirmed that the Phoenix Mars Lander had survived its difficult final descent and touchdown 15 minutes earlier. In the intervening time, those signals crossed the distance from Mars to Earth at the speed of light. The confirmation ignited cheers by mission team members at NASA's Jet Propulsion Laboratory, Pasadena, Calif.; Lockheed Martin Space Systems, Denver; and the University of Arizona.

As planned, Phoenix stopped transmitting one minute after landing and focused its limited battery power on opening its solar arrays, and other critical activities. About two hours after touchdown, it sent more good news. The first pictures confirmed that the solar arrays needed for the mission's energy supply had unfolded properly, and masts for the stereo camera and weather station had swung into vertical position.

"Seeing these images after a successful landing reaffirmed the thorough work over the past five years by a great team," said Phoenix Project Manager Barry Goldstein of JPL. A key milestone still ahead is the first use of the lander's 7.7-foot-long robotic arm, not planned before Tuesday.

"Only five of our planet's 11 previous attempts to land on the Red Planet have succeeded. In exploring the universe, we accept some risk in exchange for the potential of great scientific rewards," said Ed Weiler, NASA associate administrator for the Science Mission Directorate, Washington.

Phoenix carries science instruments to assess whether ice just below the surface ever thaws and whether some chemical ingredients of life are preserved in the icy soil. These are key questions in evaluating whether the environment has ever been favorable for microbial life. Phoenix will also study other aspects of the soil and atmosphere with instrument capabilities never before used on Mars. Canada supplied the lander's weather station.

Transmissions from Phoenix have reported results after a check of several components and systems on the spacecraft. "Phoenix is an amazing machine, and it was built and flown by an amazing team. Through the entire entry, descent and landing phase, it performed flawlessly," said Ed Sedivy, Phoenix program manager at Lockheed Martin Space Systems Company. "The spacecraft stayed in contact with Earth during that critical period, and we received a lot of data about its health and performance. I'm happy to report it's in great shape."

Phoenix uses hardware from a spacecraft built for a 2001 launch that was canceled in response to the loss of a similar Mars spacecraft during a 1999 landing attempt. Researchers who proposed the Phoenix mission in 2002 saw the unused spacecraft as a resource for pursuing a new science opportunity. A few months earlier, NASA's Mars Odyssey orbiter discovered that plentiful water ice lies just beneath the surface throughout much of high-latitude Mars. NASA chose the Phoenix proposal over 24 other proposals to become the first endeavor in the Mars Scout program of competitively selected missions.

The signal confirming that Phoenix had survived touchdown and the transmission of the first pictures were relayed via Mars Odyssey and received on Earth at the Goldstone, Calif., antenna station of NASA's Deep Space Network.

The Phoenix mission is led by Smith at the University of Arizona with project management at JPL and development partnership at Lockheed Martin. International contributions come from the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; Max Planck Institute, Germany; and the Finnish Meteorological Institute.

It's not luck; we are just that DAMN good.

There, fixed it.

I halfway expected Phoenix’ fist photo to include a one rover welcoming committee.

More importantly, did they land near the flags left by the Apollo types?

(Tip of the hat to one of the lame brained female congressional types.)

Thanks for the spectacular photos.

Funny thing is, I have the same view when looking out into my backyard in Arizona.

And, instead of hoping to see tire tracks or earth-type debris, I was hoping there would be a bare footprint or two.

pristine wilderness that shouldn’t be spoiled by oil exploration

perhaps a planet in the advanced stages of global warming

We spent a few Billion dollars, and took pictures of the same dust and rocks that the Viking landers took back in 1976!!

2008

1976

Hint to NASA - there is no life on Mars.

LOL!

Let me know when they find life {6" under the surface} around the corner {tomorrow}.

P.S. you won't be pinging me with the news of life discovered there - ever.

This is unreal. The Mars Reconnaissance Orbiter actually caught a picture of it descending.

68 degrees north latitude, 234 degrees east longitude.

Why does east longitude go beyond 180 degrees?

Global warming. Solar System Warming.

Ah, but don’t you see that glint off in the distance?

Yes, I saw that picture during the briefing that ended a little while ago. It is absolutely astounding. I was floored when the guy was explaining it.

Just. Wow.

It certainly says something about our country, that not only can we conduct combat operations across our planet, but also - simultaneously - conduct surface operations with multiple vehicles on another planet. No other country has ever come close.

Let me see. I get an advanced science/engineering degree. I get a job at NASA. I dream up neat things to do in space. I get taxpayers to fund my project. I carry out the mission. Then I do it all over again.

Clearly, I missed my calling.

I totally agree...NO LIFE ON MARS...the FReeper moonbats seem to lose it when such statements are made.

I believe it’s a virtual certainty.
