The Phoenix Mars Lander

A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoenix. Phoenix's assignment is to dig through the Martian soil and ice in the arctic region and use its onboard scientific instruments to analyze the samples it retrieves.

Mars is a cold desert planet with no liquid water on its surface. But in the Martian arctic, water ice lurks just below ground level. Discoveries made by the Mars Odyssey Orbiter in 2002 show large amounts of subsurface water ice in the northern arctic plain. The Phoenix lander targets this circumpolar region using a robotic arm to dig through the protective top soil layer to the water ice below and ultimately, to bring both soil and water ice to the lander platform for sophisticated scientific analysis.

The complement of the Phoenix spacecraft and its scientific instruments are ideally suited to uncover clues to the geologic history and biological potential of the Martian arctic. Phoenix will be the first mission to return data from either polar region providing an important contribution to the overall Mars science strategy "Follow the Water" and will be instrumental in achieving the four science goals of NASA's long-term Mars Exploration Program.
- Determine whether Life ever arose on Mars
- Characterize the Climate of Mars
- Characterize the Geology of Mars
- Prepare for Human Exploration The Phoenix Mission has two bold objectives to support these goals, which are to (1) study the history of water in the Martian arctic and (2) search for evidence of a habitable zone and assess the biological potential of the ice-soil boundary.

Aboard the deck of the Phoenix spacecraft are a suite of science instruments representing some of the most sophisticated and advanced technology ever sent to Mars. The Phoenix Mission inherits a highly capable spacecraft partially built for the Mars Surveyor Program 2001 and important lessons learned from the Mars Polar Lander.

The spacecraft has several subsystems that are being updated, if necessary, with parts and software that will increase reliability. These subsystems include
- command and data handling, controlling the spacecraft's computer processing
- electrical power, consisting of solar panels, batteries, and associated converting circuits
- telecommunications, ensuring flow of data to and from Earth
- guidance, navigation, and control, assuring the spacecraft arrives safely at Mars
- propulsion, controlling trajectory correction maneuvers during cruise and thrusters during landing
- structure, providing the spacecraft framework and integrity
- mechanisms, enabling the movement of several spacecraft components
- thermal-control, using heat transfer to ensure proper temperature ranges on all parts of the spacecraft.

Launch Vehicle: Delta II
Launch Location: Cape Canaveral Air Force Station, Florida
Launch Pad: Space Launch Complex 17-A
Launch Date: Aug. 3, 2007
Launch Time: 5:35:18 a.m. EDT

The Delta II is designed to boost medium-sized satellites and robotic explorers into space. NASA selected a model 7925 for this mission, which is a three-stage rocket equipped with nine strap-on solid rocket boosters and a 10-foot payload fairing that will protect the spacecraft during launch.

it discovered the ice and then Mars winter came. They lost contact with it. Scientists are hoping that Phoenix will wake up once the temperature goes up.

Antarctica has a very similar environment (temperature wise) as mars, people live on Antarctica, as for pressure there is less pressure on mars then there is on earth, The average air pressure at the surface of Mars is 6 millibars (compared to 1013 millibars on Earth) so your quite wrong

I am very happy to see the vidoe A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoenix from you, hopefully the others also are happy for You

I Love The Video A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoenix It Can Increase My Knowledge

Nice Video A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoenix That You Share , So Very Nice Thanks You

[imegatrone]

I Really Like The Video A new space explorer is waiting in the wings and ready to take center stage: the Mars lander called Phoeni From Your

[bundawartini]

Your Video The Phoenix Mars Lander Is Very Useful Sharing

Thats why u get hurt when sending probe only I am challenging counter blance when next ganaration will landed on mars u need counter balance mass reduction how u fool will walk on the mars ur body weight will be 200 kilo u stupid.when u land only inside special suit which will be intelligent magnetic allow u to only walk inside space craft and a magnetic matt u fool

@wafi0123: What? How would that be possible on a planet half the diameter and only 1/10th the mass of Earth? Did you ever pay attention in school? I guess not.

[albedoshader]

@macanicable: Wow, and the radiation will destroy the rest of the world after that. You’re clearly a deep thinker.

They should create a spacial station and send it to mars from the earth and then arrive peolpe to mars, i think that it is easier
