Phoenix Lander

Definition

The Phoenix Lander was a robotic spacecraft sent by NASA to study the climate, geology, and the potential for life on Mars. It landed in the northern polar region of the planet in 2008 and conducted a variety of scientific experiments related to the presence of water and the potential for habitability on Mars.

5 Must Know Facts For Your Next Test

1. The Phoenix Lander was designed to study the climate and geology of the Martian northern polar region, with a focus on the potential for water and habitability.
2. The lander used a robotic arm to dig into the Martian soil and collect samples, which were then analyzed by onboard scientific instruments.
3. One of the primary goals of the Phoenix mission was to determine the presence and state of water ice in the Martian soil, as well as to study the chemical and mineralogical composition of the soil.
4. The Phoenix Lander was equipped with a meteorological station that provided valuable data on the Martian atmosphere, including temperature, pressure, and wind patterns.
5. The mission successfully operated for approximately 5 months, far exceeding its original 3-month design lifetime, before contact was lost with the lander due to the onset of the Martian winter.
