Phoenix is Alive! Just in Time for Halloween

After an uncertain couple of days, NASA has regained contact with the ailing Mars lander. Yesterday, scientists announced they were having difficulty communicating with Phoenix after the on board electronics were switched into “safe mode” on Tuesday. It seems likely that the robot was switched into this low-energy state due to the increasingly cold weather — plus a Sun-blocking dust storm — triggering a low-power fault.

Although scientists were concerned they may not regain communications with the lander, they were able get in touch with Phoenix late on Thursday during a two hour period when the lander’s electronics were powered up. Now scientists know that Phoenix will automatically reboot itself every 19 hours, and then power up again for two hours to carry out very limited science duties.

NASA was able to transmit commands via NASA’s Mars Odyssey orbiter which passed overhead during this two-hour period of opportunity. This goes to show how little solar energy is being collected from the meagre sunlight as Mars enters winter (the Sun is very low on the Martian horizon, and it will soon drop out of sight, sealing the fate of Phoenix).

However, before Phoenix succumbs to a low energy coma, NASA is trying to get as many science activities out of it before it is frozen solid.

It also seems fitting that the highly successful NASA mission should come back from the brink of death on Halloween. So, “Happy Halloween Phoenix!” We all hope you last a few more weeks…
