NASA is reporting that the Phoenix lander, which arrived with much fanfare on Mars just over five months ago, is gradually being shut down.
The Phoenix has some life in it yet, but it's already outlived its original 90 day mission and now its power sources are failing.
The heaters keeping the Phoenix alive will be turned off one by one, keeping it running for as long as possible, until it can no longer be sustained.
Soon it will be over. The Phoenix will sit, still and quiet, waiting in the cold thin atmosphere of Mars.
It will wait for the day, hopefully soon, that we arrive in person on the red planet.
Then the Phoenix will be found, gathered up and preserved as a cherished memory of one of our earliest steps towards the stars.
