(Mars polar-region probe launched by NASA in 2007 with lander)
Phoenix (i.e., Mars Phoenix)
was a mission launched in 2007 by NASA
to land on and study Mars.
It landed in 2008, operating for five months.
Since its landing site was in the polar region
with very harsh conditions,
it had been clear that years of operation would be unlikely,
and the primary mission specified three months.
