NASA's Mars Phoenix Lander bit the dust today (no pun intended). After five months performing scientific experiments that included digging, scooping, baking, "sniffing", and "tasting" the Martian soil, the seasonal changes in sunlight have ended the mission. The robot's solar panels are no longer generating enough light for the robot to operate. The robotic lander, which had its own Twitter account, posted a final tweet today that said, "01010100 01110010 01101001 01110101 01101101 01110000 01101000 <3" - binary for "triumph".
