Yes, there's ice on Mars

"Ice!" screams NASA's Phoenix lander.

Katharine Sanderson

“Whoohoo! Was keeping my eye on some chunks of bright stuff & they disappeared! Sublimated! So it can't be salt, it's ice.” That's the triumphant verdict of the Mars lander Phoenix, which yesterday boldly declared, after 24 Martian days of scratching the planet’s surface, that yes, there is ice on Mars.

  • Exciting. Lets see if it's definitely not CO2 and if organics are mixed in. Maybe it's time to review the Viking data again. Could Martian life be ultra-quick to take advantage of the briefest moments of temp and humidity? Anyway, we'll see.
