The spacecraft Phoenix reached Mars' surface without incident, NASA officials say. The probe is set to make its first studies of the planet's northern polar region and help determine if Mars was ever able to support life.
A small science probe blazed through the salmon-colored skies of Mars on Sunday, touching down on a frozen desert at the planet’s north pole to search for water and assess conditions for sustaining life, NASA officials said.
The spacecraft, known as
Pulled by Mars’ gravity, Phoenix was tearing along at 12,700 mph (20,400 kph) before it entered the atmosphere, which slowed the craft so it could pop out a parachute and fire thruster rockets to gently float to the ground.
“It’s down, baby, it’s down!,” yelled a NASA flight controller, looking at signals from Mars showing that
Scientists found in 2002 that Mars’ polar regions have vast reservoirs of water frozen beneath a shallow layer of soil.
NASA attempted a landing on Mars’ south pole in 1999, but a problem during the final minutes of descent ended the mission.
Instead, like the 1970s-era Viking probes and the failed Polar Lander mission, it uses a jet pack to lower itself to the ground and fold-out legs to land on.
“We haven’t landed successfully on legs and propulsive rockets in 32 years,” said NASA’s space sciences chief Ed Weiler. “When we send humans there, women and men, they’re going to be landing on rockets and legs, so it’s important to show that we still know how to do this.”
