Curiosity: Two Hours to Touchdown
Curiosity — NASA’s new Mars Science Laboratory — is due to land in Mars’ Gale Crater in two hours. The new scientific knowledge the rover will provide is sufficient cause for excitement, but the design of the landing process is pretty cool in its own right. (And, of course, if there’s not a successful landing, there will be no science at all.) Be sure to watch the video above, courtesy of the Jet Propulsion Laboratory, to see what I’m talking about.
Also, from the website:
NASA’s Mars Science Laboratory spacecraft is healthy and right on course for a landing in several hours that will be one of the most difficult feats of robotic exploration ever attempted.
Emotions are strong in the control room at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., as the hours and miles race toward touchdown of the car-size Curiosity at about 10:31 p.m. PDT tonight (about 1:31 a.m. Aug. 6, EDT).
“Excitement is building while the team is diligently monitoring the spacecraft,” said Mission Manager Brian Portock of JPL. “It’s natural to get anxious before a big event, but we believe we are very well prepared.”
Descent from the top of Mars’ atmosphere to the surface will employ bold techniques enabling use of a smaller target area and heavier landed payload than were possible for any previous Mars mission. These innovations, if successful, will place a well-equipped mobile laboratory into a locale especially well-suited for this mission of discovery. The same innovations advance NASA toward capabilities needed for human missions to Mars.
At the critical moment of Curiosity’s touchdown, controllers and the rest of the world will be relying on NASA’s Mars Odyssey orbiter to provide immediate confirmation of a successful landing. Odyssey will turn to point in the right direction beforehand to listen to Curiosity during the landing. If for any reason that turn maneuver does not work, a successful landing cannot be confirmed until more than two hours later.
The landing will end a 36-week flight from Earth and begin at two-year prime mission on Mars. Researchers will use Curiosity’s 10 science instruments to investigate whether Martian environmental conditions have ever been favorable for microbial life.
Good luck, Curiosity.
