Phoenix Mars Lander returns images, puts tools to work on Red PlanetMay 30th, 2008 - 11:38 am ICT by admin
Washington, May 30 (ANI): NASAs Phoenix Mars Lander, which touched down on the surface of the Red Planet on May 26, is returning more detailed images of Mars and is now preparing its instruments for science operations.
The latest image to be transmitted from the Phoenix is a 360-degree panorama of the frigid Martian world.
Weve imaged the entire landing site, all 360 degrees of it. We see it all, said Phoenix principal investigator Peter Smith, from University of Arizona, Tucson. You can see the lander in a fish-eye view that goes all the way out to the entire horizon, he added.
The Phoenix has also freed its nearly 8-foot robotic arm, tested a laser instrument for studying dust and clouds, and transmitted its second weather report on the evening of May 28.
We are now making plans for where to dig first, and what well save for later, said Smith.
Commands were communicated to Phoenix to rotate the robotic arms wrist to unlatch its launch lock, raise the forearm and move it upright to release the elbow restraint.
Were pleased that we successfully unstowed the robotic arm. In fact, this is the first time we have moved the arm in about a year, said Matthew Robinson of NASAs Jet Propulsion Laboratory in Pasadena, California.
The arm deployment brings the Phoenix mission to a significant milestone.
We have achieved all of our engineering characterization prerequisites, with all the critical deployments behind us, said JPLs Barry Goldstein, Phoenix project manager. Were now at a phase of the mission where were characterizing the science payload instruments. Thats a very important step for us, he added.
After a health check that tests the arm at a range of warmer and colder temperatures, the titanium and aluminum arm will soon be tasked with its first assignment: to use its camera to look under the spacecraft to assess the terrain and underside of the lander.
The robotic arm will later trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze what this part of Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.
Another milestone for the mission included the activation of the laser instrument called light detection and ranging instrument (lidar), which is designed to detect dust, clouds and fog by emitting rapid pulses of green laser-like light into the atmosphere.
Lidar data shows dust aloft to a height of 3.5 kilometers.
The weather at the Phoenix landing site on the second day following landing was sunny with moderate dust, with a high of minus 30 degrees Celsius and a low of minus 80. (ANI)
