Atmosphere checked, one Mars year before a landing

Sep 30, 2010
This artist's concept shows NASA's Mars Reconnaissance Orbiter, whose Mars Climate Sounder instrument has been profiling the Martian atmosphere for four years. The instrument has just begun a campaign to examine atmospheric conditions for the Martian season and hour when the next Mars rover will land in 2012.

(PhysOrg.com) -- In preparation for NASA's next rover landing on the Red Planet, one Mars year away, an instrument studying the Martian atmosphere from orbit has begun a campaign.

What will the be like when the next rover descends through it for landing in August of 2012?

An instrument studying the Martian atmosphere from orbit has begun a four-week campaign to characterize daily atmosphere changes, one Mars year before the arrival of the Mars Science Laboratory rover, Curiosity. A Mars year equals 687 Earth days.

The planet's thin atmosphere of carbon dioxide is highly repeatable from year to year at the same time of day and seasonal date during northern spring and summer on Mars.

The Mars Climate Sounder instrument on NASA's Mars Reconnaissance Orbiter maps the distribution of temperature, dust, and water ice in the atmosphere. with height indicate how fast air density changes and thus the rates at which the incoming spacecraft slows down and heats up during its descent.

"It is currently one Mars year before the Mars Science Laboratory arrival season," said atmospheric scientist David Kass of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "This campaign will provide a set of observations to support the Mars Science Laboratory engineering team and Mars atmospheric modelers. The information will constrain the expected climate at their landing season. It will also help define the range of possible on landing day."

During the four years the Mars Climate Sounder has been studying the Martian atmosphere, its observations have seen conditions only at about three in the afternoon and three in the morning. For the new campaign, the instrument team is inaugurating a new observation mode, looking to both sides as well as forward. This provides views of the atmosphere earlier and later in the day by more than an hour, covering the range of possible times of day that the rover will pass through the atmosphere before landing.

Obama and the dummycrat congress have practically cancelled the manned space flight program.
Actually, it looks like Obama and Congress agree with me.

Signed in on Wednesday "Obama's space plan also calls for astronauts to visit an asteroid by 2025 and then aim for a manned Mars mission in the 2030s. A heavy-lift rocket for those missions was slated to begin development in 2015."

About time.

Building another heavy-lift rocket?
The visit to the asteroid is to confirm long-term viability for mineral retrieval and further space exploration in terms of the next 50 years (id say).
A manned mission to mars seems to me more about the technology rather than the success which would be icing on the cake. But yes a manned mission is pointless without the technological/Historical/social rewards which would seem to be staggering.
