Decide where NASA’s “RATS” go

Where will NASA go to test its prototype vehicles and suits? You decide!

 

During Desert RATS, engineers, scientists and astronauts test NASA prototypes in extreme conditions, here it is the Lunar Electric Rover (LER – see the EnjoySpaceTV video in “Find out more” at the end of the article). Today, this machine has been renamed SEV for Space Exploration Vehicle. Credit: NASA

NASA regularly organises what it calls Desert RATS (Research and Technology Studies) where engineers and scientists test equipment at locations on earth which in part provide conditions similar to those encountered on the Moon or Mars.

The devil is in the detail
Such simulations allow the practical assessment of the defects and benefits of future concepts studied by the American space agency (NASA).  Whether it is spacesuits, space exploration vehicles or robots able to cooperate with the astronauts (who are also involved in Desert RATS), NASA has developed plenty of ideas. However, what is the reality in the field? Is the new suit really practical, for example? Can the astronaut easily kneel down to collect a sample?  Do the connecting joints seize up with dust? So, the purpose of Desert RATS is to take the prototypes out of the research department and expose them to extreme locations such as deserts where they will be subjected to the heat, dust, hard rocks... and the demands of their users!

Because in space, a frequently used adage declares that “the devil is in the detail”, meaning bugs are often found in the small details that no-one had thought of.  Simulations like Desert RATS really help to detect these minute details which sometimes result in serious problems and even mission failures. In addition to equipment, NASA also tests its procedures and coordination strategies.

Vote and select the site for Desert RATS 2010
This year, an area in northern Arizona has been selected, but NASA is allowing internet users to choose the final site! The vote is taking place online until 8 August and the result will be announced on 16 August. The 2010 Desert RATS campaign will take place in September 2010.

On the internet, NASA is giving you the chance to explore the planned test sites for the 2010 Desert RATS campaign, using GigaPan panoramic images. The American agency will select the area that receives the most votes from internet users. Click on the image to visit the website. Credit: NASA
