During the recent installation of the final set of solar panels on the International Space Station, scientists LOCAD-PTS measured levels of pollution caused by microorganisms . This test may prevent human beings from contaminating the sands of Mars.
March 19, astronauts aboard the International Space Station (ISS, for its acronym in English) were tested to the presence of microbes before going for a spacewalk. This is the first time you perform a test of technology for planetary protection, one day, may prevent human beings from contaminating the sands of Mars.
"We did the tests using the LOCAD-PTS, a miniature biological laboratory for space travelers," explains Jake Maule, who is principal investigator of the experiment. LOCAD-PTS stands for English Language Lab-On-a-Chip Application Development Portable Test System (Portable Test System and Application Development Lab on a Chip).

"Before the crew of STS-119, Steve Swanson and Richard Arnold, leave the airlock of the International Space Station to install new solar arrays to the station, astronaut Sandy Magnus rubbed his gloves with one of the high-tech swabs LOCAD and then tested for the presence of microbes in the samples. The procedure was repeated when the astronauts re-entered the space station, more than six hours later ".. .
