NASA’s Curiosity Studies Mars Surroundings, Nears Drive


NASA’s Mars rover Curiosity has been investigating the Martian weather around it and the soil beneath it, as its controllers prepare for the car-size vehicle’s first drive on Mars.

The rover’s weather station, provided by Spain, checks air temperature, ground temperature, air pressure, wind and other variables every hour at the landing site in Gale Crater. On a typical Martian day, or “sol,” based on measurements so far in the two-week old mission, air temperatures swing from 28 degrees to minus 103 degrees Fahrenheit (minus 2 to minus 75 Celsius). Ground temperatures change even more between afternoon and pre-dawn morning, from 37 degrees to minus 132 degrees Fahrenheit (3 to minus 91 Celsius).

An instrument provided by Russia is checking for water bound into minerals in the top three feet (one meter) of soil beneath the rover. It employs a technology that is used in oil prospecting on Earth, but had never before been sent to another planet.
