2020 skickar NASA en ny expedition till Mars, med en ny marsbil - baserad på
den lyckosamma Curiosity (som likt Fingal Olsson fortfarande är uta och rör på
sig), men förbättrad. Raketen startar från jorden i augusti 2020 och är framme
i september 2021

"Mars 2020 will have better cameras and microphones as well as thicker wheels
to keep it from breaking down like Curiosity’s did. There’s also a new coring
drill and a ground-penetrating radar to look below the surface of Mars. Since
Mars 2020's primary objective is to look for signs of life, it will also have
features to analyze organic chemicals, including a device that will test the
ability to form oxygen on the planet for future colonization efforts. Some
rumored features that the researchers considered, however, were ultimately
rejected.
“We had been asked to study the possibility of bringing a helicopter with
us,” Kenneth Farley, the project scientist for Mars 2020, said. “But Mars 2020
is certainly not going to be flying a drone.”
Although the design for the 1,050 kilogram rover is finalized, there’s still
plenty to do before its ready for launch in four years. Not only do they have
to finish construction, NASA also has to select a landing site that will put
the rover within range of the most likely hotbeds of previous Martian life.
“There’s a very short [launch] window in 2020,” Farley noted. “If we don’t
hit it, we have to wait two years. So we’re working very hard to hit it.”
When the rover finally does hit Mars, the landing is going to be a
nail-biter. The rover will enter the planet’s atmosphere at 11,000 mph and will
use a combination of a supersonic parachute and above-ground rocket thrusters
to brake during its descent. If all goes well, one of the first things the
rover will beam back to us is footage of its (hopefully very soft) crash. And
then Mars 2020's real work can begin."
