NASA plans to bring rock samples back from Mars with the help of two space helicopters

NASA has altered the Mars Sample Return Program meant to bring back the rock samples the Perseverance rover has been drilling and collecting from the Jezero crater in a big way. Instead of sending the Sample Fetch Rover to the red planet like originally planned, the program will make use of Perseverance itself and send over two helicopters based on the Ingenuity for backup. 

NASA and the ESA have been working together on the Sample Return Program over the past few years. The original plan was to send over the ESA-made Sample Fetch Rover to retrieve the samples and drive them back to a rocket, which will fly them up to be snatched by the Earth Return Orbiter. As The New York Times notes, though, the rover’s design became too big until it could no longer fit in one lander with the return rocket. NASA would have to use one lander for each of them.

But why do that when there are other, more affordable options? The Sample Return Lander isn’t scheduled to arrive on Mars until 2030, but NASA is confident that Perseverance will still be operational by then — after all, the Curiosity rover is …read more
