NASA has altered the Mars Sample Return Program meant to convey again the rock samples the Perseverance rover has been drilling and accumulating from the Jezero crater in an enormous manner. Instead of sending the Sample Fetch Rover to the pink planet like initially deliberate, this system will make use of Perseverance itself and ship over two helicopters primarily based on the Ingenuity for backup.
NASA and the ESA have been working collectively on the Sample Return Program over the previous few years. The unique plan was to ship over the ESA-made Sample Fetch Rover to retrieve the samples and drive them again to a rocket, which is able to fly them as much as be snatched by the Earth Return Orbiter. As The New York Times notes, although, the rover’s design turned too huge till it may not slot in one lander with the return rocket. NASA must use one lander for every of them.
But why try this when there are different, extra inexpensive choices? The Sample Return Lander is not scheduled to reach on Mars till 2030, however NASA is assured that Perseverance will nonetheless be operational by then — in spite of everything, the Curiosity rover remains to be up and working virtually 11 years after it launched. Under their renewed plan, the Perseverance will drive as much as the lander to ship 30 rock samples that shall be loaded onto the rocket.
If something goes incorrect with Perseverance earlier than then, although, the lander would settle nearer to the rover after which the backup helicopters will fly over to retrieve the samples. While the helicopters are modeled after the Ingenuity, they’re going to have small wheels on the backside. These will enable them to drive as much as the samples which are sealed inside tubes and choose them up from the bottom the place the rover has dropped them.
The Ingenuity helicopter accomplished its first take a look at flight on Mars in April 2021. NASA wasn’t anticipating a lot from the helicopter, which was simply presupposed to show that flight on Mars is feasible. It was additionally solely presupposed to fly a handful of occasions throughout a one-month expertise demonstration, however it has completed 29 profitable flights thus far, with extra on the way in which. Ingenuity’s success has given NASA one other means to retrieve the dear samples Perseverance has been accumulating.
Dr. Thomas Zurbuchen, the affiliate administrator for NASA’s science directorate, mentioned throughout the press convention asserting the brand new Sample Return Program plans:
“We reached our determination primarily based on new research and up to date achievements at Mars that allowed us to contemplate choices that, frankly, weren’t out there to us one 12 months in the past or earlier than.”
The Earth Return Orbiter and Sample Retrieval Lander will take off within the fall of 2027 and the summer time of 2028, respectively. Their journey to and from the pink planet will take years, so the samples aren’t anticipated to reach on Earth till 2033.
