Another Mars location being considered for future helicopter mission

Global overview of potential Mars helicopter missions

In today’s May download of new photos from Mars Reconnaissnce Orbiter (MRO) I came across the picture to the right, reduced and sharpened to post here, and taken on April 2, 2024 by MRO’s high resolution camera. The scientists labeled it “Sample Rim Traverse Hazards at Possible Mars Helicopter Landing Site.” It was clearly taken as part of preliminary research to determine some potential landing sites for a future Mars helicopter mission.

Nor is this the first such location or region on Mars targeted for such a mission. As shown in the global map above of Mars, colored by the elevation data from MRO (blue is low and orange is high), two other candidate sites are being looked at as well. About a half dozen pictures have been taken inside the eastern end of Valles Marineris, exploring a helicopter mission there. In addition, MRO took for the same purpose a recent photo of the floor of Terby Crater, on the northern interior slope of Hellas Basin.

NASA/ESA revise plan to recover Perseverance core samples from Mars

NASA and ESA yesterday announced that the agencies have revised their plan to recover Perseverance core samples from Mars, dropping the launch of a rover to pick up the samples.

Instead, they have decided to use Perseverance to bring the samples to the return vehicle, which will also carry two small helicopters.

In 2030, if all goes as planned, the NASA lander will touch down near where Perseverance is working. The rover will drive over to the lander, and an ESA-built robot arm will extract the tubes one by one and place them inside a spherical container the size of a basketball. In early 2031, a rocket on the lander will loft the container into Mars orbit, where a return craft built by ESA will snare it, enclose it in several layers of shielding for safety, and then head for home. In 2033, a saucer-shaped descent pod will carry the samples down to the Utah desert.

If Perseverance gets into difficulties during its 9-year wait for company, controllers can instruct it to drop its cargo of sample tubes onto the ground, creating a second depot. If that happens, the helicopters come into play: they can fly up to 700 meters, land next to a sample tube—each weighs up to 150 grams—and, with wheels on the bottom their feet, roll over the tube and pick it up with a grabber. On returning to the lander, they will drop the tubes on the ground for the arm to pick up.

The change means that the rover the United Kingdom was planning to build will either be abandoned, or repurposed as a lunar rover.
