The Mars Sample Return Mission Will Take Two Helicopters to the Red Planet to Help Retrieve Samples - by ScottyJ_PhD
Sample return efforts are already in progress, as the Perseverance Rover is actively collecting samples from scientifically important sites in Jezero Crater on Mars, and has been since early 2021. The original plan was for Perseverance to cache the sample tubes for the fetch rover to collect at a later date. However, Perseverance is still going strong, and NASA expects that it will last long enough to deliver the samples to the ascent vehicle itself.
At a media press conference on July 27, Richard Cook, Mars Sample Return Program Manager at the Jet Propulsion Laboratory, indicated that the new helicopters will be distinct from Ingenuity in two ways. The first is that they will feature a set of small wheels rather than landing legs “that allow the helicopters to traverse across the surface on the ground as well as fly…and secondly, each of the helicopters will have a little arm that can reach down and grab onto the…sample tubes.
The helicopters, along with the lander carrying the ascent stage, are expected to launch from Earth in 2028 . After Perseverance and/or the helicopters retrieve the samples, the ascent stage will carry them to Mars orbit and rendezvous with the orbiter, before returning the precious core samples to Earth in 2033.
