NASA To Send Two More Helicopters To Mars For 2033 Sample Return

NASA and the European Space Agency (ESA) hope to take custody of the samples Perseverance has been patiently collecting and return them safely to Earth, and they'll need the help of two more helicopters. IFLScience reports: NASA and the ESA are collaborating on putting a lander on Mars that is capable of taking off again and making a rendezvous with an orbiter which will then bring the cargo back to Earth. Rather than collect its own samples, the return mission will take over those collected by Perseverance, and the biggest change to the plans lies in how that transfer will occur. The project has not got funding yet but the space agencies are refining their plans. In a quest for the backing they need new details have been announced, along with a return date -- 2033 -- only slightly further off than 1969 was when Kennedy promised a Moon landing "before this decade is out." Previously the Sample Return Lander was planned to carry a Sample Fetch Rover and its associated second lander. Instead, NASA and the ESA are now proposing to equip the lander with two helicopters based on the phenomenally successful Ingenuity. They will be able to traverse the gap between the Mars Ascent Vehicle and where Perseverance left them much more quickly and having two offers redundancy if one fails. There's also a possibility that Perseverance could deliver the samples directly to the Mars Ascent Vehicle if it is still operating when the ascent vehicle lands. If everything goes to plan the Earth Return Orbiter and Sample Retrieval Lander will launch in 2027 and 2028 respectively. Although delays are common for space missions, the fact Ingenuity has continued to operate -- and even set records for its flights -- well beyond its anticipated mission time has increased the sample return team's optimism.
