NASA explores two methods for returning Mars samples over next 18 months

spacenews.com

NASA will study two different methods for returning samples from Mars over the next 18 months. One method uses existing "sky crane" technology, while the other involves new commercial landers. Both aim to bring samples back by 2035. The sky crane option is estimated to cost between $6.6 billion and $7.7 billion, while the commercial lander option is projected to cost $5.8 billion to $7.1 billion. Both methods will utilize a redesigned sample retrieval lander powered by a radioisotope generator. NASA's plans depend on Congress approving at least $300 million for the 2025 budget. The agency's timeline for launching the Earth Return Orbiter and sample retrieval lander is set for 2030 and 2031, respectively.
