NASA reconsiders approach to returning Mars samples to Earth

The Perseverance rover successfully landed on Mars in February 2021. The primary objective of this mission is to collect samples that could provide insights into the possibility of past life on Mars. Initially, NASA had planned a robust Mars Sample Return program to bring these samples back to Earth. However, the cost and timeline for this program have been revised. NASA Administrator Bill Nelson stated that the $11 billion Mars Sample Return program is too expensive and the launch would be delayed until at least 2030. The estimated cost now ranges between $8 billion and $11 billion. Despite these challenges, NASA continues to explore innovative methods for retrieving samples collected by the Perseverance rover in the future.
