“Never before has a scientifically curated collection of samples from another planet been collected and placed for return to Earth,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington. “NASA and ESA have reviewed the proposed site and the Mars samples that will be deployed for this cache as soon as next month. When that first tube is positioned on the surface, it will be a historic moment in space exploration.”

The cache of samples – a duplicate set of the collection that Perseverance will retain on board – is one part of a robust plan to ensure mission success. The Perseverance rover will be the primary means to convey the collected samples to the Mars launch vehicle as part of the campaign. The Three Forks depot will serve as a backup, hosting the duplicate set. “Choosing the first depot on Mars makes this exploration campaign very real and tangible. Now we have a place to revisit with samples waiting for us there,” said David Parker, ESA director of Human and Robotic Exploration. “That we can implement this plan so early in the campaign is a testament to the skill of the international team of engineers and scientists working on Perseverance and Mars Sample Return. The first depot of Mars samples can be considered a major de-risking step for the Mars Sample Return Campaign.”

The first step in the campaign is already in progress. Since Perseverance landed at Jezero Crater on Feb. 18, 2021, the rover has explored 8.2 miles (13.2 kilometers) of Martian surface and collected 14 rock-core samples during its first two science campaigns. In the course of its first science campaign, the rover explored the crater’s floor – a former lakebed – finding igneous rock, which forms deep underground from magma or during volcanic activity at the surface. The second science campaign has been highlighted by the investigation of sedimentary rocks, formed when particles of various sizes settled in the once-watery environment.
