NASA announced on Tuesday, January 7, 2025, that it will explore two different landing options for its Mars Sample Return (MSR) program. This decision aims to maximize the chances of successfully bringing Martian rock and sediment samples to Earth.

The MSR program is a strategic initiative by NASA to better understand Mars, including whether it ever hosted life. The program involves collecting samples from the Martian surface and bringing them back to Earth for study.

The two landing options being explored are the “sky crane” method, which has been used successfully in previous missions, and a new approach leveraging commercial capabilities.

NASA’s decision to explore two options is driven by a desire to ensure the program’s success while also encouraging innovation and cost savings. The agency plans to select a single path forward for the program in the second half of 2026.

In the meantime, NASA will continue to collect samples from the Martian surface and prepare for the return mission. The agency is also evaluating ways to simplify the mission and reduce its complexity, such as using a radioisotope power system to provide power and heat.

The MSR program is a major undertaking that has the potential to change our understanding of Mars and its history. If successful, it will be a major milestone in the exploration of the Red Planet.
