NASA has announced a new approach to its Mars Sample Return Program, aiming to bring back the first Martian rock and sediment samples to Earth by 2026. The agency is exploring two different landing strategies simultaneously during the program’s development phase, fostering competition, innovation, and cost reduction.
The dual-track approach is designed to unlock the secrets of the universe and investigate whether Mars ever supported life. Ultimately, NASA will choose one strategy to move forward with, with the final design and confirmation expected in the latter half of 2026.
According to NASA Administrator Bill Nelson, pursuing two potential paths forward will result in significant cost savings compared to previous plans. The samples have the potential to revolutionize our understanding of Mars, the universe, and ourselves.
NASA is evaluating 11 studies from industry partners and experts on how best to return Martian samples to Earth. A strategic review team led by Dr. Maria Zuber has recommended a primary architecture for the campaign, including cost and schedule estimates.
The mission will allow scientists to study the planet’s geological history and climate evolution, shedding light on the early solar system and potential life on Mars. The landing platform will carry a smaller version of the Mars Ascent Vehicle, powered by a radioisotope system that can withstand dust storms.
Both options rely on ESA’s Earth Return Orbiter to capture the orbiting sample container in Mars orbit. A redesigned sample loading system simplifies backward planetary protection implementation, eliminating dust accumulation on the outside of the sample container.
The program aims to expedite Martian science and prepare for future human exploration of the Red Planet. With two competing strategies, NASA is poised to bring significant scientific breakthroughs back to Earth by 2026.
