NASA has made headlines this week by unveiling new findings from the Perseverance Mars rover, which has now collected 30 rock samples from the Jezero Crater, including a notable specimen called 'Sapphire Canyon' sampled in July 2024 on the crater’s edge. NASA convened a press conference on September 10, 2025, to detail the analysis of this sample, with participants from NASA Headquarters and leading planetary scientists discussing early conclusions and the rover's ongoing mission to uncover evidence of Mars’ ancient water activity. Perseverance continues to study uncollected geologic targets, operating with six empty sample tubes still available, and testing spacesuit materials to assess their durability for future human missions, all while providing critical weather data from the Martian surface, according to NASA's Science Mission Directorate.

China is accelerating its own Mars ambitions. In September 2024, Chinese space officials announced plans to move up the launch of their historic Tianwen-3 Mars sample return mission to 2028, aiming to bring Mars samples back to Earth by roughly 2031, potentially outpacing NASA's timeline. NASA, meanwhile, is reevaluating its own Mars Sample Return (MSR) plans after pausing work on the original mission in late 2023 due to ballooning costs. In early 2024, NASA announced it was considering updated options proposed by industry partners, aiming to return samples collected by Perseverance in the mid-2030s. This race to retrieve the first direct samples from Mars could shape the future of planetary science and international space competition.

Recent scientific work has injected new excitement into mission planning. A May 2025 publication from researchers at the University of California, Santa Barbara, demonstrated that SpaceX’s Starship could theoretically shorten the journey between Earth and Mars to just three to three and a half months using optimized trajectories, compared to the usual six to nine months. Although such fast transits would stress engineering constraints, especially during Martian atmospheric entry, the possibility opens a path for more agile crewed and cargo missions.

SpaceX kept itself in international Mars conversations by confirming in October 2024 its intention to launch uncrewed Starships to Mars in 2026, the next planetary alignment optimal for interplanetary transfer. The company’s stated goal is to demonstrate Starship’s ability to land and operate on Mars, which could pave the way for their first crewed attempt as early as 2028 or 2029. NASA has similarly integrated its Artemis lunar architecture into plans for human Mars exploration, officially targeting the 2030s for American astronauts on the Red Planet.
