4 天之前 · Mars is one of the easiest planets to spot in the night sky — it looks like a bright red point of light. Despite being inhospitable to humans, robotic explorers — like NASA's Perseverance rover and Mars Reconnaissance Orbiter — serve as pathfinders to eventually get astronauts to the surface of the Red Planet.

2025年1月29日 · NASA is reimagining the future of Mars exploration, driving new scientific discoveries, and preparing for humans on Mars. NASA’s Mars Exploration Program will focus the next two decades on its science-driven systemic approach on these strategic goals: exploring for potential life, understanding the geology and climate of Mars, and preparation ...

2024年11月20日 · Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape. NASA missions have found lots of evidence that Mars was much wetter and warmer, with a thicker atmosphere, billions of years ago.

2025年3月26日 · NASA’s Perseverance rover landed on Mars in 2021 to search for signs of ancient microbial life and to help scientists understand the planet’s climate and geography. But another key objective is to pave the way for human exploration of Mars, and as part of that effort, the rover carries a set of five spacesuit material samples. ...

2025年2月7日 · Six Technologies to Get Humans to Mars. NASA is advancing many technologies to send astronauts to Mars as early as the 2030s. Here are six things we are working on right now to make future human missions to the Red Planet possible. Learn More

2025年3月19日 · The Mars 2020 Perseverance Rover searches for signs of ancient microbial life, to advance NASA's quest to explore the past habitability of Mars. The rover is collecting core samples of Martian rock and regolith (broken rock and soil), for potential pickup by a future mission that would bring them to Earth for detailed study.

10 小时之前 · NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

Mars is the fourth planet from the Sun – a dusty, cold, desert world with a very thin atmosphere. Mars is also a dynamic planet with seasons, polar ice caps, canyons, extinct volcanoes, and evidence that it was even more active in the past.

Mars is no place for the faint-hearted. It’s dry, rocky, and bitter cold. The fourth planet from the Sun, Mars is one of Earth's two closest planetary neighbors (Venus is the other). Mars is one of the easiest planets to spot in the night sky – it looks like a bright red point of light.

2025年3月24日 · Scientists analyzing pulverized rock onboard NASA’s Curiosity rover have found the largest organic compounds on the Red Planet to date. The finding, published Monday in the Proceedings of the National Academy of Sciences, suggests prebiotic chemistry may have advanced further on Mars than previously observed. Scientists probed an existing rock sample inside Curiosity’s Sample Analysis at ...
