Bright, frosty polar caps, and clouds above a vivid, rust-colored landscape reveal Mars as a dynamic seasonal planet in this NASA Hubble Space Telescope view taken on May 12, 2016, when Mars was 50 million miles from Earth. The Hubble image reveals details as small as 20 to 30 miles ...
1 英语翻译 NASA’s methodical approach to the exploration of Mars has not yet answered the questions of whether biological life forms ever emerged on Mars and whether,[presuming such life forms left fossil traces to begin with],those traces still exist in some moist recesses of the cold and ...
Now, NASA is aiming to come up with a less complicated and less expensive plan to get the samples back to Earth. For this, NASA is both tasking people within the agency to come up with a new plan and inviting contributions from private industry that could help make the mission a reality...
"About 100 minutes after the closest approach, Mars will reach its closest point to the trajectory of the comet and therefore pass close to the comet's debris trail," Vasavada said. "The best estimate is that Mars will pass just outside of the debris tail." However, less likely scenarios...

NASA’s Ingenuity Mars Helicopter scouted this ridgeline near the ancient river delta in Jezero Crater because it is of interest to Perseverance rover scientists. Enlarged at right is a close-up of one of the ridgeline’s rocky outcrops. The image was captured on April 23, during the rotorcr...
NASA's Viking 1 lander touched down on the surface of Mars in 1976, pulling off the first successful landing on the Red Planet. Its twin, Viking 2, landed six weeks later in a different Mars region. The Viking landers took the first close-up pictures of the Martian surface but found ...
Orbital and surface observations can shed light on the internal structure of Mars. NASA’s InSight mission allows mapping the shallow subsurface of Elysium Planitia using seismic data. In this work, we apply a classical seismological technique of inverti
These observations took advantage of the closest Earth-Mars encounter in nearly 60,000 years as Mars passed within 0.372 AU of Earth and subtended an apparent angular diameter of 25.1"; this is the closest the planet will come to Earth until the year 2287. We used four instruments on HST ...
