2022年9月17日 Perseverance in Jezero Crater’s Delta Image Credit: NASA, JPL-Caltech, MSSS, ASU Explanation: The Perseverance rover’s Mastcam-Z captured images to create this mosaic on August 4, 2022. The car-sized robot was continuing its exploration of the fan-shaped delta of a river that, billions of years ago, flowed into Jezero Crater on Mars. S...
2022年2月25日 Perseverance Sol 354 Image Credit: NASA, JPL-Caltech, Processing: Kenneth Kremer Explanation: This Navcam mosaic from Perseverance looks out over the car-sized rover’s deck, across the floor of Jezero crater on Mars. Frames used to construct the mosaic view were captured on mission sol 354. That corresponds to Earth calendar date February 17...
2021年04月03日 Ingenuity on Sol 39 Image Credit: NASA / JPL-Caltech / MSSS Explanation: The Mars Ingenuity Helicopter, all four landing legs down, was captured here on sol 39 (March 30) slung beneath the belly of the Perseverance rover. The near ground level view is a mosaic of images from the WATSON camera on the rover’s SHERLOC robotic arm. Near the cen...
2021年03月06日 Perseverance Takes a Spin Image Credit: NASA, JPL-Caltech, Mars 2020 Explanation: After arriving at Jezero Crater on Mars, Perseverance went for a spin on March 4. This sharp image from the car-sized rover’s Navcam shows tracks left by its six wheels in the martian soil. In preparation for operations on the surface of the Red Planet, its fi...
2021年02月16日 Perseverance: Seven Minutes to Mars Video Credit: NASA, JPL Explanation: How hard is it to land safely on Mars? So hard that many more attempts have failed than succeeded. The next attempt will be on Thursday. The main problem is that the Martian atmosphere is too thick to ignore — or it will melt your spacecraft. On the other hand, the atm...
2021年02月15日 Landing on Mars: Seven Minutes of Terror Video Credit: NASA, JPL Explanation: Starting Thursday, there may be an amazing new robotic explorer on Mars. Or there may be a new pile of junk. It all likely depends on things going correctly in the minutes after the Mars 2020 mission arrives at its new home planet and attempts to deploy the Perseverance...
This illustration shows Jezero Crater — the landing site of the Mars 2020 Perseverance rover — as it may have looked billions of years go on Mars, when it was a lake. An inlet and outlet are also visible on either side of the lake. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial li...
2020年8月22日 Yogi And Friends In 3D Image Credit & Copyright: IMP Team, JPL, NASA Explanation: From July of 1997, a ramp from the Pathfinder lander, the Sojourner robot rover, airbags, a couch, Barnacle Bill and Yogi Rock appear together in this 3D stereo view of the surface of Mars. Barnacle Bill is the rock just left of the solar-paneled Sojourner. Yogi...
Pilots Troy Asher and Stu Broce walk out of NASA’s Armstrong Flight Research Center’s (AFRC) hangar in Palmdale, California, toward the flight line. In addition to aeronautics research, Flight Operations personnel support such missions as the Mars Perseverance Rover, slated to launch in July 2020. Armstrong’s Building 703 in Palmdale opened in 2007 at ...
Shown in the artist’s rendering is the Mars Helicopter, a small, autonomous rotorcraft, will travel with NASA’s Mars Perseverance rover, currently scheduled to launch in July 2020, to demonstrate the viability and potential of heavier-than-air vehicles on the Red Planet. Destined to become the first aircraft to attempt powered flight on another p...
