1. Sticking the landing One of Opportunity's most memorable feats was, appropriately, its first. Even now we treat the landing of a rover on Marsas a pretty big dealbut it was an especially epic event 15 years ago -- particularly because Opportunity's landing came just 20 days after the...
Simulations of atmospheric phenomena at the Phoenix landing site with the Ames General Circulation Model [1]聽Phoenix, the first NASA Mars Scout class mission, was designed to "follow the water" and study the polar region. Landing in late northern spring, Phoe... Steven,M.,Nelli,... - 《...
Opportunity tells a salty tale.(Mars) The latest word from the Mars Opportunity rover is that a sea of sorts once covered a large region on the equator of ancient Mars. RA Kerr 被引量: 0发表: 0年 Impact origin of sediments at the Opportunity landing site on Mars Mars Exploration Rover ...
Armed with this arsenal, Opportunity quickly found strong evidence that its original landing site once contained a large body of salty water. The physical appearance of the rocks and the discovery that many of them contained minerals that usually form in watery conditions revealed that the dry and...
about two and a half hours before Earth set at Terra Meridiani. On Mars it will be the latter half of southern summer. The landing ellipse is centered at 2.07 S, 6.08 W and is roughly 119 by 17 km oriented at 88 degrees. Terra Meridiani is also known as the "Hematite Site" because...
Opportunity's landing site lies in a part of Meridiani Planum with relatively little topographic relief. From a mission-safety point of view, Meridiani posed less risk than Gusev. Orbital surveys by the Mars Global Surveyor (MGS) and Mars Odyssey spacecraft told scientists that the Meridiani ...
NASA was intrigued by a layer of hematite that the orbiting Mars Global Surveyor spotted from above, located on the Meridiani Planum at the Martian equator, and decided that would be Opportunity's landing site. Because hematite (an iron oxide) often forms in a region that had water, NASA wa...
Here we'll focus on some of the stranger things Opportunity and Spirit have spotted on Mars. Blueberries on Mars Just a few months after the Opportunity rover arrived at the Red Planet, its cameras spotted this deceptively delicious-looking patch of rocks near the landing site. Not knowing ...
Found hematite, a mineral that forms in water, at its landing site. Discovered strong indications at Endeavour Crater of the action of ancient water similar to the drinkable water of a pond or lake on Earth. Caught Comet Siding Spring with its cameras ...
