Lujendra Ojha (b. 1990, लुजेन्द्र ओझा) is an American [1] planetary scientist. He, as an undergraduate under the direction of planetary geologist Alfred McEwen, discovered compelling evidence that water on Mars includes current, seasonal, surface liquid brine flows.
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
However, the lake bed had been covered over with lava flows, so evidence of past water was initially hard to detect. As the mission progressed and the Rover continued to move along the surface more and more clues to past water were found. On March 5, 2004, NASA announced that Spirit had found hints of water history on Mars in a rock dubbed ...
The Perseverance rover came across an odd stone on Mars, the likes of which NASA said has never been seen, that people are calling the 'zebra rock.' NASA's Perseverance rover found an unusual ...
Huge river valleys were found in many areas. Images showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers. [42] Areas of branched streams, in the southern hemisphere, suggested that rain once fell. [130] [131] The numbers of recognised valleys has increased through ...
If the comet ever comes around again, it might take until the year 2457.
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
The rover has journeyed across more than 20 miles, according to an interactive map that tracks its location and traverse path on NASA’s website. The samples, collected in titanium tubes after ...
