But Jezero came out a victor as it offers promising sampling targets of at least five kinds of rock, including clays and carbonates that have high potential to preserve signatures of past life, as revealed by NASA in a press statement.
"The Mars community has long coveted the scientific value of sites such as Jezero Crater, and a previous mission contemplated going there, but the challenges with safely landing were considered prohibitive", said Ken Farley.
Knowing more about the ability for life to exist on Mars in the distant past could inform us about how life evolved on Earth.
Choosing a landing site this early permits the rover drivers and science tasks group to upgrade their plans for investigating Jezero Crater once the rover is securely on the ground.
The material carried into the delta from a large watershed may also contain a wide variety of minerals from inside and outside the crater, it added. It'll also have experiments to test technologies that future astronauts will need, such as producing oxygen from Mars' thin carbon-dioxide atmosphere, and the equipment that's needed to extract and store samples for future missions to pick up. The U.S.is the only country to have missions that have survived a Mars landing.
Mars landing comes down to final 6 minutes of 6-month trip
On the NASA channel-stream from JPL procedures directly without video the landing, but with the audio of all commands and confirmations.
Launching a probe to Mars took place on 5 may, 2018 with the help of the rocket Atlas V. Without consideration of the cost of the rocket and costs for partners, the mission cost about $500 million.
It's been numerous years really taking shape, however, NASA's Mars 2020 wanderer mission is right now in the home stretch. The image combines information from two instruments on NASA's Mars Reconnaissance Orbiter, the Compact Reconnaissance Imaging Spectrometer for Mars and the Context Camera.
"NASA has chosen Jezero Crater as the landing site for its upcoming Mars 2020 rover mission after a five year search", the space agency said late Monday. TRN will enable the "sky crane" descent stage, the rocket-powered system that carries the rover down to the surface, to avoid hazardous areas. It'll be heating up even further a week from today with the arrival of NASA's Mars InSight lander.
