It is difficult to land on Mars. So you want to see tomorrow when perseverance (formerly called Mars 2020) becomes the first artificial landing object to land on the red planet after the Insight Mars lander in 2018. Due to the land in the Jezero Crater north of the equator of Mars, Perseverance carries many tools of science instruments to collect soil samples and find signs of ancient life. It’s equipped with state-of-the-art audio visual technology that let us see and hear – for the first time – it’s like touching another world. It will be exciting! NASA TV’s live coverage of the event will begin tomorrow, February 18, at 2:15 p.m. EST (19:15 UTC); The landing will take place at about 3:55 EST (20:55 UTC).
Where to watch: NASA TV, YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion and Theta.tv.

Innovative cameras The microphone on Mera and Drata will capture most of its main entrance, descent and landing process. This process, sometimes known by space engineers Seven minutes of terror, Is considered by many to be the most important and dangerous part of this mission.
According to NASA, engineers expect to receive notification of the main targets for landing at the following estimated times. Due to the distance that the signals have to travel from Mars to Earth, these events actually occur on Tuesday 11 minutes earlier than 22 seconds before. The exact timing of these landmarks listed above can be affected by a variety of factors, including the properties of the Martian atmosphere, which is difficult to predict until the spacecraft actually flies.
– Cruise Stage Separation: The part of the spacecraft that has been flying perseverance – NASA’s ingenious Mars helicopter attached to its belly – will pass through the entry capsule through space at 3:38 pm EST (differently) for the last 6/2 months. 12:38 pm PST, 20:38 UTC).
– Atmospheric entry: The spacecraft is expected to reach the top of the Martian atmosphere traveling at about 12,100 miles per hour (19,500 kph) at 3:48 p.m. (12:48 PST, 20:48 UTC). Is.
– Peak heating: Friction from the atmosphere will heat the bottom of the spacecraft to a temperature of about 2,370 degrees Fahrenheit (approximately 1,300 degrees Celsius) until 3:49 pm EST (12:49 pm PST, 20:49 UTC).
– Parachute Deployment: The spacecraft will deploy its parachute at supersonic speeds at 3:52 pm EST (12:52 pm PST, 20:52 UTC). The exact deployment time is based on the new range trigger technology, which improves the accuracy of the spacecraft’s ability to hit the landing target.
– Heat shield separation: The protective bottom of the entry capsule will separate about 20 seconds after parachute deployment. This allows the rover to use radar to determine how far away from the ground it is and uses its terrain-relative navigation technology to find a safe landing site.
– Separating the back shell: The rear half of the entry capsule attached to the parachute from the rover and its “jetpack” (known as the descending phase) will :: 54 EST (12:54 pm PST, 20:54 UTC). The jetpack will use retrorockets to slow down and get to the landing site.
– Touchdown: The descending stage of the spacecraft, using the Sky Crane maneuver, will bring the rover down to the surface on nylon tethers. The rover expects human walking speeds (about 1.7 miles per hour, or 2.7 kph) on the surface of Mars at around 3:55 pm (12:55 pm PST, 20:55 UTC).

The rover will hit the Martian atmosphere traveling at about 12,000 miles per hour (19,000 km), and its protective heat shield helps slow it down. Then, at an altitude of about 1 mile (1.5 km), the landing module will set its engines on fire, while the new terrain-related navigation system will proceed to identify a safe landing site. Essentially, it will scan and analyze the following area, then match the map to its database and prepare for the touchdown.
A 70-foot (21 m) diameter parachute will be deployed to slow down the craft, bringing its landing to a crawl, before the sky crane rover can begin to bring the rest down to the ground. The Sky Crane is the same hovering-landing system used by Curiosity, and a fully autonomous system designed to give rovers a softer, softer landing (hopefully).
Design wise, the Rover Curiosity is very similar to the Rover, currently in Gail Crater, but has some science equipment. While Curiosity focuses on finding evidence of a past living space that has done so, diligence is looking for direct evidence of life. This will be the first such mission since the Viking 1 and 2 Landers in the late 1980s / early 1980s.
Diligence’s surprisingly new cameras will take more of this whole process. The camera mounted on the rear shell of the spacecraft is pointed upwards. It will record the parachute deployment scene as it slows down. After that, it has a down-pointing camera on the descending stage, which will make its first touch-contact with the ground on Mars. This service of technology will provide us with the most detailed video and photo records of landing in the neighboring world. Lori Glaze, head of the planetary science division at NASA’s Directorate of Science mission, told reporters:
We are able to see ourselves landing on another planet for the first time.
There will be no live stream of footage, as we are accustomed to the events of the International Space Station and launching rockets from Earth. This is due to a delay in the data relay from Mars to Earth, which is even slower than the old dial-up connections. But using the Mars Reconnaissance bitwriter, we can get a glimpse of the Earth’s surface, which can share at least low-resolution images with us immediately after landing. In addition, we will also receive live feeds from Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena, California. We are left with some iconic images from the Curiosity landing footage (insert) Bobak Firodosi). Of course, the coronavirus protocol on mission control will still be in effect, but even a potential epidemic is unlikely to dampen the celebrations. Matt Wallace, Deputy Project Manager at Drata, said:
I don’t think Covid will be able to get us to jump from top to bottom and fist bumping. Even once we get this thing safely on the surface, you will see a lot of happy people.

To date, only eight successful Mars landings have taken place: Viking 1 and Viking 2 (both 1976), Pathfinder (1997), Spirit and Opportunity (both 2004), Phoenix (2008), Curiosity (2012) and Insight (2018).
The Soviet Union is the only other country to have successfully landed a spacecraft on Mars. That was in 1971 and 1973.
On the other hand, once there, Mars missions can last for years, and Earth robot rovers spend years orbiting Mars. For the first time, NASA will try something new with the Drata mission; It will drop a small helicopter into thin Martin air. Helicopters are called ingenuity. He will try to scout around a small planet, trying to target interesting places for future Mars missions.
NASA chose the Jezero Crater as the landing site for the Perseverance Rover for good reason. Scientists believe that the field was flooded at one time and billions. Billion billion years ago the ancient water was a river delta. The rivers of the river overflowed over the pit wall and formed a lake, carrying the clay minerals around it. Microbial life could have survived in pits during this one or more wet periods, and if so, traces of their remains can be found in the lake shore or in the silt along the shore. Scientists will study how the region was formed and developed, find traces of past life and collect samples of Mars rock and soil that may preserve these signs. The selection process for the landing site involved members of the mission team and scientists from around the world, who carefully examined the locations of more than 60 candidates. But after a full five-year study of potential sites, each with its own unique characteristics and appeal, Jezero reached the top.
In preparation for the Perseverance landing, NASA offers landing resources, ways to participate, social opportunities and more. Download posters, stickers, faxesheets, mission patches and more.

Bottom line: Tomorrow, with land in the Jezero Crater, NASA’s Perseverance Rover will carry science instruments to collect soil samples and find signs of ancient life. It will also use audio visual technology and is like seeing for the first time in the world and touching another world for the first time. How to watch live coverage of Personal Landing.
