‘NASA’s Seven Minute Terror’ at Mars Decent

In just 57 days, NASA’s Perseverance Rover will attempt to land on Mars. Mission controllers say it will be “seven minutes of terror”, as this new depiction displays in a dramatic way.

Created by NASA’s Jet Propulsion Laboratory, digital animation depicts major events during the Perseverance Rover’s entry, descending and landing (EDL). The video is just over three minutes In length, which is not much shorter than the landing stage, which should take about seven Minute. Fortitude launched on 30 July, And will perform EDL on February. 18, 2021 at 3:30 EST.

The $ 2.7 billion rover will land on the Jezero crater, the site of a former lake and river delta. Equipped with its many tools, Perseverance will look for signs of microbial life, study Martian weather and geology, and collect samples for a future mission to retrieve. Rover will also deploy Ingenuity, A small helicopter that is set to become the first manned aircraft to fly in an alien world.

Of course, persistence would have to prevent any landing for this to happen. Actually, Mars is notorious for ending missions before they have a chance to start an ESA failed A recent example is the Shiaparelli Mission in 2017.

The first phase of the EDL will see the rejection of the cruise phase, which hosts solar panels, radios and fuel tanks used during the Red Planet’s journey. Lineage phase, as Firmness As it approaches the atmosphere, it will fire small throws on its back to orient the vehicle properly, and proceed to face the heat shield. The descending state will then see the rover Career through a thin Martian atmosphere at speeds reaching 12,000 mph (19,312) kilometers per hour), accordingly To NASA. Should this stage go according to plan, the interior of the craft should not be hotter than room temperature.

Once a supersonic parachute moves at a speed of at least 1,000 mph (1,609 kilometers per hour). NASA will introduce a new system Range trigger, To determine the most optimal moment for a parachute to deploy, which should be some 240 seconds after atmospheric insertion. The heat shield will then be removed No longer needed Unraveling the rover in the Martian environment for the first time.

Another new piece of technology, called Terrain-Relative Navigation, Will use video cameras and maps to choose the safest location for a landing.

At maximum the parachute will slow the vehicle down to about 200 mph (322 kilometers per hour), Driven descent is required. When the firmness remains at 6,900 feet (2,100 m) above the surface, the craft will slow to 2 mph at a very slow speed in the rocket-powered descent phase. (3.2 kph)). A sky crane will then slowly reduce 2,260-Pound (1,025-Kilogram) Rover on the surface, which it will use a set of 21-foot-long (6.4-)Meter long) Cable. Once the landing is sensed, the sky crane will cut the cable, and then clean the target site.

In college Will happen Real The rover will be free to explore the Martian surface as the fun begins. The Perseverance Mission is expected to last for two years, but as exemplified, it c.Lasted a long time. NASA’s Curiosity Rover, for example, landed on Mars in 2012, and it is still going strong. We are very strongly looking forward to the mission, but first things first: it must survive those dreadful seven minutes of terror.
