NASA Insight will try its eighth Mars landing in a week: Barring the night for landing on Mars. The space shuttle made a try next week and will make its approach and landing through the right method, but NASA has pulled the stunt first, even if there are dozens of things to enter safely for insight, origin, and landing (ADL) will go well on the surface of the red planet.
NASA Insight will try its eighth Mars landing in a week
2:47 PM EST on November 26, Insight Lander will reach the top of the Martian atmosphere, about 125 kilometers (70 miles) from the surface, 5.5 kilometers per second (12,000 miles per hour). Uninterrupted silica heat shield of the craft will reach temperatures exceeding 1,500 degrees Celsius – hot enough for steel melting After three and a half minutes of atmospheric admission, the space shuttle will hit the ground on supersonic speed. A parachute will be deployed to reduce as much as possible, the heat shield will be jiton, and the space shuttle will start looking for land with a radar. About six minutes after killing the atmosphere, the lender will be separated from the rear shell – still traveling around 180 miles per hour – and will set fire to bring its retro rocket to the rest of the house, about a minute later Will touch the bottom
If all goes well- while engineers keep an eye on the control screen during “seven-minute panic,” unable to run alien craft in real-time – Insight will get relief in the Alicium Planitia on Monday after Thanksgiving and earthquake science. The study will be ready to begin an internal heat of Mars. NASA take comfort in the fact that such a landing has succeeded in the past, but when you are trying to rent a craft millions of miles away, it is impossible to prepare for every event.
Whenever the Mars landing approach approaches, space fans get a summary of the figures. Before landing curiosity, more than half of all Mars missions have failed. Before Europe’s Sommers launch, “more missions have failed: 28 flops compared to 28 successes.” After Exomer Orbiter was successful, but its leaders did not (at least, not completely): “On Mars, almost a dozen robot landers and rover missions were launched, only seven were successful.”
Statistics are dramatic. However, the story they tell is a bit dated. Failures the second half of the 20th century were a spectacular performance- Mangal 96, Mangal Supervisor, Mangal Climatic Climatic Orbiter and the loss of Mars Polar Lander are still stinging. However, Russia has not achieved complete success in Mars, NASA, European Space Agency (ESA) and Indian Space Research Organization (ISRO), but since Y2, all Mars in Mars have made too many orbital inclusions. In the works of China, India, and Japan, there are missions related to their second Mars planet, and the United Arab Emirates is making its first plan, not to mention the ambitions of many private institutions.
Mars class orbital insertion has become relatively regular in the 21st century, but Mars landing is still some of the most difficult deep space missions. ESA’s two successful classes included both small landers, which were never heard after touchdowns, although Xomoras Shiaparareli Lander had returned data almost all the way to the surface.
Three things make Mars more difficult than that for the moon landing or earth landing. First, unlike a Moon, Mars is too far for any ground-bound person to remain in the loop during the landing endeavor. Traveling from Mars to Earth takes time for the signal and is never less than nine minutes behind and usually it is longer, so long as we can hear a signal and answer that our space The vehicle has hit the top of the atmosphere, the final result, one side or the other, has already happened.
The second problem is the atmosphere of Mars. Too much and very little. On Earth, when astronauts and sample capsules come back from space, we can secure the space shuttle behind the heat shield and use the friction of atmospheric entry to slow the hypersonic craft in subsonic motion. Once the iron part is over, we can pop the parachute to reduce the speed and drift on a soft (or at least, live) touchdown on ground or water.
Mars’s atmosphere is quite thick to generate a flammable insertion, requiring heat shields, but it is too thin for a single parachute to slow down the spacecraft entering a safe landing speed. Curiosity hit Mars at the top of the planet in 2012; it was traveling 5.8 kilometers (13,000 miles per hour) per second. When the heat shield did all this, the spacecraft hit the ground at 400 meters per second (8,950 miles per hour). The parachute of curiosity can slow down, slow it down, but only 80 meters (179 miles per hour) per second. Killing the ground at that speed is not even alive for the robot.
On an airless world like the moon, the heat shield is not required, and parachutes do not do well to you. However, do not fear, since the 1960s, we have a technology for moon landing: take some rockets and cancel the speed of the craft and point them down.
The atmosphere makes things a little confusing on Mars, however. Along with carrying air as an additional factor, unexpected winds can add evenly unexpected horizontal velocity to the descending spacecraft. For this reason, less regional slopes are required in landing areas on Mars. Along with high horizontal winds, high slopes can be closer to the ground or closer to the ground, and the situation can either spell disaster.
So one Mars Lander needs three techniques to reach the surface: a summer shield, a supersonic deployment parachute, and retrorockets. In the mid-1970s, the Viking missions of Mars were prepared by a test-launch parachute on the suburban rocket to verify that they could rapidly flutter without any tilt. Since then all prosperous planetary planets (all of NASA) have trusted the parachute with Viking heritage. Recently, NASA worked on the new effort to develop recession technologies capable of enlarging the spacecraft in comparison to the Viking investigation – an effort that was not successful initially, resulting in a devastating cut Parachute happened (Recent tests have done better.)
Keeping this in mind, what do we know about the recent failure of Mars Landers? For two of the – Mars Polar Lander and Beagle 2 – We can only guess. Spacecraft could not transmit real-time telemetry data. Mars Polar Lander Failure taught NASA a valuable lesson: If we want to learn something from our failures, then we need to gather as much data as possible until the point of failure. Since the Mars planet at the end of 1999, the Polar Lander had crashed on the surface, each Mars Leader, except the Beagle 2 of ESA, has transmitted data to an orbiter, which, in the event of failure, will have a raw radio signal record for future analysis Have done
These days, there are many classes on Mars so that we can do better. In case of disaster, always an orbiter is listening and recording every last bit of radio signal from a lander. Moreover, usually there is a secondary orbiter that does not listen to the signal, but rather decodes it and gives information to the Earth in the form of a slow journey of light. This “bent-pipe” data transmission has given us a picture of adrenaline-flashy, real-time picture of Mars Landing endeavors.
When Insights Land, if this effort fails, it will fall into Mars Reconnaissance Orbiter to record telemetry for future dissection. In order to get real-time data for landing, Insight has brought two small spacingfirsting partners: Marco Cubatas, each is only three feet long. Mars cube A space shuttle is the first interplanetary cubes. If the craft succeeds, the world will get a real-time report on the insight’s landing, and small space robots will pave the way for the future, small, cheaper travel to Mars.
However, for now, all the eyes are on the Insight. NASA has successfully landed seven times on Mars, and before the end of the month, the space agency is trying to make it eight.
