Cause of the first civilian lunar accident? Due to "manual operation"

According to the results of the badysis, the cause of the crash of Israeli civilian lunar explorer Bereshit, who did not land on the moon on November 11, could be caused by a "manual operation" on floor. The Israeli space company and the Israeli aerospace industry (IAI) said Wednesday that "the manual operation caused a series of reactions to the probe, which caused the shutdown of the main engine Bereshit" It was not activated. "

This statement followed a preliminary inquiry shortly after the failure of the Bereshaw landing. Space.com, a space agency, said: "It seems clear that the manual operation on the probe computer is the cause of the failure of the landing."

Space Day staff is studying the situation at Bereshit at Israel's aerospace headquarters during the launch of Berrett Feb. 22. A preliminary investigation into the cause of the failure of the lunar landing of Bereshit revealed the possibility that an attempt at manual ground operation is causing the accident. a motor problem in order to repair the device for measuring the inertia appeared for the first time on the Bereshit.

Beresht is the first Israeli lunar probe and the first lunar probe deprived of history. It was launched February 21 from the Kennedy Space Center at Cape Canaveral Air Force Base in Florida and traveled 6.5 million kilometers. However, the engine crashed and crashed about 15 km above the moon just before landing. It was the moment when the Space Day dream, which targeted the first civilian moon landing in Israel and the first to land on the sixth lunar landing, was a failure.

According to a statement released today by CEO Iso Antbis Space, the main problem of Bereshit was a malfunction of the Inertial Measurement Unit (IMU). The inertial measurement device is a device that collectively measures and calculates the speed, direction, gravity, and acceleration of the probe.

Choi Byeong-hyuk, a researcher at the Korea Institute for Aeronautical and Space Research, said: "When an inertial measurement system was working badly, Bereshito had landed on the ground and could have misjudged the situation at the time. That's when I got into the control, but it's likely to be a problem. "The inertial measurement device is important evidence to recognize the probe's landing situation, so it would be very difficult to solve the problem by manually adjusting the probe to the ground if an error occurred here.

However, as this statement is the result of a preliminary investigation, Space One has announced that it will continue its investigations to identify the event as a whole. NASA also plans to use the LRO (Recognition) reconnaissance satellite (LRO) to repeatedly take photos of the Bresset crash site to help identify the cause of the landing failure. Indeed, we can trace the situation according to the severity of beresite and traces on the surface of the moon.

The American Lunar Reconnaissance Satellite (LRO) launched in 2009 by NASA (National Aeronautics and Space Administration) allows for accurate imaging of the lunar surface with a 50 cm pixel .

Choi Ki-hyeok, researcher in charge of the project, said: "In the case of a lunar reconnaissance satellite circling a lunar orbit, it is possible to photograph a precise lunar surface with a 50 cm pixel." "We can use the laser altimeter (LOLA) to track the debris of Bereshit."

As moon reconnaissance satellites fire at the moon's surface about twice a month, the final results should be available in the coming weeks. Benjamin Netanyahu, after observing the failure of the Bereshit landing, said: "If we do not succeed, we will have to challenge again." Israel said it would try to land again on the moon in two years. "
