An order to correct a malfunction in one of the Beresheet spacecraft's inertial measurement units resulted in a series of events that shut off the main engine during landing. This resulted in a preliminary study by SpaceIL.

During a Comprehensive Investigation Ido Anteby, CEO of SpaceIL, said Wednesday that the failure of the Inertial Measurement Unit (IMU) during the landing maneuver was the first failure during the seven-week lunar mission.
A sequence of events triggered by an order from the SpaceIL control room shut down the main engine of the spacecraft and prevented proper engine activation, Anteby said, making a moon landing inevitable.

The disruption occurred only a few minutes before Beresheet, developed by SpaceIL and Israel Aerospace Industries, was to make a historic landing – a feat that has so far reached only the US, Russia (then the USSR) and China – after 6.5 million km had. Journey since she was fired aboard a SpaceX missile from Cape Canaveral, Florida on February 22nd.

"There has been no such incident since the mission began," Anteby told reporters. "After this was done, an Activation Order was sent to [the IMU]causing a chain of events where the main engine was stopped and could not return to continuous operation."

While the spacecraft repeatedly tried to restart the engine, the attempts were unsuccessful.

"Immediately after the incident, we started our investigation. This is part of our learning culture that leads to conclusions and transparency, "said Anteby.

" We have completed the first phase of the investigation, focusing only on understanding the facts and the order of events. We tried to understand what happened, based on the telemetry of the spacecraft. "

Only after a comprehensive investigation, Anteby says, will the engineers know if something else could have happened and if the team was prepared for such a disruption. All that understanding, he added, will contribute to the success of a future mission.

"I'm proud of the team of SpaceIL engineers for their wonderful work and dedication," said SpaceIL Chairman Morris Kahn.

an integral part of a complex and groundbreaking project. Now it is important to learn from our mistakes the best possible lessons and to continue bravely. That's the message we want to convey to people in Israel and around the world. This is the spirit of the Beresheet project.

Kahn, the main donor behind the project, has already held several meetings with the team behind the spaceship to schedule Beresheet 2, a second moon landing mission.

The original mission budget amounted to approximately 350 million NIS (98 million US dollars), which are almost entirely financed by private donors and a fraction of the emissions financed by the mission cost the governments of the three countries that successfully the moon achieved.
