Engineers Israeli company SpaceIL, who developed the lunar landing module “Genesis”, found the cause of the fall of the apparatus when the satellite of our planet on April 11. As it turned out, the main reason lay not in the engine module, as previously assumed, a software failure of the onboard computer of the apparatus after execution of “incorrect command”, which led to a “chain reaction” stated in the “Twitter” of the company.
“It seems that during landing the computer apparatus has received a wrong command that caused a kind of chain reaction. It also led to the shutdown of the main engine “Bereshit” and prevented us from re-enable it,” — said in a microblog SpaceIL.
It should be noted that the Israeli team managed to restart the engines module, which led to an increase in the rate of fall of the apparatus to 475 miles an hour, and he by this time was only 150 meters from the lunar surface. This led to the loss of the probe, as during this time a running main engine “Bereshit” just couldn’t brake it to a sufficiently low speed.
As pointed out by the engineers of the Israeli company, the preliminary results of the data analysis show that the crash was wearing a programmatic nature, not the hardware. In the operating system “Bereshit” had yet unnamed error that led it to freeze the system and disable the landing engines. The company intends to announce the final findings of the investigation of the incident in the coming weeks.
Despite the setback, the head of SpaceIL Morris Kahn has announced that it will allocate funds for the creation of the second version of “Bereshit” to make the first landing a private spacecraft on the lunar surface in the next 2-3 years. Their support also expressed by the Prime Minister of Israel Benjamin Netanyahu promised that tel Aviv will actively support the initiatives of SpaceIL including the launch of “Bereshit-2”, in the future. In addition, he did not rule out the possibility of Israel creating its own space programme.
It should be noted that this is not the first programming error of the spacecraft in history, which eventually led to his death. For example, a similar fate “Bereshit” shared a Japanese telescope “Hitomi”. Because of a critical software failure caused due to accidental typos and errors in the code, it exploded. At the time, for similar reasons to the same Mars fall modules”, Peparelli” and the Mars Climate Orbiter.
