Israeli hopes dashed after spacecraft crashes on Moon
State-owned IAI and nonprofit space venture SpaceIL’s unmanned robotic lander suffers engine failure during final descent
Yehud — Israeli spacecraft Beresheet crashed onto the moon on Thursday after a series of technical failures during its final descent, shattering hopes of a historic controlled landing on the lunar surface.
The unmanned robotic lander suffered periodic engine and communications failures during the landing sequence, which lasted about 21 minutes, the support team said.
Beresheet, whose name is Hebrew for the biblical phrase “In the beginning”, had travelled through space for seven weeks in a series of expanding orbits around Earth before crossing into the Moon’s gravity last week.
The final manoeuvre on Wednesday brought it into a tight elliptical orbit around the Moon, about 15km from the surface at its closest. From there it was a short, nail-biting and ultimately disappointing conclusion.
“It seems that a failure in our inertial measurements unit caused a chain of events in the spacecraft avionics which cut off the engines and caused us to lose the mission,” said Opher Doron, GM of the space division at Israel Aerospace Industries.
So far, only three nations have succeeded in carrying out a soft, or controlled, landing on the lunar surface: the US, the Soviet Union and China.
Beresheet would have been the first craft to land on the moon that was not the product of a government programme. It was built by state-owned IAI and Israeli nonprofit space venture SpaceIL with $100m funded almost entirely by private donors.
Still, the spacecraft achieved some milestones.
“It is by far the smallest, cheapest spacecraft ever to get to the moon,” said Doron. “It’s been an amazing journey, I hope we get a chance for another one.”
Shaped like a round table with four carbon-fibre legs, Beresheet stood about 1.5m tall. It blasted off from Florida’s Cape Canaveral on February 21 on a SpaceX Falcon 9 rocket and entered Earth’s orbit about 34 minutes after launch.
Its circuitous flight path was about 6.5-million kilometres. A direct route from the Earth to the moon covers about 240,000km.
