It appears that the second engine burn to raise the orbit of Israel’s privately built lunar lander, Beresheet, did not happen as planned because of an unexpected computer reboot.
In a statement Tuesday morning, SpaceIL and Israel Aerospace Industries (IAI) engineers said they were investigating the malfunction, but said that other than a known problem with the navigation system’s star tracker, the Beresheet’s systems were all functioning properly.
The maneuver was scheduled to take place Monday night, as the spacecraft passed near the Earth in an area where the Ramat Gan-based SpaceIL ground crew would not be in direct communication with the craft.
During the pre-maneuver phase, the spacecraft computer reset unexpectedly, and the maneuver was automatically cancelled.
The question that immediately comes to mind: Did they purchase a space-hardened computer? Cosmic rays can wreck havoc on computer memory, causing just this type of unexpected reset, so computers in space need to be much better shielded than on Earth.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
