Wednesday Software fails – Indian Lunar Radar Crash

New details emerge about failed lunar landings

In a written response to questions Nov. 20 to the Lok Sabha, the lower house of India’s Parliament, Jitendra Singh, minister of state for the Department of Space, said that the Vikram lander “hard landed” on the moon Sept. 6 because of a problem with the lander’s braking thrusters.

“As result, all accumulated [software] updates that were stored on a volatile memory (SRAM) were eliminated during reboot,” the paper stated. “Therefore, the computer did not contain all the essential changes implemented during the flight, which made autonomous recovery impossible.”

Among the changes recommended in the paper were to allow full updates of the lander’s software during flight, and storing that software in non-volatile memory that is not wiped during a computer reboot.

“The big thing with us is teaming with the Israelis, with all of the successes they did have on Beresheet and fixing the problems that had,” Ferring said. “Taking the history, taking the lessons learned, building from that and doing better the next time.”


Failure may look bad from the outset but we must ask ourselves “What have we learned from this?”. If not for the many failures that humanity has experienced, would our technology be this advanced? Another example is the space race of the 20th century with multiple disasters talked about in this articleby history.co.uk

This is not an example of failure but Instagram started very simply where you can like and comment on photos. Now you can see other people’s stories, have a collection of photos, custom stickers for hashtags. Nothing starts perfect but we can always make incremental improvements.


Happy Testing!
