Russia says it is aware of what induced the failure of its first moon shot in almost 50 years.
The Luna-25 lander — the primary Soviet or Russian moon probe since Luna-24 in 1976 — crashed into the moon on Aug. 19, throughout a maneuver designed to arrange a landing try close to the lunar south pole two days later.
Officers with Roscosmos, Russia’s federal house company, introduced a proximate trigger for the mishap shortly thereafter: Luna-25’s engines fired for 127 seconds throughout the burn as a substitute of the scheduled 84.
Now, a possible final trigger has become visible. It seems that an onboard management unit failed to show the engines off as a result of it wasn’t receiving the required information from one in every of Luna-25’s accelerometers, gadgets used to detect and measure movement. The accelerometer unit was not turned on, “as a result of potential entry into one information array of instructions with totally different priorities for his or her execution by the gadget,” Roscosmos wrote in a Telegram submit on Tuesday (Oct. 3). (The submit is in Russian; translation by Google.)
“This didn’t permit, when issuing a corrective pulse, to report the second the required velocity was reached and to well timed flip off the spacecraft propulsion system, because of which its shutdown occurred in response to a short lived setting,” the submit added.

Luna-25 was designed to restart Russia’s proud lunar exploration program, and the failure will not change that imaginative and prescient, in response to Roscosmos officers and Russian President Vladimir Putin.
The nation has mentioned it goals to launch three follow-on missions — Luna-26, Luna-27 and Luna-28 — in 2027, 2028 and no sooner than 2030, respectively. However these timelines might be accelerated within the wake of the Luna-25 crash, Roscosmos chief Yuri Borisov mentioned on the 2023 Worldwide Astronautical Congress, which is being held this week in Azerbaijan.
“Nobody goes to fold their arms, and we’re decided to proceed the lunar program. Furthermore, we’re contemplating the potential for shifting the Luna-26 and Luna-27 missions to the left with a purpose to get the outcomes we want as rapidly as potential,” Borisov mentioned on the convention, Roscosmos wrote in one other Telegram submit (additionally in Russian; translation by Google).
Luna-25 aimed to be the primary mission ever to land within the moon’s south polar area, which is considered wealthy in water ice.
The Russian probe’s failure allowed India’s Chandrayaan-3 mission to assert that title. Chandrayaan-3 put a lander-rover duo down close to the south pole on Aug. 23, simply 4 days after Luna-25’s crash.
Chandrayaan-3’s success made India simply the fourth nation ever to soft-land a spacecraft on the moon, after the Soviet Union, the USA and China.
