BUSAN, South Korea — NASA has canceled a robot lunar rover project that might have looked for ice on the south pole of the moon, bringing up building delays and value overruns.
NASA introduced July 17 that it might finish building of the Volatiles Investigating Polar Exploration Rove (VIPER) project. The rover, to be despatched to the south polar area of moon on a industrial lander referred to as Griffin from Astrobotic Era, would have explored terrain together with completely shadowed areas to raised perceive the level and type of water ice there.
At a briefing to announce the cancellation, company officers stated prices of VIPER had grown via greater than 30%, triggering a termination overview via the company. NASA had showed VIPER in 2021 at a price of $433.5 million. Joel Kearns, deputy affiliate administrator for exploration in NASA’s Science Project Directorate, stated the most recent estimate was once $609.6 million, with a release estimated in September 2025.
“On this case, the projected final bills for VIPER would have ended in both having to cancel or disrupt many different missions in our Business Lunar Payload Services and products line,” stated Nicky Fox, NASA affiliate administrator for science. “Subsequently, we now have made the verdict to forgo this actual project.”
Kearns stated VIPER suffered from a sequence of provide chain problems that not on time deliveries of key, unspecified parts courting again to the pandemic. “The delays befell over and over again for a number of key parts,” he stated, with small incremental delays that have been more difficult for the project to devise round than a unmarried massive lengthen.
That difficult the development of the rover, which he described the scale of a small automobile this is constructed from the interior out. “Most of the parts that have been not on time have been in truth within the internal phase of VIPER, in order the parts have been not on time, it began forcing the VIPER crew to lengthen the meeting and lengthen the combination and preliminary checking out.”
The rover is now entire, however is handiest now beginning environmental checking out. Kearns stated the revised price and time table assumed that VIPER would get via that environmental checking out with none issues. “I can you inform you that usually, spacecraft building system-level environmental checking out does discover issues that do want to be corrected, which might take extra money and time.”
Canceling VIPER now will save NASA at least $84 million. That would develop, he stated, if VIPER’s release have been to slide past November 2025, which will require ready 9 to twelve months till the proper lighting fixtures prerequisites go back on the touchdown website within the polar area.
Kearns and Fox stated a lot of the science that VIPER would have carried out can be performed via different missions, together with landers and orbiters. The mobility that VIPER would have supplied, although, might not be to be had till NASA’s Lunar Terrain Car, a rover for crewed Artemis missions however which will also be teleoperated, is delivered past due this decade.
NASA plans to disassemble VIPER to reuse its tools and different parts. First, although, NASA will believe proposals from American corporations and world companions to fly VIPER on their very own without charge to the federal government. Proposals are because of NASA Aug. 1.
Revising Griffin’s project
Break away its personal building issues, VIPER confronted delays from Griffin, Astrobotic’s lander that might ship the rover to the moon beneath a CLPS activity order value $322 million. NASA stated Griffin was once now anticipated to be in a position for the project no previous than September 2025.
With VIPER canceled, NASA will retain the duty order for Griffin. The project will as an alternative grow to be a era demonstrator, sporting a mass simulator instead of the rover to check Griffin’s talent to land massive payloads.
Kearns stated NASA regarded as flying science payloads as an alternative, however because the lander was once designed for sporting a rover, it lacked payload lodging and functions like energy and communications the ones payload would wish.
“We imagine that if we have been to invite Astrobotic to make adjustments like that, it might additional lengthen their time table,” he stated of possible adjustments to deal with payloads. “It will result in extra price for the federal government. It will result in a lengthen of the demonstration of a a success south pole touchdown via the massive Griffin lander, which we’re very keen on seeing.”
Astrobotic can also be unfastened to fly their very own industrial payloads. John Thornton, leader government of Astrobotic, stated in an interview that the corporate is thinking about flying a check of its LunaGrid energy technology provider on Griffin. “We do wish to fly briefly however we additionally wish to make a project this is extra impactful than simply the lander itself.”
A VIPER-less Griffin would nonetheless land on the south polar area of the moon, he stated, despite the fact that no longer essentially on the similar website NASA decided on for VIPER. It’ll rely on any new payloads it indicators up for the lander, with the choice of going to a more secure touchdown website to scale back the danger for the project.
Each Kearns and Thornton stated that the company knowledgeable the corporate of the verdict very not too long ago, however weren’t extra explicit. One business supply stated NASA knowledgeable Astrobotic of the verdict only a day earlier than it was once publicly introduced.
“This has been without a doubt a 12 months of tumult and problem for Astrobotic as an organization,” he stated, a connection with the release in January of its first lunar lander, Peregrine, which suffered a propellant leak after release and may no longer strive a lunar touchdown. The VIPER cancellation is “without a doubt some other punch to the intestine right here, however we’ll roll with it.”
Kearns stated that NASA believed that Griffin would be capable of land protection at the moon, without or with VIPER on board, noting the paintings NASA funded the corporate to do to accomplish further propulsion components exams. “We do believe in them to head out and strive this touchdown, or we wouldn’t be proceeding to paintings with them.”
“I’m an everlasting optimist. You more or less must be within the area business,” Thornton stated. “I’m thinking about what we will flip this into.”
