NASA announced on Friday, June 24, 2022, that the Psyche asteroid mission, the agency’s first mission designed to study a metal-rich asteroid, will not make its planned 2022 launch attempt.
Due to the late delivery of the spacecraft’s flight software and testing equipment, NASA lacks sufficient time to complete the testing required ahead of its remaining launch period this year, which ends on October 11. The mission team needs additional time to ensure that the software will function properly in flight.
NASA selected Psyche in 2017 as part of the agency’s Discovery Program, a line of low-cost, competitive missions led by a single principal investigator. The agency is forming an independent assessment team to review the path forward for the project and for the Discovery Program.
“NASA takes the cost and schedule commitments of its projects and programs very seriously,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “We are exploring options for the mission in the context of the Discovery Program, and a decision on the path forward will be made in the coming months.”
The independent assessment team, typically made up of experts from government, academia, and industry, will review possible options for next steps, including estimated costs. Implications for the agency’s Discovery Program and planetary science portfolio also will be considered.
The spacecraft’s guidance navigation and flight software will control the orientation of the spacecraft as it flies through space and is used to point the spacecraft’s antenna toward Earth so that the spacecraft can send data and receive commands. It also provides trajectory information to the spacecraft’s solar electric propulsion system, which begins operations 70 days after launch.
As the mission team at NASA’s Jet Propulsion Laboratory in Southern California began testing the system, a compatibility issue was discovered with the software’s testbed simulators. In May, NASA shifted the mission’s targeted launch date from August 1 to no earlier than September 20 to accommodate the work needed. The issue with the testbeds has been identified and corrected; however, there is not enough time to complete a full checkout of the software for a launch this year.
“Flying to a distant metal-rich asteroid, using Mars for a gravity assist on the way there, takes incredible precision. We must get it right. Hundreds of people have put remarkable effort into Psyche during this pandemic, and the work will continue as the complex flight software is thoroughly tested and assessed,” said JPL Director Laurie Leshin. “The decision to delay the launch wasn’t easy, but it is the right one.”
The mission’s 2022 launch period, which ran from August 1 through October 11, would have allowed the spacecraft to arrive at the asteroid Psyche in 2026. There are possible launch periods in both 2023 and 2024, but the relative orbital positions of Psyche and Earth mean the spacecraft would not arrive at the asteroid until 2029 and 2030, respectively. The exact dates of these potential launch periods are yet to be determined.
“Our amazing team has overcome almost all of the incredible challenges of building a spacecraft during COVID,” said Psyche Principal Investigator Lindy Elkins-Tanton of Arizona State University (ASU), who leads the mission. “We have conquered numerous hardware and software challenges, and we’ve been stopped in the end by this one last problem. We just need a little more time and will get this one licked too. The team is ready to move forward, and I’m so grateful for their excellence.”
Total life-cycle mission costs for Psyche, including the rocket, are $985 million. Of that, $717 million has been spent to date. The estimated costs involved to support each of the full range of available mission options are currently being calculated.
Two ride-along projects were scheduled to launch on the same SpaceX Falcon Heavy rocket as Psyche, including NASA’s Janus mission to study twin binary asteroid systems, and the Deep Space Optical Communications technology demonstration to test high-data-rate laser communications that is integrated with the Psyche spacecraft. NASA is assessing options for both projects.
ASU leads the Psyche mission. JPL, which is managed for NASA by Caltech in Pasadena, California, is responsible for the mission’s overall management; system engineering; integration and test; and mission operations. Maxar is providing the high-power solar electric propulsion spacecraft chassis. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, is managing the launch.
[email protected]. Too important and to expensive to not be really careful !! Leave nothing to chance because as we all know ,if it can go wrong ,it will!!
Who was responsible for developing the software?
Why is this pseudo-scientific crap posted on a site dedicated to real science?
Week leadership. Just F*ing make it happen-in keeping with the proudest traditions of NASA
No Nasa could care less about its cost versus what NEEDS TO BE DONE. Nasa at this point serves not useful purpose except as related to earth satellite systems.
It is quite clear and has been for years, that nothing beyond the moon, as a practical matter will never have humans on it, A space ship operating for years, without any means of physical support from earth is just science non reality thinking. Not to mention having children on a long distance space ship project is nothing but cruel and unusual treatment, when they will know the very different life they would have had had they been born on earth. As would be taking you children with you on a long space journey. Private citizens can of course spend the money for no reality driven purpose. but using tax money of everyone, makes absolutely no sense at the this point just to satisfy some scientist curiosity.
See if Elon has the bandwidth to grab this bull by the horns and “get er done”. Too far into it to slow down or pull the plug. See an obstacle? If I may quote Jimi Hendrix….”well I stand up next to a mountain, chop it down, with the edge of my hand……” Elon, can you lend one of your talented hands sir?
Mission on schedule, sidelined by dominating lobbyist corporate entity that desires to reach Psyche first and claim its riches by redirecting it toward the Gulf of Mexico for a “gentle” splashdown and retrieval. Nothing to worry about. Trickle down asteroid economics. Don’t look up.
What a wildly sounding Psyche mission about a Psyche mission. How intriguing it would be to be part of with not knowing you were part of a space mission! Wow!
