NASA inspector general asks Congress for Europa Clipper launch flexibility

WASHINGTON — NASA’s inspector basic says the company might save practically $1 billion if Congress provides it the flexibility to decide on the very best launch car for a mission to Jupiter’s moon Europa, moderately than mandating the usage of the Area Launch System.

In an Aug. 27 letter to the chairs and rating members of each the total Senate Appropriations Committee and its commerce, justice and science subcommittee, NASA Inspector Basic Paul Martin stated that language in previous appropriations payments will delay the launch of the Europa Clipper mission and add to its price.

“NASA’s renewed concentrate on returning people to the Moon on an accelerated timetable signifies that an SLS is not going to be accessible to launch the Clipper mission to Europa earlier than 2025 on the earliest,” he wrote within the conclusion of the seven-page letter. The fiscal 12 months 2019 appropriations invoice required that the mission launch by 2023 on an SLS.

“[W]e urge Congress to contemplate eradicating the requirement that NASA launch the Europa Clipper on an SLS and permit the Company to resolve whether or not to make use of an SLS or a industrial car based mostly on price, schedule, car availability, and impression on science necessities,” he added.

The letter is a follow-up to an audit of the Europa Clipper program that the Workplace of Inspector Basic revealed in Might. That report warned of price and schedule issues, together with the conclusion that an SLS wouldn’t be accessible for a 2023 launch due to manufacturing timelines and task of the primary two SLS autos for Artemis missions.

Since that audit, Europa Clipper handed a evaluate referred to as Key Resolution Level C, setting price and schedule baselines for the mission. Martin said in his letter that, whereas the spacecraft could possibly be prepared for launch in 2023, NASA established a 2025 launch date because the “Company Baseline Dedication” for the mission due to the requirement to make use of the SLS and the dearth of a car accessible for the mission earlier than 2025.

That strategy would require — assuming the spacecraft is accomplished in 2023 as projected — inserting Europa Clipper into storage for 2 years, at an estimated price of $3 million to $5 million monthly. Martin said within the letter that, on the latest evaluate, NASA allotted $250 million in reserves “to cowl storage, personnel, and different related launch delay prices.”

Launching in 2023 would eradicate the necessity for these reserves, saving $250 million from the estimated whole price of $4.25 billion established at that evaluate. Martin famous in his letter that NASA estimates utilizing a industrial launch car — both a United Launch Alliance Delta 4 Heavy or SpaceX Falcon Heavy — might save a further $700 million over an SLS launch. Nonetheless, the audit revealed in Might concluded that financial savings could possibly be lower than $300 million when accounting for the longer journey time, and thus operations prices, of launching Europa Clipper on a Delta 4 Heavy or Falcon Heavy.

“Congress might scale back dangers to each the Europa mission and Artemis program whereas doubtlessly saving taxpayers as much as $1 billion by offering NASA the pliability in forthcoming fiscal 12 months (FY) 2020 appropriations laws to find out probably the most price efficient and well timed car to launch the Europa Clipper mission in 2023 or at any time when the satellite tv for pc is accomplished,” Martin wrote.

A choice, he added, must be made “within the subsequent few months” in order that NASA has time to obtain a industrial launch car in time for a 2023 launch. An added complication is that ULA is planning to section out the Delta 4 Heavy round that point, with the final of 5 missions on its remaining manifest slated to launch in 2023.

The letter was despatched to Senate appropriators since they’re nonetheless creating their fiscal 12 months 2020 spending payments. The Home handed its model of a spending invoice for NASA in June, retaining the language from the 2019 invoice that requires Europa Clipper to launch on SLS in 2023.

The Senate has, previously, been much less supportive of Europa Clipper or a follow-on lander mission than the Home, not providing vital funding will increase or necessities for launching the mission on SLS by a particular date. The Home’s previous assist for the mission was linked to former Rep. John Culberson (R-Texas), who chaired the appropriations subcommittee that funded NASA and was a powerful advocate for exploration of Europa. Culberson misplaced his bid for re-election final November.
