The VIPER rover was meant to be a key scouting mission ahead of NASA’s Artemis program, collecting crucial information about water-ice reserves at the lunar south pole.

To the shock of the lunar science community, on July 17, NASA cancelled the much-anticipated Volatiles Investigating Polar Exploration Rover (VIPER) mission, which was expected to prospect for water ice on the Moon — a critical resource for future explorers.

VIPER was one of the highest profile missions in NASA’s ongoing Commercial Lunar Payload Services (CLPS) program, which that is sending robotic missions to the Moon in support of future Artemis crews. Artemis targets landing near the lunar south pole, where the shallow angle of the Sun means many craters lie in permanent shadow. Scientists know that these craters contain water ice, which could be used as drinking water for astronauts and as a resource for rocket fuel and energy production. But we don’t know how much ice is there, nor how easy it will be to extract. VIPER’s mission was to answer those questions — and its cancellation deprives the Artemis program of critical data.

Equally shocking to the science community is that $450 million has already been spent designing and building VIPER and its suite of instruments. The completed VIPER only needed to pass its environmental tests to ensure it could survive in the Moon’s incredibly harsh, perpetually shadowed polar regions. The rover and the Astrobiotics Griffin lunar lander that was to deposit VIPER near the south pole were scheduled to launch in September 2025 aboard a SpaceX Falcon Heavy rocket.

NASA has said it is open to handing VIPER over to another organization to fly it to the Moon — if it comes at no additional cost to NASA. If no takers emerge, current plans call for the dismantling of VIPER and cannibalizing its instruments for possible use in future missions.

NASA’s explanation for VIPER’s cancellation is that COVID-induced supply chain issues with both the rover and its Griffin lander escalated mission costs and have delayed its anticipated launch by two years. By cancelling the project, after already spending nearly half a billion dollars, NASA says it will save $84 million. At the same time, NASA will pay Astrobiotics $323 million to complete the Griffin lander and fly it to the Moon without VIPER. At this time, plans call for landing a “mass simulator,” or a dead weight, that will return no science data about the Moon.

New research from the group of MIT Professor Brett McGuire has revealed the presence of a previously unknown molecule in space. The team's open-access paper, "Rotational Spectrum and First Interstellar Detection of 2-Methoxyethanol Using ALMA Observations of NGC 6334I," was published in the April 12 issue of The Astrophysical Journal Letters.

Zachary T.P. Fried, a graduate student in the McGuire group and the lead author of the publication worked to assemble a puzzle comprised of pieces collected from across the globe, extending beyond MIT to France, Florida, Virginia, and Copenhagen, to achieve this exciting discovery.

"Our group tries to understand what molecules are present in regions of space where stars and solar systems will eventually take shape," explains Fried. "This allows us to piece together how chemistry evolves alongside the process of star and planet formation. We do this by looking at the rotational spectra of molecules, the unique patterns of light they give off as they tumble end-over-end in space.

"These patterns are fingerprints (barcodes) for molecules. To detect new molecules in space, we first must have an idea of what molecule we want to look for, then we can record its spectrum in the lab here on Earth, and then finally we look for that spectrum in space using telescopes."
