NASA is Looking for a Commercial Partner to Save VIPER

Space exploration has led the world in that wonderful human ability to co-operate, alas history shows we don’t do it quite as much as we should! Recently NASA has put a request out to the wider community for ideas for their VIPER rover which was designed for lunar exploration. The exact purpose of VIPER was to hunt for volatile minerals in the polar regions of the Moon. The big question, will NASA get any takers?

NASA Stops Work on VIPER Moon Rover, Citing Cost and Schedule Issues

NASA says it intends to discontinue development of its VIPER moon rover, due to cost increases and schedule delays — but the agency is also pointing to other opportunities for robotic exploration of the lunar south polar region.

This Moon Rover Wheel Could be 3D Printed on the Moon

When you think about sending missions to the Moon, every single gram counts on launch day. Therefore, it makes sense to live off the land when you arrive with in-situ resource utilization. For example, what if you could fly a rover without wheels and 3D print them out of lunar regolith when you get there?

It just might happen.

Researchers used a 3D printer to build the same design for a wheel that will be part of the upcoming NASA VIPER rover. It was done using additive manufacturing (another word for 3D printing), melting metal powder and laying down and bonding a large number of successive thin layers of materials into the designed shape.

NASA's VIPER Rover's First Moments on the Moon Might Be its Most Terrifying

NASA is building its first-ever robotic lunar rover. Named VIPER (Volatiles Investigating Polar Exploration Rover), the rover is set for launch in late 2024. But the terrain it will find when it reaches the Moon is impossible to predict. A series of tests carried out this spring are helping engineers understand the rover’s limits, and will ensure that VIPER can disembark from its lander even on extremely uneven terrain.

One Day Astronauts Will Be Breathing Oxygen Made From Rocks

When there’s a permanent base on the Moon, astronauts will need a way to replenish their oxygen supply. Fortunately, there’s an almost infinite amount of oxygen in the surrounding regolith, locked up the rocks and soil. The key would be to figure out a cost-effective way to extract it.

Now, NASA has demonstrated that they can harvest oxygen from the lunar regolith, even in the vacuum conditions of space. They used a device called a carbothermal reactor to successfully extract oxygen from a simulated lunar regolith, while also simulating the heat that would be produced by a solar energy concentrator.

Engineers are Testing how VIPER can Handle the Gnarliest Lunar Terrain

NASA’s getting ready to send a VIPER to the Moon. Not the popular sports car but a rugged vehicle that can handle whatever the lunar surface can throw at it. The Volatiles Investigating Polar Exploration Rover (VIPER) was put through its paces recently at the Glenn Research Center in Cleveland. The prototype drove up test slopes and clambered over boulders and craters. It also made its way through a simulated quicksand type of soil in a “sink tank”. It passed with flying colors, and showed engineers how it will handle similar conditions on the Moon.

NASA’s VIPER Rover Will Hunt for Water Near Nobile Crater at Moon’s South Pole

The region includes permanently shadowed areas where subsurface water ice could persist, as well as sunlit areas that would make it possible to power the VIPER rover. (NASA Graphic)

NASA says its VIPER rover will head for the western edge of Nobile Crater near the moon’s south pole in 2023, targeting a region where shadowed craters are cold enough for water ice to exist, but where enough of the sun’s rays reach to keep the solar-powered robot going.

Today’s announcement provides a focus for a mission that’s meant to blaze a trail for Artemis astronauts who are scheduled to land on the lunar surface by as early as 2024, and for a sustainable lunar settlement that could take shape by the end of the decade.

“Once it’s on the surface, it will search for ice and other resources on and below the lunar surface that could one day be used and harvested for long-term human exploration of the moon,” Lori Glaze, director of the planetary science division at NASA’s Science Mission Directorate, said during a teleconference.

NASA is Planning to Build a Lunar Rover With a 1-Meter Drill to Search for Water Ice

Meet VIPER, NASA’s new lunar rover, equipped with a drill to probe the Moon’s surface and look for water ice. VIPER, or Volatiles Investigating Polar Exploration Rover, will carry a one-meter drill and will use it to map out water resources at the Moon’s south pole. It’s scheduled to be on the lunar surface by December 2023, one year later than it’s initial date.
