Moon Mountain Named After Melba Roy Mouton, NASA Mathematician

Award-winning NASA mathematician and computer programmer Melba Mouton is being honored with the naming of a mountain at the Moon’s South Pole. Mouton joined NASA in 1959, just a year after the space agency was established. She was the leader of a team that coded computer programs to calculate spacecraft trajectories and locations. Her contributions were instrumental to landing the first humans on the Moon.

She also led the group of "human computers," who tracked the Echo satellites. Roy and her team's computations helped produce the orbital element timetables by which millions could view the satellite from Earth as it passed overhead.

The towering lunar landmark now known as “Mons Mouton” stands at a height greater than 19,000 feet. The mountain was created over billions of years by lunar impacts. Huge craters lie around its base—some with cliff-like edges that descend into areas of permanent darkness. Mons Mouton is the future landing site of VIPER, our first robotic Moon rover. The rover will explore the Moon’s surface to help gain a better understanding of the origin of lunar water. Here are things to know:

Mons Mouton is a wide, relatively flat-topped mountain that stretches roughly 2,700 square miles

The mountain is the highest spot at the Moon’s South Pole and can be seen from Earth with a telescope

Our VIPER Moon rover will explore Mons Mouton over the course of its 100-day mission

VIPER will map potential resources which will help inform future landing sites under our Artemis program

The VIPER mission is managed by our Ames Research Center in California’s Silicon Valley. The approximately 1,000-pound rover will be delivered to the Moon by a commercial vendor as part of our Commercial Lunar Payload Services initiative, delivering science and technology payloads to and near the Moon.

We Found the Perfect Spot to Land our Moon Rover

After an extensive selection process, we chose the mountainous area west of Nobile Crater at the Moon’s South Pole as the landing site for our first-ever robotic Moon rover. The Volatiles Investigating Polar Exploration Rover, or VIPER, will explore the Moon’s surface and subsurface in search of water and other resources beginning in late 2023. Thanks to past missions, such as satellites orbiting the Moon or impacting its surface, we know there is ice at the Moon’s poles. But how much? And where did it come from? VIPER aims to answer these questions and more by venturing into shadowed craters and visiting other areas of scientific interest over its 100-day mission. The findings will inform future landing sites under the Artemis program and help pave the way toward establishing a long-term human presence on the Moon. Here are five things to know:

The landing site is located just outside the western rim of Nobile Crater at the Moon’s South Pole.

The region has suitable lighting and terrain for our solar-powered rover to navigate.

VIPER will travel up to 15 miles in search of water and other resources.

Its traverse will change depending on what it finds, but it could look like this.

Drivers on Earth will tell the rover where to explore during its 100-day mission.

The Rover Doctor is in: The Anatomy of a NASA Human Exploration Rover Challenge Rover

Exploration and inspiration collide head-on in our Human Exploration Rover Challenge held near Marshall Space Flight Center in Huntsville, Alabama, each April. The annual competition challenges student teams from around the world to design, build and drive a human-powered rover over a punishing half-mile course with tasks and obstacles similar to what our astronauts will likely have on missions to the Moon, Mars and beyond.

The anatomy of the rover is crucial to success. Take a look at a few of the vital systems your rover will need to survive the challenge!

The Chassis

A rover’s chassis is its skeleton and serves as the framework that all of the other rover systems attach to. The design of that skeleton incorporates many factors: How will your steering and braking work? Will your drivers sit beside each other, front-to-back or will they be offset? How high should they sit? How many wheels will your rover have? All of those decisions dictate the design of your rover’s chassis.

Wheels

Speaking of wheels, what will yours look like? The Rover Challenge course features slick surfaces, soft dunes, rocky craters and steep hills – meaning your custom-designed wheels must be capable of handling diverse landscapes, just as they would on the Moon and Mars. Carefully cut wood and cardboard, hammer-formed metal and even 3-D printed polymers have all traversed the course in past competitions.

Drivetrain

You’ve got your chassis design. Your wheels are good to go. Now you have to have a system to transfer the energy from your drivers to the wheels – the drivetrain. A good drivetrain will help ensure your rover crosses the finish line under the 8-minute time limit. Teams are encouraged to innovate and think outside the traditional bike chain-based systems that are often used and often fail. Exploration of the Moon and Mars will require new, robust designs to explore their surfaces. New ratchet systems and geared drivetrains explored the Rover Challenge course in 2019.

Colors and Gear

Every good rover needs a cool look. Whether you paint it your school colors, fly your country’s flag or decorate it to support those fighting cancer (Lima High School, above, was inspired by those fighting cancer), your rover and your uniform help tell your story to all those watching and cheering you on. Have fun with it!

Are you ready to conquer the Rover Challenge course? Join us in Huntsville this spring! Rover Challenge registration is open until January 16, 2020 for teams based in the United States.

If building rovers isn’t your space jam, we have other Artemis Challenges that allow you to be a part of the NASA team – check them out here.

Want to learn about our Artemis program that will land the first woman and next man on the Moon by 2024? Go here to read about how NASA, academia and industry and international partners will use innovative technologies to explore more of the lunar surface than ever before. Through collaborations with our commercial, international and academic partners, we will establish sustainable lunar exploration by 2028, using what we learn to take astronauts to Mars. 

The students competing in our Human Exploration Rover Challenge are paramount to that exploration and will play a vital role in helping NASA and all of humanity explore space like we’ve never done before!
