Artemis V Astronauts Will be Driving on the Moon

In the summer of ’69, Apollo 11 delivered humans to the surface of the Moon for the first time. Neil Armstrong and Buzz Aldrin spent just over two hours exploring the area near their landing site on foot. Only during Apollo 15, 16, and 17 did astronauts have a vehicle to move around in.

Artemis astronauts on the Moon will have access to a vehicle right away, and NASA is starting to test a prototype.

Momentum is building behind NASA’s Artemis program despite some setbacks. Artemis astronauts will explore the Moon far more thoroughly than the Apollo astronauts did, and technology is behind the improvement. Surface mobility is a key piece of Artemis. In April of 2024, NASA selected three vendors as part of their Lunar Terrain Vehicle Services contract.

NASA engineers at the Johnson Space Center are designing an unpressurized rover prototype known as the Ground Test Unit. It’s a human-rated, unpressurized LTV (Lunar Terrain Vehicle). The unit is being designed and built as a platform to evaluate rover designs being developed by three private companies: Intuitive Machines, Lunar Outpost, and Venturi Astrolab.

Intuitive Machines is known for its IM-1 mission with its Nova-C Lander. They were the first private company to land a spacecraft on the Moon.

Lunar Outpost is known for its Mobile Autonomous Prospecting Platform (MAPP) rover (MAPP) rover. MAPP will be used on Intuitive Machines’ IM-2 and IM-3 missions and will demonstrate aspects of In-Situ Resource Utilization.

Venturi Astrolab is known for developing hyper-deformable wheels and batteries for lunar rovers. They’re also developing their FLEX rover, a larger vehicle designed to be modular to meet different objectives.

The LTV will be used to test the technologies these three companies develop. It’ll be used to evaluate crew compartment design, rover maintenance, science payload, and many other aspects of their rovers.

“The Ground Test Unit will help NASA teams on the ground, test and understand all aspects of rover operations on the lunar surface ahead of Artemis missions,” said Jeff Somers, engineering lead for the Ground Test Unit. “The GTU allows NASA to be a smart buyer, so we are able to test and evaluate rover operations while we work with the LTVS contractors and their hardware.”

NASA has some requirements that the three selected companies need to meet. The rover must support two crew members and be able to be operated remotely. It can use multiple control concepts, such as supervised autonomy, different drive modes, and self-levelling.

NASA used its 'Moon Buggy' or Lunar Roving Vehicle (LRV) on Apollo 15, 16, and 17 in 1971 and 1972. It could carry 440 kg, including two astronauts, and had a top speed of 18 km/h. Though it provided range and mobility, it never travelled further than walking distance from the landers in case of breakdown.

By supplying the Ground Test Unit, NASA is making it easier to test the designs from the three companies. It also helps build private sector capacity by enabling testing and iterative design without the separate companies needing to spend money on a GTU. Ground testing also allows for a safer testing environment.

When Apollo 11 reached the Moon, it was a civilization-defining moment. There was no reason to explore beyond the landing site since it was as unexplored as the rest of the Moon. But things are much different now.

Thanks to other missions and satellites that orbit the Moon, we have an almost encyclopedic knowledge of our natural satellite compared to the Apollo days. We know what questions we want answered, where we can do the best science, and where useful resources like water ice is. The idea behind Artemis is to go to the Moon and create an infrastructure that will allow us to maintain a presence there.

The Artemis lunar missions will rely on mobility to meet their goals. The LTV will be critical to Artemis’ success by allowing each mission to explore and develop a larger area. NASA intends to use the new rovers starting in Artemis V, which will launch no sooner than 2030.

More Data and Machine Learning has Kicked SETI Into High Gear

For over sixty years, astronomers and astrophysicists have been engaged in the Search for Extraterrestrial Intelligence (SETI). This consists of listening to other star systems for signs of technological activity (or “technosignatures), such as radio transmissions. This first attempt was in 1960, known as Project Ozma, where famed SETI researcher Dr. Frank Drake (father of the Drake Equation) and his colleagues used the Robert C. Byrd Green Bank Telescope in West Virginia to conduct a radio survey of Tau Ceti and Epsilon Eridani. Since then, the vast majority of SETI surveys have similarly looked for narrowband radio signals since they are very good at propagating through interstellar space. However, the biggest challenge has always been how to filter out radio transmissions on Earth – aka. radio frequency interference (RFI). In a recent study, an international team led by the Dunlap Institute for Astronomy and Astrophysics (DIAA) applied a new deep-learning algorithm to data collecte...

The First Close-Up Picture of Star Outside the Milky Way

Like a performer preparing for their big finale, a distant star is shedding its outer layers and preparing to explode as a supernova. Astronomers have been observing the huge star, named WOH G64, since its discovery in the 1970s. It’s one of the largest known stars, and also one of the most luminous and massive red supergiants (RSGs). The star is surrounded by an envelope of expelled star-stuff, which could indicate it’s getting ready to explode. WOH G64 isn’t in the Milky Way; it’s in the Large Magellanic Cloud (LMC), the Milky Way’s largest satellite galaxy. Getting these detailed image is quite a feat for the ESO’s Very Large Telescope Interferometer. It’s also quite an accomplishment for the team of scientists behind the image. They’ve published their images and the results of their observations of the star in the journal Astronomy and Astrophysics. Their research is titled “ Imaging the innermost circumstellar environment of the red supergiant WOH G64 in the Large Magellanic ...

Planetary Surfaces: Why study them? Can they help us find life elsewhere?

Universe Today recently explored the importance of studying impact craters and what they can teach us about finding life beyond Earth. Impact craters are considered one of the many surface processes—others include volcanism, weathering, erosion, and plate tectonics—that shape surfaces on numerous planetary bodies, with all of them simultaneously occurring on Earth. Here, we will explore how and why planetary scientists study planetary surfaces, the challenges faced when studying other planetary surfaces, what planetary surfaces can teach us about finding life, and how upcoming students can pursue studying planetary surfaces, as well. So, why is it so important to study planetary surfaces throughout the solar system? “Planetary surfaces record the history of the Solar System, a history that’s almost entirely lost to us here on Earth,” Dr. Paul Byrne, who is an Associate Professor of Earth, Environmental, and Planetary Sciences at Washington University in St. Louis, tells  Uni...
