CAMBRIDGE, Mass. — NASA has selected three companies to work on lunar rover concepts that would be offered as a service for Artemis lunar landings and scientific activities.

NASA announced April 3 it picked teams led by Intuitive Machines, Lunar Outpost and Venturi Astrolab for its Lunar Terrain Vehicle (LTV) Services contract. The contract covers work to design and develop rovers that would be used by astronauts on Artemis missions starting with Artemis 5 at the end of the decade. The rovers would be provided by the companies to NASA as a service, in much the same way the agency is procuring spacesuits and lunar landers.

While the primary purpose of the LTV will be to transport astronauts across the lunar surface, NASA expects to also teleoperate the rover, allowing it to perform scientific investigations when astronauts are not present. “Think of a hybrid of the Apollo-style lunar rover that was driven by our astronauts and an uncrewed mobile science platform,” said Vanessa Wyche, director of NASA’s Johnson Space Center, at a briefing to announce the contract selections.

NASA has selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab to advance capabilities for a lunar terrain vehicle (LTV) that Artemis astronauts will use to travel around the lunar surface, conducting scientific research during the agency’s Artemis campaign at the Moon and preparing for human missions to Mars.

The awards leverage NASA’s expertise in developing and operating rovers to build commercial capabilities that support scientific discovery and long-term human exploration on the Moon. NASA intends to begin using the LTV for crewed operations during Artemis V.

“We look forward to the development of the Artemis generation lunar exploration vehicle to help us advance what we learn at the Moon,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “This vehicle will greatly increase our astronauts’ ability to explore and conduct science on the lunar surface while also serving as a science platform between crewed missions.”

April’s space watch list includes a Chinese space station mission and the test flight of a new Russian rocket.

Andreas Mogensen was impressed by how smooth a landing it was.

The first European Space Agency (ESA) astronaut (and first non-American) to serve as a pilot on a U.S. commercial crew spacecraft, Mogensen and his SpaceX Crew-7 crewmates returned to Earth after a 197-day stay aboard the International Space Station (ISS) on March 12.

Two SpaceX Falcon 9 rockets could take to the skies over Florida in back-to-back Saturday evening launches.

The static fire test comes less than two weeks after the last Starship mission, which saw the rocket reach orbital velocity for the first time before breaking up upon reentry to Earth’s atmosphere.

Gwynne Shotwell, SpaceX’s chief operating officer, said last week that the next launch attempt could take place in the “beginning part of May”, though no payload will be onboard.

The fourth major flight test of the fully stacked Starship rocket system will instead aim to resolve the issues that arose during the last mission.

An international team of researchers from Queen Mary University of London, the University of Oxford, Lancaster University, and the University of Waterloo have developed a new single-molecule transistor that uses quantum interference to control the flow of electrons. The transistor, which is described in a paper published in the Nature Nanotechnology (“Quantum interference enhances the performance of single-molecule transistors”), opens new possibilities for using quantum effects in electronic devices.

Transistor are the basic building blocks of modern electronics. They are used to amplify and switch electrical signals, and they are essential for everything from smartphones to spaceships. However, the traditional method of making transistors, which involves etching silicon into tiny channels, is reaching its limits.

As transistors get smaller, they become increasingly inefficient and susceptible to errors, as electrons can leak through the device even when it is supposed to be switched off, by a process known as quantum tunnelling. Researchers are exploring new types of switching mechanisms that can be used with different materials to remove this effect.
