Video: Supersonic drone flies with revolutionary detonation engine

A supersonic drone that will be propelled by a revolutionary new engine has taken to the skies for the first time. When Venus Aerospace’s aircraft does go supersonic on a later date, it will be powered by a Rotating Detonation Rocket Engine (RDRE).

Supersonic drones may sound like something bleeding edge, but they’re surprisingly old hat as a basic concept. As far back as the early 1950s, the US Air Force was fielding remote-controlled supersonic jets for targets to test air defenses, as platforms for reconnaissance in dangerous areas, or as weapons armed with conventional or nuclear warheads.

However, the one thing they’ve all had in common over the past 75 years was a jet engine for propulsion to boost them past Mach 1. In recent years, advances in avionics, aerodynamics, and autonomous systems have allowed uncrewed aircraft to expand their roles, but at their heart, they were still jet propelled.

NASA selects three companies to advance Artemis lunar rover designs

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 Selects Companies to Advance Moon Mobility for Artemis Missions

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.”

Elon Musk reveals plan for next Starship mission

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.
