NASA and DARPA will test nuclear thermal engines for crewed missions to Mars – Engadget

NASA is going back to an old idea as it tries to get humans to Mars. It is teaming up with the Defense Advanced Research Projects Agency (DARPA) to test a nuclear thermal rocket engine in space with the aim of using the technology for crewed missions to the red planet. The agencies hope to “demonstrate advanced nuclear thermal propulsion technology as soon as 2027,” NASA administrator Bill Nelson said. “With the help of this new technology, astronauts could journey to and from deep space faster than ever — a major capability to prepare for crewed missions to Mars.”

Under the Demonstration Rocket for Agile Cislunar Operations (DRACO) program, NASA’s Space Technology Mission Directorate will take the lead on technical development of the engine, which will be integrated with an experimental spacecraft from DARPA. NASA says that nuclear thermal propulsion (NTP) could allow spacecraft to travel faster, which could reduce the volume of supplies needed to carry out a long mission. An NTD engine could also free up space for more science equipment and extra power for instrumentation and communication.

As far back as the 1940s, scientists started speculating about the possibility of using nuclear energy to power spaceflight. The US conducted ground experiments on that front starting in the ’50s. Budget cutbacks and changing priorities (such as a focus on the Space Shuttle program) led to NASA abandoning the project at the end of 1972 before it carried out any test flights.

There are, of course, risks involved with NTP engines, such as the possible dispersal of radioactive material in the environment should a failure occur in the atmosphere or orbit. Nevertheless, NASA says the faster transit times that NTP engines can enable could lower the risk to astronauts — they could reduce travel times to Mars by up to a quarter. Nuclear thermal rockets could be at least three times more efficient than conventional chemical propulsion methods.

NASA is also looking into nuclear energy to power related space exploration efforts. In 2018, it carried out tests of a portable nuclear reactor as part of efforts to develop a system capable of powering a habitat on Mars. Last year, NASA and the Department of Energy selected three contractors to design a fission surface power system that it can test on the Moon. DARPA and the Defense Department have worked on other NTP engine projects over the last few years.

Meanwhile, the US has just approved a small modular nuclear design for the first time. As Gizmodo reports, the design allows for a nuclear facility that’s around a third the size of a standard reactor. Each module is capable of producing around 50 megawatts of power. The design, from a company called NuScale, could lower the cost and complexity of building nuclear power plants.

Red Bull set to announce Ford engine partnership deal with US car giant – BBC

Honda-powered Red Bull won both the drivers’ and constructors’ championships in 2022

Red Bull are poised to announce an engine partnership deal with US car giant Ford.

Ford will join forces with the team from 2026, part-funding the engine Red Bull are designing for the new regulations to be introduced that year.

The agreement is expected to be officially unveiled at Red Bull’s 2023 season launch in New York on Friday.

Ford set to announce F1 return with Red Bull engine deal – The Race

Red Bull and Ford are set to announce they will work together on a Formula 1 engine for 2026.

The widely rumoured collaboration will be announced on Friday, when Red Bull is set to reveal the livery for its 2023 car the RB19 at an event in New York.

Though not confirmed by either party, the news of a tie-up between Ford and the newly created Red Bull Powertrains engine division was mistakenly leaked in Italian media and is understood to be correct.

Ford has been interested in a potential F1 programme for several months, based around the 2026 engine regulations – which feature “100% sustainable fuels”, according to F1, and an increase in the electrical …….
