A science instrument on the James Webb Space Telescope (JWST) has been switched off and on again by NASA engineers after the spacecraft was struck by galactic rays, according to the space agency.

A blog post reveals that on Jan. 15 the telescope’s Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument was impacted by high-energy radiation from outside our solar system, disrupting its communications equipment.

NIRISS is crucial to JWST because it can analyze the atmospheres of distant exoplanets. So far it’s helped find carbon dioxide in the atmosphere of WASP-39b, a hot gas-giant orbiting a Sun-like star about 700 light-years from Earth.

Elon Musk lost his claim as having the most powerful space-worthy rocket when NASA blasted its own mega rocket to the moon in November.

But the SpaceX founder could win back the title with his company’s next big project. Starship, SpaceX’s skyscraping rocket and spacecraft, will launch on its first mission soon. During the test flight, the colossal booster will separate about three minutes after liftoff and land in the Gulf of Mexico, according to federal filings (Opens in a new window). The ship will fly in space around Earth at an altitude of over 150 miles, then splash down off the Hawaiian coast (Opens in a new window).

This will be a crucial demonstration of hardware NASA is depending on to get humans back on the moon in the next few years. And, if successful, it’ll mean Musk is one small step closer to realizing his personal dream of building a city on Mars.

Last year, space fans witnessed the long-awaited first test flight of NASA’s moon-bound Space Launch System rocket, but this year could see even more action at the launch pad, as a slate of new rockets look to make their debut.

“There’s a lot to look forward to,” said Colleen Anderson, a historian of technology at the National Air and Space Museum in Washington, D.C. “It’s going to be an interesting time with first flights for a lot of new launch vehicles.”

From new boosters to replacing old workhorses to the much-anticipated first flight of a huge rocket billed as the tallest and most powerful ever built, here’s what to look for this year.

It is “designed to use an inherently safe and extremely robust fuel form.”

The future of deep space exploration is near. Rolls-Royce revealed a new image of a micro-reactor for space that it says is “designed to use an inherently safe and extremely robust fuel form.”

The iconic engineering firm recently tweeted the image alongside a caption. It is designing the nuclear fission system as part of an agreement it penned with the UK Space Agency in 2021.

Nuclear propulsion systems for space, which harness the energy produced during the splitting of atoms, have great potential for accelerating space travel and reducing transit times. This could be of particular importance when sending humans to Mars… More.


An asteroid mining startup called AstroForge is preparing to launch two missions to space this year, Bloomberg reports — inaugural, albeit early attempts to extract valuable resources from space rocks.

AstroForge isn’t looking to actually land on an asteroid and start extracting materials just yet. Its first mission to space, slated to launch aboard a SpaceX rideshare in April, will involve testing out ways of refining platinum from asteroid-like materials in space.

Lonnie Reid is nationally recognized in turbomachinery for his knowledge of internal flow in advanced aerospace propulsion systems. He has a long history of integrating the theoretical and experimental elements of fluid dynamics work to expand the database of compressor and fan design. He has not only demonstrated excellent leadership skills in several positions, including as chief of the Internal Fluid Mechanics Division, but has been influential in recruiting and mentoring the next generation of scientists and engineers.

Lonnie Reid was born on September 5, 1935, in Gastonia, North Carolina. After serving in the U.S. Army, he earned a mechanical engineering degree from Tennessee State University. He joined the NASA Lewis Research Center as a research engineer shortly after graduating in 1961 and spent the next 20 years as both a researcher and manager in the Compressor Section of the Fluid Systems Components Division.

In the early 1960s the group focused on improving the performance of high-speed turbopumps that pumped cryogenic propellants in space vehicles. The pumping of liquid hydrogen in near-boiling conditions, referred to as “cavitation,” was a particular concern. The fluids systems researchers improved pump designs and demonstrated the ability to pump hydrogen in cavitating conditions. These were key contributions to the success of the Centaur and Saturn upper-stage rockets.

The dream of a warp drive, a futuristic propulsion system that could allow us to cover astronomical distances at the speed of light or faster, is still alive.

While the idea has historically been relegated largely to the realms of science fiction, a growing number of engineers are hard at work trying to turn it into a reality.
