1st-ever recovered US rocket stage, an artifact from Gemini 5, returns to launch site 60 years later
The first U.S. rocket stage to be recovered after its launch, an artifact from Gemini 5, has landed at the Cape Canaveral Space Force Museum, not far from where it lifted off almost 60 years ago.
A new way to Peer Into the Permanently Shadowed Craters on the Moon, Searching for Deposits of Water ice
Not all flashlights are created equal. Some are stronger, consume more power, or have features such as blinking or strobes. Some aren’t even meant for humans, such as a new project that recently received funding from a NASA Institute for Advanced Concepts (NIAC) Phase I award. Designed by the Ultra Safe Nuclear Corporation (USNC), this flashlight doesn’t emit visible light, but it does emit x-rays and gamma rays, and the researchers on the project think it could be useful for finding resources on the Moon.
SpaceX and NASA targeting Feb. 26 for Crew-6 astronaut launch
SpaceX's sixth contracted astronaut flight to the International Space Station for NASA will launch on Feb. 26, if all goes according to plan.

Leptons: The elementary particles explained
Here we look at what leptons are, how they fit in the Standard Model of particle physics, and their importance in atoms and particle decay.
Astronomers capture radio signal from ancient galaxy at record-breaking distance
Astronomers have detected a radio signal from the most distant galaxy yet. The special radio wavelength could indicate that scientists are ready to investigate how stars formed in the early universe.
Galileo tribute unveiled as Juice says ‘Farewell, Europe’

Scientists Build a Teeny Tiny Tractor Beam
Tractor beams make intuitive sense. Matter and energy interact with each other in countless ways throughout the Universe. Magnetism and gravity are both natural forces that can draw objects together, so there’s sort of a precedent.
China launches 14 commercial satellites into orbit atop Long March 2D rocket (video)
A Long March 2D rocket lifted off from the Taiyuan Satellite Launch Center in northern China on Saturday (Jan. 14), sending 14 commercial satellites to orbit.
Instead of Building Structures on Mars, we Could Grow Them With the Help of Bacteria
NASA and the China National Space Agency (CNSA) plan to mount the first crewed missions to Mars in the next decade. These will commence with a crew launching in 2033, with follow-up missions launching every 26 months to coincide with Mars and Earth being at the closest point in their orbits. These missions will culminate with the creation of outposts that future astronauts will use, possibly leading to permanent habitats. In recent decades, NASA has conducted design studies and competitions (like the 3D-Printed Habitat Challenge) to investigate possible designs and construction methods.
