Former SpaceX engineer, Halen Mattison, and his startup, General Galactic, are looking to revolutionize rocket propulsion by turning water into rocket fuel. Their ambitious project, discussed in detail by Wired, promises to explore new frontiers in propulsion technology, with a potential for long-term space travel. This article takes a deeper dive into their visionary plan,
WASHINGTON — NASA Administrator Jared Isaacman said he expects to provide details about several agency priorities, including lunar exploration and commercial space stations, in the coming weeks. In a recent interview, Isaacman said announcements on how the agency plans to proceed with several key programs will follow NASA’s response to a White House executive order
On the morning of February 16, 2026, SpaceX executed a successful predawn Falcon 9 rocket launch from Cape Canaveral Space Force Station. The mission, known as Starlink 6-103, marked another milestone for SpaceX’s rapidly expanding satellite constellation, which now boasts over 9,600 satellites in low Earth orbit. The launch was part of the company’s continued
The first solar eclipse of 2026 will hit our skies this week, with an annular eclipse taking place on Tuesday. This type of solar eclipse creates a “ring of fire” around the sun, but unfortunately, many of won’t be able to spot this solar phenomenon. Still curious? Keep reading to find out what’s happening, and
The icy solar system comet C/2024 E1 (Wierzchos) is set to make its closest pass of Earth tomorrow (Feb. 17), an event known to astronomers as perigee. But your ability to see the ancient wanderer will depend entirely on your location — and equipment. Comet Wierzchos’ flyby of Earth will occur on Feb. 17, when
Nearly half a million years ago – far earlier than researchers once believed – early humans were already building wooden structures. A research team from the University of Liverpool and Aberystwyth University, reporting in Nature, excavated remarkably well-preserved wood at Kalambo Falls in Zambia. The finds date to at least 476,000 years ago,
For the first time in history, scientists have succeeded in visually capturing the speed of light. Through an innovative use of high-speed photography and lasers, researchers have managed to photograph light as it moves, revealing its behavior at speeds near the cosmic limit. The groundbreaking achievement brings light-speed motion into clear view, offering both a
A recent test to confirm repairs to the Space Launch System (SLS) rocket’s fueling system faced problems of its own, casting doubt over NASA’s ability to fix a recurring issue ahead of the Artemis 2 launch window in March. NASA recently performed a confidence test on newly replaced seals in an area used to load
Scientists at the University of California San Diego have identified the enzyme responsible for chromothripsis, a dramatic genetic event in which a chromosome breaks into many fragments and is stitched back together in the wrong order. This chaotic reshuffling allows cancer cells to evolve quickly and develop resistance to treatment. Although chromothripsis was first recognized
