SpaceX is preparing to launch a Falcon 9 rocket from Cape Canaveral Space Force Station in the predawn hours of Saturday with its latest batch of Starlink satellites. The flight comes about a day and a half after the internet constellation experienced a global outage for more than two hours.
The Hubble Telescope and Chandra X-ray Observatory saw an enigmatic intermediate-mass black hole lighting up in X-rays, potentially revealing a way of finding more of them in the future.
The four members of SpaceX's Crew-10 mission on the Expedition 73 crew began packing for home, while also calling down to Earth to share their ongoing work aboard the ISS.
Unlike other superhero superstars, the Fanastic Four have traditionally struggled with the transition to the big screen.
Crew-11 will launch from NASA's Kennedy Space Center in Florida on July 31 atop a Falcon 9 rocket, if all goes to plan.
Blue Origin has announced the payload for the first-ever flight of its Blue Ring spacecraft —Scout Space's Owl space domain awareness sensor.
A new image from the Gemini Observatory might show a stellar companion to Betelgeuse, but the discovery is tentative.
Senegal has officially joined the Artemis Accords, becoming the 56th nation — and the fourth African country — to commit to a shared vision for peaceful and transparent space exploration.
NASA currently leads the nation's planetary defense efforts, but some are calling for the Space Force to take control.
Imagine you're watching a balloon inflate, but instead of slowing down as it gets bigger, it keeps expanding faster and faster. That's essentially what scientists discovered about our universe in 1998 using exploding stars called supernovae. They found that some unknown force, which was subsequently named "dark energy” was pushing space itself apart at an accelerating rate. Now, after analyzing over 2,000 of these stellar explosions, researchers have found hints that dark energy might not be as constant as we thought. It may actually be changing, and possibly weakening over time.
Recreating the environment that most spacecraft experience on their missions is difficult on Earth. Many times it involves large vacuum chambers or wind tunnels that are specially designed for certain kinds of tests. But sometimes, engineers get to just do larger scale versions of the things they got to do in high school. That is the case for a recent test of ExoMars’s parachute system. A team of ESA engineers and their contractors performed a scaled up egg-drop test common in physics classes across the world. Except this one involved a stratospheric balloon the size of a football field and a helicopter.
When rocket engines fire during lunar landings, they don't just kick up a little dust. They unleash massive clouds of high speed particles that behave like natural sandblasting jets, capable of damaging expensive equipment, solar panels, and even entire habitats. As space agencies prepare for permanent lunar settlements through programs like NASA's Artemis mission, understanding this phenomenon has become a matter of survival.
The spacecraft streaks through the darkness of space to reenter Earth's atmosphere.
It's no coincidence that a Klingon with a grudge follows the Enterprise's away mission to Kenfori.
NASA employees and allies protested sweeping science cuts they say are gutting the agency from within. As Congress pushes back on NASA leadership, workers warn the damage is already underway — and the future of U.S. space exploration is at risk.
It's 1961, and four intrepid cosmic explorers journey to space under the leadership of Reed Richards, where they encounter cosmic rays that change them forever. But what are cosmic rays?
The newly waxing Moon passes Mars low in the west, then Spica and Antares while growing more robust. At dawn, Jupiter heads toward Venus.

A Russian Soyuz rocket launched the Ionosfera-M 3 and 4 satellites, along with an Iranian spacecraft and 17 cubesats, toward orbit early Friday morning (July 25).
The frontrunner in this new space race is, of course, NASA. They’re the only organization to have even done it before in the first place, but that was 50 years ago. And while all the technology of the Apollo program still exists in the form of blueprints and designs, all the human expertise that went into crafting those rockets and spaceships is now either retired or passed away. Besides, we’re not spending nearly as much money on the modern space program than we were in the 1950’s and 60’s, and to be quite frank, the Apollo missions were outright dangerous – they had a level of risk that is completely unacceptable to modern standards. When the Apollo 1 disaster happened, killing three astronauts during a launch dress rehearsal in 1967, NASA paused human spaceflight…for less than two years. An event like that today would likely shut down programs for at least a decade.
