Coming on the heels of another large launch deal, Firefly Aerospace announced it sold up to 20 flights on its Alpha rocket to L3Harris. The agreement would see these missions fly between 2027 and 2031.
Fifteen years ago, the Hubble Space Telescope gazed intently at the infrared glow of galaxies in a tiny fraction of the sky. New research shows how this patch of space has changed since then.

As NASA debates the safety of Boeing’s Starliner spacecraft in the wake of multiple helium leaks and thruster issues, the agency is “getting more serious” about a backup plan to bring the ship’s two crew members back to Earth aboard a SpaceX Crew Dragon, officials said Wednesday.
As Starliner's planned 10-day mission stretches past two months, the next ISS SpaceX launch will now delay into September to give NASA the option of including the Starliner crew on its ride home.
A Long March 6A rocket launched 18 internet satellites Wednesday morning (Aug. 7), kicking off construction of a Chinese constellation that could eventually host 14,000 spacecraft.
The U.S. Federal Aviation Administration (FAA) expects the number of licensed launches each year to continue rising steeply, potentially reaching 338 by 2028.
A new AI-powered algorithm has discovered over 300 polluted white dwarfs in the Milky Way that were overlooked in old telescope data.
Scientists have tracked mysterious, violent blasts of radiation called fast radio bursts to plasma-blowing, highly magnetic dead stars or magnetars.
Researchers using the Gaia space telescope studied some ancient stars near the sun, revealing that our corner of the Milky Way may be billions of years older than once thought.
How do you get an atmosphere at a world that doesn’t have one and can’t keep one? If it’s the Moon, you simply bombard it for millions of years with tiny meteorites. Also, let it sit in the solar wind and see what happens. Both space-weathering processes create a thin “exosphere” just above the lunar surface.
NASA officials aim to add context to some of its recent changes to the manifest of the International Space Station. It will host a media teleconference on Wednesday, Aug. 7, to discuss the timelines of the SpaceX Crew-9 launch, the Crew-8 return to Earth and the impacts to the schedule from the ongoing Boeing Starliner Crew Flight Test.
Primordial black holes are thought to have formed early in the evolution of the universe. None have been discovered yet but if they do exist and they may be plentiful, drifting almost invisibly through the cosmos, then they might account for dark matter. One possible way to search for them is to see the results of their meals and a bizarre new theory suggests low mass black holes could be captured by neutron stars and become trapped inside, devouring them from within. If these strange objects existed then it would make neutron stars less common in locations where black holes would proliferate as observed around Galactic centre.
Mars once hosted a lake larger than any on Earth. The broken-down and dried-up remnants of this ancient lakebed are shown here in amazing detail by ESA’s Mars Express.
Establishing communication with an alien intelligence is one of the news items I, and I’m sure many others, long to see. Since we have started the search for advanced civilisations we have tried numerous ways to detect their transmissions but to date, unsuccessfully. A new paper suggests quantum communication may be the ideal method for interstellar communication. It has many benefits but the challenge is that it would require a receiver over 100km across to pick up a signal. Alas they know we don’t have that tech yet!
A seismic shift occurred in astronomy during the Scientific Revolution, beginning with 16th-century polymath Copernicus and his proposal that the Earth revolved around the Sun. By the 17th century, famed engineer and astronomer Galileo Galilei refined Copernicus’ heliocentric model using observations made with telescopes he built himself. However, it was not until Kepler’s observations that the planets followed elliptical orbits around the Sun (rather than circular orbits) that astronomical models matched observations of the heavens completely.
The next team of astronauts has been announced for Axiom Space's next commercial human spaceflight mission to the ISS.
V889 Herculis is an oddball unlike any other star we've ever seen. The nearby sun-like star rotates in a strange way that defies prediction.
SpaceX's Crew-9 astronaut launch to the ISS has been delayed five weeks to Sept. 24, to allow more time to work out issues with Boeing's Starliner capsule.
New data on the brightest pulsar observed with a telescope on the International Space Station suggests neutron star interiors are "squishy."

NASA is delaying the launch of the next space station crew as it continues to work through thruster issues with Boeing’s Starliner spacecraft. In a blog post, the agency said the launch of the Crew-9 mission, aboard a SpaceX Dragon capsule, is now targeted for no earlier than Tuesday, Sept. 24.
Planets orbiting red dwarf stars may have a harder time hanging on to the conditions needed for life to arise and survive than previously thought, data from NASA's dead space telescope GALEX reveals.
