WASHINGTON — NASA cut short a third attempt to load propellants onto the Space Launch System for a countdown rehearsal April 14 after encountering several problems, including a hydrogen leak.

A NASA spacecraft orbiting Mars has spotted China’s Zhurong rover down on the surface, providing an epic overview of the vehicle’s travels through the red dirt.

The Hubble Space Telescope caught a galaxy on camera that underlies a much larger structure, known as the Virgo Cluster.

Astronomers in the future may not be able to build large complex power-hungry observatories if they want to reduce their carbon footprint in line with greenhouse gas emission requirements, a study suggests.

When the dinosaur-destroying asteroid collided with Earth 66 million years ago, massive amounts of sulfur — volumes more than were previously thought — were thrown high above land into the stratosphere, a new study finds.

NASA scientists have unsealed an extraterrestrial time capsule 50 years after astronauts collected the rock and dust from the moon and sealed it away before returning to Earth.

A circular shape on the seafloor visible on Google Earth is raising cries of “UFO,” but chances are … it’s not aliens. 

WARSAW, Poland — In a bid to secure a domestic launch capability, the Polish Space Agency (POLSA) signed a letter of intent with Virgin Orbit to use the U.S. company’s air-launched LauncherOne system as soon as next year.

WASHINGTON — Arianespace says it is working to remanifest payloads that were to launch on Soyuz rockets while SpaceX says it’s finding ways to accommodate new customers on its vehicles.

WASHINGTON — United Launch Alliance remains confident that its Vulcan Centaur rocket will make its first launch this year while Blue Origin is pushing back the first flight of its New Glenn vehicle.

WASHINGTON — NASA announced March 23 that it will support development of a second lander to transport astronauts to and from the lunar surface to provide competition with SpaceX for the later “sustainable” phase of the Artemis program.

The fine-structure constant is a seemingly random number with no units or dimensions, which has cropped up in so many places in physics, and seems to control one of the most fundamental interactions in the universe.

The European sun-chasing spacecraft Solar Orbiter has snapped the closest images of the sun ever taken, revealing the finest details of our star’s outer atmosphere, the corona. 

Astronomers imaged a weird circle in space in high-definition for the first time as they try to figure out how these mysterious structures form. 

Known as “odd radio circles” (ORCs), the enigmatic shapes were first spotted in 2019 in images from the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. Consisting of 36 colossal dishes located in Western Australia, ASKAP images the entire night sky in radio waves, began seeing circles in various spots.

The industry has ambitions goals that it can accomplish, “but getting the manpower and getting people with the right niche talents into our companies to execute on these ideas is a huge challenge right now,” Cara Sindir, Airbus U.S. Space and Defense chief operations officer, said at the Satellite 2022 conference. “The other part of that challenge is obviously the inflation of salaries. How can we all afford all of these people and how does that play into our business cases?”

WASHINGTON — SpaceX has raised prices for both its Starlink broadband service and for dedicated and rideshare launches, in some cases by up to 20%, citing inflation.
