This week, SpaceX workers in South Texas loaded the third full-scale Starship prototype—SN3—onto a test stand ​at the company’s Boca Chica launch site. On Wednesday night, they pressure-tested the vehicle at ambient temperature with nitrogen, and SN3 performed fine. On Thursday night SpaceX began cryo-testing the vehicle, which means it was loaded again with nitrogen, Read more about SpaceX loses its third Starship prototype during a cryogenic test[…]

Our galaxy is a whole lot bigger than it looks. New work finds that the Milky Way stretches nearly 2 million light-years across, more than 15 times wider than its luminous spiral disk. The number could lead to a better estimate of how massive the galaxy is and how many other galaxies orbit it. Astronomers Read more about Astronomers have found the edge of the Milky Way at last[…]

Comet ATLAS (C2019 Y4) is plunging toward the sun, and if it doesn’t fly apart it could soon become one of the brightest comets in years. “Comet ATLAS continues to brighten much faster than expected,” says Karl Battams of the Naval Research Lab in Washington DC. “Some predictions for its peak brightness now border on Read more about Comet ATLAS is Brightening Faster than Expected might be awesome to look at mid May[…]

A SpaceX Falcon 9 rocket aborted a planned launch on Sunday morning at the last second due to an engine power issue. The event produced confusion at the Kennedy Space Center in Florida, where countdown appeared to be proceeding normally. However, the rocket stayed where it was. In a video published by SpaceX, you can Read more about Watch This SpaceX Rocket Abort Its Launch at the Last Second[…]

Astronomers have discovered 139 minor planets lurking at the edge of the Solar System after examining a dataset collected to study dark energy in the universe. Small worlds that circle our Sun in orbits further out than Neptune are labelled trans-Neptunian objects (TNO), with one being the relegated-planet Pluto. Eggheads, led by those at the Read more about 139 minor planets were spotted at the outer reaches of our Solar System.[…]

A star that pulsates on just one side has been discovered in the Milky Way about 1500 light years from Earth. It is the first of its kind to be found and scientists expect to find many more similar systems as technology to listen inside the beating hearts of stars improves. […] Stars that pulsate Read more about New type of pulsating star discovered[…]

After pondering the totality of issues that arose during a December test flight of Boeing’s Starliner spacecraft this week, NASA chief of human spaceflight Doug Loverro said Friday that he decided to escalate the incident. So he designated Starliner’s uncrewed mission, during which the spacecraft flew a shortened profile and did not attempt to dock Read more about NASA declares Starliner mishap a “high visibility close call”[…]

The Starship SN1 prototype was undergoing pressure testing at the Musketeers’ factory at Boca Chica in Texas, USA, by filling its tanks with liquid nitrogen. The base of the rocket appears to have ruptured, sending the structure crashing to the ground, which you can see here: SpaceX supremo Elon Musk himself seemed sanguine about the Read more about Watch Elon Musk’s Mars ferry prototype explode on the pad during liquid nitrogen test[…]

Astronomers have spotted molecular oxygen in a galaxy far far away, marking the first time that this important element has ever been detected outside of the Milky Way. This momentous “first detection of extragalactic molecular oxygen,” as it is described in a recent study in The Astrophysical Journal, has big implications for understanding the crucial Read more about Scientists Found Breathable Oxygen in Another Galaxy for the First Time[…]

SpaceX’s new Starship prototype appeared to burst during a pressure test late Friday (Feb. 28), rupturing under the glare of flood lights and mist at the company’s south Texas facility. The Starship SN1 prototype, which SpaceX moved to a launchpad near its Boca Chica, Texas, assembly site earlier this week, blew apart during a liquid Read more about SpaceX’s Starship SN1 prototype appears to burst during pressure test[…]

In a historic first for satellite operations, a commercial spacecraft “helper” has docked with a working communications satellite to provide life-extension services. The companies involved in the meetup  — Northrop Grumman and Intelsat — hailed the operation, which took place Tuesday (Feb. 25), as the beginning of a new era that will see robotic spacecraft Read more about Two private satellites just docked in space in historic first for orbital servicing[…]

Small-sat flinger Rocket Lab beat the winds to get the mysterious National Reconnaissance Office (NRO) payload off the New Zealand launchpad this morning. After multiple holds due to ground winds, the Electron lifted off at 02:56 UTC on 31 January from the company’s Launch Complex 1 on the New Zealand Mahia Peninsula. Dubbed “Birds of Read more about US’s secret spy payload offloaded: Rocket Lab demos missile muscle with second Electron guided home[…]

This first images from NSF’s Inouye Solar Telescope show a close-up view of the sun’s surface, which can provide important detail for scientists. The image shows a pattern of turbulent “boiling” plasma that covers the entire sun. The cell-like structures—each about the size of Texas—are the signature of violent motions that transport heat from the Read more about NSF’s newest solar telescope produces first images, most detailed images of the sun[…]

DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid.  DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space.  The DART mission is in Phase C, led by APL and managed under NASA’s Solar System Exploration Program at Marshall Read more about NASA to launch projectile (DART) to see if it can deflect asteroids[…]

Ribose is an essential sugar for present life as a building block of RNA, which could have both stored information and catalyzed reactions in primitive life on Earth. Meteorites contain a number of organic compounds including components of proteins and nucleic acids. Among the constituent molecular classes of proteins and nucleic acids (i.e., amino acids, Read more about Extraterrestrial ribose and other sugars found in primitive meteorites[…]

Astronomers at a Chilean observatory were rudely interrupted earlier this week when a SpaceX satellite train consisting of 60 Starlink satellites drifted overhead, in what scientists are apparently going to have to accept as the new normal. Launched into orbit on November 11, the Starlink smallsat train took five minutes to pass over the Cerro Read more about Elon Musk’s Starlink Satellites Are Already Causing a Headache for Astronomers[…]

SpaceX’s first full-scale Starship prototype – Mk1 – has experienced a failure at its Boca Chica test site in southern Texas. The failure occurred late in the afternoon on Wednesday, midway through a test of the vehicle’s propellant tanks. As of a few weeks ago, the Mk1 Starship – which was shown off to the Read more about SpaceX Starship Mk1 explodes during cryogenic loading test[…]

In recent weeks, China’s space program has made news by revealing some of its long-term ambitions for spaceflight. These include establishing an Earth-Moon space economic zone by 2050, which, if successful, could allow the country to begin to dictate the rules of behavior for future space exploration. Some have questioned whether China, which has flown six Read more about China now launches more rockets than anyone in the world: Russia 2nd, US 3rd[…]

While one key official has sought to blame a single individual for the system going dark, insiders warn that organizational chaos, excessive secrecy and some unusual self-regulation is as much to blame. Combined with those problems, a battle between European organizations over the satellite system, and a delayed independent report into the July cock-up, means Read more about EU beurocracy, One man’s mistake, missing backups and complete reboot: What we can figure out about Europe’s Galileo satellites going dark[…]
