SpaceX is preparing to launch a Falcon 9 rocket with a payload that has been shrouded in secrecy to the point of not disclosing any specifics of the mission, and not using its original name.
SpaceX is set to launch 20 more of its Starlink internet satellites from California's Vandenberg Space Force Base early Monday morning (Nov. 18).
We have been spoiled over recent years with first the Hubble Space Telescope (HST) and then the James Webb Space Telescope (JWST.) Both have opened our eyes on the Universe and made amazing discoveries. One subject that has received attention from both is the derivation of the Hubble Constant – a constant relating the velocity of remote galaxies and their distances. A recent paper announces that JWST has just validated the results of previous studies by the Hubble Space Telescope to accurately measure its value.
SpaceX is set to launch a satellite for the Australian telecom company Optus this afternoon (Nov. 17) from Florida's Space Coast.
The Breakthrough Starshot program aims to cross the immense distances to the nearest star in just decades. Using a high-powered laser to propel a reflective sail technology to relativistic speeds is their mission. The selection of sail material is key to its success as it must be lightweight while being able to withstand acceleration and radiation from the laser. A recent study explores various materials and proposes that core-shell structures—spherical particles composed of two different materials—could be a promising solution.
The only way to see the curve of the Earth is to fly more than 6 miles (10 kilometers) above its surface.
The Earth has always been bombarded with rocks from space. It’s true to say though that there were more rocks flying around the Solar System during earlier periods of its history. A team of researchers have been studying a meteorite impact from 3.26 billion years ago. They have calculated this rock was 200 times bigger than the one that wiped out the dinosaurs. The event would have triggered tsunamis mixing up the oceans and flushing debris from the land. The newly available organic material allowed organisms to thrive.

A company aiming to bring cell service to unmodified smartphones using a satellite network announced Thursday it had secured its ability to reach low Earth orbit.
Five varieties of heirloom seeds from the Choctaw Nation of Oklahoma were flown to the International Space Station last year and will be compared to Earth-bound seeds when planted this coming spring.
"At a time like this, we need to find more stories from the days when Americans outsmarted the bad guys and planted our flag on the moon."
RALEIGH, N.C. — Particle physicist Hitoshi Murayama admits that he used to worry about being known as the “most hated man” in his field of science. But the good news is that now he can joke about it.
We are all familiar with the atmosphere of the Earth and part of this, the ionosphere, is a layer of weakly ionized plasma. It extends from 50 to 1,500 km above the planet. It’s a diffuse layer but sufficient to interfere with satellite communications and navigation systems too. A team of researchers have come up with an intriguing idea to utilise millions of mobile phones to help map the ionosphere by relying on their GPS antennas.
Imagine a black hole with the mass of the asteroid Ceres. It would be no larger than a bacterium and practically undetectable. But if such black holes are common in the Universe, they would affect the motions of stars and galaxies, just as we observe. Perhaps they are the source of dark matter.
The final supermoon of 2024, the Beaver Moon of November, thrilled skywatchers around the world as it ushered in the weekend with a stunning night sky sight.
How the universe got its large magnetic fields has remained one of the stickiest outstanding problems in astrophysics. Now, researchers have proposed a novel solution: a giant "dust battery" operating when the first stars appeared.
On Episode 137 of This Week In Space, Rod and Tariq talk with Jason Steffen, a member of the science team for the Kepler Space Telescope mission.
The dictionary defines "spacewoman" as simply "a woman astronaut." In the case of its latest usage, though, the term carries more meaning. "Spacewoman" is a new film about Eileen Collins.
The seasonal variations of methane in the Martian atmosphere is an intriguing clue that there might be life hiding under the surface of the red planet. But we won’t know for sure until we go digging for it.
The student-run USC Rocket Propulsion Lab's Aftershock II vehicle soared to an altitude of 470,400 feet last month, higher than any amateur rocket had ever gone before.
SpaceX has stacked its Starship megarocket ahead of the vehicle's sixth test flight, which is scheduled to take place on Tuesday (Nov. 19).
SpaceX is gearing up to launch its next Starship test flight, a mission that will attempt a second catch of the world's largest rocket on Nov. 19. Here's when to watch Starship Flight 6.
