A Falcon 9 rocket launched 13 demonstration satellites for a planned U.S. military mega-constellation from Vandenberg Space Force Base in California on Saturday. It was the 61st orbital launch of the year for SpaceX.
For generations, humans have dreamed, speculated, and theorized about the possibility of journeying to distant stars, finding habitable planets around them, and settling down. In time, the children of these bold adventurers would create a new civilization and perhaps even meet the children of Earth. People could eventually journey from one world to another, cultures would mix, and trade and exchanges would become a regular feature. The potential for growth that would come from these exchanges – intellectually, socially, politically, technologically, and economically – would be immeasurable.
SpaceX's Crew-6 astronaut mission will head home to Earth from the International Space Station on Sunday morning (Sept. 3), and you can watch the action live.
Millisecond pulsars are amazing astronomical tools. They are fast-rotating neutron stars that sweep beams of radio energy from their magnetic poles, and when they are aligned just right we see them as rapidly flashing radio beacons. They flash with such regularity that we can treat them as cosmic clocks. Any change in their motion can be measured with extreme precision. Astronomers have used millisecond pulsars to measure their orbital decay due to gravitational waves and to observe the background gravitational rumblings of the universe. They have even been proposed as a method of celestial navigation. They may soon also be able to test the most fundamental nature of gravity.
NASA's Ingenuity Mars helicopter flew for the 56th time last week, staying aloft for nearly 2.5 minutes on a sortie that covered 1,344 feet (410 meters) of ground.
Last month, India tested the parachute system for its Gaganyaan crew capsule using a rocket-powered sled. See footage of the action.

On 1 September 2023 ESA’s all-new Ariane 6 launch vehicle fired its two upper stage engines to simulate the way they will have to operate together at German aerospace agency DLR’s engine test centre in Lampoldshausen, Germany. The test – of the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench.
India’s first dedicated solar science mission Aditya L1 heads spaceward.
India launched its first dedicated solar probe early Saturday morning (Sept. 2), sending the Aditya-L1 spacecraft skyward to tackle some big sun mysteries.
Poor Russia. They can’t seem to get much right. Their most recent failure is their Luna 25 spacecraft. It was supposed to land near the Moon’s south pole but instead crashed into the surface on August 19th.
Chris Hadfield is a retired Canadian astronaut and former commander of the International Space Station (ISS). He gained widespread fame for his social media presence and educational outreach during his time aboard the ISS. Here are some key details about Chris Hadfield:
India’s Chandrayaan-3 lunar lander and rover are quickly checking all the boxes of planned tasks for the mission. Time is short, as the duo are expected to last just 14 days on the Moon’s surface, or one lunar day, the amount of time the solar-powered equipment is built to last. Therefore, we likely only have until about September 6 or 7 to follow any action. But what a joy to watch the updates coming in from ISRO, the Indian Space Resource Organization.
Hotfire testing of the new Ariane 6 rocket has been delayed due to problems with ground equipment.
Validation testing continues for ESA’s all-new Ariane 6 launch vehicle, with firing of its two upper stage engines to simulate the way they will have to operate together during a flight.
Using atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mystery of dark matter in the lab.
Award-winning visual effects master Erik Henry dives into the design and evolution of the Apple TV+ series' alien threats.
Imagine we detect an interstellar object entering our Solar System. At first, astronomers think it’s just another natural interloper like Oumuamua or comet Borisov. We’re warming up to the idea of visitors from other parts of the galaxy, though they’ve been inanimate so far.
An Australian company has released images showing how China constructed its Tiangong space station.
Yesterday I presented a rather pessimistic view about our chances of finding evidence of alien civilizations. That work focused on detecting physical structures on an alien planet, which would take an optical telescope array the size of Saturn’s orbit. Today I’ll talk about a more optimistic view, one which focuses not on physical structures, but the fingerprint of molecules in an alien atmosphere. It’s a task that is not only much easier, it’s something we could do now using the James Webb Space Telescope (JWST).
SpaceX and NASA say the Crew Dragon capsule carrying four Crew-6 astronauts will now depart the International Space Station no earlier than Sept. 3, a 24-hour delay.
Do we stand a better chance against alien invaders in the realm of video games? These are the best alien invasion games of all time.
