Following a series of delays, SpaceX, Axiom Space, and NASA are now targeting 2:31 a.m. ET on Wednesday, June 25, (11:31 p.m. PT on Tuesday, June 24) for the launch of Axiom Space’s fourth private astronaut mission to the International Space Station (ISS). The new schedule was announced on Monday night.

The Ax-4 mission will lift off from Launch Complex 39A at the Kennedy Space Center in Florida, with the four-person crew traveling on a SpaceX Crew Dragon spacecraft after launching on a Falcon 9 rocket.

The Crew Dragon is expected to dock with the orbital outpost at about 7 a.m. ET (4 a.m. PT) on Thursday, June 26.

The Ax-4 crew comprises Commander Peggy Whitson, a veteran NASA astronaut and Axiom Space’s director of human spaceflight; Shubhanshu Shukla from the Indian Space Research Organisation, making his first spaceflight; Sławosz Uznański-Wiśniewski, a European Space Agency project astronaut from Poland and on his first trip to space; and Tibor Kapu, representing the Hungarian Space Office, also on his first orbital voyage.

The mission will last about two weeks, during which time the crew will live and work alongside the current ISS inhabitants. To find out more about daily life on the space station, check out these videos made by visiting astronauts over the years.

A number of issues have prevented the Ax-4 mission from getting underway earlier. The launch was first targeted for June 10 but inclement weather forced a delay. June 11 also presented a launch opportunity, but the discovery of a liquid oxygen leak in the Falcon 9 booster prompted engineers to scrub the plan.

A launch effort for June 19 was also called off after a leak was discovered in the Zvezda service module at the ISS. A new target date of June 22 was set, but this was also called off to give the mission team more time to evaluate space station operations. Officials are now satisfied that everything is in order, and so the launch can finally take place.

Space is becoming Bezos and Musk’s next data center site, and we have every reason to worry

The AI boom is coming for the night sky

How Vast's space station will look in orbit.

AI data centers already consume vast amounts of electricity and water on Earth, so Silicon Valley has begun looking somewhere considerably more spacious... literally.

Elon Musk's SpaceX and Jeff Bezos' Blue Origin, along with several other companies, have proposed enormous constellations of satellites designed to operate as orbital data centers. However, environmental groups and former space officials are now warning that putting them into orbit at the proposed scale could have severe consequences for Earth's atmosphere and the night sky.

The first possible exomoon is here, and it makes our Moon look hilariously tiny

Scientists may have found the first exomoon, except this one is the size of Jupiter

This artist’s concept depicts a potential volcanic moon between the exoplanet WASP-49 b, left, and its parent star. New evidence indicating that a massive sodium cloud observed near WASP-49 b is produced by neither the planet nor the star has prompted researchers to ask if its origin could be an exomoon.

We have already discovered more than 6,000 planets outside of our immediate neighborhood. Yet, finding a moon orbiting one of those distant worlds has proved considerably harder. Astronomers may finally have something close to the real deal, but this particular object stretches the word “moon” almost beyond recognition.

Using the European Southern Observatory’s Very Large Telescope in Chile, researchers detected strong evidence for a moon-like object in the CD-35 2722 system. Further observations are still necessary to confirm the discovery, but it could become the first confidently detected natural satellite outside our solar system. There is still one tiny complication though. This moon is apparently massive.

China’s answer to SpaceX’s reusable rockets literally catches boosters in a net

SpaceX catches boosters on legs. China just used a net.

Ammunition, Missile, Weapon

SpaceX's playbook for recovering a rocket booster generally involves legs, a precisely controlled vertical landing, and either a concrete pad or a drone ship.

China just managed to pull off something similar, but in a slightly different way, and on July 10, it tested the method as well.
