UPDATE: SpaceX and NASA are now targeting 11:16 p.m. ET on Saturday, March 2 for the launch of Crew-8.

SpaceX is preparing to launch three NASA astronauts and one Roscosmos cosmonaut to the International Space Station (ISS).

The Crew-8 mission is targeting Saturday night for liftoff from the Kennedy Space Center in Florida.

As with any rocket launch, calm weather conditions are needed around the launch site and along the flight path to ensure the safety of the vehicle and those onboard.

NASA always turns to the 45th Weather Squadron for forecasts ahead of launches, and at the current time, it’s putting the probability of the flight getting away on time at a reassuring 90%.

“A couple more spectacular weather days are expected across Central Florida before a pattern shift brings in clouds and isolated showers toward the end of the week,” the squadron said, adding that isolated showers are the primary weather concern for launch.

Other launch opportunities are available over the following two days, though the slightly deteriorating weather conditions see the probability of launch slip to 75% on Saturday and 60% on Sunday.

Crew-8, comprising NASA astronauts Michael Barratt, Matthew Dominick, and Jeanette Epps, along with Roscosmos cosmonaut Alexander Grebenkin, recently completed a full rehearsal for launch, according to a SpaceX post on social media on Tuesday.

SpaceX had been targeting early Friday morning for launch but strong winds in the ascent corridor has prompted the team to shift the targeted launch time to 11:16 p.m. ET on Saturday, March 2, for liftoff, which is 9:04 p.m. PT on Thursday, February 29.

The Elon Musk-led spaceflight company will live-stream the early stages of the mission, including the launch, the return of the first-stage booster, and stage separation. Those tuning in will also be able to hear the communications between the crew and Mission Control.

Assuming the rocket launches on time, the Crew Dragon spacecraft will dock with the ISS at 7 a.m. ET (4 a.m. PT) on Saturday, March 2, with NASA’s live stream starting two hours before.

SpaceX Starship reaches orbit for the first time but its historic flight ends early

After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.

Want a city on the Moon? Scientists say there’s not enough water
A billion tons still comes up short

For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.

A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
