Super heavy booster 20 undergoing full load cryogenic proof testing today at Starbase Massey's test site in preparation for Starship test flight 13.

We have a super frosty Super Heavy folks! B20 is performing its inaugural cryo testing at Masseys.

The difference between Pad 1 (top) and Pad 2 (bottom) is wild. Also, 18 million pounds of thrust helps.

Only gonna get crazier from here.

Interesting development on the sticky grid fin: B1090 has returned to Port Canaveral with its fins *extended*.

This is not typical operating procedure - normally, the fins retract before they get back.

✈️ JUST IN: The X-59 has gone supersonic!

The X-59 achieved supersonic speeds for the first time ever today — a major milestone for NASA’s Quesst mission and an important step toward upcoming flights that will demonstrate its quiet supersonic technology ahead of future community overflights.

Fast now. Quiet soon. 🔊➡️🤫

This week we fully assembled DeepSpace-2, so naturally, that's the subject of the latest episode of Roid Rage. With a built spacecraft, everyone wants to talk about risk. @MattGialich would rather just go solve problems as soon as they pop up.

NEW GLENN: The rear door of the Horizontal Integration Facility (HIF) has been partially opened for the first time since the explosion at Launch Complex-36 last week.

Chang Zheng 9 (CZ-9) is the Chinese governmental Starship competitor (150t to LEO), and it looks like they're planning their own Starfactory to build it in.

Roscosmos has paused Friday’s structural repair efforts inside the Zvezda service module transfer tunnel, known as PrK, as more measurements and data is assessed. Given this development, NASA has instructed the crew members inside the Dragon spacecraft to end the safe haven procedures and return to planned operations aboard the International Space Station. We look forward to working with Roscosmos on a collaborative approach to address the leaks.

Next Ariane 6 launch set for 17 June, in its most powerful configuration yet.

Flight #VA269 will deploy 36 satellites for @Amazonleo's constellation.

What a wonderful start of the day!

We tracked Raptor 3 Sea Level SN170 leaving after testing, setting a new record a day after spotting SN169!

It's an incredible privilege to make these trackings 🦖

Starship Booster 20 has made it to Masseys after rolling out from the production site overnight, for its cryo testing campaign, ahead of Flight 13.
Interestingly the roll took much longer then normal, as the SPMTs broke down a few times, forcing a extended stop, and the booster did a little loop of Massey's following its arrival.

It'd be interesting to find out what the "more extensive" repair operation involves, to the point that the Crew-12 astronauts need to be (I assume) "inside" Dragon and ready to undock in the event those repairs...well, it wouldn't be good for anyone, not least the Cosmonauts conducting the repairs.

🎉 WE HAVE CRITICALITY! 🎉

On June 4, 2026, at around 12:30 MDT, @AntaresNuclear’s Mark-0 microreactor achieved initial criticality at @INL.

It is the first nuclear test reactor to go critical under @ENERGY’s Reactor Pilot Program. Congratulations to Antares on reaching this historic milestone!

[Erik Fraser @efraser77]

Booster 20 and Ship 20, in the same shot. This might be the only matched-number pair we ever see in the same shot.

Booster 20 has exited Mega Bay 1 and is likely headed to Massey's tonight for cryo proofing.

One week later, incredible progress. It’s a 24/7 operation with a solid path forward to launch this year, helped by a lot of luck. @NASA and @USSpaceForce have both been extremely helpful.

This team. Never tell them the odds.

[MattZ @wvmattz]

Sitting atop its thrust simulator stand, Booster 20 makes its appearance as the Mega Bay 1 door opened, moments ago. There is a road closure TONIGHT at midnight to roll to Massey’s. Cryo testing coming soon!

Europe's The Exploration Company (TEC) is teasing a new, reusable, Heavy-lift launch vehicle called Yrene.

It looks like it may sit between Falcon 9 and Falcon Heavy in terms of first stage performance, powered by 9x Bio-methane/Liquid Oxygen "Storm" engines.

More information is expected to be revealed on June 10th.
