We power a new dawn of discovery.

Every era of exploration begins with a shift from looking outward, to moving forward.

At Celestial Space, that shift has already happened. We are turning ambition into capability, and capability into missions that carry us beyond Earth.

Endeavor Launches CSS Weather Sentinel 1 to orbit on version 2 inaugural flight.

LIFTOFF OF ENDEAVOR!

[Celestial Space Corp. @CelestialSpace0]

The Sun powers our world.

It can also disrupt it.

Flying its second mission on Endeavour Flight 5, the CAS-A Solaris satellite family will monitor solar activity in real time, and provide data that helps protect spacecraft, communications networks, and infrastructure from the effects of our solar neighbour.

Because in space, minutes matter.

Endeavor is ready for launch. The 90-minute launch window opens tomorrow at 12:30 p.m. CT with weather currently 80% favorable for liftoff → https://t.co/rjOPuuUT6s

The booster. BN5-1 will attempt a landing on "The Chances Are Never Zero." Which is placed out in the Gulf. Booster will land a little after 8 minutes into the flight.

[Celestial Space Corp. @CelestialSpace0]

Thank you to our amazing partners at @ExpeditionRBX for being the ride to space for our CSSWS-1 satellites!

[Expedition Aerospace @ExpeditionRBX]

This mission will launch CSS Weather Sentinel 1 to a highly elliptic orbit. Weather Sentinel 1 is for monitoring solar activity and act as early warning to orbital and ground based equipment.

[Tasman Space Centre @TasmanSpcCentre]

Every spaceport tells a story. Long before Tasman existed, Vlieland was proving what was possible.

Its story is one of long nights, hard lessons, and historic achievements. As operations prepare to move over, the team at Tasman is proud to become the next chapter in that story.

[Celestial Space Corp. @CelestialSpace0]

Following facility retirement, over 95% of the developed footprint at Vlieland will be removed and restored to its natural condition. Structures picked for their historical significance will be preserved as abandon in place monuments recognising the site's contribution to the development of European commercial spaceflight and the early growth of Celestial Space.

[Celestial Space Corp. @CelestialSpace0]

Today, we are announcing the retirement of operations at the Vlieland Spaceport.

For three years, Vlieland has served as the home of the Osiris program and the birthplace of Celestial Space's launch operations. From early testing to our first orbital missions, this facility has supported all steps of our early growth.

As operations transition to the @TasmanSpcCentre , Vlieland's role as an active site will come to a close. The lessons learned here will continue to shape the next generation of our vehicles, infrastructure, and missions.

[Celestial Space Corp. @CelestialSpace0]

As Celestial Space has grown, operations have gradually expanded beyond the facilities that supported our early programs. In 2024, testing operations were reloacted to the Brancaster Testing Range. This brought an end to activity at the Vlieland test complex. Since then, the site has been disabled and has remained inactive.

More recently, manufacturing and vehicle maintenance has transitioned to the Tasman Space Centre, where new facilities are being developed to support larger growth and cadence.

With launch operations scheduled to relocate in late 2026 following the fifth flight of Osiris, the final activity at Vlieland will come to a close.

[Celestial Space Corp. @CelestialSpace0]

This is not the final answer for our launch infrastructure, and it isn't intended to be. Everything we build serves as both an operational asset and a learning opportunity.

The original Vlieland pad was designed around a very specific set of requirements for an early version of our rocket. It fulfilled that role exceptionally well, but its specialisation limited its ability to support future vehicle upgrades and evolving needs.

With this new pad, we are applying those lessons while learning new ones. Each generation of infrastructure helps improve the next, allowing us to continually refine our approach to launch ops and ground systems design.

[Celestial Space Corp. @CelestialSpace0]

Why do you build a launchpad? Asking for a friend..
🧵

[Celestial Space Corp. @CelestialSpace0]

Vlieland successfully met the requirements placed on it when it entered service. However, as we plan to expand both the cadence and capability of our launch vehicles, a more advanced infrastructure solution is required. Rather than building a small launch pad designed to support a single variant of a single rocket, we are developing a larger, more versatile platform designed to support a broad range of small and medium class launch vehicles.

[Celestial Space Corp. @CelestialSpace0]

Good luck, have fun! :^)

[Expedition Aerospace @ExpeditionRBX]

After 5 months, Expedition Aerospace will debut a brand new rocket: Endeavor Version 2. Featuring the latest engines, systems, and launch pad. The launch is targeted as early as Saturday, June 6th → https://t.co/rjOPuuUT6s

[Celestial Space Corp. @CelestialSpace0]

Space exploration has always brought together people from different backgrounds to achieve something larger than themselves.

This Pride Month, we're celebrating the diversity that has made innovation possible.

[Celestial Space Corp. @CelestialSpace0]

Congrats to our teams at the @TasmanSpcCentre for the near-completion of the High Manufacturing Bay! This building will be the birth site of Europe's most advanced space vehicles, housing some of the largest rocket building tools in the world.
