Starship Rising

[SpaceX @SpaceX]

These vehicles are the first of many – made possible by the tireless effort of SpaceX engineers and technicians – and are designed to enable the core revolutionary capabilities of Starship

[SpaceX @SpaceX]

Starship’s twelfth flight test will debut the next generation Starship and Super Heavy vehicles, powered by the next evolution of the Raptor engine and launching from a newly designed pad at Starbase. The launch is targeted as early as Tuesday, May 19 → https://t.co/2gZQUxS6mm

HOME.

The Artemis II crew has arrived back on Earth, ending a nearly 10-day journey around the Moon. The trip took them farther into space than humans have ever gone before, and now they're safely home with us.

Our closest neighbor in a seemingly endless universe. We have only just begun this adventure.

As United Airlines celebrates their 100th anniversary, we’re grateful for a partnership that has shaped modern aviation.

From pioneering Jeppesen Charts for commercial aviation in the 1930s to leading the shift to a fully paperless flight deck in 2011, we are proud to serve United on every flight, helping pilots operate more efficiently, reduce fuel consumption, and deliver safer, smarter journeys around the world.

Here’s to a century of progress - and the next era of innovation, together.

We are listening to someone flying by the far side of the Moon, giving detailed scientific descriptions of the lunar surface, that they are seeing with their own eyes. I literally do not have words. This is the most incredible thing I have ever witnessed.

@sola_chad This is the ISS not Orion

[Astronomy Vibes @AstronomyVibes]

I literally can’t stop rewatching this launch. It’s indescribably beautiful.

Good morning, world! 🌎

We have spectacular new high-resolution images of our home planet, all of us looking back through the Orion capsule window at our Artemis II astronauts as they continue their journey to the Moon.

[NASA Administrator Jared Isaacman @NASAAdmin]

America’s next leap is underway..
Godspeed Artemis II 🇺🇸

[NASA Administrator Jared Isaacman @NASAAdmin]

Artemis II is on schedule for launch tomorrow at 6:24 p.m ET.

We’re monitoring an extremely complex vehicle, but everything is lining up. The rocket is healthy, the spacecraft is ready, the crew is in position, and the weather is looking good.

America is on track to return to the Moon.

Ship 39 cryoproof operations complete, the first campaign with a next generation Starship V3.
Across several days, engineers tested the vehicle’s redesigned propellant system and its structural strength, including squeeze tests to mimic the forces of future ship catches

[NASA @NASA]

NASA will increase the cadence of the Artemis missions to successfully return humans to the Moon and sustain a lunar presence.

Artemis III will test systems in low Earth orbit to prepare for an Artemis IV Moon landing in 2028. https://t.co/TovtCfQXzf

Some relationships just work.

Jeppesen charts + ForeFlight = a love story built on trust, precision, and showing up when it matters. ✈️❤️

[NASA Administrator Jared Isaacman @NASAAdmin]

NASA will ensure American leadership in space, and we are fortunate to have many commercial and international partners supporting our grand efforts. We will never hit the pause button on progress--we can address the real hardships we face here on Earth while building a more exciting future for our children. America needs NASA. The world needs NASA.

[NASA Administrator Jared Isaacman @NASAAdmin]

Space has been a lifelong passion of mine. I’m grateful to President Trump for giving me the opportunity to serve alongside the best and brightest at NASA.

It was an honor to have stood with @mkratsios47 as @POTUS signed the most impactful executive space policy in generations.

Leading the incredible team at @NASA, we will turn the President’s vision into reality, we will accomplish the near-impossible, and we will inspire the world along the way.
