View of Starship in space from a Starlink V3 satellite on Flight 13.

This composite is made of imagery from four separate cameras on a single satellite. Six of the satellites were equipped with cameras to scan Starship’s heat shield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions

If you are using the earth as a reference frame, the moon is actually doing a close flyby of Artemis II.

[NASA @NASA]

We see our home planet as a whole, lit up in spectacular blues and browns. A green aurora even lights up the atmosphere. That's us, together, watching as our astronauts make their journey to the Moon.

.@TheOceanCleanup is now intercepting 2 to 5% of global plastic pollution.

I think we should be able to double again this year.

[Jonas Sominka @jonasominka]

@blueorigin @AST_SpaceMobile So what about Blue Moon? NG-4?

[Tony Dunn @tony873004]

The ESCAPADE mission to Mars is about to launch. It will stay near Earth for about 1 year before using an Oberth maneuver to send it to Mars.

[Blue Origin @blueorigin]

BOOSTER TOUCHDOWN! New Glenn returns to its blue origin.

The moment of the jump, captured in hydrogen alpha light to resolve the sun’s atmosphere.

We decided to release the photo in print- both as an up close shot and showing the full disc of the sun, which you can see here: https://t.co/K4DovGV4ni

[Andrew McCarthy @AJamesMcCarthy]

Immense planning and technical precision was required for this absolutely preposterous (but real) view: I captured my friend @BlackGryph0n transiting the sun during a skydive.

This might be the first photo of it's kind in existence. See a video of this moment in the reply 👇

Plasma is better in colour! Watch one of our latest #plasma pulses in our ST40 tokamak, filmed using our new high-speed colour camera at an incredible 16,000 frames per second.

Each pulse lasts around a fifth of a second. What you’re seeing is mostly visible light from the plasma’s edge, glowing pink. The core is simply too hot to emit visible light.

In this footage, lithium is dropped into the plasma. As it interacts, it glows red when excited, then turns green as it becomes ionised, losing an electron. From there, it traces the magnetic field lines, revealing the plasma’s path around the tokamak.

Lithium is the focus of our $52 million ST40 upgrade programme, in partnership with @ENERGY and @energygovuk. This builds on pioneering work at @PPPLab and others that has shown that lithium can significantly improve plasma performance.

This video comes from ongoing research into X-point radiator (XPR) regimes, a promising operating mode for future #fusion power plants that aims to cool the plasma before it reaches plasma-facing components (PFCs), helping to reduce wear without compromising performance.

Fusion research just got a lot more colourful!

Here is a 34 frame stack of Starship as seen from Florida just after Raptor engine shutdown last night.

[Andrew McCarthy @AJamesMcCarthy]

My first shot of a flying object transiting the sun, versus my latest.

The one on the left was an accident, and was done while I was still just a hobbyist. The one on the right was captured with intent, as part of my job.

These are some of the most exciting photos to capture 🔥

[John Kraus @johnkrausphotos]

Fine, you can have more vapor photos!

Starship Flight 10 was unreal. ❤️🚀

See all my photos here down below:

[Andrew McCarthy @AJamesMcCarthy]

One of my favorite captures since I got into this hobby: the aftermath of an X class flare on the sun. These loops trace the invisible magnetic field lines on the sun, while moon-sized gobs of plasma rain back down onto the surface.

Blue Ghost’s shadow seen on the Moon’s surface! We’ll continue to share images and updates throughout our surface operations. #BGM1
