The UK has a reputation for doing satellite telecommunications and navigation at Earth, so why not provide similar services at the also? ⁦⁩ ⁦

To celebrate our bicentenary, has launched a stunning new set of stamps showcasing 'visions of the universe'. Available for pre-order today!

If this all rings bells, you might be thinking of the Shell Ocean Discovery winner - USV SEA-KIT. That project is not involved - but as SEA-KIT demonstrated, this is the future. Driverless cars on land & robotic ships at sea.

The USVs will be 21m and 37m in length. They will be operated from control rooms in Austin, TX, and Southampton, UK, via satellite links. The USVs will map the seafloor, look for missing stuff (ships, planes, etc) and conduct environmental surveys.

So, this is a fascinating development from , the exploration and sea-floor mapping outfit. It's creating a new company called "Armada" that will command a fleet of Uncrewed Surface Vessels. h/t

I’m struggling with the resilience argument for a Brexit GNSS. Sure, having more sats helps, but if it’s a Carrington flare then they’re all in trouble. I’d chuck (some of) the money (instead) at PNT systems/ ground infrastructure to prevent (e.g) cascade failures.

And they really want to fight over a system that will probably be killed by some future chancellor anyway?

Well, it’s a dumb suggestion because it risks damaging Copernicus for no good reason. It’s doubtful the six candidate missions can be flown even with the benefit of a UK association subscription. With no UK money, some missions will definitely be kicked into the long grass.

Not really sure I understand the UK GNSS reference in the last paragraph. Is it suggesting the UK cannot have access to the EU’s other space programmes (Copernicus, etc) unless/until the UK allows the EU to have access to the Brexit sat-nav system? I just hate lawyer speak.

EU starting position the Future Relationship with the UK. As expected, Galileo PRS opt-in for service use is here. In short, it means that subject to political will UK can still use Galileo for military purposes as originally planned, providing a backup for GPS. H/T

True. People think of Iridium as a satellite phone company. But half its business is now IoT. Argos needs to evolve and this is an opportunity to do that.

I wrote about a while back. There are a lot of satellite IoT start-up projects out there, but it helps if you can run from the outset with an existing subscriber base.

French start-up raises €100m for its Internet of Things constellation. The company name may not mean anything to you but "Argos" might. The venerable system for tracking the movement of animals worldwide. Kinéis has taken over this system.

On Monday I’ll be planning a significant press conference with important new results from the flyby of KBO 2014 MU69 Arrokoth, in a mission science observation planning meeting & in our every Monday mission leadership tag up.

And here's your update on (AKA ). It too has been on the move. In the bottom right of this image you can see the ice segment that everyone long predicted would break free from the Amery Ice Shelf butt is still attached.

It's slimmed down a bit (down from ~5,800km2 to ~5,000km2) but is basically still intact following its departure from the Larsen C Ice Shelf. Once in open water, there's got to be a good chance it will fracture.

So I know everyone's got their eyes on Pine Island Glacier because a biggish calving is imminent, but keep some of your gaze on . It really is motoring. Now poking above 63 degrees S and about to break free of surrounding sea-ice.

Jonny, you might know the answer to this because you’ve covered this story in more detail - but did we know “darksat” has no functional telecoms payload? It’s a dummy Starlink. might confirm also.

Next search should focus on areas A1 & A2 moving outwards into A3 if needed. can search >1000m2/day so might take 20-30+ days to fully scan each priority area:

Not much new coming out of this meeting. Two soon-to-published studies presented. One from modelling how much large telescopes could be impacted; the other from that considers what's shiny on the Starlinks, eg solar arrays.
