The Nasa reveal is hours away. But Westminster is already buzzing. Not about the four names on the Artemis II crew list. About what it means for Britain. Or rather, what it doesn't.
Sources close to the British astronaut corps tell me there is frustration. Deep frustration. The UK has brilliant candidates. Trained, ready, ambitious. But they are hitting a glass ceiling. That ceiling is not space. It is Whitehall.
Artemis is a Nasa-led programme. Britain is a signatory to the Artemis Accords. But that is a treaty, not a ticket. Our astronauts ride shotgun. They are not driving. The crew set to circle the Moon later this year? All American. Canadian on a later flight. Not a single Union Jack.
The message from the space community is clear: if Britain wants a seat at the table, it needs its own table. A sovereign launch capability. A national crew vehicle. A real space programme, not just a subscription service.
I am told the issue is now being raised at the highest levels. A senior government source confirmed that Number 10 is aware of the pressure. But the Treasury is digging in. The cost is eye-watering. Billions, they say. For what? Prestige? The government line is that partnerships are cheaper. Why duplicate when you can cooperate?
That argument is fraying. The Prime Minister is hearing it from his own backbenches. A group of Conservative MPs is forming a 'Space Caucus'. They want a clear roadmap. Dates. Money. A British astronaut on the Moon by 2030. Not just hitching a lift.
Labour is watching. They have their own space policy in development. Shadow ministers are briefing that a Labour government would be bolder. Faster. They smell a split. A wedge issue for the next election.
Today's Nasa announcement will be a spectacle. Beautiful images. Inspiring stories. But for those in the know, it is a reminder. A reminder that Britain is still at the back of the queue. And the queue is getting longer.
The question now: will the Chancellor be moved? Or will he hold the line? The betting in the Lobby is that he will give ground. A small pot. A feasibility study. A token. But the astronauts want more. They want action. And they are not shy about saying so.
One told me: 'We have the talent. The will. The partners. What we lack is a government that believes in us.' That is a dangerous charge. Especially from a national hero.
Watch this space. Parliament is restless. The space race is back. And Britain is determined not to miss its Apollo moment.
