Less than a month ago, the government
shot a hurt look at its European neighbours when it finally realised that not being in the EU meant that, er, it wouldn't be a priority in EU plans for space.
Professor Sir Martin Sweeting, of Surrey Satellite Technology Ltd (SSTL), went as far as to warn that the situation threatens the viability of his company.
During the committee's visit to Harwell, ESA representatives also confirmed that the agency had been instructed by the European Commission to restrict access by UK companies to EU projects with security implications.
It isn't all about Galileo, of course. ESA's Copernicus Earth observation programme is also being prodded with the Brexit stick. The witnesses observed that work would likely be shifted from the UK simply as a hedge against potential Brexit disruption.
The uncertainty is already having an impact and with UK companies potentially being hit by "Brexit clauses" in EU space programmes, government support may also be needed.

The conclusions are, however, inescapable. Work that might have come the UK's way pre-Brexit and the skills required will go (and are going) elsewhere while uncertainty remains. The government needs to act quickly on agreements regarding space, customs and movement of people if it is to staunch the flow.
