They're back for series THREE and they've brought friends.
Broadcaster Kim McAllister and space expert Dr Murray Collins are now sponsored by both the Data Driven Innovation Programme and the Science and Technology Facilities Council (part of UKRI).
Following the success of "Edinburgh: Space Data Capital" and "Scotland's Secret Space Race", the duo are looking to go even bigger - so they're starting off on the International Space Station.
Listen as they give a flavour of what series three will hold.
Scotland's Secret Space Race peaked at no 6 in the UK Science podcast charts - can they go even higher with this one? Subscribe now!
Great British Lift Off is a Connect production and is sponsored by the Data Driven Innovation Programme and STFC.
