An F9 cannot take 25 t to GEO. F9 does just under 23 t to LEO. To GEO it's about 8 t expended or 5 and a half tonnes with a droneship recovery.

- T-A 3y agoThanks, fixed. I meant Falcon Heavy. And it's actually a little more than that to GTO, but then the thing has to get itself into GEO, so it's not all payload: Falcon Heavy has the second highest lift capability of any operational rocket, with a payload of 63,800 kg (140,700 lb) to low Earth orbit, 26,700 kg (58,900 lb) to Geostationary Transfer Orbit, and 16,800 kg (37,000 lb) to trans-Mars injection. https://en.wikipedia.org/wiki/Falcon_Heavy#Design https://en.wikipedia.org/wiki/Falcon_Heavy#Design
