Almost 50 years on from the Apollo programme, reality decided to remind the world that blasting humans into orbit with controlled explosions is still full of risk and cannot be taken for granted. Fortunately, in this case, the Soyuz emergency systems, worked as designed, giving the two crew a short but undoubtedly hair-raising ride. This is only the third time a Soyuz has aborted, the last being in 1983, a testament to the extraordinary reliability of this workhorse spacecraft. However, there are now renewed worries over the state of Russia's creaking space infrastructure and its quality control and inspections. Russia is now working on a replacement vehicle to Soyuz - the Federation (see p 26) - but for the crew of the ISS, the need for a Soyuz to return to flight is more urgent, despite food supplies, as the operational life of the current capsule docked to the ISS runs out in early January. With Soyuz currently grounded, the two new US 'space taxis' (Boeing's CST-100 and SpaceX's Crewed Dragon) may just enter service in the nick of time. Both NASA and Roscosmos have expressed confidence in Soyuz-FG, and Soyuz MS-11 is still due to lift-off on 20 December. Should the investigation uncover deeper safety issues, then potentially NASA, Roscosmos and the ISS partners face difficult choices, including the ultimate option of 'de-crewing' the ISS until a US or Russian spacecraft is ready. The option of evacuating humanity's outpost in LEO which has been permanently occupied for nearly 18 years, is probably the safest, yet it is also the one with the worst public and political 'optics' with overtones of surrender - and, like the retirement of Concorde and the Space Shuttle, of progress failing to go forwards.
