Putting to one side a moon base, Mars manned mission and Starlink. What unmanned science projects will the cheap and huge cargo capacity of Starship likely enable? Once Starlink is printing cash, what’s the likelihood of SpaceX setting up a CSR division to help fund some pure science? If the launch cost becomes relatively trivial, by what sort of cost factor could a future James Webb project be engineered at? What would be the science impact of Starship’s larger cargo diameter for future space observatories? Near Earth Object observation should become straightforward and should be a major priority to get solved by the end of the 2020s. Hopefully US Congress push to get that done. For space based gravitational waves detection, I’d like to see a more ambitious range and timescale than 2034 for LISA. But is it the over-engineering required by launch cost that holds this back or the laser technology itself? Using the starship landing architecture, how quickly and cheaply could you engineer a fleet of drones to drill through Europa’s ice sheets? All other suggestions welcome. Once it becomes clear how cheap and reliable Starship will be, I’d hope to see a flood of science projects accelerated off the back of it.
