In an interview, Elon Musk said that if gravity on Earth had been only slightly stronger, it would have been impossible to build orbital rockets. If this is true, presumably certain astronomical observations which are filtered out by the atmosphere or the magnetic field of the earth couldn’t have been made. Though I don’t know any specifics.
