    Nasa astronaut Anna Fisher, who became the first mother in space, has warned many are unprepared for the rigours of spaceflight and the toll it will take on their bodies. Ms. Fisher said she was sick for the first two days of her mission on the Discovery space shuttle in 1984, expressing concern that people paying hundreds of pounds did not fully appreciate what might happen. The Apollo 8 crews were the first astronauts to report space sickness in 1968, and by Apollo 9 the crews were feeling so bad that their spacewalk had to be rescheduled. NASA’S training aircraft where astronauts can experience weightlessness is colloquially known as the ‘vomit comet’ because it makes people feel so ill.
