Virgin Galactic is arguably the leading private space tourism company, having actually built their suborbital craft and carrier and having flown them both. Their web site and publications all look taken from a sci-fi movie, with weightlessness touted as a wonder worth $200,000. One of the slogans Virgin Galactic uses (in the training page) is "Feel the Freedom of Zero G."
However, there's a dirty little secret that no one over at Virgin Galactic is talking about - space-sickness, or its more scientific name, Space Adaptation Syndrome (SAS). Even with medication, most astronauts experience it when they go to space to varying degrees, from mild nausea or a headache to vomiting. SAS is a main reason that EVAs are done only after a few days in space, as vomiting inside a space suit is lethal. A hardly talked-about subject, one of the least pleasant experiences in the first few days in space, as attested by astronauts, is floating vomit. Even very short durations of micro-gravity, experienced on parabolic flights (much shorter than the several minutes on a suborbital flight) have earned airplanes that perform this kind of a flight profile the nick-name Vomit Comet.
