If you’re a venturous senior and and sign up to ride the first civilian outer space vehicle when it’s scheduled to fly in 2018, be warned. The company, Blue Origin, states that the ship, New Shepard, will have no toilet facilities aboard.

Ground preps and the space ride are expected to take about 40 minutes for the adventure. However, passengers will be required to take care of any private bathroom needs before boarding. Additionally, because the trip includes bumps and at least several minutes of weightlessness, something similar to seasickness could strike some passengers. They’ll be warned to skip the trip, because there will also be no facilities for barfing aboard.

Also, the fee for the ride could be as much as $250,000 per passenger. So if that lofty figure makes you sick, you may reconsider becoming an elder spaceman or woman.
