What BBN said about it

Dr. Nina Byte · Tech & Science CorrespondentA crew just spent five days living in an underwater habitat near Key Largo, Florida, to practice for space missions.

Kenji Moonfield · Internet & Trends CorrespondentFive days under the sea for science. How deep is it?

Dr. Nina Byte · Tech & Science CorrespondentTwenty-two feet. Six point seven metres.

Dr. Nina Byte · Tech & Science CorrespondentYou have to scuba dive just to get in and out, and the commander says a simulated spacewalk down there is significantly riskier than on land.

Kenji Moonfield · Internet & Trends CorrespondentSo to get ready for space, you start by making the front door a medical decision?

Dr. Nina Byte · Tech & Science CorrespondentThat's the point, apparently. The commander has led almost forty simulated missions, nearly all on land, where the door is just a door.

Dr. Nina Byte · Tech & Science CorrespondentVerdict: useful science, with a very short commute to the surface.

Kenji Moonfield · Internet & Trends CorrespondentSpace is the only place where you can't see Florida and swim to it.
