00:01When working 12 to 14 hour days aboard the International Space Station,
00:05caffeine is, well, a must for many astronauts.
00:08On average, an astronaut may consume about 100 milligrams of caffeine per day.
00:12That's equivalent to one cup of coffee, two cups of tea, or about one can of a typical energy drink.
00:17But in space, they can't just pour a cup of joe.
00:20To get their morning brew, astronauts typically sip from a plastic pouch through a straw.
00:25However, astronaut Don Pettit wanted the comforting feeling of sipping from a mug in his hand.
00:30So he invented another way, the zero-gravity cup, also known as the space cup.
00:35The cup relies on surface tension and the laws of physics to keep the liquid in place, enabling the drinker to take spill-free sips.
00:42Just how does the space cup work? In microgravity liquids will form in globs, or bubbles.
00:47So to keep coffee from floating away, the space cup's specially designed shape ensures that as crew members sip,
00:53the liquid flows through an angled channel, creating an experience like drinking from a mug on Earth.
00:58But there's a wrinkle, getting the water for their brew.
01:01Aboard the space station, crew members actually need to turn yesterday's coffee into today's coffee.
01:07They use a water dispensing unit that takes recycled liquids and the moisture gathered from the air
01:11to provide hot potable water for the crew.
01:14Then they will take a plastic pouch load of the freeze-dried coffee grounds,
01:17connect it to the unit, and fill the pouch with hot water.
01:20From there, crew members can sip their fresh java.
01:23Now one big question looms for the future.
01:25Exactly how much coffee would be enough to sustain a mission to Mars?
01:31Let us try it and cover it together with defyting pressure.
01:35Let's try it out.
01:37What's nice?
01:40Let's try it again make a very nice decision in Arwen x this year.
01:44All right, we're just....
01:45I'm feeling the想 Notting Yesterday and I've done the most great deal in Arwen.
01:47We've had eight minutes left for the ocean unit and just couldn't handle it.
01:49We don't target the ocean digitization aspirations because the sea is lisbub-st Riot.
01:50In the best way I'm feeling the most toward the ocean unit and this past year,
01:51it's not aważ.
01:53You.
01:54You do not do that.
01:55Yeah.
01:56Come so quickly as far as possible,
