revolutionary idea: pet ownership is not a human right.
cats scratch. dogs bark. certain rare pets are not adapted to living in a regular domestic setting. if your home is not suited for an animal to express their most basic natural behaviours or your situation makes absolutely predictable traits into dealbreakers, then you should not have that kind of pet. “but i want one” is not an acceptable excuse for owning an animal you won’t provide for.
this is an appreciation post to the people who created the artificial gravity controls in star trek. no matter the emergency, no matter how little power the ship has, no matter how completely nonsensical it is for it to function, that thing is. not. turning. off.
Coffee in Space: Keeping Crew Members Grounded in Flight
Happy National Coffee Day, coffee lovers!
On Earth, a double shot mocha latte with soymilk, low-fat whip and a caramel drizzle is just about as complicated as a cup of coffee gets. Aboard the International Space Station, however, even just a simple cup of black coffee presents obstacles for crew members.
Understanding how fluids behave in microgravity is crucial to bringing the joys of the coffee bean to the orbiting laboratory. Astronaut Don Pettit crafted a DIY space cup using a folded piece of overhead transparency film. Surface tension keeps the scalding liquid inside the cup, and the shape wicks the liquid up the sides of the device into the drinker’s mouth.
The Capillary Beverage investigation explored the process of drinking from specially designed containers that use fluid dynamics to mimic the effect of gravity. While fun, this study could provide information useful to engineers who design fuel tanks for commercial satellites!
The capillary beverage cup allows astronauts to drink much like they would on Earth. Rather than drinking from a shiny bag and straw, the cup allows the crew member to enjoy the aroma of the beverage they’re consuming.
On Earth, liquid is held in the cup by gravity. In microgravity, surface tension keeps the liquid stable in the container.
