New ISS Timelapse: "The World Outside My Window"

The International Space Station is up there right now, taking pictures and sending them back to Earth. Enterprising video editors take those images to assemble stunning timelapse videos like "The World Outside My Window," shown below.

While most videos like this focus on the Earth's beauty alone, this video tries to express what it's like to be an astronaut on the ISS, looking out the window and seeing that beauty all the time. You frequently see the station in these shots, and it doesn't detract from the experience in the slightest. This is beautiful, and worthy of a fullscreen HD presentation. Enjoy:

Editor David Peterson explains:

This montage of time-lapse photography from the International Space Station is collected from many taken in Expeditions 29, 30 and 31.

The previous sequence, 'All Alone In The Night', highlighted night sequences and spectacular aurora light shows and intended to give a feeling of flying through space.

The goal with this sequence was to bring a bit more attention to the station itself, including the humans aboard it, particularly Don Pettit (appearing in the final shot) who took many of the sequences in this montage.

The Fascinating Device Astronauts Use to Weigh Themselves in Space

Most every scale on Earth, from the kind bakers use to measure ingredients to those doctors use to weigh patients, depends on gravity to function. Weight, after all, is just the mass of an object times the acceleration of gravity that’s pushing it toward Earth. That means astronauts have to use unconventional tools when recording changes to their bodies in space, as SciShow explains in the video below.

While weight as we know it technically doesn’t exist in zero-gravity conditions, mass does. Living in space can have drastic effects on a person’s body, and measuring mass is one way to keep track of these changes.

In place of a scale, NASA astronauts use something called a Space Linear Acceleration Mass Measurement Device (SLAMMD) to “weigh” themselves. Once they mount the pogo stick-like contraption it moves them a meter using a built-in spring. Heavier passengers take longer to drag, while a SLAMMD with no passenger at all takes the least time to move. Using the amount of time it takes to cover a meter, the machine can calculate the mass of the person riding it.

Measuring weight isn’t the only everyday activity that’s complicated in space. Astronauts have been forced to develop clever ways to brush their teeth, clip their nails, and even sleep without gravity.

Watch Astronauts Assemble Pizza in Space

Most everyone enjoys a good pizza party: Even astronauts living aboard the International Space Station.

As this video from NASA shows, assembling pizza in zero gravity is not only possible, it also has delicious results. The inspiration for the pizza feast came from Paolo Nespoli, an Italian astronaut who was craving one of his home country’s national dishes while working on the ISS. NASA’s program manager for the space station, Kirk Shireman, sympathized with his colleague and ordered pizzas to be delivered to the station.

NASA took a little longer responding to the request than your typical corner pizzeria might. The pizzas were delivered via the Orbital ATK capsule, and once they arrived, the ingredients had to be assembled by hand. The components didn’t differ too much from regular pizzas on Earth: Flatbread, tomato sauce, and cheese served as the base, and pepperoni, pesto, olives, and anchovy paste made up the toppings. Before heating them up, the astronauts had some fun with their creations, twirling them around like "flying saucers of the edible kind,” according to astronaut Randy Bresnik.

In case the pizza party wasn’t already a success, it also coincided with movie night on the International Space Station.
