Size of life. “From the largest dinosaurs that roamed the Earth to the smallest insects, the ‘Size of Life’ visualization provides a fascinating perspective on the scale of various life forms across time and space.” ~ learn more
“The concept would skirt delivery headaches. Without a rocket’s size and weight constraints, engineers could also design and construct large structures—over 1,640 feet or 500 meters long—that can’t be shipped from Earth.” ~ learn more
Don’t worry, a new technology could allow the recycling of urine into drikable water. “The prototype, modelled on the “stillsuits” in the sci-fi classic Dune, collects urine, purifies it and can return it to the astronaut through a drinking tube […]
The last one blew up a few minutes into its flight. Maybe this one will too. For most people this probably gets batched in as a cool novelty with the rest of the incrementally cool rocket launches. But when they […]
This sounds pretty scary. Of course, the water level swings up and down, but also the impact of a few years in the down direction seem pretty bad. “The two largest reservoirs in the United States, both on the Colorado […]
“Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.“ | learn more
“After so many decades of the buildup of high-speed clutter in the form of spent rocket stages, stray bolts and paint chips, solid-rocket-motor slag, dead or dying satellites and the scattered fragments from antisatellite tests—all of which could individually damage […]
“We are not short of evidence that microbes can survive in space for extensive times. A favored way to find out is to carry out often multinational studies by placing sample organisms on the surface of the International Space Station.” | learn […]
Aluminum particles stay in the atmosphere when the satellites burn up on reentry. “Wooden satellites would burn up without releasing harmful substances into the atmosphere or raining debris on the ground when they plunge back to Earth.” | learn more
A very intriguing primer on how to conduct war in space. “Scenes from Star Wars, books, and TV shows portray a world very different from what we are likely to see in the next 50 years, if ever, given the […]
