The list of countries to achieve their own successful orbital space launch is a short one, almost as small as the exclusive club of states that possess nuclear weapons. The Soviet Union was first off the rank in 1957, with the United States close behind in 1958, and a gaggle of other aerospace-adept states followed […]
When a Loch Ness Monster story appears at the start of April, it pays to check the date on the article just to avoid red faces. But there should be no hoax with this one published on the last day of March, scientists from the UK’s National Oceanography Centre were conducting underwater robotics tests in […]
It’s rarely appreciated just how much more complicated nuclear fusion is than nuclear fission. Whereas the latter involves a process that happens all around us without any human involvement, and where the main challenge is to keep the nuclear chain reaction within safe bounds, nuclear fusion means making atoms do something that goes against their […]
An Instruction Set Architecture (ISA) defines the software interface through which for example a central processor unit (CPU) is controlled. Unlike early computer systems which didn’t define a standard ISA as such, over time the compatibility and portability benefits of having a standard ISA became obvious. But of course the best part about standards is […]
In 2015, Tim Ellis and Jordan Noone founded Relativity Space around an ambitious goal: to be the first company to put a 3D printed rocket into orbit. While additive manufacturing was already becoming an increasingly important tool in the aerospace industry, the duo believed it could be pushed further than anyone had yet realized. Rather […]
Long before the first airplanes took to the skies, humans had already overcome gravity with the help of airships. Starting with crude hot air balloons, the 18th century saw the development of more practical dirigible airships, including hydrogen gas balloons. On 7 January 1785, French inventor, and pioneer of gas balloon flight Jean-Pierre Blanchard would […]
Have you been to FOSDEM? It’s a yearly two-day megaconference in Brussels, every first weekend of February. Thousands of software and hardware hackers from all across Europe come here each year, make friends, talk software and hardware alike, hold project-specific meetups to drink beer and talk shop, and just have a fun weekend surrounded by […]
Picture a football (soccer ball) in your head and you probably see the cartoon ideal—a roughly spherical shape made with polygonal patches that are sewn together, usually in a familiar pattern of black and white. A great many balls were made along these lines for a great many decades. Eventually, though, technology moved on. Footballs […]
In an ideal world, devoid of pesky details like contact resistance and manufacturing imperfections, you would be able to double the current that can be provided to a device by doubling the number of conductors without altering the device’s circuitry, as each conductor would carry the exact same amount of current as its neighbors. Since […]
In all likelihood, asteroid 2024 YR4 will slip silently past the Earth. Based on the data we have so far, there’s an estimated chance of only 2.1% to 2.3% that it will collide with the planet on December 22nd, 2032. Under normal circumstances, if somebody told you there was a roughly 98% chance of something […]
