At last, it’s done. The biggest spaceship size chart ever created is now complete and fully operational. 4,268 × 5,690 pixels of technological terror that includes everything from the smaller Star War ships to EVE. According to its author, Dirk Loechel, this is the last update. It’s epic.

The last update

For real this time: This is the final major content update, though if there are issues I’ll still fix them. I also haven’t forgotten I wanted to vectorize the writing. It’s still on the radar. But content-wise, I think that is about all I can put in.

Twenty years ago, a cryptographic puzzle was included in the construction of a building on the MIT campus. The structure that houses what is now MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) includes a time capsule designed by the building’s architect, [Frank Gehry]. It contains artifacts related to the history of computing, and was meant to be opened whenever someone solved a cryptographic puzzle, or after 35 years had elapsed.

The puzzle was not expected to be solved early, but [Bernard Fabrot], a developer in Belgium, has managed it using not a supercomputer but a run-of-the-mill Intel i7 processor. The capsule will be opened later in May.

The famous cryptographer, [Ronald Rivest], put together what we now know is a deceptively simple challenge. It involves a successive squaring operation, and since it is inherently sequential there is no possibility of using parallel computing techniques to take any shortcuts. [Fabrot] used the GNU Multiple Precision Arithmetic Library in his code, and took over 3 years of computing time to solve it. Meanwhile another team is using an FPGA and are expecting a solution in months, though have been pipped to the post by the Belgian.

Fixed-wing planes and helicopters are no longer the darling of the RC world. Even quadcopters and other multirotors are starting to look old hat, as the community looks to ever more outrageous designs. [rctestflight] has slimmed things down to the extreme with this coaxial bicopter build, also known as the Flying Stick (Youtube video, embedded below).

The initial design consists of two brushless outrunner motors fitted with props, rotating in opposite directions to cancel out their respective torques. Each is mounted on a gimbal, setup to provide control authority. iNav is used as a flight controller, chosen due to its versatile motor mixing settings. The craft was built to test its ability at recovery from freefall, as a follow-on from earlier attempts at building a brushless “rocket” craft.

A “spaceplane” that will be able to travel at 25 times the speed just reached a major breakthrough.

Reaction Engines is working with the European Space Agency and the UK Space Agency to develop a hypersonic aircraft that could zip from New York to London in just one hour.

The British aerospace manufacturer has tested the an essential piece of equipment called a precooler, which prevents the plane’s engine from overheating.

London to Sydney in 4 hours, anyone?

In 2013, Lockheed Martin announced development of the successor to the SR-71 Blackbird spy plane.

The SR-71 was capable of reaching speeds over three times the speed of sound, and the SR-72 is intended to have even more impressive specs. Following is a transcript of the video.
