‘It’s going to be hair-raising’: high-risk slingshot move will send robot craft to Jupiter

news.movim.eu / TheGuardian · Sunday, 11 August - 08:00

European space scientists will begin a delicate navigation that will take a probe on scenic route to outer solar system

European space scientists will this week attempt one of the most daring operations ever undertaken in interplanetary flight. On Wednesday, they will direct their Jupiter Icy Moons Explorer (Juice) to make a flyby of Earth and its moon and carry out the first double gravity-assist manoeuvre in space.

The delicate, high-risk exercise is vital to the success of the European Space Agency (Esa) mission and is aimed at taking the €1.6bn (£1.4bn) robot craft to its target, Jupiter, by July 2031. There it will begin exploration of two of the giant planet’s moons, Europa and Ganymede, in a bid to find signs of life that may lurk in their ice-covered oceans.

Les deux « naufragés » de Starliner risquent d’être coincés sur l’ISS encore un bon moment

news.movim.eu / Numerama · Thursday, 8 August - 13:35

Si un plan B de rapatriement des deux astronautes coincés sur l'ISS doit être mis en œuvre, celui-ci pourrait ne pas être exécuté avant le début de l'année 2025. Si tel est le cas, ce sera un coup terrible pour Boeing et son programme Starliner.

Welcome to Edition 7.01 of the Rocket Report! We're compiling this week's report a day later than usual due to the Independence Day holiday. Ars is beginning its seventh year publishing this weekly roundup of rocket news, and there's a lot of it this week despite the holiday here in the United States. Worldwide, there were 122 launches that flew into Earth orbit or beyond in the first half of 2024, up from 91 in the same period last year.

As always, we welcome reader submissions , and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Firefly launches its fifth Alpha flight. Firefly Aerospace placed eight CubeSats into orbit on a mission funded by NASA on the first flight of the company’s Alpha rocket since an upper stage malfunction more than half a year ago, Space News reports . The two-stage Alpha rocket lifted off from Vandenberg Space Force Base in California late Wednesday, two days after an issue with ground equipment aborted liftoff just before engine ignition. The eight CubeSats come from NASA centers and universities for a range of educational, research, and technology demonstration missions. This was the fifth flight of Firefly's Alpha rocket, capable of placing about a metric ton of payload into low-Earth orbit.

Retired engineer discovers 55-year-old bug in Lunar Lander computer game code

On Friday, a retired software engineer named Martin C. Martin announced that he recently discovered a bug in the original Lunar Lander computer game's physics code while tinkering with the software. Created by a 17-year-old high school student named Jim Storer in 1969, this primordial game rendered the action only as text status updates on a teletype , but it set the stage for future versions to come.

The legendary game—which Storer developed on a PDP-8 minicomputer in a programming language called FOCAL just months after Neil Armstrong and Buzz Aldrin made their historic moonwalks—allows players to control a lunar module's descent onto the Moon's surface. Players must carefully manage their fuel usage to achieve a gentle landing, making critical decisions every ten seconds to burn the right amount of fuel.

In 2009, just short of the 40th anniversary of the first Moon landing, I set out to find the author of the original Lunar Lander game, which was then primarily known as a graphical game, thanks to the graphical version from 1974 and a 1979 Atari arcade title . When I discovered that Storer created the oldest known version as a teletype game, I interviewed him and wrote up a history of the game . Storer later released the source code to the original game, written in FOCAL, on his website.

Une erreur de la Nasa a fait craindre un scénario cauchemar pour les astronautes

news.movim.eu / Numerama · Thursday, 13 June, 2024 - 10:20

La Nasa a diffusé un son très inquiétant dans sa vidéo en direct de l'ISS. Le message indiquait qu'un astronaute était victime d'un accident de décompression. Il s'agissait en fait d'une erreur.
