Comment les activités spatiales peuvent-elles évoluer vers plus de durabilité ?

Remark: This article is from The Conversation France written by Victor DOS SANTOS PAULINO & Nonthapat PULSIRI (V&N) — Experts from Toulouse Business School and The SIRIUS Chair (France)

Lorsque nous parlons d’espace, nous pensons aux étoiles que nous voyons la nuit ou à de bons films de science-fiction. Or, l’espace comprend également tous les satellites et engins qui sont lancés depuis la Terre. Dans certains engins spatiaux, il y a des astronautes, comme l’Américaine Christina Koch ou le Français Thomas Pesquet, qui voyagent pendant plusieurs jours ou mois pour de nombreuses missions.

Pendant ce temps, plus de 8 000 satellites non habités opèrent sur les orbites terrestres pour améliorer la vie quotidienne. Par exemple, les satellites de communication contribuent à améliorer l’accès à Internet dans les zones blanches, les satellites d’observation sont essentiels pour les prévisions météorologiques et les satellites de navigation (GPS) sont indispensables pour les besoins de transport actuels et futurs tels que les véhicules autonomes.

Les progrès dans le secteur spatial offrent aujourd’hui de nouvelles opportunités dans la mise en orbite de constellations de milliers de satellites (par exemple, la flotte Starlink lancée par SpaceX, la société de l’homme d’affaires américain Elon Musk) ou encore dans l’exploitation minière spatiale et le tourisme spatial. Certains pays (dont la France et les États-Unis) ont par ailleurs annoncé que soutenir leur écosystème spatial constituait une priorité pour dynamiser l’économie.

Hyundai Motor Group announces development of lunar exploration rover

Korean automotive manufacturer “moving beyond land, sea, and air mobility to expand into space”.

Hyundai Motor Group, a leading South Korean automotive manufacturer, has announced its entry into the space exploration industry. On April 20, 2023, the company unveiled plans to build a lunar exploration rover development model, in collaboration with several Korean research institutions in the aerospace sector.

The ambitious project aims to create a versatile mobility platform capable of handling various payloads, with cutting-edge autonomous driving technology, solar charging, thermal management, and radiation shielding features. The rover is designed to carry various pieces of equipment on top of it, with a maximum weight of 70 kg.

SpaceX’s successful failure is a wake-up call for Starship’s timeline

SpaceX launched a fully integrated Starship launch vehicle for the first time on Thursday morning, a long-awaited and highly anticipated milestone in the vehicle development program.

The orbital test flight surpassed many expectations. The vehicle cleared Max Q – the point at which the most aerodynamic pressure is exerted on the vehicle – and flew for nearly three minutes despite eight of its 33 rocket engines failing. The rocket reached an altitude of almost 40 kilometers, the point of stage separation, at which time the upper stage failed to separate from the booster, leading to uncontrolled tumbling and a spectacular midair explosion.

Despite its fiery fate, the test was a success: SpaceX got tons of valuable data that will inform future Starship and Super Heavy prototypes. But for all the wins, the test was a stark reminder that Starship mission timelines are in need of a reset.

China plans to build moon bases using robot masons and lunar dirt

The plan: Ding could play a key role in helping China get its future lunar bases off the ground — his research team at HUST has designed several potential moon bases and developed technology that could be used to actually construct them on the moon.

One of those is the “Chinese Super Mason,” an autonomous robot designed to create structures out of bricks. Another is the bricks themselves — Ding’s team has come up with a LEGO-like design for the blocks, which it proposes to make using 3D printing, lasers, and lunar regolith.

They could get a chance to see their ideas put to the ultimate test as soon as 2028, as China reportedly plans to send a Super Mason to the moon to build a lunar brick as part of the Chang’e 8 mission, which is expected to launch in 2028.

Star Maker by Olaf Stapledon (William F. Carduff)

Story of the distant Future.

“Able to journey “out of the body” the time traveller whirls through space and time seeking the Starmaker of the cosmos. He visits many worlds, often during periods of social and political crisis, and finally joins others travellers in developing an unusual mental community.“

Elon Musk Dishes On AI Wars With Google, ChatGPT And Twitter On Fox News

The world’s wealthiest billionaires are drawing battle lines when it comes to who will control AI, according to Elon Musk in an interview with Tucker Carlson on Fox News, which aired this week.

Musk explained that he cofounded ChatGPT-maker OpenAI in reaction to Google cofounder Larry Page’s lack of concern over the danger of AI outsmarting humans.

He said the two were once close friends and that he would often stay at Page’s house in Palo Alto where they would talk late into the night about the technology. Page was such a fan of Musk’s that in Jan. 2015, Google invested $1 billion in SpaceX for a 10% stake with Fidelity Investments. “He wants to go to Mars. That’s a worthy goal,” Page said in a March 2014 TED Talk.
