The Mars Ascent Vehicle will become the first rocket to launch from another planet for NASA and ESA’s Mars Sample Return mission.
NASA has released footage captured by its Mars Ascent Vehicle (MAV) team as they performed wind tunnel tests at the space agency’s historic Marshall Space Flight Center.
The US space agency has successfully completed wind tunnel tests on 3D-printed scale models of the MAV, a blog post from NASA reveals.

NASA Celebrates Arrival of OSIRIS-REx and Bennu Asteroid Samples on Earth
In a historic moment that marks the culmination of a seven-year interstellar odyssey, NASA’s OSIRIS-REx spacecraft has successfully delivered its first precious cargo to Earth. The long-awaited rendezvous with the asteroid Bennu has yielded a treasure trove of samples that are now undergoing meticulous examination by scientists and researchers.
The momentous touchdown occurred on Sunday, September 24, at the Department of Defense’s Utah Test and Training Range. Subsequently, the valuable package was carefully hoisted onto a waiting helicopter before embarking on the final leg of its journey to a high-security clean room. Access to this pristine environment is strictly limited to a select group of six individuals.
Telegram, the popular messenger with 800 million monthly active users worldwide, is inching closer to adopting an ecosystem strategy that is reminiscent of WeChat’s super app approach. Certain aspects of the ecosystem will be decentralized with help from two heavyweights: Telegram’s crypto partner TON Foundation and WeChat’s owner Tencent.
Telegram has been working on a platform where third-party developers, from games to restaurants, can build mini apps to interact with users. In Telegram’s own words: “Developers can use JavaScript to create infinitely flexible interfaces that can be launched right inside Telegram — and can completely replace any website.”
To build out this super app platform, Telegram relies on a network of infrastructure partners both from the established tech world and the crypto space. Among them is The Open Network (TON) Foundation, which lays the blockchain groundwork for Telegram but operates as an independent organization.
After years of anticipation and hard work by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer) team, a capsule of rocks and dust collected from asteroid Bennu finally is on Earth. It landed at 8:52 a.m. MDT (10:52 a.m. EDT) on Sunday, in a targeted area of the Department of Defense’s Utah Test and Training Range near Salt Lake City.
Within an hour and a half, the capsule was transported by helicopter to a temporary clean room set up in a hangar on the training range, where it now is connected to a continuous flow of nitrogen.
Getting the sample under a “nitrogen purge,” as scientists call it, was one of the OSIRIS-REx team’s most critical tasks today. Nitrogen is a gas that doesn’t interact with most other chemicals, and a continuous flow of it into the sample container inside the capsule will keep out earthly contaminants to leave the sample pure for scientific analyses.
In this video, we explore the biggest construction sites of the future — the ones that will one day provide us with real megastructures of all kinds and purposes.
From space elevators and Dyson spheres, to enormous ships and gargantuan space stations to live in. But we won’t just marvel at their scale — the real questions are: could we really build all these in the near future, what tech do we need to get the job done, and ultimately, will it work as intended, or these megastructures will turn out to be megagraves?
In our analysis we well use real engineering projects, as well as top sci-fi examples from books, movies and also from the unique world of massive multiplayer online game EVE Online.
EVE Online — (https://eve.online/Ridddle_EN_megastructures) It is set in a rich sci-fi universe, where players can create their own character and explore a vast and complex virtual world built according to the well-thought set of consistent in-world rules.
The game is known for its intricate economy, politics, and warfare mechanics, where players can engage in a variety of activities, including mining resources, trading, fighting, and of course, building numerous megastructures with rich customisation options.
“If you can get up to a watt per square meter, it would be very attractive from a cost perspective,” Assawaworrarit says.
The invention taps into a source of energy that’s easily overlooked
The Earth is constantly receiving a tremendous amount of energy from the Sun, to the tune of 173,000 terrawatts. Clouds, particles in the atmosphere, and reflective surfaces like snow-covered mountains immediately reflect 30 percent of that energy out into space. The rest of it ends up warming the land, oceans, clouds, atmosphere, and everything else on the planet.
Standing 3,280 feet (1,000 meters) tall, the Jeddah Tower will dwarf the Burj Khalifa by over 560 feet (172 m).
Jeddah Economic Company (JEC), the firm behind the ambitious Jeddah Tower Project in Saudi Arabia, has announced the resumption of work on the world’s tallest building, media reports have confirmed. The project that began in 2010 came to an abrupt halt in 2017.
Countries in the Middle East have been pouring money into ambitious projects to attract tourism and businesses and reduce their dependence on oil exports for income. The city of Dubai is replete with examples of structures meant to attract people from all over the world, whether one looks at the Palm Islands or the Moon-themed resort.
