Wind turbine blade transportation challenges

The world’s largest airplane, when it’s built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that’s sprouted wings—aeronautical engineering at a preposterous scale. Called WindRunner, and expected by 2030, it’ll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length o

Debugging Behind the Iron Curtain (2010)

news.ycombinator.com Jake Poznanski 2025-11-04 05:53:35

Sergei is a veteran of the early days of the computing industry as it was developing in the Soviet Union. I had the pleasure of working and learning from him over the past year, and in that time I picked up more important lessons about both life and embedded programming than any amount of school could ever teach. The most striking lesson is the story of how and why, in late summer of 1986, Sergei decided to move his family out of the Soviet Union. In the 1980s, my mentor Sergei was writing soft

Dicing an Onion, the Mathematically Optimal Way

news.ycombinator.com The Pudding 2025-11-10 12:54:19

This is a project about onions and math. Why? Because tens of millions of people are curious about how to properly dice an onion, according to YouTube. In 2021, chef and food writer J. Kenji López-Alt broke out some math to get optimal uniform piece sizes. But there is more than one way to dice an onion… This is an onion. (Well, a simplified cross-section of one.) We’ve cut it in half lengthwise, using a sharp knife to reduce the chance of injury and onion-induced crying. From here, what’s the

LHC's New Chip Tackles Radiation Challenges

news.ycombinator.com Michelle Hampson 2025-11-24 09:33:26

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore. Deep in the belly of the Large Hadron Collider (LHC), about 400 million particle collisions are happening in a single second. But as the LHC undergoes upgrades and becomes the High Luminosity-LHC, the number of collisions will increase to an astounding ~1.5 billion collisions or more per second. Capturing all these events via detectors and analyzing the staggering amount of data created from each ex

Synthetic Biology for Space Exploration

news.ycombinator.com Onofri 2025-11-25 18:30:48

The Apollo 11 Moon landing encouraged humankind to consider and investigate life beyond Earth more than 50 years ago1. However, in contrast to its lightning-fast success in terms of the remarkable technology development of the Mercury, Gemini and Apollo programs, human space exploration has been confined in Low Earth Orbit (LEO) for the past 50 years. Nevertheless, other space agencies, such as the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), have joined the two

The ‘Hail Mary’ That Saved NASA’s Juno Camera From Jupiter’s Radiation Hell

gizmodo.com Margherita Bassi 2026-01-01 00:26:35

NASA’s Juno spacecraft, which launched in 2011 to investigate Jupiter’s origin and evolution, travels through the solar system’s most intense planetary radiation fields. When the spacecraft’s JunoCam—a color, visible-light camera—began to suffer the consequences in December 2023, the mission team back on Earth had to think of a remote fix before they lost their chance to photograph the Jovian moon, Io. A relatively simple process was ultimately what enabled the long-distance save: heating the i

How to Watch the Southern Delta Aquariids and Perseids Meteor Showers

wired.com Gretchen Rundorff 2026-01-17 15:00:00

If you want to get into stargazing in 2025, there’s no better place to start than viewing a meteor shower. Meteor showers, or shooting stars, happen when Earth’s orbital path crosses a path of debris left by a comet and that material burns up in the Earth’s atmosphere. Watching a meteor shower is one of the most accessible ways to engage with the night sky. The next showers of the year are the Southern Delta Aquariids—which peak for about a week at the end of July—and the Perseids—which will pe

Starcloud can’t put a data centre in space at $8.2M in one Starship

news.ycombinator.com Unknown 2026-02-16 10:06:28

Abstract Starcloud have claimed that a single 100-ton Starship launch could suffice to create a 40 MW space data centre (SDC) for $8.2 M. My analysis finds that this is infeasible in a single launch but requires a total of upto 22 launches. The SDC’s solar arrays require 4 launches determined by examining existing solar arrays on the ISS. Similarly, the ISS’s radiator benchmarks indicate that 13 launches would be needed for the SDC’s thermal management system. The server racks would require an

Scientists Are Sending Cannabis Seeds to Space

wired.com Sarah Sinclair 2026-02-25 20:16:15

Having dedicated much of his working life to studying the cannabis plant, Radišič believes it is uniquely qualified for space agriculture. It grows fast, adapts well, and has been an agricultural crop for thousands of years. According to Radišič, if at some point we want to grow life on Mars, this makes it an ideal candidate. “Sooner or later, we will have lunar bases, and cannabis, with its versatility, is the ideal plant to supply those projects,” he tells WIRED. “It can be a source of food, p

Preparation of a neutral nitrogen allotrope hexanitrogen C2h-N6

news.ycombinator.com Qian 2026-03-04 22:36:56

As AgN 3 is an excellent reagent for the synthesis of polyazides35 and halogen azides both in the gas phase36 and in solution37,38, we suggest that the reaction of AgN 3 with XN 3 (X = halogen) is a viable route to N 6 (Fig. 1b). The reactions were conducted in either a quartz tube or a U-trap by flowing gaseous Cl 2 through solid AgN 3 under reduced pressure at room temperature (see the ‘Synthesis details’ section in Methods and Supplementary Fig. 1). Apart from the known bands of ClN 3 (ref. 3
