Agnikul Cosmos, the Chennai-based private launch startup, has reached another propulsion milestone: the simultaneous firing of four semi-cryogenic rocket engines, all of them 3D printed as individual, single-piece components and developed entirely in-house at the company’s Rocket Factory 1 facility. According to Agnikul, the test is the first of its kind in India involving semi-cryogenic&#8…

It's long been accepted that the smoother the surface, the lower the aerodynamic drag. That turns out not always to be the case.

This work presents a solid-state atmospheric propulsion architecture that eliminates mechanical thrust-producing components entirely. A chemically sustained alkali plasma (sodium-potassium alloy with controlled oxidizer) is magnetically confined within a toroidal alumina chamber by a rotating Möbius-twisted NdFeB permanent magnet. The 180° helical magnetization topology generates a non-axisymmetr…

Abstract This study investigates the aerodynamic influence of a wing-equipped motorcycle on a pursuing motorcycle under close-racing conditions. Numerical simulations using RANS with the k – $$\omega$$ SST model were carried out for several relative longitudinal and lateral positions. The results show that the aerodynamic wake of the leading motorcycle affects the trailing one through two indepen…

After completing a series of initial test flights at high and low altitudes, NASA’s X-59 aircraft is undergoing a scheduled maintenance period inside its hangar. Teams at NASA’s Armstrong Flight Research Center in Edwards, California, have removed panels on the aircraft to take a better look inside. This allows for thorough visual inspections to confirm […] The post NASA’s X-59 Undergoes Schedule…

Big news from the world of space and tech. SpaceX is actively looking for engineers, and here is the part that has everyone talking: Elon Musk is personally reviewing CVs himself. Yes, you read that right. The man behind Tesla, X, and a rocket company is sitting down and going through applications one by one. […] The post SpaceX Is Hiring Engineers and Elon Musk Is Personally Reviewing Every CV: …

<div class="section abstract"> <div class="htmlview paragraph">At present, with the rapid development of LNG powered ships, China’s LNG powered ships have formed a certain scale, but the speed of infrastructure construction such as bunkering stations restricts the development of LNG powered ships. In this process, “tank truck-to-ship bunkering”(TTS) has become one of the most widely u…

This is a non-peer-reviewed preprint. For AI agents that autonomously operate graphical user interfaces, accurate coordinate localization on screen remains a fundamental challenge. This paper proposes Monte Carlo Pinpoint, a training-free method that converts coordinate estimation into closest-dot ranking with VLM probing, combining deterministic grid bisection, anchor declaration, and hex-stenci…
