A spacecraft and its launch vehicle are projected upward by the unbalanced pressure inside the rocket engine. There is high pressure on the closed front end of the rocket’s thrust chamber but much lower pressure on the open back end, where the exhaust gases flow out the chamber’s nozzle....
While many lunar landers use multiple jets that fire on and off, Odysseus has an engine that burns continuously and throttles the power. At first the engine will be in a hard braking phase until it's about 2km from the landing site. Then the spacecraft will tilt so ...
Under this contract, Sierra Space will embark on a groundbreaking research and development initiative, the 10-Year Lunar Architecture (LunA-10) capability study. Sierra Space will focus on integrating oxygen extraction, electrical storage and hydrogen-oxygen engine technology into an architecture for a ...

To slow its speed as the lander approached the surface, it used both a parachute (降落伞) and a retrorocket (减速火箭) in its own “seven minutes of terror” as it moved through the atmosphere. It then landed in the Utopia Planitia area, a large impact basin, part of which was explod...
Performing randomization operations before image rendering obviously allows for greater control, as opposed to applying filter effects on an image at the post-processing level, otherwise known as the “photo-shop” method. All Unreal Engine levels mentioned above can be found at [35] for open ...
Main engine cutoff: Crew-5 is approaching orbit From CNN's Jackie Wattles (NASA/YouTube) The rocket just hit “MECO” – or main engine cutoff. That means the 9 Merlin engines that power the SpaceX rocket’s first-stage — the ones that give the initial thrust at liftoff — are done...
The first test launch of the world’s most powerful rocket ended dramatically as it broke apart in the sky. But there’s still a lot riding on it—including NASA’s ambition to return to the moon.
About 8 minutes after liftoff, cheers could be heard echoing throughout mission control as the Starship was approaching the end of its engine burn — putting it on a path toward Earth’s orbit. But 9 minutes after launch — SpaceX made it clear that it lost video signal with Starship. ...
Using the game engine Unity (https://unity.com, accessed on 19 June 2023), an online interactive viewable 3D model was created, animated with other road users, and put together as a WebGL build on a server of the city of Ghent. A bicycle handlebar at the bottom of the screen created...
