What is a hybrid rocket motor? What advantages does it have over conventional liquid and solid propellant rocket motors? These questions point to an exciting breakthrough that occurred on December 13, 2018, when Virgin Galactic successfully launched VSS Unity on its first suborbital flight.
Una de las muchas razones por la cual me encanta trabajar en el Museo Nacional del Aire y del Espacio es que uno nunca sabe a quién va a conocer. Eso es lo que me pasó un día en mayo cuando mis colegas me preguntaron si quería entrevistar en español, al astronauta de la NASA Danny Olivas, para el programa What’s New in Aerospace, que el Museo ofrece en Internet.
The “Spinners” flying cars from Ridley Scott's 1982 darkly dystopian Blade Runner film reappear in the sequel, Blade Runner 2049. But are there any hopes for flying cars that can operate from rooftops by 2049?
The spacesuits that astronauts wear act as their own personal spacerafts--regulating their temperatures, and made to protect them from micrometeorites while outside of the International Space Station. Join the STEM in 30 team as they create their own "space suits" for some astronaut "Taternauts."
If you’re going to Mars, which do you bring: water or a shovel? The question may sound a little tongue-in-cheek, but it actually goes right to the heart of a critical need for future human exploration of Mars – accessible water. Learn how the MARSIS instrument is helping answer this question.
From dashing off a quick note to creating painstaking calligraphy, we often take writing for granted. But in space, where the stakes are high, how does one write? After all, the ink in pens isn’t held down by gravity, so how do you write upside down?
Last week a United States’ “hit-to-kill vehicle” intercepted and destroyed a mock intercontinental ballistic missile (ICBM) for the first time during a test. Until fifteen years ago, however, anti-ballistic missiles (ABMs) like the one just tested were banned under the Anti-Ballistic Missile Treaty signed by the United States and Soviet Union in 1972.
“A rocket engine is a controlled explosion. So there’s this tension between pushing the technological state of the art and also maintaining safety and reliability," Curator Tom Lassman
The F-1 engine remains the highest thrust rocket engine that NASA has ever flown (1.5 million pounds of thrust). The liquid-fueled engine was used during the Apollo program and sat at the bottom of the Saturn V. The engines were designed to be disposable. After reaching a certain altitude, the engines would shut down and fall back into the ocean.
When the Saturn V was taken out of service, NASA shifted from disposable rocketry to reusable rocketry. In recent years, NASA has revisited the F-1 to help inform the next generation of launch vehicles like the Space Launch System (SLS).
