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.
Sometimes, seeing isn't believing until you take something apart. On the 60th anniversary of the launch of Explorer 1 by the United States, I'm prompted to recall the most valuable lesson I ever learned about what it means to be a curator.
With its spherical shape and piecemeal construction, it’s easy to see similarities between the Telstar satellite and the infamous Death Star of the Star Wars films. Aside from a passing resemblance in design, both pieces of technology also address a larger question that has been a focal point for humankind in reality and fantasy: what does space mean for humanity?
If you were freefalling back to Earth from space, would you want to rely on a couple of parachutes and some rockets to protect you from crashing? As crazy as it sounds, that is what allows astronauts aboard the Russian Soyuz capsules to safely return to Earth.
Did you know that some of the coolest photos of Earth from space were not actually taken by satellites? Many were taken by astronauts aboard the International Space Station (ISS). In fact, part of the astronaut training program focuses on how to take photos in space.
This month, the Smithsonian has been highlighting moments of ingenuity—trendsetters, groundbreakers, and individuals whose work embodies the spirit of innovation. As part of the Smithsonian Ingenuity Festival, the National Air and Space Museum celebrated the next generation of space and aviation pioneers, and those in history who paved the way.
Using satellites and robotic rovers, we’ve learned quite a few details about the various planets orbiting our Sun. But what about other stars? What are their planets like? How weird do they get? It turns out, pretty weird.
Sustainable energy has been at the heart of modern innovations large and small, from efficient light bulbs in living rooms to solar panels powering buildings. One of the newest breakthroughs in energy technology can often be found zipping around the streets in front of the Department of Energy (DOE) in Washington, DC—a car powered by hydrogen fuel cells.
