Direct-ticket sales are another cost-saving tactic. If you go to anInternettravel site to book a flight, the site gets a cut of the ticket price from the airline. The same thing happens if you use a travel agent. Some budget airlines use the age-old cost-cutting practice of "cutti...
The SRBs are solid rockets that provide most of the main force or thrust (71 percent) needed to lift the space shuttle off the launch pad. In addition, the SRBs support the entire weight of the space shuttle orbiter and fuel tank on the launch pad. Each SRB has the following parts: so...
Astronaut candidates also must pass a long-duration physical. Generally, astronaut candidates greatly exceed these requirements and have substantial experience in isolated, confined environments similar to space. See NASA's website for more information about the qualifications and process, which opens up...
But on actually eyeballing that form, I realized that I could buy an unflown, 3-by-5-foot cotton flag for just $15… at a mandatory shipping cost of $10.75. Paying that much for shipping bothered me when I can get to and from the Capitol for $6 and change via Metro, less if I...

MOTORS. In this article, we will guide you through the process to build and fly model rockets similar to the ones you can buy in hobby shops. The engines you will build have a thrust output similar to a Estes A8-3 rocket motor which is a perfect flight profile for smaller launch ...
Turn your eyes to the sky and it's likely you'll see more than a few vapor trails—the wispy white lines that jet planes scribble on the great blue canvas stretched above our heads. At the dawn of the 20th century, the very idea of powered flight seemed, to many, like a ludicrous ...
This makes it unnecessary to outfit SpaceShipOne with a complicated system of pumps and plumbing to combine the oxidizer with the fuel during flight. In the next section, we will get inside SpaceShipOne. Comparison To give you an idea of the difference in speed between SpaceShipOne and White ...

Crew Dragon, Starliner and NASA’s own Orion capsule — designed to return humans to the moon later this decade — all launch atop rockets rather than being strapped to the side of them. In this new era of rocketry with commercial companies largely leading the way, Hale said the challenge ...
