PROFESSOR: Welcome back to A20 special relativity. In this last section of this chapter, we talked about applications and implications of special relativity. We talked about the global positioning system. You all have used...
MARSHA is our proposal for a Martian surface habitat. It’s born of a careful response to the Martian environment and a synergy between structural, architectural and construction principles with human experience at the center....
Right now, you’re looking at renderings of human settlements on Mars. These designs were part of NASA’s 3D Printed Habitat Challenge, a 4-year long competition aimed at engineering homes for another planet. The brightest...
This spacesuit, built in 1974, was reported to cost between $15 million and $22 million. Today, that would be about $150 million. Having not delivered any new mission-ready extravehicular suits since then, NASA is...
This is no ordinary rocket engine. Limited by the technology of their times engineers and physicists have theorized this propulsion method for centuries, but the constraints of time may have just lifted with NASA’s...

Consider how you dress when you go outside on a frigid winter day. You have got your shirt, pants, sweater, possibly long underwear, jacket, gloves, helmet or hood, scarf, and boots on. You dressed...
Mars. I always wonder what it would be like to live there And to build there. What would it feel like to look out the window and see an alien landscape millions and millions...
Gravity. It’s what keeps us held to the surface of the Earth and provides a sense of up and down. When we venture into space and orbit the Earth, or some other world, the...
Hi, it’s me, Tim Dodd. The Everyday Astronaut. Rocket engines are incredibly complex machines pushing the boundaries of material science and human ingenuity. And there’s a wide range of ways. You can actually power...
Have you heard about this? Four volunteers will suspend soon spend an entire year inside a small habitat at Johnson Space Center in Houston. It is all part of a program to better prepare...
The term rocket science is often used to describe a concept that is quite difficult to understand but in this video we are going to explain The technology behind rockets and rocket engines in...
– Last video, I was at the Ashton Graybiel Spatial Orientation Lab at Brandeis University, and while I was there one of the team just casually mentioned that they have an artificial gravity laboratory....

So, contrary to what you see in movies spacecraft can’t just sit around in space near a planet because they’d fall right into it. To stay in space we need to get into orbit....
This may look like an astronaut training for the Olympics, but that’s not what’s really happening here. For the ISS, you want a rigid lower half with the ability to rotate around the waist...
