Navigation requires a reference frame. We need reference frames to tell us where we are with respect to other objects and we need reference frames to tell us how we are oriented with respect to other objects. There is no single universal frame that is used for all operations.
Move over, stiff neck; there's a new spinal problem to reckon with. Doctors are seeing some patients with "text neck"--pain caused by inclining one's head for long periods of time while staring at a smartphone, thus putting extra stress on the spine.
I took off my helmet and it felt like I was holding the anchor of the U.S.S. Nimitz in my hand. Oh great, I thought, how am I ever going to brush my teeth -- the brush will be too heavy!
SpaceX has an impressive half dozen commercial launches to its name and a manifest of launch orders from domestic and international clients stretching into the future. They've managed to do this the old fashioned way, by being cheaper, faster and more reliable.
NASA's successful launch of the Orion spacecraft was an important step, but it is only like dipping a toe in the cosmic ocean. In fact, the future of U.S. space leadership is being starved by lack of funding. Continued neglect will harm our national security, and our economy.
Christopher Nolan's first film since the massive success of his Dark Knight Trilogy is a big movie about the future with with big ambitions, big themes, big images, and big questions about human nature, time, and president-day attitudes and policies. Or lack of same.
There are moments in time when the coincidence of art and reality interact to allow us a glimpse into the context of history. The release of the Christopher Nolan film Interstellar a few days after two catastrophes in our space endeavor gives us one of those moments.
Usually, when a launch goes wrong just a few seconds after liftoff, the problem has something to do with an engine. Perhaps a fuel leak or a clogged fuel line.
The two Commercial Crew Transportation Capability (CCtCap) contracts awarded to Boeing and SpaceX by NASA on September 16 should come as no big surpri...
Scientists, politicians, and artists all drinking out of the same wishing well is the special genius of the Clinton Global Initiative, which just cele...
Last month Russian scientists said they discovered sea plankton on the International Space Station that might be alive and thriving. NASA shed doubt on the discovery, and little has been said since. However, the German Aerospace Center recently responded to questions on the issue, confirming the discovery of "bacterial DNA" but casting doubt on other aspects of the Russian report.
If you grew up in the late '80s watching Double Dare, Nick Arcade and Guts, you probably regarded a trip to Space Camp as the ultimate grand prize. I, however, can clearly remember watching those shows with no desire to go to Space Camp.
"The one that impressed me the most was more of a challenge than a game. The objective is to see how far an astronaut or cosmonaut can travel through the vehicle without touching any sides."
NASA has laid out some pretty sci-fi sounding plans for the next 20 years of space travel, but a more critical mission -- at least for the sustainability of human life here on earth -- may be the one it launched in Mountain View, California, just over two years ago.
Today there is widespread agreement that Mars is our human space exploration "horizon goal." There seems to be less agreement on how safe future human space transportation should be. Public opinion is increasingly influenced by uninformed opinions on social media.
Sam: "Stacy. My name is Sam Factotum, and I represent several artists who are interested in performing out of this world. I understand that there is fierce competition for who will be the first."
