Do you know how many bones are there in your body? When you were a baby you had about 330 bones, and now you have just over 200 bones. The number reduces because some bones join together as you grow. Your wonderful bones work together to protect you and support your body Many Uses ...
Since then, many spacecraft have delivered parts of the ISS into orbit and its assembly has progressed. During this time, the ISS has been manned continuously — as of this writing, 66 astronaut expeditions have successfully reached the station. Expedition 67 began upon the departure of Soyuz ...
Soon, they believed, passengers would board magnetically propelled cars and zip from place to place at high speed, and without many of the maintenance and safety concerns of traditional railroads. The big difference between a maglev train and a conventional train is that maglev trains do not ...
If a smaller galaxy and a much larger companion merge, it can spell the end of the smaller galaxy. Indeed, the European Space Agency'sGaiasurvey has discovered the bones and corpses of cannibalized galaxies littered throughout theMilky Way. One such example is known as theGaia sausage. This...
In the microgravity environment of low Earth orbit, there are many more experiments and research opportunities that can take place in the fields of medical science and developing biomedical technologies that can benefit us on the ground. That's becausemicrogravitymakes alterations to organisms such as...
Each vibrating air molecule passes its vibration on to the next air molecule between the bell and your ear to make the sound wave propagate. When the vibrating air in you ear canal hits your eardrum, it causes the eardrum to vibrate with the same frequency as the sound wave. The bones ...
But while many of his coworkers are calculating asteroids’ past, present and future locations in the cosmos, zapping them with the world’s most massive radar dishes, or considering how to rendezvous and perhaps even gently nudge an asteroid into lunar orbit, Bhaskaran thinks about how to col...
There are many aspects to planning a project. They tend to revolve around the triple constraint of time, cost and scope. One such orbit is resources. Resources can be impacted by all three of those constraints and therefore require a method to control them—sometimes even a resource management...
“You know, there are so many things I could say right now.” Jay looked down at Simon lying on top of Aitch. “However, if I said any of them, my brother would send me into orbit.” If there was anything worse than being trapped in a car with Jay, it was being trapped in th...
From errant pencil leads to bodily fluids, many materials behave differently in the reduced gravity found on the ISS, which means the everyday lives of the astronauts aboard have to change dramatically for the six to 12 months that they are away from their home planet. The astronauts on the...
