NASA has been involved in the study of air quality for decades from space and with ground sensors, creating a time series of global data records critical to understanding the impacts and causes of air pollution and to helping design solutions. This article highlights a few of the many projects...
NASA has sent robotic probes to other planets in our solar system, and helped astronomers gaze into the depths of the universe. Beyond all that, NASA also has used its satellites and scientists to help us to
And a Japanese 16 has made a plan for constructing buildings on bridges over Tokyo Bay. There are some people who think we will go back to living in 17. But the caves of the future will be quite 18 the caves of the Stone Age. Computers will control light and climate. Farms and ...

The space race has led to technological advancements in the shortest period of time,such as vacuum- sealed(真空密封的) food,fireproof materials and modern vacuum cleaners.(4) D.Yet,we even don't know that some NASA engineers originally developed them for the Apollo program...
So Einstein helped the "Star Trek" writers manipulate space in a science fictional universe, but is it actually possible to build a spaceship that could propel people across vast galaxies in a relatively short period of time? Physicist Miguel Alcubierre has suggested the use of so-called "exotic...
They're removed and disposed of once the spacecraft has landed. The liquid waste is sent into space. How The International Space Station Handles Waste On the International Space Station, liquid wastes are recycled through a special water treatment plant and turned back into drinking water. ...
Once you learn how to use it, that brass astrolabe has a lot of information to impart. iStockphoto/Thinkstock Long before the Texas Instruments LEDcalculator, or even the slide rule, there was another type of computer: the astrolabe. The device took its name, ultimately, from the Greek wo...
