  Greenbelt MD (SPX) Apr 24, 2020 A 30th birthday is a big milestone for anyone, and a spacecraft is no exception. Tomorrow, the Hubble Space Telescope celebrates its 30th year in space, but it didn't get to this point without having to overcome its fair share of challenges. Over the years, it has not only been fixed, but continuously upgraded to make it the discovery-producing machine that it is today. Servicing (refueling, fixing and upgrading) spacecraft helps make spaceflight more sustainable, affordable and resilient. In honor of ... read more |

 Tucson AZ (SPX) Apr 22, 2020 
Your phone's GPS, the WiFi in your house and communications on aircraft are all powered by radio-frequency waves, or RF waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor uses the angle at which it receives an RF wave to determine its own relative location. The more precisely i ... more |

 Madison WI (SPX) Apr 15, 2020 
When a fire extinguisher is opened, the compressed carbon dioxide forms ice crystals around the nozzle, providing a visual example of the physics principle that gases and plasmas cool as they expand. When our sun expels plasma in the form of solar wind, the wind also cools as it expands through space - but not nearly as much as the laws of physics would predict.
