Shuttle’s Thermal Protection System

Steve

The Shuttle’s Thermal Protection System (TPS) By Dennis R. Jenkins Originally found at: https://history.nasa.gov/sts1/pages/tps.html   During the original studies of lifting-reentry vehicles during the late 1950s and 1960s, there had been a great debate over the relative merits of active cooling systems versus passive systems for the vehicle structure. The active systems were attractive—on paper—but nobody could quite figure out how to make them work. Therefore, the choices were largely narrowed to either a hot-structure, like that used on the X-15, or a more conventional structure protected by some sort of…

Sonoluminescence, what possibilities can it bring us?

Steve

We are always speculating how other technologies can help our planet and us its residents while at the same time being able to provide energy for us for a long time. It seems that a little known process called Sonoluminescence could be the answer to our ever growing energy concerns. So we can break this topic down into a simple explanation… Sonoluminescence, could potentially be a dedicated power source much like a nuclear reactor is, but with a “star” at the middle burning at a incredibly hot temperature. This “star”, or…

Impossible EM drive to be space tested!

Steve

  Few days ago American Institute of Aeronautics and Astronautics (AIAA) confirmed that a research paper about EM Drive has passed peer review and it will be published in December. Now scientists are taking another step to find out if this controversial engine will work in space or not and for this an actual EM Drive is about to be launched into space for the first time. The EM Drive is as controversial as it gets, because although some clear experiments have put forward that such an engine could actually…
