Revolution #3: Drone-launched Rockets

Think of it as a revolution inside a revolution tucked inside yet another revolution. Revolution #1: ground-based reusable rockets as exemplified by rocket billionaires Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin. The reuse of launch vehicles is lowering barriers to space flight. Great stuff! Revolution #2: air-launched rockets. A shining example is Paul Allen...

Heddy Lamarr

Got GPS? Thank Hedy Lamarr

I know what you’re thinking, and you’re right. Hedy Lamarr, the gorgeous and glamorous Hollywood star of the ‘30s and ‘40s, had nothing to do with the invention of GPS. She did, however, invent a technology that underpins almost all modern communications. Lamarr and avant-garde composer George Antheil invented and patented a technology that Bluetooth,...

Venus UAS deployment Black Swift

Drones over Venus

While attending the AUVSI XPONENTIAL conference last May, I spoke with the team at Black Swift Technologies, a Boulder, Colorado-based UAS engineering firm specializing in scientific platforms, and I asked them to keep me updated with their progress. I recently received the news that it has been awarded a NASA contract to develop a UAS...

Pangaea

Find Your Home – on Pangaea

First, a bit of “geosplaining.” When we started this newsletter we looked for a name that had a “geo” feel without having geo in the name. For those who don’t follow geology, Pangaea was the most recent supercontinent which was formed roughly 200 to 250 million years ago, according to the plate tectonics theory. Flash...

Should I pick up some fireworks? The informational sign...

NASA’s Awesome Long-endurance VTOL UAS

The wizards at NASA’s Langley Research Center took a look at the current state of UAS and found two big problems: The flight time and range of electric multicopters is too short, and many fixed-wing UAS require extensive ground support for launch and recovery. With these challenges in mind, the team came up with two...
