Get Ready for the Solar Eclipse!
In less than a month (August 21, to be precise) folks across the United States, from Oregon to South Carolina, will be treated to a rare total solar eclipse. Here’s the Pangaea guide to watching this spectacular event. Safety first! Don’t even think about watching the eclipse without proper eye protection. Retailers have been busy...
A Good Day with a Bad Elf

The team over at Esri has joined the MOOC movement with five free GIS-related courses that require only a few...
Laser-powered UAS
As noted in our latest issue about tethered drones, the ability to power UAS from the ground exponentially increases flight times and allows the use of heavier sensor payloads. Tethering accomplishes this at the cost of range, however: generally 200-400’ with commercially available tethering systems. What if a system had the advantages of tethering and...
The Power of Tethered Drones
Before the FAA’s Rule 107 allowing UAS use for commercial work, we waited patiently (and often impatiently) for the day when UAS would be “unleashed.” Ironically, now a new class of UAS gets its power from actually being on a leash. Tethered drones use a hardware tether (as thin as a headphone cord) from the...

In the last issue we raised the question of whether mankind should go back to the Moon as a way to fuel future space exploration.
