Steam Powered Twin Spacecrafts

Cubesats in Command

 High Theater in Low Earth Orbit
Two cubesats (small satellites) powered by steam performed a complicated and coordinated maneuver in space today.  With the help of NASA on the ground, one of the spacecraft commanded the other to close the 5.5 mile gap between them.  It did so successfully.

Old Fashioned Steam Power
The twin spacecrafts' fuel tanks are filled with water.  Thrusters convert the water into steam which propels the cubesats.  NASA says today's maneuvers demonstrate how small spacecraft can work together on future missions.  NASA adds these spacecraft are designed to operate in swarms.  These space teams could be deployed in the future for deep space exploration and work autonomously to explore new worlds.  NASA plans on sending cubesats to the Moon in 2020.  For a free Kindle borrow of my latest book "Big Space News 2019", go to amazon.com/author/ekane

US Army Invention - Drone Defense Source:  US Army Drone Netting Device Drone Netting Grenade U.S Army researchers have created a 40 mm grenade to protect the armed forces from menacing, enemy or rogue drones.  The defensive drone grenade takes out the drone with a weighted net. Countermeasure - Net Bagging a Drone The net is spring loaded and ejects from the front of the grenade when it nears the drone target.  The net can be triggered remotely by a person on the ground or automatically by an onboard proximity sensor. Drone Defense The net springs open to 30 feet in diameter.  It traps the drone, causing it to fall to the ground.  Word of this new drone defensive technology has just been released.  For more news stories on important innovations, go to  amazon.com/author/ekane
