A small spacecraft the size of a mini-refrigerator is packed with cutting-edge “green” technology. NASA’s Green Propellant Infusion Mission, or GPIM, will prove a sustainable and efficient approach to spaceflight. The mission will test a low toxicity propellant and compatible systems in space for the first time.  This technology could improve the performance of future missions by providing for longer mission durations using less propellant.

In this photo, a Ball Aerospace engineer performs final checks before the spacecraft shipped to NASA’s Kennedy Space Center in Florida for launch processing. GPIM is one of four unique NASA technology missions aboard the June 2019 SpaceX Falcon Heavy launch of the U.S. Air Force Space and Missile Systems Center’s Space Test Program-2 (STP-2).

Elvis Calls for “Space Wilderness” to Protect Solar System From Mining!

Protect solar system from mining ‘gold rush’, say scientists
Proposal calls for wilderness protection as startup space miners look to the stars

Great swathes of the solar system should be preserved as official “space wilderness” to protect planets, moons and other heavenly bodies from rampant mining and other forms of industrial exploitation, scientists say.
The proposal calls for more than 85% of the solar system to be placed off-limits to human development, leaving little more than an eighth for space firms to mine for precious metals, minerals and other valuable materials.

Astronomer: Use Lasers as Earth’s “Porch Light” to Attract Aliens

By MIT News – Re-Blogged From WUWT

Via MIT News and the “Astronomers with frickin’ laser beams on their heads” department comes this odd idea.

If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light — a beacon strong enough to attract attention from as far as 20,000 light years away.
