schwit1 writes A 20-year-old U.S. military weather satellite apparently exploded for no obvious reason. The incident has put several dozen pieces of space junk into orbit. From the article: “A 20-year-old military weather satellite apparently exploded in orbit Feb. 3 following what the U.S. Air Force described as a sudden temperature spike. The “catastrophic event” produced 43 pieces of space debris, according to Air Force Space Command, which disclosed the loss of the satellite Feb. 27 in response to questions from SpaceNews. The satellite, Defense Meteorological Satellite Program Flight 13, was the oldest continuously operational satellite in the DMSP weather constellation.” Read more of this story at Slashdot.

Lasrick writes: Seth Baum reports on international efforts to ban ‘killer robots’ before they are used. China, Israel, Russia, the United Kingdom, and the United States are apparently developing precursor technology. “Fully autonomous weapons are not unambiguously bad. They can reduce burdens on soldiers. Already, military robots are saving many service members’ lives, for example by neutralizing improvised explosive devices in Afghanistan and Iraq. The more capabilities military robots have, the more they can keep soldiers from harm. They may also be able to complete missions that soldiers and non-autonomous weapons cannot.” But Baum, who founded the Global Catastrophic Risk Institute, goes on to outline the potential downsides, and there are quite a few.

MarkWhittington writes The Washington Post reported that the NASA portion of the president’s 2016 budget proposal is basically status quo though it does provide further funding for a mission to Europa. A Europa probe is near and dear to the new chairman of the House Appropriations Subcommittee that funds NASA, Rep. John Culberson. However, the $18.5 billion budget proposal also funds the asteroid redirect mission, which has come under increasing fire from both Congress and the scientific community. The Houston Chronicle suggested that the final spending bill will be considerably different once congressional Republicans get through with it. Read more of this story at Slashdot. 
August, 13, 1944. The British 8th Army occupies Florence. The Allies finally break out of Normandy. Meanwhile, somewhere in the south of Tuscany, a soldier writes this encrypted message and hides it inside a bullet. In 2015, someone found it and deciphered it. It was the end of a hilariously absurd story. Read more… 
Not all spider silk is created equal. Some spiders spin webs of wet, sticky silk. Others like the Uloborus spider have fluffy webs made of nanoscale filaments. But those fluffy webs are just as good at catching prey, likely thanks to their electrostatic charge. Read more… 
Drones are expensive. Aircraft like General Atomics’s MQ-1 Predator or MQ-9 Reaper cost millions of dollars piece, while the cost of maintaining the fleet stretches into the high tens of billions dollars over their lifespans. The Pentagon’s internal watchdog is aware of this, and recently lambasted the Air Force for not justifying the purchase of 46 Reapers— potentially wasting $8.8 billion of taxpayers’ money . Read more…
