The Killer Robot Takeover is Inevitable
Posted by Derick Lee in categories: internet, military, robotics/AI, space
VICE gained exclusive access to a small fleet of US Army bomb disposal robots—the same platforms the military has weaponized—and to a pair of DARPA’s six-foot-tall bipedal humanoid robots. We also meet Nobel Peace Prize winner Jody Williams, renowned physicist Max Tegmark, and others who grapple with the specter of artificial intelligence, killer robots, and a technological precedent forged in the atomic age. It’s a story about the evolving relationship between humans and robots, and what AI in machines bodes for the future of war and the human race.

Northrop Grumman Cygnus Launch to the International Space Station
Posted by Alberto Lao in category: space
***Update: Launch is now scheduled for 3:21 p.m. EST on Saturday, Feb. 15. Live coverage begins at 2:45.
Watch a cargo spacecraft lift off from NASA’s Wallops Flight Facility in Virginia on a resupply mission to the International Space Station! 🚀
Launch is targeted at 3:43 p.m. EST on Friday, Feb. 14 for Northrop Grumman’s 13th commercial resupply services mission. A previous launch attempt on Feb. 9 was scrubbed after off-nominal readings from a ground support sensor. The Cygnus cargo spacecraft, loaded with approximately 7,500 pounds of research, supplies and hardware, will launch atop an Antares rocket from the Mid-Atlantic Regional Spaceport. This Cygnus spacecraft is named the S.S. Robert H. Lawrence, in honor of the first African American to be selected as an astronaut.

The ESA is about to turn one of its spacecraft into a fireball
Posted by Genevieve Klien in categories: physics, solar power, space, sustainability
Next week, the European Space Agency is going to jettison a cubesat called Qarman from the International Space Station and watch it burst into a fireball as it reenters Earth’s atmosphere—all on purpose.
What’s the mission: Qarman (short for “QubeSat for Aerothermodynamic Research and Measurements on Ablation”) is a shoebox-sized experiment meant to help researchers better understand the physics at play when objects plummet into the planet’s atmosphere and burn up. Qarman was brought up to the ISS in December during a cargo resupply mission. On February 17, it will be cast back out into space and begin slowly drifting toward Earth before entering the atmosphere and burning up in about six months.
Tell me more: Qarman has four solar-cell-covered panels that are designed to increase atmospheric drag and hasten reentry. Its nose is made from a special kind of cork that’s typically used in thermal protection systems on spacecraft. Ground testing shows that when the cork heats up, it chars and flakes away a bit at a time. The Qarman team is interested in learning how this process works during reentry.

Newborn giant planet discovered 330 light-years away
Posted by Nare Khachatryan in category: space
But researchers just located a baby giant exoplanet orbiting a young star just 330 light-years from Earth, making it the closest of its kind to us.
The planet is known as 2MASS 1155–7919 b, and it’s located in Epsilon Chamaeleontis Association, a young group of stars seen in our southern sky near the Chameleon constellation.
Researchers from the Rochester Institute of Technology made the discovery using data collected by the European Space Agency’s Gaia space observatory.

This solar telescope just released its first close-up video of the Sun — and it’s stunning
Posted by Nare Khachatryan in category: space
Astronomers using the new Daniel K. Inouye Solar Telescope in Hawaii have released their first public images of the Sun, and they are the most detailed images of our parent star ever taken. Images from the next-generation National Science Foundation (NSF) solar observatory reveal details on the surface measuring just 30 kilometers (18 miles) in diameter.
The new four-meter (157 inch) instrument (the largest solar telescope in the world) recorded images and video of turbulent plasma on the surface of the Sun, providing an unprecedented level of detail for solar researchers.

Giant star Betelgeuse might explode soon, and the next few weeks are critical
Posted by Tracy R. Atkins in category: space
Betelgeuse has been very volatile lately, and astronomers are watching to determine if it’s terminal or just going through a phase.
