Ice flows, hazy hydrocarbons among latest Pluto reveals

NASA has detailed fresh discoveries and released the latest batch of images from New Horizons. Sent as the unmanned probe hurtles away from Pluto and out of the Solar System, the new images and readings show a haze that may be the source of Pluto's reddish color and exotic ice that flows like glaciers. The space agency has also shared a spectacular New Horizons flyby simulation video.

Could bomb-proof lining prevent another Lockerbie?

On December 21, 1988, a terrorist bomb detonated in the luggage hold of Pan Am flight 103 causing the 747 airliner to break up over Lockerbie, Scotland, and killing 243 passengers, 16 crew, and 11 people on the ground. To help prevent such a tragedy from occurring again, a European consortium, including the University of Sheffield, is developing Fly-Bag; a flexible fabric and composite liner capable of containing explosions inside an aircraft to improve its chances of survival.

Kepler discovers "Earth's bigger, older cousin"

The odds of finding a habitable planet outside of our Solar System got a significant boost today, as NASA announced the discovery of the most Earthlike world orbiting the most Sunlike star yet. Named Kepler-425b, the new world located 1,400 light-years away in the constellation Cygnus was detected by the Kepler space telescope. It has been characterized by the space agency as "Earth's bigger, older cousin."

Metal foams could provide lightweight radiation shielding

Radiation generally comes under the heading of "things you want to stay away from," so it's no surprise that radiation shielding is a high priority in many industries. However, current shielding is bulky and heavy, so a North Carolina State University team is developing a new lightweight shielding based on foam metals that can block X-rays, gamma rays, and neutron radiation, as well as withstanding high-energy impact collisions.

Fossil fuel emissions threaten to reduce radiocarbon dating reliability

Radiocarbon dating is one of the great tools of science that has allowed archeologists to shed new light on everything from the building of Stonehenge to the beginnings of international trade. However, a new study from the Imperial College London suggests that fossil fuel carbon emissions may be so diluting radioactive carbon isotopes that within decades it will difficult to differentiate between modern artifacts and those over a thousand years old.

Lightweight High-Energy Liquid Laser (HELLADS) prepared for live fire tests

A high-power laser weapon light enough to be carried by tactical aircraft has moved out of the laboratory and onto the testing ground. General Atomics Aeronautical Systems' High-Energy Liquid Laser Defense System (HELLADS) has finished its US Government Acceptance Test Procedure and is on its way to the White Sands Missile Range in New Mexico for live-fire tests.

Boeing awarded first commercial manned space mission contract

Commercial passenger spaceflight has gone on the books with Boeing announcing that it's received the first contract ever issued to a private company to carry out a manned space mission. The NASA task order means that Boeing's CST-100 spacecraft will ferry crews to the International Space Station (ISS) on two to six missions by the company.
