U.S. Army Paratroopers assigned to the 2nd Battalion, 503rd Infantry Regiment, 173rd Airborne Brigade conduct airborne jump at Aviano Air Base in preparation for airborne operation onto Juliet Drop Zone in Italy.
The 173rd Airborne Brigade is the U.S. Army Contingency Response Force in Europe, capable of projecting ready forces anywhere in the U.S. European, Africa or Central Commands' areas of responsibility.
In the never-ending parade of weird phenomena erupting from Hawaii's Kilauea volcano comes a "rain" of green crystals, which have supposedly been spotted on the ground after falling from the sky.
"It is literally raining gems," tweeted Tucson meteorologist Erin Jordan, who posted a photo sent to her by a friend in Hawaii.
The gems are also known as olivine, "a common mineral in basaltic lava, which is what this eruption is producing," said Concord University volcanologist Janine Krippner. "Olivine is formed in hot and deep magmas and is brought up to the surface during an eruption."
Although photos have been posted on social media, no scientists have confirmed any official sightings on the ground.
If verified, this olivine could have fallen out of the lava as it was spewed into the air, U.S. Geological Survey (USGS) scientist Wendy Stovall told Mashable.
It's certainly not unusual to find olivine crystals in most Hawaiian lava rock, both new and ancient. "It's pretty common," Stovall said to Mashable. "There’s often olivine in rocks all over Hawaii."
With tensions still high between Israel and Iran, a new supersonic air-to-surface missile designed for the annihilation of high-quality targets has been developed by Israel Aerospace Industries (IAI) and Israel Military Industry Systems (IMI).
Dubbed “The Rampage” after a popular video-game, it is an accurate supersonic, long-range air-to-ground assault missile with a warhead, rocket engine and advanced navigation suit which allows for precision targeting at a very low mission cost compared to existing solutions.
The US Navy’s fully operational LaWS laser uses six commercial welding lasers to obliterate aerial and seaborne targets. Each shot costs as little as $1; tens of thousands less than conventional weapons.
The "building blocks" for life have been discovered in 3-billion-year-old organic matter on Mars, NASA scientists announced Thursday.
Researchers cannot yet say whether their discovery stems from life or a more mundane geological process. However, “we’re in a really good position to move forward looking for signs of life," said Jennifer Eigenbrode, a NASA biogeochemist and lead author of a study published Thursday in the peer-reviewed journal Science.
The findings were also remarkable in that they showed that organic material can be preserved for billions of years on the harsh Martian surface.
The material was discovered by the Mars Curiosity rover, which has been collecting data on the Red Planet since August 2012. The organic molecules were found in Gale Crater — believed to once contain a shallow lake the size of Florida's Lake Okeechobee.
For the past six years, "the Curiosity has sifted samples of soil and ground-up rock for signs of organic molecules — the complex carbon chains that on Earth form the building blocks of life," according to Science. "Past detections have been so faint that they could be just contamination," the journal said.
Now, samples taken from two different drill sites on an ancient lake bed have yielded complex organic molecules that look strikingly similar to the goopy fossilized building
blocks of oil and gas on Earth.
The rover also discovered traces of methane in the Martian atmosphere, which was reported in a second paper in Science. This is significant because most methane on Earth, for instance, comes from biological sources.
"The detection of organic molecules and methane on Mars has far-ranging implications in light of potential past life on Mars," said Inge Loes ten Kate, a Utrecht University scientist in an accompanying article in Science. "Curiosity has shown that Gale Crater was habitable around 3.5 billion years ago, with conditions comparable to those on the early Earth, where life evolved around that time.
On the new Norwegian Bliss, cruise passengers can drive go-karts on a two-story racetrack, listen to a Beatles cover band inside a replica of Liverpool’s Cavern Club or play laser tag in a space-themed, outdoor arena.
Those are just three of the dozen or so entertainment options on the ship, which cost $1 billion to build and will ply Alaskan waters this summer and the Caribbean in the winter. Prices for a one-week Alaska trip in mid-July range from $2,800 per couple for an inside cabin to more than $11,000 for the company’s exclusive Haven suites.
Gone are the days when entertainment at sea consisted of a lounge act near the mini casino and shuffleboard on the lido deck. As Norwegian Cruise Line Holdings Ltd., Carnival Corp. and Royal Caribbean Cruises Ltd. build ever larger vessels and try to lure younger guests, they’re unleashing an arms race to deliver ever more-elaborate onboard activities.
Carnival’s newest vessel, the 3,960-passenger Horizon, has a Dr. Seuss water park, a Havana-themed night club and an Imax theater. In March, Royal Caribbean christened the industry’s largest ship, the 5,518-guest Symphony of the Seas, featuring an outdoor aquatics arena with acrobats, a zip line and wave machine for onboard surfing.
There are very few missions requiring years of planning and preparation, only to be accomplished in less than six seconds.
There are even fewer facilities where such a mission can take place. The Holloman High Speed Test Track (HHSTT) is a facility that enables test scientists and engineers to meet both of the above criteria.
The test track is a 10-mile long, precision-aligned track that provides scientists and engineers a platform from which to conduct their various missions.
Tests on the track provide valid data on problems which cannot be solved by other ground test means.
The tests are conducted by securing the test item to a rocket-propelled sled and launching the sled to a speed identical to that of which it will encounter in an actual flight.
The first of Britain's new stealth fighter jets have touched on UK soil after a journey across the Atlantic.
The US-made F-35B Lightning jets have been in America since rolling off the production line and have been put through their paces by the first batch Royal Air Force and Royal Navy pilots training to fly them.
The first of the four of the jets, which were stationed at a US Marine Corps base in South Carolina, touched down at RAF Marham at 8.10pm tonight after a journey of between eight and nine hours.
"It's as easy to use as playing Minecraft," Kitty Hawk CEO Sebastian Thrun said as we watched my colleague Rachel Crane pull on a motorcycle helmet.
Rachel and I had just flown into Las Vegas for an exclusive first look at the Silicon Valley single-seat flying machine, Flyer.
Kitty Hawk, funded by Google cofounder Larry Page and led by Thrun, a self-driving car pioneer, attracted nationwide attention when it teased its Flyer prototype last year.
But now Rachel was suiting up to become the first reporter to take flight in a new, sleeker model -- no pilot license required. Expectedly, she was nervous and I was relieved it wasn't me sitting in the pilot's seat. The 250-pound vehicle resembles a cross between a drone and a pontoon plane. Ten propellers twirled around her as I watched from 50 feet away.
