SpaceX receives order for second manned mission

SpaceX has been awarded a second post-certification mission order for its Crew Dragonmanned spacecraft to ferry astronauts to the International Space Station. NASA says that the new contract, which could lead to as many as six flights, will put the United States back into the manned spaceflight game and free US crews to spend more time on scientific research.

Clones of Dolly the sheep grow to healthy old age

Twenty years ago, the famous Dolly the sheep, the first large mammal successfully cloned from an adult cell, was born. Now, at the University of Nottingham, four of her cloned offspring (twin sisters?) are providing science with a better understanding of the cloning process and showing that clones can live to a healthy old age.

ExoMars uses new navigation technique to tack for the Red Planet

ESA's ExoMars 2016 Trace Gas Orbiter (TGO) spacecraft zeroed in on Mars today as it successfully conducted a 53-minute course correction burn of its main engine. According to the space agency, the probe used a new ultra-precise navigation technique that fixed its position to within a thousand meters (3,300 ft), allowing it to make a much more efficient and precise change to its trajectory.

Sea Hunter unmanned sub chaser completes first sea trials

The Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) has completed its first round of sea trials, during which main contractor Leidos says it met or surpassed its performance goals. Co-sponsored by DARPA and the Office of Naval Research (ONR), the autonomous 132-ft (42-m) trimaran, which is designed to track potentially hostile submarines for months at a time without a crew, was christened Sea Hunter on April 9 at the Swan Island shipyard in Portland, Oregon.

New Dry Combat Submersible to carry troops to mission areas scuba-free

US Special Forces are in for a drier time as Lockheed Martin and Submergence Group LLC sign a US$166 million contract to supply the US Special Operations Command (USSOCOM) with a new class of combat submersibles. Based on the Lockheed S301i and S302 commercial submersibles, the Dry Combat Submersibles (DCS) replaces the current fleet of Swimmer Delivery Vehicles (SDV) with a new design that allows the soldiers to travel inside the vessel.

South Pole turned into giant neutrino detector

Mentioning Antarctica brings many things to mind, such as ice, penguins, and possibly even dead cities built by Lovecraftian horrors, but a gigantic radiation detector for unravelling the secrets of the Universe probably isn't high on the list. But that's just what an international team of scientists and engineers are building at the South Pole. Called the Askaryan Radio Array (ARA), will use the continent's vast expanses of dense transparent ice as an instrument for seeking radio waves thrown off by high-energy neutrinos from the depths of outer space.

Vibrating boots to help astronauts keep their footing

Research has shown that the low gravity on the Moon can actually make it harder to stay upright as it is harder for astronauts to distinguish up from down. The pressure suits that don't let astronaut's see their feet and their bulky boots don't help proceedings and puts them at constant risk of tripping for a potentially fatal fall. To keep future explorers on their feet, MIT researchers are developing a new space boot that uses built-in sensors and tiny "haptic" motors to help guide the wearer around obstacles by means of vibrations.

Inkjet printed solar cell turns your portrait into a power source

One drawback with solar cells is that flat, pitch-black panels have only limited aesthetic appeal and limits their application, but a team of researchers at Aalto University have come up with an inexpensive inkjet-printed solar cell that can be made into text or images. Designed to be used with low-power devices, it has already shown performance and durability comparable to that of existing organic dye solar cells.

Densest-ever memory system uses individual atoms to store data

Ever since the first practical computers came on the market in the 1950s, scientists and engineers have been seeking ever more compact data storage technologies, which have gone from giant drums to tiny chips. Now scientists at the Kavli Institute of Nanoscience at the Delft University of Technology (TUDelft) have developed a memory technology that achieves the ultimate physical limit by using individual atoms to represent a single bit of data.

SpaceX makes spectacular ground landing after Dragon launch

SpaceX scored a double success today by sending a Dragon cargo ship into orbit and nailing another ground landing. At 12:45 am EDT, the CRS-9 mission lifted off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in Florida, setting an unmanned Dragon cargo ship on course for a rendezvous with the ISS. Shortly afterwards, the first stage Falcon 9 booster flew back to Cape Canaveral, where it landed at Landing Zone 1. This is the second time that the Falcon 9 has managed a landward landing and the first since the Orbcomm 2 mission last December.

Fortieth anniversary of Viking invasion of Mars

Today marks one of biggest moments in the history of space exploration, perhaps second only to the Apollo 11 landing that occurred on the same day in 1969. On July 20, 1976, the unmanned Viking 1 lander became the first spacecraft to successfully land and operate on the surface of Mars. More than just a technological achievement, this feat completely altered our view of the Red Planet in a way that kept future planetary exploration from being seriously curtailed, and paved the way for an ambitious new generation of Mars missions.

Radiation bombardment from ancient supernovae may have triggered climate

Shakespeare said that the fault lies not in the stars, but in ourselves. Maybe, but scientists at the University of Kansas say that the stars might have some explaining to do. According to computer models, a pair of supernovae that exploded 300 light years away between 1.7 and 8.7 millions of years ago could have released radiation that seriously affected life on prehistoric Earth and may even have triggered an ice age.

BAE Systems' Broadsword Spine turns solider's clothing into power/data hub

Electronics have become so much a part of modern warfare that batteries are now as important as bullets in the supply chain. And with the average combat pack weighing in at over 90 lb (41 kg), it's also the reason batteries get "lost" with predictable regularity. In an effort to simplify things and lighten the load, BAE Systems has teamed with Intelligent Textiles Limited to create Broadsword Spine – an electronic textile device incorporated into a soldier's clothing that acts as an invisible data network and power supply by replacing wires and cables with conductive fabrics.

Bacteria could build and power microscopic "wind farms"

Wind farms are well-established alternative power sources, but they do have their detractors who say they are an eyesore. But a new type of wind farm proposed by researchers at Oxford University is unlikely to attract such criticism. They claim computer simulations have demonstrated it is possible that microscopic wind farms could be built and powered by bacteria to provide a steady, albeit small, source of power.

BAE Systems wants to grow military aircraft in chemical vats

Modern military aircraft are so complex that fighters like the F-35 Lightning II or the Typhoon take 20 years to go from drawing board to deployment at phenomenal costs. With design work already starting on next-generation fighters for the 2040s, BAE Systems and the University of Glasgow are looking at a faster, cheaper way to produce unmanned air vehicles (UAV), where they aren't constructed, but grown in computer-controlled chemical vats in a matter weeks.

RemoveDebris to launch space cleanup demonstrator

According to the Surrey Space Centre, there are some 7,000 tonnes (7,716 tons) of space debris circling the Earth, consisting of dead satellites, booster rocket stages, paint chips, and shrapnel from collisions. Whizzing in orbit at tens of thousands of miles per hour, even a small fragment could destroy a satellite. To help clean things up, the Centre has announced that it is leading a mission early next year to send the RemoveDebris demonstrator into orbit to test low-cost technologies that could be used to collect and remove space debris.

One-way shields give riot police the edge

Combating riots is a thankless job, and it isn't helped by the fact that the only thing separating rioters and police is a thin barrier of transparent plastic that allows both sides to see each other clearly. To provide the police with a psychological advantage, Nottingham Trent University undergraduate Ben Palmer has come up with a new riot shield that allows the police to see the rioters clearly, but not vice versa.
