Taking fuel to Mars for return flights is heavy and expensive. The $1.9 billion Mars 2020 rover that NASA announced on Friday will include an experiment that will turn carbon dioxide in the Martian atmosphere into oxygen. It could then be used to make rocket fuel and for future astronauts to breathe. The device, named MOXIE, will make about three-quarters of an ounce of oxygen an hour.
The Government Accountability Office issued a report Wednesday saying NASA's Space Launch System is at "high risk of missing" its planned December 2017 initial test flight. The agency doesn't have enough money to get its new, $12 billion rocket system, the largest ever built, off the ground.
The Zero-Gravity Flight Experiment course at Purdue Univ. will see its creation soar to the upper atmosphere to study a new green propellant. The students are partnering with Aerojet Rocketdyne to demonstrate that the propellant can replace the traditional but highly toxic hydrazine fuel. They will design and build their experiment at Purdue, then NASA will launch it on a commercial suborbital rocket flight for weightless experiment time.
The possibility that the civilian jetliner downed over war-torn eastern Ukraine with nearly 300 people onboard was hit by a missile could have profound consequences for the world's airlines. Airlines might have to be more vigilant about avoiding trouble spots, making flights longer and causing them to burn more costly fuel. They may even be forced to reconsider many international routes.
The next big thing in aviation may be really small. With some no bigger than a hummingbird, the hottest things at this week's Farnborough International Airshow are tiny compared with the titans of the sky, such as the Airbus 380 or the Boeing Dreamliner.
NASA has tested new technology designed to bring spacecraft safely down to Mars, with the agency declaring the experiment a qualified success even though a giant parachute got tangled on the way down. Saturday's $150 million experiment is the first of three involving the Low Density Supersonic Decelerator vehicle, which creates atmospheric drag to dramatically slow the spacecraft from Mach 4.
The University of Notre Dame, along with GE and four other public entities, are collaborating on a $36 million project to create a research and testing center to advance the technology of gas turbine engines used for jet aircraft, power generation plants and the oil and gas industry. GE has committed $13.5 million over the next five years to fund research at the Notre Dame Turbomachinery Facility, which was unveiled this week in Indiana.
The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design, but NASA needs a bigger and stronger parachute if it wants to send astronauts there.
A Swiss-made solar-powered aircraft has made a successful inaugural flight as its makers prepare for what they hope will be the first round-the-world solar flight. The aircraft spent 2 hours and 17 minutes in the air above western Switzerland early Monday. The Solar Impulse 2 is a bigger and better version of a single-seat prototype that first took flight five years ago and can theoretically stay airborne indefinitely.
The SuperDraco thruster, an engine that will power SpaceX’s Dragon spacecraft to orbit, has completed a test regimen held over the last month at SpaceX’s Rocket Development Facility in Texas. This qualification test involves a variety of conditions conditions including multiple starts, extended firing durations and extreme off-nominal propellant flow and temperatures.
The commercial cargo ship Dragon returned to Earth from the International Space Station on Sunday, bringing back nearly 2 tons of science experiments and old equipment for NASA. SpaceX's Dragon splashed into the Pacific, just five hours after leaving the orbiting lab. It is the only supply ship capable of returning items to Earth.
Researchers at North Carolina State Univ. have developed new modifications for technology that helps pilots of small aircraft avoid midair collisions. The modified tools significantly improved pilot response times in making decisions to avert crashes. At issue are cockpit displays of traffic information (CDTIs). These are GPS displays used by private pilots to track other aircraft in their vicinity.
More than a dozen media organizations challenged the government's ban on the use of drones by journalists Tuesday, saying the Federal Aviation Administration's position violates First Amendment protections for news gathering. The organizations, including The Associated Press, filed a brief with the National Transportation Safety Board in support of aerial photographer Raphael Pirker.
Space station astronauts got a special Easter treat: a cargo ship full of supplies. The shipment arrived Sunday morning via a Dragon, versus a bunny. The SpaceX company's cargo ship, Dragon, spent two days chasing the International Space Station following its launch from Cape Canaveral. Astronauts used a robot arm to capture the capsule 260 miles above Egypt.
SpaceX is shooting for another launch attempt Friday to deliver supplies to the International Space Station. NASA confirmed the launch date Wednesday, two days after a last-minute rocket leak delayed the mission. Stormy weather, however, is forecast for Friday. Saturday is the backup launch date.
A space station cargo ship will remain Earthbound for a while longer. With just over an hour remaining, the Space X company called off Monday's planned launch because of a rocket leak. A new launch date was not set; the next opportunity would be Friday. Officials said a helium leak in the first-stage of the unmanned Falcon rocket forced the postponement. The launch already had been delayed a full month for various reasons.
NASA is pressing ahead with Monday's planned launch of a supply ship despite a critical computer outage at the International Space Station, promising the situation is safe. Mission managers decided Sunday to proceed with the countdown for the SpaceX capsule, Dragon, already a month late in delivering more than 2 tons of cargo.
On the less glamorous side of space exploration, there’s the more practical problem of waste: in particular, what to do with astronaut pee. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and much-needed drinking water.
Navy researchers have recently demonstrated sustained flight of a radio-controlled P-51 fighter replica fueled by a new gas-to-liquid process that uses seawater as carbon feedstock. The fuel is made using an innovative and proprietary electrolytic cation exchange module that separates gases from water at 92% efficiency. Catalysis converts the gases to liquid hydrocarbons.
Underwater sounds detected by a ship searching the southern Indian Ocean for the missing Malaysia Airlines jet are consistent with the pings from aircraft black boxes, an Australian official says Monday, dubbing it "a most promising lead" in the month-long hunt for the vanished plane.
The European Space Agency is launching the first of six satellites for a new system designed to better monitor climate change, environmental disasters and catastrophes like floods, volcanic eruptions and earthquakes.
Military brass shopping at Asia's biggest defense expo this week have drones high on their to-buy list. But for U.S. manufacturers including General Atomics, which makes the Predator hunter-killer, there's one problem: they can only sell to a few countries because of tight export restrictions.
Additive manufacturing, or 3-D printing, offers a compelling alternative to more traditional manufacturing approaches at NASA, where the need for highly customized spacecraft and instrument components is quite high. The agency has recently launched a number of formal programs to prototype new 3-D printed components, including rocket engine injectors, and 3-D printers for use in space.
The concept of a hypersonic aircraft that takes off from the runway and doesn’t need a rest, inspection or repair is still a unbuilt dream, but Univ. of Cincinnati researchers are developing the validation metrics that could help predict the success or failure of such a model before it is even built, as test data becomes available from component, to sub-system, to the completely assembled air vehicle.
Since the 2003 Columbia shuttle disaster, business professor Peter Madsen at Brigham Young Univ. has examined how NASA recognizes “near-misses”, where narrowly averted failures result in successful outcomes. A new study of NASA’s safety climate finds that recognition of those near-misses goes up when the significance of a project is emphasized, and when organizational leaders emphasize safety relative to other goals, such as efficiency.
