    First flight on Mars? Ingenuity helicopter preps for takeoff

    In 1903, Orville and Wilbur Wright flew a plane for 12 seconds, 120 feet in the air, on what is now known as the first powered-controlled flight on Earth. Now, 118 years later, the first powered-controlled attempt at a flight on another planet is about to take place.

    MIT engineers make filters from tree branches to purify drinking water

    The interiors of nonflowering trees such as pine and ginkgo contain sapwood lined with straw-like conduits known as xylem, which draw water up through a tree’s trunk and branches. Xylem conduits are interconnected via thin membranes that act as natural sieves, filtering out bubbles from water and sap.

    The Starship prototype landed for the first time

    The Starship prototype landed for the first time, but it exploded again minutes later: These are the moments. The Starship prototype landed for the first time, but it exploded again minutes later: These are the moments. Another important test was left behind today in the development process of SpaceX's new generation interplanetary spaceship Starship. The highly anticipated test take-off of the new prototype rocket SN10 took place today. Although the Starship prototype successfully…

    The Euphoria of Touching Mars

    Landing on Mars should be boring by now. NASA has been doing it since the 1970s. Last week, the agency did it again, achieving its sixth consecutive soft landing on the red planet, and its eighth total out of nine attempts. As records go, NASA never managed six consecutive controlled landings on the Moon, and either way, mere months after Neil Armstrong’s one small step for a man, the public had collectively tuned out the Apollo program.

    Airbus Hopes to Be Flying Hydrogen-Powered Jetliners With Zero Carbon Emissions by 2035

    The aerospace giant Airbus hopes to put a hydrogen-powered commercial airliner in the sky that will release zero carbon dioxide emissions in the atmosphere. But not until 2035. While 15 years might seem like a long time for research and development given the urgent need to reduce carbon emissions under the Paris climate agreement, processing and storing "clean hydrogen" requires solving an array of complex technical challenges.

    This could be the Air Force's future flying car of choice

    The Air Force is on the hunt for a Jetsons-style flying car, and service officials just got an eyeful of one of their very first prototypes. Secretary of the Air Force Barbara Barrett, Air Force Chief of Staff Gen. Charles Q. Brown, Jr., and Chief Master Sgt. of the Air Force JoAnne S. Bass were among the officials present for the first Agility Prime electric vertical takeoff and landing flight (eVTOL) flight demonstration at Camp Mabry on Aug. 20.

    Highly efficient process makes seawater drinkable in 30 minutes

    Access to clean, safe drinking water is a necessity that’s worryingly not being met in many parts of the world. A new study has used a material called a metal-organic framework (MOF) to filter pollutants out of seawater, generating large amounts of fresh water per day while using much less energy than other methods.

    NASA Perseverance rover and its epic Mars mission: Everything you need to know

    NASA's Perseverance rover hopes to answer our biggest burning question about Mars history: Did the red planet once host life? The dry, dusty Mars we know today was very different in the deep past. Humanity's latest rover is making a beeline for an area of Mars that was once home to a lake, a perfect place to look for signs of ancient microbes.

    This engineer published scientific papers using a Lego microscope

    For Yuksel Temiz, photographing extremely tiny subjects is just part of his job as a microelectronics engineer at IBM’s Zurich Research Laboratory. Temiz works on minuscule devices that use microfluidics: a type of tiny, liquid-based circuitry that, instead of using metal wires, directs the flow of liquid through hair-thin channels like a microscopic canal system.

    Falcon 9 launches final first-generation Dragon

    A SpaceX Falcon 9 lifted off March 6 and placed into orbit a Dragon spacecraft on the final flight of that version of the cargo vehicle. The Falcon 9 launched from Space Launch Complex 40 at Cape Canaveral Air Force Station at 11:50 p.m. Eastern. The Dragon spacecraft separated from the rocket’s upper stage in low Earth orbit nine and half minutes later.

    Researchers at the University of Queensland, Australia—claim solar efficiency breakthrough for flexible 'skin'

    The development of next-generation solar power technology that has potential to be used as a flexible ‘skin’ over hard surfaces has moved a step closer, thanks to a significant breakthrough at The University of Queensland. UQ researchers set a world record for the conversion of solar energy to electricity via the use of tiny nanoparticles called ‘quantum dots’, which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device.

    Oil and gas firms 'have had far worse climate impact than thought'

    The oil and gas industry has had a far worse impact on the climate than previously believed, according to a study indicating that human emissions of fossil methane have been underestimated by up to 40%. Although the research will add to pressure on fossil fuel companies, scientists said there was cause for hope because it showed a big extra benefit could come from tighter regulation of the industry and a faster shift towards renewable energy.

    Why the Cessna Is Such a Badass Plane

    In December of 1903, Wilbur and Orville Wright made history with their bi-plane contraption that managed to do the seemingly impossible: it gave man the ability to fly. The concept was so unearthly, in fact, that private aviation first took off not as a means of transportation, but as a sideshow of sorts. In those pioneer days, seeing a man use technology to overcome gravity was such a novelty that early aviators made their living mostly through exhibition flights.

    This Cloth Destroys Deadly Nerve Agents in Minutes

    In Omar Farha’s lab at Northwestern University, the chemist and his team are working on an unusual craft project in collaboration with the United States Army. They mix powders and liquids into a paint-like consistency, dip swatches of cotton fabric into the liquid, and then leave the beige cloth out to dry. Through this process, they are creating fabrics that can rapidly neutralize some of the deadliest poisons known to humankind: nerve agents.
