In this image from June 24, 2022, NASA astronauts Jessica Watkins and Bob Hines, part of NASA’s SpaceX Crew-4, work on the XROOTS space botany investigation, which used the International Space Station’s (ISS) Veggie facility to test soilless methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth and could enhance cultivation of plants in terrestrial settings such as greenhouses, contributing to better food security for people on Earth.

A team of roboticists from NASA’s Johnson Space Center in Houston have applied their expertise in making robots for deep space to designing a fully electric shape-changing submersible robot that will cut costs for maritime industries. Aquanaut, seen here during testing in the giant pool at Johnson’s Neutral Buoyancy Lab, opens its shell and turns its arms, claw hands, and various sensors to the job. NASA has a long history of transferring technology to the private sector. The agency’s Spinoff publication profiles NASA technologies that have transformed into commercial products and services, demonstrating the broader benefits of America’s investment in its space program. Spinoff is a publication of the Technology Transfer program in NASA’s Space Technology Mission Directorate (STMD). Learn more: NASA Space Robotics Dive…

The Sun’s rays begin to illuminate the Earth’s atmosphere as the International Space Station flew into an orbital sunrise 261 miles above Texas, as seen in this image taken by astronaut Bob Hines. The crew doesn’t just snap pretty pictures; the research aboard the station benefits humanity in numerous ways. This week, the 11th annual International Space Station Research and Development Conference runs through Thursday, July 28, 2022, in Washington. The full conference agenda is available online. NASA will provide live coverage of select panels from the conference on NASA Television, the NASA app, and the agency’s website. The event coincides with the publication of the 2022 edition of the International Space Station Benefits for Humanity, highlighting the advances in scientific knowledge on Earth, and…

利用高空气球改进天气数据

利用高空气球改进天气数据

ByNASA中文

Researchers at Arizona State University in Tempe are evaluating a small, lightweight, efficient 3D imaging sensor designed for weather forecasting on consecutive balloon flights made possible by NASA’s Flight Opportunities program. Called CubeSounder, the innovation could benefit future balloon flights and CubeSats by enabling state-of-the-art atmospheric sounding capabilities – a process in which sensors probe the sky vertically for details on temperature, moisture, and water vapor, revealing subtle changes in the Earth’s atmosphere. The first of two NASA-supported flight tests for the technology took place in April in Tucson on a Stratollite high-altitude balloon from Tucson-based World View Enterprises. In this image, World View’s Stratollite high-altitude balloon is inflated on the launch pad in Tucson, Arizona on April 9, 2022. Image Credit: World View Enterprises…

测试未来的飞机

测试未来的飞机

NASA and industry partners are working towards a future that sees aviation meet cleaner sustainability standards. To that end, new designs for the airplanes of tomorrow, such as the Transonic Truss-Braced Wing (TTBW) concept shown in this image from 2021, are being tested by researchers and engineers. The TTBW is essentially a classic tube-and-wing passenger aircraft whose wings are extremely long and thin – so much that they need a little help to hold them up. By narrowing the thickness of the wings and extending their length, drag is reduced, and 5-10 percent less fuel is burned than comparable narrowbody aircraft. This image was created using data from a computational fluid dynamics simulation – essentially a virtual wind tunnel test. The red and orange areas…

跨音速桁架式机翼可能有助于减少燃料消耗

ByNASA中文

Instrumentation technician Michael Hodgins performs installation measures on the trans-sonic truss-braced wing (TTBW) model at Langley Research Center’s 14×22 subsonic wind tunnel. The unique design of the aircraft’s wings reduces drag during flight, which in turn reduces fuel consumption by up to 10 percent. This concept is part of an ongoing initiative by NASA, industry partners, and academia to make the future of aviation more environmentally friendly through the Sustainable Flight National Partnership (SFNP). The SFNP will expand research for sustainable aviation by developing and testing new technologies for aircraft, new automation tools for greener and safer airspace operations, and sustainable energy options for aircraft propulsion. The TTBW will undergo a variety of aerodynamic testing as researchers continue to test key flight components such as…
