MIT engineers fly a Star Trek-inspired plane without any moving parts

MIT engineers fly a Star Trek-inspired plane without any moving parts

Today, Barrett and his colleagues have taken advantage of advances in electronics and computer modeling systems to fine-tune and significantly scale down the components required to create ionic winds. It listed possible military applications including the development of silent drones and aircraft, and engines with no infrared signal and thus impossible to detect. Consulte Mais Informação

Elon Musk smokes pot. Nasa to review SpaceX workplace culture

NASA's Office of Safety and Mission Assurance will lead the probe, which the space agency's associate administrator William Gerstenmaier has said will be "pretty invasive". These launches also allowed for the construction of the International Space Station - the largest structure in space, that's now home to a revolving crew of astronauts from all around the world, conducting important experiments that continue to advance our knowledge of the cosmos.

NASA Selects Martian Lake-Delta System For Landing Of Mars 2020 Rover

NASA Selects Martian Lake-Delta System For Landing Of Mars 2020 Rover

NASA and the European Space Agency plan to eventually retrieve these samples and bring them back to Earth. 'Getting samples from this unique area will revolutionize how we think about Mars and its ability to harbour life'. NASA assured that mission engineers have reduced the landing zone of Mars 2020 to 50 percent smaller than Curiosity 's in 2012 at Gale Crater. The sites of greatest scientific interest led NASA to add a new capability called Terrain Relative Navigation (TRN). Consulte Mais Informação

NASA picks 'coveted' landing site for Mars 2020 rover

The landing site of Jezero Crater is different because of its abundant carbonate rocks and what they can hopefully reveal about early habitability on Mars, NASA said. When the landing site search began, mission engineers already had refined the landing system such that they were able to reduce the Mars 2020 landing zone to an area 50 percent smaller than that for the landing of NASA's Curiosity rover at Gale Crater in 2012.

Astronomers Find Super-Earth Orbiting the Nearby Barnard's Star

Astronomers Find Super-Earth Orbiting the Nearby Barnard's Star

The results of the study are published in the journal Nature . "On the contrary, when the star approaches us, the light becomes more energetic and bluish", says Ribas. In addition, the new find provides further evidence that planets are almost ubiquitous around red dwarf stars, said Ignasi Ribas, an astronomer and director of the Institute of Space Studies of Catalonia in Spain , who led the work.

Scientists confirm massive impact crater beneath Greenland's ice

Scientists confirm massive impact crater beneath Greenland's ice

It is one of the 25 largest known impact craters on Earth, and the first found under any of our planet's ice sheets. The crater is less than 3 million year old and was formed by a huge half-mile wide iron meteorite. Chemical analysis performed at Cardiff University allowed researchers to paint a picture of the type of object capable of causing the amount of destruction by measuring the sediment from a river that drains straight through the glacier, and looked for signs of metals that would ...

Delhi's air quality 'improves significantly' but still far from safe: Authorities

He said that implementing the ban would be hard as it is not possible to distinguish between diesel and other fuelled vehicles. On Wednesday, the PM2.5 - particles in the air with a diameter of less than 2.5 micrometres - level was recorded at 175, while the PM10 - particles in the air with a diameter of less than 10 micrometres - was recorded at 280 in Delhi, according to the data by the Central Pollution Control Board .
