Diffractive sails on spacecrafts

A Rochester Institute of Technology (RIT) researcher is taking solar sailing to the next level. He proposes replacing reflective metallic sails with diffractive metafilm sails. The new materials could be used to steer reflected or transmitted photons for near-Earth, interplanetary and interstellar space travel. Grover Swartzlander is leading an exploratory study supported by phase one … Continue reading Diffractive sails on spacecrafts

Diverse minerals found in Mars

#Mars #NASA #Curiosity #space #life #planet #minerals Curiosity rover, the NASA's rover on Mars, has found a variety of minerals on the red planet. These layers of rocks are predicted to have been deposited about 3.5 billion years ago, coinciding with a time on Earth when life was beginning to take hold. In fact, early … Continue reading Diverse minerals found in Mars

Colorful skies over New York/North Carolina

#NASA #air #experiment #NewYork #Sky #color #space An experiment conducted by NASA might color the skies over the US mid-Atlantic coast with bluish green and red clouds. The experiment was scheduled for Sunday evening, in which NASA seeks to learn more about charged particles at the Ionosphere (Earth's top most atmosphere layer). A small rocket … Continue reading Colorful skies over New York/North Carolina

NASA’s Deep Space Lunar Gateway

#NASA #Space #Moon #DeepSpaceGateway #astronauts #Mars #science NASA aims to have a Deep space Gateway up and running in the 2020s. The gateway will be located on Moon and have a crew habitat, a propulsion module and an airlock. However, the gateway will be occupied intermittently, rather than continuously like the ISS. The gateway will … Continue reading NASA’s Deep Space Lunar Gateway

Going to be hit by an Asteroid?

#space #meteor #asteroid #NASA #Sentry #Collision #TauridStream The Taurid meteoroid stream produces a low number of meteors and a meteor shower usually in October and November. The branch includes asteroids having diameters more than 200 meters, and it is unclear if any of them has a trajectory collision with Earth, although no such situation has … Continue reading Going to be hit by an Asteroid?

NASA to build a satellite with ISRO

#NASA #ISRO #satellite #Earth #imaging #NISAR #space NASA and ISRO will be teaming up to build the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, an Earth imaging satellite. The project cost will be close to $1.5 billion. NISAR is the first big collaboration between NASA and ISRO, certainly on RADAR but just in general as well. … Continue reading NASA to build a satellite with ISRO

‘Bubble’ around Earth

#Earth #space #radiations #NASA #VLF #barrier #radiotransmissions NASA has spotted a man-made barrier around the Earth that prevents high-energy space radiation from reaching the planet. VLF (Very Low Frequency) radio communications interact with particles in space, affecting how and where they move. These interactions can create a barrier around the Earth against natural high energy … Continue reading ‘Bubble’ around Earth
