Submission + - India Test Fires First Scramjet Engine (thehindu.com)

William Robinson writes: India test fired Advanced Technology Vehicle (ATV), a research rocket with a solid booster carrying advanced scramjet engines, which is Air Breathing Propulsion System that uses hydrogen as fuel and oxygen from the atmosphere air as the oxidiser. Since 70 per cent of the propellant mass is oxidiser, using oxidiser directly from air makes flights significantly cheaper. Also air breathing technique makes is less prone to failure because it uses less moving parts. India is fourth country to test this technology after US, Russia and EU.

Submission + - Accessing Torrent Site Will Invite Imprisonment In India (indiatimes.com)

William Robinson writes: According to recent reports, a visit a torrent website from within India , you might be committing a crime, one that earns a Rs 3 lakh fine (approx US$ 4400 ) and 3 years in prison. The ban extends to looking at "a torrent file, or downloading a file from a host that may have been banned in India, or even for viewing an image on a file host like Imagebam". Earlier, the Government of India had blocked many torrent sites, and there used to be simple message implying the URL is blocked. But legal warning is a recent development, which says, "This URL has been blocked under the instructions of the Competent Government Authority or in compliance with the orders of a Court of competent jurisdiction. Viewing, downloading, exhibiting or duplicating an illicit copy of the contents under this URL is punishable as an offence under the laws of India, including but not limited to under Sections 63, 63-A, 65 and 65-A of the Copyright Act, 1957 which prescribe imprisonment for 3 years and also fine of upto Rs. 3,00,000/-. Any person aggrieved by any such blocking of this URL may contact at urlblock@tatacommunications.com who will, within 48 hours, provide you the details of relevant proceedings under which you can approach the relevant High Court or Authority for redressal of your grievance"

Submission + - NASA TV to Air Spacewalk Live on August 19 (spacecoastdaily.com)

William Robinson writes: NASA Television will be bringing to viewers around the world live coverage Friday, Aug. 19, as two NASA astronauts install a new gateway for American commercial crew spacecraft at the International Space Station. Walking in space alone poses a threat to the astronauts performing their duty, but the new mission of installing a dock into the ISS adds to the level of difficulties that astronauts will need to survive in order to perform their duty. Coverage will begin at 6:30 a.m. EDT Aug. 19, on NASA TV and the agency’s website, with the spacewalk scheduled to begin at 8:05 a.m. Leading up to the spacewalk, NASA TV will air a briefing from the agency’s Johnson Space Center in Houston at 2 p.m. Monday, Aug. 15, during which station and commercial crew experts will discuss the process and significance of installing and connecting the first of two international docking adapters (IDAs) that will be used for the future arrivals of Boeing and SpaceX commercial crew spacecraft. Not an event to miss.

Submission + - SPAM: NASA Releases Video Of Plasma Rain On Sun's Surface

William Robinson writes: NASA has released another breathtaking video of plasma rain on the solar surface. The mid-level solar flare was captured using Interface Region Imaging Spectrograph, or IRIS. As the video continues, solar material cascades down to the solar surface in great loops, a flare-driven event called post-flare loops or coronal rain. This material is plasma, a gas in which positively and negatively charged particles have separated, forming a superhot mix that follows paths guided by complex magnetic forces in the sun’s atmosphere.

Submission + - Solar Cells Converting Co2 Into Hydrocarbon Fuel Discovered. (nextbigfuture.com)

William Robinson writes: Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy. This artificial leaf delivers syngas, or synthesis gas, a mixture of hydrogen gas and carbon monoxide. Syngas can be burned directly, or converted into diesel or other hydrocarbon fuels. The discovery opens up possibilities of clean reusable energy.

Submission + - Cheaper Flow Batteries Using Vitamins Discovered (natureworldnews.com)

William Robinson writes: Scientists from Harvard University have discovered how to create flow batteries using organic molecules inspired by vitamin B2, which helps store energy from food in the body. With a few tweaks to the original B2 molecule, the scientists discovered a new group of organic molecules that make good candidates for alkaline flow batteries. The result of the discovery was a redox flow battery that demonstrates an open-circuit voltage approaching 1.2V, with a current efficiency of 99.7 percent and a capacity retention over 99.98 percent per cycle.

Submission + - UDS Releases Images. 250,000+ Galaxies Found in Deep Space. (wired.co.uk)

William Robinson writes: The UDS Project (Ultra Deep Survey), part of UKIRT Infrared Deep Sky Survey, have recently released the final data providing spectacular infrared images of the distant Universe have provided astronomers with the deepest view ever obtained. The UDS mapped a total area four times the size of full moon and detected over 250,000 galaxies, including several hundred observed within the first billion year after Big Bang. This was done since 2005 by observing the same patch of sky repeatedly, obtaining more than 1,000 hours of exposure time and utilizing the power of infrared to provide the deepest view ever obtained over a large area in the sky,
