The National Aeronautics and Space Administration (NASA) plans to send its first robotic spacecraft to the Sun in 2018.We live in the sun’s atmosphere! Over the next several years successive Venus gravity assist (VGA) maneuvers gradually lower the perihelia to ~9.5 RS, by far the closest any spacecraft has ever come to the Sun. Scientists do not understand why the Sun’s surface or photosphere is nowhere near as hot as its atmosphere or corona.”This is going to be our first mission to fly to the Sun”, said Eric Christian, a NASA research scientist at Goddard Space Flight Centre, according to PTI.According to NASA, the surface temperature of the Sun is only about 5,500 degrees Celsius. Chile floods: Drinking water returns to capital Santiago
Aguas Andinas, the company that provides Santiago’s water supply, said the ongoing downpours were making repairs hard . Officials had said the water supply from the Maipo river had to be cut until the water flowed clear. NASA has designed an 11.4 centimetres carbon-composite shield, which is created to withstand temperatures outside the spacecraft of 1,370 degrees Celsius.”We can’t get to the very surface of the sun, but the mission will get close enough to answer important questions”. Solar Probe Plus will revolutionize our knowledge of the physics of the origin and evolution of the solar wind.Specialists indicated that this unstable corona, the big hole in the heart of the Sun, is thought to be cooler compared to the rest of the star’s atmosphere. Astronomers are expecting to gather interesting information about Sun’s corona.A new study developed by the National Academy of Sciences has suggested that if we do not receive an advance warning, a massive solar weather event could cause damages of at least two trillion dollars in the U.S. alone.Further NASA scientists are also looking for an answer to the question of how is solar wind gets its speed. Chrissy Teigen Napped Through Casey Affleck’s Acceptance Speech
Earlier this year she decided she DGAF about “convention” at the Golden Globes and chose to sit down on the red carpet. Eventually, I guess Chrissy just couldn’t take it any more. “No one will ever know.” she said. The sun and its atmosphere are made of plasma – a mix of positively and negatively charged particles which have separated at extremely high temperatures, that both carries and travels along magnetic field lines. “We can’t get to the very surface of the sun”, he added while affirming the importance and significance of this mission. Usually, solar flares, mass ejections and strong solar winds emanate for Sun’s corona.Third, NASA hopes the probe will identify the causes of the Sun’s intermittent emissions of high-energy solar energetic particles, which are potentially risky to unprotected satellites, spacecraft, and astronauts.The sun probe will also have special heat tubes called thermal radiators that will radiate heat coming in so that heat-sensitive instruments are not damaged.If these protections work as expected, the instruments in the probe will stay at room temperature, Christian concluded. “Data will be key to understanding and, perhaps, forecasting space weather”, said Nasa. Third-Party iPhone Screen Repair No Longer Voids Warranty, Apple Says
It’s much cheaper to take your device to a third-party repairer, or to just buy new a display off of eBay and fit it yourself. Apple has made a behind-the-scenes change to its views on third-party screen fix .
