Engineers install heat shield on NASA's Parker Probe

Engineers install heat shield on NASA's Parker Probe

Science
July 6 (UPI) -- For the first time in months, the Parker Solar probe is fully integrated. Engineers have reinstalled the spacecraft's next-generation heat shield, NASA announced this week. For NASA's Parker Solar Probe, a spacecraft tasked with studying the sun, protection from extreme heat is obviously essential. The Thermal Protection System will provide that essential shielding. The protective layer was installed last fall but was removed shortly afterwards. In the months since, the shield and spacecraft have been subjected to a series of intensive tests. On its mission to study the sun's corona, the probe will fly within 4 million miles of the sun. The outside of the heat shield will reach 2,500 degrees Fahrenheit, but its insides, instruments included, will never get hotter than 85 ...
NASA engineers use gold to redirect excess heat from James Webb Telescope

NASA engineers use gold to redirect excess heat from James Webb Telescope

Science
June 5 (UPI) -- Engineers at NASA have found a way to redirect excess heat from the James Webb Telescope's most sensitive instruments. The telescope's four instruments are contained within the integrated science instrument module, or ISIM, which sits behind the array's main mirror. These sensitive instruments could be damaged or disrupted by excess heat, so scientists had to find a way to redirect thermal energy away from the ISIM. As detailed in a mission update published Tuesday by NASA, engineers are currently installing gold baffles that will channel thermal radiation away from the instruments and out into space. Gold also helps the telescope's mirrors direct infrared light toward the ISIM. "Gold has a very high reflectivity in the infrared spectrum range, so it is ideal for directin...
NASA engineers teach Mars rover Curiosity to drill again

NASA engineers teach Mars rover Curiosity to drill again

Science
May 18 (UPI) -- Engineers at NASA's Jet Propulsion Laboratory are preparing to add percussion to an improvised drill technique already being used by the Curiosity rover on Mars. Curiosity and its drill haven't had a full range of motion since 2016 when one of the drill's motors short circuited. Over the last year, engineers have developed a workaround drilling technique called Feed Extended Drilling, or FED, which uses the rover's robotic arm to direct and push the drill into the ground as the drill bit spins. In February, Curiosity used the FED technique to once again drill into the Martian surface. The effort failed to yield a rock sample, but it was still a partial success, producing data that allowed scientists to fine-tune the method back in the lab. Now, engineers are preparing to ...
1,600 IT workers and engineers denied UK visas

1,600 IT workers and engineers denied UK visas

Science
More than 1,600 IT specialists and engineers offered jobs in the UK were denied visas between December and March, BBC News has learned. They were denied because the number applying exceeded the monthly limit allowed to enter the UK.Critics argue that the immigration policy will hamper the government's efforts to develop a high-tech economy.The government said it was important that employers look to recruit from the UK before looking overseas.The figures were obtained by the Campaign for Science and Engineering (Case).Case's executive director, Dr Sarah Main, said that job offers in areas where there were clear shortages, such as science and engineering, should be exempt from the Home Office cap."The tragedy is that this policy doesn't work for anyone: the...
Female engineers set for success

Female engineers set for success

Science
Fewer than one in 10 engineers in the UK are female - the lowest percentage in Europe, according to the Women's Engineering Society. Latvia, Bulgaria and Cyprus lead with nearly 30%. Here, two pioneering female engineers at Oxford University explain what drives them.Priyanka Dhopade was named as one of the top 50 Women in Engineering Under 35 in 2017, as chosen by the Women's Engineering Society. She grew up in Canada, where she studied for a degree in aerospace engineering. She completed a PhD at Monash University in Melbourne before moving to Oxford in 2013.As a child I was very interested in aeroplanes, and how things fly in space - I wanted to be an astronaut. My parents suggested engineering, because it's quite practical. I could use my enthusiasm and my skills to do something that's ...
