Thermoelectric device harnesses cold of space to power LED light at night

Thermoelectric device harnesses cold of space to power LED light at night

Science
Sept. 13 (UPI) -- Engineers have developed a thermoelectric device that works in the dark of night, harnessing the cold of space and turning it into electricity to power an LED light. The affordable technology works without any heat inputs. "Remarkably, the device is able to generate electricity at night, when solar cells don't work," Aaswath Raman, an assistant professor of materials science and engineering at the University of California, Los Angeles, said in a news release. "Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed." Batteries can be installed on solar cells to store energy harvested during the day for use at night, but the add-on is costly. Otherwise,...
Unmanned Soyuz docking at International Space Station aborted; another try planned

Unmanned Soyuz docking at International Space Station aborted; another try planned

Science
Aug. 24 (UPI) -- An unmanned Russian Soyuz MS-14 spacecraft aborted a docking with the International Space Station and another attempted is planned no earlier than Monday, space officials said Saturday. The spacecraft, which was maneuvered by a robot called Skybot F-850, was aborted at 1:36 a.m. EDT, NASA said in a blog post. After liftoff Wednesday night, the spacecraft made 34 orbits of Earth en route to its anticipated docking. Instead it came within roughly 330 feet from the ISS. The docking could not be attempted manually because there wasn't a necessary system on board the Soyuz, a NASA announcer said during the live broadcast. There is no threat to the International Space Station and its crew, according to Russian space agency Roscosmos in a report by state-run TASS. The Soyuz is...

Nasa said to be investigating first allegation of a crime in space

Science
Nasa is reported to be investigating a claim that an astronaut accessed the bank account of her estranged spouse from the International Space Station, in what may be the first allegation of a crime committed in space.Anne McClain acknowledges accessing the account from the ISS but denies any wrongdoing, the New York Times reports.Her estranged spouse, Summer Worden, reportedly filed a complaint with the Federal Trade Commission.Ms McClain has since returned to Earth.The astronaut told the New York Times through a lawyer that she was merely making sure that the family's finances were in order and there was enough money to pay bills and care for Ms Worden's son - who they had been raising together prior to the split."She strenuousl...

Spaceplane gets a ride for space station trips

Science
The Dream Chaser spaceplane, which will ferry cargo to the International Space Station (ISS), now has a rocket to launch on.Sierra Nevada, the private company that builds the spaceplane, has chosen the Vulcan rocket as its ride into orbit.The company hopes to start launching missions by 2021, to deliver supplies to astronauts on the ISS.Neither the Dream Chaser vehicle, nor the Vulcan rocket, has yet flown to space.Sierra Nevada was recently awarded the contract by Nasa to re-supply the ISS.It joins two other private companies that already ship cargo and experiments to the station - SpaceX and Orbital ATK.The Vulcan Centaur rocket, built by United Launch Alliance (ULA), is currently in production.Under its Nasa contract, Dream Ch...
