SpaceX resupply truck Dragon on route to ISS for space research delivery

An experiment in space manufacturing and an enhanced study of solar energy are among the research currently heading to the International Space Station following Friday's launch of a SpaceX Dragon spacecraft at 10:36 a.m. EST.

Dragon lifted off on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida with more than 4,800 pounds of research equipment, cargo and supplies that will support dozens of the more than 250 investigations aboard the space station.

Research materials flying inside Dragon's pressurized area include an investigation demonstrating the benefits of manufacturing fiber optic filaments in a microgravity environment. Designed by the company Made in Space, and sponsored by the Center for the Advancement of Science in Space (CASIS), the investigation will attempt to pull fiber optic wire from ZBLAN, a heavy metal fluoride glass commonly used to make fiber optic glass. Results from this investigation could lead to the production of higher-quality fiber optic products for use in space and on Earth.

NASA's Total and Spectral Solar Irradiance Sensor, or TSIS-1, will measure the Sun's energy input to Earth. TSIS-1 measurements will be three times more accurate than previous capabilities, enabling scientists to study the Sun's natural influence on Earth's ozone, atmospheric circulation, clouds and ecosystems. These observations are essential for a scientific understanding of the effects of solar variability on the Earth system.

The Space Debris Sensor (SDS) will measure the orbital debris environment around the space station for two to three years. Once mounted on the exterior of the station, this one-square-meter sensor will provide near-real-time debris impact detection and recording. Research from this investigation could help lower the risks posed by orbital debris to human life and critical hardware.

This is SpaceX's 13th cargo flight to the space station under NASA's Commercial Resupply Services contract. Dragon is scheduled to depart the station in January 2018 and return to Earth with more than 3,600 pounds of research, hardware and crew supplies.

For more than 17 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 2,100 research investigations from researchers in more than 95 countries.

Two astronauts, cosmonaut return from five-month ISS mission
Dzhezkazgan, Kazakhstan (AFP) Dec 14, 2017
Two astronauts, from the US and Italy, and a Russian cosmonaut on Thursday landed in Kazakhstan after almost five months on the International Space Station, footage from the Russian space agency showed. American Randy Bresnik, Paolo Nespoli of Italy and Sergey Ryazanskiy of Russia landed on the Kazakh steppe at 2.37pm local time (0837 GMT) in a Soyuz MS-05 spacecraft. Over 139 days in s ... read more
