Astronauts Capture Dragon Loaded With New Science

Dragon Capture
The Dragon resupply ship is pictured just 10 meters away from the space station’s Canadarm2.

While the International Space Station was traveling overhead between  Australia and Papua New Guinea, NASA astronauts Mark Vande Hei and Joe Acaba captured the Dragon spacecraft at 5:57 a.m. EST using the space station’s robotic arm. Ground controllers will now send commands to begin the robotic installation the spacecraft on the station’s Harmony module. NASA Television coverage of installation will begin at 7:30 a.m. Watch online at

Dragon is carrying a Space Debris Sensor (SDS) that 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.

Also on board is NASA’s Total and Spectral Solar Irradiance Sensor, or TSIS-1, that 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.
