NASA Probe Sees Solar Wind Decline
The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind. Now hurtling toward interstellar space some 17.4 billion...

NASA's Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite deployed its 100-square-foot polymer sail in low-Earth orbit and is operating as planned. Actual deployment occurred on Jan. 20 at 10 p.m. EST and was confirmed today with beacon packets data received from NanoSail-D and additional ground-based satellite tracking assets. In addition, the NanoSail-D orbital parameter data set shows an appropriate change which is consistent with sail deployment.
"This is tremendous news and the first time NASA has deployed a solar sail in low-Earth orbit," said Dean Alhorn, NanoSail-D principal investigator and aerospace engineer at the Marshall Center. "To get to this point is an incredible accomplishment for our small team and I can't thank the amateur ham operator community enough for their help in tracking NanoSail-D. Their assistance was invaluable. In particular, the Marshall Amateur Radio Club was the very first to hear the radio beacon. It was exciting!"
It is estimated that NanoSail-D will remain in low-Earth orbit between 70 and 120 days, depending on atmospheric conditions. NanoSail-D is designed to demonstrate deployment of a compact solar sail boom technology. This research demonstration could lead to further advances of this alternative solar sail propulsion and the critical need for new de-orbit technologies. This ejection experiment also demonstrates a spacecraft’s ability, like the Fast, Affordable, Science and Technology Satellite, or FASTSAT, to eject a nano-satellite from a micro-satellite, while avoiding re-contact with the primary satellite.
"This is a significant accomplishment for both the FASTSAT and NanoSail-D projects. This accomplishment validates that we've met another of our primary mission objectives -- successfully ejecting a nanosatellite from an orbiting microsatellite," said Mark Boudreaux, FASTSAT project manager at the Marshall Center. "This is another significant accomplishment for our inter Agency, Industry and Governmental FASTSAT-HSV01 partnership team."
