The Upper Free Flyer (NORAD ID: 43763<\/a>) is a large structure at approximately 1,000kg and the Lower Free Flyer is approximately 260kg (NORAD ID: 43760<\/a>). Each Free Flyer hosts one of our 16m2 aluminised kapton sail which was set to deploy 24 hours after launch.<\/p>\n The systems were standalone isolated systems with no communications so we don\u2019t have any telemetry confirmation. Drag parameters from the TLEs are indicative of a successful deployment, but far from definitive. We\u2019re therefore waiting for them to become optically visible in northern latitudes in the next couple of weeks. Based on the experience with our InflateSail mission, we\u2019d expect these objects to be quite bright to the naked eye if the sails have deployed successfully. InflateSail was 10m2 and (initially) transparent with a +4.2 mag, whereas these sails are 16m2 and metalised so could well flare brightly.<\/p>\n Any observations that could be made by the community of either of these objects would be greatly appreciated and they should make for interesting targets.<\/p>\n We are also the team leading the RemoveDebris mission (NORAD ID: 43510) launched from the ISS last year We have a 9m^2 dragsail installed on this mission too which is planned for deployment next month. Similarly, this should make quite a big change to the brightness of the satellite which could make for some interesting observations.<\/p>\n Best Regards, Seesat-l mailing list http:\/\/mailman.satobs.org\/mailman\/listinfo\/seesat-l<\/a><\/p>\n Track of Upper Free Flyer https:\/\/n2yo.com\/?s=43763&df=1&live=1<\/a><\/p>\n Track of Lower Free Flyer https:\/\/n2yo.com\/?s=43760&df=1&live=1<\/a><\/p>\n Get The Details…<\/a><\/p>\n m5aka<\/p>\n AMSAT-UK<\/p>\n","protected":false},"excerpt":{"rendered":" The solar sails on the SSO-A mission \u201cFree Flyer\u201d deployers, launched December 3, 2018 with many amateur radio satellites, are believed to have deployed and may now be quite bright to the naked eye.<\/p>\n Ben Taylor<\/strong> writes:<\/p>\n I represent a team from the University of Surrey in the UK; we have been developing and flying drag de-orbit sails with our first successful demonstration on our InflateSail mission in 2017.<\/p>\n Two dragsail systems were installed on the \u201cFree Flyer\u201d deployers used on the SSO-A launch from December 3, 2018 Continue reading
