About three years ago I had a project to design and build retro-reflecting targets for the Advanced Video Guidance Sensor, a device that measures how far away the targets are and how they&#8217;re oriented. If you know that and you know how the targets are mounted to a satellite, you know the distance to the satellite and which way the satellite is pointing. That&#8217;s the kind of stuff you need to know if you&#8217;re going to dock two spacecraft on orbit without a pilot flying one of them.<\/p>\n<p>And as it happens, DARPA, Boeing and NASA are doing just that for the <a href=\"http:\/\/www.darpa.mil\/orbitalexpress\/\">Orbital Express mission<\/a>. Orbital Express has two satellites that will move away from each other, re-dock, and transfer fluid to demonstrate on-orbit satellite refueling. OE is using AVGS and our targets.<\/p>\n<div class=\"centerimage\"><img decoding=\"async\" src=\"\/images\/2007\/Mar\/oetargets.jpg\" alt=\"OE targets\" title=\"They're so tiny!\" \/><\/div>\n<p>Ah, there our targets are, nicely circled in red. Anyway, Orbital Express launched on March 8th. Today I found out that DARPA has released <a href=\"http:\/\/www.darpa.mil\/orbitalexpress\/mission_updates.html\">footage of the two satellites on orbit<\/a> as viewed from the camera arm. If you <a href=\"http:\/\/www.darpa.mil\/orbitalexpress\/video\/OEDMSSurvey3-28-07.mpeg\">watch the video<\/a>, at the very beginning you can see one of our targets &#8212; it&#8217;s the bright white cylinder in the top right corner. At 00:26 you can see one of the targets move from the left side of the video to the right and another come into the field of view. At 02:25 to 02:27 you can see a very overexposed version of the smaller target cluster.<\/p>\n<p>Like many kids, I dreamed of being an astronaut. One night in high school, while I waited for my parents to pick me up, I lay down in the grass and stared up past the brick wall next to me and into space. &#8220;I&#8217;ll see you one day,&#8221; I whispered to the moon. Later I realized that I would never be an astronaut, and how the difficulties of going to space meant I would likely never leave the ground. For a boy who dreamed of the stars, having something you held in your hand, something you helped shepherd from idea to reality, now orbiting the Earth is the next best thing.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I don&#8217;t normally talk about work here, since that&#8217;s a good way to get Dooced, but this is too cool for me not to share.
