Those educational satellites, Max Valier Sat and Venta 1, were developed with the aid of German-based OHB System and launched by an Indian PSLV rocket. (Seattle-based Spaceflight played a role in launch logistics.)<\/p>\n<p>In a statement issued today, Breakthrough Starshot said the Sprites are still attached to the nanosatellites and are \u201cperforming as designed.\u201d The Sprite radio communication system is in contact with ground stations in California and New York, as well as with amateur radio enthusiasts around the world.<\/p>\n<p>The Sprite concept is the brainchild of Breakthrough Starshot\u2019s Zack Manchester, who came up with the idea for super-miniaturized space probes back in 2011, in connection with the crowdfunded KickSat space mission. Researchers at Cornell University constructed the chips for this summer\u2019s test.<\/p>\n<p><iframe id=\"twitter-widget-0\" scrolling=\"no\" frameborder=\"0\" allowtransparency=\"true\" allowfullscreen=\"true\" class=\"\" style=\"position: absolute; visibility: hidden; width: 0px; height: 0px; display: block; flex-grow: 1;\" title=\"X Post\" src=\"https:\/\/platform.twitter.com\/embed\/Tweet.html?creatorScreenName=b0yle&amp;dnt=true&amp;embedId=twitter-widget-0&amp;features=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%3D%3D&amp;frame=false&amp;hideCard=false&amp;hideThread=false&amp;id=890218055510446083&amp;lang=en&amp;origin=https%3A%2F%2Fwww.geekwire.com%2F2017%2Fbreakthrough-starshot-tests-worlds-smallest-space-probes-interstellar-mission%2F&amp;sessionId=ff0cdf8cf151252df5c7a39b54b7dbee8997546d&amp;siteScreenName=geekwire&amp;theme=light&amp;widgetsVersion=6a3ad42b224df%3A1778106238597&amp;width=550px\" data-tweet-id=\"890218055510446083\"><\/iframe><\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\" data-twitter-extracted-i1782802298856580547=\"true\">\n<p lang=\"en\" dir=\"ltr\">#StarChips in space!
