[i]At 2:47 Eastern time on July 23, the big moment cameāfour cobalt-alloy booms extended like a tape measure, pulling with them four triangular Mylar sails. The whole deployment took about three minutes. Soon, LightSail 2 will begin to live up to its name. "We use the term boom just like on a sailboat, to hold the sails out, because we're twisting relatively fast in Earth orbit," explained Bill Nye, former host of Bill Nye the Science Guy and now CEO of the nonprofit Planetary Society, to the press before launch. "We go edge on toward the sun, twist 90 degrees, go face on and get a full push like a sailboat going downwind, building orbital energy. [We] then twist again on the night side of the Earth and twist on the day side, over and over."[/i]
