The road to space has been a rocky one for most spacecraft, and LightSail is no different. Challenges remain even with the May 20th launch of a test mission approaching. Embedded LightSail reporter Jason Davis checks in with the latest news. Emily Lakdawalla takes us to the Rosetta probe as Comet 67P closes on the sun. Bill Nye spent some quality time with President Barack Obama, and salutes the 25th anniversary of the Hubble Space Telescope. Bruce Betts and Mat Kaplan are back from defending the planet in Italy with yet another What’s Up segment.
