SPACE AND STONE: If you've got "Rosetta" in your name or title, you're likely having a great week. Back in August 2014, the Rosetta probe became the first spacecraft to ever be put into orbit around a comet, but it gets better: it successfully released the Philae spacecraft, which landed on that comet earlier this morning. (Vox gives a pictorial play-by-play.) And as if that wasn’t good enough, the learning company Rosetta Stone recently released Rosetta Stone Kids Reading in partnership with Lexia Learning. This collection of online and mobile reading products include 600 units of learning material and 50 activities and games covering phonological awareness, phonics, and more.
