This amazing feat of engineering has become surprisingly routine — we humans have gotten to the point where launching a vehicle into space to carry out an experiment or deliver a satellite into orbit no longer inspires awe and wonder. Sounding rockets are commonly used as sub-orbital research platforms. In this case, one of the experiments on the mission was a test of how well DNA molecules can survive the temperatures involved in plummeting back through Earth’s atmosphere.

Survey for science bloggers

Paige Brown Jarreau is doing a PhD in science communication at Louisiana State University, and part of her research focuses on science bloggers. She’s surveying science bloggers about their blogging practices to gather data for her research. Since I know some of the regular readers of Inspiring Science are also science bloggers in their own right, I thought I’d try to help Paige by linking to her survey in case some of you want to participate. She’s also offering a $7.00 gift voucher from Amazon to the first 200 respondents.
