Dr. Jim Green of NASA visited Burlington, Iowa in late August to mark an important milestone: the 30th anniversary of relocating a telescope to the brand new John Witte Observatory. The event was significant to Green because he used that telescope while attending Burlington High School.

Dr. Jim Green knew early on that he wanted a career in science because that was one of the subjects he was good at in school. He said he also enjoyed it, adding he was able to narrow his focus down a bit thanks to an astronomy class he took as a junior at Burlington High School.

The patch of bedrock where Curiosity drilled for its first sample lies in an ancient network of stream channels descending from the rim of Gale Crater. The bedrock also is fine-grained mudstone and shows evidence of multiple periods of wet conditions, including nodules and veins.
