Corporate Vice President, Sierra Nevada Corporation's Space Systems
We’re back at Space Symposium for a conversation with SNC’s Mark Sirangelo, leader of that company’s effort to build the Dream Chaser. We’ll also hear a few moments of Bill Nye’s session at the annual gathering as he hosted Bernard Foing and Amy Mainzer. Emily lets us sample her “What’s Up in the Solar System” May roundup. Bruce Betts helps Mat Kaplan feel better about missing the transit of Mercury.
What is the date of the next Mercury transit of the Sun as seen from Earth after the May 9, 2016 transit?
The answer will be revealed next week.
Question from the week before:
When was the first recorded observation of Mercury’s transit across the sun, and who made that observation?
The first well-documented observation of Mercury’s transit across the sun was made on November 7, 1631 by Pierre Gassendi, though it may have happened hundreds of years earlier when Ibn Bajjah saw something cross the star.
