10/10/2017 – Ephemeris – Ada Lovelace Day

October 10, 2017 1 comment

Ephemeris for Ada Lovelace Day, Tuesday, October 10th. The Sun will rise at 7:51. It’ll be up for 11 hours and 14 minutes, setting at 7:06. The Moon, 2 days before last quarter, will rise at 11:01 this evening.

Ada Lovelace Day is a day set aside to celebrate women in STEM, Science, Technology, Engineering and Math. Ada Augusta King, Countess of Lovelace, born in 1815 is considered the world’s first computer programmer, writing a program on Jacquard loom punch cards for Charles Babbage’s Analytical Engine. Unfortunately the Analytical Engine never made it past the planning stage.

The recently completed incredibly successful Cassini Mission mission had three women in top roles: Project scientist, Linda Spilker; Spacecraft Operations Team Manager, Julie Webster; Imaging Science Subsystem Principle Investigator, Carolyn Porco, plus many more. STEM fields are still male dominated but lets encourage the girls to enter them too.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
