Science Friday and 500 Women Scientists are hosting their very own livestream as the Mars 2020 mission completes its trip to the Red Planet! We’ll talk about all kinds of space topics – searching for far-away galaxies, satellites and other space junk orbiting the Earth, and all things Mars news. Join the conversation online by using the hashtags #BreakthroughFestival and #CountdownToMars. We encourage attendees to watch the Breakthrough videos featuring Burçin Mutlu-Pakdil and Kayla Iacovino in advance of the event: The Galaxy Hunter and The Volcano Trekker. All Breakthrough videos are family friendly!
