Mystery Doug LIVE Special - Thursday, May 21, 10 am PT / 1 pm ET

On Thursday, May 21, Doug is inviting students into his home for another LIVE, 20-minute science show. This show will be all about SPACE–including a special video cameo by astronaut Jessica Meir, who answered real student questions Doug sent to her while she was aboard the International Space Station! (Seriously!) Don't forget to vote at the end for the next question!
