Planetfest '21: To Mars and Back Again

Revisit the fun of Planetfest '21 on demand. 

Planetfests are a Planetary Society tradition of coming together to celebrate major space milestones. When NASA’s Perseverance rover, China’s Tianwen-1 lander, and the United Arab Emirates’ Hope orbiter all arrived at Mars in February 2021, we celebrated by hosting our first-ever all virtual version of the event:
