Tomorrow Sara Sabry becomes our second Citizen Astronaut to go to Space. When she does, she adds to a growing trend of new explorers. But these trailblazers aren’t exploring some dark, unknown border on a map. They explore what it is to be human. What it means to be connected. What it feels like to bring hope to a new generation of explorers whose journeys will permeate all peoples of this place we all call home. She also continues the trend started by our first citizen astronaut, Katya Echazarreta. To write a letter to those that come next. So, to you, the next citizen astronauts. Here’s Sara in her own words.
