President and Executive Director, Center for the Advancement of Science in Space and former NASA astronaut. 

Describe a typical day:

No typical day. Conduct meetings to manage CASIS, interface with external partners and stakeholders, and communicate the importance of the mission to the industry and public. 

Top tip from Greg for those interested in a similar career:

Do what you love and do it well. Don’t choose a path to “get somewhere else.” I suggest choosing paths that you love that can lead to additional paths you desire. Always work hard. Always be true to yourself. 

Being a strong supportive follower can lead to leadership positions. Demonstrate and earn your way with hard work and support for the mission of your organization, whatever it may be.
