- Statement on fossils sent to space - I hear the concerns raised by the scientific community, which highlight the need for renewed engagement around the processes and permissions to use fossils and heritage artifacts for the public engagement in science. I strongly value the role of collaboration in science and the connection of these fossils to the greater story of humanity. The decision to send fossils of Homo naledi and Australopithecus sediba into sub-orbital space was the result of careful consideration and in-depth discussions with guiding and regulatory agencies. All the necessary permissions and permits were acquired, and great care was taken to ensure the safety of the fossils, which returned from the brief flight undamaged and intact and are now in South Africa. As a life-long scientist, I know we are at our best when we challenge one another to continue to grow and reflect, and I remain committed to ongoing dialogue and a lifetime of learning and growth.
