“I wish that every country would follow in the footsteps of the U.S. and now China.”
–Statement by Frédéric Moynier, a cosmochemist at the Paris Institute of Planetary Physics, regarding China’s sharing of lunar samples from its 2020 Chang’e-5 mission. Seven institutions in six countries now have access to these samples, including two institutions in the United States. Unfortunately, the sample sharing goes only one way because the US Congress bans the sharing of space samples and technology with China.
