Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate
Lori Glaze, director of NASA’s Planetary Science Division

Principal investigator of the selected mission

Hundreds of pounds of rocks and dirt taken from the lunar surface are stored at Johnson Space Centre in Houston, and Nasa lab workers are preparing to hand over some of the pristine samples to scientists for study.

Nine US research teams will get a chance to examine the geological treasures – brought back between 1969 and 1972 – over the next year.
