Leonard Reiffel, a member of Phillips' science staff, recommended on 20 June that considering the uncertainty about an astronaut's ability to work in onesixth gravity, "an uncrowded time line" would be "more contributory to the advance of science than attempting to do so much that we do none of it well".
