Roosa spent almost two days alone aboard ''Kitty Hawk'', performing the first intensive program of scientific observation from lunar orbit, much of which was intended to have been done by Apollo 13.{{sfn|Chaikin 1995|pp=361–364}} After ''Antares'' separated and its crew began preparations to land, Roosa in ''Kitty Hawk'' performed an SPS burn to send the CSM to an orbit of approximately {{convert|60|nmi}}, and later a [[plane change]] maneuver to compensate for the rotation of the Moon.{{sfn|Mission Report|p=9-19}}

Roosa took pictures from lunar orbit. The Lunar Topographic Camera, also known as the Hycon camera, was supposed to be used to image the surface, including the Descartes Highlands site being considered for Apollo 16, but it quickly developed a fault with the shutter that Roosa could not fix despite considerable help from Houston. Although about half of the photographic targets had to be scrubbed, Roosa was able to obtain photographs of Descartes with a Hasselblad camera and confirm that it was a suitable landing point. Roosa also used the Hasselblad to take photographs of the impact point of Apollo 13's S-IVB near [[Lansberg (crater)#Satellite craters|Lansburg B crater]].{{sfn|Moseley 2011|pp=159–160}}{{sfn|Mission Report|pp=9-20–9-22}} After the mission, troubleshooting found a tiny piece of aluminum contaminating the shutter control circuit, which caused the shutter to operate continuously.{{sfn|Mission Report|pp=14-42–14-43}}

Roosa was able to see sunlight glinting off ''Antares'' and view its lengthy shadow on the lunar surface on Orbit 17; on Orbit 29 he could see the sun reflecting off the ALSEP.{{sfn|Mission Report|p=9-20}} He also took astronomical photographs, of the [[Gegenschein]], and of the [[Lagrangian point]] of the Sun-Earth system that lies beyond the Earth (L{{sub|2}}), testing the theory that the Gegenschein is generated by reflections off particles at L{{sub|2}}. Performing the [[bistatic radar]] experiment, he also focused ''Kitty Hawk''{{'s}} VHF and S-band transmitters at the Moon so that they would bounce off and be detected on Earth in an effort to learn more about the depth of the lunar regolith.{{sfn|Orloff & Harland 2006|p=401}}{{sfn|Mission Report|pp=4-1–4-3}}
