Ride was soon back in the rotation, training for her third flight, STS-61-I. This mission was scheduled to be flown no later than July 15, 1986, and was to deploy the Intelsat VI -1 and INSAT 1-C communications satellites and carry the Materials Science Lab-4. The crew was subsequently switched to STS-61-M, a Tracking and Data Relay Satellite System (TRDS) deployment mission scheduled to be flown in July 1986. She also served on two more missions as CapCom. On January 7, 1986, Ride provided a glowing reference for her friend (and eventual biographer) Lynn Sherr for NASA's Journalist in Space Project. Sherr became one of the finalists. During 1985, Ride began an affair with Tam O'Shaughnessy. The two knew each other from the junior tennis circuit, and from when Ride was at Stanford. O'Shaughnessy was now living in Atlanta, and had recently broken up with her female partner. Ride visited when she went to Atlanta on speaking engagements. Hawley was aware that his marriage was in trouble, but not that O'Shaughnessy was more than a friend. Ride still performed her astronaut spouse duties for Hawley when he flew in space for the second time on STS-61-C in January 1986. Astronauts and their spouses were quarantined for a few days before launch, and they stayed at the astronaut beach house at the KSC. Spouses were expected to attend events before and after launches, including the post-mission publicity tour. This could be agonizing for a couple whose marriage was breaking up.
