If you ever watched Dr. Who in its last two years of production (1988-1989) and looked closely on Ace's jacket, one of her patches is the Enterprise Approach and Landing Test Patch

and another was the mission patch for STS-51L (Challenger's last flight).

Star Trek also honored Challenger at least once, one of the Enterprise-D's shuttlecraft during the run of the Next Generation series (1987-1994) was named the Onizuka, for one of the lost crew members (and of course Star Trek IV was dedicated to the entire crew).

Also, the fortieth anniversary of Doctor Who is coming up this November, the day AFTER the 40th anniversary of the assassination of JFK.
