Hi,
since it's almost 25 years since the launch of the Giotto mission to Comet Halley, I guess this might as well be a "25th Anniversary Edition" add-on for Celestia 1.6.0 .

Includes a new spacecraft model and trajectory files, modification for comet 1P/Halley during flyby orbit, additional comet 26P/Grigg-Skjellerup.

Trajectory reconstructed using Orbiter Spaceflight Simulator and JPL Horizons data, from launch in 1985 to 2016. Includes flybys of Halley, Grigg-Skjellerup, Earth.
