The last track on the album was originally scheduled to include a saxophone part recorded by astronaut Ron McNair on the Space Shuttle Challenger, making it the first piece of music to be recorded in space, but on 28 January 1986, 73 seconds after lift-off, the shuttle disintegrated and the entire Challenger crew were killed. The track was dedicated to McNair and the other astronauts on board Challenger. On the album the saxophone part is played by saxophonist Pierre Gossez.
The album reached #9 in the UK charts and #52 in the U.S. charts.
In April 1986, Jarre performed the large-scale outdoor concert Rendez-vous Houston in Houston, Texas, celebrating the 150th anniversary of the founding of Texas. The show attracted a then-world-record live audience of 1.3 million people. The concert was originally to have included a video projection of Ron McNair's performance, recorded in space.
