Engine bell nozzle extension for a Rocketdyne RS-2101 Liquid Rocket Engine designed for application on the Mars Viking Orbiter, sealed in its original cleaning bag. Includes its protective red rubber caps and original Rocketdyne shipping crate.

NASA sent two Viking spacecraft to Mars in the summer of 1976, and each were comprised of an orbiter, which would photograph the surface, and a lander, which would study the surface and conduct several experiments. The RS-2101 engine was utilized to provide midcourse trajectory corrections while the Viking was en route to Mars and executed the orbital insertion and orbit trim maneuvers of the Orbiter/Lander spacecraft upon arrival at the red planet. The whole spacecraft would orbit the planet for approximately one month, using the images relayed back to mission control to identify a landing site. The landers then separated and soft landed on the Martian surface, touching down in July and September of 1976. Both orbiters and landers eventually failed or were shut down, but not before achieving all of the mission's scientific objectives, including imaging the Martian surface and searching for evidence of life on the planet. This piece will be crated and shipped from California; the buyer is responsible for all associated costs. No sale/export of this item to non-US citizens or entities.
