Jesco Hans Heinrich Max Freiherr von Puttkamer (22 September 1933 – 27 December 2012) was a German-American aerospace engineer, senior manager at NASA, and a pulp science fiction writer.

In 1962, Puttkamer left Germany for the United States, where he was recruited into Wernher von Braun's rocket team at the NASA Marshall Space Flight Center in Huntsville, Alabama.

Puttkammer was a consultant and technical advisor for Star Trek: The Motion Picture (1979), contributing the hypothetical theory behind the faster-than-light space warp drive, and the wormhole effect featured in the film.

Puttkamer said that among his most treasured achievements at NASA were: his contributions to the Apollo program; the lunar landing in 1969, which fulfilled President John F. Kennedy's mandate; and recovering America's experimental space station Skylab after its disastrous launch into orbit on 14 May 1973.

He often spoke of "rescuing" the backup Skylab from being scrapped, so it could be publicly displayed in the National Air and Space Museum in Washington, D.C.[citation needed] An interview of Puttkamer by Jörg Weigand was published in Perry Rhodan, Issue 2302.

The episode, hosted by Volker Panzer, titled "Moonstruck", was a retrospective on German contributions to space exploration, and focused heavily on the Apollo Moon landing.
