This "Rocket" model felt-tipped marker was carried by Command Module Pilot Michael Collins on the Apollo 11 mission in July 1969. NASA purchased a number of these pens from the Duro Pen Company for use by astronauts during the Apollo and Skylab program. It is constructed with a chrome body and typical "felt" tip. It also has a small velcro tab attached to keep it secure in the weightless environment.
Donated to the National Air and Space Museum by Michael Collins in 1985.
