Buzz Aldrin is an American engineer, former astronaut, and Command Pilot in the United States Air Force. As Lunar Module Pilot on the Apollo 11 mission, he and mission commander Neil Armstrong were the first two humans to land on the Moon. Aldrin set foot on the Moon at 03:15:16 on July 21, 1969 , 9 minutes after Armstrong first touched the surface. One of his first missions was on Gemini 12 where he successfully proved that extravehicular activity could be performed by astronauts, spending over 5 hours outside the craft, thus achieving the goals of the Gemini program and paving the way for the Apollo program.

Robert Zubrin is an American aerospace engineer and author, best known for his advocacy of the manned exploration of Mars. He and his colleague at Martin Marietta, David Baker, were the driving force behind Mars Direct, a proposal intended to produce significant reductions in the cost and complexity of such a mission. The key idea was to use the Martian atmosphere to produce oxygen, water, and rocket propellant for the surface stay and return journey. A modified version of the plan was subsequently adopted by NASA as their "design reference mission". He questions the delay and cost-to-benefit ratio of first establishing a base or outpost on an asteroid or another Project Apollo-like return to the Moon, as neither would be able to provide all of its own oxygen, water, or energy; these resources are producible on Mars, and he expects people would be there thereafter.
Linus Benedict Torvalds is a Finnish-American software engineer who is the creator, and for a long time, principal developer of the Linux kernel, which became the kernel for operating systems such as the Linux operating systems, Android, and Chrome OS. He also created the distributed revision control system Git and the diving logging and planning software Subsurface. He was honored, along with Shinya Yamanaka, with the 2012 Millennium Technology Prize by the Technology Academy Finland "in recognition of his creation of a new open source operating system for computers leading to the widely used Linux kernel". He is also the recipient of the 2014 IEEE Computer Society Computer Pioneer Award and the 2018 IEEE Masaru Ibuka Consumer Electronics Award.
