NASA

In 1988 I was living in San Antonio, Texas. My elementary school had a science club, and in hopes of scoring some points during show & tell, my Dad had a friend who worked at NASA mail me a packet of promotional sheets of planned NASA projects, like Space Station Freedom (whose plans were later turned into the International Space Station), a lunar base, and getting man to Mars by 2019 (!). The late '80s were a heady time for planned space exploration; Reagan's Star Wars program and the Cold War put a fire under NASA's seat, but a combination of budget restrictions, accidents (the Challenger tragedy was barely 3 years old), fall of the Berlin Wall and the USSR becoming the Russian Federation put a stop to most of them. I can't remember if anyone was impressed by my paintings (one of which is currently for sale on Allposters). Besides a pair of Mickey Mouse ears from my childhood, I think this are the oldest possessions I still have.

Alan B. Chinchar was an illustrator and ad executive who painted some of the most recognizable NASA space art. His website is still active, though hasn't been updated since 2008.

The booms extending from the solar array are the Canadarm system, used to move items around the outside of the station & payload from a supply vessel (later fitted with a camera to inspect the shuttle for damage). Judging by the back of this promo sheet, it is one of the few planned components of Space Station Freedom that was actually used in the ISS. 

All I can find about Harold Smelcer is that he probably illustrated a children's book called Christopher's Little Airplane.

From what I know about life on the actual ISS, that is way too many people in 1 module, and the entire inside gets covered in bacteria before too long. In short, space stations are like living in a petri dish. 

At least Harold didn't pull a Gravity and had the long hair look like it's in microgravity too. From what I've seen of the actual ISS, there is not enough crap floating around in this artist's rendition. 

This is essentially a hodgepodge of potential living situations in a proposed lunar base. The thermal radiator looks a lot like a giant volleyball net. 

Astronauts performing experiments on Mars while a freaking dust storm approaches. None of these promotional materials make any reference to sending a robot to Mars; y'know, the thing we actually ended up doing. From the back: President Bush set a goal for such a landing for the year 2019.
