These are the 13 LEGO Space sets from 1997 (4 RoboForce + 9 UFO). Up next: 1998 and the final Space subtheme that I will cover.

Interstellar Starfighter geometry
The front section of Interstellar Starfighter has an almost cardioid shape: 28 studs wide by 24 studs deep with a corner radius of 14 studs in the front but 10 in the rear. So half circle / half rounded rect.
Interstellar Starfighter Lights
Interstellar Starfighter’s fiber optics system in action
Fiber Optics System
The fiber optics system had 8 lights and used a (very noisy) micro motor to cycle through the lights (only one would illuminate at a time). It was driven by the same 9V battery box that had been used in Space sets since 1986 (but this was its final appearance).
6979: Interstellar Starfighter
6979-1: Interstellar Starfighter, 1997. Large UFO spaceship has sort of a Star Trek vibe to it. The half saucer in the rear detaches via magnets to form its own small fighter. The only Space set to feature a fiber optic lighting system. Comes with two alien pilots and a droid.
Alien Avenger geometry
Alien Avenger is not a perfect circle but rather a 32 x 32 stud rounded rectangle with a corner radius of 14 studs. (I was proud that my son noticed this!) 🤓
6975: Alien Avenger
6975-1: Alien Avenger, 1997. Large flying saucer comes with detachable mini saucer, small and medium-sized rovers, magnetic crane arm, dual forward blasters, three aliens, and a droid. The mini saucer docks via magnets. Easily my favorite UFO set.
6915: Warp Wing Fighter
6915-1: Warp Wing Fighter, 1997. Looks like a mashup of a flying saucer and an X-Wing. Comes with an alien pilot and a droid. Lots of big printed parts.
6900: Cyber Saucer
6900-1: Cyber Saucer, 1997. Flying saucer piloted by a single blue alien. The saucer spins and can separate from the landing gear. Check out those bright colors and big printed parts!
6836: V-Wing Fighter
6836-1: V-Wing Fighter, 1997. Small spaceship with ample firepower and thrusters piloted by a red droid. Not a bad looking ship.
