Now a class of tiny, boxy spacecraft, known as CubeSats, have just taken their own version of a "pale blue dot" image, capturing Earth and its moon in one shot, NASA said on Tuesday.
One of the CubeSats, called MarCO-B used a fisheye camera to snap its first photo on May 9.
That photo is part of the process used by the engineering team to confirm the spacecraft's high-gain antenna has properly unfolded.
As a bonus, it captured Earth and its moon as tiny specks floating in space, the US space agency added.
"CubeSats have never gone this far into space before, so it's a big milestone. Both our CubeSats are healthy and functioning properly. We're looking forward to seeing them travel even farther," Klesh added.
The cameras of Voyager 1 on February 14, 1990, pointed back toward the Sun and took a series of pictures of the Sun and the planets, making the first ever "portrait" of our solar system as seen from the outside.
Taking these images was not part of the original plan, but the late Carl Sagan, a member of the Voyager imaging team at the time, had the idea of pointing the spacecraft back toward its home for a last look. The title of his 1994 book, "Pale Blue Dot," refers to the image of Earth in this series.
This "family portrait" captures Neptune, Uranus, Saturn, Jupiter, Earth and Venus from Voyager 1's unique vantage point. A few key members did not make it in -- Mars had little sunlight, Mercury was too close to the Sun, and dwarf planet Pluto turned out too dim.
Most never go beyond Earth orbit; they generally stay below 800 kilometres above the planet.
Though they were originally developed to teach university students about satellites, CubeSats are now a major commercial technology, providing data on everything from shipping routes to environmental changes.
InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, will attempt to land on Mars on November 26, NASA said.
