Planetary geologists analyze rock samples from Earth and other worlds to determine the chemical compositions of planets in the solar system, which gives important clues regarding the origins and evolution of planetary bodies.
These planetary fragments appear to have been blasted from the surfaces of these worlds by the impact of large asteroids that originated in the asteroid belt between Mars and Jupiter.
To planetary scientists, this indicates that the outer disk was cold enough that the ices of carbon dioxide, methane, and ammonia could form.

 Planetary Grand Tour - Wikipedia, the free encyclopedia
Conceived by Gary Flandro of the Jet Propulsion Laboratory, the Grand Tour would have exploited the alignment of Jupiter, Saturn, Uranus, Neptune, and Pluto, an event that would occur in the late 1970s, and not recur for 176 years.
NASA budget cuts eventually doomed the Grand Tour missions, as well as later proposals for a "mini grand tour".
However, some elements of the Grand Tour were added to the Voyager program, which visited all the outer planets except Pluto.

By December 16, 1971, Fletcher had agreed to delete the TOPS version of Grand Tour from its fiscal 1973 budget request and to replace it with a pair of less expensive Mariner spacecraft to be known as Mariner Jupiter-Saturn to be launched in 1977.
On October 15, 1971, although Grand Tour had not yet been authorized, the space agency issued an "Invitation for Participation in Mission Definition for Grand Tour Missions to the Outer Solar System" to specify its scientific objectives, that is, typical payloads and scientific instruments requiring a long lead-time to develop.
Planetary scientists wanted Jupiter-intensive studies and separate missions to the individual outer planets, while NASA (especially JPL) wanted to send numerous spacecraft to the outer planets, but each one taking advantage of the rare Grand Tour launch window.

And a signature is just as unique as a fingerprint, and back in the 1950s, even when JPL was conducting just rocket launches, engineers would often write their names with a grease pencil somewhere on either the skin of the vehicle or inside.
We would have people sign their name and then these names would be etched onto an aluminum plate that was about 4 by 5 inches big, and the plates would be stored somewhere inside the spacecraft.
I would go to The Planetary Society and see them in groups scanning and sorting, and someone would say, 'Hey, look here -- here's a wonderful print' or 'Here's a wonderful this or that.' It was something that added a little interest to the job they were doing.
