Fast reconnaissance missions to the outer solar system utilizing energy derived from the gravitational field of Jupiter

evidence

The late-1970s alignment of Jupiter, Saturn, Uranus and Neptune permits a single spacecraft to reach all four by successive gravity assists, an opportunity recurring only on a timescale of roughly 175 to 176 years. V55 verification basis: NOT CHECKED IN THIS RUN. The title, journal, volume and year are given from standard citation practice and the search budget was exhausted before they could be confirmed; the 175 versus 176 year figure differs between accounts and is deliberately given as a range. A curator must verify this citation before publication.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
