INTERNATIONALE AUKTION 168<br />

Italian Airmail History |<br />

lot # 3015<br />

Experimental Shipyard of Vigna<br />

di Valle, 3 October 1908; flight of<br />

the first Italian Military Airship,<br />

designed by Arturo Crocco and<br />

Ottavio Ricaldoni<br />

On this occasion Crocco, now in his eighties, presented his memoir entitled "One year exploratory tour Earth Mars Venus Earth",<br />

which hypothesized the exploitation of the gravitational fields of Mars and Venus to reduce interplanetary travel time. His study<br />

proved important, and was a first contribution to the famous “gravity assist” or “swing-by” manoeuvre, which NASA began to<br />

use on some interplanetary missions in the 1960s. Here, the gravitational force of a planet was exploited through a close transit,<br />

properly calculated, which served to relaunch a space probe to the next destination: it was a boost of energy that allowed the spacecraft<br />

to explore the solar system in more depth.<br />

On 31 October 1908, Crocco made<br />

a round trip from Vigna di Valle to<br />

Rome, covering 80 km in about 1:30<br />

minutes and its airship became the<br />

first aircraft to fly over the capital,<br />

at 500 meters above sea level,<br />

making a great impression.<br />

lot # 3015<br />

The study remained famous, and Americans referred to it as the Crocco<br />

Mission and Crocco's Multi-planet Trajectory. For Crocco, this was his<br />

last, but once again relevant, contribution to the nascent field of space<br />

science.<br />

The name of Gaetano Arturo Crocco, almost unknown in our schools, is<br />

inscribed in the Space Hall of Fame in Alamogordo, New Mexico. Crocco<br />

is one of the very few Italians, together with Enrico Fermi, for whom this<br />

honour has been reserved.<br />
