On this day in 1911, the first around-the-world telegram sent, 66 years before Voyager II launch
On this day in 1911, a dispatcher in the New York Times office sends the first telegram around the world via commercial service. Exactly 66 years later, the National Aeronautics and Space Administration (NASA) sends a different kind of message–a phonograph record containing information about Earth for extraterrestrial beings–shooting into space aboard the unmanned spacecraft Voyager II.
The Times decided to send its 1911 telegram in order to determine how fast a commercial message could be sent around the world by telegraph cable. The message, reading simply “This message sent around the world,” left the dispatch room on the 17th floor of the Times building in New York at 7 p.m. on August 20. After it traveled more than 28,000 miles, being relayed by 16 different operators, through San Francisco, the Philippines, Hong Kong, Saigon, Singapore, Bombay, Malta, Lisbon and the Azores–among other locations–the reply was received by the same operator 16.5 minutes later. It was the fastest time achieved by a commercial cablegram since the opening of the Pacific cable in 1900 by the Commercial Cable Company.
The Voyager 2 spacecraft is an unmanned interplanetary space probe launched on August 20, 1977. Both the Voyager 2 and the Voyager 1 space probes were designed, developed, and built at the Jet Propulsion Laboratory near Pasadena, California. Identical in form and instruments with its sister Voyager program craft Voyager 1, Voyager 2 was launched on a slower, more curved trajectory that
allowed it to be kept in the plane of the Ecliptic (the plane of the Solar System) so that it could be sent on to Uranus and Neptune by means of utilizing gravity assists during its fly-by of Saturn in 1981 and of Uranus in 1986. Because of this chosen trajectory, Voyager 2 could not take a close-up look at the large Saturnian moon Titan as its sister space probe had. However, Voyager 2 did become the first and only spacecraft to make the spaceflight by Uranus and Neptune, and hence completing the Planetary Grand Tour. This is one that is made practical by a seldom-occurring geometric alignment of the outer planets (happening once every 175 years).
The Voyager 2 space probe has made the most productive unmanned space voyage so far, visiting all four of the Outer Planets and their systems of moons and rings, including the first two visits to previously unexplored Uranus and Neptune. Voyager 2 had two sensitive vidicon cameras and an assortment of other scientific instruments to make measurements in the ultraviolet, infrared, and radio wavelengths, as well as ones to measure subatomic particles in outer space, including cosmic rays. All of this was accomplished at a fraction of the amount of money that was later spent on more advanced and specialized space probes Galileo and Cassini-Huygens. Along with the earlier NASA Pioneer 10 and Pioneer 11, sister probe Voyager 1, and the more recent New Horizons, Voyager 2 is an interstellar probe in that all five of these are on one-way trajectories leaving the Solar System.
