Coincidentally, the first computer to send a message over the ARPANET (precursor of the Internet) was a SDS Sigma 7: "The first successful message on the ARPANET was sent by UCLA student programmer Charley Kline, at 10:30 pm on 29 October 1969, from Boelter Hall 3420.[41] Kline transmitted from the university's SDS Sigma 7 Host computer to the Stanford Research Institute's SDS 940 Host computer." en.wikipedia.org/wiki/ARPANET

That banner is up there to celebrate that the ship in the photo, the aircraft carrier USS Kearsarge (CV-33), was the recovery vessel for two of NASA's Project Mercury 1-man missions. Astronaut Wally Schirra's mission was the MA 8 designation (stands for Mercury-Atlas 8, the 8th Atlas rocket used in both test and manned flights) and his spacecraft "Sigma 7" splashed down in the Pacific Ocean after orbiting the Earth 6 times in early October, 1962. The capsule, with him in it, were hoisted aboard the Kearsarge before he got out. Astronaut Gordon Cooper's mission was MA 9, respectively, and he was picked up by the Kearsarge mid-May the following Spring after completing 22 orbits before splashing down in the Pacific Ocean aboard "Faith 7", which the final mission in the Project Mercury program.
