J. R. Hind discovered asteroid #12 Victoria.

12 Victoria is a large Main belt asteroid, probably composed of silicate rock and nickel-iron, discovered by John Russell Hind on 13 September 1850. Radar and speckle interferometry observations show that the shape of Victoria is elongated, and it is suspected to be a binary asteroid. Victoria has only been observed to occult stars 3 times.

Victoria is officially named after the Roman goddess of victory, but the name also honors Queen Victoria of the United Kingdom. The goddess Victoria (Nike for the Greeks) was the daughter of Styx by the Titan Pallas in Roman mythology. The coincidence with the then-reigning British queen's name caused quite a controversy at the time of discovery, and B. A. Gould, editor of the prestigious Astronomical Journal, adopted the alternate name Clio (now used by 84 Klio) proposed by the discoverer. However, W. C. Bond, of the Harvard College Observatory, then the highest authority on astronomy in America, held that the mythological condition was fulfilled and the name Victoria was therefore acceptable, and his opinion eventually prevailed.

NASA launched Mercury-Atlas 4 (MA-4), the first orbital flight in the Mercury program, as a successful unmanned test of all systems, network, and recovery forces.

Mercury-Atlas 4 (MA-4) was launched 13 September 1961 from Cape Canaveral, Florida, with special vibration and noise instrumentation and a mechanical crewman simulator aboard, in addition to the normal spacecraft equipment. It was an orbital test of the Mercury Tracking Network, and the first successful orbital flight test of the Mercury program. (All previous successful launches were suborbital.) The payload consisted of a pilot simulator (to test the environmental controls), two voice tapes (to check the tracking network), a life support system, three cameras, and instrumentation to monitor levels of noise, vibration and radiation.

The orbital apogee was 123 nautical miles and the perigee was 86 nautical miles. After one orbit, the spacecraft's orbital timing device triggered the retrograde rockets, and the spacecraft splashed in the Atlantic Ocean 161 miles east of Bermuda. A circuit anomaly in the control system caused the landing to occur 120 km uprange from its intended target. Recovery was made 82 minutes after splash-down by the destroyer USS Decatur.

During the flight, only three slight deviations were noted - a small leak in the oxygen system; loss of voice contact over Australia; and the failure of an inverter in the environmental control system. Overall, the flight was highly successful: the Atlas booster performed well and demonstrated that it was ready for the manned flight, the spacecraft systems operated well, and the Mercury global tracking network and telemetry operated in an excellent manner and was ready to support manned orbital flight. The flight demonstrated the ability of the Atlas rocket to lift the Mercury capsule into orbit, of the capsule and its systems to operate completely autonomously, and succeeded in obtaining pictures of the Earth.

The US performed the first successful ASAT interception, destroying a target satellite with an air-launched intercept rocket.

The first successful test interception and destruction of a satellite in space was performed on 13 September 1985.

The air-launched ASAT (Anti-Satellite missile) used in the test was designed and developed by Vought in response to a 1977 Air Force requirement for a small air-launched missile capable of intercepting and destroying enemy satellites in low Earth orbit. The missile consisted of a modified Short Range Attack Missile (SRAM) first stage, a Thiokol Altair III second stage, and a Vought miniature homing vehicle (MHV).

The test ASAT was launched from an F-15 fighter in a steep climb at 38,100 ft (11.613 km) altitude. The "jet powered booster stage" gave the ASAT sufficient initial velocity to reach its target's orbit using its onboard rocket engines. After the first stage separated, the second stage propelled the MHV into space on a collision course with the target, Solwind, orbiting at 326 mi (525 km) altitude. The MHV destroyed the target by ramming it at high speed.

Solwind, the gamma ray spectroscopy satellite launched in 1979, had become functionally useless. Its orbit was decaying rapidly, and it was already scheduled for termination. Solwind's mission was extended several weeks solely to support the test so that it would be "operational" when it was destroyed. Its destruction resulted in 285 cataloged pieces of orbital debris. The last piece of debris remained in orbit until at least May 2004, but had deorbited by 2008.
