Happy Saturday! Here are five notable things that happened this weekend (June 13 and 14) in history, from monkeys in space to Miranda rights. Let's look back....

1949 - The First Monkey in Space

(Note: The Video above depicts Albert VI, the first rocket monkey to actually survive landing at all...though he died just hours later, along with several of his mouse companions.)

On June 14, 1949, a rhesus monkey named Albert II took a ride on a V2 rocket, reaching an altitude of 83 miles above the surface of the earth. This made him the first monkey in space. He died on impact after his spacecraft's parachute failed.

His predecessor, Albert I, did not reach space (only attaining 39 miles of altitude) and died of suffocation. His successor, Albert III, died in an explosion at 35,000 feet. The first monkey in space to survive the trip at all was Albert VI (see video above), though his post-space life was sadly short.

1951 - UNIVAC I Becomes the First Commercially Available Computer in the U.S.

On June 14, 1951, the United States Census Bureau dedicated UNIVAC I, though it had bought the system a few months earlier. The computer was used for various massive computing tasks, most famously predicting the 1952 presidential election. Using only a 1% sample of the voting populace, UNIVAC I predicted that Dwight Eisenhower would win in a landslide, despite common wisdom that Adlai Stevenson would take the election. The prediction was held back on election night because it seemed so improbable. Oops.

1959 - Disneyland's Monorail Opens

On June 14, 1959, Disneyland opened the first monorail in the United States. ViceĀ President Nixon and his family were present with Walt Disney at the opening (see above; Nixon starts around 2:55). The Nixon kids cut the ribbon, with a little help from Walt. Part of Tomorrowland, the Disneyland Monorail System is still in operation today.

1966 - Miranda v. Arizona Decided

On June 13, 1966, the United States Supreme Court ruled that police must inform suspects of their rights before questioning said suspects. The case had been brought by Ernesto Miranda, who had not been informed that he had the right to a lawyer (or any other rights), and had confessed to police. The practice of reading a suspect his or her rights has since been called "Mirandizing" them. Here are the specific facts that must be provided to a suspect as a result of the historic ruling (plus a confirmation that the suspect understands these rights):

1. You have the right to remain silent.

2. Anything you say can and will be used against you in a court of law.

3. You have the right to an attorney.

4. If you cannot afford an attorney, one will be appointed for you.

1983 - Pioneer 10 Leaves the Central Solar System

On June 13, 1983, Pioneer 10 became the first man-made object to leave the major planets of the solar system. It crossed the orbit of Neptune and just kept going.

The mission officially ended on March 31, 1997, though Pioneer 10 was still transmitting data (the last weak signal received from the probe was received in 2003, when it was 80 AU from earth). The craft was launched in 1972, and carries the famous Pioneer plaque, predecessor to the Voyager Golden Recordā€”both were intended to communicate some information about the human species in case extraterrestrial intelligence ever retrieved the probes.
