Question: When did The Rocket retire?

Context paragraphs:
The Rocket (2005 film): The Rocket (Canadian French: Maurice Richard , also known as The Rocket: The Legend of Rocket Richard and The Rocket: The Maurice Richard Story) is a French-Canadian biopic about the ice hockey player Maurice "The Rocket" Richard.  It stars Roy Dupuis and was directed by Charles Binamé.  It features appearances by National Hockey League players Mike Ricci, Sean Avery, Vincent Lecavalier, Philippe Sauvé, Stéphane Quintal, Ian Laperrière, and Pascal Dupuis.

Falcon 9 booster B1021: Falcon 9 booster B1021 is a first-stage reusable rocket booster for the Falcon 9 orbital launch vehicle manufactured by SpaceX.  B1021 became the first rocket to land vertically on a ship at sea, and is the first orbital-class first-stage core to have been reflown in the history of rocketry.  This Falcon 9 booster was first launched on April 8, 2016 for Falcon 9 flight 23 carrying a Dragon spacecraft on the CRS-8 mission to the International Space Station and landed vertically on an autonomous spaceport drone ship (ASDS).  After recovery, inspections and refurbishing, it was launched again on March 30, 2017 for the SES-10 mission (Falcon 9 flight 32), and recovered successfully a second time.  This event marks a milestone in SpaceX's drive to develop reusable rockets and reduce launch costs.  Following the second flight, SpaceX stated that they plan to retire this booster and donate it to Cape Canaveral for public display.

Able (rocket stage): Able rocket stage was a rocket stage manufactured in the United States by Aerojet for the Vanguard rockets used in the Vanguard project from 1957 to 1959.  The rocket engine stage use as a rocket propellant Nitric acid and UDMH.  Able rocket stage was the second of three stages on the multistage rocket Vanguard.  The Able rocket stage was discontinued in 1960.  A further improved versions were used in the upper stage in the Thor rocket family (Thor-Able).  An upgrade to the Able Stage was the Thor-Ablestar rocket.  The Ablestar second stage was an enlarged version of the Able rocket stage, which gave the Thor-Ablestar a greater payload capacity compared to the Thor-Able.  It also incorporated restart capabilities, allowing a multiple-burn trajectory to be flown, further increasing payload, or allowing the rocket to reach different orbits.  It was the first rocket to be developed with such a capability and development of the stage took a mere eight months.

Glenn R. Brindel: Glenn R. Brindel (born 1943) is a former United States Navy officer.  He was the commanding officer of USS "Stark" and was in command when the ship was attacked and struck by two Exocet missiles in the Persian Gulf on May 17, 1987.  The incident review board, led by Rear Admiral Grant Sharp, recommended he be court-martialed for his actions.  However, he was relieved of command and given non-judicial punishment by Adm. Frank B. Kelso II, commander of the Atlantic fleet.  According to the "New York Times", in 1987 he received a letter of reprimand and elected to retire early.  He had not served as a captain long enough to retire at that grade, so he had to retire at the rank of commander.  The U.S. Naval Register, however, lists Brindel as retiring October 2, 1990, as a captain.  37 sailors were killed in the attack.

Terrier Malemute: The Terrier Malemute is a two-stage American sounding rocket typically used for smaller payloads (less than 180 kg ).  Both the Terrier first stage and the Malemute second stage use solid fuel.  The Terrier burns for approximately 5.2 seconds, and the Malemute burns for approximately 21.5 seconds.  The first stage booster consists of a surplus Navy Terrier MK 12 Mod 1 rocket motor with four 340-square-inch (0.22 m) fin panels arranged in a cruciform configuration.  The Terrier rocket booster has a diameter of 18 inches (460 mm).  The second stage solid rocket is a Thiokol Malemute TU-758 rocket motor, specially designed for high altitude research rocket applications.  Apogee is approximately 400 km (220 nmi) for a 500 lb (230 kg) payload or 700 km (380 nmi) for a 91 lb (41 kg) payload.  For a payload weight of 200 lb (91 kg), the acceleration during the boost phase is 26 "g".

Maurice Richard: Joseph Henri Maurice "Rocket" Richard {'1': ", '2': ", '3': ", '4': "} ( ; ] ; August 4, 1921 – May 27, 2000) was a Canadian professional ice hockey player who played 18 seasons in the National Hockey League (NHL) for the Montreal Canadiens.  He was the first player in NHL history to score 50 goals in one season, accomplishing the feat in 50 games in 1944–45, and the first to reach 500 career goals.  Richard retired in 1960 as the league's all-time leader in goals with 544.  He won the Hart Trophy as the NHL's most valuable player in 1947, played in 13 All-Star Games and was named to 14 post-season NHL All-Star Teams, eight on the First-Team.  On January 1, 2017, in a ceremony prior to the Centennial Classic, Richard was part of the first group of players to be named one of the '100 Greatest NHL Players' in history.

Nuclear thermal rocket: A nuclear thermal rocket is a proposed spacecraft propulsion technology.  In a nuclear thermal rocket a working fluid, usually liquid hydrogen, is heated to a high temperature in a nuclear reactor, and then expands through a rocket nozzle to create thrust.  In this kind of thermal rocket, the nuclear reactor's energy replaces the chemical energy of the propellant's reactive chemicals in a chemical rocket.  The thermal heater / inert propellant paradigm as opposed to the reactive propellants of chemical rockets turns out to produce a superior effective exhaust velocity, and therefore a superior propulsive efficiency, with specific impulses on the order of twice that of chemical engines.  The overall gross lift-off mass of a nuclear rocket is about half that of a chemical rocket, and hence when used as an upper stage it roughly doubles or triples the payload carried to orbit.

Pendulum rocket fallacy: The pendulum rocket fallacy is a common fundamental misunderstanding of the mechanics of rocket flight and how rockets remain on a stable trajectory.  The first liquid-fuel rocket, constructed by Robert Goddard in 1926, differed significantly from modern rockets in that the rocket engine was at the top and the fuel tank at the bottom of the rocket.  It was believed that, in flight, the rocket would "hang" from the engine like a pendulum from a pivot, and the weight of the fuel tank would be all that was needed to keep the rocket flying straight up.  This belief is incorrect.  In actuality, the stability of such a rocket is dependent on other factors.  Basic Newtonian mechanics shows that Goddard's rocket is just as stable (or unstable) as it would be if the engine had been mounted below the fuel tank (as it is in most modern rockets).

Ad Astra Rocket Company: The Ad Astra Rocket Company is an American rocket propulsion company dedicated to the development of advanced plasma rocket propulsion technology.  Located in Webster, Texas, three miles away from NASA's Johnson Space Center, the company was incorporated on January 14, 2005.  The President and CEO of Ad Astra Rocket Company is retired astronaut, Dr. Franklin Chang Díaz.  The company has been working on Chang Díaz's concept of the Variable Specific Impulse Magnetoplasma Rocket, known by its acronym VASIMR.  The VASIMR is intended to achieve several advantages over current chemical rocket designs, including lunar cargo transport, in-space refueling, and ultra-high speeds for distant space missions.

Rocket engine: A rocket engine is a type of jet engine that uses only stored rocket propellant mass for forming its high-speed propulsive jet.  Rocket engines are reaction engines, obtaining thrust in accordance with Newton's third law.  Most rocket engines are internal combustion engines, although non-combusting forms (such as cold gas thrusters) also exist.  Vehicles propelled by rocket engines are commonly called rockets.  Since they need no external material to form their jet, rocket engines can perform in a vacuum and thus can be used to propel spacecraft and ballistic missiles.
