The Hubble Space Telescope is named after Edwin Hubble, an early 20th century astronomer who discovered galaxies beyond our own Milky Way galaxy. It is an optical Ritchey–Chrétien telescope (an improved Cassegrain reflector). Star light enters the telescope and is collected by a large 7 foot, 10.5 inch (2.400 meter) diameter hyperbolic mirror at the back end. The light is reflected forward to a smaller hyperbolic mirror, which focuses the light and projects it back through an opening in the main reflector. The light is then gathered by the electronic sensors of the space telescope. These mirrors are among the most precise object ever made, having been polished to an accuracy of 10 nanometers.

The Hubble Space Telescope is 43.5 feet (13.259 meters long. The light tube has a diameter of 10 feet (3.048 meters) and the aft equipment section is 14 feet (4.267 meters) in diameter. The spacecraft weighs 27,000 pounds (12,247 kilograms).

The HST orbits the Earth every 97 minutes at an altitude of 320 nautical miles (593 kilometers). The telescope was last serviced in 2009. Originally designed to operate for 15 years, the HST is now in its 26th.

11 April 1981, 12:00:03 UTC, T minus Zero: Space Shuttle Columbia (OV-102) lifted off from Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida, on mission STS-1, the very first orbital flight of the series of reusable space vehicles. Aboard were mission commander John Watts Young and shuttle pilot Robert L. Crippen.

John Young, a former U.S. Navy test pilot and holder of 21 world flight records, was NASA’s most experienced astronaut. He had served as Pilot of Gemini III; backup pilot, Gemini IV; Commander for Gemini 10; Command Module Pilot on Apollo 10; back-up commander for Apollo 13; Commander, Apollo 16; and back-up commander for Apollo 17. Young retired from the Navy in 1976 with the rank of captain.

STS-1 was Bob Crippen’s first space flight.

On 14 April, Columbia landed at Edwards Air Force Base in the high desert of Southern California. It had completed 37 orbits. The total mission duration was 2 days, 6 hours, 20 minutes, 53 seconds.

Columbia was the second of six orbiters built by Rockwell International at Palmdale, California. Construction began 27 March 1975. It was 122.17 feet (37.237 meters) long with a wingspan of 78.06 feet (23.793 meters) and overall height of 56.67 feet (17.273 meters). At rollout, 8 March 1979, OV-102 weighed 159,289 pounds (77,252.3 kilograms), and approximately 178,000 pounds (80,740 kilograms) with its five Rocketdyne RS-25 main engines installed. At launch, the all-up weight of the vehicle was 219,258 pounds (99,453 kilograms).

Columbia was returned to Rockwell for upgrades and modifications from August 1991 to February 1992. It was overhauled and upgraded again at Palmdale in 1994 and 1999.

STS-1 was the first of 135 missions of the Space Shuttle Program. 28 were flown by Columbia (OV-102). During those flights, Columbia spent 300 days, 17 hours, 40 minutes, 22 seconds in space. It completed 4,808 orbits of the Earth and travelled 125,204,911 miles (201,497,772 kilometers).

Columbia was destroyed 1 February 2003 as it disintegrated during reentry. All seven of the astronauts aboard were lost.

11 April 1970: At 2:13:00 p.m., Eastern Standard Time, Apollo 13 was launched from Launch Complex 39A at  the Kennedy Space Center, Cape Canaveral, Florida. This mission was planned to be the third manned lunar landing. The destination was the Fra Mauro Highlands. In command was Captain James A. Lovell, Jr., United States Navy. The Command Module Pilot was John L. “Jack” Swigert, Jr. (who was originally scheduled as the backup CSM pilot, but had replaced Lieutenant Commander T. Kenneth Mattingly II, USN, just three days before launch). and the Lunar Module Pilot was Fred W. Haise, Jr., A NASA astronaut (formerly a U.S. Marine Corps and U.S. Air Force fighter pilot, test pilot and instructor).

The crew change had been made because it was believed that Ken Mattingly had been exposed to measles and NASA administrators did not want to risk that he might become ill during the flight.

At T + 000:05:30.64, while accelerating toward Earth orbit, the center J-2 engine on the Saturn S-II second stage shut down 2 minutes, 12.36 seconds early, which required the other four engines to increase their burn by 34.53 seconds, and the S-IVB third stage engine had to burn 9 seconds seconds longer than planned to achieve the necessary velocity for orbital insertion.

The Apollo 13 mission did not go as planned. An explosion inside the service module was a very near disaster, and the lunar landing had to be aborted. Returning the three astronauts safely to Earth became the primary task.

The Saturn V rocket was a three-stage, liquid-fueled heavy launch vehicle. Fully assembled with the Apollo Command and Service Module, it stood 363 feet (110.642 meters) tall. The first and second stages were 33 feet (10.058 meters) in diameter. Fully loaded and fueled the rocket weighed 6,200,000 pounds (2,948,350 kilograms). It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.

The first stage was designated S-IC. It was designed to lift the entire rocket to an altitude of 220,000 feet (67,056 meters) and accelerate to a speed of more than 5,100 miles per hour (8,280 kilometers per hour). The S-IC stage was built by Boeing at the Michoud Assembly Facility, New Orleans, Louisiana. It was 138 feet (42.062 meters) tall and had an empty weight of 290,000 pounds (131,542 kilograms). Fully fueled with 203,400 gallons (770,000 liters) of RP-1 and 318,065 gallons (1,204,000 liters) of liquid oxygen, the stage weighed 5,100,000 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust, each, for a total of 7,610,000 pounds of thrust at Sea Level. These engines were ignited seven seconds prior to lift off and the outer four burned for 168 seconds. The center engine was shut down after 142 seconds to reduce the rate of acceleration. The F-1 engines were built by the Rocketdyne Division of North American Aviation at Canoga Park, California.

The S-II second stage was built by North American Aviation at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The second stage weighed 80,000 pounds (36,000 kilograms) empty and 1,060,000 pounds loaded. The propellant for the S-II was liquid hydrogen and liquid oxygen. The stage was powered by five Rocketdyne J-2 engines, also built at Canoga Park. Each engine produced 232,250 pounds of thrust, and combined, 1,161,250 pounds of thrust.

The Saturn V third stage was designated S-IVB. It was built by Douglas Aircraft Company at Huntington Beach, California. The S-IVB was 58 feet, 7 inches (17.86 meters) tall with a diameter of 21 feet, 8 inches (6.604 meters). It had a dry weight of 23,000 pounds (10,000 kilograms) and fully fueled weighed 262,000 pounds. The third stage had one J-2 engine and also used liquid hydrogen and liquid oxygen for propellant. The S-IVB wou place the Command and Service Module into Low Earth Orbit, then, when all was ready, the J-2 would be restarted for the Trans Lunar Injection.

Eighteen Saturn V rockets were built. They were the most powerful machines ever built by man.

3 March 1969: At 11:00:00 a.m. Eastern Standard Time (16:00:00 UTC), Apollo 9 Saturn V (AS-504), the second manned Saturn V rocket, is launched from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. Aboard are astronauts Colonel James Alton McDivitt, U.S. Air Force, the Spacecraft Commander; Colonel David Randolph Scott, U.S. Air Force, Command Module Pilot; and Mr. Russell Louis Schweickart (formerly an Air Force pilot), Lunar Module Pilot. McDivitt and Scott were on their second space flight. Rusty Schweickert was on his first.

The 10-day Earth orbital mission is used to test docking-undocking with the lunar module, and to certify the LM as flight-worthy. This was necessary before the program could proceed to the next phase: The Moon.

The Apollo Command/Service Module was built by the Space and Information Systems Division of North American Aviation, Inc., at Downey, California.

The SPS engine was an AJ10-137, built by Aerojet General Corporation of Azusa, California. It burned a hypergolic fuel combination of Aerozine 50 and nitrogen tetraoxide, producing 20,500 pounds of thrust (91.19 kilonewtons). It was designed for a 750 second burn, or 50 restarts during a flight.

The Apollo Lunar Module was built by Grumman Aerospace Corporation to carry two astronauts from lunar orbit to the surface, and return. There was a descent stage and ascent stage. The LM was intended only for operation in the vacuum of space, and was expended after use.

The LM was 23 feet, 1 inches (7.036 meters) high with a maximum landing gear spread of 31 feet (9.449 meters). It weighed 33,500 pounds (15,195 kilograms). The spacecraft was designed to support the crew for 48 hours, though in later missions, this was extended to 75 hours.

The Descent Stage was powered by a single TRW LM Descent Engine. The LMDE used hypergoloc fuel and was throttleable. It produced from 1,050 pounds of thrust (4.67 kilonewtons) to 10,125 pounds (45.04 kilonewtons). The Ascent Stage was powered by a Bell Aerospace Lunar Module Ascent Engine. This also used hypergolic fuels. It produced 3,500 pounds of thrust (15.57 kilonewtons).

This flight was a demonstration of the combined Apollo Command Module and the Service Module. The second production Apollo capsule, CM-009, and the first production service module, SM-009, were launched by the first Saturn IB, SA-201. The Apollo capsule reached a maximum altitude of 305.8 miles (492.1 kilometers) and landed in the Atlantic Ocean 5,267 miles (8,477 kilometers) from Cape Canaveral.

The flight was successful, though several problems occurred  These were identified and corrected on the following production vehicles.

The Saturn IB consisted of an S-IB first stage and an S-IVB second stage. The S-IB was built by Chrysler Corporation Space Division at the New Orleans Michoud Assembly Facility. It was powered by eight Rocketdyne H-1 engines, burning RP-1 and liquid oxygen. Eight Redstone rocket fuel tanks containing the RP-1 fuel surrounded a Jupiter rocket tank containing the liquid oxygen. The S-IB stage is 80 feet, 2 inches (24.435 meters) long, with a diameter of 21 feet, 5 inches (6.528 meters). The empty weight of this stage was 85,000 pounds (38,555 kilograms). Fully fueled, it weighed 498,099 pounds (225,934 kilograms). Total thrust of the S-IB stage was 1,600,000 pounds (7,117,155 Newtons) and it carried sufficient propellant for 2 minutes, 35 seconds burn time. This would lift the vehicle to an altitude of  37 nautical miles (69 kilometers).

The Douglas Aircraft Company-built S-IVB second stage was assembled at Huntington Beach, California. It was powered by one Rocketdyne J-2 engine, also fueled by liquid hydrogen and liquid oxygen. The S-IVB is 60 feet, 1 inch (18.313 meters) long with a diameter of 21 feet, 8 inches (6.604 meters). The second stage had an empty weight of 28,400 pounds (12,882 kilograms) and gross weight was 261,900 pounds (118,796 kilograms). The single engine produced 232,250 pounds of thrust (1,033,100 Newtons) and and its burn time was 7 minutes, 55 seconds.

The AS-201 223 feet, 6 inches (68.123 meters). The total vehicle weight was 1,320,220 pounds (598,842 kilograms). It was capable of launching a 46,000 pound (20,865 kilogram) payload to Earth orbit.

After being recovered, the AS-201 Apollo command module was used for drop tests. It is at the Strategic Air and Space Museum, Ashland, Nebraska.
