At 12:20 UTC, 15 July 1975, Soyuz 19 launched from Gagarin’s Start at Baikonur Cosmosdrome, Kazakh SSR with Alexei Leonov and Valeri Kubasov, both on their second space flights. The launch vehicle was a Soyuz-U three-stage rocket.

At 19:50 UTC, 15 July 1975, Apollo ASTP lifted off from Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida. The crew was Thomas P. Stafford on his fourth space flight, Vance D. Brand on his first, and Donald K. “Deke” Slayton also on his first. The launch vehicle was a Saturn IB.

At 16:19:09 UTC, 17 July 1975, the two orbiting spacecraft rendezvoused in orbit and docked. Using a Docking Module airlock, the two crews each opened their spacecraft hatches and shook hands. The two ships remained joined for 44 hours, separating once for the Soyuz crew to take its turn to maneuver for docking with the Apollo Command and Service Module.

The Apollo command module from the mission is on display at the California Science Center in Los Angeles. The descent module of Soyuz 19 is on display at the RKK Energiya museum in Korolyov, Moscow Oblast, Russia.

This was the last flight of the Apollo spacecraft.

Prior to her acceptance in the cosmonaut corps, Tereshkova had been a textile worker. She was also an amateur parachutist. The qualifications for the Soviet space program were that the women be parachutists under the age of 30 years, less than 170 centimeters (5 feet, 7 inches) tall and weigh less than 70 kilograms (154.3 pounds). After an extensive training program with included pilot training in the Mikoyan Gurevich MiG 15UTI fighter and 120 parachute jumps, Tereshkova and three other women were commissioned as Junior Lieutenants in the Soviet Air Force.

Vostok 5 with Cosmonaut Valery Fyodorovich Bykovsky had been launched two days earlier on the same orbital path. During their flights they came within approximately 5 kilometers (3.1 miles) of each other.

Valentina Tereshkova completed 48 orbits of the Earth, reaching a maximum altitude of 212 kilometers (131.7 miles). Vostok 6 re-entered the atmosphere and Tereshkova parachuted from the capsule near the Pavinskiy Collective Farms, Altai Krai (approximately 150 miles/240 kilometers southwest of Novosibirsk), landing at 08:20 UTC, 19 June 1963. The total duration of her flight was 2 days, 22 hours, 50  minutes.

The Vostok 3KA spacecraft consisted of a spherical crew module and a service module. It could support one person in a full-pressure suit for a maximum of 10 days. There were two view ports. The Vostok used pressurized gas jets for attitude control while in orbit, but was not capable of changing its orbit. The vehicle had a total height of 4.40 meters (14 feet, 5¼ inches) and total mass of 4,730 kilograms (10,428 pounds). The descent module diameter was 2.3 meters (7 feet, 6½ inches) and had a mass of 2,460 kilograms (5,423 pounds).

On descent, the cosmonaut used an ejection seat to leave the capsule prior to Earth landing, and parachuted to the ground.

The Korolev Design Bureau Vostok 8K72K launch vehicle was a three-stage liquid-fueled rocket developed from the Soviet R-7 “Semyorka” intercontinental ballistic missile, using RP-1, a highly refined form of kerosene, and liquid oxygen as propellant. It was 38.36 meters (125 feet, 10 inches) tall and had a maximum diameter of 10.3 meters (33 feet, 9 inches). Total mass at liftoff was 287,375 kilograms (633,553 pounds).

The first stage consisted of four boosters surrounding a central core. Each was powered by one Glushko Design Bureau RD-108 (8D75) engine with four combustion chambers and exhaust nozzles. The RD-108 was rated at 713.600 kilonewtons of thrust (160,424 pounds-force) at Sea Level. Burn time was 118 seconds. The second stage used one RD-108 engine fired for 301 seconds. The third stage had one Kosberg Design Bureau RD-0109 engine rated at 54.520 kilonewtons (12,257 pounds-force) of thrust, with a burn time of 365 seconds.

12 April 1961: At 0607 UTC, Vostok-1 with Cosmonaut Yuri Alexseyevich Gagarin was launched into Earth orbit from the Kosmodrom Baykonur, Kazakhistan. The spacecraft was a spherical Vostok 3KA-3 capsule carried aloft by a Vostok-K rocket.

Gagarin made one orbit of the Earth, with an apogee of 315 kilometers and perigee of 169.kilometers. The orbital period was 89.34 minutes. The orbit was inclined 64.95° with reference to Earth’s axis.

While still in Earth orbit, Senior Lieutenant Gagarin received a field promotion to the rank of major.

His reentry began over Africa. As the spacecraft was descending through 7,000 meters (20,966 feet), he ejected from the capsule and parachuted to the ground, landing near Engels, Saratov Oblast, at 0805 UTC.

Yuri Gagarin was the first human to travel in space.

Vostok I with Yuri Gagarin was launched from Baikonur Cosmodrome, 12 April 1961.

Yuriy Alekseyevich Gagarin (Юрий Алексеевич Гагарин) was born at Klushino, a village in Smolensk Oblast, Russian Soviet Federative Socialist Republic, 9 March 1934. He was the third of four children of Alexey Ivanovich Gagarin and Anna Timofeyevna Gagarina. The family, workers on a collective farm, were displaced by the German invasion of 1941.

Gagarin was drafted by the Soviet Army in 1955 and was sent to flight school. Gagarin received a commission as a lieutenant in the Soviet Air Force in 1957 and was promoted to senior lieutenant two years later.

Lieutenant Gagarin was one of nineteen pilots selected for the space program in 1960. This was further reduced to six cosmonaut candidates. Gagarin and Gherman Titov were the final Two candidates for the first manned space launch, with Gagarin being chosen.

19 February 1986

Mir DOS-7/Proton 8K82K launch at Baikonur Cosmodrome, Site 200, 21:28:23 UTC, 19 February 1986.
Mir DOS-7/Proton 8K82K launch at Baikonur Cosmodrome, Site 200, 21:28:23 UTC, 19 February 1986.

19 February 1986: The core module of the Mir space station (DOS-7) (Dolgovremennaya Orbitalnaya Stanziya) was launched from Site 200 of the Baikonur Cosmodrome aboard a Proton 8K82K rocket. This was the first section of the space station. It consisted of living quarters and environmental systems, engines, and four air locks to which additional modules would be attached.

The Mir was unmanned when it was placed in low Earth orbit. The first two-man crew arrived 15 March 1986 and began bringing the space station systems online. The first expedition stayed aboard for 51 days.

The Mir Core Module was 13.13 meters (43.077 feet) long with a diameter of 4.15 meters (13.616 feet). The solar arrays had a span of 20.73 meters (68.012 feet). The habitable volume of the module was 90 cubic meters (3,178 cubic feet). At launch  it had a mass of 20,400 kilograms (44,974.3 pounds).

The Proton 8K82K was a four-stage liquid-fueled heavy lift rocket. The first stage, Proton K-1, was 21.20 meters (69.554 feet) long with a diameter of 4.15 meters (13.616 feet). Fully fueled, it had a mass of 450,510 kilograms (993,205 pounds). It carried enough hypergolic fuel to power the six RD-253 engines for 124 seconds, producing 67,821.2 kiloNewtons (15,246,812 pounds) of thrust. The second stage, Proton K-2, was 14.00 meters (45.932 feet) long, with the same diameter as the first stage. Its fully-fueled mass was 167,828 kilograms (369,997 pounds). Its four RD-0210 engines burned for 206 seconds, producing 9,596.8 kiloNewtons (2,157,447 pounds) of thrust. The Proton K-3 stage was 6.50 meters (21.326 feet) long, and again, had a diameter of 4.15 meters. The gross mass of the third stage was 50,747 kilograms (111,878 pounds). The single RD-0212 engine burned for 238 seconds, producing 630.2 kiloNewtons (141,675 pounds) of thrust. The final, fourth stage, Proton 11S824, was 5.50 meters (18.045 feet) long with a diameter of 3.70 meters (12.139 feet). Gross mass was 13,360 kilograms (29,454 pounds). It had a single RD-58M engine which burned liquid oxygen and kerosene. It produced 85.02 kiloNewtons (19,113 pounds) of thrust for 610 seconds.

The Proton 8K82K could place a 20,000 kilogram (44,092 pound) payload into low Earth orbit. The rocket was first launched in 1965 and was used until 2003. More than 300 of them were launched.

The Mir space station was continually expanded. It was occupied for 4,592 consecutive days. It remained in orbit until 23 March 2001.

4 January 1959: At approximately 16:40 UTC, the Soviet automatic space probe First Cosmic Ship came within 5,995 kilometers (3,725 miles) of the Moon. It was the first man-made craft to arrive in the vicinity of Earth’s natural satellite.

First Cosmic Ship (which was later known as Мечта (Mechta, “Dream”) and today is called Luna 1) was launched from the Scientific-Research Test Range No. 5 at Tyuratam, Kazakhstan (later named the Baikonur Cosmodrome) at 16:41:21 UTC, 2 January 1959, aboard an 8K72 three-stage launch vehicle.

Mechta was the fourth in a series of lunar probes, and was intended to impact the surface of the Moon.  It was spherical with several antennas, and weighed 361 kilograms (795.9 pounds). The probe carried a magnetometer, Geiger counter, scintillation detector and micrometeorite detector. It was powered by batteries. Radio telemetry equipment relayed the data to Earth.

It was intended that the spacecraft would impact the lunar surface, but an error in programming the third stage burn time caused a near miss. After 34 hours of flight, the probe passed within 5,995 kilometers (3,725 miles) of the lunar surface.  It then entered a solar (heliocentric) orbit between Earth and Mars, where it remains today, circling the Sun every 450.0 days.

The Vostok-L 8K72 was a modified R-7 Semyorka intercontinental ballistic missile. The R-7 rocket was designed by Sergei Pavlovich Korolev, known as The Chief Designer.

The 8K72 version consisted of two core stages with four external boosters. The first stage and each of the boosters were powered by a four-nozzle RD-107 rocket engine burning kerosene and liquid oxygen. Total thrust was approximately 1,100,775 pounds. The second stage used a RD-0105 engine, producing 11,015 pounds of thrust. The Luna 1 was propelled by a third stage which remained attached during the translunar coast phase of flight.

The first two stages were 30.84 meters (101.18 feet) high and weighed 277,000 kilograms (610,680 pounds). The Luna 1 third stage weighed 1,472 kilograms (3,245 pounds), empty. It was 5.2 meters (17.06 feet) long with a diameter of 2.4 meters (7.87 feet).

The 8K72 rocket was capable of launching a 4,000 kilogram (8,818.5 pound) payload into Low Earth Orbit. The last launch of an 8K72 was in 1960, but the current Soyuz launchers are based on this early rocket.

Luna 1 was the first space vehicle to reach escape velocity and leave Earth’s gravitational field; the first to reach the vicinity of the Moon, and the first man-made device to orbit the Sun.

Luna 1 was launched from Tyuratam at 16:41:21 UTC, 2 January 1959.
