How do we get to Space?

Cygnus CRS OA-9E, also known as Orbital ATK OA-9E and Northrop Grumman OA-9E, was the tenth planned flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its ninth flight to the International Space Station under the Commercial Resupply Services contract with NASA. Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital's industrial partner Thales Alenia Space.

Cygnus CRS OA-4, also known as Orbital ATK CRS-4 and CRS Orb-4, was the fourth successful flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its third flight to the International Space Station under the Commercial Resupply Services contract with NASA. With the Antares rocket undergoing a redesign following its failure during the Orb-3 launch, OA-4 was launched by an Atlas V rocket. Following three launch delays due to inclement weather beginning on 3 December 2015, OA-4 was launched at 21:44 UTC on 6 December 2015. With a liftoff weight of 7,492 kilograms, OA-4 became the heaviest payload ever launched on an Atlas V. The spacecraft rendezvoused with and was berthed to the ISS on 9 December 2015. It was released on 19 February 2016 after 72 days at the station. Deorbit occurred on 20 February at approximately 16:00 UTC.

Cygnus CRS OA-5, also known as Orbital Sciences CRS Flight 5, was the seventh planned flight of the Orbital Sciences' unmanned resupply spacecraft Cygnus and its sixth flight to the International Space Station under the Commercial Resupply Services contract with NASA. Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation System (COTS) program, Orbital designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft; and a Pressurized Cargo Module which is provided by Orbital's industrial partner Thales Alenia Space. The Cygnus spacecraft for this mission is named the S.S. Alan Poindexter in honor to astronaut Alan G. Poindexter, a deceased space shuttle commander. Poindexter was selected in the 1998 NASA Group (G17) and went into orbit aboard Space Shuttle missions STS-122 and STS-131.

Soyuz 6 was a Soyuz spacecraft which launched on 11 October 1969 11:10 UTC. It launched two cosmonauts for a joint mission with Soyuz 7 and 8. The crew was Georgi Shonin and Valeri Kubasov.

Progress M-MIM2 (Russian: Прогресс М-МИМ2) was a modified Progress spacecraft used to deliver the Poisk module to the International Space Station.

Cygnus NG-10, previously known as CRS OA-10E, is the eleventh flight of the Northrop Grumman unmanned resupply spacecraft Cygnus and its tenth flight to the International Space Station under the Commercial Resupply Services contract with NASA. The mission launched on 17 November 2018 at 4:01 AM EST. This particular mission is part of an extension of the initial CRS contract that enables NASA to cover the ISS resupply needs until the Commercial Resupply Services 2 contract enters in effect.

The Albert Einstein ATV, or Automated Transfer Vehicle 004 (ATV-004), was a European unmanned cargo resupply spacecraft, named after the German-born physicist Albert Einstein. It was built to supply the International Space Station (ISS) with propellant, water, air, and dry cargo, and also to reboost the station's altitude with its thrusters. It was the fourth and penultimate ATV to be built, following the Edoardo Amaldi, which was launched in March 2012. Albert Einstein's components were constructed in Turin, Italy, and Bremen, Germany, and underwent final assembly and testing in Bremen in 2012. The spacecraft left Bremen for Kourou on 31 August 2012 to begin launch preparations.

Progress M-28M (Russian: Прогресс М-28М), identified by NASA as Progress 60 or 60P was a Progress spacecraft used by Roskosmos to resupply the International Space Station.

Progress M-25M (Russian: Прогресс М-25М), identified by NASA as Progress 57 or 57P, is a Progress spacecraft used by Roskosmos to resupply the International Space Station.

Vostok 6 was a Vostok spacecraft which launched on 16 June 1963 09:29:52 UTC. It transported one cosmonaut to Low Earth Orbit. The crew was Valentina Tereshkova.

Cygnus CRS OA-7, also known as Orbital ATK CRS-7, is the eighth flight of the Orbital ATK unmanned resupply spacecraft Cygnus and its seventh flight to the International Space Station under the Commercial Resupply Services contract with NASA. Orbital and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station (ISS). Under the Commercial Orbital Transportation Services (COTS) program, then Orbital Sciences designed and built Antares, a medium-class launch vehicle; Cygnus, an advanced maneuvering spacecraft, and a Pressurized Cargo Module which is provided by Orbital's industrial partner Thales Alenia Space. The OA-7 is named the S.S. John Glenn in honor of astronaut and senator John Glenn, the first US astronaut to orbit the Earth on Mercury 6 and the oldest to go to space on STS-95.

HTV-1, also known as the HTV Demonstration Flight or HTV Technical Demonstration Vehicle, was the first Japanese Space Agency (JAXA) H-II Transfer Vehicle, launched in September 2009 to resupply the International Space Station and support the JAXA Kibo laboratory or JEM. It was an unmanned cargo spacecraft carrying a mixture of pressurised and unpressurised cargo to the space station. After a 52-day successful mission, HTV departed the ISS on 31 October 2009 after being released by the station's robotic arm. The spacecraft re-entered the Earth's atmosphere on 2 November and disintegrated on re-entry as planned.

Soyuz 20 (Russian: Союз 20, Union 20) was an unmanned spacecraft launched by the Soviet Union. It was a long-duration test of the Soyuz spacecraft that docked with the Salyut 4 space station. Soyuz 20 performed comprehensive checking of improved on-board systems of the spacecraft under various flight conditions. It also carried a biological payload. Living organisms were exposed to three months in space. It was reentered on 16 February 1976.
