Christina Hammock Koch, född 2 februari 1979, är en amerikansk astronaut och pilot. Hon togs ut till astronautgrupp 21 i juni 2013[1].

10 december 2020 valde Nasa ut henne som en av 18 personer till deras Artemisprogram som är avsett att sända människor till månen och landa där 2025. Koch är utsedd att vara en astronauterna ombord på Artemis 2. Rymdsonden ska skickas till månen i november 2024 och sedan tillbaka till jorden utan att landa på månen[2]. I ett första skede handlar det dock om att vara NASAs representanter, i NASAs samarbete med de olika företagen som utvecklar utrustning för Artemisprogrammet.

Mellan den 14 mars 2019 och 6 februari 2020 deltog hon i Expedition 59 / 60 / 61 på Internationella rymdstationen (ISS)[1]. Hon har tillbringat 328 dagar i rymden och innehar rekordet för längsta vistelse i rymden av en kvinna.[3]

Rymdfärder

Rymdpromenader

Meir och Koch tar på sig rymddräkter inför den första helt kvinnliga rymdpromenaden från rymdstationen

Sex stycken: 29 mars, 6, 11, 18 oktober, 15, 20 januari 2020.

Sin fjärde gjorde hon den 18 oktober 2019 tillsammans med Jessica Meir. Det var den första rymdpromenad från rymdstationen helt med kvinnliga deltagare. Under den 7 timmar och 17 minuter långa aktiviteten hann de bland annat byta en felande laddningsregulator och installera en ny stötta till Columbus-modulen för att stödja en ny extern nyttolastplattform från ESA (European Space Agency).[4][5][6]

ISS Expedition 59 Patch.svg
The Expedition 59 crew insignia
  • The Expedition 59 patch celebrates the International Space Station’s role as a microgravity science laboratory. The crew, made up of scientists, doctors, engineers and pilots, will conduct hundreds of experiments for the benefit of mankind and our fragile environment on planet Earth.
  • The patch shape depicts the cupola windows. Through these windows, astronauts have made many significant observations of Earth’s ecosystems and they have discovered and documented real-time events like volcanic eruptions and earthquakes.
  • The position of the Earth at the top of the patch depicts where the Earth would be seen by an astronaut from the cupola. It represents the explorers’ unique perspective on his or her home. The image at the center of the patch is the station itself, the largest single structure humans have ever put into space, an engineering marvel.
  • The station is overlaid on an atom, the basic building block of all matter. The atom has three electron orbits with the flags of Russia, the United States of America and Canada, representing the home countries of the Expedition 59 crew. Like electrons in an atom, international cooperation is the basic stabilizing force that enables large scale space exploration.
  • To achieve great deeds, humans from all across the globe must work together in peace with a shared vision. The Expedition 59 patch celebrates the massive scientific accomplishments of the space station while highlighting the importance of global teamwork in understanding our planet and continuing with bold exploration in the future.
ISS Expedition 60 Patch.svg
The Expedition 60 crew insignia
  • The Moon landing is one of the most extraordinary feats of humankind, an embodiment of ingenuity and desire for exploration. The patch of Expedition 60 commemorates the 50th anniversary of that landing: a constellation of three stars with the Moon superimposed forms the letter “L,” the Latin symbol for 50. The Moon is depicted as a waxing crescent, as it was on July 20, 1969.
  • The familiar silhouette of the International Space Station is visible, flying across the night sky. Stars, numerous and bright as seen from the space station, form the shape of an eagle in the same pose as on the iconic patch of the Apollo 11 mission. The sunrise represents the fact that we are still in the early stages of humanity’s exploration of space.
  • The hexagonal shape of the patch represents the space station's cupola, with the six points of the hexagon symbolizing the six crewmembers of Expedition 60. The names and nationalities are not present, as on the original Apollo 11 mission patch, to highlight that space missions – then, now, and in the future – are for Earth and all humankind.
ISS Expedition 61 Patch.svg
The mission insignia for the Expedition 61 crew with Commander Luca Parmitano of ESA (European Space Agency), NASA astronauts Drew Morgan, Christina Koch and Jessica Meir and Roscosmos cosmonauts Alexander Skvortsov and Oleg Skripochka.
  • The Expedition 61 patch represents an exciting and dynamic time aboard the International Space Station as it constantly advances towards a limitless future in space. The overall patch view is from an approaching vehicle in pursuit of the space station. The sun is the most prominent, central element in the patch as the source of energy and life for the Earth, the station and our entire solar system. As the present focus of human spaceflight, the space station is centered in the emblem while barely eclipsing the sun with its tiny shadow, reminding of us that human exploration is a small part of our quest to understand the universe.
  • Fifteen of the sun’s rays represent the 15 original partner members of the space station program, while the 16th ray represents an open invitation for continued collaboration with new partners. The four yellow rays form the cardinal directions of a compass, symbolizing the innate human drive to explore. The advancing terminator represents the dawn of a new day on Earth. The name ring appears to float through space and has no single orientation, emphasizing the variety of viewpoints assembled in an international crew unified under one mission. Nine rays extend beyond the name ring to represent the nine human missions that have braved exploration beyond low-Earth orbit, thus encouraging us to drive boundlessly out into our solar system.
