NASA recently proclaimed it will put the “first woman and next man” on the moon by 2024. Despite nearly 60 years of human spaceflight, women are still in the territory of “firsts.” The ...
Put another way, the space ship sees the image change from a red-shift (slower aging of the image) to a blue-shift (faster aging of the image) at the midpoint of its trip (at the turnaround, 3 years after departure); the Earth sees the image of the ship change from red-shift to blue shift after 9 years (almost at the end of the period that the ...
If the samples age more quickly in space, scientists will learn more about the process far faster than they would if studying samples on Earth. It is hoped that will lead to new treatments for age ...

The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
British astronaut Tim Peake became the first man to complete a marathon in space on Sunday, running the 26.2 mile distance while strapped to a treadmill.
This is a list of astronauts by year of selection: people selected to train for a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Until recently, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies.
