NASA reported that one American astronaut and two Russian cosmonauts docked at the ISS today. They will remain on board for a period of approximately half a year.
The grandfather and astronaut Jeff Williams will be the first American to spend three stints on board the ISS. He reached the ISS along with his fellow Russian cosmonauts Alexey Ovchinin and Oleg Skripochka.

The latter two were from Roscosmos. The research these three will carry out on the ISS will go on to pave the way for the Mars Mission.
The three embarked on board a Soyuz spacecraft as it headed out for the ISS. The venue of takeoff was Kazakhstan. With their addition to the pre-existing ISS crew, the total number on board reached six.
Tim Kopra, Tim Peake and Yuri Malenchenko comprised the other three. The 250 experiments that will be carried out on board the ISS will be in such subjects as: biology, earth science, physical science and technological development.
Among the list of investigations that are to take place are: fire scenarios in a spacecraft, behavior of soil in microgravity, the effects of a gecko-inspired gripping device and the workings of a 3D printer.
An expandable habitat will also be among the things which will get tested by the three who have docked at the ISS. The inhospitable environment of space requires a habitat.
The Bigelow Expandable Activity Module will be attached to the ISS. It will be tested for a minimum of two years. The purpose of expandable habitats is to prepare NASA and Roscosmos crew members for future trips.
These may be to asteroids or even to Mars. The crew will receive three tons worth of food supplies, fuel, various paraphernalia and research materials.
Throughout the half year stay on board the ISS, grandpa Williams will become an American record-breaker for number of days in space. He will have accumulated a total of 534 days by the end of his sojourn in space.
Thus he will have outdone astronaut Scott Kelly who recently arrived back home on planet earth. It’s been a decade and a half since astronauts have been living on board the ISS.
The advancement of humanity’s most potent knowledge depends on their efforts. What is impossible to carry out on earth becomes an achievable deal in the zero gravity of space. More than 200 people from 15 countries have visited the ISS up until now.
