Hazza Al Mansouri, the first Emirati astronaut, began carrying out the scientific missions on board the International Space Station (ISS), after he arrived safely at the ISS at 2 am and 12 minutes UAE time, Thursday, September 26, 2019, aboard the Russian Soyuz spacecraft. MS 15 ", with the crew that includes Russian astronaut Oleg Scribochka, and US astronaut Jessica Mir.

The Mohammed bin Rashid Space Center, that the program "Mansouri", in its first day was rather short; because of the arrival of the spacecraft to the International Space Station late. He began his day after taking a break by praying, then communicating with the Moscow ground station.He spoke with the ground team and informed them of his daily schedule, as well as with Dr. Hanan Al-Suwaidi, the astronaut doctor, who follows his health during his time in space.

Al-Mansouri also recorded a short film during the first day and recorded his diary for 15 minutes.

The UAE astronaut then began the experiments he carried with him from the UAE schools as part of the "Science in Space" initiative, launched by Mohammed Bin Rashid Space Center, in collaboration with Nano-Rax, with the participation of 16 schools from the UAE. Al Mansouri conducts these experiments aboard the International Space Station in a microgravity environment, and the results are sent to Earth for comparison with the results of parallel experiments conducted on the ground to build a basis for comparison between the two different environments. This is the result of the UAE's first manned mission to space.
Al Mansouri follows three daily experiments to observe the impact of microgravity, including seed germination and growth of some aquatic organisms, in addition to monitoring the rates of oxidation of steel in the absence of gravity.

It is worth mentioning that the astronaut Hazza Al-Mansouri, is conducting several experiments on the International Space Station to study the interaction of biomarkers of the human body in space compared to experiments conducted on the surface of the Earth, and study indicators of bone condition, disorders in motor activity, perception and perception of time in the astronaut, To fluid dynamics in space, the impact of living in space on humans.
