The American astronaut was the first to identify the DNA sequence in the universe

The Space Flight Management Center (MCC) announced on October 30 that three astronauts returned safely to Earth after completing 40 scientific experiments lasting 115 days on the International Space Station ( ISS).

Here, US scientist Kate Rubins became the first person to identify DNA sequences in the universe .

According to the report, the Rubins scientist, along with two Japanese scientists Takuya Onishi and Russia's Anatoly Ivanishin, landed in the trees-free grassland near Dzhezkazgan city of Kazakhstan.

After being taken out of the storage compartment and sitting on the prairie to adapt to gravity after nearly 4 months in weightless condition, the three astronauts were taken to a nearby medical camp to health check.

The Soyuz TMA-20M spacecraft leaves the launch pad.

In the last mission, the majority of the 40 studies they performed involved verifying the impact of cosmic environmental conditions on living organisms and matter.

The American astronaut Rubins succeeded in identifying the DNA sequences of mouse, virus and microbial samples like the sequencing carried out by Earth scientists at the same time.

The US Agency for Aeronautics and Space (NASA) said the experiment could help identify dangerous bacteria on the space station so that it can diagnose diseases in space accurately.

In addition to the above experiments, the astronauts also have the task of examining the control system of the new generation Soyuz MS spacecraft to bring the crew connected to the ISS international space station.

Currently, two Russian astronauts Andrei Borisenko and Sergey Ryzhykov, and American astronaut Robert Shane Kimbrough are on ISS after setting foot on this space station on October 22 last.

On November 17, Soyuz MS will also be launched into space to take the new crew to the ISS, including Russian astronaut Oleg Novitsky, and two members from the European Space Agency ( ESA) and NASA are Thomas Pesquet and Peggy Whitson.
