Soyuz Spacecraft Successfully reach ISS

Russian Soyuz spacecraft carrying  NASA Astronaut Nick Hague and Christina Koch, and Cosmonaut (Russian Crew members are called as a cosmonaut) Alexey Ovchinin successfully docked International Space Station.

Soyuz Spacecraft

Soyuz is a Russian Spacecraft carries people and supplies to and from the space station. Soyuz Spacecraft also function as lifeboats and one Soyuz spacecraft is always docked to the space station, so that in case of emergency the crew can return to earth through the spacecraft.

After the retirement of the space shuttle in 2011, the Soyuz spacecraft has become the sole means of transportation for crew members going to or returning from the orbiting laboratory.

International Space Station

The International Space Station is a habitable artificial satellite in low Earth orbit. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of re-boost manoeuvres and circles the Earth in roughly 92 minutes and completes 15.5 orbits per day

The ISS programme is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, Physics, Astronomy, meteorology, and other fields.

Air Pollution Raises Diabetes Risk

A study in China has shown that Air pollution raises diabetes risk in China. The findings of the study were based on the data collected from over 88,000 people across 15 provinces, estimating their exposure to PM2.5 based on satellite data from 2004 to 2015.

The study was conducted by researchers from Fuwai Hospital in Beijing and Emory University in the US and was published online by journal Environment International.

Findings of the Study

  • Long-term exposure to harmful smog particles increases the risk of diabetes, The study provides evidence for a link between the country’s air pollution and the disease.
  • Increased prosperity has resulted in changing diets and lifestyles, along with an air pollution crisis that the World Health Organization estimates causes over a million premature deaths every year.
  • The risk of diabetes rose by about 16 per cent for an increase of 10 microgrammes per cubic metre in long-term PM2.5 particle exposure.
  • Similar studies in North America, Europe, Hong Kong and Taiwan have shown links between air pollution with diabetes.

Unites Nations study published in 2017 noted that China is facing the largest diabetes problem in the world with around 11 per cent of its population suffering from metabolic illness. It is expected that the sustained improvement of air quality will help decrease the diabetes epidemic in China.
