Corona Virus: NASA reports Pollution Levels in China have dropped greatly

On March 2, 2020, NASA (National Aeronautics and Space Administration) reported that Nitrous Oxide pollution in China has declined greatly between January and February 2020.  According to the report, nitrous oxide pollution has declined by more than 100 tonnes of carbon-dioxide.

Highlights

The report says that every year, after New Year Celebrations, air pollution in china peaks to its highest. However, this year, due to economic slowdown caused by the fear of virus, the pollution was at its minimal. This was mainly because of closure of several businesses and factories all over China.

Current Scenario

The World Health Organization has said that COVID-19 can be contained. This is because out of 80 countries that have been infected with the virus, 38 of them have less than 10 cases.

Controversy

Though WHO is optimistic, the Health Agencies believe that the countries have to assess their preparedness in fighting the disease. They say that 30% of those hospitalized with COVID-19 infections require critical care. In such scenario, apart from financial support, the countries should also possess skilled hands that are capable of operating the critical care equipment.

NASA sends probes to map poles of the sun

NASA (National Aeronautics and Space Administration) of the United States and the ESA (European Space Agency) will send space probes to the sun to map its poles. The solar orbiter was launched on February 9, 2020.

Highlights

The probe will use gravitational influence of the Earth and Venus to position itself at 26 million miles from the sun. It is 95% of distance between the sun and the earth. The probe will map the poles for the first time. This will help scientists to observe the solar winds. The solar winds permeate the solar system.

Solar Winds

The solar winds are released from the upper atmosphere of the sun. These winds carry charged particles and magnetic clouds from the sun. These winds are capable of damaging life on the earth. Therefore, it is important to learn about these winds. They are now being filtered by the thick atmosphere around the earth.

The winds are a reason for the planets including the earth to revolve around the sun.
