That is amazing news. Because we can’t believe it. Antarctica is a region that is not facing such a condition very easily. You know both regions Antarctic and Arctic are covered with ice glaziers. The coldest temperature was maintained there. Actually human beings can’t live in an area like the above. Now according to the explorations of the NASA scientists, they said that Antarctica faced a danger of melting. We can’t tell if that is good or bad. That is good for other people. Because they can even migrate to those areas to live.
But that is unfortunate for some animals. That means animals that live in cold conditions. Examples for polar bears and penguins. What can happen after the melting down of the whole Antarctica region?
Now we will see their proof and facts put forward for the melting down of Antarctica.
Melting down of Antarctica
The melting of Antarctica was recorded because of the heat waves. Definitely there has to be a reason for some incident. Therefore heat waves are the causing agent for the melting. Antarctica experienced that heatwave earlier in February. From that season there is a high temperature recorded under Antarctica. That means a temperature greater than the normal temperature. The recent proof of satellite shows some important details. That shows how heat waves affected the ice caps and the glaziers.
Do you know the special satellite that made these special images? That is the Landsat 8 satellites. Also, that shows the northern tip of the Antarctic peninsula. That recent closeup was done on the 4th of February this year. It showed there are ice caps in Antarctica the same as before. But later the next closeup was done on the 13th of February. There are blue items in there. Actually that means there are melted ponds. There are no ponds there. So those are surely the melted lands.
Not only us but also scientists are excited about this. They can’t believe even these ice glaciers melted so soon. Eagle Island is the research base of these conditions. Scientists didn’t see this condition as an advantage. They see this as a symbol of a hazardous situation. They worry about the future.
I told the reason for the above warm conditions. That heat waves are not difficult to recognize. They are capable of identifying the change in the temperature pattern when the note down the varying temperature. The heat waves liquefied around 20% of Eagle ‘s island. That is the seasonal snow accumulation.
Those are some main facts related to the melting down of Antarctica. Then we will see the founder of such a big secret. That is the worldwide famous institution NASA. We will see some facts about NASA.
NASA & Antarctica
NASA means the national aeronautics and space administration. This is a worldwide famous company in the space science field. This is owned by the United Nations government. This was started on the 29th of July 1958. The above company has the motto of the for the benefit of all. NASA had performed the projects including the Apollo moon landing mission, Skylab Mission. Mainly NASA is helping the ISS. ISS is the international space station. Plus they are producing the crew vehicle. You know about that. One day humans can go to a universe similar to the journeys we are going on.
Currently, NASA is continuing the research about Mars 2020. That is by the insight rover. Other than Mars NASA is continuing investigations of Saturn and the Jupiter.
Those are the main facts about the worldwide famous space authority. Then after that, we will see about the special instrument that made investigations of the Antarctic secret. That is,
Landsat 8 imagined Antarctica
This is a production of the American earth observation satellite. On the 11th of February 2013, the satellite was launched first. Landsat is the short form of the Landsat data continuity mission. To make this NASA and the USGS cooperated with each other. This is an earth imaging Mission. During that Mission, it imagined the region of Antarctica.
Landsat has an estimated Mission time of about 5- 10 years. There are mainly two payloads in this Landsat. Those are the operational land imager and the Thermal infrared sensor. Those two collect data for the short wave thermal band and the longwave thermal band.
You know there is a ground system. That has certain functions. Those are controlling the satellite and commanding. And the management of the satellite.
So I described all the related details about the Antarctica mission. Sometimes this condition can disappear after some time. That can be because of this dry condition. However, NASA and the Landsat 8 will continue their work in the future too. We can expect more from them. We can know them.
