Sunita williams returns to earth: NASA's Estrinott Sunita Williams and Buch Wilmore have finally returned to the earth after spending 9 months at the International Space Center (ISS) in Space. All 4 Astronauts of NASA returned to Earth from ISS via Spacecraft capsules of SpaceX. SpaceX's Capsule tried a 17 -hour return to the Indian time on Wednesday (March 19) on the banks of Florida at 3.27 am on the banks of Florida.
The visit was accompanied by Sunita Williams and Buch Wilmore along with NASA's Nick Heg and Russian Space Agency Rosscosmos cosmonot Alexander Gorbulnonov. About an hour after SpaceX's capsules were splashed on the earth, Sunita Williams laughed and shook hands towards the camera.
However, there were several hours before the joy of returning to the earth after a long wait of nine months, when the whole world crossed its fingers with all the astronauts. The most difficult phase of SpaceX's dragon spacecraft was during the Earth's entry into the Earth's atmosphere. During this period, the speed of the spacecraft was more than 28,800 kilometers per hour. Due to the friction, the temperature of the exterior of the spacecraft was around 1,600 degrees Celsius. Due to so much temperature, the spacecraft was descending like a fire shell in the Earth's atmosphere. At the same time, due to the heat shield in the spacecraft, all the astronauts sitting in it returned to the safe earth.

SpaceX equipped its dragon capsules with the heat-resident of pica's phenolic-impregnated carbon ablator to protect the earth's atmosphere. This light weight material was first used by NASA. After this, SpaceX started using PICA tiles for cargo and human movement from the international space station.
