NASA Announces New Mission in Costa RicaNASA scientists said Thursday they have launched a new study on climate change using a special aircraft that will enter the high troposphere - the lowest level of the earth's atmosphere - in the tropics.
Paul Newman, one of the NASA project's coordinators, said the researchers will look at atmospheric contamination and how the ozone layer is changing.
The US $8 million project involves 140 scientists from the United States and 30 from Costa Rica, Newman told a news conference in San José. The study, conducted from a NASA office at the Juan Santamaría International (San José) airport, started Jan. 14 and will end Feb. 12.
During that time, the WB-57F plane will make 12 trips into the high tropical troposphere, which has barely been studied and is believed to have suffered the largest impact from climate change, officials said.
The plane can fly at an altitude of 60,000 feet and has 29 instruments to measure atmospheric conditions.
NASA scientist Eric Jensen said the agency is also interested in investigating the properties of clouds at high altitude, which are thin and have temperatures as low as 194 Fahrenheit below zero.
Could the NASA announcement yesterday be the answer to the UFO sighting last Friday (Jan. 13), an event that captured the attention of all as they looked up in the afternoon sky and still a source of belief by many.
