The U.S.-European satellite, designed to expand decades-old measurements of Wandenberg Air Base – a global sea level, was launched from California into global orbit on Saturday.
The satellite-carrying SpaceX Falcon 9 rocket exploded from Wandenberg Air Base at 9:17 a.m. and headed south toward the Pacific Ocean. The first phase of the eagle returned to the launch site and landed for reuse.
The Sentinel-6 Michael Freelich satellite was launched from the second phase about an hour later. The solar panel was then fitted and first contacted with the controller.
Named after a former NASA official who played a key role in space-based ocean development, the satellite’s main weapon is a very accurate radar altitude that bounces energy from the sea surface as it covers the world’s oceans. The same twin Sentinel-6B will be launched in 2025 to ensure the record continues.
Since the launch of the US-French satellite TOPEX-Poseidon in 1992, space-based surface navigation has been uninterrupted, followed by a number of satellites, including the current Jason-3.
The sea level is affected by water heating and cooling, and scientists can use high-altitude data to detect weather conditions such as warm El Nino and cool La Nina.
It is important to measure the overall rise in sea level due to global warming, which scientists have warned, and scientists have warned that it is a threat to the world’s beaches and billions of people.
“Our planet is a highly interconnected dynamic system between land, ocean, ice, the atmosphere, as well as our human society, and that system is changing,” said Karen Saint-Germain, director of the Global Science Department at the US Space Agency. Report on Friday.
“Because 70 percent of the Earth’s surface is the ocean, oceans play a huge role in the transformation of the entire system,” he said.
The new satellite may have unprecedented accuracy.
“This is a very important parameter in climate control,” Joseph Ashbacher, director of global monitoring at the European Space Agency, told the Associated Press this week.
“We know the sea level is rising,” Ashbacher said. The big problem is how fast and how fast.
Other instruments on the aircraft measure how the radio signal passes through the atmosphere, providing data on atmospheric temperature and humidity, which helps to improve global weather forecasts.
Europe and the United States are sharing $ 1.1 billion (€ 900 million) in missions, including dual satellites.
