Four Polar Orbiting Satellites Launched by NASA


To enhance the weather forecast system and Earth observations, NASA has launched four advanced polar-orbiting satellites to space. The satellites were launched on the third try. First, two launches which were conducted earlier in this week got canceled due to heavy winds and boats inside the restriction zone of the launch area.

The JPSS-1, Joint Polar Satellite System -1 launched from Vandenberg Air Force Base, California at 1:47 a, PST. It was lifted off by a United Launch Alliance Delta II rocket.
Stephen Volz, director of NOAA’s Satellite and Information Service, said “Launching JPSS-1 underscores NOAA’s commitment to putting the best possible satellites into orbit, giving our forecasters — and the public — greater confidence in weather forecasts up to seven days in advance, including the potential for severe, or impactful weather.”

Once it reaches the orbit, it will be named as NOAA-20. First, it will go to check out and validation of its five advanced instruments for three months after that it will start operating. The satellite will join the joint Suomi National Polar-orbiting Satellite. After that, it will give valuable information on atmospheric temperature, the temperature of Sea surface, information about ocean color, sea ice cover and many more.

As per the report, the given data will enhance the weather forecasting system and the scientists will able to give more accurate information about the hurricane, post-storm recovery by visualizing the damages caused by the storm.

The Satellite is equipped with five upgraded instruments which will also help to evaluate accurately about climate patterns which influence weather such as EI Nino and La Nina.
Louis W. Uccellini, director of NOAA’s National Weather Service, said, “Emergency managers increasingly rely on our forecasts to make critical decisions and take appropriate action before a storm hits.” He further stated, “Polar satellite observations not only help us monitor and collect information about current weather systems, but they provide data to feed into our weather forecast models.”
