NASA to launch new satellite on Saturday to track rising sea levels

Sentinel-6 is a heir of a line of satellites placed in orbit since 1992 to observe sea level.

A SpaceX Falcon 9 successfully launched November 21 the latest in a series of satellites developed by the United States and Europe to track rising sea levels.

The satellite is expected to launch on Saturday (Nov. 21) at 12:17 pm EST (9:17 a.m. local time and 1717 GMT) Space Launch Complex 4 at Vandenberg Air Force Base in California, On a five-year mission to map sea rise associated with global warming.

Should Saturday's launch need to be delayed for any reason, there are backup launch windows on each subsequent day, beginning 12 minutes earlier each day, according to NASA. You can watch the live coverage on NASA's public channel and NASA's youtube channel.

Rising sea levels are some of the most prominent signs of climate change.

"It's going to be a new star in the sky, giving us the best possible measurements of sea level rise, ocean waves and wind", Craig Donlon, Sentinel-6 mission scientist with ESA, said during a press conference on Friday. The island lost about 255 billion tons of ice on average per year during this period.

"We all know that (Earth) is undergoing enormous changes, extremely fast changes and changes we never had before on this planet with a speed and intensity caused, obviously, by humans", he said. Farther south in Los Angeles County, residents may catch a glimpse of the rocket's smoky trail as it powers the satellite into orbit, then reverses course and returns to Vandenberg for recovery and use in future missions.

Copernicus Sentinel-6 heads to launch pad.

According to public health data, California reported 11,835 new cases on Wednesday, the most in a single day since July. It follows the state's more sweeping lockdown in the spring that affected all residents, day and night.

Each Sentinel-6 probe carries a radar altimeter, which measures the time it takes for radar pulses to travel to Earth's surface and back again.

The Sentinel satellites are each about the size and shape of a large minivan topped with slanted solar panels, and weigh almost 1,200 kilos (2,600 pounds), including rocket fuel.

"It's a critical observation for a number of reasons, but its power is really unleashed when we combine our altimetry observations of the sea surface height measurements with the observations we get from the other satellites in the NASA fleet and the global fleet", she continued.

Together with our global and interagency partners, we're monitoring the causes of sea level rise with high accuracy and precision.

The complexity of expectations is that sea level rise is not proceeding at the same rate around the world.

"Extreme sea level events that are historically rare - once per century in the recent past - are projected to occur frequently, at least once per year, at many locations by 2050", especially in the tropics, the United Nations climate science advisory panel, the IPCC, concluded in a major report last year.

Sentinel-6 won't be spoken to independently in items from the National Oceanic Atmospheric Administration (NOAA), however it will upgrade the models and guides NOAA and different accomplices in the mission as of now produce to all the more likely shield world populaces safe from increasing tropical storms, delegates said. While the group can't eat in cafés not surprisingly, they are as yet doing group building exercises, for example, open air porch gatherings and joint exercise, additionally outside, he said. "It energizes us and gives us the energy to continue moving forward".
