PASADENA, Calif. (KESQ) – As Southern California braces for what forecasters are calling a severe El Niño, a pair of satellites are watching the weather that unfolds. Sentinel 6 and Sentinel 6B, orbiting some 800+ miles above the Earth, constantly stare at our oceans. Every ten days, they're able to map about 95% of them. In doing so, they can sense the changes that are fueling El Niño. Scientists at NASA's Jet Propulsion Laboratory, or JPL, explained how it all works. "[The satellites] send a radar wave down to the ocean and wait for it to bounce back up. And they just time how long it takes to go down and come back," said Josh Willis, a climate scientist with JPL. The vertical position of the satellites remain constant as they orbit the Earth. By knowing the position of the satellite in space and the time it takes for the radar waves to bounce back and forth, researchers can determine the average height of the water in a given area. Each radar beam essentially maps a big circle on the ocean. The circle is about 10 kilometers, or 6 miles, in diameter. The heights of the top and bottom of...

Every hurricane season has one moment that worries forecasters most. It comes when an ordinary storm turns dangerous within a day or two. Sometimes it takes less time than that. A pair of satellites now circling Earth 30 seconds apart is gathering data that could help forecasters spot the conditions behind that dangerous turn. The two spacecraft are named Sentinel-6 Michael Freilich and its newer counterpart, Sentinel-6B. Both spend their days making precise measurements of the height of the ocean. NASA and its European partners, including the European Space Agency and EUMETSAT, launched Sentinel-6B last November. The goal was to sharpen hurricane forecasts, protect coastal infrastructure and help industries such as shipping. The new satellite now trails its older partner by half a minute. Together the two are gathering precise sea-level readings of what oceanographers expect to become a historic El Niño. El Niño was slow to strengthen El Niño is a natural swing in the Pacific Ocean. It happens every few years, when the water along the equator runs warmer than usual, and it reshuffles weather patterns around the planet as it does. Its cooler counterpart, La Niña, tends to push weather the other way. This year’s El Niño...

SpaceX is targeting Wednesday, September 16 for a Falcon 9 launch of the USSF-259 mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California. The four-hour launch window opens at 6:00 p.m. PT. This will be the 13th flight for the first stage booster supporting this mission, which previously launched Sentinel-6B, Twilight, NROL-172, Transporter-17, and eight Starlink missions.

Sentinel-6B satelit pruža precizna mjerenja razine mora, ključna za predviđanje uragana i razumijevanje El Niña. Podaci spašavaju živote.
