Watch SpaceX launch a satellite that will monitor the world’s oceans

Saturday morning NASA plans to launch the Sentinel-6 satellite which is expected to help scientists better measure sea levels among other weather and climate patterns. File

The satellite is required to dispatch Saturday (Nov. 21) at 12:17 p.m. EST (9:17 a.m. nearby time and 1717 GMT) Space Launch Complex 4 at Vandenberg Air Force Base in California, on a five-year journey to plan ocean rise related with a unsafe atmospheric devation.

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. Weather is reportedly 80 percent good for the launch but a backup launch is also scheduled for Sunday at 12:04 p.m EST (9:04 a.m PST).

SpaceX will launch its Sentinel-6 ocean-mapping satellite on Saturday.

The real value of Sentinel-6 data is that it allows small businesses or other service providers to develop added value to, in turn, develop services that can be sold or provided to others. actors, in particular all those related to the sea. Gravity Recovery and Climate Experiment Satellites (GRACE).

The new satellite will be followed by its twin Sentinal 6B five years later, and together they are tasked with extending NASA's three decade-long record of global sea surface height measurement.

"Because 70% of the Earth's surface is ocean, the oceans play an enormous role in how the whole system changes", she said.


Josh Willis, a Sentinel-6 project scientist at NASA, said the benefits from the Sentinel-6 data will flow to almost every sector affected by climate change, given that 90% of the heat trapped by human-emitted greenhouse gases ends up in the ocean. NASA's Jet Propulsion Laboratory manages the agency's contribution to the mission.

While measurements are also taken at ground level, in harbors and other coastal areas, they don't provide the same precise uniform standard as a single satellite sweeping the entire globe every 10 days, he said. Today's sea level rise is approaching 5 millimeters per year, more than twice the annual rate of rise drawn in the 1990s.

Accelerating sea level rise is arguably the climate change impact that will affect the largest number of people over the next three decades.

"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.

This mix of estimations will show the amount of ocean level ascent comes from dissolving ice sheets, and how much from ocean rise comes from sea development because of generally speaking sea warming, said Karen St. Germain, overseer of NASA's Earth science division, in an instructions zeroed in on the mission's science return. While space satellites have been tracking this in detail for 30 years, the roots of this problem begin in the Industrial Revolution, when nations began burning huge reserves of carbon through coal, oil and other natural resources to power their economies.

After launch, Sentinel-6 will fly 30 seconds behind Jason-3.

The event can be watched live at space.com via NASA TV or on NASA TV's YouTube channel.
