Individuals dwelling in coastal communities or navigating treacherous waters will each profit from information flowing from the brand new Sentinel-6 Michael Freilich satellite tv for pc mission.
The satellite tv for pc is anticipated to launch Saturday (Nov. 21) at 12:17 p.m. EST (9:17 a.m. native time and 1717 GMT) House Launch Advanced four at Vandenberg Air Pressure Base in California, on a five-year quest to map sea rise related to world warming. Sentinel-6 will launch aboard a SpaceX Falcon 9 rocket. You possibly can watch it dwell right here on House.com, courtesy of NASA TV.
Climate is 80% go for the prime launch alternative on Saturday and a backup launch time on Sunday at 12:04 p.m. EST (9:04 a.m. native time and 1704 GMT). NASA held two media briefings Friday to debate the affect the brand new mission may have on present maps and fashions.

Sentinel-6 won’t be represented individually in merchandise from the Nationwide Oceanic Atmospheric Administration (NOAA), however it’ll improve the fashions and maps NOAA and different companions within the mission already produce to raised preserve world populations secure from intensifying hurricanes, representatives stated.
Sentinel-6 observations can be included in corresponding to sea wave forecasts (helpful for delivery merchandise throughout the ocean) and tropical storm predictions, to evacuate coastal populations shortly if the necessity arises.
As soon as Sentinel-6 finishes its one-year commissioning interval, anybody all over the world – together with educators, college students and different members of the general public – can obtain the uncooked information from the web site of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).
For researchers trying to enhance their local weather fashions, Sentinel-6’s work will simply mix with different science missions. For instance, the altimetry gathered from Sentinel-6 may very well be mixed with Earth’s gravity measurements from NASA’s Gravity Restoration and Local weather Experiment (GRACE) satellites.
This mixture of measurements will present how a lot of sea degree rise comes from melting ice sheets, and the way a lot from sea rise comes from ocean growth on account of general ocean warming, stated Karen St. Germain, director of NASA’s Earth science division, in a briefing targeted on the mission’s science return.

“Since 70% of the Earth’s floor is ocean, the oceans play an essential position in how the entire system [of global warming] modifications,” she stated. “These world modifications are creating each dangers and alternatives for our human communities.”
The advantages from Sentinel-6’s information will move to simply about each sector affected by local weather change, since 90% of the warmth trapped by human-emitted greenhouse gases results in the ocean finally, stated Josh Willis, Sentinel-6 mission scientist at NASA’s Jet Propulsion Laboratory, within the science briefing.
“We’re watching the speed of sea degree rise proper earlier than our eyes, and it is satellites like this that enable us to do it,” Willis stated. The speed of sea degree rise is accelerating, making it essential so as to add high-definition information from Sentinel-6 to current satellite tv for pc altimeters, he famous. Immediately’s sea degree rise is shut to five millimeters a 12 months, greater than double the annual rise price charted within the 1990s.
Complicating predictions is that sea degree rise doesn’t go on the similar price all over the world. Massive cities corresponding to New York Metropolis and Amsterdam are particularly liable to waters creating floods amongst their populations, stated Craig Donlon, Sentinel-6 mission scientist on the European House Company, in the identical briefing. Worse, he added, for each centimeter in sea degree rise, as many as three million extra folks worldwide are uncovered to flooding threats.
“The Earth is warming, and the best indicator is sea degree rise,” Donlon stated. Whereas area satellites have been monitoring that intimately for 30 years, the roots of this downside started within the industrial revolution, when nations started burning large reserves of carbon via coal, oil and different pure assets to energy their economies.
Whereas the scientists are wanting ahead to express outcomes from Sentinel-6, the launch groups are working to remain secure amid newer pandemic protocols corresponding to temperature checks whereas coming into buildings, bodily distancing between employees and quarantines after journey.
“There are worse issues than being trapped on the coast of California,” joked Tim Dunn, launch director of NASA’s launch providers program, through the information convention on Friday. Whereas the staff can’t dine in eating places as typical, they’re nonetheless doing staff constructing actions corresponding to out of doors patio conferences and joint train, additionally open air, he stated.
Morale stays excessive among the many group and Dunn stated he’s happy with all of the diversifications his colleagues are making. “It is good to return along with the staff, and to know the significance of what we’re doing,” he stated. “It does energize us and provides us the mandatory power to proceed to press ahead.”
