Data from previous satellites show the rate of sea level rise is accelerating, according to mission scientists.<\/p>\n<p>Sentinel-6 Michael Freilich is the next in a series of oceanography missions tracking sea level rise, beginning with the U.S.-French Topex\/Poseidon mission that launched in 1992. The Jason 1, Jason 2, and Jason 3 satellites followed Topex\/Poseidon, and an identical satellite to Sentinel-6 Michael Freilich named Sentinel-6B is planned for launch in 2025 to further extend the data record of sea level rise.<\/p>\n<p>The Topex\/Poseidon and Jason satellites have charted about 3.5 inches (9 centimeters) of global sea level rise over the last 30 years, said&nbsp;Remko Scharroo, Sentinel-6 project scientist at Eumetsat.<\/p>\n<p>The cost of the two Sentinel-6 missions is roughly $1 billion, and was evenly divided between the U.S. and European partner agencies, according to Thomas Zurbuchen, head of NASA\u2019s science mission directorate.<\/p>\n<p>\u201cIt\u2019s the satellite so nice we built it twice,\u201d said Josh Willis, Sentinel-6 project scientist at NASA\u2019s Jet Propulsion Laboratory.<\/p>\n<p>\u201cThe record of global sea level rise actually goes back to the early \u201990s,\u201d Willis said. \u201cWhat\u2019s interesting about it is that you can see the rate of rise is actually increasing. In the \u201990s, sea level was rising at about 2 millimeters per year. In the 2000s, it was more like 3 millimeters per year, and now it\u2019s more like 4 or close to 5 millimeters per year. So we\u2019re watching the rate of sea level rise increase right before our very eyes, and it\u2019s satellites like this that allow us to do it.\u201d<\/p>\n<figure id=\"attachment_48782\" aria-describedby=\"caption-attachment-48782\" style=\"width: 1200px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-48782\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/Ice_lost_from_ice_sheets_contributes_to_sea-level_rise_pillars.jpg\" alt=\"\" width=\"1200\" height=\"848\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/Ice_lost_from_ice_sheets_contributes_to_sea-level_rise_pillars.jpg 1200w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/Ice_lost_from_ice_sheets_contributes_to_sea-level_rise_pillars-300x212.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/Ice_lost_from_ice_sheets_contributes_to_sea-level_rise_pillars-768x543.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/Ice_lost_from_ice_sheets_contributes_to_sea-level_rise_pillars-678x479.jpg 678w\" sizes=\"(max-width: 1200px) 100vw, 1200px\"><figcaption id=\"caption-attachment-48782\" class=\"wp-caption-text\">Artist\u2019s concept of the Sentinel-6 Michael Freilich satellite. Credit: ESA\/ATG medialab<\/figcaption><\/figure>\n<p>Craig Donlon, Sentinel-6 mission scientist at ESA, said rising sea levels \u201cthreaten&nbsp;major cities with increased flooding, including New York, London, Amsterdam, Tokyo, and more. It\u2019s estimated that about 2 to 3 million more people are exposed for every 1 millimeter rise in sea level.\u201d<\/p>\n<p>Sentinel-6 Michael Freilich is the eighth satellite to launch for the European Copernicus constellation, a fleet of orbiting sentinels observing Earth\u2019s land surfaces, oceans, ice sheets, and atmosphere with radar, optical, microwave, altimetry, and spectral instruments. The European Commission manages the Copernicus program, with ESA providing technical expertise and coordinating development of the Sentinel satellites.<\/p>\n<p>A primary goal of the Copernicus satellites is to collect data on Earth\u2019s changing climate. The fleet is the most capable satellite program focused on Earth observation. Data from the Sentinel satellites are distributed worldwide free of charge.<\/p>\n<p>\u201cWe see evidence of this dramatic change in many different measurements and events around the world, but they all point in the same direction \u2014 the Earth is warming,\u201d Donlon said in a pre-launch news conference. \u201cAnd the greatest indicator of this Earth system imbalance is sea level rise. That\u2019s because it integrates the total impact of global warming. That\u2019s dominated by the ice sheets melting, the thermal expansion of the sea water, and changes in terrestrial water storage.\u201d<\/p>\n<p>The Sentinel-6 Michael Freilich spacecraft carries a European dual-frequency Poseidon 4 radar altimeter that transmits signals toward the ocean surface more than 800 miles below the satellite. A receiver measures the time it takes for the signal to bounce off the ocean and return to the satellite.<\/p>\n<p>A microwave radiometer provided by NASA measures atmospheric properties that can introduce minuscule effects on the travel time of the radar altimeter signal, allowing scientists to correct for the perturbations and obtain a more precise measurement of sea level.<\/p>\n<p>Sentinel-6 Michael Freilich also carries instruments to help determine its exact location using GPS navigation signals, Doppler measurements, and laser tracking.<\/p>\n<figure id=\"attachment_48783\" aria-describedby=\"caption-attachment-48783\" style=\"width: 1000px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-48783\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/SeaLevel.jpg\" alt=\"\" width=\"1000\" height=\"475\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/SeaLevel.jpg 1000w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/SeaLevel-300x143.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/SeaLevel-768x365.jpg 768w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2020\/11\/SeaLevel-678x322.jpg 678w\" sizes=\"(max-width: 1000px) 100vw, 1000px\"><figcaption id=\"caption-attachment-48783\" class=\"wp-caption-text\">This chart illustrates the sea level rise observed by satellites since the early 1990s.

It will cover about 95 percent of the world\u2019s oceans every 10 days.<\/p>\n<p>The unusual house-like shape of the spacecraft itself is also an important factor in its performance. Engineers designed it for simplicity, and its lack of articulating solar array wings and other structures \u201cmakes for a very stable satellite design, which is really important for a satellite altimeter mission,\u201d Donlon said.<\/p>\n<p>Sentinel-6 Michael Freilich will take its measurements with higher resolution than earlier satellites looking at sea level rise. That means the new satellite will be able to better see how rising sea levels are impacting coastlines.<\/p>\n<p>Eumetsat will take over regular operations of Sentinel-6 Michael Freilich for its planned five-and-a-half year mission after it completes a three-day activation timeline.<\/p>\n<p>Ground teams will maneuver Sentinel-6 Michael Freilich into position flying about 140 miles, or 230 kilometers, behind the Jason 3 satellite \u2014 which launched in 2016 \u2014 for about a year\u2019s worth of cross-calibration to ensure the new spacecraft provides the same reliable data as its predecessor.<\/p>\n<p>Sentinel-6B will replace Sentinel-6 Michael Freilich after it launches in 2025, extending the sea level rise data record through at least 2030.<\/p>\n<p>SpaceX tentatively plans to reuse first stage that flew with the Sentinel-6 Michael Freilich mission Saturday on the company\u2019s next launch of a NASA spacecraft from Vandenberg next July, NASA launch director Tim Dunn said in a recent interview with Spaceflight Now.<\/p>\n<p>On that flight, a Falcon 9 rocket will launch NASA\u2019s Double Asteroid Redirection Test, or DART, mission from Vandenberg. It will mark the first time a NASA science mission has launched on a previously-flown Falcon 9 booster.<\/p>\n<p>DART is scheduled for launch in a window opening July 2021, allowing the probe to reach its asteroid target in late 2022. DART will intentionally crash into a tiny moonlet orbiting asteroid Didymos to test out deflection techniques that scientists could use to move an asteroid off a collision course with Earth.<\/p>\n<p>Dunn said NASA\u2019s Launch Services Program, which manages launch procurement and preparations for NASA science missions, has approved the rocket reuse plan for the DART mission, pending post-flight inspections and refurbishment on the booster after the Sentinel-6 Michael Freilich mission.<\/p>\n<p>NASA has already approved launches of SpaceX\u2019s Dragon space station cargo ships on previously-flown Falcon 9 boosters, and the agency earlier this year agreed to launch Crew Dragon astronaut missions on reused rockets beginning with the next SpaceX crew flight in March 2021.<\/p>\n<p>One caveat to the booster\u2019s future is its possible use as a backup for the SpaceX Crew-2 mission in March. Kathy Lueders, head of NASA\u2019s human spaceflight directorate, said last week that the Falcon 9 first stage from the Sentinel-6 Michael Freilich mission could be a backup for the Crew-2 launch if problems arise with the primary rocket assigned to astronaut mission.<\/p>\n<p>NASA and SpaceX have agreed to use the same booster for the Crew-2 launch that sent the Crew-1 mission toward the International Space Station on Nov. 15. That stage landed on a SpaceX drone ship in the Atlantic Ocean and returned to Cape Canaveral on Thursday with a lean after it apparently slid across the deck of the vessel in high winds or rough seas.<\/p>\n<p>The booster otherwise appeared to be in good shape, and SpaceX offloaded the rocket from the drone ship for transport to a hangar at Cape Canaveral for inspection and refurbishment.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A Falcon 9 rocket lifts off from Vandenberg Air Force Base with the Sentinel-6 Michael Freilich oceanography satellite.
