Sentinel-6 Michael Freilich, the newest addition to a long line of ocean-monitoring satellites, becomes the reference satellite for sea level measurements.

PASADENA, Calif. (NASA PR) — On March 22, the newest U.S.-European sea level satellite, named Sentinel-6 Michael Freilich, became the official reference satellite for global sea level measurements. This means that sea surface height data collected by other satellites will be compared to the information produced by Sentinel-6 Michael Freilich to ensure their accuracy.

PARIS (ESA PR) — Sea-level rise is one of the most immediate consequences of climate change, as highlighted recently through urgent pleas from leaders of island nations at the COP26 summit. Global measures of sea-level rise are imperative to underpinning global policy and for strategies to protect coastlines and low-lying lands. Measuring tiny differences in the height of the sea surface from space is no easy task – but that’s exactly what the Copernicus Sentinel-6 Michael Freilich satellite is doing. And, after a year of exhaustive testing, this new mission is now delivering the world’s most accurate data on sea-level rise. 

WASHINGTON (NASA PR) — NASA and ESA (European Space Agency) have formed a first-of-its-kind strategic partnership to observe Earth and its changing environment. The global climate is rapidly changing and the demand for accurate, timely, and actionable knowledge is more pressing than ever. Recognizing that climate change is an urgent global challenge, the timing is right for NASA and ESA, as partners in space, to join forces to lead and support a global response to climate change. The partnership is an effort to help address and mitigate climate change through monitoring Earth with combined efforts of both agencies in Earth science observations, research, and applications.

Sentinel-6 Michael Freilich, the latest spacecraft to monitor sea surface height, releases its first science measurements to users.

PASADENA, Calif. (NASA PR) — After six months of check-out and calibration in orbit, the Sentinel-6 Michael Freilich satellite will make its first two data streams available to the public on June 22. It launched from Vandenberg Air Force Base in California on Nov. 21, 2020, and is a U.S.-European collaboration to measure sea surface height and other key ocean features, such as ocean surface wind speed and wave height.

PARIS (ESA PR) — In November 2020, the Copernicus Sentinel-6 Michael Freilich satellite was launched into orbit from the Vandenberg Air Force Base in California, US. Now, months later, the satellite has successfully passed what is known as the ‘in-orbit verification phase’, where its equipment is switched on and the instruments’ performance is checked.

Although the United Kingdom’s (UK) “Brexit” departure from the European Union (EU) on Jan. 1 will not affect its membership status in the European Space Agency (ESA), the nation’s participation in a number of European space programs is either ending or being curtailed.

On Christmas Eve, the UK and EU announced an agreement in principle that will govern trade, security and political relations after Brexit. Under the agreement, the UK’s participation in the:

• Galileo satellite navigation and European Geostationary Navigation Overlay Service (EGNOS) program will end;
• Copernicus Earth observation satellite program will continue, contingent upon a further agreement to be worked out next year; and
• EU Space Surveillance and Tracking (EUSST) program will end, although the Britain will continue to receive data as a non-EU country.

WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.

WASHINGTON (NASA PR) — Sentinel-6 Michael Freilich, a joint U.S.-European satellite built to measure global sea surface height, has sent back its first measurements of sea level. The data provide information on sea surface height, wave height, and wind speed off the southern tip of Africa.

DARMSTADT, Germany (EUMETSAT PR) — Three days after the launch of Sentinel-6 Michael Freilich from California, ESOC, ESA’s space Operations Centre, handed over flight operations of the Copernicus ocean-monitoring satellite to EUMETSAT.

BERN, Switzerland (RUAG Space PR) — With Saturday’s launch of ocean monitoring satellite Sentinel-6, two new Precise Orbit Determination Receivers (PODRIX) from RUAG Space made their maiden flight.

PODRIX achieves a very high, real-time in-orbit accuracy of the satellite’s position in orbit from below one meter to a few centimeters utilizing on-ground post-processing. The high accuracy is achieved through simultaneously processing of multi-frequency signals from the U.S. GPS and European Galileo satellites.
