Charting sea level from space

Satellite images of our planet have become essential to our survival, offering a new outlook of our world. With rising seas being one of the biggest threats to society, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.

Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage. Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch.

This documentary explains how measurements are taken from the top of the White Mountains to make sure users get the best data on sea height from satellite altimetry.

It features interviews with Craig Donlon, Head of ESA’s Earth Surfaces and Interior Earth and Mission Science Division and Stelios Mertikas, Director of Laboratory of Geodesy & Geomatics Engineering at the @Technical University of Crete.

ESA highlights 2020

2020 has been another year of progress for ESA. The launch and commissioning of Solar Orbiter heralded a new era of space science, whilst Eutelsat Konnect revolutionised telecommunications. The new Vega SSMS began a cost-effective new launch system for small satellites, deploying exciting new technologies such as PhiSat and ESAIL. ESA’s Earth Observation activities were also showcased, with the launch of Sentinel-6 and an international effort to monitor the environmental and economic impact of COVID-19. Gaia and Cheops yielded new findings about our universe; ESA astronaut Luca Parmitano returned successfully from orbit. With a lunar programme agreement signed and new steps being taken to control debris, ESA is set to begin 2021 at the forefront of space exploration.

Copernicus Sentinel-6 ready for launch

Final preparations are underway in California for the launch of Sentinel-6 Michael Freilich, a joint European and US satellite designed to take precise measurements of sea-level change. The satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ a radar altimeter to map sea-surface topography. The satellite will provide fundamental data for climate science and policymaking, helping to protect the 600 million people who live in vulnerable coastal areas. It will also deliver near-realtime information for marine and weather forecasts.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French space agency CNES. Scheduled for launch on 21 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base on the California coast, the satellite is named Michael Freilich after NASA’s former Director of Earth Science.

Copernicus Sentinel-6 measuring sea levels using radar altimetry

This November the newest member of the EU’s Copernicus programme, Sentinel-6 Michael Freilich, will take to the heavens from Vandenberg Air Force Base in California. The satellite is named after NASA’s former Director of Earth Observation and is a radar altimetry mission to monitor sea-level rise, wave-height and windspeed.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French space agency CNES. It will continue a three-decade-long time-series of radar altimetry missions that started with the Topex-Poseidon mission and was then followed by the Jason missions.

Copernicus Sentinel-6 Michael Freilich: preparing for launch

A European satellite built to carry out precise measurements of sea level changes has arrived in California in preparation for launch. The Sentinel-6 Michael Freilich satellite forms part of the European Union’s Copernicus Earth Observation programme and will employ radar to map sea surface topography.

The mission will be used to monitor the height of the sea surface to understand long-term change. It will also measure wave height and wind speed. The satellite will provide fundamental data for climate science, policy-making and protecting the 600 million people who live in vulnerable coastal areas.

Data are provided to Copernicus services in near-real time to improve marine and weather forecasts used by maritime and coastal communities.

The mission is a collaboration between ESA, the European Commission, EUMETSAT, NASA and NOAA, with support from the French Space Agency CNES.

It is named Michael Freilich after NASA’s former Director of Earth Science and is scheduled for launch on 10 November on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base.

Resupply Mission Wraps Up at The Space Station on This Week @NASA – January 31, 2020

A resupply mission wraps up at the space station, a new name for an Earth-observing satellite, and preparing for an unprecedented peek at the Sun … a few of the stories to tell you about – This Week at NASA!

This video is available for download from NASA’s Image and Video Library: https://images.nasa.gov/details-NHQ_2020_0131_TWAN_Resupply%20Mission%20Wraps%20Up%20at%20The%20Space%20Station%20on%20This%20Week%20@NASA%20%E2%80%93%20January%2031,%202020

ESA Preview 2020

The year 2020 will see new and exciting European space missions, from journeys to the Sun and back to Mars, and from innovative telecommunications satellites to the continuing operation of Copernicus Earth observation satellites. The second ExoMars mission will see a European rover on the ‘Red Planet’ and the ESA/NASA Solar Orbiter mission will be launched around the Sun. This year marks probably the last time an ESA astronaut flies on a Russian Soyuz spacecraft – future European astronaut flights are likely to be on the new US spacecraft, in particular the NASA Orion vehicles, which feature European-built Service Modules, now being prepared for flights to the Moon and beyond. The year also sees the first flight of ESA’s new Vega-C launcher from Europe’s Spaceport in French Guiana, where Ariane 6 operations are also taking shape for its first flight.

ESA highlights 2019

As the year comes to a close, it is once again time to look back and reflect on some of the achievements and highlights of European spaceflight. The new Gaia star catalogue and the launch of Cheops are keeping ESA at the forefront of space science, as will Solar Orbiter, being prepared for launch next year. The Copernicus programme continues to be the largest Earth observation programme in the world, with ESA preparing even more missions. On the Space Station, Luca Parmitano became the third European to command an ISS expedition. During his second mission, he made some of the space programme’s most complex and demanding spacewalks. At the end of 2019, the ESA Space19+ ministerial conference agreed to give ESA its largest budget ever and expressed continued support for Europe’s independent access to space with Ariane 6 and Vega-C.

Sentinel-6: charting sea level

In a cleanroom in Ottobrunn, Germany, the latest Copernicus Sentinel satellite is ready for final testing before it is packed up and shipped to the US for liftoff next year. Designed and built to chart changing sea level, it is the first of two identical Sentinel-6 satellites that will be launched consecutively to continue the time series of sea-level measurements. This new mission builds on heritage from previous ocean topography satellites, including the French–US Topex-Poseidon and Jason missions, previous ESA missions such as the ERS satellites, Envisat and CryoSat, as well as Copernicus Sentinel-3. With millions of people around the world at risk from rising seas, it is essential to continue measuring the changing height of the sea surface so that decision-makers are equipped to take appropriate mitigating action – as is being currently highlighted at the COP-25 Climate Change Conference in Spain.
