Цитата: ESARAMPING UP TO LAUNCH SENTINEL-6Written by MARIANGELA20 October 2020With less than a month to go before a SpaceX Falcon 9 takes Copernicus Sentinel-6 Michael Freilich into orbit, preparations are forging ahead at the launch site.Sentinel-6 team during battery testing (Credits: ESA)After the satellite was unpacked, it underwent a series of tests to make sure that nothing had been damaged during transportation. Then the capacity of the two batteries has been tested: they were charged and discharged in three shifts (day, late and night shift) for a total of 20 hours.Once the team completed the capacity test, the spacecraft has been powered up to charge the batteries and update the software. The team has used the opportunity to also test telemetry links to ESA's European Space Operations Centre (ESOC) in Germany and to test the GPS connections.[color=#607d8bChecking GPS signals (credits: ESA)[/color]All in all a great achievement for the team with everything working.The launch campaign team in front of the satellite (Credits: ESA)After resting for the weekend, the team started with new energies for the important steps ahead.First, the Poseidon instrument has been checked to ensure it would perform as expected. Meanwhile the launcher Payload Attach Fitting (PAF) has been brought into the clean room ready to be mated to the Payload Adapter (PLA), which will allow the team to perform the first umbilical line measurements.Then it's been time for another big milestone on the way to launch: a performance check of the radar altimeter that actually measures the sea level. The main instrument has been switched off for the last time: next switch-on will be once the satellite is in orbit and it will stay on for the whole mission!Performance check on the radar altimeter (Credits: ESA)Tasks still to tick off the 'to do' list before Sentinel-6's 10 November launch date include the hazardous job of fuelling the satellite, as well as encapsulating it in the rocket fairing and rolling it out to the launch pad. We're getting closer!From the ESA Sentinel-6 launch campaign team in Vandenberg.Read more about the Copernicus Sentinel-6 mission.

ЦитатаSpinning and moving Sentinel-6 prior to fuelling Доступ по ссылке European Space Agency, ESA29 окт. 2020 г.In preparation for liftoff on 10 November, the Copernicus Sentinel-6 Michael Freilich satellite has been fuelled. The video shows the satellite being spun around on its frame and then moved out of the cleanroom. The satellite was subsequently fuelled. Everything went very smoothly, with the team completing this somewhat hazardous task in just one day. The fuelling team followed up to check that there were no leaks and then sealed the fill and drain valves.The next task is to join the satellite to the launch adapter before it is finally encapsulated in the Falcon 9 rocket fairing. Liftoff from the Vandenberg Air Force base in California has been confirmed for 19:29:39 GMT (20:29:39 CET) on 10 November. Скрытый текст: Once safely in orbit, Copernicus Sentinel-6 will continue the long-term record of reference sea-surface height measurements that were started in 1992 by the French-US Topex Poseidon satellite and then by the Jason series of satellite missions. The mission comprises two identical satellites launched five years apart. Firstly, Copernicus Sentinel-6 Michael Freilich launching in few weeks, and then Copernicus Sentinel-6B in 2025 to supply measurements until at least 2030.Since sea-level rise is a key indicator of climate change, accurately monitoring the changing height of the sea surface over decades is essential for climate science, for policy-making and, ultimately, for protecting those in low-lying regions at risk.The Copernicus Sentinel-6 mission is a true example of international cooperation. While Sentinel-6 is one of the European Union's family of Copernicus missions, its implementation is the result of the unique collaboration between ESA, NASA, Eumetsat and NOAA, with contribution from the French space agency CNES.Credits: NASA

ЦитатаNov. 6, 2020Preparing the Sentinel-6 Michael Freilich Satellite for LaunchInside SpaceX's Payload Processing Facility at Vandenberg Air Force Base in California, the U.S.-European Sentinel-6 Michael Freilich ocean-monitoring satellite is being encapsulated in its payload fairing on Nov. 3, 2020. Sentinel-6 is scheduled to launch on Nov. 21, 2020, at 12:17 p.m. EST, atop the SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Air Force Base. A U.S.-European partnership, the Sentinel-6 Michael Freilich spacecraft will begin a five-and-a-half-year prime mission to collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. The mission will also collect precise data of atmospheric temperature and humidity that will help improve weather forecasts and climate models.The spacecraft is named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and a tireless advocate for advancing satellite measurements of the ocean. Sentinel-6 Michael Freilich builds on the heritage of the European Space Agency's Copernicus Sentinel-3 mission as well as the heritage and legacy of the U.S.-French TOPEX/Poseidon and Jason-1, 2, and 3 series of sea level observation satellites. Launched in 2016, Jason-3 is currently providing data initiated with the observations of TOPEX/Poseidon in 1992. The data from these satellites has become the gold standard for sea level studies from space over the past 30 years. In 2025, Sentinel-6 Michael Freilich's twin, Sentinel-6B, is scheduled to launch and advance these measurements for at least another half decade.Image Credit: NASA/Randy BeaudoinLast Updated: Nov. 6, 2020Editor: Yvette Smith
ЦитатаNov. 6, 2020Sentinel-6 Michael Freilich Prepared for LaunchThe Sentinel-6 Michael Freilich satellite is encapsulated in a protective nosecone, or payload fairing, at Vandenberg Air Force Base in California. The fairing will sit atop a SpaceX Falcon 9 rocket that will launch the satellite into Earth orbit in the late-November 2020.Credits: NASA/Randy BeaudoinWith a little over two weeks to go until its California launch, the Sentinel-6 Michael Freilich spacecraft is undergoing final preparations. Technicians and engineers have encapsulated the satellite in the payload fairing - the protective nosecone that will ride atop the SpaceX Falcon 9 rocket. The launch is targeted for Nov. 21."We're almost there," said project manager Parag Vaze of NASA's Jet Propulsion Laboratory in Southern California. "Soon, we'll be watching the satellite on its journey into Earth orbit 830 miles above our planet." Project manager Pierrik Vuilleumier of ESA (European Space Agency) echoed the sentiment.About the size of a small pickup truck, Sentinel-6 Michael Freilich will play a central role in efforts to track sea level rise caused by climate change. What's more, the data that it collects on sea level variations near coastlines will provide information to support coastal management and with planning for floods, while its atmospheric measurements will enhance weather and hurricane forecasts.Sentinel-6 Michael Freilich is one of two identical satellites that are a part of the Sentinel-6/Jason-CS (Continuity of Service) mission, a U.S.-European collaboration. The mission is part of Copernicus, the European Union's Earth observation program managed by the European Commission. Continuing the legacy of the Jason series missions, Sentinel-6/Jason-CS will extend the records of sea level into their fourth decade, collecting accurate measurements of sea surface height for more than 90% of the world's oceans, and providing crucial information for operational oceanography, marine meteorology, and climate studies. Sentinel-6 Michael Freilich's twin, Sentinel-6B, is scheduled to launch in 2025.Technicians and engineers working on the Sentinel-6 Michael Freilich satellite pose in front of the spacecraft in its protective nosecone, or payload fairing, at Vandenberg Air Force Base in California. Once closed, the fairing will sit atop a SpaceX Falcon 9 rocket, launching in late November 2020.Credits: NASA/Randy BeaudoinMore About the MissionSentinel-6/Jason-CS is being jointly developed by ESA, the European Organisation for the Exploitation of Meteorological Satellites, NASA, and the National Oceanic and Atmospheric Administration, with funding support from the European Commission and technical support from France's National Centre for Space Studies.JPL, a division of Caltech in Pasadena, is contributing three science instruments for each Sentinel-6 satellite: the Advanced Microwave Radiometer, the Global Navigation Satellite System - Radio Occultation, and the Laser Retroreflector Array. NASA is also contributing launch services, ground systems supporting operation of the NASA science instruments, the science data processors for two of these instruments, and support for the U.S. members of the international Ocean Surface Topography Science Team.The Sentinel-6 Michael Freilich press kit:https://www.jpl.nasa.gov/news/press_kits/sentinel-6/Jane J.
