Blastoff of the Space Exploration Technologies booster occurred at 9:17 a.m. from Space Launch Complex-4 on South Base into fog-free skies.
With liftoff set for today at 17:17 GMT (18:17 CET, 09:17 PST), the Copernicus Sentinel-6 Michael Freilich satellite is poised for liftoff - atop a Falcon 9 rocket on the launch pad at the Vandenberg Air Force Base in California, US.
The Sentinel-6 Michael Freilich satellite was photographed before it was encased in a Falcon 9 missile casing, on November 3, 2020.
Sentinel-6 Michael Freilich is the first of two satellites jointly developed by a group of agencies in the United States and Europe, including NASA, NOAA, the European Space Agency, Eumetsat and the European Commission, to provide precise measurements of rising sea levels.

Europe and the United States are sharing the 900-million-euro ($1.1-billion) cost of the 10-year mission, which includes the launch of an identical twin, now called Sentinel-6B, in 2025. Sentinel-6 will be placed in orbit at an altitude of 1,336 meters, replacing Jason-3, the older generation.
They are created to last for five-and-a-half years, but could provide data for far longer. Jet Propulsion Laboratory at scientific briefing.
The satellite will collect data that can be used to improve weather forecasting, track hurricanes and climate models, such as humidity and atmospheric temperature. That instrument is similar to those on the six COSMIC-2 satellites launched in June 2019. That will assist in the commissioning of the new spacecraft, a process that will take about a year, said Remko Scharroo, project scientist for the mission at Eumetsat. It still now provides observations of global ocean terrain.
While the spacecraft features improved resolution and precision compared to its predecessors, scientists emphasized the importance of continuing a series of measurements of sea level height dating back almost three decades.
Each Sentinel-6 probe carries a radar altimeter, which measures the time it takes for radar pulses to travel to Earth's surface and back again.More news: Reuters tally: Europe's COVID-19 cases surpass 15 million mark
"It's a critical observation for a number of reasons, but its power is really unleashed when we combine our altimetry observations of the sea surface height measurements with the observations we get from the other satellites in the NASA fleet and the global fleet", she continued.
Global sea levels are rising 0.13 inches annually - 30% more than when the first mission was launched in 1992, according to NASA.
Accelerating sea level rise is arguably the climate change impact that will affect the largest number of people over the next three decades.
This mix of estimations will show the amount of ocean level ascent comes from dissolving ice sheets, and how much from ocean rise comes from sea development because of generally speaking sea warming, said Karen St. Germain, overseer of NASA's Earth science division, in an instructions zeroed in on the mission's science return.
Together with our global and interagency partners, we're monitoring the causes of sea level rise with high accuracy and precision.More news: NCB raids comedian Bharti Singh and husband's flat in Mumbai
" This failure on Monday reminded us how risky the space business is", Aschbacher said.
