Mission managers polled “go” to begin fueling the SpaceX Falcon 9 with just under 40 minutes remaining until launch. Rocket Grade Kerosene, or RP1, now is loading into the SpaceX Falcon 9 rocket first stage booster, while liquid oxygen, or LOX, is loading into the rocket’s first stage. These propellants will power the stage’s nine […]
Live coverage is underway for launch of Sentinel-6B from Space Launch Complex 4 East at Vandenberg Space Force Base in California. Weather remains 90% favorable with thick clouds and cumulus clouds as the possible weather violations during the 12:21 a.m. EST (9:21 p.m. PST Sunday, Nov. 16) liftoff. Sentinel-6B is part of a series of […]
The launch of Sentinel-6B will continue a joint mission between NASA and its European partners to monitor sea levels. This data is key to helping improve public safety, city planning, and protecting commercial and defense interests. Along with measuring global sea level rise and ocean circulation, the satellites record vertical profiles of atmospheric temperature and […]
NASA and its launch partners are tracking several events during countdown and launch of Sentinel-6B aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California. Time | Events (all times are approximate): -00:43:00 | NASA launch manager propellant load and launch readiness poll-00:38:00 | SpaceX launch director verifies “go” for propellant load-00:35:00 […]
Coverage is underway for launch of the Sentinel-6B spacecraft, the newest international sea level measurement satellite mission jointly developed by NASA, ESA (European Space Agency), EUMETSAT (the European Organisation for the Exploitation of Meteorological Satellites), and the National Oceanic and Atmospheric Administration (NOAA), with funding support from the European Commission and technical support from the […]
The SpaceX rocket carrying the international Sentinel-6B satellite stands vertical on the launch pad at Space Launch Complex 4 East at Vandenberg Space Force Base in California. Liftoff is targeted for 12:21 a.m. EST Monday, Nov. 17 (9:21 p.m. PST Sunday, Nov. 16). Weather officials with the U.S. Space Force’s Space Launch Delta 30 predict […]
NASA, international partners, and SpaceX are moving forward with the launch of the Sentinel-6B satellite, which will measure sea levels, atmospheric temperature, and humidity worldwide. During the agency’s Launch Readiness Review at Vandenberg Space Force Base in California, NASA’s launch director and the launch team polled “go” for launch of Sentinel-6B. NASA will host a […]
Technicians are continuing launch preparations for Sentinel-6B, a satellite jointly developed by NASA and ESA (European Space Agency), that will measure sea level for nearly the entire globe, as well as atmospheric temperature and humidity ocean measurements. The team has completed nearly all their prelaunch milestones, including testing solar arrays, fueling the spacecraft, and encapsulating […]
Cardiac research, stem cell observations, and eye checks to ensure astronaut health wrapped up the week for the Expedition 73 crew aboard the International Space Station. The orbital residents also continued working on spacesuits and unpacked a pair of resupply ships rounding out their work week.
The Sun emitted a strong flare, peaking at 3:30 a.m. ET on Nov. 14. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured imagery of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. […]
