ЦитатаAug 22, 2020 16:46Weather 70% GO for Wednesday's launchThe initial forecast from Launch Weather Officer Will Ulrich for Wednesday's 2:16 a.m. EDT (0616 UTC) launch of the Delta IV Heavy and on the NROL-44 mission indicates a 70 percent chance of favorable conditions.Tropical Storm Laura is forecast to move into the Gulf of Mexico by mid-week, pulling some moisture away from east-central Florida for the Delta IV Heavy launch countdown on Tuesday night."As a result, decreasing precipitation chances are expected on Tuesday, with afternoon showers and thunderstorms focusing over the central and western portions of the peninsula during MST Roll. With continued onshore flow and adequate moisture, isolated showers over the Atlantic are expected to push toward the coast both Tuesday and Wednesday nights. Therefore, the primary concern for both the launch and 24-hour delay windows is the Cumulus Cloud Rule," the launch weather team says.The operations forecast includes scattered low- and high-level clouds, a chance of isolated showers, good visibility, easterly winds 10 to 16 knots and a temperature near 81 degrees F.If the launch is postponed to Thursday for some reason, there is an 80 percent chance of good conditions.

ЦитатаAug 24, 2020 17:16Launch Readiness Review CompletedThe Launch Readiness Review (LRR) has given the "go" to continue preparations for Wednesday's early morning liftoff of the United Launch Alliance (ULA) Delta IV Heavy rocket on the NROL-44 mission for the National Reconnaissance Office (NRO) and U.S. Space Force.Liftoff is scheduled for [color=]2:16 a.m. EDT[/color] (0616 UTC) from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida.The LRR, led by ULA Launch Director Lou Mangieri, was completed this morning in the Delta Operations Center (DOC) at the Cape and virtually via teleconferencing.Leadership from ULA, the NRO and the Space Force assessed the readiness of the rocket and mission assets, discussed the status of pre-flight processing work, heard technical overviews of the countdown and flight, and previewed the weather forecast that continues to be favorable with a 70 percent chance of acceptable conditions.At the conclusion of the meeting, senior leaders were polled and gave a unanimous ready status for launch, then signed the Launch Readiness Certificate.The National Reconnaissance Office (NRO) is an Intelligence Community element and Department of Defense organization responsible for developing, acquiring, launching and operating America's reconnaissance satellites, as well as operating associated data processing facilities in support of national security. Using NRO data, the National Security Agency, National Geospatial-Intelligence Agency, and other NRO mission partners produce intelligence products for the President, Congress, national policymakers, warfighters, and civil users.United Launch Alliance will offer live comprehensive countdown coverage from the Delta Operations Center (DOC) in our automatically-refreshing blog beginning Tuesday evening at 5:30 p.m. EDT (2130 UTC), with continuing commentary all the way to liftoff.
ЦитатаUnited Launch Alliance to Launch NROL-44 Mission to Support National SecurityCape Canaveral Air Force Station, Fla., (Aug. 24, 2020) - A United Launch Alliance (ULA) Delta IV Heavy rocket is in final preparations to launch the NROL-44 mission for the National Reconnaissance Office (NRO) to support national security. The launch is on track for Aug. 26 at Space Launch Complex-37 from Cape Canaveral Air Force Station. Launch is planned for 2:16 a.m. EDT. The live launch broadcast begins at 1:55 a.m. EDT on Aug. 26 at www.ulalaunch.com."ULA is proud of the long-standing history of supporting critical national security missions and the continued partnership with our mission partners," said Gary Wentz, ULA vice president of Government and Commercial Programs. "Only the Delta IV Heavy possesses the capability to deliver this unique mission to orbit due to a combination of heavy lift and the largest flight-proven payload fairing." The Delta IV Heavy is the nation's proven heavy lifter, delivering high-priority missions for the U.S. Space Force, NRO and NASA. The vehicle also launched NASA's Orion capsule on its first orbital test flight and sent the Parker Solar Probe on its journey to become the fastest robot in history while surfing through the sun's atmosphere.This Delta IV Heavy is comprised of three common core boosters each powered by an Aerojet Rocketdyne RS-68A liquid hydrogen/liquid oxygen engine producing a combined total of more than 2.1 million pounds of thrust. The second stage is powered by an AR RL10B-2 liquid hydrogen/liquid oxygen engine.This will be the 41st launch of the Delta IV rocket, and the 12th in the Heavy configuration. To date ULA has launched 140 times with 100 percent mission success.With more than a century of combined heritage, ULA is the nation's most experienced and reliable launch service provider. ULA has successfully delivered 140 missions to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field, deliver cutting-edge commercial services and enable GPS navigation....
