(Cape Canaveral Air Force Station, Fla., July 11, 2019) -- The United Launch Alliance (ULA) Atlas V rocket carrying the AEHF-5 mission for the U.S. Air Force Space and Missile Systems Center is delayed, due to an anomaly during component testing at a supplier which has created a cross-over concern. Additional time is needed for the team to review the component anomaly and determine if any corrective action is required to the launch vehicle. Launch of the AEHF-5 mission is now targeted for no earlier than Thursday, Aug. 8, 2019.

ЦитироватьULA delays Atlas 5 launch to August
July 11, 2019Stephen Clark

United Launch Alliance is pushing back its next Atlas 5 launch from Cape Canaveral until no earlier than Aug. 8, allowing time for engineers to ensure an unspecified anomaly during component testing at a supplier will have no impact on the Atlas 5's mission to place a U.S. Air Force communications satellite into orbit.

ULA announced the delay Thursday, citing "an anomaly during component testing at a supplier which has created a cross-over concern."

The Atlas 5 rocket was scheduled to lift off from Cape Canaveral next Wednesday, July 17, with the Air Force's fifth Advanced EHF communications satellite.

"Additional time is needed for the team to review the component anomaly and determine if any corrective action is required to the launch vehicle," ULA said in a brief statement.

United Launch Alliance did not identify which supplier or component were responsible for the delay, which follows a previous postponement from the Atlas 5's original target launch date of June 27 in order to replace a failed battery on the rocket.

ULA also did not announce a time for a potential launch attempt Aug. 8, but a countdown on that date is expected to have a two-hour window opening at approximately 5:50 a.m. EDT (0950 GMT).

The Atlas 5 rocket is fully assembled inside the Vertical Integration Facility, or VIF, at Cape Canaveral's Complex 41 launch pad. After the Atlas 5's first stage arrived at the VIF in May, workers installed the rocket's Centaur upper stage, five solid rocket boosters and the Atlas 5's payload shroud containing the Lockheed Martin-built AEHF 5 spacecraft.

The AEHF 5 satellite's launch comes after the launch of four previous AEHF spacecraft in 2010, 2012, 2013 and 2018, all on Atlas 5 rockets.

The U.S. military, the president and other government leaders rely on the AEHF network for secure video, voice and data communications. The AEHF satellites are hardened to operate in nuclear war and are resistant to jamming, providing reliable global links among strategic forces and commanders around-the-clock.

Military forces from Canada, the Netherlands and the United Kingdom also have access to the AEHF satellite network.

ЦитироватьВ США отложили два пуска ракет с военными спутниками
21:28

МОСКВА, 17 июл - РИА Новости. Пуски американских ракет-носителей Atlas-5 и Delta-4 с военными космическими аппаратами, планировавшиеся в июле, перенесены на август из-за технических проблем, сообщила компания United Launch Alliance (ULA).

В среду компания ULA, которая осуществляет пуски ракет Atlas-5 и Delta-4, сообщила о переносе с 25 июля на не ранее 22 августа старта ракеты Delta-4 со вторым навигационным спутником GPS-3 в интересах ВВС США с космодрома на мысе Канаверал.

В качестве причины отсрочки указана проблема, возникшая при наземном тестировании неназванного узла на предприятии одного из поставщиков. В связи с этим требуется дополнительное время для анализа ситуации, замены узла на ракете и его повторного тестирования.

Неделю назад компания ULA сообщила о переносе с 17 июля на не ранее 8 августа пуска ракеты Atlas-5 со спутником связи AEHF-5 также в интересах ВВС США и также с мыса Канаверал. При этом причина отсрочки была озвучена такой же, как и для Delta-4.

Ранее пуск ракеты Atlas-5 со спутником AEHF-5 уже откладывался из-за неисправной батареи на ракете.

Example of our Mission Success process. "Sibling issue": Part on the rocket is functioning normally. Another of the same part failed a test at a supplier.  This demands that all parts are suspect until we can prove otherwise. If we can't, C/A. Guilty until proven innocent...

One other item to consider: Atlas 5 rolls to the pad Tuesday morning & would be without shelter during a Falcon 9 launch attempt that evening. Launch pads are about 1.5 miles apart, but NOAA & NASA last year worried about exhaust contamination to GOES weather satellite's optics.

No such senstive optics on the AEHF-5 satellite launching Thursday, but it's a $1 billion-plus asset for the Air Force, which also hold the keys to the Eastern Range.

It could set up to be a busy week on the Space Coast.  SLC-41 (on the left), will host an early Thursday morning launch at 5:44am of #ULA's Atlas 551 with #AEHF5, while SLC-40 (between 39 A & B), will host #SpaceX #Falcon with #AMOS17 potentially as early as Tuesday at 6:52pm. https://twitter.com/ChrisG_NSF/status/1158100600715919360 ...

Weather is 70% GO for Thursday's launch

The first weather forecast for Thursday's Atlas V rocket launch was issued by meteorologists at Cape Canaveral Air Force Station's 45th Weather Squadron today, and the outlook is favorable for the early morning liftoff.

Launch Weather Officer Jessica Williams and her team expect a 70 percent chance of meeting the launch weather criteria during the two-hour launch window that opens at 5:44 a.m. EDT (0944 UTC). The primary area of concern will be the attached and detached anvil cloud rules.

"For the launch window early Thursday morning, a few showers and an isolated thunderstorm could linger over north Florida along the weak frontal boundary. With upper level winds from the west-northwest, this could cause a slight possibility of anvil clouds to reach the area during the window," today's L-minus 4 day forecast synopsis says.

At launch time, the forecast includes a few low-level clouds and scattered mid-level clouds, good visibility, southwesterly winds at the launch pad of 10-15 knots and a temperature near 78 degrees F.

"In the event of a 24 hour delay, conditions look even more favorable, with the primary concern remaining the anvil cloud rules from any lingering showers over north Florida from the remnants of the front," forecasters say.

The probability of favorable weather during Friday's launch window is 80 percent.

Obviously, that should have said "#AtlasV on Thursday."
