Atlas V DMSP-19 Launch Highlights

[Старый]

Ну что, куда на этот раз улетел Центавр?

[DAP]

Ради любопытства можно у знатоков поинтересоваться, рекорд ли это по части запуска спутника после хранения (18-20 лет после производства)? Были ли аналогичные ситуации у нас или у них? И как эффективно сейчас могут работать компоненты, произведенные в 1993 году, то есть реально какие-то аппаратные и программные средства из глубоко 80-х? Или для мониторинга погоду ничего более эффективного не требуется?

Bodnar tells the story:
"This satellite was built in the mid 90s. There's components that were made as early as 1993. It was turned over to the Air Force as finished in 1998 and put into long-term storage for 10 years.
"The satellite itself was originally built in (East Windsor,) New Jersey. When it was finished it was shipped to California and put into storage in Sunnyvale. In 2008, it was brought out of storage."
Along the way it underwent two lifetime extension efforts to boost the in-space life expectancy, upgraded with star trackers and a digital gyroscope for navigation and replacement of materials and lubricants that had degraded over time. And there has been testing -- lots of testing -- on Flight 19.

А что значит 

The satellite apparently hit a snag in one of its first post-launch tasks when it unfurled its solar array.

ВВК, гуглом переводили?  
Это означает "спутник, по видимому, столкнулся с проблемой, выполняя одну из первых задач после выведения, когда разворачивал солнечную батарею".

 С ним коварным. Спасибо что перевели, а то там у меня звучало :

Спутник-видимому врезался     в препятствие в одном из своих первых задач после запуска, когда она развернула свою солнечную батарею.

У этих спутников от времени появляется такая наклонность - делать бадабум.  DMSP-F11 тоже разорвало.

USAF weather woes grow as DMSP-19 stops obeying orders
by Mike Gruss — March 3, 2016

WASHINGTON — NOAA satellite operators unexpectedly lost the ability to command one of the Air Force's primary weather satellites on Feb. 11 and now officials from both organizations are racing to determine if the spacecraft can return to service, officials told SpaceNews.
The satellite, known as the Defense Meteorological Satellite Program Flight 19, is used to help weather forecasters predict fog, thunderstorms and hurricanes that could impact military operations. Launched in April 2014, the spacecraft is the Air Force's newest weather satellite on orbit.
Air Force officials do not yet know the cause of the problem, or if the satellite can be recovered, Andy Roake, a spokesman for Air Force Space Command, said in a March 2 email.
"Operators lost the ability to command and control Defense Meteorological Satellite Program Flight 19 (DMSP F-19) Feb. 11, 2016 and subsequently are making attempts to regain connectivity," he said. "The satellite is in a stable configuration while operators continue to troubleshoot the anomaly.
"At this time, it is not known what caused the anomaly or if the satellite will be recovered, and the anomaly is under investigation. There are no other known issues with the satellite."
Air Force Space Command disclosed the problem with the satellite March 2 in response to questions from SpaceNews.
The DMSP constellation requires at least two primary satellites and two backup satellites to gather cloud imagery. As a result of the problem, the Air Force has reassigned an older satellite, DMSP Flight 17, which launched in 2006 and had been serving as a backup, into a primary role, Roake said.
"There is no impact to the strategic weather mission, and the DMSP constellation remains able to support warfighter requirements," Roake said. "The constellation continues to provide weather and atmospheric data to users as it has for the past five decades."
DMSP operators in Suitland, Maryland, working for the National Oceanic and Atmospheric Administration, first recognized trouble with the satellite when they could not "establish command access" with the satellite on Feb. 11, NOAA officials said in a Feb. 12 email obtained by SpaceNews.
Workers initially attributed the problem to the ground system, but then discovered a problem with the "RF receive subsystem" when its temperature spiked 10 degrees. Without that subsystem "the ability to uplink real time commands and refresh operational and navigation loads is lost," the email said.
About four hours later the Air Force declared a state of spacecraft emergency and on the next four contacts with the satellite, "all attempts to restore command access failed," the email said.
Roake said March 2 that operators are working through a 30-day plan to recover the command and control capability and that it is "premature to consider end of life shutdown actions at this time."
"The satellite is still sending signals; DMSP engineers continue to receive telemetry from F-19 and are able to verify the health and status of the vehicle," he said.
But, he added, any data from the satellite is no longer being used for weather forecasting. In addition, Air Force officials expect a gradual decay in that data in the 60 days following a problem.
The Air Force still has five DMSP satellites, Flights 14 – 18, operating in primary or backup roles. The oldest satellite, Flight 14, launched in 1997.
Even the potential loss of DMSP Flight 19 is likely to renew questions about the health of the Air Force's weather satellite program.
In February 2015, DMSP Flight 13, exploded on orbit after a problem with its battery. In addition, after much debate, Congress opted last year not to launch the next satellite in the DMSP program Flight 20, and instead chose to terminate the DMSP program. That decision meant the Air Force is not expected to launch another weather satellite until 2017 at the earliest and that satellite, a technical demonstration from the Operationally Responsive Space Office, would not provide the same kinds of weather data as the DMSP satellites.
Lockheed Martin Space Systems of Denver is the prime contractor on the DMSP program. Matt Kramer, a Lockheed Martin spokesman, referred questions to the Air Force.

With DMSP-19 sidelined by glitch, Air Force orders stay of execution for its twin
by Mike Gruss — March 15, 2016

WASHINGTON — A top U.S. Air Force official, worried because operators lost the ability to command a two-year-old weather satellite, has ordered its twin satellite to be kept in storage a while longer as a backup plan, even though Congress terminated the program in December
The Air Force's move raises questions about whether Congress would reconsider its decision and ask the military to launch the second satellite, known as Defense Meteorological Satellite Program Flight 20. Industry officials said lawmakers could discuss the situation at a March 15 House Armed Services strategic forces subcommittee hearing.
In December, Congress terminated the DMSP program and stripped funding for the Air Force to launch the Flight 20 satellite. That satellite, built by Lockheed Martin Space Systems, has been in storage in Sunnyvale, California, at a cost of about $40 million per year.
But on Feb. 11, Air Force and NOAA operators lost the ability to command its twin, already on orbit and known as DMSP Flight 19. That satellite, which launched in April 2014, is used to help weather forecasters predict fog, thunderstorms and hurricanes that could impact military operations. DOD leaders had planned to rely on the satellite through at least 2019.
Air Force officials do not yet know the cause of the problem, or if the satellite can be recovered.
But if DMSP-19 cannot be recovered, the Air Force wants to keep its options open. That could mean taking another look at launching DMSP-20.
Lt. Gen. Samuel Greaves, the commander of the Air Force's Space and Missile Systems Center, said in a March 14 email to SpaceNews that while the Defense Department still expects to complete the termination of the DMSP program by Dec. 20, DMSP-20 remains properly stored in Sunnyvale.
"As a result of the DMSP-19 anomaly, I directed the program office to take no irreversible action for the moment in order to allow the Air Force, DoD, and Congress an opportunity, if desired, to potentially evaluate the situation" he said.
Removing the satellite from its environmentally controlled storage facility is considered an irreversible action because of the payload contamination that would occur.
Greaves said the Air Force's schedule for disposing of DMSP-20 and closing the books on program by the December deadline calls for removing the satellite from storage by June 20. The Air Force has not said whether the satellite will be scrapped or given to museum.
Built in the 1990s, DMSP F-20, was penciled in for a 2020 launch even as the Air Force studied whether the cost — including additional years of storage — was worth it.
The study, completed in September 2014, recommended against launching the satellite. But the Air Force said in April 2015 that it intended to launch the satellite in 2018 to help offset the loss of Middle East-area coverage now provided by European satellite slated for retirement in 2017. But lawmakers, unhappy about the Air Force's weather satellite programs, opted not to fund the program in a massive spending bill in December, kicking off plans to dispose of the satellite.
DMSP F-20 has been a sore point with Rep. Mike Rogers (R-Ala.), the chairman of the House Armed Services strategic forces subcommittee. In January, he said the Air Force wasted $518 million on DMSP-F20 and that the Pentagon would have been better off burning the money in a parking lot.
Without DMSP-F19, the Air Force does not have a clear plan to gather cloud characterization and theater weather imagery data and are the Air Force's highest priority weather gaps.

DMSP-19 weather satellite dead after Air Force ends recovery effort

WASHINGTON — The Air Force has stopped trying to recover a two-year-old weather satellite after operators lost the ability to command the spacecraft last month, an Air Force spokesman said March 24.
Operators at the 50th Space Wing at Schriever Air Force Base in Colorado Springs, Colorado have "ceased all recovery efforts" of the Defense Meteorological Satellite Program Flight 19 satellite, Andy Roake, a spokesman for Air Force Space Command, said in a March 24 email to SpaceNews.
NOAA satellite operators unexpectedly lost the ability to command the Air Force's DMSP Flight 19 satellite on Feb. 11. The satellite, built by Lockheed Martin, is used to help weather forecasters predict fog, thunderstorms and hurricanes that could impact military operations. Launched in April 2014, the spacecraft is the Air Force's newest weather satellite on orbit and had a five-year design life.
In the last week, Gen. John Hyten, the head of Air Force Space Command, ordered the creation of a safety investigation board to look into the incident, Roake said. Further investigations are still possible.
Hyten warned a House subcommittee March 15 that he did not expect the satellite to return to operations.
The DMSP constellation requires at least two primary satellites and two backup satellites to gather cloud imagery. As a result of the problem, the Air Force has reassigned an older satellite, DMSP Flight 17, which launched in 2006 and had been serving as a backup, into a primary role.
