Вот в такой ситуации ремонтный робот на ГСО и нужен.
Подлетел бы и дёрнул

наверное этим ребятам проще еще одну дергалку для СБ возить с собой, на случай глюков  :roll:

Ну а если всё нормально будет - зачем она? Лишняя масса только, и лишние затраты.
Там же на ГСО полно аппаратов рядышком, сделать одну-две универсальных "дёргалки" с функциями заправки, проверки и т.д., и летать потихоньку между разными КА.

Там основные кучки в зонах над США, над Европой и над индокитаем, так что даже далеко летать не придётся.

ну про дергалки я пошутил конечно, а вот про прочность - это более чем реально

New Intelsat satellite will only receive partial power

Officials expect the Intelsat 19 communications satellite will suffer permanent performance degradation from a damaged solar array which finally popped loose in June after early attempts to deploy the panel failed.
 
The satellite's south solar array stayed folded against the spacecraft following its deployment from a Sea Launch Zenit 3SL rocket June 1. The north solar array unfurled as planned.

Intelsat confirmed the solar panel unfurled June 12, and engineers began activating the satellite's communications payload to determine how much of the craft's original mission could be accomplished.

All of Intelsat 19's communications antennas have deployed, officials said.

The communications firm announced last week that data received from Intelsat 19 indicate the south solar array is damaged, and the power available to the satellite will be reduced.

The satellite was manufactured by Space Systems/Loral of Palo Alto, Calif.

Intelsat said sufficient power is available to operate Intelsat 19's Ku-band and C-band payloads. The satellite carries 34 Ku-band and 24 C-band transponders.

Intelsat 19 was intended to distribute video and television services across the Asia-Pacific region from a position along the equator at 166 degrees east longitude. The craft was built to replace the Intelsat 8 satellite launched in 1998.

Officials expect the Intelsat 8 satellite will remain in service through the end of 2019, and Intelsat says there will be no interruption in service.

The satellite and the launch were insured, according to Intelsat.

The company expects Intelsat 19 has enough fuel to maneuver the satellite for approximately 15 years, which was the craft's intended design lifetime.

Testing of the satellite's communications payload will be completed by mid-July, Intelsat said.

Engineers are studying what caused Intelsat 19's solar array trouble, and the investigation's focus so far is on an unexpected, isolated event which registered on microphones and pressure sensors during ascent inside the payload fairing of the Sea Launch Zenit 3SL rocket.

The signature resembles an event observed on the 2004 launch of the Telstar 14/Estrela do Sul 1 communications satellite, another craft built by Space Systems/Loral which failed to deploy one of its solar panels.

Other Space Systems/Loral spacecraft on Sea Launch missions have had no solar array difficulties.

Independent Board Formed to Investigate Sea Launch Anomaly[/size]
Posted by Doug Messier
on September 14, 2012, at 6:18 am

PALO ALTO, CA and BERN, SWITZERLAND (SS/L & Sea Launch PR) — Space Systems/Loral (SS/L) (NASDAQ: LORL) and Sea Launch AG today announced the formation of a three person Independent Oversight Board to oversee the ongoing investigation into the root cause of an anomaly on a recently launched satellite. The Independent Oversight Board will be made up of impartial industry experts, nominated by the two companies.

The Independent Oversight Board will guide the joint SS/L-Sea Launch investigation team, which has been working together for several weeks to collect and analyze data with the objective of determining the root cause of damage to one solar array on an SS/L 1300 satellite that was launched on May 31, 2012 on a Sea Launch Zenit-3SL vehicle.

Instrument data showed an unexpected, isolated event around 72 seconds after liftoff, which registered on sensors on the rocket. Following the launch, SS/L and Sea Launch each conducted independent investigations to examine and analyze spacecraft and launch vehicle build records, ground test data and flight telemetry data, including readings from accelerometers, pressure sensors, and microphones in the payload compartment. Those analyses identified no shortcomings in the build quality or ground testing, but so far have not identified the root cause of the anomaly.

"Space Systems/Loral has had many successful launches on the Sea Launch Zenit rocket beginning in 2003," said John Celli, president of SS/L. "We always enjoy working with the Sea Launch team and we see this as an opportunity to ensure our mutual success going forward. Together we are determined to uncover the source of this anomaly."

"Sea Launch and Space Systems/Loral agree that forming an independent oversight board will greatly benefit our joint efforts to identify the root cause," said Kjell Karlsen, president of Sea Launch AG. "Our relationship with Space Systems/Loral is strong and we are committed to working together in assuring satellite operators and the insurance community that any risk has been mitigated."

The Independent Oversight Board and the joint SS/L-Sea Launch team will continue to work together over the coming weeks to consolidate the results of their independent investigations and to identify additional analyses and tests to be performed. With the Independent Oversight Board driving the effort, the goal will be to identify the root cause of the anomaly within three months' time.[/size]

Sea Launch Prepares To Set Sail with IS-19 Damage still a Mystery
By Peter B. de Selding

PARIS — Launch services provider Sea Launch AG is preparing to launch Eutelsat and Intelsat satellites in December and January even as it works to unravel the mystery of what caused substantial damage to a Space Systems/Loral-built Intelsat satellite that Sea Launch orbited in May, Sea Launch President Kjell Karlsen said.

 "There's got to be something" in the telemetry from the May launch that would indicate why the Intelsat IS-19 satellite separated from the Sea Launch upper stage with severe damage to one of the solar arrays, Karlsen said in a Sept. 10 interview here during World Satellite Business Week, organized by Euroconsult. "But so far we have gone through all our data and couldn't find anything that is out of specification."

 Following an initial Sea Launch investigation that found no rocket-related anomalies, Luxembourg- and Washington-based Intelsat agreed to proceed with the mid-August launch of the IS-21 satellite, which was built by Boeing Space and Intelligence Systems of El Segundo, Calif. The launch was a success.

 Paris-based Eutelsat is scheduled to launch its Eutelsat 70B telecommunications satellite aboard a Sea Launch rocket for early December, and Sea Launch said Sept. 20 that the Zenit 3SL rocket's Block DM upper stage arrived at Sea Launch's home port in Long Beach, Calif., on Sept. 19.

 Intelsat is set to launch its IS-27 satellite, also built by Boeing, in January on a Sea Launch Zenit.

 The fact that Intelsat and Eutelsat, respectively the largest and third-largest commercial fleet operators, would agree to move forward with Sea Launch with the blessing of their insurance underwriters is an indication that insurers and satellite owners believe the IS-19 solar-array damage may be the result of a lack of compatibility between the Space Systems/Loral (SS/L) 1300 satellite bus and the environment inside the Sea Launch fairing.

 This theory is reinforced by the fact that a similar incident occurred in 2004, when the SS/L-built Telstar 14/Estrela do Sul-1 satellite was released in orbit by Sea Launch with massive solar-array damage. Then as now, Sea Launch and SS/L found nothing pointing to anomalies in either the rocket or the satellite.

 Satellite operators and insurance underwriters eventually put aside the issue, and SS/L and Sea Launch moved on. Sea Launch orbited seven SS/L-built satellites since then, before the May launch.

 Karlsen said neither Bern, Switzerland-based Sea Launch nor Palo Alto, Calif.-based SS/L will let it drop this time around.

 "I can tell you that we're going to push this as far as we can," Karlsen said. "I've spoken to John [Celli, SS/L's president] several times and we're in lockstep on this. SS/L and Sea Launch teams are meeting three times a week on this."

 The two companies have appointed a three-member independent oversight board to review the investigation, which up to now has been run by SS/L and Sea Launch, with the participation of Intelsat. The companies hope that with this added layer of experts looking at the problem, a root cause of the anomaly will be discovered.

 Karlsen declined to say how long SS/L and Sea Launch would maintain an active investigation, which can be costly for both companies. In addition to the cost — Sea Launch is paying for its share of the investigation and related analyses performed by Boeing Commercial Space Co., which builds the Sea Launch payload accommodation structures and the rocket's fairing. He allowed as how the May incident occurred at a particularly bad time for Sea Launch, which he said had begun to regain the consideration of the market after a 2007 failure and subsequent Chapter 11 bankruptcy reorganization.

SSL And Sea Launch Announce Successful Completion Of Investigation
by Staff Writers
Palo Alto, CA (SPX) Dec 21, 2012

Space Systems/Loral (SSL) and Sea Launch AG have jointly reported that the Independent Oversight Board (IOB) formed to investigate the solar array deployment anomaly on a satellite launched in the spring of 2012 has reached a unanimous conclusion.

The IOB, which was comprised of three highly regarded industry experts, worked with a comprehensive team of engineers from both SSL and Sea Launch to conduct an exhaustive investigation of data from the launch vehicle, the spacecraft, and interactions between the two.

Extensive data provided by Sea Launch were instrumental in achieving the findings which led to the investigation's positive conclusion.

The IOB concluded that the anomaly occurred before the spacecraft separated from the launch vehicle, during the ascent phase of the launch, and originated in one of the satellite's two solar array wings due to a rare combination of factors in the panel fabrication.

While the satellite is performing on orbit, the anomaly resulted in structural and electrical damage to one solar array wing, which reduced the amount of power available for payload operation.

After rigorous investigation, the launch vehicle was exonerated from causing or contributing to the anomaly and there were no unexpected interactions between the spacecraft and the launch vehicle. Both SSL and Energia Logistics Ltd. (ELUS), on behalf of Sea Launch, concurred with the IOB findings.

"SSL and Sea Launch worked together to form the independent review board to ensure that the cause of the anomaly was identified without any bias, preconception or prejudice," said John Wormington, chairman of the IOB.

"Both companies were extremely cooperative in providing the data and analyses that we required, and worked well together in solving this very elusive problem. We have very high confidence in the conclusion."

"I'd like to thank the highly qualified oversight board for conducting this extensive and thorough investigation," said John Celli, president of SSL.

"It was imperative to both ourselves and Sea Launch that we fully understand the cause of the anomaly, and we can now clearly say that interactions between the satellite and launch vehicle were not contributing factors. SSL is already taking actions to assure mission success for all upcoming launches."

"The findings of the IOB have validated that the launch vehicle did not cause or contribute to the observed anomaly," said Kjell Karlsen, President of Sea Launch AG.

"I wish to thank our partners for their dedicated support of the investigation, and contributions of in-depth knowledge and understanding of the launch vehicle design, spacecraft launch environments and integration analyses."

Karlsen continued, "Sea Launch is pleased to have had the opportunity to assist SSL in finding a definitive cause of the anomaly and looks forward to performing many more launches of SSL satellites."
