(Phys.org) -- Envision a space with more options and increased capacity: a place where aging and ailing satellites could place a service call for a helpful boost to the right orbit, a quick repair, or a fuel top-off to keep them operating longer. According to many of the speakers and attendees at NASAs Second International Workshop on On-Orbit Satellite Servicing, such long-discussed lifeline services are more than a dream of the future; they are options that could be achievable within the next five years.

On May 30-31, more than 240 international representatives gathered at NASAs Goddard Space Flight Center in Greenbelt, Md., to discuss international near-term satellite servicing plans and delve into the issues that could either stimulate or strangle the emerging commercial servicing industry. During the event, NASA and the Canadian Space Agency (CSA) presented results to date from NASAs Robotic Refueling Mission on the International Space Station.

We were very excited to see such a diverse gathering of satellite manufacturers, fleet owners and operators, government representatives, and policy experts engaged in tackling the challenges to getting on-orbit satellite servicing off the ground, said Frank Cepollina, Associate Director of the Satellite Servicing Capabilities Office (SSCO) at Goddard.

The message from these discussions was very clear, he continued. Satellite fleet owners and operators want servicing capabilities. The technology to do these sorts of tasks is ready now. We believe its the right time to make routine and reliable satellite servicing in orbit a reality.

After welcoming remarks by Goddard Center Director Christopher Scolese, plenary speakers Kay Sears of Intelsat General, Dr. Robert Ambrose of NASA, and Prof. Henry Hertzfeld of George Washington University kicked off the event. They verbally painted a vision of a satellite-servicing-enabled world, describing the technology needed to get there, and explaining the various legal, financial, insurance and policy challenges to be navigated.

More than thirty-five speakers and session leaders gave presentations, led panel discussions, and took audience questions during the event. Queries ranged from How much would satellite owners profit from life-extension versus repair services, to, What sort of low-cost features could be implemented on satellites now to make servicing easier in the future? Speakers included representatives of governments and private industries, satellite bus manufacturers, and fleet owners and operators, as well as representatives of insurance, finance, law, and policy. Presentations from the event are available at the SSCO Workshop website.

Attendees often referred to the Five Rs of On-Orbit Servicing, or the ability to remotely survey, relocate, refuel, repair, and replace individual parts of satellites in space. Participants also discussed the sixth R related to satellite servicing: the perceived risk the first mission would, by its very nature, carry and ultimately alleviate. Attendees agreed that this is a challenge best suited for NASA to resolve.

While there has been strong interest in these sort of capabilities for decades, robotic satellite servicing in geosynchronous Earth orbit the space highway for weather and communication satellites has never before been attempted, said Benjamin Reed, Workshop Chairman and the deputy project manager of SSCO. Consistent with the United States Space Policy, NASA is actively investigating ways to remove the perceived risk and jumpstart a commercial industry to provide cost-efficient servicing solutions to satellite manufacturers, owners, and ultimately consumers.

Were encouraged by the success of the recent SpaceX Dragon launch, he continued, and are exploring how an initial shared government/commercial servicing mission could initiate a fully commercial satellite servicing capability for America.

NASA workshop discusses how On-Orbit Robotic Satellite-Servicing becomes reality

Excalibur Almaz Inc. (EAI) has successfully completed its Commercial Crew Development Round 2 (CCDev2) partnership with NASA's Commercial Crew Program. Through CCDev2, NASA is spurring innovation and development of safe, reliable and cost-effective spacecraft and launch vehicles capable of transporting astronauts to low Earth orbit and the International Space Station.

EAI, based in Houston, began exchanging technical information with NASA about its human spacecraft concept for low Earth orbit crew transportation in October 2011 under an unfunded Space Act Agreement (SAA). The company and NASA reviewed the design of the spacecraft, its systems requirements and compatibility with launch vehicle alternatives. Additional milestones included presentations on how the company plans to test and integrate its spacecraft in advance of a crewed launch. All of the EAI SAA milestones were completed by June 19.

"During this unfunded Space Act Agreement with EAI, NASA learned valuable information about how the company plans to upgrade the existing capsule with modern flight capabilities," CCP Manager Ed Mango said. "We commend the EAI team for completing all of their established milestones during this partnership."

EAI plans to upgrade human space capsules built and tested decades earlier with new internal systems and a service module. The spacecraft can accommodate three crew members and accompanying cargo during trips to low Earth orbit. It will consist of a reusable reentry capsule, launch abort system and expendable service module. EAI plans to outfit the spacecraft with the ability to land on the ground, rather than in the ocean.

"The interchange of technical information between the EAI team and the NASA Commercial Crew Program during the past year has been a very positive and important step toward the completion of our commercial transportation system," said Buckner Hightower, EAI chief executive officer. "NASA's feedback related to clarification of commercial crew transportation requirements was of significant assistance to support our efforts to provide safe, reliable and cost effective space transportation for both commercial and government customers."

All of NASA's industry partners continue to meet their established milestones in developing commercial crew transportation capabilities.
