 in order to understand better the improvements made by Cepollina. The amount of engineering and effort required to do work in space were surprising for the engineers in the early days of the manned space program. For instance, the astronauts Eugene Cernan and Thomas Stafford who were launched into space aboard Gemini 9 on June 3, 1966 had to deal with unimagined difficulties as soon as Cernan began a space walk. The plan called for Cernan to take some photographs and enjoy weightlessness

. He perspired enough to fog his helmet visor, and sweat pooled in his eyes . He ripped an insulating layer in the back of his suit, and he instantly felt the fierce, bare sunshine; he returned to Earth with painful burns.

Cepollina marks that "the experiences of NASA's first space walkers pioneered a lot of the technologies we use today." First of all, these initial attempts made clear the need for a change in space-suit design. The Gemini 9 astronauts wore suits inflated to 14 pounds per square inch

 because that's about normal pressure on earth. NASA cut the level to 4 PSI, reducing the feeling of working inside an overinflated balloon. Furthermore, a new training was developed for moving about in space: practice sessions underwater since moving in a liquid resembles the effects of weightlessness. However, the main challenge was conquering the exhaustion that Cernan had encountered. Cepollina states that their solution was to come up with power tools they could use to limit fatigue, and in order to reduce fatigue, an engineer in Cepollina's team, Paul Richard

In-orbit servicing
In his article "In-Orbit Servicing", Cepollina states that in the late 1960s, as inflation and constrained budgets limited the space program, NASA determined three ways of reducing costs: standardized spacecraft components; use of the same spacecraft to do several missions; and use of the Shuttle

 Systems to define the most cost effective mode for using the space shuttle. The companies identified four different methods of “renewing” the defective spacecraft:
  • Launch replacement satellites on conventional booster
  • Launch replacement satellites by shuttle
  • Launch replacement satellites by any of the methods mentioned above and retrieve the defective one for ground refurbishment by Shuttle
  • Replace the malfunctioning system of the defective satellite in orbit by Shuttle


When the costs of these four methods were compared, in-orbit servicing was found to be the lowest.

What are the changes that comes with in-orbit servicing? On the other hand, such an approach called for a totally different spacecraft design. In this new concept, each subsystem occupied its own separate drawer or removable module in the spacecraft. For example, all the components having to do with supplying power (the power unit of the space craft) would make up one module so that if something wrong happened with the power unit, that part of the spacecraft was easily taken out and renewed.

In-orbit serviced satellites

From his early days with NASA, Cepollina has worked on engineering solutions for satellites and spacecraft. In the late 1960s, satellite failure was becoming a significant problem, and engineers at NASA, including Cepollina, began working on a new type of Multimission Modular Craft. As described by Cepollina, these crafts would have swappable parts and could potentially be fixed easily by space-walking astronauts.

 satellite, launched in 1980 to conduct astronomical observations of the sun. When it began to fail several months into orbit, Cepollina was asked to lead the repair mission, begun in 1984. The mission the first of its kind was a success; the modular craft concept proved effective. Cepollina was lauded for his leadership on the project and was subsequently named Satellite Servicing Project Manager.

. The mission he undertook has widely been cited as the most difficult on-orbit repair mission ever attempted. Having worked on the development of its modular design, as well as its command and control subsystem, Cepollina knew the Hubble well. However, few could have anticipated that the Hubble, launched in 1990 and orbiting 375 miles above the Earth, would have such a simple but crucial problem: a flawed mirror. NASA officials were appalled and embarrassed to discover that the contractor responsible had a miscalculation that made the telescope incapable of coming to a sharp focus.

This unexpected problem was too serious to fix by simply swapping out a defective module, so Cepollina became project manager of a hurriedly assembled team charged with repairing the telescope. "The first Hubble repair mission took us to the next level of servicing", he said. His team designed new optical elements that could correct the Hubble's flawed vision yet also fit in with the modular instrument design philosophy. Cepollina's leading additional successful repair and improvement missions for Hubble followed in 1997, 1999 and 2002. These additional missions enhanced the satellite so that the technologies which were not available at the time of Hubble's initial deployment, including better cameras, more efficient solar arrays, and a more powerful processor

Inventions applied in other fields

Not only has Cepollina's work benefited the advancement of space technology, but it has also led to improvements in several other industries including a much more accurate method to detect breast cancer

 that uses technology originally developed for Hubble's charge coupled device (CCD). Other improvements are smaller and faster microchips created with highly sophisticated Hubble-type optics, and manufacturing applications employing an intelligent, programmable, hand-held power tool.

Cepollina as a team leader

In addition to being a successful inventor, Cepollina is also a team leader. His work with the Hubble highlights his character as a leader. He is currently the manager of NASA's Hubble Space Telescope Development Project at the NASA Goddard Space Flight Center in Greenbelt, Maryland. Among his numerous awards, Cepollina received the NASA Outstanding Leadership Medal for the Hubble Space Telescope First Servicing Mission.
