"Jack Kinzler, Skylab’s Savior, Dies at 94"

Obituary excerpt...

Mr. Kinzler saved (Skylab) with a parasol.

When Skylab shed its shield, most of the proposed solutions entailed a spacewalk, with all its inherent dangers. To Mr. Kinzler, that was an unattractive prospect: The commander of Skylab’s crew, Charles Conrad Jr., known as Pete, was his next-door neighbor and friend.

What was needed, Mr. Kinzler knew, was a fix that could be done from the inside. He learned that Skylab had an airlock — a narrow passage meant for use as a camera port — near the site of the damage. It might be possible, he thought, to build a kind of flat, collapsible shade tree, which could be extruded through the airlock and, once outside, made to bloom.

He phoned a sporting-goods store and ordered a set of fiberglass fishing rods. The salient thing about them was not that they caught fish, but that they telescoped.

To build his prototype, Mr. Kinzler arranged four rods like the ribs of an immense umbrella, securing one to each side of a piece of parachute silk roughly 24 feet square. Folded, the parasol would just fit into the airlock. Once extruded, its canopy could be snapped open by means of springs.

Normally, Mr. Kinzler said in interviews, the design, building and approval of such novel equipment might take NASA six months. His parasol was ready in six days — six days in which he and his staff of more than 100 lived, worked and slept in the Johnson Space Center.

 

The finished parasol, built from telescoping aluminum tubes and silver-and-orange fabric of nylon, Mylar and aluminum, was stowed aboard the crew’s Apollo spacecraft. At 9 a.m. on May 25, the crew — Commander Conrad, Joseph P. Kerwin and Paul J. Weitz — took off from the John F. Kennedy Space Center in Florida.

Just before midnight they docked with Skylab, where the interior temperature was approaching 130 degrees Fahrenheit; wearing spacesuits, they could work there for short periods.

On May 26, after ensuring the station was free of hazardous gases, crew members pushed the parasol through the airlock and released the canopy. It did not open fully — it remained partly puckered — but in the end that did not matter.

Over the next few days, Skylab’s inside temperature fell to a companionable 70 degrees. Shedding their suits, the astronauts completed their 28-day mission.

For his work, Mr. Kinzler received the Distinguished Service Medal, NASA’s highest honor.

By the time he saved Skylab, Mr. Kinzler was already an experienced unfurler. In the late 1960s, as the United States raced to put a man on the moon, NASA officials asked him to suggest what that man might do to mark the occasion once he got there.

Plant a flag, Mr. Kinzler said, and leave a plaque.
