Skylab's impending demise in 1979 was an international media event, [150] with T-shirts and hats with bullseyes [9] and "Skylab Repellent" with a money-back guarantee, [151] wagering on the time and place of re-entry, and nightly news reports.
NASA expected that the Shuttle would be ready by 1979, and Skylab would not re-enter until the early 1980s. Another factor was that, in 1975, it was decided not to launch a second Skylab ; this gave a boost to Skylab re-use plans. As it was, the Shuttle was not ready until the early 1980s, and Skylab's orbit decayed in 1979. [5]
On August 15, 1978, Smith accepted a one-year assignment as deputy associate administrator for Space Transportation Systems at NASA Headquarters, Washington, D.C. He served as director of the Skylab Task Force appointed by the NASA administrator to represent NASA preceding and following the reentry of Skylab.
On July 11, 1979, the US Skylab space station (77,100 kilograms [170,000 lb]) reentered and spread debris across the Australian Outback. [76] The reentry was a major media event largely due to the Cosmos 954 incident, but not viewed as much as a potential disaster since it did not carry toxic nuclear or hydrazine fuel.

Heavy solar activity was a factor in causing the earlier-than-expected atmospheric reentry of Skylab in 1979. [9] Data from solar cycle 20 was used to build the K-1974 solar proton fluence model, used for planning space missions during solar cycle 21. [10]
Efforts by non-NASA professionals led to clear results. First, if Skylab had come down on or near a major city, the two-hour warning would have risked an urban panic. That panic would have been more dangerous than the satellite reentry. Second, Skylab was projected to break up to some 5,000 lethal pieces. A danger to man, animal, and airplane.
She was a guidance and navigation controller for Skylab and monitored its de-orbiting and re-entry in July 1979. Afterward, she returned to her payload operator role, preparing for the upcoming STS-1 Space Shuttle mission. [3] [4]
