Atmosphere of Triton asymmetry was actually observed during star occultations by Triton in 1990s. Before Voyager 2 arrived, a nitrogen and methane atmosphere with a density as much as 30% that of Earth had been suggested. This proved to be a great overestimate, similar to the predictions of the atmospheric density of Mars, but like on Mars, a denser early atmosphere is postulated. Voyager 2 flew past Triton five hours after closest approach to Neptune in mid-late August 1989. During the flyby, Voyager 2 took measurements of the atmosphere, finding methane and nitrogen in the atmosphere. In the 1990s, observations from Earth were
Gas-s-s-s and he only made one more movie before a twenty-year sabbatical. " A great deal of care went into what I was saying and how I was going to say it," he said of "Gas-s-s-s". "The finished picture does not evidently make all these points. It discourages me and so for a little while I prefer to step away ... Directing is very hard and very painful. Producing is easy. I can do it without really thinking about it." Corman did, however, go on to produce "Boxcar Bertha" for AIP. "Gas-s-s-s" found a fresh audience on late night television in
