The sixth episode of the western series Wrangler is scheduled to air on NBC in the United States, starring Jason Evers as Pitcairn. Though TV Guide listings at the time indicate the episode was to air on this date, it is pre-empted for unknown reasons; as only an incomplete worktape exists in the UCLA archives, it’s possible that the reason for the delay was failure to complete the episode on time, possibly as a result of the series’ unprecedented method of shooting and editing on the then-very-new medium of videotape. Wrangler is produced by future Star Trek creator Gene Roddenberry, who also created this series, his first to get past the pilot stage; Roddenberry also wrote the episode (as indicated by the archived scripts), which would have been credited on screen to the pseudonym of “Leon Edward”. Though 1960 TV listings indicated that this episode was rescheduled for the following week, there is significant evidence that this episode was never actually broadcast, replaced by another episode which does exist archivally in finished form.

Voyager 1 emerges unharmed from what is considered the outer limit of the asteroid belt between Mars and Jupiter, having entered this 223,000,000-mile-wide zone of space in December 1977. Voyager 2 is expected to emerge similarly unscathed in late October 1978. NASA’s Pioneer 10 and 11 spacecraft had already demonstrated, in the early 1970s, that passage through the asteroid belt without mission-jeopardizing damage is possible. Both spacecraft are already imaging Jupiter from a distance of less than 180,000,000 miles, now meeting or exceeding the resolution of the best photos of Jupiter taken from Earth-based telescopes.

With the words “Prepare to joust, buzzard bait!”, Williams Electronics launches an arcade sleeper hit built on unlikely juxtapositions (medieval knights, jousting with lances, riding on ostriches, over a lake of lava, stalked by pterodactyls).
A memo from cable network TNT is leaked to the internet, revealing that the network’s programming executives are requesting an increase in sex and violence on the upcoming Babylon 5 spinoff series Crusade. A specific example from one episode is cited in which a telepath is lured into believing that a crewmember is a terrorist and acts rashly as a result; the network would prefer the telepath’s rash actions to be the result of a more straightforward (and less sci-fi-oriented) seduction scene. Series creator J. Michael Straczynski cryptically refuses to confirm or deny that the memo is real. The series has been in production for only four weeks, and won’t air until 1999.

Space Shuttle Atlantis lifts off on the 99th shuttle mission, a 12-day visit to the still-unoccupied International Space Station. Spacewalks and work in the station’s pressurized compartments make the final connections between the Russian-launched Zvezda service module and the rest of the station, and over three tons of supplies – most flown aboard Atlantis, but some contained in an unmanned Progress supply ship which has already automatically docked to the station – are transferred to the station. Atlantis’ 21st crew is Commander Terrence Wilcutt, Pilot Scott Altman, and mission specialists Daniel Burbank, Edward Lu, Richard Mastracchio, Yuri Malenchenko and Boris Morokov. In 2003, Lu and Malenchenko will return as the station’s seventh full-time residents.

The NASA/JPL Genesis mission, a 29-month trek through the solar system to gather solar particles and return them to Earth, ends in disaster when both of the parachutes – meant to slow the returning Genesis capsule down and give retrieval helicopters something to hook onto to bring the capsule to the ground safely – fail to open. As a result, the 420+ pound Genesis capsule slams into the Utah desert floor at nearly 200 miles per hour. The impact breaches not only the outer re-entry shell of the capsule, but the experiment canister within containing the fragile plates of gold, sapphire, diamond and other pure substances, all of which had been exposed to the solar wind to collect particles from the sun. Scientists begin picking through the debris to see what portions of those collection devices can be salvaged. Several pieces of the collection devices are salvageable, with at least two complete plates and fragments of several others, but many other plates are reduced to dust by the impact of landing.

NASA launches the unmanned OSIRIS-REx (Origins Spectral Interpretation Resource Identification Security Regolith Explorer) spacecraft, bound for the asteroid Bennu, a target it won’t reach for two years. Once at Bennu, OSIRIS-REx is intended to orbit the asteroid and then drop down close enough to gather surface samples for return to Earth in a small sample container capable of surviving re-entry through the atmosphere. The samples from Bennu, an asteroid considered a hazard for Earth in the future, will not arrive until September 2023.
