From the title page of the book:
Memory Alpha was the fabled "lost" adventure: published in limited numbers, the original was lost and the GDW library did not receive a copy. This text was made available through the efforts of archivists Paul Sanders and John Macek.
This short adventure was originally produced by Game Designers'
Workshop as a tournament adventure played at GenCon and Origins in 1984. A variant was produced for the T4 edition of Traveller (set in the early Imperium).
From the description inside the book:
This adventure is a Traveller tournament for any number of teams, each team consisting of eight characters. It is a single session scored adventure, which means that the team of players which best handles the situation (as scored by the referee) are the winners.
A synopsis of "The Situation":
Your group of travellers have spent years searching for the Rift Passage, "a path of refueling points which crosses the Great Rift". This discovery could be worth a fortune but your ship has been having issues with it's power plant. While looking for work to help pay for the repairs, the group encounters a well dressed patron who offers them a high paying mission. The only catch is he insists on a memory wipe on completion.
