Interplanetary spacecraft capable of interstellar travel is becoming real

Gordon Shumway is an alien from the planet Melmac who follows an amateur radio signal to Earth and crash-lands into the garage of the Tanners, a suburban middle-class family who live in the San Fernando Valley area of California. The family consists of social worker Willie (Max Wright), his wife Kate (Anne Schedeen), their teenage daughter Lynn (Andrea Elson), younger son Brian (Benji Gregory), and pet cat Lucky, whom ALF wishes to consume. Willie gives Gordon the nickname ALF ("Alien Life Form"), and, unsure what to do, the Tanners take ALF into their home to hide him from the Alien Task Force, a part of the U.S. military that specializes in aliens, and their nosy neighbors Trevor and Raquel Ochmonek (John LaMotta and Liz Sheridan), until he can repair his spacecraft. Though his culture shock, survivor's guilt, and loneliness often cause problems for the Tanners, as well as their fear of what could happen if others were to discover his existence, they grow to care for and love him as a part of the family. Later it is revealed that ALF's home planet, Melmac, exploded due to nuclear war, leaving him and other survivors of his species without a home, and that he survived its destruction because he was away as part of the Melmac Orbit Guard.[7] In the season one episode "Pennsylvania 6-5000", ALF tries to convince the President of the United States to stop the nuclear program, as he fears that Earth could suffer a similar fate to Melmac, though a misunderstanding causes the President and national security to call the FBI to arrest Willie. Episodes dealt with ALF learning about Earth and making new friends both in and out of the Tanner family, including Willie's brother Neal (Jim J. Bullock); Kate's widowed mother Dorothy (Anne Meara), with whom ALF has a love-hate relationship; her boyfriend and later husband Whizzer (Paul Dooley); the Ochmoneks' nephew Jake (Josh Blake); the psychologist Larry (Bill Daily); and the blind woman Jody (Andrea Covell), who never learns of ALF's true nature, but does know through touch that he is short and hairy. Changes occur in the Tanner household over the course of the series, including the birth of a new child, Eric, who was added to the series because Anne Schedeen was pregnant at the time; ALF moving from the laundry room to the attic, which he and Willie convert into an "apartment", and the death of Lucky in the season four episode "Live and Let Die", which ALF accepts despite having previously attempted to catch and eat him due to having come to love and respect him. When ALF adopts a new cat with the intention of eating it, he grows fond of it and allows the Tanners to adopt it. In the 1996 movie Project ALF, which follows ALF after his capture by the USAF, the Tanners do not appear due to moving to Iceland.
