The eleventh Star Wars movie, Star Wars: The Rise Of Skywalker, premieres, starring Daisy Ridley, John Boyega, Adam Driver and Oscar Isaac, alongside original trilogy stars Mark Hamill, Billy Dee Williams, Ian McDiarmid, and Harrison Ford (Carrie Fisher appears pothumously in scenes originally filmed for, but cut from, The Force Awakens in 2015). Perhaps inevitably, given the late 2010s’ tendency to politicize popular culture and its followers, and with the weight of fan expectations of a satisfying conclusion to the saga on it, the film proves somewhat controversial. Shortly after its release, work on future Star Wars feature films at Disney-owned Lucasfilm comes to a halt, and the franchise becomes a mainstay of Disney’s streaming video service.

Boeing’s CST-100 Starliner space vehicle ends its uncrewed maiden voyage by successfully landing with its combination of parachutes and impact-cushioning airbags at White Sands, New Mexico. Intended to visit the International Space Station on its first flight, the Starliner’s flight plan changed unexpectedly when a software and sensor mishap during launch put it into the wrong orbit, and used more fuel than expected, making it impossible to reach the same orbit as the ISS. Despite the mishaps, both Boeing and NASA expect the Starliner’s second flight, scheduled for 2020, to include a crew of astronauts.

Songwriter and occasional actor Neil Innes, best known for his association with Monty Python, The Rutles, and the Bonzo Dog Doo-Dah Band, dies unexpectedly at the age of 75. The Bonzo Dog Doo-Dah Band’s hit “I’m The Urban Spaceman” brought him into the orbit of the Beatles, and he contributed a background track to their 1967 film Magical Mystery Tour. His participation in a later parody of the Beatles, the Rutles, led to TV specials and well-received albums, which counted among their fans and participants the former members of the Beatles themselves. Innes contributed material to the shortened final season of Monty Python’s Flying Circus, which made him one of only two members outside of the Python troupe to write material for the show (the other was future Hitchhiker’s Guide To The Galaxy creator Douglas Adams); his work with the Pythons continued into their feature films in the 1970s and early ’80s; he was also a cast member in the Pythons’ live performances during this period.
