Wikipedia - Barbie, introduced by Mattel on 9 March 1959, is an iconic 11-inch doll modelled after the German Bild Lilli doll. Despite initial controversy over her figure, Barbie was marketed to children, becoming a symbol of financial independence with diverse careers. Over the years, Mattel expanded the Barbie line to include friends, siblings, and diverse versions, addressing criticisms of materialism and unrealistic body proportions. Barbie has inspired art and literature and remains a global brand, though not accepted in some Muslim countries. In 2023, a film directed by Greta Gerwig was released. Barbie continues to be a popular collectible, with annual sales exceeding a billion dollars.

It reached low Earth orbit but was deorbited after one orbit, reentering on its first pass over the Soviet Union. The spacecraft landed at 08:09:54 UTC and was successfully recovered. A mannequin was ejected during descent to test the ejection seat, descending separately under a parachute. The dog, Chernushka, was recovered unharmed inside the capsule.
