Principia logo revealed

BBC presenter Lindsay Russel, logo designer Troy and ESA astronaut Tim Peake with the Principia mission logo.

The BBC’s Blue Peter programme asked schoolchildren to design a mission patch for Tim and received more than 3000 entries.

The winning entry is by 13-year-old Troy, who explains: “Principia refers to Isaac Newton’s principal laws of gravity and motion so I drew an apple because that is how he discovered gravity.

“Plus Tim Peake is promoting healthy eating as part of his mission and apples are healthy.” Fittingly, a stylised Space Station glints in the apple.

The Soyuz rocket taking Tim into space flies over the UK as the colours of the Union Flag run along the border.
