Record-breakers in the news today

US Doctor Who fans are being urged to keep the plot of Saturday's finale secret from UK viewers after DVDs of the series were sent out early by mistake.

BBC Worldwide said "a small number" of fans had been sent pre-ordered DVDs three weeks early.

The show’s current star Matt Smith, (born 28 October 1982), holds the record for Youngest Doctor Who, after filming his first scenes as the Time Lord at the age of 26.

Rolls-Royce has announced it is to sponsor the British Bloodhound SSC project to drive a car beyond 1,000mph.

The company will provide financial as well as technical support to the project, with a Rolls-Royce EJ200 jet engine now set to be used in conjunction with a custom designed hybrid rocket to propel the supersonic car.

The Bloodhound team are aiming to break the current land speed (fastest car) record of 1,227.985 km/h (763.035 mi/h) (Mach 1.020), set by Andy Green (UK) on 15 October 1997 in the Black Rock Desert, Nevada, USA, in Thrust SSC. Royal Air Force fighter pilot Andy will also be at the wheel for Bloodhound when the team attempts to set a new record on a 20km track in the Northern Cape of South Africa next year.

Canadian astronaut Chris Hadfield has recorded a fitting farewell to mark the end of his time on the International Space Station after filming himself performing a cover version of David Bowie's Space Oddity as he floats through the ship.

The video was posted on YouTube shortly before Hadfield handed over command of the space station to Russia's Pavel Vinogradov.

The first resident crew on board the International Space Station were Russia's Sergei Krikalev and Yuri Pavlovich Gidzenko, and the USA's William Shepherd, who arrived on the ISS on 2 November 2000 and stayed for 136 days.

Finally, a pair of Mahatma Ghandi's sandals look set to fetch more than £15,000 at auction, according to reports.

The well-worn flip-flops form part of a £250,000 haul of possessions belonging to the iconic Indian leader due to go under the hammer in Shropshire in the UK next week.

The largest gathering of people dressed as Gandhi was 891 and was achieved by Jain Muni Tarun Sagarji Maharaj (India) in Ahmedabad, India, on 2 October 2012.

The attempt was organised on the anniversary of the birth of Mahatma Gandhi at his residence at Sabarmati Ashram. The record attempt was followed by a procession to spread the message of peace and non-violence.
