The 741st episode of Doctor Who (the 43rd since the series’ revival) airs on BBC1. Kicking off the fourth season of the revived series, this episode brings back Catherine Tate’s character from The Runaway Bride (2006’s Christmas special episode) as the Doctor’s new companion. The season’s running theme – the return of Rose – is also introduced in this episode with a cameo appearance by Billie Piper, though fan sites have already reported her presence at location filming.

Oscar-winning actor Charlton Heston dies at the age of 84. Renowned for a string of tough-guy roles in major big-screen epics that earned him an Academy Award for best actor in 1959’s Ben-Hur, Heston appeared in other blockbusters such as El Cid and The Ten Commandments; genre fans may know him best for two SF films, Soylent Green and the 1968 smash hit Planet Of The Apes. His outspoken political views were on display as much as his acting skills, ranging from marching to Washington with Dr. Martin Luther King Jr. to serving as president of the National Rifle Association. He had also served as a past president of the Screen Actors’ Guild.

After four years orbiting the enormous ringed planet Saturn and flying past its dozens of moons, NASA’s unmanned Cassini probe still hasn’t seen it all. The four successful years thus far included releasing the European Space Agency’s Huygens probe to make the first ever landing on the large moon Titan, discovering (and flying through) water geysers over another moon, and exploring other moons that have puzzled scientists since they were first viewed up close in the early 1980s by the Voyager probes. The mission extension – called the Cassini Equinox Mission – gives Cassini an added two-year lease of life, with a $160 million price tag (the mission so far has cost both NASA and ESA a combined total of $3.3 billion).

Radio signals from the Martian surface indicating the successful landing of NASA’s unmanned Phoenix probe near the north pole of Mars. (To put this feat in perspective: the past several unmanned probes to land safely on Mars used a “bouncing airbag” approach; the last time a lander actually made it to the surface intact with braking thrusters and landing pads – and no airbags – was in 1976, when NASA’s Viking 1 and 2 landers successfully touched down on the planet.) The first stationary (i.e. non-rover) Mars lander since the Viking probes of the 1970s, Phoenix will stay in one spot to conduct three months of studies. Also like the Vikings, Phoenix has a soil-sampling arm and an on-board laboratory to help it determine the presence of water or water ice in its polar vicinity.
Comedy great Harvey Korman, known for his long run on the Carol Burnett Show and Blazing Saddles, dies at the age of 81. Along with Tim Conway, he was a staple of Burnett’s comedy sketch show, though an attempt to spin that success off into his own series ran aground in 1977. A year later, still a comedy fixture, he racked up his most infamous genre credit: appearing as multiple characters in the almost-trippy
