Should We Launch Mission to Mars?

Buzz Aldrin and Michael Collins have urged NASA to scrub its lunar ambitions and set its sights on Mars, the BBC reports.

Speaking at an Apollo 11 reunion of the pair and Neil Armstrong at Washington DC's National Air and Space Museum, marking the 40th anniversary of the first Moon landing, Collins said: "I worry that the current emphasis on returning to the Moon will cause us to become ensnared in a technological briar patch, needlessly delaying for decades the exploration of Mars - a much more worthwhile destination."
