To Mars, and beyond: Buzz Aldrin describes vision for space exploration

Aldrin urges US cooperation for Mars mission and says plan for 'cycler' spacecraft could be tested on asteroid visit during Trump's first term and future Venus fly-by

Nasa should aim to reach an important milestone on the way to Mars during Donald Trump's presidency, astronaut Buzz Aldrin told a conference on Tuesday.

Trump spoke of being "ready to unlock the mysteries of space" in his inaugural address and last month signed a Nasa funding bill containing the most comprehensive language yet in support of Mars exploration, setting a target of 2033 for a manned mission.
