Space Travel: The Past and the Future What does a man do for an encore after walking on the moon? That's the question Buzz Aldrin faced after eight days on Apollo 11, including the first moon landing 40 years ago today. It's one of the subjects addressed in his new book, Magnificent Desolation : The Long Journey Home from the Moon.
Space Travel: The Past and the Future Forty years ago today, humans accomplished a goal as old as the species when two men walked on the Moon . We talk with Moonwalker Number Two about the Moon itself and the depression and alcoholism he faced on returning to Earth. Buzz Aldrin is among those who say the Moon itself is a dead end, but that humans could get to Mars before 2050. He insists that we should. Others point out that we've been there for five years, with robots, which make more precise observations and never need to come home.
Truth and Lies in Trumpland Donald Trump is using mis-information like no President has before him. It's an unprecedented challenge to the news media, and a potential threat to democracy. We hear how the "leader of all the people" is dividing Americans and confusing the rest of the world.
Trump's ethical conflicts pile up as transparency diminishes President Trump's refusal to reveal his income tax returns is just one example of a lack of transparency that could be hiding conflicts of interest. Other conflicts are already obvious from his appointments. And he's being sued for using his job to increase his profits.
Will the march for science politicize objective research? Protesters are gathering all over the country for tomorrow's Earth Day March for Science. Since President Trump has proposed massive cuts in basic scientific research, will the movement be perceived as partisan politics — whether scientists themselves like it or not?
