“We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.”

Elon Musk: “We’ll probably put a first man in space in about three years. We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.”

I believe him when he says he’ll launch his first manned mission in three years. However, I think he seriously underestimates the challenges of a mission to Mars, based on our present engineering abilities to build interplanetary spaceships.

Earth Day predictions from 1970

The predictions of disaster from the first Earth Day, 1970. I especially like this one:

β€œDemographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions. . . . By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.” Peter Gunter, professor, North Texas State University [emphasis mine]

A consensus was reached and the science was settled!

Remember this the next time some blowhard global-warming pundit tries to claim “the science is settled” today.
