How and Why We Must Colonize Mars
The human exploration of Mars is not a task for some future generation. It is a task for ours, says aerospace engineer Robert Zubrin. In his new book, he details a feasible plan.
What's the Latest Development?
Fifteen years ago, aerospace engineer Robert Zubrin published The Case for Mars, calling for resolve among the aerospace community to put humans on the Red Planet. Now he has updated the book to reflect recent scientific achievements: "Today we know exactly what to do. As to cost, SpaceX company president Elon Musk testified directly to the panel that he would be willing to develop a 100 tonne to orbit class H.L.V. (heavy lift launch vehicle) for a fixed-price contract of $2.5 billion. This claim is very credible, since SpaceX recently developed and flew a 10 tonne to orbit medium lifter for a total program cost of $300 million."
What's the Big Idea?
Why is a mission to Mars so vital in the first place? Wasn't the race to the moon, after all, simply a product of Cold War power games? "There are real and vital reasons why we should venture to Mars," says Zubrin. "It is the key to unlocking the secret of life in the universe. It is the challenge to adventure that will inspire millions of young people to enter science and engineering, and whose acceptance will reaffirm the nature of our society as a nation of pioneers. It is the door to an open future, a new frontier on a new world, a planet that can be settled and the beginning of humanity's career as a spacefaring species."
Giving our solar system a "slap in the face"
- A stream of galactic debris is hurtling at us, pulling dark matter along with it
- It's traveling so quickly it's been described as a hurricane of dark matter
- Scientists are excited to set their particle detectors at the onslffaught
We know the dangers of too little sleep. Now for the other side of the story.
- Western University researchers found that sleeping over eight hours per night results in cognitive decline.
- Oversleepers suffer similar difficulties on certain cognitive tests as those who sleep under seven hours.
- Not all the news is bad: One night of oversleeping results in a cognitive boost.
Firefighters in California are still struggling to contain several wildfires nearly one week after they broke out.
- Hundreds of people are still missing after three wildfires spread across Northern and Southern California last week.
- 48 of the 50 deaths occurred after the Camp Fire blazed through the town of Paradise, north of Sacramento.
- On Tuesday night, a fourth wildfire broke out, though it's mostly contained.
