Two Crazy Scientists

Lunar Space Elevator

We've posted before about the space elevator concept — an elevator going from the surface of the Earth into orbit.

It's not possible to build one with current technology. But what about a lunar space elevator? That's an elevator that would go from the surface of the moon into lunar orbit.

Spacecraft systems engineer Charles Radley argues that "A Lunar Space Elevator [LSE] can be built today from existing commercial polymers; manufactured, launched and deployed for less than $2B."

I'm guessing that dollar amount would need to be multiplied by about 100 to be closer to the actual amount.

Terraforming Venus

If humans are ever going to colonize another planet in the Solar System, the obvious choice would be Mars. But a vocal minority has long made the case for Venus. They argue that Venus has one huge advantage over Mars — it has almost the same gravity as Earth.

However, there's the problem of its scalding-hot temperature. Back in the early 1980s, French scientist Christian Marchal proposed a way to cool Venus by creating a giant cloud of dust between it and the sun.

Cooling Venus in this way might be doable, but critics have noted that, even if you succeeded in cooling it, Venus has no water, and you need water to get rid of the carbon in its atmosphere.

Marchal's supporters have subsequently expanded his idea by proposing that we could first hydrate Venus by bombarding it with hundreds of icy asteroids. Of course, doing this would significantly increase the difficulty and cost of the whole terraforming project.

Basically, none of us will ever live to see any of this happen.

Are we swallowing other universes?

An unusual cosmological hypothesis was recently published in the Journal of Cosmology and Astroparticle Physics. At least, it's an idea I haven't heard before.

It suggests that our universe has been swallowing "baby universes," and that this eating habit is the cause of the observed accelerating rate of expansion of our universe.



The article, authored by researchers from the Niels Bohr Institute and the Tokyo Institute of Technology, quickly veers off into mathematics that's incomprehensible to me. But I can extract a few interesting ideas. For instance, what if the initial "Big Bang" of our universe was caused by us (when we were still a baby universe) being swallowed by a larger universe?

the fact that the universe has expanded from, say, a Planckian size to 10−5m in a very short time, invites the suggestion that this expansion was caused by a collision with a larger universe, i.e. that it was really our Universe which was absorbed in another "parent" universe.

And what would happen if, now that we're an adult universe, we collided with another adult universe? The researchers don't answer this question, but I'm guessing the outcome wouldn't be good.

While a continuous absorption of microscopic baby universes probably can be accommodated in a non-disruptive way in our Universe, it is less clear what happens if the "baby" universe is not small, since we have not suggested an actual mechanism for such absorption.

The Kendall Paracone

In the early years of the American space program there was a lot of concern about how to get stranded astronauts safely back to Earth. One idea was the "Kendall Paracone," proposed by Robert Kendall of McDonnell Douglass.

Kendall imagined astronauts dropping from space back to earth inside of a giant, gas-inflatable shuttlecock. The shape of the shuttlecock would ensure that it always remained nose down, preventing the device from tipping over and roasting the astronaut during re-entry. It also required no parachute. It would simply plunge all the way to the ground, slowing down naturally from air resistance just as badminton shuttlecocks do. Shock absorbers in the nose would dampen the final impact.

Kendall thought his paracone system could also stop helicopters from crashing:

The One-Way Mission to the Moon

1962: Fearing that the Soviets were going to beat the United States to the moon, two engineers from Bell Aerosystems Company, John Cord and Leonard Seale, proposed a way to make sure America got there first. Their idea was to send an astronaut on a one-way mission to the moon. After all, it's a lot easier to send a man to the moon if you don't have to worry about bringing him back.

They presented their idea at the meeting of the Institute of Aeronautical Sciences in Los Angeles and also published it in the Dec 1962 issue of Aerospace Engineering.

Their plan was for NASA to first land a series of unmanned cargo vehicles on the moon that would contain all the necessities for a lunar base. An astronaut would then make the journey to the moon and, after landing, assemble the base. Every month NASA would send a new cargo vehicle to resupply the astronaut with essentials — food, water, and oxygen. This would continue until NASA figured out a way to bring him back.

NASA, perhaps sensing that the public would perceive a one-way mission as an admission of defeat rather than a sign of victory, ignored the proposal.

Base for a one-way lunar mission



Although NASA ignored Cord and Seale's plan, it caught the attention of science-fiction writer Hank Searls, serving as the inspiration for his 1964 novel, The Pilgrim Project. Hollywood developed Searls' book into a 1968 movie, Countdown, directed by Robert Altman and starring James Caan and Robert Duvall.

In both the book and movie, NASA succeeds in landing an astronaut on the moon. The astronaut then discovers that the Soviets got there first — but all died.

Bishop in Space

Nov 1957: Lord Alastair Graham offered a solution for declining church attendance. Launch a bishop into space inside a sputnik.

For context, the Soviets had just a few days before (Nov 3, 1957) launched Sputnik 2 which carried the first living creature into space, a small dog named Laika. Graham's remark was evidently a reference to this.

However, while the Soviets had succeeded in getting Laika into space, they had made no plans for getting her back alive. It was a one-way trip. It's not clear that Graham realized this, but it definitely puts a different spin on his suggestion.
