News and other tidbits that Chad Cloman finds interesting enough to share
Somehow I’ve never considered that diamonds could have a melting point, much less that there may be oceans of liquid diamond on Uranus and Neptune. Turns out that solid diamond floats on liquid diamond, much like ice floats on water. Melting a diamond, however, is more complicated than just raising the temperature. The linked article explains all.
This photographer’s work is being shown at the most exclusive gallery of all: the Moon. Astronaut Charles Moss Duke left a family photo on the Moon during the Apollo 16 mission in 1972.

As I grow older, I’m amazed to see the creation of technologies that I once read about in science fiction books. The Japanese government is spending $22 billion on a project to put a large solar panel array in orbit that will generate energy and beam it down to the Earth.

Interorbital Systems is selling satellite kits for the low, low price of $8000—this includes launching the satellite into a low-Earth orbit that will be maintained for a few weeks. The kit has quite a bit of pre-configured hardware and software, but you can send pretty much whatever you want as long as it meets the size and weight requirements. I’m thinking this would be a great way to make a marriage proposal.

It started out in the mid-1700s with the discovery of the five Lagrange points, relatively stable areas in a rotational system with two bodies (e.g., Earth/Moon or Earth/Sun). But the solar system, with its multitude of planets and moons, is much more complex. The forces exerted by gravity are changing all the time, sometimes stronger or weaker, sometimes in one direction then in another.
These dynamic forces can be modeled, and it’s possible to generate a low-energy flight path for a spacecraft, where it could (theoretically) use no fuel but instead be propelled through the solar system by these changing gravitational forces. In the real world, of course, some fuel is necessary, but it’s a minimal amount.
This type of spaceflight would not be suitable for human beings, as the path meanders significantly, taking much, much longer to reach a destination than a direct flight. But the interplanetary superhighway is ideal for certain types of unmanned probes. And kudos to the people who first came up with the idea—this is definitely thinking outside the box.
Thanks to Josh for the Lagrange point link.

Update: Here is some more recent information on this topic.
July 20th is the 40-year anniversary of humankind’s first walk on the Moon. To help celebrate, here are Ten Things You Didn’t Know About the Apollo 11 Moon Landing. My favorite is #7: “When Buzz Aldrin joined Armstrong on the surface, he had to make sure not to lock the Eagle’s door because there was no outer handle.”

Construction has started for Spaceport America. I believe we need to encourage commercial space travel as much as possible, or it will forever be the ultra high-priced monopoly of governments. It’s my hope that space travel will someday be as common as air travel is today.
The video in the linked article is from the International Space Station, and shows the stabilizing effect of gyroscopes. The demonstration is done in zero-gravity, and the “gyroscopes” are portable CD players.
This article is one of the more readable explanations that I’ve seen of how universes are created. It’s short and concise, yet manages to cover topics from quantum multiverses to what may exist outside of our universe.

The linked video is a bit long, but definitely worth watching. Astrophysicist Neil DeGrasse Tyson discusses the mechanics of being sucked into a black hole (spaghettification), as well as the possibility of the asteroid 99942 Apophis hitting Earth (and killing a lot of things in the process). Tyson also appeared on The Daily Show, where he covered some of the same topics.

This theory contends that the interior of the universe is simply a replication of the information on its outer surface. And since the 3-D (okay, 4-D but let’s keep this simple) interior can hold much more data than the 2-D surface, the internal information has a granularity, sort of like what happens when you expand a bitmap image. It sounds pretty bizarre, but there are mathematical and experimental results that may back it up. The “blurring” threshold is believed to be about 10-16 meters, which is measurable by existing equipment.

Back in 1961, astronaut Gus Grissom took two rolls of dimes into orbit on the Liberty Bell 7 spaceflight. Upon returning to Earth, Grissom’s capsule sank in deep ocean waters and he was forced to leave the coins behind. The capsule was retrieved in 1999, and the dimes now reside in a space museum.
