Welcome to the Carnival of space week 23. We have two articles inspired by the 50th anniversary of Sputnick, then we have a mixed bag of articles on raising pigs on Mars, habitable planets, another look at the Apollo program, Nasa colorizing of space photos, the Carancas meteorite, Type 1a Supernovae, my own submission on hypersonic aircraft status, our wonderful planet Earth and there is a formula for the universe.
As the 50th anniversary of the launch of Sputnik 1 approaches, amateur astronomer and spaceflight enthusiast Stuart Atkinson has mixed feelings about what has – and hasn’t – happened in the last 50 years, and wonders if it’s time to declare the “Space Age” dead…
This post is about the 50th anniversary of the launch of Sputnik-1. I also include a link for a wav of the Sputnik beeping.
The first explorers upon Mars will probably rely on supplies previously shipped to the red planet in order to survive upon this harsh world. But in order to settle on this crimson globe, future Martians will need to import fruits, vegetables, grain, trees and pigs–yes pigs.
The story discusses recent work on planet formation and suggests habitable terrestrial worlds may form around stars that have had few or no interactions with other stars in their past. It’s something of a brake on the idea that Earth-like planets are forming in binary systems, but it also contradicts recent research that they could indeed form there. Controversy should follow.
FlyingSinger has been busy with travel but did take time to see a wonderful new documentary about the Apollo program, “In the Shadow of the Moon.” Produced by Ron Howard and in limited theatrical release, the story is told through recent interviews with ten of the astronauts who journeyed to the Moon from 1968 to 1972. Inspiring stuff!
If you could see the surface of Mars, or a spectacular nebula with your own eyes, would it look the same as the beautiful images from Hubble, or the Mars rovers? Sometimes yes, mostly no. Universe Today has this
article about the techniques astronomers use to coax the best images out of their data.
Astronomers have been working hard to document the universe’s rate of expansion as a function of time. To do this, we have to know how much light SN give off, and new research is indicating that this is going to get tricky as we look farther and farther back toward the beginning of the universe.
My own submission is an update and status of hypersonic aircraft and engine development
An episode of STAR TREK hinted that the whole Universe could be expressed in a simple equation. Max Planck created a universal system of units based on c, h and G. Use of Planck’s units leads to an amazingly simple result: “M = R = t”
This expression could tell a lot about the Universe, but may be ahead of its time.
