FlyingSinger brushes up his space navigation skills and prepares for his April IYA podcast with a flight from Europa to Callisto, simulated in Orbiter.
During this International Year of Astronomy we celebrate Galileo’s telescope observations 400 years ago. He did not start his career believing Earth circles the Sun, but his telescope revealed phases of Venus and moons circling Jupiter. 445 years after his birth Galileo is still an example for today’s scientist.
In honour of International year of Astronomy, and the 400th anniversary of Galileo peering through a telescope at the heavens, I’m blogging Galileo’s “Sidereal Messenger”, Galileo’s first report of his telescopic observations. Each week I’m going to blog one “chapter” of the Starry Messenger (actually, it doesn’t really have chapters, but it has self contained sections I’ll talk about. This week I start with the Introduction.
4. Scouting Life (Canada) published articles in their winter issue to help youth leaders conduct stargazing sessions. Reprints can be found at Explore the Night Sky and Make Your Stargazing Events Shine
A tremendous fireball — also called a bolide, or a very bright meteor — was seen in southern Texas on Sunday, February 15th, just before 11:00 a.m. local time. Many people have described it as very bright, small, and moving rapidly.
6. Centauri Dreams writes about “361 Civilizations in the Galaxy?”
This follows up an earlier post on recent statistical treatments of the Drake Equation, trying to figure out to a greater degree of accuracy how many technological civilizations may be out there. Nobody knows, of course, but it’s intriguing to watch the different methods being used to juggle the inputs!
12. OrbitalHub looks at the Dawn spacecraft and the Flyby of Mars.
The Dawn spacecraft is currently performing the Mars flyby phase of its mission. The purpose of the Mars flyby is to alter the trajectory of the spacecraft in order to rendezvous with its first scientific target in the main asteroid belt. The scientific objective of the Dawn mission is to answer important questions about the origin and the evolution of our solar system.
It’s part of an ongoing series of posts based on a huge 2001 paper that summarizes the results of the Mars Orbital Camera (MOC): the first high-res camera in orbit around Mars.
16. Dave Mosher of Discovery Space provides: String theory — a proposed “theory of everything” — is criticized for its lack of experiments, but scientists are could be building a case to tear that wall down.
21. 21st Century Waves looks at “North Korea’s New Space Program?”
24. This site looked at detailed studies of cement jet printing buildings on thd moon.
Super-Orion whose 400 meter diameter footprint covers about 30 foot ball fields and has the internal volume of about 10 great pyramids at Giza. The hundreds of nuclear explosive above ground tests from the 1960s could be repeated from a launch in the Pacific so that the true space age could begin with a kickstart of 120,000 Space Shuttle loads not just to low earth orbit but anywhere in the solar system. What was done for geopolitical and military posturing could be done again for the future of mankind. Becoming a true space faring civilization if we could only understand that it would actually be safer and provide huge economic and technical benefits.
in 2020 – about the same time NASA is planning to send astronauts Back To The Moon – two rockets will blast off, from different sites, each one carrying a spaceproeb bound for Jupiter. Six years later the probes would enter the Jovian system and go into orbit around its Galilean satellites, Io, Ganymede, Europa and Callisto, paying particular attention to two of those moons, namely Europa and Ganymede.
