You may have noticed that Comet ISON appears to have a green halo in some recent images, but in other images acquired at about the same time, it doesn’t. Thanks to the beautiful new spectrum posted earlier today by Christian Buil, it’s relatively easy to understand why.
Cosmos with Cosmos Episode 3: The Harmony of the Worlds
In which Mars changes the course of human history
We continue our analysis of Cosmos as we jump back in time to see the birth of modern science with Johannes Kepler or, as Sagan calls it, the first fusion of "imagination with observation." Welcome to Episode 3: The Harmony of the Worlds.
China's Chang'e 3 lunar soft lander and rover are proceeding toward a planned December launch. The Long March-3B rocket departed Beijing for the Xichang launch facility yesterday, and is expected to arrive November 1. Meanwhile, 190,000 contest entries have been winnowed to a list of ten possible names for the rover.
On sol 3451 Opportunity began its climb of Solander Point. This is the highest “mountain” that Opportunity has tried to climb yet.
The Planetary Society’s work beyond the United States is still not nearly as extensive as it is in the Society’s home country. But we are making some huge steps towards changing that, starting with Canada – America’s neighbor, NASA’s partner, and the home of almost eighteen hundred Planetary Society members.
The Autumn Equinox 2013 issue of The Planetary Report is hot off the presses and is in the mail.
The Martian Geologic Time Scale is a lot more complicated than the Moon's.
This book is so great. I cannot imagine how many hours of happy building went into the development of the various LEGO ships and space bases included in this book, but I wish I could have participated.
After a brief science stop at Darwin (formerly known as Waypoint 1), Curiosity has driven hundreds of meters toward Mount Sharp. Autumn has come to Curiosity's southern hemisphere location, bringing lower temperatures. That means more power is required to heat rover actuators, leaving less power for science along the drive.
The launch of ISRO's Mars Orbiter Mission has been delayed by about a week due to bad weather in the Indian Ocean. The new launch date is November 5 at 14:36 IST (09:06 UTC / 01:06 PST). Their launch opportunity stretches to November 19.
Cosmos with Cosmos Episode 2: One Voice in the Cosmic Fugue
In which we are connected to all living things
In episode 2 we switch from cosmos to microcosm and discover how we are connected to all living things. Is Sagan too authoritative in this episode? Plus, a major error in one of the stories.
It’s been a long time since anyone paid Uranus a visit. The Uranus system is, however, fascinating, as evidenced by the wealth of topics covered by the diverse group of planetary scientists who gathered to discuss it last week at the Paris Observatory.
In which I summarize Joe Veverka's Kuiper Prize talk at the Division for Planetary Sciences meeting: "Small is NOT Dull: Unravelling the Complexity of Surface Processes on Asteroids, Comets and Small Satellites."
I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.
