- Is This the Death of Comet ISON? Thursday, 28 November 2013, 7:25 pm
UPDATED 11/29 All along, astronomers knew that there was a real possibility that Comet ISON would not survive its passage by the sun. Now it seems like the comet may in fact be in the middle of a cata. […]
- Correction to Cassini Costs and a Good Link Wednesday, 13 November 2013, 1:07 am
In my post yesterday on the potential loss of the last years of Cassini’s extended mission at Saturn, I quoted the wrong costs for operating Cassini. The correct figure is $60-65M per year, and not. […]
- Will We Lose Cassini’s “New” Mission at Saturn to Budget Cuts? Tuesday, 12 November 2013, 8:40 am
NASA’s shrinking budgets for planetary exploration may force it to decide between continued funding for the Saturn Cassini mission and the continued funding for its Mars missions. Mars would seem. […]
- Europe Bypasses the Solar System for Its Next Large Science Missions Thursday, 7 November 2013, 1:11 am
In September I wrote about the European Space Agency’s competition to select its next two large (~€1B) science missions. While many exciting solar system concepts were included, ESA’s manageme. […]
- CubeSats to the Planets Sunday, 20 October 2013, 4:40 pm
I’ve seen the evolution of computers used as an analogy for the evolution of spacecraft. Once, all computers were massive machines (called mainframes). Then the evolution of electronics allowed. […]
- All over the map Saturday, 16 November 2013, 11:42 pm
The photometry from the Kepler Mission stopped flowing a while back, but results from the Mission will likely be arriving for decades to come. It’s interesting to look at how the mass-density diagra. […]
- 3:45 Sunday, 29 September 2013, 1:03 am
I’ve written several times, most recently last year, about the Pythagorean Three-Body Problem, which has just marked its first century in the literature (See Burrau, 1913). Assume that Newtonian Gra. […]
- Malbolge Saturday, 21 September 2013, 10:11 pm
Fall quarter at UCSC has arrived, and with it, the latest iteration of my astrophysical fluid dynamics course. This class covers the workings of bodies that are composed of gas, ranging from molecular. […]
- Central Limit Theorem Wednesday, 21 August 2013, 8:08 pm
We’re putting the finishing touches on a new research paper that deals with an old oklo.org favorite: HD 80606b. The topic is the Spitzer Telescope’s 4.5-micron photometry taken during the interva. […]
