Two years and 3 months after they bounced to landings at Gusev Crater and Meridiani Planum, the Mars Exploration Rovers are heading into their second, long cold Martian winter.

Get used to this view of Home Plate and Husband Hill, because Spirit will be seeing a lot of it over the next 8 months, whenever power levels permit the rover to eke a little bit of science activity out of the day.

Today is the day that New Horizons passes Mars' orbit (not that Mars is anywhere close to New Horizons right now).

As autumn falls toward winter on the southern hemisphere of the Red Planet, the Mars Exploration Rovers are on the move again. Although the twin robot field geologists are roving as quickly as possible to their next major destinations, the pace is slowing down.

Cassini planner Dave Seal gave me a newly updated list of times and dates for Cassini's ongoing tour of the Saturn system, so I went through and compared my table to his and made updates to flyby distances.

A news update from the MESSENGER mission last Friday included a news item that piqued my interest: they reported that the MESSENGER science team website is now live.

The audience was rapt as Project Manager Jun'ichiro Kawaguchi stood up to give an introduction to the Hayabusa spacecraft and described the saga of the mission to date.

LPSC: Thursday: Can bugs get from Earth to Europa?

I said earlier I was going to cover the poster sessions next, and there are some cool things that I want to write about, but I thought I'd better get to something a bit more topical a bit sooner: Europa and the other Galilean satellites, and when (if!?) we'll be exploring them again.

So after those two rover talks I skipped over to the other large room to listen to what the Cassini science teams had to say about Enceladus.

This morning at the Lunar and Planetary Science Conference began with Titan, and then later in the morning I had to choose between skipping Titan and going over to rover sessions, or staying with Titan. I elected to stay with Titan.

I just posted a very brief story about all of the press releases that have been whizzing around today about the possibility of liquid water on Enceladus.

They held the usual pre-arrival press conference this morning for Mars Reconnaissance Orbiter. This press conference typically doesn't convey any information that people who have been paying attention don't already know.

As early autumn descends on the southern hemisphere of the Red Planet, the Mars Exploration Rovers are on the move and picking up the pace as they rove toward their next major destinations.

I received quite a number of emails containing suggested names for Pluto's moons -- thanks! I just sent all the suggestions to Alan Stern; here they are for everybody's enjoyment.

I just posted today's installment of Planetary Radio, in which Mat Kaplan gets an update on New Horizons from Principal Investigator Alan Stern-- check it out!

Another thing I've been trying to catch up on is the daily imaging activities of Cassini, but that, too, has been tough because Cassini has been taking so dang many pictures!

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.
