Tomorrow is the 20th anniversary of the launch of the Hubble Space Telescope. It's hard to believe it's been going strong for so many years.

A successful sample return for the Hayabusa mission will mean the fiery death of Mr. Hayabusa himself. The poignancy of this is not lost upon the people in Japan who are following the mission.

Here's a new lovely color composition of Titan and Dione captured by Cassini. This one was taken on April 20, 2010; a set of 15 raw images taken of the two moons just showed up on the Cassini raw images website.

JAXA has issued a notice with a little bit more detail on the timeline for Hayabusa's return to Earth.

It really looks like Hayabusa is going to make it home. Hayabusa's sample return capsule will be returning to Earth on June 13, 2010, landing in the Woomera Prohibited Area, Australia at about 14:00 UTC.

It's axiomatic that as soon as I post about pretty Cassini pictures, another set of pretty photos will appear on the raw images website.

Cassini has it almost too easy. Point at anything in the Saturn system and you're guaranteed of a shot that looks, at least, pretty.

Venus? What? Somebody still studies that planet? Yes, and in fact there's an active spacecraft there: Venus Express, the poor little sister to Mars Express.

The Cassini Saturn orbiter just completed its second very close flyby of Saturn's mid-sized iceball moon Dione, and the images from that encounter have been streaming onto the Cassini raw images website this morning.

Yesterday was the Mars Reconnaissance Orbiter HiRISE team's latest flood of archived images, 1,025 of them. I skipped forward to page 42 (what other number would I pick?) and started browsing from there.

Here's a lovely picture whose components came down from Cassini a few days ago.
