Deep Impact encounter minus 3 days

Emily Lakdawalla • July 01, 2005

OK, I'm in...I arrived at an unusually empty Jet Propulsion Laboratory this morning in advance of the first Deep Impact encounter press conference.

The Mystery of Cosmos 1

Emily Lakdawalla • July 01, 2005

I know I've probably disappointed a few people by not having had anything much to say about Cosmos 1 for a while. It's because, well, we haven't had anything much to say.

Changes to the Deep Impact encounter timeline

Emily Lakdawalla • June 30, 2005

A reader has pointed out that JPL has changed their online press kit for Deep Impact, which was my primary source material for the encounter timeline.

News: All of Earth's Eyes Are on Tempel 1 as Deep Impact Zeroes In on Comet...

Emily Lakdawalla • June 29, 2005

With four days remaining until Deep Impact crashes into comet Tempel 1, the comet is looming larger and larger in the public view.

Emily Lakdawalla • June 28, 2005

News: Dark Spot Near the South Pole: A Candidate Lake on Titan?

Emily Lakdawalla • June 28, 2005

Emily Lakdawalla • June 28, 2005

Less than a week remains before the Deep Impact mission is set to meet its fate at Tempel 1. A mission like this has been a dream for planetary scientists for a long time.

A couple of pics from Cassini at periapsis

Emily Lakdawalla • June 27, 2005

Cassini's been in orbit around Saturn for almost exactly a year now, and the mission seems pretty much to have dropped off of the public radar screen. But there's still three years to go on the primary mission, and lots left to do, and I for one am not at all bored.

The Story of Cosmos 1 is Not Over: A Personal Report

Louis D. Friedman • June 25, 2005
