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

"Mars Spectacular!"

Emily Lakdawalla • June 28, 2005

Apparently there is a bogus email circulating around the Web with the following text: "The Red Planet is about to be spectacular!" But Mars is not about to appear "as large as the full Moon."

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

Emily Lakdawalla • June 28, 2005

The Cassini imaging team has released an image containing a feature unlike any other that they have seen on Titan. The very dark color, curvaceous outline, and sharp edge of the feature have led them to the conclusion that it could well be the long-theorized but never-before-seen body of liquid hydrocarbons on the surface of Titan.

Heads up: the Deep Impact encounter is coming up!

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

The word failure is sticking in my craw. Certainly, we failed to achieve the objective of Cosmos 1: we did not achieve solar-sail flight. But I don’t think, with all we have done, that I can call Cosmos 1 a failure.

Piecing the Data Together

Louis D. Friedman • June 23, 2005

We’ve had a very exciting day here in Moscow. Bud Schurmeier and I met with Konstantin Pichkhadze, head of the Lavochkin Association, which built our spacecraft, Cosmos 1.

"We have a live spacecraft..."

Emily Lakdawalla • June 21, 2005

...we think.

Final Words Before Launch

Louis D. Friedman • June 21, 2005

Speaking by phone to a roomful of journalists in Pasadena less than 2 hours before the expected launch, project director Louis Friedman reiterated his confidence in the entire Cosmos 1 team.

The Launch of Cosmos 1: Live Reports

Bruce Betts • June 21, 2005

In the past twenty-four hours, the Russian space agency (RKA) has made a tentative conclusion that the Volna rocket carrying Cosmos 1 failed during the firing of the first stage. This would mean that Cosmos 1 is lost.

Cosmos 1 Solar Sail will Carry CD into Orbit

Susan Lendroth • June 16, 2005

When Cosmos 1, the first solar sail spacecraft, launches on June 21, 2005, it will carry into Earth orbit a CD containing the names of over 75,000 members of The Planetary Society and the Japan Planetary Society, along with the works of early visionaries who inspired solar sailing.

Cosmos 1: Another rehearsal...

Emily Lakdawalla • June 15, 2005

Rehearsals don't always go so well, which is the whole point of rehearsals. That was true both for us and for the Russians today, in separate simulations of mission operations.

Cosmos 1 "Mated" to Volna Rocket in Preparation for Tuesday Launch

Louis D. Friedman • June 15, 2005

The world’s first solar sail spacecraft, Cosmos 1, is now mated to its Volna launch vehicle and ready for its ride into space.

"Our works with the spacecraft are finished successfully."

Emily Lakdawalla • June 10, 2005

Here at Cosmos 1 Project Operations Pasadena -- or POP -- we are scrambling to get our mission operations plans and procedures ready for our launch, just 11 days from now.

Mars Exploration Rovers Update: Opportunity Roves Out of Sand Dune as Spirit Uncovers Clues of Past Explosions

A.J.S. Rayl • June 05, 2005

Nearly a year and a half after landing on the Red Planet, the Mars Exploration Rovers are continuing to collect important science and impress the team with their resiliency.

Worldwide Network to Track Cosmos 1

Susan Lendroth • June 02, 2005

From Moscow to the Marshall Islands and California to the Czech Republic, tracking stations around the world will receive data from Cosmos 1, the world's first solar sail spacecraft after it launches on June 21, 2005.

Emily Lakdawalla • June 02, 2005

As MESSENGER began its approach for its August 2 flyby of Earth, its cameras have snapped their first images. The images clearly show a cloudy Earth—and, to scientists' surprise, the Moon as well.
