Mars Exploration Rovers Update: Spirit Works Winter Campaign as Opportunity Roves Adrift on way to Victoria

A.J.S. Rayl • May 31, 2006

The Mars Exploration Rovers are now well into their second Martian winter and, all things considered, both Spirit and Opportunity are faring pretty well for being, essentially, aging Baby Boomers on bitter cold, dusty alien planet some 50 million miles away from home.

With the Aurora program under way, the next European mission to Mars will be a rover named ExoMars, to be launched in 2011.

Europe goes ahead with Aurora

Emily Lakdawalla • May 24, 2006

This item is a little bit old -- I missed it when it was announced last Monday. ESA issued a press release stating that "European ministers approve the Aurora Exploration Programme and give green light for the ExoMars mission."

Cassini RADAR: Another Flyby, Another Completely Different View of Titan

Emily Lakdawalla • May 23, 2006

OK, I finally got a story written about the latest and greatest of the Cassini RADAR data based upon a conversation I had with with Ralph Lorenz late last week.

Cassini RADAR images of the surface of Titan

Emily Lakdawalla • May 19, 2006

Since the last Titan flyby on April 30, the Cassini RADAR team has been releasing quite a large number of pieces of the swath to the Web.

A play-by-play of the Cassini scare on Mayday

Emily Lakdawalla • May 10, 2006

Last week's Cassini Significant Events Report included a detailed play-by-play of the frightening morning of Mayday. I thought it was a very interesting read on how a mission deals with an "anomaly."

OPAG, Day 2: Ground-based study of the small bodies in the outer solar system

Emily Lakdawalla • May 07, 2006

After the political discussions of the morning, Mike Brown stood up to give the "highly subjective view of one ground-based astronomer," he said.

OPAG, Day 2: Update from the NASA Advisory Committee meetings this week

Emily Lakdawalla • May 07, 2006

During the first day of OPAG, the chair of the group, Fran Bagenal, was not present because she was participating in some rather important discussions taking place in Maryland.

OPAG, Day 1: Status of radioisotope power and communications support for future missions

Emily Lakdawalla • May 06, 2006

Following the mission- and science-focused presentations of the morning, there came two rather alarming presentations.

OPAG, Day 1: Uranus equinox is coming up

Emily Lakdawalla • May 06, 2006

Heidi Hammel gave a brief but spirited presentation designed to wake up the audience to the fact that Uranus is fast approaching its equinox, an event that will happen on December 7, 2007.

OPAG, Day 1: Hot-air ballooning on Titan

Emily Lakdawalla • May 06, 2006

The next presentation at OPAG was given by Ralph Lorenz and Tom Spilker on a Titan Montgolfiere Mission Study. What's a Montgolfiere, you ask?

OPAG, Day 1: Getting to Europa

Emily Lakdawalla • May 05, 2006

Next up at the Outer Planets Assessment Group meeting was an overview of the plans for future Europa missions.

OPAG, Day 1: Cassini and Juno status

Emily Lakdawalla • May 05, 2006

The Outer Planets Assessment Group opened with the status of two of the three actual outer planets missions, Cassini and Juno.

OPAG: Looking back

Emily Lakdawalla • May 05, 2006

The two-day meeting of the Outer Planets Assessment Group is over and I have 30-odd pages of notes to wrestle with.

OPAG: A brief update

Emily Lakdawalla • May 04, 2006

It's already 9:00 and I've hardly begun assimilating my 16 pages of notes, so I am going to have to just post a short summary with some highlights from today's meeting of the Outer Planets Assessment Group, or OPAG.

Too much outer planets news for me to read (much less report on)

Emily Lakdawalla • May 04, 2006

Before I get to my notes from OPAG I want to minimally acknowledge today's news, which I'll have to get to in more detail later.
