The "Water on the Moon" Hoopla, Part 2: The murkier part of the story

Emily Lakdawalla • September 25, 2009

How much water is there on the Moon, and is it in a form that human explorers could use? This part of the story has many more questions and many fewer definite conclusions.

The "Water on the Moon" Hoopla, Part 1: There's water on the Moon!

Emily Lakdawalla • September 25, 2009

For a couple of weeks now, I've been hearing rumors about an upcoming announcement concerning Chandrayaan-1 Moon Mineralogy Mapper ("M3") discovery of "lots of" water on the Moon.

Exciting Times Ahead: 2010 Will Sizzle, and 2011 Will Really Cook!

Alan Stern • May 18, 2009

Today, I'm kicking the week off with a look at the unusually intense confluence of far flung planetary exploration that's just around the corner, starting the middle of next year.

A lack of information for a Deep Impact update

Emily Lakdawalla • August 24, 2005

I had very much hoped to be able to post an update about the Deep Impact mission this week, but it looks like my various sources are keeping very very quiet (or maybe they are just tired of me pestering them :)

A Deep Impact update

Deep Impact Data Surprises Scientists

A.J.S. Rayl • July 12, 2005

When Deep Impact crashed into the nucleus of Tempel 1 at 23,000 miles per hour on July 4, it sent a huge, bright cloud of stuff upward and outward from the comet, providing a spectacular image that is already assured a place in the space history books, and may well be seared into the brains of all those who watched the event.

Another gorgeous Deep Impact image

The team has just released a really pretty high-resolution view of Tempel 1 just 67 seconds after the impact.

Reflecting on Deep Impact

Emily Lakdawalla • July 05, 2005

So yesterday, after covering the Deep Impact press conference at JPL and recording for Planetary Radio, my husband and I drove to his parents' house for an Independence Day barbeque. When I explained the nature of the Deep Impact mission my mother-in-law exclaimed, "What! What gives you the right to go around smashing up a comet that was minding its own business?"

Rockin' to Bill Haley and his Comets

Emily Lakdawalla • July 05, 2005

There was a stage set up on the steps of the administration building, and the quad in front of it was filled with JPLers of all ages and descriptions. Rick Grammier and Don Yeomans introduced the band -- five guys, all members of the band since 1953 or earlier, still rockin' and rollin'.

News: Deep Impact Delivers the Science; Years of Work Ahead for Science Team

Emily Lakdawalla • July 04, 2005

"Our cratering experiment went very very well," reported impact scientist Peter Schultz in what may have been the understatement of the weekend. A first look at early science results from the mission suggest that while some events unfolded according to scientists' predictions, Tempel 1 provided many enticing surprises as well.

Notes from the morning-after press conference

Emily Lakdawalla • July 04, 2005

Here in Von Karman auditorium at JPL, as they get ready for the press conference, they are playing "Rock Around the Clock," by Bill Haley and His Comets. Very appropriate! The press panel is mostly familiar: Andy Danztler, Rick Grammier, Shyam Bhaskaran, Mike A'Hearn, and Pete Schultz.

Views of Tempel 1

Emily Lakdawalla • July 04, 2005

It looks like the European Space Agency was busy overnight -- lots of great Earth- and space- based images of the impact have been appearing on various websites.

Deep Impact Comet Crash Produces Great Big Comet Flash

The panel consists of: Andy Danztler, Solar System Division Director at NASA HQ; Rick Grammier, Deep Impact Project Manager, JPL; Jennifer Rocca, Deep Impact Systems Engineer, JPL; and Mike A'Hearn, Principal Investigator, University of Maryland.

The Deep Impactor is safely on its way!

Emily Lakdawalla • July 03, 2005

I woke this morning to find a press release in my Inbox that said: "One hundred and seventy-one days into its 172-day journey to comet Tempel 1, NASA's Deep Impact spacecraft successfully released its impactor at 11:07 p.m. Saturday, Pacific Daylight Time," or 06:07 UTC.

Deep Impact On Course for Comet Crash; Mission Is Already Producing Science Returns

Emily Lakdawalla • July 01, 2005

NASA's Deep Impact spacecraft is set for its date with Comet Tempel 1. "We are going to hit a bullet with another bullet while watching from a third bullet," said Charles Elachi, the head of JPL.
