Dreaming of Easy-to-Use Data

Some thoughts on how difficult it is to use multiple different types of data in planetary science, how easy it could be, and two free programs that are important first steps in making easy-to-use data a reality.

AGU 2010 – Days 3 and 4: Exoplanets, Impact Basins and Alteration

Now that it’s a New Year, it’s time I wrapped up my AGU 2010 recaps. This post covers Wednesday and Thursday, with lots of good stuff about super-earth exoplanets, impacts on the Moon and Mars, and lasers on Venus!

AGU 2009 – Day 1

For those not familiar with the conference, the fall meeting of the American Geophysical Union is a terrifyingly, overwhelmingly large conference. Each year, something like 16,000 geoscientists descend on San Francisco to share their work. It is also one of the major planetary science conferences, so a lot of new results are first presented here. This year, the first talks that I checked out on Monday were about radar observations …

New Google Mars

Google Earth’s latest edition was just released and guess what? It has a Mars setting! There was a way to overlay Mars data on the Earth globe in previous versions, but now that’s no longer necessary: just click a button and you’re on Mars. You can choose from a variety of global maps including topography, Viking images, Day and nighttime infrared, and visible color. It also has footprints for high …

Potential MSL Site: Holden Crater

The next landing site that we heard about was Holden Crater. Holden is a 154 km diameter crater formed early in martian history that happened to fall smack in the path of an extensive fluvial system. There was a long chain of craters connected by water-carved channels¬† and then the Holden impact occurred and interrupted that flow. It looks like Uzboi vallis, one of the channels, then breached the rim …

Potential MSL Site: South Meridiani

The south Meridiani landing site is a newcomer to the bunch. It was added earlier this summer as a replacement for the north meridiani site. The south Meridiani site is about 100 km due south of the Opportunity rover landing site and about 100 km due east of the Miyamoto site. What makes the south Meridiani site interesting is that, just south of the landing ellipse, you transition from Meridiani …

New insights into ancient water on Mars

The evidence for a warmer, wetter ancient Mars just keeps piling up! In 2 new papers, the team for the CRISM spectrometer onboard NASA’s Mars Reconnaissance Orbiter has reported new evidence for water on the surface of ancient Mars, based on the ubiquitous presence of water-bearing minerals. Universe Today has a great post up on the findings, so I won’t repeat too much of Nancy’s explanation. In brief, the CRISM …
