This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

Today hurricane Sandy is a major threat to life and property across the west coast of the northern Atlantic ocean. I just want to give thanks in advance to all the people who have devoted their careers to making sure that Americans have sufficient warning of devastating, unstoppable weather events like this one.

Well, that was awesome. The NPP Earth observation satellite launched successfully an hour or so ago, and I was with a chilled but thrilled crowd of a few hundred people to watch it at Vandenberg Air Force Base.

I'm (hopefully) headed to the launch of a Delta II (the last currently scheduled Delta II!) at Vandenberg Air Force Base, as one of only 20 people selected to participate out of more than 600 who registered.

It should give you a feeling of déjà vu: a defunct satellite's orbit is decaying, and because that orbit is circular it's going to be impossible to predict where and when along its ground track it's going to happen.

Data from Earth observing satellites Aura and CALIPSO have shown record losses of seasonal ozone in the Arctic.

The world watched on Friday as the derelict spacecraft named UARS made its final few orbits around Earth. And then we waited for final word of its reentry location. And waited. And waited.

Unless you've been living under a rock you've probably heard that a very large Earth-orbiting satellite is going to be reentering Earth's atmosphere soon, and there's a small but nonzero chance of debris coming down where somebody might actually find it.

Good news from Russia today: after 20 years of development they have finally launched their RadioAstron satellite (the official name is Spektr-R) into a high elliptical orbit around Earth.

I wrote the following blog entry about an image from Japan's Daichi Earth-observing orbiter last week as one to keep in my back pocket for a day when I was too busy to write, not anticipating that there'd soon be a more pressing reason to write about Daichi. On April 21, after just over five years of orbital operations, Daichi unexpectedly fell silent, and is probably lost forever.

Another painful loss to NASA's mission to study Earth from space: Today a Taurus XL rocket failed to lift the Glory satellite into Earth orbit when its clam-shell nosecone refused to open, forcing the rocket and its payload into the southern Pacific Ocean.

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

In our continuing saga of the Orbiting Carbon Observatory (OCO), the scene now switches from Copenhagen to Washington, D.C.

Climate change and Copenhagen are dominating the world news this week, as politicians, diplomats, scientists, and protesters gathered in the Danish city for the 2009 meeting for the U.N. Framework Convention on Climate Change.

...but this one is much closer to home than Katrina and Rita were.
