If it has always been your fantasy to send your physical likeness out into the cosmos, now is your time! To commemorate the final two Shuttle missions, NASA has created a bonkers "Face in Space" initiative, which allows you to upload a picture of yourself to send to the International Space Station. What this actually entails, I imagine, is a burned data DVD in an astronaut's backpack -- nominal space travel if I've ever heard of it.
It's fun, and my face is already destined to launch on September 16th on STS-133; but, seriously, what is this about? Rousing public interest in the space…
eklemetti | June 3, 2010The NASA Earth Observatory has been dazzling us with images from the Eyjafjallajökull eruption for months - but they have been dazzling us with volcanoes images for years! Here are two more images for those of you who love seeing volcanoes from above:
Cleveland, Alaska
As I mentioned earlier this week, Cleveland volcano likely had a small eruption over the weekend producing a small ash cloud. Cleveland is already known as an extremely picturesque volcano, both from the ground for its highly conical shape - a textbook andesitic stratocone - and from space. This new June 1 image is from almost…
cevans | June 1, 2010As NASA's Space Shuttle program winds down -- Endeavour's final mission is slated for later this year, then that's it -- let us take a moment and remember the Shuttles. Sure, they had a tendency to explode into balls of fire. Sure, they were expensive, risky, and besieged by problems. But now is not the time for criticism: 25 years of American engineering, 132 missions, and over 20,000 orbits of this planet are nothing to shake a stick at. It is in this spirit of recognition that Universe presents a very subjective chronology of the Shuttle's greatest moments. Onward!

This video is simply stunning and the photography is masterful. In this video, we are looking at time-lapse photographs by photographers Scott Andrews, Stan Jirman and Philip Scott Andrews, who decided to demonstrate the process of launching a shuttle in a new and innovative way. Using time-lapse photography, they turned the 6 week process of prepping a shuttle into this gorgeous four…

The latest from Eyjafjallajökull has the volcano continuing to puff away - producing intermittent airspace closures over Europe. The Icelandic Met Office reports a ~7 km (21,000 foot) ash plume, but they note that the explosivity of the eruption seems to have waned some since a maximum on May 13. Right now, the IMO estimates the eruption rate at ~200 tonnes/second. Lets put that in a little perspective - a Ford F-150 pickup weighs about 2 tonnes, so the volcano is…
catdynamics | May 5, 2010The verdict is out, the 2010 Senior Review Committee recommendation on the NASA Astrophysics old active missions; who will keep going, and who is recommended to get the chop.
It is an interesting list, with some interesting recommendations.
And the winners are...:
1. Planck - level funding for 30 months, per request, consider 42 month extension later
2. Chandra - extend to 2012 and beyond, restore and augment funding, consider automated operation, concern about spacecraft degradation
3. Warm Spitzer - surprise winner! recommend $7M augmentation for 2012 and 2013, note spacecraft ends…
catdynamics | April 29, 2010NASA loses a balloon in the outback
The Nuclear Compton Telescope (PI Boggs at UCB's SSL), a soft γ-ray telescope designed for balloon launch, observations in the stratosphere, and recovery, crashed because of a wind gust during an attempted launch in Australia earlier today.

NCT is an wide field imaging telescope with polarization capability.
Science goals were galactic nuclear emission lines for studies of nuclear synthesis in supernovae, and γ-ray polarization studies.It flew last year out of the SFBF in New Mexico - guess they were going after southern sources…
eklemetti | April 12, 2010Lots to do!
Tourists flock to the Eyjafjallajökull-Fimmvörduháls in Iceland.
The media does love the term "supervolcano", and a number of Eruptions readers sent me a link to the article on the dreaded submarine "supervolcanoes". I would delve into this article from Live Science, but it sadly again does a dreadful job with a lot of this - remember, "supervolcano" is a made-up word by the BBC with no strict definition, so trying to say there are a dozen supervolcanoes worldwide is just silly. And why does it take multiple paragraphs and multiple mentions of "scientists" before they get a…
eklemetti | April 8, 2010Idunn Mons on Venus with recent emissivity data from the Venus Express overlaid on the topography, suggesting recent lava flows.
NASA released images today that suggest that the surface of Venus has experienced some relatively recent volcanic events (geologically speaking). By examining the surface in infrared, the Venus Express, launched by the European Space Agency (ESA) has found that three spots on the surface exhibit signs of recent volcanism. The long-and-short of the research lead by Dr. Sue Smrekar of JPL is that a number of Venutian lava flows (shown above on Idunn Mons) show less…
eklemetti | April 7, 2010Actually, no the volcanoes aren't from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit:
A recent image of Chaiten taken by EO-1. Image courtesy of the NASA Earth Observatory.
There is a great image of the busy Kamchatkan Peninsula, where four volcanoes are seen erupting in a single image - Kliuchevskoi, Bezymianny, Shiveluch and Karymsky. The plume from Karymsky is especially prominent as a grey streak above the white snow of the Russian winter (albeit it…
eklemetti | March 31, 2010As a volcanologist, I am partial to impressive lava flows, especially in volcanoes that erupt material that you'd think wouldn't produce big flows. For example, there are quite a few volcanoes in the Chilean Andes that erupt dacite lavas, which are relatively viscous (sticky), so you might expect it to erupt explosively. However, you can get large dacitic to rhyolitic lava flows, quite commonly, and these large flows are called coulées (a "volcanic dome flow").

Humans and garbage .. after you watch these videos, you'll ask yourself if humans can do anything -- even go into space -- without creating a huge trail of garbage? This space garbage is extremely dangerous, too. For example, 10-gram piece of debris can generate a collision force in space equal to the crash of a car traveling at 100 km per hour. Because of our trashy ways, it won't be long until space vehicles cannot leave earth because of the thickening belt of garbage circling planet.

eklemetti | March 26, 2010Alright, I'm actually in Wisconsin right now for a wedding, but this was too cool to pass up ... the folks from the NASA Earth Observatory sent me this image (Natural-color, 10m/pixel) from the Advanced Land Imager aboard EO-1 of the Eyjafjallajokull-Fimmvörduháls eruption, both taken on March 24, 2010.

You can clearly see the flow heading down the drainage to the east, slowly snaking down the snow covered area. I think the steam plume on far…
eklemetti | March 24, 2010I'm still playing catch-up after my week in the desert, so I've seen a lot of articles I've wanted to mention ... but a certain other volcano has taken up a lot of my time. However, I will attempt to make amends for that now.
By the way, would you believe Ubehebe Crater was closed? How do they close a volcano, anyway? However, I did get a great snap of a welded tuff on the road outside of Shoshone, CA.

Last November, in Florida, I had the opportunity to see my first Space Shuttle launch. For the hundreds of millions of people who don't pay more than a passing notice to the fact that human beings still go into space on a regular basis, this is a fairly banal thing. But to those who camp out all day, plan trips around Cape Canaveral launch windows, and scrupulously follow the ins and outs of NASA politics, this is the bread and butter.
Unless you score tickets to the Kennedy Space Center, which has the official ambiance and a giant countdown clock, the best place to watch a NASA Shuttle…
eklemetti | March 10, 2010Did I mention its a busy week?

Our Icelandic saga continues, with more earthquakes and more speculation/information on the parts of Eruptions readers. Keep up the discussion - I'll be fascinated to see who turns out to get closest to what actually happens, prediction-wise. The seismicity has quieted somewhat again in the last 12 hours, so we wait eagerly to see what comes next. Remember, Iceland is the land where volcanoes helped change history, so it is always fun to talk Icelandic volcanism.
The NASA Earth Observatory…
eklemetti | March 8, 2010Cleaning up some news ... busy week leading up to a field trip I am helping co-lead to Death Valley next week.
Ubehebe Crater in Death Valley, California
First off, I want to say how amazed I am at the great discussion that went on all weekend about the signs of potential activity in Iceland. It now appears that the earthquakes at Eyjafjallajökull may be waning, however the levels of seismicity have definitely bounced up and down over the last few days. However, the level and depth of the conversation is a testament to all volcanophiles out there. Nice job, folks.
For those of you into…

catdynamics | February 19, 2010NASA's SDO destroys a Sundog on launch.
Cool video.
The Solar Dynamics Observatory was launched, successfully, Feb 11th.
On the way up, the rocket crossed a high altitude layer of ice crystals - a wispy cloud - which was showing a Sundog - the rocket visibly rippled the cloud as it passed through - looks very cool.
