Cassini and the Enceladus Plume

I know it sounds like the title from a children’s book about a young lad named Cassini who has to run through the magical hair-gardens of the kingdom of Enceladus, but it’s way cooler than that.

On November 2, the Cassini spacecraft successfully flew through that really cool¬†plume of what is currently thought to be “water vapor, sodium, and organic materials” from previous flybys. While it was doing so, it was relaying information back to the NASA scientists involved in the project who are now knee deep in new information about this incredibly interesting moon of Saturn. They took some distant pictures capturing some incredible photos of the planet from afar, but also flew about 100 kilometers above the surface, all the while snapping pictures and analyzing the surface of the planet with VIMS, their Visual and Infrared Mapping Spectrometer. There’s great information up giving a higher level view of the findings at ScienceDaily, and a really great description with more detail on NASA’s page written by Bonnie J. Buratti, one of the scientists involved in interpreting the data.

NASA Replicator: Not quite Star Trek, but Scotty would be proud

replicatorMy dad first introduced me to the world of Star Trek, and opened my mind to a world of communicators, dark matter, and replicators. These days we all own mobile devices so advanced they would make a Cardassian jealous, the existence of dark matter has been proven many times over, and now at long last it looks like the replicator is about to make its debut.

Hubble’s Upgraded Lens Blows Minds!

Butterfly Nebula

butterfly Nebula

Since I’m currently posting from work, i have little time to wax eloquent, but Hubble is back in business after going through the most complicated and successful spacewalk repair in history. The telescope has been taking a few test images just to get its bearings and …

DAMN!

The image of the Butterfly Nebula alone is worth the billion dollar expense :)

More Mars Images

NASA has released thousands of new images of Mars, including the one pictured to the left. This one shows is entitled Gullies at the Edge of Hale Crater, Mars. They were taken by the HiRISE (High Resolution Imaging Science Experiment) camera aboard the MRO (Mars Reconnaissance Orbiter).

If I’m reading the site correctly, then there are 1512 images of the surface of the Red Planet.

Astronauts Battle Rubble for Hubble

The Hubble Telescope has been orbiting our planet and delivering mind-boggling images from deep space for 19 years. During that time it has only been repaired once: right after it was first launched. Like all old machinery Hubble is due for a tune-up and an upgrade. Given that the total cost of the repairs is estimated at 1.1 billion dollars, many have argued the necessity of the mission in these economic hard times. Thankfully NASA has obtained funding and Space Shuttle Atlantis launched a few days ago with a payload of new instrumentation and a full crew. This new instrumentation will allow scientists to probe deeper into the Hubble Ultra Deep Field .. looking back further than 13 Billion years in time … perhaps even looking back 14 Billion years to within a few million years of the birth of our universe.

When the shuttle first opened its payload doors yesterday, the new Canadarm was depolyed to look for any damage that may have occured during the launch. The crew found a few minor scrapes and bruises and for a while there was some trepidation over a successful landing, but further investigation seems to have put their minds at ease.

The real issue will be the thousands of pieces of space junk littering the area. Atlantis is situated in one of the most junk-populated areas in earths orbit … our planets own orbital junk heap. These projectiles can travel at up to 20,000 mph, so even a small pea-sized projectiles can cause life-threatening damage. The crew is at great risk when performing repairs and upgrades in open space.

I’ll be grateful to see them land safely and excited to see the images and data start flooding in from this legendary instrument.
