A Matter Of Perspective


Imagine with me if you will, you are orbiting the Moon in spaceship Boba at about 150 miles distant from the Lunar surface traveling 2,000 mph on your way to Tycho City (Tycho is the crater at the top of the image with a central peak), and you look out your window and snap an image, the above image is what you'd see, no it's not taken by a lunar probe or any of the Apollo missions, it is one of my highly magnified lunar images, I figured out how to change the perspective of an image in photo shop so that it looks like your flying over the Lunar landscape as opposed to looking at it through a telescope. I was going through some of the images taken by lunar probes and the Apollo missions in Virtual Moon Atlas and thought it would be cool if I could get the same effect on some of my images, so after many hours of fooling around with the free transform edit tool in photo shop I was able to come up with a totally different viewpoint hence the above image. You may ask why would I spend all that time doing that, I ask why not, it looks cool, takes me away even further then I already am from our Earthly constraints to a place where you can imagine the impossible, besides a had a few hours to kill the other night.

The Shuttle Discovery arrived home safely yesterday at 1:01 pm. EST. after a successful and complex mission. This is space exploration at its finest, from the ability and ingenuity of being able to develop things like cufflinks to repair one of the International Space Station's solar arrays to preparing the Space Station for further space exploration with the installation of the Harmony module, this is why I blog so much about the Shuttle program, these people are making things happen up there so we can reach for the Moon and beyond, they are our modern day Columbuses!



Okay this is just too cool. Japan's Lunar orbiter Kaguya has just sent back high definition Images of the moon along with a HD Movie. The movie has 2 sequences, one of the Lunar polar area as in the above image, and another sequence of the Oceanus Procellarum region. The images were shot about 100km from the Lunar surface, how exciting is this?!




NASA's Dryden Flight Research Center's Fabrication Plant released a picture of a mock up of the Orion crew module. It is America's first new manned spacecraft since the shuttle was developed 30 years ago. The Orion is part of the Constellation Program which will return us to the Moon by 2020.

Shuttle's Coming Home

Astronauts on the Shuttle Discovery have completed repairs on the solar array successfully using the home made cufflinks and are heading home. After the Shuttle Discovery undocked from the ISS they performed the 360 loop around the space station to take one final look to ensure nothing is about to fall off the station, it also allows the station's crew to take final images of the shuttles heat shield to analyze later for damage, which is now standard practice ever since the 2003 Columbia disaster. As the astronauts were leaving the ISS yesterday while closing the hatches Clayton Anderson noticed a ding on one of the shuttle's thick windows, NASA doesn't anticipate any complications from this, apparently the window was struck by a micrometeorite. Below is a picture of one of the cufflinks used to repair the solar array. The shuttle will be landing at Kennedy Space Center,Fla. 1 pm.EST Wednesday.




There are a couple of good meteor showers coming up in the next couple months to watch out for. Late evening on November 17th. through the morning hours of November 18th. sees the return of the Leonids meteor shower. The source of the shower is the parent comet Tempel-Tuttle discovered independently by William Temple in December 1865 and Horace Tuttle in January 1866. Look for the radiant, the place where the meteors seem to start from low in the NE. sky around 11:30 pm November 17th. that's where and when the constellation Leo rises. Leo will continue to rise until early morning bringing with it 20-30 meteors an hour.


The second major shower, the Geminids will occur December 14th. but you'll be able to catch them between December 7-16 with peak activity December 14th. The Geminids are the most reliable of all the showers with up to 120 meteors per hour. Look for the constellation Gemini, the radiant of the shower to rise in the NE. sky around 8pm. and will of course continue to rise and bring with it many meteors from dusk to dawn. Find yourself a comfortable spot or even a chair and get comfy, make sure you're warm, here in Saskatchewan 20c below is normal for December. If you find yourself relaxing too much to a stage where you're dozing off and seeing visions of Obi Wan Kenobi your probably getting dead, snap out of it man and get inside and warm up. Mars as a bonus will also be in the constellation Gemini. Every 26 months Mars and Earth get the closest they can be in their respective orbits around the Sun. On December 18th. at 6:46 pm.EST. Mars will be within 55 million miles of the Earth, I can't stress enough, get some binoculars, it'll be worth it


The best viewing of celestial objects is happening right now. I was up at 5am. Saturday morning, it's hard to put into words, the sky was full of gems. It's like all the players showed up for the performance of the century and I was the only one invited. Venus starts off the show a bright white gem low in the east; Saturn next, a bright yellow ball a little higher in the south east; a little further west was the Moon followed by Mars high in the south; west of Mars was the open star cluster the Pleiades and then just north west of the Pleiades is Comet Holmes. These are all naked eye candies, don't need a scope to view this stuff people, it was a busy quite, if that is even a term, it was remarkable!


I am going to leave you with a compilation of my best Comet Holmes images I took from October 25th to November 2nd. all at 200x. I put them all together in windows crappy Vista operating system's "Movie Maker", but that wouldn't upload properly, duh, Vista, so I uploaded to You Tube and embedded it to my blog. WARNING!!!, if you have an irrational fear of a comet crashing into the Earth destroying life as we know it, don't push the play button! Also just a note to let you all know I will be posting every Monday and Thursday nights from now on.

Most Dangerous And Difficult Spacewalk


Saturday November 3rd. astronauts on the shuttle Discovery mission STS 120 will be making what they are calling the most difficult and dangerous spacewalk ever attempted. During the mission's third spacewalk which consisted of moving a large solar array panel on the " P6 truss" which by the way weighs 35,000 lbs, as they were extending the array astronauts noticed a couple rips in one of the panels. They immediately stopped the extending process fearing more damage and took pics to send home. The array is 80% deployed, is still generating 97% of its full capacity but NASA scientists are saying it is structurally unstable and must be repaired.





The plan is to "button-up" the two rips with "cuff links" which the astronauts crafted with supplies found in the station's lab. Astronaut Scott Parazynski will be attached to an extension, attached to the Canadarm (above picture), take the one hour ride out to the problem area and effect repairs. What makes this mission more difficult is that as Scott Parazynski is repairing the array there is a possibility of electrical shock as the panel is supplying 110 volts, generating 13.4 hp. and there is no off switch, once the array is deployed it's on.


Comet Holmes continues to get bigger! It's like I found a new toy, every night I look forward to getting out and viewing the comet. What is really unusual about this whole situation is that I have had clear skies almost every night since the comet increased a million times in brightness. If you haven't yet, get out and take a look, very easy to spot now, as it gets dark look to the NE half way up from the horizon, you will see a fuzzy yellowish ball, that's the comet. I'd like to have you all over to show you what it looks like through a telescope, it is too cool, if you can get or borrow someones binoculars do it, who knows how long it will last, maybe only a couple more weeks, enjoy it while you can. Below is the first image I took last Wednesday October 25th. at 200x, below that is my most current one taken October 31st. at just 74x. Notice the green halo around the comet on my most current image, that is fluorescing gases mostly carbon monoxide, one of the byproducts of the explosion.

Comet 17P/Holmes is Getting Bigger!

Comet Holmes October 29th. 2007 ,200x

I took the above images over a five day span to show how much it has grown in such a short amount of time, all at the same time every night and at the same magnification.

The Blogs and Message Boards are all abuzz with all kinds of theories and ideas about the expansion of this odd comet. One theory I never thought of is that someone had mentioned that this expansion and the Shuttle launch occurred around the same time and that the whereabouts of Bruce Willis at this time is unknown, I laughed til I stopped at that one.


Comet Holmes is from what they call "Jupiter's family of comets". It is a short period comet and completes one orbit around Jupiter and the Sun every 7 years. Right now it is approximately 246 million kms. distant from the Earth, it had its closest approach to the Sun last May and will be its closest to Earth around November 7th. when it will be 243 million kms. distant, so no worries about it crashing into us, one of the theories why there is no tail is that we can't see it cause it's heading straight for us.


Scientists don't really know why all of a sudden it got a million times brighter but they figured it happened once before back in 1892 allowing British astronomer Edwin Holmes to discover it. A comet has a honeycomb framework of solid particles enclosed in ice, one theory is that some of the comet's ice sublimated when it was closer to the Sun exposing a portion of it's core and just last week becoming unstable enough so that it's gravitational field could no longer hold it together and it broke up releasing massive amounts of dust, (which would account for the yellow/orange color), as well as releasing gases such as carbon monoxide.





Where is this comet and how can you find it? The above picture shows you where to look. Go outside just as it is getting dark, look to the North East about half way up from the horizon, you will see a bright yellow star like object, that would be Holmes, it is just down and to the left of Mirfak in the constellation Perseus. No one is really quite sure how long it will be visible, could be 3 weeks or longer, right now it is still in the growing stage, may even grow a tail who knows.

I'll leave you with a clip that a fellow amateur astronomer/astrophotography friend Tenho Tuomi made up of my images to give you a better idea the growth of this fascinating comet. Check out his website he lives outside of town and has some great astro images he has taken throughout the years. Just click on the image below and away you go.

Comet Holmes


Edwin Holmes was doing some observing of the Andromeda Galaxy and discovered comet Holmes way back in 1892, you know the story, you find it, it gets named after you. Just last Tuesday it started getting very bright, like about 1 million times brighter! Scientists figure the only way it could have gotten that bright that fast is through a major out gassing and releasing major particles from its nucleus. I took the image above last night, it is at 400x you can see it's pretty weird shaped for a comet, round and all, and the comet nucleus a star like appearance in the middle, you can make out it's tail pointing away from the Sun. It will be visible to the naked eye for at least the next week. You can spot it in the NE sky after it gets dark. It is just to the west of the star Mirfak in the constellation Perseus. It is quite easy to find, looks like an orange yellow star. Check out Rick's Deep Sky Blog, he has an interesting post on the comet as well.



I took a pic of my set up last night. I had just taken some pics of the comet and was now taking some highly magnified images of Moon craters, in fact if you look at my sucky VISTA operated computer in the pod you can see the Moon being imaged. A real cool thing that happened to me, I submitted one of my photos of the comet to Sky and Telescope magazine's website, and it got chosen to be added to their photo section, not only in one of their regular categories, which is an honor in itself, but as an Editors Choice. Who knows for how long it will be there because they get billions of pictures everyday, and the Editors choice is for all the categories. I'm sure it will be around for a while in the Comet Holmes area.



So far so good for the Shuttle Discovery. Successful launch and they are now docked with the ISS. They have mounted a camera on a special boom extension and attached it to their robot arm and used it to examine the Shuttle's underside for damage. Apparently a piece of foam from the external fuel tank fell off and hit the Shuttle during the ascent stage. The preliminary findings are good, no damage. I am watching NASA TV right now, they are into their first spacewalk, actually they just finished stowing a broken space station antenna in the Shuttle's payload bay, they are now preparing the Harmony Node for installation. Speaking of which the above pic is of the Harmony Node in the Shuttle's payload bay.
