An artists video of the UARSs uncontrolled fall on Earth

UARS set for a glorious self destruction

As UARS (Upper Atmosphere Research Satellite) reaches its end of a productive 6 years of research, the world awaits its glorious self destruction as it enters earth's atmosphere on Sep 23rd 2011. It is supposed to enter the Earths atmosphere US time on the 23rd but the exact location is still unknown. As it burns itself while entering the atmosphere, scientists say, it can glow as bright as Venus. Hope to get a glimpse of this historic event.


As Sep 23rd is getting close, NASA is getting a clearer picture as to where this doomed satellite will enter earths atmosphere. Feel free to visit this page for the latest info. http://www.nasa.gov/mission_pages/uars/index.html

Below you can see an Artists image of how it might look from up above.

I am from Southern California and maybe I am too optimistic, but wish it enters on the west coast and falls in the Pacific Ocean. Its will be a beautiful site to see.


Fingers crossed.

My first Astro image.

For an amateur astronomer, it’s an Amazing feeling to take my first astro image! I have been trying to take a picture of the moon for quite some time now. Finally I have some success. Believe me guys it’s a treat.

It took me a few months to figure out what the problem was. It was a focal length issue and the webcam image sensor was not able to reach the focal point of my Zhumell 10 inch. I took out the image sensor from the webcam and placed it half way into the eyepiece hole. Luckily, the hole was big enough to accommodate the image circuitry. I taped this arrangement inside the eyepiece to avoid any disturbances. With little adjustments to the eyepiece focusing...BAM! I had the image of the moon.

So for guys who are trying to take a picture of the moon with a webcam and you see that your image is blurry no matter what you do.. You know it’s a focal length issue. Just try to do what I did above and you should be able to get a view. I used wxAstrocapture to record an AVI file and then used Registax 6 to process the image. I know that there are tons of images of the moon out there... but for me this image will always be special.

My first astro image! A processed file.



Specifications of the instruments used:

A Zhumell 10 inch dobsonian (No equitorial mount)

A logitech webcam (CCD sensor, non moded)

and A laptop :)

Meteor Lights Up Georgia Sky

A Man-Size Meteor From Comet Lit Up Georgia Sky yesterday...
The 6-foot-wide (1.8-meter) space rock barrelled into Earth's atmosphere at 10:47 p.m. EDT on May 20 (0247 GMT on May 21), about 66 miles (106 kilometers) above the city of Macon, Ga. Two NASA all-sky cameras, both located in northwest Georgia, tracked the resulting meteor and captured it on video.

Just a thought though!

All of this is cool.. But we have advanced so much in space technology that NASA should be able to build a "go getter" space shuttle that goes outside of earths atmosphere, breaks down the meteor and gets a part of the meteor safely down to earth. I am sure that there would have been an era of space history lost when the meteor burned down to ashes, when it entered earths atmosphere.

Yesh.

Bitter Sweet

Bitter Sweet - A term that is being used now a days to descride the current mind-set @ NASA.

After 30 years of spaceflights and more than 130 missions ISS is finally complete. NASA's space shuttle fleet will retire and be on display at institutions across the country to inspire the next generation of explorers and engineers. I am a Californian and its certainly a great news that Endeavour, that will be on its way back to Earth very soon, will be housed here in LA. All mixed feelings...I guess m getting into a bitter sweet mode myself.

Celebrating 50 Years of Humans in outer Space

Congratulations fellow Astronauts!

It almost feels like there was so less time and we have achieved so much. Yuri Gagarin, made the first orbit of Earth today, 50 years ago. Since then, there was no looking back and man has reached new bounds in outer Space. Bravo!

NGC says "there is something we'll never know about Gagarin's flight, even in the age of Wikileaks: What did the farmer's son from Klushino, Russia, see from 200 miles (322 kilometers) above Earth on April 12, 1961?"

Moon will NOT eat up Earth tonight!

Yes Moon is closest to Earth tonight...Yes, this is the biggest full moon in 18 years... and Yes, it will be a beautiful sight to watch, provided you dont have clouds...like I do :-(

So really, how big are we talking about here? NASA says the moon will appear 14 percent larger and 30 percent brighter than usual. Moons gravity acts on Earth everyday to cause tides and today will be no different or, will be a day with minimal difference(proably a little higher tides... and thats about it). Thats what NASA says... Anyway, if you see or read stuff like there will be earthquakes or floods or tsunamies... my personal openion... "its just a media hype".

There is no reason to panic. So, rest assured... layback and enjoy the beautiful sight today, as it will not occur again until you have grown at least 20% grey hair in 2029.

Great News. Life found in outer space!

Knew this day was not far..

This is breaking news... and will be evaluated... evaluated... and re-evaluated over the next few days and months, but a NASA scientist, Dr. Richard B. Hoover claims that he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite. That's an awesome claim.
Below are two pics of the fossils of the bacteria found in the meteorite.

Dr Hoover says "The exciting thing is that they are in many cases recognizable and can be associated very closely with the generic species here on earth"... which is cool! He further says "There are some that are just very strange and don’t look like anything that I’ve been able to identify, and I’ve shown them to many other experts that have also come up stump."

However, given the controversial nature of this claim, his paper will be examined by hundreds of experts all over the world over the next few days. If this discovery turns out to be true, the implications for human life will be staggering.
Here we come aliens...Oops! too early for that.

Apophis, the Planet Killer to Hit Earth in 2036???

Apophis, derived its name from an Egyptian myth, meaning... A demon serpant of darkness.


Here we go again! It was in 2004 when NASA scared the heck out of people and this time its the Russians. Dont take me wrong... All due respect to both the organizations for keeping track of such objects well in advance.

Here is the thing, there is 1 in 250,000 chances that the "Planet Killer" will hit Earth. Its comforting to know however, that in one of the International NEO (Near Earth Objects)meetings in 2005, it was decided that more research needs to be done on how to avoid that "1" chance of impact. Since then there have been numerous ideas on how to avaid that impact.

Just to give you an idea of how large this asteroide is...it is larger than two football fields and cause more damage that 1000 Hiroshimas blown at once!

The asteroid will come really close to the Earth in 1929 and will cause it to change its path by an angle due to Earths gravity. It will continue to rotate around the Sun until it gets back to Earth on April 13, 1936. There is very very little or no chance that it will hit Earth in 1929 but what will happen in 1936 is still a little fuzzy. It seems we will have to wait until 2013 before we get a clearer picture of what will happen then.

There are certainly tons of reports that conflict the probability of such a doomsday event on the internet, but the question remains: How scared should we be?

Astrophotography with a Dobsonian

I have been surrounded by quite a few interesting things over the last few months. Here is what I have been doing..."Researching" ... Researching on Astrophotography!

Fact: It is not possible to take GREAT pictures with a Dobsonian... Agreed!
Truth: It is possible to take reasonably good pictures with a Dobsonian.

Let me explain...

Astro enthusiasts know this already, that celestial objects are not stationary in the sky... they keep moving... well, not exactly... Earth spins and so it appears as if the celestial objects are moving. In any case it appears as if they are moving. Now, with a dobsonian, one will have to manually adjust and align the object under observation repeatedly... which could be quiet some pain(especially at 300 and above magnifications the objects under observation travel pretty fast).

Concept for equitorial mount: In order to have the object under observation at the center of the viewer... we will have to compensate for the motion of the Earth (Earth rotates from west to east... hence all objects appear to rise from the east and set in the west). Compensation would mean... if we place our telescope on a devise that rotates it in the opposite direction to that of the earth... the earths motion and the telescopes motion will cancel each other and the object of observation will remain "still" at the center of the viewer.

Method: After a lot of research, I found that the equitorial mount will be the best solution. Building this would take a little bit of engineering drawing, little electronics and carpentary. If it sounds hard... well... it is!

By the way... you must be thinking what has Astrophotography got to do with all of this.

Concept for Astrophotography: Taking pictures during night(or on low light) is tough. as the exposure that the camera gets to the light is very less. Low light photography is done using long exposure. There are ways to do this using a ccd webcam(in my case a Logitech QuickcamPro 3000... these CCD webcams are not in production anymore so I bought one on Ebay for $45). You will need to do some modification to the circuit and a little soldering to the webcam circuit board. For a long exposure shot.. the object under observation needs to be focused at the center of the viewer for a long time( 5 sec, 10 sec, 1 min... etc depending on the object). Hence the Equitorial Mount, as it will not be humanly possible to keep the object at the center of the eyepeace manually.

Now-a-days I am trying to build this total setup from various sources available on the internet. It will at-least take me a month or so to complete this whole thing.  I plan to do a tutotial with pictures, for those of you who might be interested. Will update my progress on regular basis. Stay tuned and feel free to leave comments.

Clear skies!
