Chandrayaan 2 Design Completed

25 12 2008

Indian Space Research Organisation (ISRO) said the design for the second moon mission, ‘Chadrayaan 2‘ is completed on December 24th, Wednesday. The mission is supposed to carry a lander/rover whereas the mother spacecraft will orbit the Moon. Chandrayaan 2 is said to be launched on 2012.

ISRO has collaborated with Russia for building the rover. The rover will have a soft landing on the moon unlike the MIP probe of Chandrayaan 1 which had a hard landing. The rover will collect the soil and rock samples from the moon, do in-situ tests and send the data to Earth through the orbiter. The estimated cost for Chandrayaan 2 is said to be Rs. 425 crore (US $ 90 million).

ISRO is currently earning about Rs 10 billion (Rs 1,000 crore) annually from its commercial wing. Chandrayaan is expected make it grow at 20 percent per year.

Anyways, I forgot to mention this in my previous post. The previous one was my 50th post. :)

Picture Of The Month – December 2008

18 12 2008


This is not a very clear image but it is an astonishing one of the crescent Moon and Venus. This was viewed right here at Chennai on May 21st, 2004. It may be old but I would never forget this incident where the Moon forms a magical lamp with Venus brightly light at the end. This image was published in “The Hindu” on the next day. Ever since I started this blog I wanted to post this image but I never found it. By mere luck I found the old newspaper with this image and using its date I found the image in “The Hindu” website. I now hold the newspaper cutting (where the image is clear) as a possession. Click Here to read the article.





A Halo!

18 12 2008

I remember my friend Kavin, who use to ask me repeatedly, “What is an Halo and how it is formed?”. I had no answer to this question except that I knew it occurs quite regularly. So finally I decided to check on what an Halo is, and this is what I found.

Halos are nothing but a dim circle of light that is formed around the Sun or the Moon or any bright source of light for that matter (eg. a street lamp). These halos are formed due to ice crystals that are found in the clouds. These ice crystals acts as a lens reflecting and refracting the light.

Geminids Experience

17 12 2008

It is the day of Geminids. I had a very long, horrible day throughout. The worst day of my entire life had a happy ending with about 5 meteors. Click here to read the experience of my day. Due to various reasons I reached home as late as 11 pm. I went straight to my terrace at around 11:15 only to find most of the sky covered in clouds. I realized that the clouds were moving very fast and within 10 mins they must clear. Just as I thought the sky was cleared in 10 mins making the sky, around Gemini, clear. The Moon was very bright and I was sure to miss out lots of meteors. I positioned myself such that I could see all around Gemini especially the western part of the sky.

11:39 – South-west, 80 deg from the horizon, a short meteor. Not the brightest.

11:48 – This one was a little to the west from zenith (exactly over-head). It was very quick and very short. It was very quick and also being short, it disappeared less than a second.

11:55 – About 60 deg from the northern horizon, moving towards west. It was a little bright and longer than the previous two.

This was when a bunch of clouds came in. Had to wait a long time for it to clear.

12:15 - About 45 deg from the western horizon. It was less bright but it was quick.

12:30 – About 60 deg from south-west horizon. This one was bright and it moved slowly, about the normal speed with all others being too quick.

The long tiring day started to take over me and I realized I almost dozed at the terrace. I decided to get back into the house and sleep. But it was a good experience.

I hope atleast one of my friends had caught one.
