Full Solar Eclipse 2010 in Tamilnadu, India

Full Solar Eclipse in Tamilnadu

A full solar eclipse was seen at Kanyakumari, South of Tamilnadu, India which is called as Kanganam (Ring or Bangle shape) Solar Eclipse. This is also called as Ring of fire.
This is wonderful to see after a long gap say 108 year. This eclipse started on 15.01.2010, 11.45 am to 1.20 pm and the full eclipse lasted for about 10 minutes. The moon covered fully the sun during 1.10 to 1.20 pm.
The last time India saw this ‘Ring of Fire’ was November 22, 1965. The next longest annular solar eclipse will only be seen in 3043. I watched this amazing event only on TV.

This robot is equipped with a micro motor with four wings which can flutter 30 times per second. It is controlled by an infrared sensor for controlling left, right, up and down movements.

The robot weighs only 2.6 grams (0.09 ounces), However it can not stay at one point at the mid air. Their next step to do research to make it hover at one point in the mid air. They have also planned to fit a micro camera with the robot in order to help rescue humans trapped in destroyed buildings during earthquake, search criminals or to probe vehicles on other planets.

This wonderful robot cost about 2.1 million dollars for design and developed. Though this is too costly, the robot seems very amazing in the technology era.
