Dragon Captured in Space

"Houston, looks like we got Dragon by the tail", Don Petit, astronaut in ISS controlling the Canadaarm2, announced.
SpaceX's Space dragon capsule has been roaming around the ISS for about three days. It carries cargo to ISS. After sophisticated tests and affirmation that Dragon will not be harmful to ISS, it has now been captured by a robotic arm. The process known as Berthing.

On May 22nd, @SpaceX  uccessfully launched the #Dragon capsule into orbit! 
This is the new venture to commute to the international space station (ISS) through private efforts and is the first commercial resupply vehicle to ISS. (http://www.bbc.co.uk/news/science-environment-18154937)

Here is a tweet linked to the beautiful arc when SpaceX lifted Dragon to space.

Solar Eclipse in East Asia and North America May 2012

Clouds permitted, we will be observing a solar eclipse this weekend on 20-21st May 2012.

The Annular Solar Eclipse of 2012 May 20/21

Update: We came up to higher ground and waited for the Eclipse time. Only to be disappointed. My colleague Marc referenced it as Murphy's law striking.

Yes, there is an app for that! (See my android astronomy here.)

 After about an hour, I gave up and turned towards home. Then the Sun peeked from a space between the clouds! It was just before the sun was setting. I captured the moment with my cell.

Listening to the data by sonification

When you get a good chunk of data, what do you do first?

You probably plot different aspects of the data, trying to identify the patterns and characteristic signatures in it. Well, that is very helpful for visual people. 

What would auditory people do? they listen...
"Shhhh. Listen to the data." A Physics Today article by Toni Feder.
The process of converting the data to streaming sound is called data sonification. Sometimes the visual data is too noisy. Ear may be able to pick out the subtle structures in the data.
A quote from the article:
“When Voyager 1 flew by [Jupiter’s moon] Io in 1979, we detected whistlers”—low-frequency radio waves. “That was first detected by hearing. Your ears are amazing at picking out fine signals. In frequency–time spectra, you can choose the resolution when you process the data. If you choose the wrong resolution, you may not detect anything. You have to match what you are processing to the time resolution. Your ear does that automatically.”

Thanks to my wife for typesetting it.

End of mission for Envisat declared by ESA

Environmental Satellite or Envisat, launched in 2002, is one of the most successful earth observing (remote sensing) missions. With 10 optical and radar instruments onboard, it celebrated 10 great years in orbit. However, on 8th April 2012, it lost communication to its command center.

The team had been trying hard to re-establish the communication; no success. Therefore, ESA has declared end of the mission for Envisat. In the press release, they said that they will keep trying for next two months. We would like to wish them a success!
