India going to study the Sun

Immediately after the successful launch of Chandrayaan-I, then ISRO Chairman Madhavan Nair announced Aditya-1, a spacecraft to study our Sun. Updates coming over the last one month have updates on this ISRO mission as well as interest in Solar Physics.

Aditya-1 is a 100 kg spacecraft under development by ISRO in association with Udaipur Solar Observatory, Indian Institute of Astrophysics, Radio Astronomy Centre and National Centre for Radio Astrophysics. This Rs. 50 crores space based solar observatory will be in a 600 km low Earth orbit and is expected to fly in 2012 close to Solar Maxima.The spacecraft will

Reports indicate that the Indian Institute of Astrophysics has completed the design of the solar coronagraph. ISRO is working on developing the detectors and thermal structure. First spacecraft prototype is expected in 2011. While the main idea is to study coronal mass ejections (CMEs), ISRO hopes to utilise the data to know how to better protect its satellite systems in orbit.

The IIA is also involved in the development of a ground based solar observatory in the Himalayas with national and international mission. The fabrication of the telescope is expected to begin in 2010 with IIAp has already floated the tender.

Foursquare Day #4sqday

Foursquare day is called so because in the American calendaring
system, the format used is mm-dd-yyyy. In this scheme of things, this
date reads, 4.16 or four and its square – shortened by the twitter
world to foursquare.

The experience of getting to Candies (a sweets place, I thought!) was
terrible. Getting down at Pad. Mohd Rafi Chowk, every time I asked
directions, I was told the place was only 5 mins away. I asked this 4
times and got the same reply. After the last ‘it’s just 5 mins away’
remark, I had given up hope when I saw the nameplate (?). This wasn’t
the end of things. I then had an equivalent of the ascent of Mount
Everest climbing up stairs. Finally summited to a round of applause!

We discussed important questions like what was foursquare, what  the
people’s twitter handles, what to eat, what a corporate hack did,
kisko mala pehnaya jaye etc. Enjoyed it totally.

I took leave, took a strangers suggestion and got into a bus, got off
at Bandra Stn, stood in the wrong bus stop for 15 mins, got into a
cliff hanger bus, got into an auto at Sion where it had to stop
because of a traffic jam and then returned home.
