ISRO plans a slew of foreign satellite launches

Today, the Indian Space Research Organisation made public its intentions about the PSLV-C28 mission. 

Through its commercial arm, Antrix Corporation, ISRO has inked a deal with the Surrey Space Centre of the UK. This launch would carry five of its payloads. 

Three of the payloads are DMC3 satellites, namely DMC3-1, DMC3-2 and DMC3-C. These 3 satellites consist the starting point of UK's DMC3 satellite constellation, chiefly designed for high-resolution Earth observation. These satellites will be strategically placed in a Sun-synchronous orbit, while would enable them to image a target on any part of the Earth.

In addition, there are 2 other payloads from Surrey. CBNT-1, a technology demonstrator earth observation micro-satellite, and De-OrbitSail, a technology demonstrator nano satellite.

Accommodating so many payloads within the 3 metre-high payload fairing of the PSLV was indeed a challenge, says ISRO in its press release.

This launch shall use the augmented XL version of the Polar Satellite Launch Vehicle, ISRO's workhorse launch vehicle with a truly impressive track record. For over 20 years, this launcher has betrayed its creators only on its maiden mission.

I know this is getting boring, so, those who are interested, head over to the mission profile and check out all ISRO has to say about its mission (including technicalities):

No official date for launch has been announced as yet. This is one among a series of foreign contracts ISRO has taken up Antrix Corp. ever since the close of the 20th century.

A live webcast of the launch should be available on YouTube and television networks by the State broadcaster, Doordarshan. More updates as they come in.

Into The Sunset

To me, sunsets always look beautiful, and more so when an airplane appears to head right into it.

MOM looks as Valles of Marineris

Which rummaging through the website of ISRO today, I noticed they've quietly uploaded many images from the Mars Colour Camera payload on-board India's Mars Orbiter Mission.

MOM is well past its projected service life of a year, and ISRO suggests it's gonna last at least another 365 days.

A Journalist's Double Life as a French Jihadi Girl: Contacting a fighter of the Islamic State

This article from The Guardian presents how a French journalist went undercover as a jihadi girl in France proposing to contact a fighter of the Islamic State. Her aim was to find out how European children were falling prey to the propaganda of this terrorist group.
http://www.theguardian.com/world/2015/may/26/french-journalist-poses-muslim-convert-isis-anna-erelle

The article then goes on to describe how it was all forced to an end, including the dangers associated with the abrupt termination. 

Do give this is a read. I know, it's a longread, but it's also investigative journalism at its best. This write-up is an extract from the yet-to-be-published book In The Skin of a Jihadist,  releasing this June 4.
When a French journalist posed online as a young woman interested in Isis, she was soon contacted by a fighter in Syria. He proposed marriage – but could she maintain a double life?

This is insane, and surely deserves a bookmark.

We've all wanted to see this, but had (probably) never seen it until now. But here it is in front of our eyes: the emission spectra of all elements of the Periodic Table.

Model-Dependent Realism in Biology

It turns out that there is a problem with the way we're currently doing biology, and resolving it promises to change the very way we do this science.

My take on the transformation required in methods of investigation of biology, in order to overcome current dead ends:
http://astwavelength.wordpress.com/2015/06/12/model-dependent-realism-biology/

Biology needs to get more comfortable with model-dependent realism. We need more generalized models, that think of biological systems as electronic circuits, for instance. That's the only way forward from us getting stuck in a maze of gibberish while attempting to explain biological systems at the cellular level. 

Leave your comments and opinion too!
There is a problem with methods of scientific investigation used in biology. And resolving it promises to radically alter the very way we do this science.

Let Me Have a Drink Too!

This little dog probably is very well aware that the makeshift island of sacks is intended for construction workers.

But surely, that shouldn't be reason to abandon his daily gulp of water by the place every evening!

It may be a 4-star hotel, but one doesn't get the feeling of a 4-star hotel upon entering it. Leave alone from the outside, you don't get that feeling when inside either. The Eco Hub is much better than this. Maintenance is not fine. Although I haven't stayed here, the hotel doesn't seem very attractive from the outside as a 4-star hotel. A lot of improvement is required, and expected from The Pride Hotel, as a 4-star hotel in a future posh location such as Newtown (India).

It is a world-class destination for those who want to party or just take a swim, and do all that like to while away time. A monthly membership gives you access to all the facilities, which include a gym, swimming pool, badminton court, etc. It is very beautifully decorated. I would personally recommend anyone going there to visit the place at night, the decorative lights are wonderful.

The place is a good centre of knowledge. But it doesn't attract much people, rather appeal to the people. They should try to make the place more appealing to the people, so as to increase the footfall, and thus their revenue and the layman's knowledge about science. An average place in general.
