    These peanuts are given to Non Government Organizations (NGOs) like Amnesty International & Greenpeace India and so called freedom fighters in J&K if you know.

    On the other hand, India itself is a donor of aid which dwarfs British "aid" budget.

    These guys got lucky for a short period of time,and are now are sliding to irrelevancy, just enjoy the stomach burn :lol: In fact them demanding to reduce funding is actually a good thing, the "aid money" actually works to create propaganda against us, with ngos like oxfam, and buys them influence. Most of the money rarely even leaves the UK. So them wanting to stop it is actually great!


    If we take a look at all the stuff, they'd have to give up their island some 10 times over and it still would not be enough :lol:


    ISRO to launch record 103 satellites in one go in February


    The space agency had earlier planned a launch of 83 satellites in the last week of January, of which 80 were foreign ones.


    ISRO will launch a record 103 satellites in one go using its workhorse PSLV-C37 in the first week of February, while Prime Minister Narendra Modi’s pet South Asian satellite project will take off in March. As many as 100 of the satellites set for launch in February belong to foreign nations, including the US and Germany. “We are making a century by launching over 100 satellites at one go,” said S Somnath, Director of the Liquid Propulsion Systems Centre of the ISRO.

    The space agency had earlier planned a launch of 83 satellites in the last week of January, of which 80 were foreign ones. But with the addition of 20 more foreign satellites, the launch was delayed by a week and will now take place in first week of February, Somnath said. He, however, did not specify the number of countries that would launch its satellites in this mission, but said it includes nations like the US and Germany. “These will be 100 micro-small satellites, which will be launched using a PSLV (Polar Satellite Launch Vehicle)- C37. The weight of the payload will be 1350 kgs, of which 500-600 kgs will be the satellite’s weight,” Somnath added.

    The launch will be a major feat in country’s space history as no exercise on this scale has been attempted before. Last year, ISRO launched 22 satellites at a go and this launch will have almost five times the number of crafts. The South Asian satellite will be a part of GSAT-9, which will be launched in March this year, said M Nageshwara Rao, Associate Director of ISRO. The communication satellite was to be launched in December 2016, but was slightly delayed as some other satellites are to be launched before that.

    Sources said talks with Afghanistan to have the country on-board for the project is in its final stages. Envisaged as a gift to its neighbours, the project, earlier known as SAARC satellite, faced stiff resistance from Pakistan. The neighbouring country wanted it to be launched under the aegis of the South Asian regional forum. It later backed out of the project. Apart from India, the satellite will benefit Sri Lanka, Maldives, Bangladesh, Nepal and Bhutan.

    About VSSC's Finite Element Analysis of a Structure (FEAST)

    FEASTSMT (Finite Element Analysis of Structures) is ISRO's structural analysis software based on Finite Element Method (FEM) realized by Structural Engineering Entity of Vikram Sarabhai Space Centre (VSSC). The software is developed in C++ Programming Language based on Object Oriented (OO) principles. Substructured and Multi-Threaded (SMT) implementation of the solver ensures high performance of the software to the end users.

    PreWin is the Graphical User Interface (GUI) based pre & post Processor of FEASTSMT. It is developed using OpenGL technology for the 3-D visualization of Finite Element models. The software is integrated as a single application with PreWin, supporting the pre and post processing capability and the SMT solver, linked as a dynamic library (DLL) providing the solution.

    Analysis Capabilities:

    The current version of FEASTSMT 2014 R2 includes linear analysis capabilities. This is packaged in a modular form for academic and commercial usage by combining the basic and supplementary module.

    Basic modules

    • Linear static analysis
    • Free-vibration analysis
    • Buckling analysis
    The following supplementary modules are bundled with basic modules as per user requirement.

    Supplementary Modules
    • Transient response
    • Frequency response
    • Random response
    • Fluid-Structure Interaction
    • Base excitation

    Back in 2014

    A message to Indians, Remember when you wet your pants in 1998? Don't make that same mistake again. Just because we haven't done it YET, doesn't mean we never will.
    Pakistan's National Defense Complex or NDC began developing its own Satellite Launch Vehicle in 2001 and have secretly completed it as early as mid-to-late-2008. It is rumoured to be currently housed at MTFR Jhelum near the Tilla Satellite Launch Centre and is awaiting its launch. The exact details of the SLV have not been made public - in fact both the government and military deny it even exists. Two models have been made - the first model "Taimur 1" consists of a three stage solid-fuel 25m vehicle capable of transporting small scientific payloads into low Earth orbit. The second model or "Taimur 2" will be double the first stage of the Shaheen-2. During IDEAS 2002 Defense Exhibition, PakDef spotted two similar models of Satellite Launch Vehicles. The first model points out a possible three stage SLV - judging from other similar SLV's, it is estimated that it can place a payload weighing less than 80 kilogram to an orbit 450 kilometers above Earth's surface. The second model of the SLV seems similar to the first model however, with four extra boosters (Abdali?). Exact details have not been made public. Pakistan is rumoured to unveil the Taimur SLV in 2015-2016 when the Space and Upper Atmosphere Research Commission (SUPARCO) completes its first round of GEO satellites (Paksat-MM1, Paksat-MM2, Paksat-II) and LEO satellites (PRSS series).

    2017 has arrived and I still can't see them having capability of placing even 50 kg in LEO in near future.:D

    Wikipedia says program is dead though.

    Mere azeez hamwatno, Is launch ke baad Pakistan ek aitmi kuwwat ke saath saath gardish mein sahlaayi mission bhejne waala waahid musalmaan mulk ban gaya hai. Alhamdulillha yeh humaare sciencedaano ke josh, jazabe aur imaan ka saboot hai aur iske saath humne india ko bhi pachaard diya hai....

    Inshallah, Cheen se agla rocket milne par.....merrraa matlab hai...humaare sciendaano ke naya rocket taiyaar karne par hum 3 kilo ke bajaaye 4 kilo ki satellite launch kar sakeinge.

    Please...let's not pollute ISRO thread with this Pakistani nonsense. It's doubtful this Taimur can even compare with the SLV-3 we built in the 1980s. And that's if we assume it actually exists.

    Either way, you are free to open a SUPARCO thread in Pak section where we can dump all this bogus content.

    Masha allah !!

    urdu zuban or uske talaffuz pe badi mazboot pakad hai apki :p

    btw heres something related to this

    http://www.dawn.com/news/79439/satellite-to-help-promote-education-musharraf-launches-paksat-i

    “Pakistan’s space programme is now ahead of India after the formal launching of Paksat-I and this is due to the hard work of our scientists and I am sure Indians would take another 30 months to do the job,” Gen Musharraf claimed.

    FUTURE LAUNCHER PROJECTS

    GSLV Mk-3 (LVM3)
    [​IMG]

    First launch: 18 December, 2014
    Status: Testing
    Height: 43.43m
    Launch Mass: 640 tons
    Payload to LEO: 8000 kgs
    Payload to GTO : 4000 kgs

    --

    Unified Launch Vehicle (ULV) Program
    [​IMG]

    Status: In Development
    The ULV is a whole family of launch vehicles being developed to potentially replace all earlier launchers with a common, customizable platform. As the picture above shows, the specs are listed from the smallest to the biggest configuration touted to be in the series
    Height: Unknown, fairly similar to LVM3
    Launch Mass: 270 tons (min), 700 tons (max)
    Payload to LEO: 4500 kgs (min), 15000 kgs (max)
    Payload to GTO: 1500 kgs (min), 6000-6500 kgs (max)

    --

    Re-usable Launch Vehicle (RLV)
    [​IMG]

    First launch: 23 May, 2016
    Status: Testing/Development
    Only the TD (Tech Demonstrator) has been flown so far, and it is roughly similar in size to the Boeing X-37B spaceplane (or the X-40 demonstrator that preceded it). The RLV is designed to incorporate the concepts of reusable technology with Scramjet/hybrid propulsion. The completed RLV will be around 6 times the current size, will take off horizontally from runways, deploy it's payloads and land back on ground under it's own power. Very similar in concept to the Skylon project. Both manned & unmanned variants will be made.

    Heavy/Super-Heavy Launch Vehicle (HLV/SHLV) Projects
    [​IMG]

    In early stages of design & development are heavier LVs designed to throw larger, potentially habitable payloads into LEO, SSO, GTO & Lunar Transfer orbits. Expect LEO payload capacities to start in the region of around 25,000 kgs and eventually go up to 100,000 kgs at some point. It's believed that the first HLV might be developed from the biggest ULV variant, making it an unofficial part of the family.

    One thing is clear - ISRO is really looking to step up international cooperation in space. Joint missions with Russia/US are a possibility in the near/not-too-distant future. Recent meetings with NASA are proceeding toward that goal.

    Let's hope it'll all be an eventful & exciting journey, for scientists & civilians alike!
