India Launches 10 Satellites At Once 201

Posted by CmdrTaco from the i-can't-even-juggle-two-satellites dept.
freakxx writes "India sets a world record after launching 10 satellites in one go using its workhorse, the Polar Satellite Launch Vehicle (PSLV). All the satellites were put into their respective orbits successfully. It was the core-alone version of the launch vehicle weighing 230 tonnes with a payload of 824 kg in total. Two of the satellites were Indian satellites, while the rest were from different countries. By this launch, the ISRO has proven its credibility and it is going to boost India's image in the attractive multi-billion commercial market of satellite launches. This was the 12th successful launch of the PSLV."

      Here's a funny thought:

      1. India has nukes. (It also sits on huge reserves of Thorium and has breeder reactors, so it can transform them to uranium or eventually plutonium, as needed.)

      2. If you can put an object in orbit, you can make it come down wherever you want it to come down. Or use a smaller rocket and/or a heavier load to make them go ballistic instead of orbitting at all. (For reference, the USSR's space program started the other way around. Someone realized that they had build a rocket so powerful to haul nukes, that it could put a small-ish object in orbit.) Rockets are that interchangeable purpose.

      3. Inclined/polar orbits? Always good to have for a nuke, if nothing else, to hit a location that's not near the equator. Plus you might want to go extremely inclined to minimize flight time and thus warning time (I think both the USA and the USSR had most of their nukes aimed at each other over the arctic), or to lob them over international waters and avoid pissing off everyone else in their path.

      As a bonus: once you can do polar orbits and big payloads, you can use spy sats.

      Now I'm not saying India is necessarily aiming to become an ICBM power. Maybe, maybe not. And they're probably not yet ready to willy-wave internationally about it, in any case. But I'm saying I wouldn't be the least surprised if that was at least one factor in funding that space program.

      I still remember seeing the news on TV when they had built their first nuke, and the general euphoria. It was waay back, while they were even poorer than today. Arguably that money could have been better invested in industrializing a little faster. But there were people cheering in the streets that they now have a big destructive weapon. I can see a lot of political capital in the implicit "and now we can lob it at anyone too!" message.

      Now I'm not singling India out there. I think they're just... humans, like everyone else. And it's a sad thing that we'd rather have a big stick to threaten the neighbours with, than an extra slice of bread.

        Not all countries' space programs are about war and weapons. some are less paranoid.

        The 690kg CARTOSAT and the 83kg IMS-1 are both remote sensing satellites, equipped with panchromatic (B&W) and Spectral cameras to image earth at visible and infrared frequencies. Many, if not all, indian satellites are for remote sensing/meteorological - because in a country where agriculture is the primary industry, it is paramount to track the movement of rainfall, particularly the seasonal monsoons. These weather predictions are vital for farmers to ensure a good harvest. A good harvest leads to lower food prices - in effect, this launch has a very close relationship to feeding India's poor, contrary to many trolls here.
        The focus of India's space program has, thankfully, been always about peaceful purposes while making money on the side by providing a cheap option for launching amateur radio/science project satellites built by students and universities (such as the other 8 in this launch). More info about the launch here [isro.org].

        As an interesting side note, the PSLV will also be used for Chandrayan-1, India's first mission to moon.

        India also has uranium/plutonium for enough nukes. So why bother with the thorium route. Anyway, we are preserving our supply for more *interesting* applications and shopping around for an independent source of uranium for power, courtesy the nuke deal.

        India's guided missile program (Agni) is known to borrow heavily from it's civilian space program - this is true.

        However, it's important to note India's proven track record as a non-agressor, which is especially remarkable when you consider that its surrounded by hostile parties in one way or the other.

        India's first nuke test was in 1972 [wikipedia.org]. That's 36 years of indigenous nuke capability. In that time, they have been in a constant state of tension with Pakistan (and gone to war once - Kargil), had a prime minister (Rajiv Gandhi) asassinated by the LTTE (Sri Lankan militants), have parts of Kashmir and Arunachal Pradesh (another state of India) occupied by China, have ULFA seperatists operating in Assam (a north east state of India), and have constant tensions at their border with Burma and Bangladesh.

        Not once in this time has India used it's military in anything other than a defensive role. If India's neighbours (and indeed the rest of the world, and especially the US) showed that much restraint, the world would be a much better place.

      From Wikipedia:

      Galileo is intended to provide more precise measurements to all users than available through GPS or GLONASS, better positioning services at high latitudes and an independent positioning system upon which European nations can rely even in times of war or political disagreement.
      It might be redundant for many positioning applications, but completely worthless...?

      According to the same source, the EU is spending 3.4 billion Euros on this. This is just half of what we're spending on "administration" this year, and considering the other truly worthless crap we are spending money on, having our own GPS system is a pretty good goal in comparison.
