India Launches Hefty Communications Satellite Into Orbit to Cap Busy 2018 (space.com) 48

India successfully squeezed a seventh launch into the year Wednesday, using an upgraded version of the country's Geosynchronous Satellite Launch Vehicle to place a massive communications satellite into orbit for the Indian Air Force. From a report: That communications satellite, called the GSAT-7A, weighs nearly 5,000 lbs. (2250 kilograms) and will allow the Indian Air Force to manage all of its space communications itself, rather than paying for satellite services. "This mission, both in the launch vehicle as well as the satellite, there are so many firsts," K. Sivan, chair of the Indian Space Research Organisation (ISRO), said. [...] Today's was India's last scheduled launch for 2018, although the country is eyeing two launches in January 2019, including of its second moon mission, Chandrayaan 2.

      If everything launched into orbit is, ipso facto "junk", then why worry about junk running into other junk?

    • Big satellites aren't much of a problem, they're easy to track or calculate their orbit. Probably more so in geostationary orbit (sitting above a fixed point on the equator).

      Mini-satellites launched into a low orbit aren't much of an issue either: they will de-orbit and burn up in the upper atmosphere after a relatively short amount of time.

      It's the stuff in between that's the problem: a wrench or a bolt lost by an astronaut during a spacewalk, a part or module that somehow comes loose from a satellite

    • Communications satellites like this one go into geostationary orbit. That's an orbit with a radius of 42,164 km, for a circumference of 264,924 km. There are currently about 1800 satellites (and dead husks) in geostationary orbit, for an average spacing of 147 km between each satellite.

      The space debris problem is primarily limited to low earth orbit (about 150-1000 km altitude). It takes a lot more energy to get up to geostationary orbit, so we don't put satellites there unless we absolutely need it t
      • In any case this is just the dry run for the big one, the resupply contract for the ISS. Next launch will be 5000lb of poppadoms, rogan josh, samosas, and tandoori chicken.
  • Now, after waiting on hold for three hours, I won't have to deal with chopped and dropped sentences when "Brad" from Bell Canada's Customer Service Department explains to me why they have been overcharging me for services I never ordered and don't use.

    • *Sigh* At least on Slashdot, you'd think people would comment on the technical chops to do what ISRO does, rather than try and be funny about Indians doing what American companies pay them money to do.

        Thank you....come again!!

    Another space launch by India; good on them, but do they seriously still believe they should be classified as a 'developing nation' to receive part of $100B as part of the Paris Climate Agreement? China and your moon mission this month - we're looking at you too!

      India is a typical failed nation.

      New Delhi wastes money on military satellites and nuclear weapons when most Indians live in poverty. By contrast, when Poland was an impoverished nation, Warsaw deliberately refused to spend money on military satellites and nuclear weapons; the Polish government spent most of its resources on economic development.

      Today, India remains economically poor, but Poland is relatively wealthy.

      Among the Russian elites, supporters of Vladimir Putin use India to justify rejecting demo

      • Sure, because other than their economic agenda, India and Poland were in a totally similar situation... Come on. Poland did not have a poor underclass at the size and level of poverty that India did. And Poland wasn't all that underdeveloped, it was a relatively modern nation.

        If India focuses solely on fighting poverty, they will be fighting poverty forever. Instead, they choose to also stimulate high tech enterprises. As to allocation of funds: it looks like India saves money by building and launch

      Good point. They have 1.3 billion people in their country, over 60% of whom do not have access to a toilet and yet they are launching satellites that weight as much as a full size pickup truck into orbit. Are they a developing nation? What's the metric?

      • Define toilet? Why do people claim people in India have no toilets?

        • by lazarus ( 2879 )

          Because the World Health Organization told us I guess:

          "India with 626 million people who practice open defecation, has more than twice the number of the next 18 countries combined [who.int]"

          They seem to define Toilet as not practicing open defecation.

          • And who tells us that this is true, or that they in fact have no toilet?
            I mean: did you never piss at a tree?

            I never have been in India, but I find it hard to believe that houses have no toilets or no "outhouse".

            • In india, the open spaces/forest/waste-land which are public land is freely accessible to anyone. cows to graze say. Unlike so called developed nations where they fence it off and ask for special permits (ie u hv political/economic clout) to enter. Human waste gets recycled in such area may be in a cpl of days and rains wash it off too. And for billions/millions of years that's what mammals/reptiles and all other living thing on earth having been doing. This collecting of waste n sewage system is something
      • I don't see how that's a good point at all. You said yourself that 60% of their population doesn't have access to a toilet - how is that not good enough for them to qualify?

        I think you may have confused the word "developing" with "so poor that they're not developing at all."

      India had a very different approach to space tech.
      They could not buy in, import and ask for other nations for "free" help.
      So India had to slowly do the math, science and production lines at its own pace.
      A generation and decades later everything is in place and India is winning.
      Contsider that with the way France, the UK efforts with Skynet (satellite) https://en.wikipedia.org/wiki/... [wikipedia.org], China, the USA started and worked on their rockets.
      Very different approaches, education, workers, laws and budgets.

    Otherwise, India would not have been to pull it off.
  • The Indian satellite is a little over half the weight of the GPS satellite SpaceX intends to launch (9,700 lbs).
