India Targets July/August To Test Its Space Shuttle
New submitter gubol123 writes with news that India is close to launching its own space shuttle for the first time. Their space program, ISRO, is planning the shuttle's first test flight for some time in July or August. The unmanned shuttle will fly to a height of approximately 70 kilometers before splashing down in the Bay of Bengal. Oddly, the vehicle itself probably won't be recovered. When it lands in the water, it will sink, and there are no plans to try to bring it back to the surface. The most important obstacles are surviving re-entry and simply staying intact during splashdown. Scientists and ISRO engineers are hoping the shuttle program, when finished, will drop the cost of placing objects in orbit by a factor of 10.
The term shuttle in murican terms is a piloted thing that lands under control. this seems more like a reusable space container?

How can it be called a Shuttle if it's only going to be used once?
I wonder if the X-37B will be taking pictures?
I'm very surprised that they wouldn't be at least planning to recover the craft - that would give them all sorts of validation about the actual impact (heh) of launch and re-entry, and could help them get to the next iteration faster. I assume they know what they're doing, but TFA didn't include anything approaching a reason for not attempting recovery.

Wouldn't it be more cost effective to outlay a bit more initially so the darned thing can land on a runway, or at the very least just deploy some inflatables so it can float until recovered?
The original US Space Shuttle was also designed to reduce costs - It was hoped that it would be able to run 50 missions / yr (one per week!) and cost $50million/mission (in 2011 dollars). Instead, reality set in, and by the end, it was running only a few missions per year at a cost of around 1/2 Billion dollars each.
The Space Shuttle, while a novel idea, simply wasn't the best design for getting into space - it introducing too many safety compromises. Granted, technology has vastly improved since the 1970's, when the Space Shuttle was designed, but that's mostly in the area of computing - material science hasn't changed nearly as much.
I truly hope India does well with their program, but I do wonder if they're ignoring the mistakes made by the US when we went down this road.
Also... 70km... They do realize this isn't planet Kerbin, right?
the US space program had one OV structural test vehicle and one airframe mockup. The test vehicle was refit for service (and became Challenger), the airframe mockup named Enterprise and sent to a museum. Enterprise never actually went into orbit. She was used for atmospheric glide and landing testing. Judging by the amount of money those two vehicles alone cost in construction (never mind development), which had to be a lot since Challenger's replacement, Endeavour, cost $1.7Bn and was built out of spare parts, it's great to see India's economy doing so well that it can afford to throw test articles into the sea and let them sink.

It's interesting how individuals care about their nations image, over anything else...

The outsourced coding joke just kind of writes itself, doesn't it?
Re-entry from only 70 km isn't exactly re-entry. It hasn't even been in space at that height...
Sig?
The Karman line is 100km. This thing is a suborbital. It's not going to space.

This vehicle is a low-cost testbed, which will be use to validate the technologies required to build a larger vehicle: the TSTO (Two-Stage To Orbit)

The eventual holy grail is to design, build and fly an SSTO (Single-Stage to Orbit) vehicle called AVATAR which would use scramjet technology. The scramjet-to-orbit concept is considerably more difficult, and may take much longer to accomplish.
Meanwhile the TSTO would just use regular rockets (semi-cryogenic booster & fully cryogenic for upper stage). Multiple copies of the cheap RLV-TD have been built, and will test different technologies across multiple flights, including the scramjet (on a later flight).
I'm more interested in the TSTO, which is supposed to be built from technologies to be validated by RLV-TD. The TSTO will help to bring down cost-per-kg to orbit. Basically, it's a 2-stage launch vehicle based on a winged flyback booster. It won't be as efficient as the F9R, which doesn't carry the weight of wings, but it will be more capable of returning to launch site because of its glide path. No barge required.
The first US Space Shuttle, the Enterprise, didn't shuttle a whole lot of stuff back and forth either. But it was meant for developmental purposes, and wasn't the final product.
This has nothing to do with nuclear delivery systems - India has separate military-run programs for that. This is a civilian program under a civilian agency, and the technologies involved aren't the best-suited for ICBMs.
I don't see why it's not obvious for everyone that this is a test for the Indian nukes for ICMB under cover of a space program. It's interessting to see that we don't apply the same understanding for North Korea than to India. Both have Nukes, both wants to go further with those nukes.
I'm pretty sure if India attempts to land this thing without warning anyone (e.g., designating a no-sail-zone) into Arabian sea just 200km outside of Karachi, I'm sure that people will be looking at this as an "unwarranted action" like North Korea.
Space is the past, why are countries so hell-bent on these big symbolic Pyramids in the sky?
There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?
We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.
