Isro's plan: A rocket that can be made in 3 days

Surendra Singh| TNN | Updated: Nov 22, 2017, 08:34 IST


HIGHLIGHTS
    • Mini-PSLV can be built at a cost of just 1/10 of original cost.
    • The manufacturing cost of a launch vehicle is generally in the range of Rs 150 crore to Rs 500 crore across the world.
    • The Indian space agency has started working on the idea of building this small rocket keeping in mind the emerging market of micro or nano satellites.


NEW DELHI: In a development that will revolutionalise the satellite launch system in the country, Indian Space Research Organisation (Isro) is developing a small launch vehicle that can be assembled in just three days as compared to 30-40 days for a normal-sized PSLV and can be built at a cost which will be just one-tenth the original manufacturing cost of a PSLV. The manufacturing cost of a launch vehicle is generally in the range of Rs 150 crore to Rs 500 crore across the world.

Dr K Sivan, director of Thiruvananthapuram-based Vikram Sarabhai Space Centre (VSSC),on the sidelines of an international seminar on 'Indian Space Programme' told TOI, "Isro is busy developing a small launch vehicle which is likely to be ready for launch probably by 2018-end or early-2019. The cost of this vehicle will get drastically reduced by one-tenth of the manufacturing cost of a normal PSLV. However, this rocket will have the total payload capacity of 500 to 700 kg and can launch satellites only up to the polar sun-synchronous orbit or near-earth orbit (500-700 km in altitude)."

India has a slew of satellites in the near-earth orbit that are used for the purpose of earth imaging, weather tracking and reconnaissance.

"The weight of this mini-PSLV will be just 100 tonnes as compared to 300 tonnes of the normal-sized launch vehicle," Dr Sivan said.

The "cost-effective" vehicle programme is in line with Isro chairman A S Kiran Kumar's recent statement that the space agency has been striving to "reduce the cost of access to space" and so that more and more of space technologies can be used for the benefit of the common man.

Explaining the advantage, Dr K Sivan said, "The amount of money used in building a normal-size PSLV rocket can actually be used to manufacture multiple numbers of such mini-PSLVs, which, in turn, can launch several satellites. So, Isro will be able to launch several satellites in less money." Like a normal PSLV, he said, "Such small vehicles will too be capable of launching multiple nano satellites."

Isro has started working on the idea of building this small rocket keeping in mind the emerging market of nano satellites. Till now, satellites of foreign customers are accommodated in launch vehicles only as secondary passengers. With Isro eyeing to capture the market of nano satellites, the small vehicle can be a boon for foreign satellite customers as the rocket can be readied in just three days on demand. On February 15 this year, Isro's workhorse PSLV C37 had launched 104 satellites, mostly of foreign customers, in one go. Likewise on June 23, the agency had launched 30 small satellites of foreign companies along with the primary satellite Cartosat-2.

So is this the PSLV-3S that was talked about years ago. Good to see they have been working on it. What ever happened to PSLV-HP that could put 2+ tonne satellite in orbit.

Surya and Sagarika have been thrown about for a while. I don't even know if they exist. But Agni-6 and K-4/5 will be ready soon enough.

Design for Small Satellite Launch Vehicle ready
ISRO hopes to launch it in six months.
ISRO’s Vikram Sarabhai Space Centre (VSSC) at Thumba here has completed the design for the Small Satellite Launch Vehicle (SSLV), the ‘baby rocket’ billed as the quickest way to space for small-size satellites. The SSLV promises on-demand access to space, with the rocket assembly taking a mere 15 days and minimum personnel to do it, VSSC officials said.
“The design is ready. We hope to launch the first SSLV in six months,” said S. Somanath, director of VSSC, ISRO’s lead centre for launch vehicles.
On the launchpad, the SSLV will stand 34 metres tall, 10 metres shorter than the Polar Satellite Launch Vehicle (PSLV) and around 15 metres shorter than the Mk-II version of the Geosynchronous Satellite Launch vehicle (GSLV). It is also a ‘thinner’ launch vehicle, possessing a diameter of just two metres.
With a lift-off mass of 120 tonnes, the SSLV can place a 500 kg payload at a height of 500 km in the Low Earth Orbit (LEO). The SSLV has three solid motor stages, and like the PSLV and GSLV, can accommodate multiple satellites, albeit smaller ones. Unlike the PSLV and GSLV, the SSLV can be assembled both vertically and horizontally.
It’s bigger siblings are assembled only in an upright position in the assembly bays at the Satish Dhawan Space Centre at Sriharikota. “In that respect, the SSLV is like the old SLV and ASLV which could be assembled flat on the ground,” a VSSC spokesperson said on Thursday. Ultimately, the SSLV is meant to cater to the commercial satellite launch market, said S. Rakesh, CMD of Antrix Corporation, ISRO’s commercial arm. The launch vehicle is expected to be a money spinner for the corporation, which will be jointly managing the rocket with ISRO.

Before we go on technical details and start news and updates, overview for starters:
sslv__1.jpg

Quick look:
SSLV or Small Satellite Launch Vehicle is a small lift launch vehicle for commercial and emergency launches.
Air launched and ship/submarine launched variants may emerge there in near future if demanded by navy and air force.

On a usual medium to heavy, expendable launch system, it takes from two weeks to 3 months to fabricate parts and assemble launch system on pad. In case of SSLV, we can do it in 2 days to 4 days within minimal manpower and can facilitate us 40-60 orbital launches per year.

The very purpose of creating a separate thread for SSLV is same.
  1. Will be used to launch microsatellites that will not be notable enough to have separate thread.
  2. Too many launches in a single year in future, we don't have to make a thread to cover every single launch. Sometimes, we may not even cover launch and just post statistics.
  3. To evaluate performance of Indian launch industry. As SSLV is a short cycle rocket and it's one launch can't be compared to that PSLV/GSLV/LVM3.
All further design & details of this system will be covered here but may be moved to make another dedicated thread for design if large range of variants emerge.

Strategic:
Besides India, there are only three countries (US, Russia and PRC) with active ASAT capabilities. Ability to shoot down enemy satellite doesn't work very well if enemy can do same to you. As putting a missile shield in space on satellite can't justify it's cost, it's better to possess ability to launch more satellites quickly into orbit.

US has Minotaur series of small rockets, Russia has Start-1 launch system, and China possess Kuiazhou 1 and 1A. India so will have SSLV and its variants.

Launch:
Will have a dedicated launch site called SSLC different from two existing launch pads (FLP and SLP) located in SDSC. Till new site is ready, FLP will be integrated with vehicle to facilitate at least demonstration launches to start operation and bag commercial orders.

First launch would have happened early this month immediately after GISAT-1 if coronavirus pandemic wouldn't have locked Indians in their homes.

Almost confused it for a ICBM missile there.

@Indx TechStyle are they talking about the same rocket here.

Spaceflight gets first crack at India’s new SSLV rocket – and puts up a ‘sold out’ sign

Globe Space, yeah know about that. Not sure what would be there financial situation now, whether to go ahead or put deal on hold.

This launch is supposed in second half of this year BTW.

Pre booking is not something I've ever heard of specially before when the Rocket isn't even assembled.

Anyways.
