From the future plans chart - Scatsat-1. Seriously?

Why ? it is the one badly needed by all. Wind speeds over oceans is another critical parameter for other observations, not to mention shipping and marine needs. The idea of separating it on a separate sat unlike clubbing it with other payloads on Oceansat makes sense.

Actually there is something called C-60 as a follow on to the current C-25. Also a C-100 was proposed as well. Ofcourse this C-100 was meant for HLV with 100t to LEO

I am not sure what the designation given to the 600KN Cryo engine which is currently under development and was allocated 700 crore for 11th plan period.

Bade,

The comment related to the satellite's name, not the satellite itself.

vasu raya · Post by **vasu raya** » 08 Jun 2012 09:16

usually setting up of wind energy parks requires a lot of study of ideal locations for consistent wind speeds, trying to determine the sites using ground based sensors for wind speed sampling might get expensive and time consuming, can the scatsat make an impact here? or is it only useful for macro level studies?

Oh I see

Well you know the Amreekis have been calling the Scatterometer on board Oceansat-2, OSCAT sounds like the supplements one take OSCAL, since ISRO forgot to give it a proper name. The other payload is called OCM. So this time around they wanted a proper name, but still could not find one.

As an anecdote, I am told when Amerikis gave the name Quickscat to their now defunct scatterometer, the reason was that it was quick fire replacement at short notice for another failed mission/payload, hence the word "quick" a very unnatural name.

Bade · Post by **Bade** » 08 Jun 2012 23:46

Over land no, since wind speed is measured as an indirect measurement from sea surface roughness as seen by the scatterometer.

danke Bade saab, now a days coastal wind farms are a rage,
far enough from the coast that they are out of sight of beach goers,

in the Indian context, with no real estate acqusition issues,
a very large coastline
with wind speed calibration from the scatsat
marine qualified turbine components and composite blades technology from DRDO
an Indian version of Suzlon energy should be in business

would agree to disagree on the priorities part, we are a energy deficit country; space applications should be ok on this thread.

What is the space application of this? Wouldn't a company investing in a wind farm want to get local measurements rather than rely on satellite based estimates?

I would think the satellite data would be useful for identifying locations with a strong potential for development but development would only commence after long-term local measurement. I'm happy to be corrected about this.

Suraj · Post by **Suraj** » 09 Jun 2012 07:09

The discussions on wind power suggest India isn't doing anything in the field. On the contrary we've the 5th largest installed capacity and the 3rd highest annual capacity addition rate, behind PRC and USA, and ahead of all the Euro countries, whom we'll soon overtake in installed capacity at current rate of addition. Investment in windpower will be driven by cost of the energy; in an economy partial to the cheapest source of power, money will go into cheap hydrocarbon sources before wind.

vasu raya · Post by **vasu raya** » 09 Jun 2012 08:54

Pratik & Suraj, between the capability of the current scatterometer and say a latter follow on that can detect the subtle surface wake of a shallow submerged sub, the case for local measurements for wind speeds can be made, at least in theory and a sat is ideal for repeated measurements over a time period

to become cost competitive, consider the per tower capacity, a higher capacity wind turbine for the same installation cost reduces per unit price and for such large turbines, sea locations without any obstructions are found to be ideal. KMGT is rated between 12-15MW, why not produce a wind turbine at that scale?

again, wind energy ROI is sensitive to the local measurements and the Indian coastine is vast, so sats may have a role to significantly reduce the lead time for wind parks

and at this point we are not even bringing in carbon tax

alexis · Post by **alexis** » 12 Jun 2012 19:17

Offshore wind farms are unlikely to be viable in India in the near future due to their high cost compared to land based ones. Also, nobody manufactures/assembles offshore turbines in India; hence costs are likely to remain high.

A question to Aerodynamics Dadas of BRF.

Advantage of liquid stage is said to be that it can be on-off-on-off at will, whereas Solid engine, once ignited, will burn till it has exhausted masala. ( That is my conception .. may be wrong ).

Question is : In that case how does one ensure that the solid stage is fully burnt at the exact moment that it is discarded? Or is it so that the stage is still burning when it is discarded?

But if it is still burning then how will it separate because its thrust is still pushing it against the next stage?

symontk · Post by **symontk** » 19 Jun 2012 18:39

Pressure sensors will tell whether the stage is fully burnt or not. there are retro rockets to push back the solid stage. But in case of GSLVMK3, it will fly away from the main vehicle while burning, so that the main vehicle is safe

ISRO mulling hiving off satellite production to industry- PTI

New Delhi, Jun 24 (PTI) As it prepares for Moon and Mars missions, ISRO is planning to hive off production of communication satellites and polar satellite launch vehicles (PSLV) to the industry.

The space agency is keen to focus on unique science projects, develop remote sensing satellites and do more R&D instead of engaging in the repetitive exercise of building communication satellites and launch vehicles.

http://en.wikipedia.org/wiki/SpaceX#Funding

As of May 2012, SpaceX has operated on total funding of approximately one billion dollars in its first ten years of operation. Of this, private equity has provided about $200M, with Musk investing approximately $100M and other investors having put in about $100M. The remainder has come from progress payments on long-term launch contracts and development contracts. NASA has put in about $400-500M of this amount, with most of that as progress payments on launch contracts. SpaceX currently has contracts for 40 launch missions, and each of those contracts provide down payments at contract signing, plus many are paying progress payments as launch vehicle components are built in advance of mission launch, driven in part by US accounting rules for recognizing long-term revenue.

Someone recently posted an article written in a British publication, about the alleged "race" to Mars between India and China. The article stated that India and Russia were together racing China to see who reaches the red planet first.

But India's Mars mission has no Russian participation; it is in the next moon mission, Chandrayaan-2, where the lander will be built by the Russians. Once again, is it any wonder that a British source would try some mischievous or dishonourable tactic to slight India's space efforts i.e bring a foreign country in, when they don't figure in the mission?

India Bolsters National Space Program Using NVIDIA GPU-Accelerated Supercomputer

NVIDIA today announced that the SAGA system, India's most powerful supercomputer(1) and the holder of the 85 position on the Top500 list released yesterday, is leveraging NVIDIA™ GPUs to dramatically improve the design and analysis of the delivery vehicles critical to the nation's space program.

Developed by the Indian Space Research Organization (ISRO), one of the six largest space research agencies in the world, the SAGA supercomputer is used to tackle complex aeronautical problems. Harnessing the power of 640 NVIDIA Tesla™ GPUs and providing up to 394 teraflops of peak performance, SAGA enables ISRO to accelerate and improve the design and analysis of new and existing satellite launch vehicles by enabling more complex and accurate design simulations.

With plans for 60 missions over the next five years, ISRO will develop a third launchpad at its spaceport at Sriharikota in Andhra Pradesh to meet the growing demand.

"We are planning to have a third launchpad at Sriharikota to cater to our future missions," Indian Space Research Organisation (ISRO) Chairman K. Radhakrishnan told the media.

He said the new launchpad would help ISRO augment the frequency of missions, which was necessary to meet its ambitious targets.

"We plan to launch 24 missions over the next 24 months, which include our communication satellites and some foreign payloads," he said, adding that over a five year period, the space agency has plans to launch 60 missions.

The new pad could also be used for launching Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk-III) carrying heavier satellites as also by the reusable launch vehicle, India's own version of a space shuttle.

It would include construction of a new vehicle assembly building, mobile pedestals, umbilical towers, emergency exits, ground escape system, crew ingress and egress systems, safety bunkers, material handling equipment and related electrical systems.

It is also part of ISRO's plan is to develop dedicated 'Space Park' next to the space port at Sriharikota. The new missions are necessary as there have been demands in the international market for ISRO's Polar Satellite Launch Vehicle to launch foreign satellites.

As ISRO starts building a launch vehicle for its mission, a launchpad gets blocked for nearly two months till the launch of a satellite.

With ISRO setting a target of 24 missions in 24 months, more launchpads become a necessity.

Besides communications satellites, ISRO also has plans to launch Chandrayaan-II, the sequel to its successful moon mission, launch a satellite to study the Sun, send a probe to Mars and undertake a human spaceflight.

On plans for developing another space port, Radhakrishnan said it was only at the stage of a feasibility study.

ISRO to build 3rd Space Launch Site

60 Missions means 60 Launches or 60 Satellites?

India is all set to give the go-ahead for an ambitious mission to Mars, expected in November next year.

“A lot of studies have been done on the possible mission to Mars”, Secretary in the Department of Space and Chairman of Indian Space Research Organisation K Radhakrishnan told reporters here.

“We have come to the last phase of approvals”, he said. .

“And I am sure that, maybe soon, we will be hearing an announcement on the Mars mission“.

According to ISRO officials, a significant amount of work on the planned Mars mission has been completed and scientific payloads have been short-listed.

The project report for Indian Mars Orbiter mission has been submitted for government approval.

The mission envisages launching an Orbiter around Mars using Polar Satellite Launch Vehicle (PSLV-XL). The Orbiter will be placed in an orbit of 500 x 80,000 km around MARS and will have a provision to carry nearly 25 kg of scientific payloads on-board.

The tentative scientific objective for the Mars mission will be to focus on life, climate, geology, origin, evolution and sustainability of life on the planet,” according to ISRO.

Scientific payloads have been short-listed by ISRO’s Advisory Committee for Space Sciences (ADCOS) review committee.

Baseline, solar array and reflector configuration of the satellite have been finalised, the Bangalore-headquartered space agency said.

10 petaFLOPS is the target set by C-MMACS. Had issued an EoI this February.

perhaps a year or two would be required to get a petaFLOPS facility
