ISRO General News and Updates

[Akask kumar]

Well, if talking of funds, our economy is also rocketed like GSLV 3.
Your idea of harbour is awesome but I'm in the favour of thinking again in signing MoU with a party which has upper hand on us such technology i.e. NASA. They will be dictating what we should do in that case.
If there's no necessity to do it immediately, I'm ready to wait.

i am not talking about collaboration.. i am talking of exchange of scientific data.. for instance..

for example ISRO and NASA will share their scientific data with their MOM and maven mission . similarly if we target europa(jupiter moon) and ask NASA for jupiter science data in exchange of europa data.they will agree.to this deal. coz no one has sent a probe to europa so far..and why to do and repeat the same NASA jupiter mission?? we are not in race with them..

 

[MKM]

But station around Jupiter will be way -way ahead in future.may be in 100 years. I think we should restrict our funds and effort within mars or up to asteroid belt... explore and mine the moon,mars,asteroid and explore venus plus a space station of our own should be the goals..later we can push boundaries.

even APJ kalam said that moon-mars-earth will serve as future space industry hub.

But if ISRO is hell bent on scientific exploration of deep space ,,they should target EUROPA instead of Jupiters .. Europa is complete water and ice and holds the key to deep space base establishment in far-far future..plus it may harbor aquatic life.. as far as Jupiter is concerned we can sign some MOU with NASA to share science data..

I think near earth objects & the sun must be our priority before Jupiter & other big projects.
For big projects, we should collaborate with NASA, ESA & JAXA like James Webb Space Telescope, Thirty-meter telescope, CERN projects.
I don't think democracies will have problem in sharing technology for future like Korea, Oz, US, Canada & Europe which will have technology of future.
Ultimately, in the future world is going to be integrated day by day except China, if more Trump won't born, even Indian public is too much positive on collaboration.
Hoping terrorism won't create further problem than today.
Russia has technology which we still don't have.
Before searching He-3 on the moon, near-earth asteroid for mining can be the idea...
As asteroids may have more He-3 than the moon.

This is a high time ISRO should replace this bulky PSLV with light weight small, cryo kerosene powerd small vehicle. PSLV is too out dated and a replacement is needed urgently.

ULV- a semicryogenic rocket using L-kerosense and LOX is under study .. this will replace PSLV,GSLV-1,2,3 series.. one rocket for all purpose from light to medium load..and for heavy load we will have HLV

asteroid is not very near to the earth ,FYI. asteroid belt lies beyond mars.. its between MArs and jupiter.. without mastering mining on the moon and having a station over earth, on moon and mars .. mining asteroid will be very difficult and costly..

We should not chase the NASA dream as we are not in race with them.. we have our own priorities.. as far as collaboration is concerned , it will happen in future more and more ..It doesnt matter how rich or how technoligically advanced are you,,Space dwarfs everything.. we should collaborate not on all but on certain difficult projects ..

Ayush ministry & ISRO to launch Tele-Ayush Project to take healthcare in remote areas

The Union Ministry of Ayush and the Indian Space Research Organisation (ISRO) will soon launch a collaborative project 'Telemedicine in Ayush (Tele-Ayush) Project' for taking the excellent healthcare facilities to the people living in the poorest and remotest areas of the country, where conventional methods of transport and help usually fail to work.

This joint effort will make it possible for doctors and healthcare professionals to save many lives in areas where basic life sustenance is a daily problem. Precious lives are needlessly lost just because there was no doctor at hand when the situation required. The Tele-Ayush project aims at providing feasible healthcare services to the neediest beneficiaries in the country, making the best use of satellite technology, which will be provided by ISRO.

The Ayush Ministry's initiative in this regard is significant as healthcare in India has always been a major issue to tackle, chiefly due to the sheer scale of the numbers. India's mammoth population, coupled with the vast and varied terrain, which separates the rural and urban areas and the lack of basic, adequate facilities in rural and remote areas has made it a gargantuan task to provide quality and efficient healthcare to the people residing in such areas. While their urban brethren continue to enjoy the choicest medical care and attention, India's poor and underprivileged do not have access to basic life necessities, let alone healthcare. Keeping this in mind, the Ministry of Ayush and ISRO have come together to launch this collaborative project.

Earlier, the Ministry had constituted a Working Group, under the chairmanship of Dr. R. K. Manchanda, DG, Central Council for Research in Homoeopathy, for the development and propagation of Tele-Ayush. The Working Group was asked to deliberate on specific points and submit a report. These points include gather the detailed requirements from the Ministry of Ayush; gather information on the technicalities of implementation; a detailed budgetary analysis for the entire project; ascertain resource requirement (human, hardware/software, infrastructure, etc.); a feasible time-line for development and deployment; and a thorough analysis and study of the entire project.

In its report submitted to the government recently, the Working Group recommended that the Ministry can utilize the existing infrastructure (dispensaries etc.) for providing healthcare services in remote and rural areas; Tele-Ayush can also utilise the ISRO's existing telemedicine nodes located across country; CHCs and PHCs can be strengthened and developed by providing the services and expertise of Ayush doctors; these can also be used as specialized centres for providing exclusive healthcare services to people; Ayush doctors/paramedics can be further trained by CME programmes conducted through the TM network; they can act as consultants at the PHCs and CHCs as required and provide valuable help to the already practising doctors and healthcare personnel; smaller research units of the Councils, or Ayushgrams, can be implemented in rural/tribal areas which can function as nodes for the public outreach programmes with the provision and deployment of adequate manpower; and National/All India Institutes and Central/Regional Institutes of Research Councils of Ayush systems can also operate as nodes for specialized consultations.

On the role of the Ministry of Ayush, the Working Group recommended to Identify super specialist nodes (SS Nodes) & patient nodes for providing telemedicine consultation services by the Ministry; Preparation of TM consultations weekly schedule well in advance and to be sent to all concerned, like doctor end nodes, patient nodes, TM hub at ISTRAC Bengaluru and DECU/ISRO; Monitor and send monthly network utilisation report to DECU/ISRO; Arrange maintenance of civil, electrical and other supporting infrastructures at the user location; Arrange safe custody of items supplied and installed, identification of the custodian for each TM node and maintain the inventory which should be verified periodically; Arrange lodging complaint with local police in case of theft/loss of any item and to send one copy of FIR to DECU/ISRO; Enter into separate MoUs between themselves and the user agencies where TM nodes are to be installed for operations, safekeeping, maintenance payments after one year of phase-1 etc; Identifying local dedicated site coordinators at the telemedicine centres for enabling smooth setup of facilities; The selected centres to provide required civil infrastructure like room (10' x20'), space for antenna, power, UPS, furniture, etc; and Providing manpower support for the smooth operation of the telemedicine nodes and identification of the doctors/medical staff for supporting teleconsultations, both at the patient nodes and selected super specialist nodes.

TBH, I don't think even mining on the moon will be possible but we should spend like ₹1000 crore every year on outer space research, that motivates people.
See countries where people are becoming terrorist & scientists.
Anyone choose a path, a good number of people will follow him/her, no matter what path he/she choose.
I don't think spending ₹1000 crore on space research will pull us into poverty but surely it will pull us into a new world of science where everyone would be wanted to become Kalam or Raman.
I think you miss interpreted my message.
Read it again.

See Near-Earth Objects
I said not India but the whole world should think about it(just an idea), well I'm not expert but I thought When NEO asteroids go near to the sun they get a good amount of He-3.
He-3 on the moon also is due to solar wind & you know when comets & asteroids go near to the sun obviously they get more He-3.
I didn't say we are in race with NASA, I said we must collaborate as the world is going closer day by day hoping Trump & terrorism won't create problems for nations to come closer & collaborate with each other.(or say democracies)

ISRO postpones scramjet mission

THIRUVANANTHAPURAM: The Indian Space Research Organisation (ISRO) has put off the scramjet propulsion mission slated from Sriharikota on Thursday on account of the ongoing search for the Air Force’s AN-32 aircraft which disappeared over the Bay of Bengal.

ISRO officials said the military had requested that the mission be put off. Dr K Sivan, director, Vikram Sarabhai Space Centre (VSSC), Thumba, termed the disappearance of the aircraft a national calamity and said the search took precedence over the experimental mission. “We have not decided on a new date,’’ he said, after a Mission Readiness Review (MRR) on Monday. The AN-32 aircraft, which took off from the Tambaram airbase in Tamil Nadu on Friday with 29 persons aboard, had gone off the radar on its way to Port Blair. A frantic search has since been launched for the missing aircraft.

ISRO is readying for its first experiment to try out scramjet propulsion - or air-breathing propulsion - whose successful development would result in smaller, compact launch vehicles with higher payload capacity.

Scramjet propulsion will allow ISRO to avoid carrying oxidisers aboard its rockets. Oxidisers help fuel burn in a rocket. For instance, in its second stage, the Polar Satellite Launch Vehicle (PSLV) uses N2O4 or nitrogen tetroxide as the oxidiser and Unsymmetrical dimethylhydrazine (UDMH) as fuel. In scramjet propulsion, the rocket gathers the required oxygen from the atmosphere during flight. For the mission, Vikram Sarabhai Space Centre has built ISRO’s biggest sounding rocket to date. The Air-Breathing Propulsion Project and the Advanced Technology Vehicle project at the Vikram Sarabhai Space Centre are responsible for the development of the mission.

Though, I'm also in favour of caring life of 29 people than firing rockets, I still hope it doesn't affect GSLV Mk2 launch schedule in August.

ISRO's Participation in Antarctic Expedition

The National Centre for Antarctic and Ocean Research (NCAOR), Ministry of Earth Sciences, Government of India, organises the Indian Scientific Mission to Antarctica every year and ISRO has been participating in it for a long time. This year, in the 35th Indian scientific expedition, ISRO participated with three projects - one on-going project from Space Application Centre (SAC) and two new projects from National Remote Sensing Centre (NRSC). During the expedition, the project team collected ground data to interpret and validate the satellite images and also installed instruments for the measurement of green-house gases and atmospheric black carbon during Austral summer (November 2015-March 2016).

Antarctica ice sheets play an important role in influencing the climate system. Global climate change has a great impact on the ice shelves because they are sensitive to changes in air and ocean temperature or circulation near Antarctica. Extensive work on this has been done in the past by ISRO scientists; the latest studies during the 35th Indian scientific expedition are described below

• SAC collected ground observations near Bharati and Maitri stations using indigenously developed Ground Penetrating Radar (GPR) of 500 MHz. GPR data was collected at seventeen locations on Ice Sheet, Ice Shelf, Iceberg and Sea Ice etc. GPR penetrated through almost the entire observed thickness of Sea Ice, found to be around 2 meters, which is consistent with the field. The GPR data could also provide the thickness of top stratigraphic layers over Ice Shelves, Icebergs and Ice Sheets.

• SAC/ISRO is also providing near real time Sea Ice advisory to NCAOR since 2012, using data from Indian satellites, namely, RISAT, Resourcesat-2, AWiFS, LISS-III, LISS-IV, Saral-Altika and foreign satellite data and products. This helps in safer ship navigation through Sea Ice portion of Antarctica.

• Towards the measurement of atmospheric Black Carbon (BC), Green House Gases and Solar Radiation Fluxes at Antarctica on a long term basis, NRSC has installed Atmospheric CO2Sensor at Bharati station and also measured total Ozone during ship voyage.

• NRSC also participated to Study the snow melt/freeze dynamics in Antarctica and Sea Ice characterisation using space based and ground based observations. To understand melt/freeze dynamics and its response to microwave remote sensing data, snow properties were collected using GPR (200 MHz and 400 MHz) and Snow Fork (Density and Wetness) near Bharati and Maitri Stations. GPR profiles were collected on 5 routes over ocean to measure Sea Ice thickness and on 10 locations over Sheet Ice.

• Snow density and wetness observations using snow fork were collected on 13 days and 20 pits were dug with a maximum snow depth of 1.2 m..

• Spatio-temporal dynamics of surface melting over Antarctica using scatterometer data from OSCAT on-board Oceansat-2 and QuikSCAT are available under NICES programme on Bhuvan portal

How these rockets with scramjet will work when in space ? Will it collect oxygen for that also ? If successful , will it be a single stage job to place satellites ?

They will be carried by scramjets till orbit.
In space, they can use ion propulsion for a small distance. As far as exploration spacecrafts are concerned, let ISRO test it's radioisotopes on Chandrayaan 3 and 4.

So that mean placing satellites will not be a single stage job . It will be a multistage mission .

ISRO don't has ion propulsion engines .

ISROs scramjet engine will also be able to liquefy and store oxygen onboard .
So I think that can be used for space propulsion .

In literal meaning sending (satellite to GTO) is single stage. Satellite always has own thrusters to place itself in the orbit and there are nearly 3-4 orbit raisings. It's not called stage, nor it can be carried out by rocket.
We have to place satellite between 35500 to 36000 km height. Such a precision is given by thrusters.

Your idea is good.
But
For ion propulsion, ISRO has been developing it. We could have deployed it earlier too on GSAT-4 if launch malfunction would not have occurred.

same here .. the search and rescue should be our priority.But this also highlight the shortage of manpower ISRO is facing.. coz search and rescue is shared by navy & airforce also ,its not like that ISRO is solely doing the search operation..this operation should not have affected the experimental launch..

or may be the scramjet is not ready yet and ISRO is using this rescue as cover..

No , I don't think so . It can't be the case of manpower . For search and rescue they don't require scientists of scramjet program , and these scientists also will not divert there mind from there project to search and rescue . They have separate teams of experts for searching .

But the case can be of the availability of required satellite . Satellites which are required to moniter scramjet testing should have been diverted for search and rescue mission .
This can be the most probable and suitable reason for delay .

Or I think it's emotional.
ISRO has already carried out search for debris of plane but could not find it.
So, if plane sunk in sea was without getting broken, it gonna take a week at least to get it on surface. Probability of getting anyone alive is very low.
Though, I don't wanna say this and wishing that they're alright, I fear that rescue operation has changed into a search operation.

Loss of 29 soldiers is very significant.
It is enough reason for us to not carry out any prideful mission in such grief.

NOT NOw the RLV will be a TSTO -- two stage to orbit.. the first stage will push the satellite(2nd stage) beyond the atmosphere at certain height from there the first stage will detach and glide back to the run way.. at that height i believe a semicryogenic engine will be used to place the satellite of the second stage in desired orbit.. the second stage after placing the sat will also land using parachute.

what you said about liquifying the atmospheric oxygen to be used in space as oxidiser will be used in SSTO(singel stage to orbit) which will be developed after we master the TSTO..i think the SSTO is project named as AVATAR.
