India’s manned space mission, not in near future … or never?
By Nirad MudurNirad Mudur, Bangalore Mirror Bureau | Dec 4, 2015, 04.00 AM IST

Even if Centre okayed it now, it would take many years for mission to materialise; Institute of Aerospace Medicine remains clueless about training facility for astronauts

Awaiting the Union government's nod but already facing other delay-inducing obstacles, the much-touted manned space mission of India will not take place in the near future - not in 2017 as was expected; not even by 2021 as reported recently. In fact, with the prolonged delays, there is a fair chance that the mission may not take off at all.

The humungous Rs 12,400 crore mission - which entails putting a two-astronaut crew into a low-Earth orbit for a week and returning them safely to Earth - is nowhere close to starting its astronaut selection and training exercise. And senior Indian Space Research Organisation (Isro) scientists are not yet convinced about the safety aspects of the launch and spacecraft to go ahead with the mission even if the Union cabinet were to give the go-ahead anytime now.

"Setting up the facility, equipping it with human centrifuge machines, zero-gravity simulators and a range of equipment needed for training astronauts would need time," a senior official from Institute of Aerospace Medicine (IAM), which is tasked with selecting and training Indian astronauts for the mission, told Bangalore Mirror, requesting anonymity.

To indicate how much time would be consumed in the selection-cum-training process in India, he cited the example of the US's National Aeronautics & Space Administration (NASA). NASA has called for applications from a fresh batch of aspiring astronauts for Mars One and International Space Station missions over two months from December 14 to mid-February. The list of selected candidates for NASA will be announced only in mid-2017. The training of astronauts would take a minimum of 18 months to two years. "And we are trying it out for the first time," he said.

While the mission's budget has not found its place in the 12th Five Year Plan (2012-2017) -as the Centre's nod is still awaited - the Human Space Flight (HSF) programme will be pushed to only after the 13th Five Year Plan (2017-2022).

But Isro is in no hurry, while the IAM - which will select and train four finally-chosen astronauts - remains in the dark over what has happened to the land in the north of Bengaluru to set up an exclusive astronaut training centre, an Isro-IAM collaboration.

"Also, we are not sure whether the astronauts will be from Indian Air Force (IAF) or Isro." He said it is crucial to know that because the training duration for IAF fighter pilots would be considerably shorter as they are already exposed to strenuous flight training unlike Isro candidates. "Besides IAF fighter pilots are physically and medically fitter to be astronauts," he said.

"As of now I don't think IAF is even involved in the mission," he said, adding that Isro had not kept IAM in the loop about the latest progress on the mission's preparations. IAM falls under IAF's jurisdiction. It is the only centre in India certified to select and train astronauts after NASA and Russian Space Agency-recognised IAM as the centre for medical evaluation of astronauts and to conduct life sciences experiments in space in India in 1989.

But Isro doesn't seem to be perturbed by the delays. "We are not even talking about it (the HSF programme)," said Isro's head of press and publicity division, DP Karnik. "As of now, the Human Space Flight programme is not a priority for us. It is not on our prime list. We are only focussing on developing critical technologies that would be required for the mission. We are in no hurry at all," he added.

According to the HSF project director Unnikrishnan Nair, ensuring a successful launch and safe return of the astronauts are the prime objectives and Isro will take no risks on that front.

Isro on December 18, 2014 successfully tested the experimental flight of the planned manned mission launcher, GSLV Mk-III. The 3,775-kg crew module Atmospheric Re-entry Experiment (CARE) separated from the upper stage of GSLV Mk-III at 126 km altitude and 600-odd kg crew module re-entered the atmosphere to safely land in the Bay of Bengal with parachutes almost 21 minutes after lift-off.

Although the test was a success, the 2010 back-to-back GSLV launch failures is making Isro scientists extra cautious, a senior Isro scientist said.

However, with the prolonged delays, the space scientists are also bracing for the mission not to take off at all, but are not saying so openly at present. They feel ultimately it may be preferred to send Indian astronauts on board US or Russian launchers for deep-space missions rather than send them on indigenous ones.

not in 2017 as was expected; not even by 2021 as reported recently.

It was expected in 2021 IF the $ 2 billion funding is approved .All preliminary activities are being completed in the meantime
 
SELECTION OF CONFIGURATION OF CREW MODULE

Studies conducted indicated that the aerodynamics of the Crew Module was primarily governed by its forward base diameter and the side wall angle. Therefore, a comparative study of four typical manned capsules, with varying base diameter and side wall angles, was undertaken to arrive at the baseline configuration. The final configuration was selected after a detailed examination of many attributes like aerodynamic characteristics, structural and thermal protection system mass, volume needed for crew and various subsystems, etc.

The objective of the HSP is to carry a crew of two to LEO and return them safely to a predefined destination on Earth.

The main features of the mission are:

  • Mission duration is a few hours for the first mission and extendable up to seven days.
  • Emergency mission abort and crew escape provision is provided.
  • CM has capability to manoeuvre in atmosphere along both down and cross ranges.
  • Deceleration/ acceleration is within 4 g considering crew comfort.
A National Committee was constituted by the Prime Minister’s Office in February 2009 with Shri Montek Singh Ahluwalia, Deputy Chairman, Planning Commission, as the Chairman, to examine the ‘desirability and need for HSP’.

The committee had a comprehensive look at the project report including the rationale, need, desirability, technological capability, progress made so far and the preparedness for implementation. The committee unanimously recommended that the project report submitted by the Department of Space (DOS) may be processed for further necessary sanctions so that the programme, which is a part of the approved eleventh Five-Year Plan, could be implemented without delay.

HUMAN-RATED LAUNCHER

ISRO’s next generation launch vehicle, LVM-3, is gaining momentum and the first experimental flight with passive cryo was a total success. The first development flight of LVM-3, with the indigenous cryo stage, is scheduled for 2016. LVM-3 has fewer numbers of stages and more payload capability than GSLV-Mk II. Moreover, with LVM-3 payload capability, long-duration human space flight with a habitat module can be configured in future. Human-rated LVM-3 is now identified as the launch vehicle for Indian HSP.

CRITICAL TECHNOLOGY DEVELOPMENT FOR HSP

It is generally felt that a programme of this magnitude is best implemented by executing in well-defined phases. In each phase, a select set of objectives are to be attempted and the successful demonstration of those objectives would take us closer to the final set goal of human space flight.

In the first phase of the programme, technology development of certain key areas was proposed. Crew Module systems will be developed and flight-tested using an unmanned flight. Crew Escape Systems (CES) will be realised and its performance will be demonstrated through a Pad Abort Test (PAT). This phase will be followed by the second phase in which thrust will be accorded for the setting up of facilities and infrastructure. CES qualification using test vehicle flights and integrated flight test of orbital vehicle and CES also is proposed to form part of this phase. These developmental efforts and flight tests will lead to the manned spaceflight using human-rated launch vehicle. An unmanned flight with the full complement of systems will precede this.

At present, the focus is on the following:

a) Development of new technologies required for HSP in the areas of

  • Crew Module systems including re-entry and recovery elements,
  • Environmental control and life support systems and flight suit, and
  • Crew escape system.
b) Undertaking unmanned flight testing of the Crew Module systems in LVM-3-X flight.

c) Demonstrating the performance of Crew Escape System through Pad Abort Tests.

d) Development of Environmental Control and Life Support System (ECLSS) and carrying out an integrated test of ECLSS with Crew Module on ground.

The successful completion of this phase of critical technology developments will enable ISRO to prove its capability leading to the full-fledged HSP.

CARE MISSION IN LVM-3-X FLIGHT

CARE (Crew Module Atmospheric Re-entry Experiment) mission was conceived as a platform for validating the aero-thermal performance of Crew Module along with the re-entry technologies and for confirming the performance of parachute-based deceleration system. In the experiment conducted on 18 December 2014, the Crew Module separated from the LVM-3-X at an altitude of 126 km, then re-entered Earth’s atmosphere, initially in closed-loop control and guidance and descended further in ballistic mode. During the exoatmospheric phase, three-axis control using the Reaction Control System (RCS) of the module ensured that rates were damped out and the CARE, on the payload Adaptor (PLA) of LVM-3,was held at proper re-entry attitude. Below 80 km, the Crew Module followed a ballistic re-entry trajectory. After the initial aero-braking phase, further deceleration of the module was achieved using parachute-based deceleration system.

The Crew Module made a safe landing in the Bay of Bengal at a location less than 5 nautical miles (or 9.26 km) away from the predicted impact point which was approximately 600 km away from Port Blair and 1,600 km away from the launch range in SDSC-SHAR. The Crew Module was then successfully recovered by the Indian Coast Guard (ICG) and brought back to the Ennore port, Tamil Nadu.

The total mass of CARE was 3,775 kg. All the crucial parameters such as the mass properties, the external geometry, the parachute system, including the pyro devices and the apex cover separation/jettisoning system, were all exactly the same as would be in the planned manned mission. In the ascent phase, CARE was mounted over LVM-3 Payload Adaptor (PLA).

CARE was a magnificent achievement of ISRO meeting all the envisaged objectives. With the successful completion of this mission, critical technologies for Crew Module including blunt-body re-entry aerodynamics, ablative thermal protection system, deceleration system, etc., were all validated.

CREW ESCAPE SYSTEM PAD ABORT TEST

Crew Escape System (CES) Pad Abort Test (PAT) is a rehearsal for a crew escape from launch pad in case of an exigency after crew ingress. In PAT the Crew Module will be propelled to an altitude and range of approximately 2 km, from where it will safely descend in parachutes for a touchdown in sea. The objective of PAT is to prove the concept of CES and to obtain an assessment on the configuration and performance of all the associated systems and subsystems.

ENVIRONMENTAL CONTROL AND LIFE SUPPORT SYSTEM (ECLSS) AND FLIGHT SUIT

In manned missions, Environmental Control and Life Support System (ECLSS) performs many critical functions, which are essential for supporting the life and ensuring the safety of the crew. ECLSS maintains the cabin pressure and air composition, removes carbon dioxide and other trace contaminants, controls the cabin temperature and humidity and supports the flight suit systems. Auxiliary requirements like fire detection and suppression, food and water management system and crew support in case of emergency are also part of the system. ECLSS maintains an Earth-like atmosphere inside the cabin during all phases of the flight. The crew will be wearing flight suit during ascent and descent phases of the flight as an additional safety measure to take care of any malfunctioning of cabin ECLSS. The flight suit alone can support the crew for about one to two hours.

The layout and preliminary design of ECLSS have been completed. Various critical components like air–liquid heat exchanger, liquid–liquid heat exchanger, space radiator and LiOH (lithium hydroxide)-based canisters have been realised and detailed characterisation tests are in progress. Many new technology development activities are initiated in different areas like high-emissivity–low-absorptivity coating, coolant line insulation, special biocompatible coolant with low freezing point, condensate collection system, etc.

Design and development of flight suit have also crossed many milestones and a few development models have been realised and tested to prove the concept.

It is proposed to integrate the ECLSS subsystems and carry out an integrated test with one of the CM models as part of the critical technology development.

HSP: FUTURE ROAD MAP

We are also contemplating on what should follow PAT. As part of critical technology development Crew Module, ECLSS and CES systems will be realised. Some of the systems such as the crew module have already gone through performance demonstration test in LVM-3-X/CARE mission of December 2014. The CES systems which are being realized will be exercised in Pad Abort Test. ECLSS components will go through ground-level integrated tests with Crew Module.

The manned version of Crew Module is a twin-walled structure with the internal shell made as a sealed, all-welded construction. Configuration studies and preliminary design have been completed for this version.

Performance of the CES will be demonstrated in PAT. But it is designed to function in different regimes of the ascent flight of the launch vehicle and needs to be tested in those flight conditions. It is normally done with the aid of test vehicle designed to take the CES through the specified test conditions.

Finally, the ECLSS in the integrated condition, after testing in ground facilities, needs to undergo a testing in an orbital vehicle simulating zero gravity and deep vacuum outside the module.

It is proposed to develop the orbital vehicle comprising Crew Module and Service Module and carry out a flight test inside the payload fairing in one of the future missions of GSLV-Mk II or LVM-3 vehicle. The test vehicle for Crew Escape System will be developed and the CES will be qualified for all critical in-flight conditions. After ground evaluation of ECLSS and flight suit, the whole system will be integrated and flight-tested as part of an orbiting vehicle.

Human space flight is a challenging techno-managerial activity that calls for synergized efforts of a number of national institutions, academia and industries in the country with ISRO playing the lead role.


That 'original' plan was for a much smaller Crew module,for two astronauts to be launched on gslv mk2

Wordcraft will ensure it gets labelled an indigenous attempt.

Go troll elsewhere,false flagger

Are you dumb? Read post no4

'Indian' has not even started project yet....:lol:
