Thiruvananthapuram:

The Gaganyaan manned space flight mission will launch “Indian astronauts into space from Indian soil on an India-made rocket”, Dr Unnikrishnan Nair, the head of the elite Vikram Sarabhai Space Center in Kerala’s Thiruvananthapuram, told NDTV in a special interview this week.

Expected to cost Rs 9,000 crore, Gaganyaan is a “national mission” that will send four specially chosen and trained male test pilots from the Indian Air Force into space, Dr Nair said.

In an exclusive tour of the country’s main rocket lab, an ultra-secure facility, NDTV was given glimpses of the crew module – in which the four pilot-astronauts will travel into space – and the service module – which will be attached to the former, and the space suits that they will wear.

The crew module, Dr Nair said, is a little over 10 feet in diameter and is configured for three people, but this can be adjusted depending on mission requirements. The space suits were purchased from the Russians as part of a deal to buy the seats, which follow the ‘cradle’ philosophy, he said.

On the test pilots themselves, Dr Nair said, “You know… since they are from the Air Force, they are close to astronauts in terms of key attributes, like quick response time, and have responded well to tests like centrifuge, which subjects them to higher acceleration forces.”

“They are now an astronaut training centre for 13 months for training on survivability in different conditions, and then will be subject to parabolic flight tests. Then they will go to Bengaluru, where a Human Space Flight Centre is set up and will get more training, including physical training.”

The four pilot-astronauts – dubbed ‘India’s Fantastic 4’ – were revealed to the country by Prime Minister Narendra Modi last week; they are Group Captain Prasanth Balakrishnan Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap and Wing Commander Shubhanshu Shukla.

Their training will also include academic courses and detailed instruction on Gaganyaan flight systems, as well as yoga, sources at ISRO, India’s space agency, told NDTV.

Earlier all four also received training at Russia’s Gagarin Cosmonaut Training Centre.

Dr Nair also explained why no women will be part of this historic space flight – because pilot-astronauts are drawn from the ranks of Air Force test pilots. At the time, India has no women in that role.

“When I was HSFC (Human Space Flight Centre) Director, we put this idea to the Air Force. But unfortunately, there were then no women test then. Now, I understand there are women test pilots and I hope they will soon join us,” he said.

Meanwhile, NDTV also met Vyommitra – the robotic (female) humanoid that will fly into space for a test flight ahead of the mission. The launch of Vyommitra – whose name comes from Sanskrit words meaning ‘space’ (‘vyom‘) and ‘friend’ (‘mitra‘) – may be in the third quarter of this year.

Overall, work is on at full pace for the Gaganyaan mission, which will cost about Rs 9,000 crore, with the four test pilots undergoing special training and the launch vehicle now humanrated, which means its ability to safely carry and return its human occupants has been evaluated and confirmed.

Before the manned flight, though, there must be at least two successful unmanned flights, the first of which, if all goes well, will take place by the middle of, or end of, this year, NDTV was told.

New Delhi:

Indian space agency ISRO today put its first test flight for its human spaceflight mission ‘Gaganyaan’ “on hold” 5 seconds from its scheduled launch time at 8:45 am IST.

“The test vehicle lift-off for the Gaganyaan mission could not happen,” ISRO chief S Somanath said minutes after the on-board computer aborted the lift-off of the rocket.

Today’s test flight was meant to carry various crew safety related payloads and conduct its necessary mission objectives as part of the first test in a series of tests scheduled by ISRO before the main mission taking Indian astronauts to space likely by the end of 2024.

The countdown began as intended and all went as expected till T-6 seconds when the rocket ignition kick-started six seconds before its intended lift-off schedule. Looking at this anomaly, the on-board computer immediately overrode the lift-off at T-5 seconds and put the mission “on hold”.

“The engine ignition has not happened in the nominal course,” ISRO chief S Somnath said in his statement following the incident, adding that “We have to find out what went wrong, will come back soon.”

“There was a very smooth air lift and automatic launch sequence leading up to the command to lift off, but the engine ignition has not happened in the nominal course due to anomaly,” Mr Somanath said.

Mr Somnath mentioned that the “vehicle is completely safe”. He also said that ISRO will “come back soon after analysing what triggered the Automatic Launch Sequence (ALS) holding the vehicle.”

“We will have to reach the vehicle and then look at what has happened now,” Mr Somnath explained, adding that this process “takes some time”. However, ISRO shared an update soon after saying that the launch will happen at 10 am IST.

Earlier today, the test flight, which was originally scheduled for 0800 hrs (8 am IST) was rescheduled to 8:30 am and then again to 8:45 am IST “due to local weather conditions”.
