Mission Gaganyaan: ISRO to launch first development flight of test vehicle on Oct 21 morning
Bengaluru (PTI): ISRO on Monday said it would commence unmanned flight tests for the Gaganyaan human spaceflight mission with the launch of a test vehicle between 7 am and 9 am on October 21 from Sriharikota spaceport to demonstrate the performance of the crew escape system.
In a message on social media platform X, the national space agency headquartered here, said, "Mission Gaganyaan: The TV-D1 test flight is scheduled for October 21, 2023 between 7 am and 9 am from SDSC-SHAR, Sriharikota."
ISRO Chairman S Somanath on Saturday told reporters three more test vehicle missions would be launched under the Gaganyaan programme after the TV-D1 test flight on October 21.
The Gaganyaan project envisages a demonstration of ISRO's human spaceflight capability by launching a human crew to an orbit of 400 km and bringing them safely back to earth by landing in Indian sea waters.
The Test Vehicle Development Flight (TV-D1) is aimed at testing the crew module (CM) that will carry Indian astronauts during the human spaceflight late next year.
The TV-D1 test flight involves launching the unmanned crew module to outer space, bringing it back to earth and recovering it after touchdown in the Bay of Bengal.
"The first test vehicle flight (of the Gaganyaan mission) will be conducted on October 21. After that, we have planned for three more test missions, D2, D3, D4. We will hold thorough tests during the test flight sequence," Somanath, who is also the secretary, Department of Space, had told reporters in Rameswaram.
According to ISRO, the test vehicle is a single-stage liquid rocket developed for this abort mission. The payloads consist of the Crew Module (CM) and Crew Escape System (CES) with their fast-acting solid motors, along with CM fairing (CMF) and Interface Adapters.
"The Crew Escape System with Crew Module will be separated from the Test Vehicle at an altitude of about 17 km. Subsequently, the abort sequence will be executed autonomously commencing with the separation of the CES and deployment of the series of parachutes, finally culminating in the safe touchdown of CM in the sea, about 10 km from the coast of Sriharikota," ISRO said.
The crew module is where the astronauts will be contained in a pressurised Earth-like atmospheric condition during the Gaganyaan mission. The CM for the Gaganyaan mission is under different stages of development.
For the TV-D1, the CM is an unpressurised version that has completed its integration and testing.
"With its complete set of parachutes, recovery aids actuation systems and pyros (pyrotechnic device used to separate spacecraft from rocket), the avionics systems in CM are in a dual redundant mode configuration for navigation, sequencing, telemetry, instrumentation and power. The CM in this mission is extensively instrumented to capture the flight data for evaluation of the performance of various systems," it said.
The crew module will be recovered after touchdown in the Bay of Bengal, using a dedicated vessel and diving team from the Indian Navy.

BJD govt will expire on June 4: PM Modi in Odisha
Berhampur (Odisha) (PTI): Prime Minister Narendra Modi on Monday asserted that the expiry date of the BJD government in Odisha is June 4, the day the assembly election results will be announced.
Addressing his first election rally in the state, Modi urged people to give a chance to the BJP to make Odisha the number one state in the country.
In an apparent dig at BJD president and Chief Minister Naveen Patnaik, the prime minister said, "Odisha needs a CM who understands Odia language and culture."
"The BJP will form a double-engine government here after elections. The expiry date of the BJD government is June 4, 2024," Modi said at the Berhampur rally.
He also claimed that Odisha has not benefitted from Ayushman Bharat Yojana as the "BJD government did not implement" it in the state.
The Centre gave Rs 10,000 crore under the 'Jal Jeevan Mission' scheme to Odisha but the BJD dispensation could not spend the money properly.
"You have given 50 years to Congress and 25 years to BJD. Just give five years to the BJP. We will make Odisha the number one state in the country," Modi said at the rally.
Odisha has fertile land, mineral resources, and sea coasts, but people are still poor, he claimed.
"We released a visionary manifesto for Odisha promising jobs for youths and women and health facilities for senior citizens. BJP fulfils what it says: Modi added.
The assembly and Lok Sabha elections in Odisha will be held simultaneously.
"I have come here to invite you to the swearing-in ceremony of BJP's CM on June 10. On the very day, we will implement the Ayushman Bharat-Pradhan Mantri Jan Arogya Yojana which the Naveen Patnaik government has been resisting. This son of Lord Jagannath will take care of all senior citizens under this scheme," Modi said.
Referring to Patnaik's alleged weak command over Odia language, Modi said: "A person, who lives, understands and takes pride in Odia culture and tradition, can help resolve the problems of Odisha at a faster pace...".
He appealed to the people to allow BJP to serve the state for once and it is Modi's guarantee that Odisha will be turned into the number one state in the next five years.
The prime minister said Odisha lags behind in every development parameter despite having huge resources like water, fertile land, rich mineral wealth, and a vast coastline.
"Who is responsible for Odisha’s backwardness? Why are the people of resources-rich Odisha still poor? The answer is rampant loot by Congress, which ruled the state for 50 years, and then the BJD for next 25 years. The BJD is sinking, while Congress is a spent force and the BJP is the only ray of hope for the people," he said.
The prime minister also said that the BJP has given the country's highest post to the daughter of Odisha. "It is my good fortune that President Droupadi Murmu Ji tells me every minute for the development of Odisha. I feel that I will be able to do a lot for the state under her guidance," he said.
Responding to Modi's claim, senior BJD leader and Naveen Patnaik's close aide VK Pandian said: "Naveen Patnaik will take oath as the chief minister of Odisha for the sixth consecutive time between 11.30 am to 1.30 pm on June 9."
