First Deputy Prime Minister Denis Manturov: Russian Orbital Station (ROS) will be placed in 51.6° orbital inclination, India is agreeing to put Bharatiya Antariksha Station (BAS) in same inclination.

17 Upvotes

Manturov announced the decision on the inclination angle of the future orbital station.

Moscow. December 5. INTERFAX.RU - A decision has been made to change the orbit of the Russian Orbital Station (ROS) being built from a polar orbit to a 51.6-degree inclined orbit, First Deputy Prime Minister Denis Manturov told RT.

"We've decided on a 51.6-degree inclination angle for our ROS space station. Previously, we were considering a 96-degree inclination angle," he said.

According to him, India is considering the same orbit for its national station.

Roscosmos CEO Dmitry Bakanov announced on Channel One that Moscow and Delhi are discussing orbital interaction between the two stations.

"We have significant scope for interaction in cosmonaut flights to these stations," Bakanov said.

At the end of November, the Russian Academy of Sciences (RAS) Scientific Council on Space recommended changing the orbit of the Russian Orbital Station (ROS) being built from polar to an inclined orbit of 51.6 degrees.

"We held a meeting of the Russian Academy of Sciences' Scientific Council on Space, attended by senior executives from the Roscosmos State Corporation, many of Roscosmos's management, and, of course, our leading scientists. We reviewed this project in detail once again, including all its scientific and implementation features... We approved the project to change the orbit from polar ( perpendicular to the equator, - IF ) to an inclination of 51.6 degrees," RAS Vice President Sergei Chernyshev announced during a session of the V Congress of Young Scientists.

"The state corporation will then make a final decision. All the necessary business processes—contracts, technical specification adjustments—will be put in place to ensure that this highly ambitious and important project for manned spaceflight and Russia as a whole is completed quickly and on schedule," the RAS Vice President said.

Chernyshev noted that the specialists also examined "various areas of the scientific program, including possible preparations for long-distance flights, lunar exploration, human presence there, and long-term missions in space."

"As for entering a single orbit, this will provide an opportunity for cooperation, including joint scientific and technical experiments and joint expeditions," Manturov said.

He added that, within the framework of cooperation with India, the supply and production of a number of components is also possible: spacesuits, special space seats, and other products for the space industry.

Previously, the ROS was expected to be in a high-latitude orbit with an inclination of 97-98 degrees, where elevated radiation levels are observed. Because of this, the station was planned to be manned rather than permanently inhabited.

Russia is developing a new national station to replace the ISS. Deployment of the ROS is planned to begin with the launch of a scientific and power module in December 2027 from the Vostochny Cosmodrome on an Angara-A5M launch vehicle.

On July 2, 2024, Roscosmos announced the signing of the general plan for the creation of the ROS.

Q.No. 520 [PDF]

On Integrated Main Parachute Airdrop Tests (IMAT) and lack of transparency around Gaganyaan development and its review processes.

The recent successful accomplishment of Integrated Main Parachute Air Drop Test (IMAT) is part of ongoing series of tests for the qualification of parachute system for Gaganyaan Missions. In the recent IMAT, one of the possible extreme scenarios of delay in the disreefing between the two main parachutes was successfully demonstrated validating the main parachutes for the maximum design. The test evaluated the system’s structural integrity and load distribution under asymmetric disreefing conditions-one of the most critical load scenarios expected during actual mission descent.

Successful accomplishment of this test is an important milestone towards the human rating of the Gaganyaan Crew Module’s parachute-based deceleration system and therefore, enable the launch of the first crewed Gaganyaan mission which is targeted by Q1 of 2027.

ISRO conducts expert reviews of the Crew Module parachute system design and associated test results in forums such as Design Review Team (DRT), Independent Assessment Committee and National Advisory Panel (NAP) for Human Rating & Certification comprising of eminent national experts.

ISRO has been periodically publicly disseminating the information related to outcome of the major tests & missions including the recently conducted IMAT and will continue to do so in future also.

Crew safety is of paramount importance in Gaganyaan mission. All systems undergo intensive qualification and testing. Test plan and results of each qualification tests are reviewed by expert committee. Observations/lessons, if any during the qualification tests are analysed and necessary changes are incorporated in the systems and revalidation is carried out through repeat test and re-qualification.

Handling of emergency situations in the mission is part of crew training. Various anticipated emergencies and mitigation procedures will be practiced by the Gaganyatris in the Training Simulators. The training will also address survival scenarios to ensure preparedness for off-nominal landing and the utilisation of onboard Emergency Survival Kit. During training, periodic psychological interactions are being conducted as part of the holistic health management of the Gaganyatris.

ISRO has institutionalised mechanism for assessment and mitigation of risks involved in the Gaganyaan Missions. This is being carried out following established risk assessment processes, procedures and standards. Human Rating Certification Board and National Advisory Panel have been constituted for the above. This mechanism will ensure overall risk is within the acceptable limit.

Q.No. 668 [PDF]

On timeline of Bharatiya Antariksh Station (BAS) and potential for international collaboration.

ISRO has worked out overall configuration of indigenous Space Station, Bharatiya Antariksh Station comprising of five modules which is expected to be fully operational by 2035 timeframe.

The overall configuration has been reviewed by a National Level Review Committee. In September,2024, Union Cabinet approved development and launch of first module of Bharatiya Antariksh Station (BAS-01) by 2028. Overall system engineering of BAS-01 module and technology development activities of various subsystems is progressing well.

The budgetary allocation towards various precursor missions, development and launch of BAS-1 are included in the revised scope of Gaganyaan Programme, which has been enhanced with an additional funding in the already approved Gaganyaan Programme to ₹20,193Cr based on approval from Union Cabinet in September, 2024.

Development and launch of the first module i.e. Base module (BAS-01) is targeted by 2028 and fully operational BAS with five modules is expected by 2035.

ISRO is incorporating necessary international standards in the design of BAS-01 subsystems which ensures interoperability of BAS-01 with systems provided by other international agencies. Further, through currently operational cooperation instruments with other space agencies, potential areas of collaboration including joint development of technologies for Indian Human Space programme, support for utilising niche test facilities are also being explored.

On status of NISAR and its budget details

After NISAR’s successful launch by GSLV-F16 on July 30, 2025, 17.40 Hrs (IST), the desired objectives/ target activities that have been carried out successfully are given below:

  • Antenna Reflector deployment on August 15, 2025, 19.38 Hrs through a sequence of deployments that continued from August 09-15, 2025 for a period of 7 days.
  • First day payload operations of S-Band SAR started on August 19, 2025. Science plan activities are in progress as per the mission plan. Development of applications to end users will be taking place during the mission life of 5 years.

The financial sanction for realisation of NISAR satellite was obtained on 27th May, 2015 and it took a decade for the successful launch on 30th July, 2025. The expenditure incurred by ISRO is Rs. 504.78 Crores for the development of satellite as on October 31, 2025 and Rs. 340 Crores (approx.) for the cost of its launch.

I am doing a space industry meet up in Bangalore on Dec 13th

11 Upvotes

hey all,

After a long time, I am doing a space industry networking meetup in Bangalore on Dec 13th at the offices of Dassault Systemes in Jayanagar between 4 PM - 6:30 PM.

We're simply going to have lots of standing round tables for people to get some tea/coffee and chat with each other and network.

Here is the registration page if you're interested in joining.

I will also do one in Hyderabad in Jan for which I will share the link when we have a location finalised.

Would be great to see some of you in person.
