## ANSWER

MINISTER OF STATE IN THE MINISTRY OF PERSONNEL, PUBLIC GRIEVANCES & PENSIONS AND IN THE PRIME MINISTER'S OFFICE (DR. JITENDRA SINGH):

****

- (a) 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.
- (b) 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.
- (c) 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.
- (d) 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.
- (e) Gaganyaan,  first  crewed  demonstration  mission  will  enable demonstration of capabilities for safe human transportation to Low  Earth  Orbit  (LEO)  and  return  back  to  Earth.  Bharatiya Antariksh  Station  (BAS)  is  the  next  logical  step  in  sustained

Indian Human  Space  Programme.  It  will open up further avenues in space exploration, which will lead to utilisation of the  unique  microgravity  environments  in  LEO  for  advanced scientific  research  and  technology  development  activities  as well as support further Indian human exploration missions (i.e.) Indian  landing  on  Moon  as  envisioned  in  India's  Space  Vision 2047.
