Why in news?
- US space agency NASA will train an Indian astronaut for a mission to the International Space Station by the end of 2024.
- This was revealed by the organisation’s administrator Bill Nelson during his Delhi visit.
- He also said another major programme emerging from India-US collaboration would be the NISAR satellite, which is to be launched in the first quarter of 2024.

- News Summary
Indian Space Station
- India's planned space station is called the Bharatiya Antariksha Station.
- It will be built by India and operated by the Indian Space Research Organisation (ISRO).
- The station is expected to be completed by 2035.
- Recently, PM Modi called on ISRO scientists to set up an Indian Space Station by 2035 and send an Indian to the moon by 2040.
- The Indian space station will be smaller than International Space Station (ISS).
- It will have a mass of 20 tonnes (ISS - 450 tonnes and Chinese Tiangong Space Station - 100 tonnes) and will be used for microgravity experiments.
- It will orbit Earth at an altitude of around 400km.
- What needs to be done?
- Develop new technologies
- India has shown its prowess in satellite development, but constructing and maintaining a space station requires a completely different set of skills.
- It involves life support systems, radiation protection, and long-term structural integrity.
- India will need to significantly upgrade its technological capabilities to meet these demands.
- Increase the budget
- India will have to seek international collaborations and explore private-sector involvement to ensure adequate funding.
- Gain expertise in human spaceflights
- To build and operate a space station, a well-trained team of astronauts is indispensable.
- India must invest in human spaceflight programs, astronaut training, and the development of necessary infrastructure for crewed missions.
NASA-ISRO Synthetic Aperture Radar (NISAR)
- NISAR, or NASA-ISRO Synthetic Aperture Radar, is a joint project between NASA and ISRO.
- When it is launched, NISAR will be the first radar imaging satellite to use dual frequencies.
- The mission will survey all of Earth's land and ice-covered surfaces every 12 days. It has a three-year duration.
- The main aim of the NISAR satellite is to observe the most complex natural processes of the planet, including ecosystem disturbances, ice-sheet collapse, as well as earthquakes, volcanoes and landslides.
- NISAR is a Low Earth Orbit (LEO) observatory that will measure Earth's changing ecosystems, dynamic surfaces, and ice masses.
- It will also gather information related to biomass, natural hazards, sea level rise, and groundwater.
- NISAR will use two distinct radar frequencies: L-band and S-band.
- This will enable it to measure changes on Earth's surface with precision, down to less than a centimeter.
News Summary: NASA to train an Indian astronaut for ISS mission
- NASA will help train an Indian astronaut
- That astronaut will fly to the International Space Station at the end of 2024.
- The astronaut would be selected by ISRO.
- The selection will likely be from among the four persons who have undergone basic space astronaut training in preparation for the Gaganyaan mission.
- The science objectives for the two-week long mission will be decided by India.
- Joint working group set up
- Both NASA and ISRO have set up a joint working group to explore collaborating on radiation impact studies, micro meteorite and orbital debris shield studies, space health and medicine aspects.
- Plan to decommission the International Space Station (ISS)
- NASA plans to decommission the ISS by 2031.
- The ISS will be removed from its orbit around Earth and plunged into the ocean at a point farthest from human civilization.
- Commercial replacement facilities are expected to step in before that time, allowing NASA to maintain a constant human presence in low-Earth orbit.
