The Geological Survey of India (GSI) has launched 22 permanent global positioning system (GPS) stations across India to identify seismically hazardous zones and encourage mapping activities.
These 22 stations are part of the 35 stations planned by GSI to establish and maintain a network of continuously operating 35 permanent GPS stations.
Fact Box: Bhuvisamvad
Bhuvisamvad is an app launched by the Ministry of Mines to facilitate interaction between geo-scientists and university and college students.
22 stations inaugurated are based at Kolkata, Thiruvananthapuram, Jaipur, Pune, Dehradun, Chennai, Jabalpur, Bhubaneswar, Patna, Raipur, Bhopal, Chandigarh, Gandhinagar Vishakhapatnam, Agartala, Itanagar, Mangan, Jammu, Lucknow, Nagpur, Shillong and Little Andaman.
13 More Stations Would come up at Aizawl, Faridabad, Uttarkashi, Pithoragarh, Cooch Behar, Zawar, North Andaman, Middle Andaman, South Andaman, Ranchi, Mangalore, Imphal and Chitradurga.
These stations are meant to delineate high strain zones for earthquake probability, determine a seismic motion on faults that may lead to a rupture and produce thematic maps with high positional accuracy.
Geological Survey of India
Geological Survey of India (GSI) was established in 1851 primarily to find coal deposits for the Railways. Over the years GSI has not only grown into a repository of geoscience information required in various fields in the country but has also attained the status of a geo-scientific organisation of international repute.
The main functions of GSI attached to the Ministry of Mines is to create and update of national geoscientific information and mineral resource assessment through ground surveys, airborne and marine surveys, mineral prospecting and investigations, multi-disciplinary geoscientific, geotechnical, geo-environmental and natural hazards studies, glaciology, seismotectonic study, and carrying out fundamental research.

The Crew Dragon capsule of Space X has successfully docked with the International Space Station.
SpaceX Crew Dragon Capsule
- The demonstration mission is named as Demo-1.
- It was a test mission before it can begin taking US astronauts into space.
- After the successful docking, the crew members of International Space Station opened the hatch of the space capsule and, for the first time, penetrated its interior in space.
- The Dragon Capsule had carried Ripley, a test dummy named after the heroine from Alien Movies, an untethered plush toy, 400 pounds (about 181 kg) of supplies and experiments to the ISS.
- During the mission, Flight computers guided the spacecraft directly into a docking port, unlike the previous cargo Dragon spacecraft that were attached to the space station after captured by a robotic arm.
International Space Station
The International Space Station is a habitable artificial satellite in low Earth orbit. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres and circles the Earth in roughly 92 minutes and completes 15.5 orbits per day
The ISS programme is a joint project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).
Demo-1 was a dress rehearsal to demonstrate that the vehicle is reliable and safe so that NASA can resume manned flights from US soil this year and reduce its reliance on Russia to ferry its astronauts to the space station since the end of the US space shuttle program in 2011 after a 30-year run.
