Satellites — Overview
  • Natural Satellite: Moon
  • Artificial Satellite: Man-made satellite placed in space
  • First Artificial Satellite: Sputnik-1 (1957, Soviet Union)
  • First Indian Artificial Satellite: Aryabhata (1975)
Types of Satellites by Orbital Path
Orbit TypeDetails
Low Earth Orbit (LEO)Roughly 160–2,000 km; circular or elliptical
Solar-Synchronous OrbitAltitude 500–1000 km; near-polar orbit, North to South
Geosynchronous OrbitPeriod equals Earth's rotation; geostationary is the circular equatorial case at about 35,786 km
Highly Elliptical Molniya OrbitAltitudes 504–39,834 km
⚠ EXAM TRAP Geosynchronous orbit altitude (36,000 km) is often confused with LEO (200–2000 km) — remember LEO is much closer to Earth, used for remote sensing; Geosynchronous is for communication satellites.

Chandrayaan Missions
MissionDetails
Chandrayaan-1Launched 22 Oct 2008; PSLV-C11 from Sriharikota; India's first lunar mission
Chandrayaan-2Launched 22 Jul 2019; targeted South Pole of Moon; Launch Vehicle: GSLV-MkIII (Bahubali); partially successful; impact point named Tiranga Sthal
Chandrayaan-3Launched 14 Jul 2023; Lander: Vikram, Rover: Pragyan; Launch Vehicle: LVM3-M4; landing site: Shiv Shakti Sthal
Other Major Missions
MissionDetails
Aditya L-1Launched 2 Sep 2023; PSLV-C57; India's first mission to study the Sun
100th Launch from Sriharikota29 Jan 2025; Satellite: NVS-02 using GSLV F-15
ISRO's First LaunchSLV-3E1 / Rohini Technology
Future Missions
  • India's human-spaceflight programme; the first uncrewed G1 mission with Vyommitra is targeted for Q4 2026, followed by further uncrewed tests and the first crewed mission targeted in 2027
  • NISAR — A joint NASA–ISRO dual-band radar Earth-observation satellite; launched by GSLV-F16 on 30 July 2025 into a 743-km Sun-synchronous orbit and now operational
  • ISRO Chairman V. Narayanan has announced India's own Space Station by 2035, and an Indian astronaut landing on the Moon and returning independently by 2040.
Astronauts
AchievementPersonDetails
First Indian AstronautRakesh Sharma1984; travelled on Soyuz T-11
First Woman of Indian Origin in SpaceKalpana Chawla1997, 2003; travelled on Space Shuttle Columbia
Second Woman of Indian Origin in SpaceSunita Williams2006
First Indian to reach ISSShubhanshu ShuklaAxiom Mission 4 (Ax-4)
⚠ EXAM TRAP Kalpana Chawla and Sunita Williams are Indian-ORIGIN (US citizens); Rakesh Sharma is the first genuinely Indian citizen in space; Shubhanshu Shukla is the first Indian to reach the ISS specifically. Three distinct "firsts."

Third GenerationINSAT-3A, 3B, 3C, 3D, 3DR and 3E
Fourth GenerationINSAT-4A, INSAT-4B, INSAT-4C and INSAT-4CR; INSAT-4C's launch was unsuccessful and 4CR followed
Launch Vehicle Technology
VehicleKey Details
SLV-3India's first launch vehicle; launched 18 July 1980; India became the 6th member of the Space Club (after USSR, USA, France, Japan, China)
PSLVPSLV-D1 flew on 20 September 1993 but was unsuccessful; PSLV-D2 succeeded on 15 October 1994; PSLV is a four-stage workhorse used especially for LEO/SSO missions
GSLVGSLV Mk II first flew on 18 April 2001 and can place about 2.25 t into GTO; LVM3 is the separate heavier launcher with over 4 t GTO capability
⚠ EXAM TRAP India was the SIXTH country in the Space Club — the order was USSR, USA, France, Japan, China, then India (1980 with SLV-3). Sequencing this list correctly is a common exam ask.
