ISRO Missions Data

Part of the Orbital Mechanics Datasets collection on Hugging Face.

Comprehensive data on the Indian Space Research Organisation (ISRO): 112 spacecraft, 81 launch vehicles, 53 customer satellites launched for 22 countries, and 44 research centres across 16 Indian states.

Dataset description

ISRO is India's national space agency, responsible for one of the most cost-effective space programs in the world. Since its founding in 1969, ISRO has developed indigenous launch vehicle families -- the Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV), and the heavy-lift GSLV Mk III (LVM3) -- and built satellite constellations for remote sensing (IRS series), communications (INSAT/GSAT series), and navigation (NavIC/IRNSS). ISRO has achieved landmark interplanetary missions including Chandrayaan-1 (which confirmed water on the Moon), the Mars Orbiter Mission (Mangalyaan, India's first interplanetary probe), Chandrayaan-3 (which successfully landed near the lunar south pole in 2023), and is developing the Gaganyaan crewed spaceflight program.

This dataset captures four dimensions of ISRO's space program: the full catalog of ISRO-built spacecraft, the complete roster of launch vehicles from early SLV-3 experimental flights through modern PSLV and GSLV missions, customer satellites launched by ISRO for international clients (a major commercial activity, with PSLV having launched satellites for dozens of countries), and the network of ISRO research centres and facilities distributed across India.

Quick stats

112 ISRO spacecraft from Aryabhata (1975) to present
81 launch vehicle missions (SLV, ASLV, PSLV, GSLV, LVM3)
53 customer satellites for 22 countries
44 research centres across 16 Indian states

Usage

from datasets import load_dataset

spacecraft = load_dataset("juliensimon/isro-missions", "spacecraft", split="train")
launchers = load_dataset("juliensimon/isro-missions", "launchers", split="train")
customer_sats = load_dataset("juliensimon/isro-missions", "customer_satellites", split="train")
centres = load_dataset("juliensimon/isro-missions", "centres", split="train")

# List all ISRO spacecraft
sdf = spacecraft.to_pandas()
print(sdf[["id", "name"]].to_string(index=False))

# Customer satellites by country
cdf = customer_sats.to_pandas()
print(cdf.groupby("country").size().sort_values(ascending=False).head(10))

# PSLV missions
ldf = launchers.to_pandas()
pslv = ldf[ldf["id"].str.startswith("PSLV")]
print(f"{len(pslv)} PSLV missions")
