Space Missions Database

Part of the Orbital Mechanics Datasets collection on Hugging Face.

Comprehensive database of 25,137 space missions — both crewed and uncrewed — sourced from Wikidata.

Dataset description

This dataset draws on Wikidata's structured knowledge base using three entity types: space missions (Q2133344), crewed spaceflights (Q1248784), and uncrewed spaceflights (Q12795915). It is maintained by the WikiProject Spaceflight community and updated as new missions are flown and documented.

Note: Wikidata coverage is uneven — most entries have only a name and Wikidata ID. Columns with <5% data coverage are automatically dropped during pipeline processing.

Schema

Column Type Description
wikidata_id string Wikidata entity ID (e.g. Q183294)
name string Mission name
operator string Operating agency or organization (~13% coverage)

Additional columns (launch_date, destination, etc.) appear when Wikidata coverage exceeds 5%.

Quick stats

  • 25,137 total missions in the database
  • Top operators: National Aeronautics and Space Administration (202), Alaska Department of Transportation & Public Facilities (149), Airports Authority of India (109), Soviet space program (93), Roscosmos State Corporation (85)

Usage 

from datasets import load_dataset

ds = load_dataset("juliensimon/space-missions", split="train")
df = ds.to_pandas()

# Missions by operator
if "operator" in df.columns:
    print(df["operator"].value_counts().head(10))

# List all missions
print(df[["name", "wikidata_id"]].head(20))
