Quick stats

  • 1,817 launch vehicle variants across 392 families
  • 1,462 engines from 317 manufacturers
  • 1,596 stage configurations
  • 21 propellant groups (solid, liquid, hybrid, etc.)

Usage

from datasets import load_dataset

vehicles = load_dataset("juliensimon/gcat-launch-vehicles", "vehicles", split="train")
engines = load_dataset("juliensimon/gcat-launch-vehicles", "engines", split="train")
stages = load_dataset("juliensimon/gcat-launch-vehicles", "stages", split="train")

vdf = vehicles.to_pandas()

# Largest launch vehicles by mass
print(vdf.nlargest(10, "launch_mass_t")[["lv_name", "launch_mass_t", "leo_capacity_kg"]])

# Engines by specific impulse
edf = engines.to_pandas()
print(edf.nlargest(10, "isp_s")[["name", "fuel", "oxidizer", "isp_s", "thrust_kn"]])

# Orbital-class vehicles only
orbital = vdf[vdf["class"] == "O"]
print(f"{len(orbital)} orbital-class vehicles")

Data source

GCAT (General Catalog of Artificial Space Objects) by Jonathan McDowell, Harvard-Smithsonian Center for Astrophysics. GCAT is the most comprehensive public catalog of space objects and launch vehicles, widely used in the spaceflight research community.

Update schedule
