NASA EVA Chronology

Part of the Astronomy Datasets collection on Hugging Face.

Complete chronology of all 375 extravehicular activities (spacewalks) performed by NASA and Roscosmos astronauts and cosmonauts, from 1965 to 2013 -- totalling 1,987 crew-hours outside the spacecraft.

Dataset description

This dataset contains the official NASA EVA chronology covering every spacewalk by US and Russian crews. Each record includes the EVA sequence number, date, crew members, vehicle (Gemini, Apollo, Skylab, Shuttle, ISS, etc.), duration in H:MM format plus a computed duration_minutes column, and a free-text description of the purpose and activities.

Schema

Column	Type	Description
eva_number	Int64	Sequential EVA number
country	string	Country (USA / Russia)
crew	string	Crew member(s)
vehicle	string	Spacecraft or station (Gemini, Apollo, ISS, etc.)
date	datetime	Date of EVA
duration	string	Duration in H:MM format
duration_minutes	float64	Duration in total minutes
purpose	string	Free-text description of EVA activities

Quick stats

• 375 EVAs (236 USA, 139 Russia)
• 1965 to 2013
• 1,987 total crew-hours
• 151 vehicles: Soyuz TM-26 Mir 24 (7), Soyuz TM-27 Mir 25 (6), Soyuz T-10 Salyut 7 (6), Soyuz TM-12 Mir (6), Apollo 15 (6)

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/nasa-eva-chronology", split="train")
df = ds.to_pandas()

# EVAs per vehicle
print(df["vehicle"].value_counts())

# Total spacewalk hours by country
by_country = df.groupby("country")["duration_minutes"].sum() / 60
print(by_country)

# Longest EVAs
longest = df.nlargest(10, "duration_minutes")[["date", "crew", "vehicle", "duration"]]
print(longest)
