| # NASA EVA Chronology |
|
|
| *Part of the [Astronomy Datasets](https://huggingface.co/collections/juliensimon/astronomy-datasets-69c24caf2f17e36128946743) 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 |
|
|
| ```python |
| 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) |
| ``` |
