## What is ISS Explorer?

The ISS explorer is an interactive tool for exploring the parts and pieces of the International Space Station (ISS).  The application allows the user to view a 3D model of the ISS, rotate it, zoom into it, and select different parts and pieces.

When the application starts, you can see a view of the entire ISS with category labels. Tabs are available on the left hand side of the screen which allow you access to information, the hierarchy, settings and application information. From this point, you can zoom into the station, revealing more labels of visible parts. The station can also be rotated to view from different angles. If a part is selected, the part is isolated so that you can focus on the specific piece. The information tab shows information about the currently isolated part.

Inside the hierarchy tab, you can turn parts on or off, turn labels for parts on or off, turn parts transparent, or select a part to focus on. The parts are organized in a hierarchy to allow for systems to be described and displayed. This includes things such as truss, modules, and external platforms.

The Information tab shows information about the current isolated part, system, or the full ISS if the entire station is shown.

## Key features

- Interactive 3D ISS model

### 5/5 — Space suits

Please add the space suits inside the space station

### 5/5 — La nouvelle version nous ouvre TOUT !

*2023-09-30*

La nouvelle version 5.0.2 de l'ISS Explorer nous ouvre absolument TOUT, y compris le territoire de la Fédération de Russie, ce qui est une première sur cette application.

Est-ce une manière scientifique de rappeler à la Russie que nous sommes TOUS sur le même bateau ? Peut-être...

De plus, on gagne en qualité visuelle HD et en navigation intèrieure comme extèrieure avec cette nouvelle version, ce qui explique pleinement le passage de 200Mo à près de 900Mo au moment du téléchargement de l'application.

Un très grand merci pour cette application pleine d'enseignement !

### 5/5 — Fantastic

*2022-07-16*

Thank you for updating it with all the current modules.

### 5/5 — Wow!

*2019-06-19*

Don’t know how I missed this app... but this is exactly what I’ve been looking for ever since a mysterious new gold disc array showed up on the HDEV experiment a couple months ago.  I couldn’t find a 3D model to give a clue as to where located... looks like it’s attached to Columbus ESA module between the camera and the Soyuz capsules (rear facing camera).

Thanks NASA et al 🖖 !!

### 5/5 — Must download app! If you love CAD, you’ll love this!

*2019-04-06*

This ISS app is amazing. I love how it’s components are visualized in computer aided design format, with great accuracy to the current configuration and informative annotations to each component respectively.
