Explore the diverse ecosystem of experiments being researched on the International Space Station – both completed and ongoing. Investigate the results and benefits of many of the experiments and find out why performing research in a microgravity environment is so important. The Space Station Research Explorer provides current information on ISS experiments, facilities and research results through video, photos, interactive media, and in-depth descriptions.

The Experiments section provides access to the six main experiment categories and their subcategories. Experiments are depicted as dots within the category system and the stems connecting the dots to the system depict the length of time the experiment spent on orbit. Users can drill down to see specific experiments within the categories and subcategories or search for a specific experiment or subject using the search option. Experiment descriptions consist of links, images, and publications if available. The Experiments section can be further narrowed by selecting a specific expedition and sponsor by using the dials at the top right of the screen. Experiments can be added to a favorites list for quick access.

The Lab Tour section provides an interior view of three of the station modules; Columbus, Kibo, and Destiny, and an exterior view of seven external facilities; ELC1-4, Columbus-EPF, JEM-EF and AMS. The module interiors can be navigated by dragging up and down to see different sides of the module and left and right to view any racks not shown on the screen. Tapping a rack gives a brief description of the rack and an experiment description if available. For the externals, the platform is shown and can be rotated and zoomed. Payloads on the external racks are labeled and the labels can be selected for more information.

The Facilities section provides information on all of the facilities available on board the International Space Station that can be used to conduct experiments. The facilities are broken up into six categories: Physical Science, Human Research, Biology and Biology and Biotechnology, Earth and Space Science, Multipurpose, and Technology Development and Demonstration. These include facilities such as centrifuges, additive manufacturing facility and glove boxes.

The Benefits section provides information on Human Health, Economic Development, Innovative Technology, Earth Benefits and Global education. Selecting a section allows the benefits to be investigated further.

The Media section provides links to Science related videos.

The last section contains links to other Space station research sites and NASA applications.

Great App

First off, SSRE is great for the general public to get a better understanding of the work aboard the ISS and even a great tool for people who work under NASA (myself) to use to better understand layout of station for ops. I did notice that ELC 2 and ELC 4 need to be swapped on the facilities page to match stations configuration. Other than that I love the app and that you can spin the items around to get a better understanding of the equipment.

Excellent educational tool for everyone of all ages

This app is super useful to learn about the International Space Station. Has tons of robust interactive information about it and how it works. Definitely recommend to anyone wanting to teach about it or just to learn.

Bigger screens help

This is really the best app I've ever seen to access a huge amount of information. It is a lot easier on a huge phone or iPad.
