Experience the thrill of space exploration with Artemis II Tracker, a comprehensive app designed to monitor NASA's groundbreaking Artemis II mission—the first crewed journey to the Moon since Apollo 17 in 1972. This innovative tool offers space enthusiasts, students, and space professionals an immersive way to follow the mission's progress, crew activities, and space weather conditions in real time.

Artemis II Tracker provides dynamic, real-time updates with an animated cislunar map displaying the Orion spacecraft as it orbits between Earth and the Moon. Users can easily view the spacecraft's current distance from Earth and the Moon, its velocity, and altitude status. A built-in signal delay calculator simulates the light-speed communication lag, offering an authentic experience of deep-space communication challenges.

Additionally, the app features a distance record tracker, engaging users to wonder if Artemis II will surpass Apollo 13's historic record of 248,655 miles. Once the mission commences, automatic switching to live NASA telemetry data (AROW) ensures users stay updated with the most accurate information.

The Mission Dashboard includes a precision countdown to launch and displays the current mission phase with detailed status. Enjoy the daily NASA Astronomy Picture of the Day with quick access to full articles, and keep informed with live space weather data—such as solar flares, coronal mass ejections, and geomagnetic storms—sourced directly from NASA's DONKI service. This helps users understand the environmental conditions that can affect crew safety and spacecraft operations during the lunar mission.

Follow the day-by-day breakdown of the Artemis II mission, from launch to splashdown. The timeline includes key milestones and maneuvers such as high Earth orbit, translunar injection, lunar flyby, return, reentry, and splashdown, providing a clear overview of each phase of this ambitious 10-day mission.

Get to know the diverse crew members leading this historic voyage. The app features detailed bios of all four astronauts, including their mission roles, agency backgrounds, and career highlights. Notably, Jeremy Hansen becomes the first Canadian beyond low Earth orbit, representing the international spirit of space exploration.

Understanding space weather is critical for deep-space missions. Artemis II Tracker utilizes NASA's DONKI data to provide real-time solar activity, including coronal mass ejections, solar flares, and geomagnetic storm alerts. This feature ensures that both crew members and mission controllers are informed about space environment fluctuations that could impact safety or spacecraft systems during the lunar mission.

The app offers a unit toggle allowing users to switch between imperial and metric measurements for miles/mph and kilometers/km/h. For advanced tracking, a Mission Control optional upgrade provides extra features suited for enthusiasts and professionals alike. Supporting the app through optional tips helps maintain its development and enhancement. The portrait-friendly dark interface, inspired by NASA Mission Control, offers a sleek, immersive viewing experience optimized for all device types.

All mission data is rigorously sourced from official NASA APIs (api.nasa.gov). Space weather insights are derived from NASA's DONKI database, ensuring users receive accurate and timely environmental information. The app employs physics-based orbital mechanics simulations for pre-launch telemetry and utilizes NASA's AROW system for post-launch live tracking.

Note that Artemis II Tracker is an independent project and is not officially affiliated with or endorsed by NASA. All data and imagery are used under NASA's media guidelines, emphasizing user trust and the highest standards of accuracy.
