More than half a century after astronauts last left footprints on the lunar surface, humanity is preparing to return to the moon. The excitement surrounding NASA's Apollo program once captivated the world, and now NASA hopes to rekindle that same sense of wonder with its modern lunar effort, the Artemis program.
NASA's Artemis II launch is scheduled for the first week of April. It'll be the first human mission to the moon since 1972, and it should be quite the achievement for the Artemis program. Now, NASA has released a new tool that lets the public track Artemis II in real time.
The Artemis program is NASA's long-term effort to return humans to the moon and establish a sustained presence there for the first time since the Apollo program. The program aims to land astronauts near the lunar south pole, develop new technologies for long-term exploration and use the moon as a stepping stone for future missions to Mars.
The Artemis Real-time Orbit Website, dubbed AROW, is already available to the public, although there isn't much to see since the launch is still a few weeks away. It's also available directly from the NASA app if you're using a mobile device. The site lets the public visualize data collected by sensors on Orion and sent to the Mission Control Center at NASA's Johnson Space Center in Houston.
The website is simple to navigate. You'll see a visual representation of Artemis II's progress, including its speed, distance from Earth and distance to the moon. Mobile app users get all of the above, along with an extra augmented reality tracker that lets you point your phone at the sky and see where Artemis II is relative to your position on Earth. It works much like Google Star Map and other stargazing apps that use similar technology.
According to NASA, tracking will be available once the Orion capsule separates from the rocket's upper stage, which is expected about 3 hours after the upcoming April launch. The site will then update its information in real time for the entire 10-day mission.
NASA is also making flight data available for download so that people interested in creating their own content, such as visualizations or tracking apps, can do so. The data will include all sorts of things, including state vectors, which are data that "describe precisely where Orion is located and how it moves." That same data will be used by NASA to study Orion and make improvements for future Artemis missions.
An exact launch date for Artemis II hasn't been set, but the agency plans on launching the mission no earlier than April 1. The launch was originally scheduled for February, but it was delayed multiple times due to a hydrogen leak and a helium flow issue. NASA says it has since fixed both issues.
