Websites
NASAโs Artemis II mission drove a major surge in traffic across the agencyโs websites, with NASA.gov recording 125.1 million pageviews between April 1 and 10 โ more than double the roughly 50 million logged in all of March โ reflecting intense public interest in following the mission in real time. On launch day alone, NASA sites saw 17.6 million pageviews from 8.3 million visitors, with the Artemis Real-Time Orbit Website (AROW) drawing 797,796 pageviews,
Interest spiked again during the April 6 lunar flyby, generating 16.5 million pageviews from 6.2 million visitors; AROW registered 1.9 million pageviews โ boosted by more than 440,000 Google referrals โ while the NASA homepage reached 2.3 million. Splashdown day brought another surge to NASA-owned websites, with more than 16 million pageviews from 6.1 million visitors as audiences followed the Artemis II crewโs return; AROW drew over 1 million pageviews and surpassed 11 million cumulative views since launch. Together, these metrics show sustained, high-volume engagement across all mission milestones, with live hubs, broadcast pages, and real-time tracking consistently ranking among the most-visited content throughout launch, flyby, and splashdown.
Social Media
Public reaction to NASAโs Artemis II mission remained largely steady across launch week, with neutral and positive posts dominating the online conversation. Neutral sentiment consistently led daily discussion, ranging from 47 to 60 percent, while positive reactions accounted for 30 to 42 percent, fueled by excitement over the crewโs historic lunar journey, striking mission imagery, and renewed interest in deep space exploration. Engagement spiked around major mission milestones, with NASA accounts generating 35 million engagements on splashdown day content alone and 261 million from March 27 to April 13, underscoring how closely audiences followed each phase. Strong amplification from major news outlets, brands, and international partners, further boosted visibility and cemented Artemis II as a global cultural moment.
NASAโs Artemis II mission drove major social media growth across the agencyโs flagship and missionโspecific accounts, with follower numbers climbing steadily from rollout through the lunar flyby and splashdown. Internal tracking shows NASAโs flagship Instagram account added more than 4.6 million followers, while the Artemisโdedicated Instagram account grew by 2 millionโa 66% increase over the course of the mission. Significant gains were also recorded across X, Facebook, and YouTube, including a 2 million increase in YouTube subscribers and NASAโs flagship Facebook page climbing by 1.7 million. Collectively, these gains highlight how Artemis IIโs humanโspaceflight narrative, realโtime crew updates, and highly visual moments drew millions of new followers across platforms.

Mission Images
NASA has long shaped its legacy through unforgettable imageryโpictures that donโt just document history but become part of it. ArtemisโฏII carries that tradition forward with a growing collection of images capturing every phase of the mission, from the anticipation of launch to the sweep of a lunar flyby and splashdown . For those eager to explore more, the missionโs dedicated image galleries offer a rich visual journey, complemented by additional photos on the NASA Headquarters official Flickr account and the NASA Image and Video Library .
NASA Campaigns
Moon Mascot: NASA Artemis II ZGI Design Challenge
Last year, the Moon mascot design contest received thousands of submissions from more than fifty countries for the Artemis II missionโs zeroโgravity indicator. This plush item serves a special purpose โ it begins to float once the astronauts reach space, signaling the onset of zero gravity. It also provides a comforting reminder of Earth when the crew is far from home.
Ultimately, the Artemis II astronauts selected โRiseโ โinspired by the iconic Earthrise photograph captured during the Apollo 8 mission and designed by Lucas Ye of Mountain View, Californiaโas the zeroโgravity indicator that will accompany them around the Moon. โRiseโ also features a small pouch that will carry an SD card containing all 5.6 million names submitted through the Send Your Name with Artemis campaign.
Send Your Name with Artemis II
NASA invited the public to join the agencyโs Artemis II test flight as four astronauts ventured around the Moon and back to test the systems and hardware needed for deep space exploration. As part of the agencyโs โSend Your Name with Artemis IIโ effort, anyone could claim their spot by signing up before Jan. 21, 2026. Participants launched their names aboard the Orion spacecraft and SLS (Space Launch System) rocket alongside NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen.

NASAโs Artemis Program
The Artemis II mission launched April 1, 2026, on NASAโs SLS (Space Launch System) rocket from Kennedy Space Center in Florida. During the nearly 10โday test flight, the crew achieved the missionโs primary objectives, including testing its life support systems; manually piloting the Orion spacecraft; performing maneuvers to propel Orion to the Moon and adjust its course; conducting a lunar flyby with unprecedented views of the Moonโs far side; and completing a safe re-entry and recovery. The astronauts also set a record for the farthest distance traveled by humans away from Earth.
As part of a Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly challenging missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and lay the groundwork for sending the first astronauts โ American astronauts โ to Mars.
