UFO-like object spotted during SpaceX Starship livestream
Mysterious blue streak sparks alien theories during historic rocket launch.
1Historic Starship launch
SpaceX achieved a milestone by launching the world's most powerful rocket, Starship, into orbit on September 28, 2026. The uncrewed mission launched from Texas's Starbase complex for a planned 10-hour Earth orbit. This marked the first orbital attempt after 13 previous test flights fell short. While the rocket reached orbit, an engine unexpectedly shut down during ascent, leading to mission adjustments.
2Mysterious blue streak
Viewers spotted a pale blue, curved light streak trailing Starship about 7 minutes 55 seconds into flight. The object appeared with a brighter white tip against space's darkness, prompting immediate social media reactions. Screenshots circulated widely, with users describing it as 'bigger than a city' and resembling a 'mothership.' The footage provided no scale reference, leaving the object's true size and distance ambiguous.
3Alien theories explode
X users overwhelmingly interpreted the anomaly as extraterrestrial, with comments like 'The Greys are checking on us' referencing UFO lore. Some tagged Elon Musk directly, asking if it was alien technology. Engineer Kyle Holl humorously connected it to Starship's engine failure: 'An engine out and then an alien battle cruiser uncloaks.' Despite viral speculation, neither SpaceX nor Musk commented on the phenomenon during or after the livestream.
4Plausible technical explanation
User Dean Scott proposed the streak was residual gas from Super Heavy booster's engines during separation and return burn. He explained the apparent 'rise' resulted from Earth's bright horizon initially obscuring the plume. Another user verified this by reviewing earlier footage showing a fuzzy blue-white patch at 6 minutes 35 seconds. While this explanation gained traction, it didn't quell alien theories among conspiracy-minded viewers.
5Splashdown explosion
Starship's flight ended abruptly when it flipped for splashdown at 11:58 AM ET, erupting into a fireball upon water impact. Onshore cameras captured the booster exploding mid-air. SpaceX spokesperson Dan Huot acknowledged the 'not quite soft' landing during the livestream. Despite the fiery conclusion, NASA Administrator Jared Isaacman congratulated SpaceX for achieving orbit—the mission's primary objective.
6Artemis program implications
This test flight aimed to build confidence for NASA's Artemis moon landing planned for 2028, which will use a modified Starship. While the engine failure and explosion raise questions, their impact on Artemis timelines remains unclear. SpaceX ultimately needs Starship to achieve controlled landings in Texas for crewed missions. Current tests intentionally end at sea with no recovery plans, accepting vehicle loss.
7Public engagement strategy
SpaceX's decision to livestream the mission—including anomalies—fueled unprecedented public engagement. Over 3 million concurrent viewers witnessed both the technical achievement and unexplained phenomena in real time. This transparency, while generating alien theories, also showcased SpaceX's iterative testing approach. The viral moment may boost interest in future launches, despite the ambiguous nature of the visual anomaly.
8Science communication challenge
The incident highlights the difficulty of explaining complex aerospace phenomena to lay audiences. While engineers recognized probable booster exhaust effects, most viewers defaulted to sensational interpretations. This gap persists despite SpaceX's detailed livestream commentary, suggesting even transparent communication can't always overcome ingrained cultural narratives about UFOs during space missions.
