A commercial Earth observation satellite was involved in a “debris causing event” yesterday, according to the Joint Space Operations Center (JSpOC), the part of the United States Defense Department that tracks space objects. The satellite in question, WorldView-2, is owned and operated by DigitalGlobe.

JSpOC announced the event in a tweet and added the satellite has been confirmed as operational and maneuverable. However, eight pieces of debris were tracked. It is unclear exactly when the event occurred or how many of the pieces, if any, are part of WorldView-2.

“Earlier today JSpOC issued a ‘debris causing event’ notification related to DigitalGlobe’s WorldView-2 satellite,” DigitalGlobe tweeted. “WorldView-2 is currently operational and is performing standard maneuvering and imaging tasks.”

Likely in an effort to show that their satellite was still functioning, the company released via twitter an image of downtown Oakland, California. The company noted the image was collected at 2:34 p.m. PDT (21:34 GMT) July 19.

According to SpaceNews, Air Force Capt. Nicholas Mercurio, a spokesperson for the U.S. Strategic Command’s Joint Functional Component Command for Space and the 14th Air Force, said DigitalGlobe has started an investigation into what happened.

WorldView-2 offers commercial panchromatic imagery with a resolution of less than a half-a-meter per pixel. The satellite was built by Ball Aerospace and launched on Oct. 8, 2009, atop a United Launch Alliance Delta II rocket from Vandenberg Air Force Base’s Space Launch Complex 2W.

The satellite is joined by WorldView-1, which launched in 2007; GeoEye-1, which was placed into orbit in 2008; and WorldView-3, which took to the skies in 2014. WorldView-2 takes a new picture of any place on Earth every 1.1 days.

While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor.
