WorldView-2 satellite involved in ‘Debris causing event’
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.

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.

He is currently the managing editor of the student run newspaper, the Washburn Review. He also writes a blog, called Orbital Velocity, about the space station. His passion for space ignited when he watched space shuttle Discovery leap to space on Oct. 29, 1998. He saw his first in-person launch on July 8, 2011 when the space shuttle launched for the final time. 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 that his true calling was communicating to others about space exploration and spreading that passion.
