NASA Statement on Suspicious Terra Spacecraft Events

According to NASA PAO: “NASA experienced two suspicious events with the Terra spacecraft in the summer and fall of 2008. There was no manipulation of data, no commands successfully sent to the satellite, and no data captured. NASA notified the Department of Defense, which is responsible for investigating any attempted interference with satellite operations. While we cannot discuss additional details regarding the attempted interference, our satellite operations and associated systems and information are safe and secure. We are complying with the guidance in the National Space Policy to protect our critical space systems and have created a working group to establish and implement an agency-wide space protection program. NASA built Landsat-7 for the U.S. Geological Survey; all inquiries regarding Landsat-7 should be addressed there.”
