Earth-Observing Satellite Launch Delayed by Wildfire, Ground Leak
An Atlas V rocket carrying an Earth-imaging satellite will not launch until Sept. 26 at the earliest, after two incidents delayed its scheduled launch last week.
The WorldView-4 satellite was originally scheduled to launch from Vandenberg Air Force Base in California on Friday (Sept. 16). That launch was delayed due to a "minor ground leak during propellant tanking," according to contractor United Launch Alliance's Twitter account. The launch was rescheduled for Sunday (Sept. 18) but was delayed again, this time to a wildfire that began burning at the southern end of the base on Saturday (Sept. 17).
Now, United Launch Alliance has announced the launch will take place no earlier than Sept. 26, due to availability of the Western Range (the name of Vandenberg's space-launch range). The launch window will open at 11:30 a.m. PDT (2:30 p.m. EDT/1830 GMT).
The wildfire is still burning and has charred about 4,500 acres, according to the Los Angeles Times. Access to the South Base is limited to "mission essential personnel," according to the 30th Space Wing (Vandenberg Air Force Base) Facebook page.
The WorldView satellites are some of the most powerful commercial Earth-imaging satellites in the world. Like its predecessor WorldView-3, the WorldView-4 satellite can resolve objects as small as 1 foot (31 centimeters) from space. The satellites are built by Lockheed Martin Space Systems Co. and operated by DigitalGlobe.
