United Launch Alliance's (ULA) Delta IV Heavy rocket is expected to loft a secret payload to space for the National Reconnaissance Office (NRO) at 1:51 p.m. ET Saturday.

You can watch a webcast of the launch starting at 1:31 p.m. ET directly through ULA. (The ULA webcast isn't available for embed at the moment. This story will be updated if it becomes available.)

As of this writing, the chance of good weather during the launch is 60%.

The only information released by ULA about this secretive mission -- called NROL-37 -- is that it's "in support of national defense," according to a mission listing.

The webcast itself will probably be pretty short. According to the space industry website Spaceflight Now, the live broadcast will cut off about six and a half minutes into the launch, going into a news blackout to keep the secret mission secret.

While not much is known about the mission itself, the NRO was pretty upfront about what their (kind of creepy) mission patch for the payload represents.

According to a Facebook post from the NRO, the knight represents "a symbol of courage with a chivalrous code of conduct representing bravery, training, and service to others."

"The knight stands in front of the U.S. flag in a defensive posture as to protect at all cost," the NRO continues. 

"The eagle on the chest is a symbol of both freedom and the United States of America. The sword is a message of tenacious, fierce focus with the claws representing extreme reach with global coverage."
