United Launch Alliance Atlas V Rocket Launch Scrubbed

Lousy weather already has resulted in a pair of back-to-back launch delays.

There’s a 40 percent chance of weather good enough to permit a liftoff from Launch Complex 41 during a 30-minute window that closes just before sunset.

NASA is highly anticipating for its commercial cargo supply to be in transit again as two suppliers are grounded from the launch accidents that led to explosions in 2014, and now, the space station is in need of restocking supplies such as food and water.

With less than four hours remaining in the countdown, launch director Bill Cullen called off Saturday’s attempt to send an unmanned Atlas rocket soaring.

When the rocket does blast off, it will mark the 60th launch of an Atlas V rocket and the 30th launch of the rocket’s 401 configuration, but it’s the first time this type of rocket will ever launch a cargo ship to the International Space Station. But even the Atlas is no match for Mother Nature.

High winds and bad weather are keeping a cargo supply spacecraft from launching and reaching the International Space Station.

Mark Kelly is a retired astronaut as well as an author; his “Mousetronaut” and “Mousetronaut Goes to Mars” are among seven storybooks inside the Cygnus.

Expedition 45 Flight Engineers Kjell Lindgren of NASA, Oleg Kononenko of the Russian Federal Space Agency (Roscosmos) and Kimiya Yui of the Japan Aerospace Exploration Agency will undock their Soyuz TMA-17M spacecraft from the space station at 4:49 a.m. The crew members will land in Kazakhstan at 8:12 a.m. (7:12 p.m. Kazakhstan time).

It’s also the United Launch Alliance’s first-ever resupply mission to the orbital outpost. On board since March, he’ll be up there until the beginning of this coming March.
