LIVE Blog: Boeing Starliner OFT-2 Launch
Today’s Atlas V launch with Boeing’s Starliner spacecraft has been scrubbed. The launch will be attempted tomorrow August 4th.
9:34 am CT Status Update: The launch will conduct a 24 hour recycle. This means that the launch will be attempted tomorrow August 4th at around the same time. When we have more information we will update.
9:29 am CT Status Update: Today’s launch has been scrubbed. Will update this blog when we have more information.
9:21 am CT Status Update: The Atlas V launch countdown has entered a planned 4 hour built in hold. This hold allows controllers time to work any issues that may come up. So far the launch vehicle and Starliner are doing great! The weather forecast for todays launch remains acceptable. No threat of lightning is expected. Chances today remain 50/50.
Fueling of the Atlas V rocket has been completed as well. The Centaur second stage is also fueled and ready to go.
Today’s flight test will demonstrate performance capabilities of the Atlas V Guidance Navigation & Control systems as well as docking, re-entry and landing operations. The Atlas V will deliver Starliner spacecraft into an initial 98 nautical mile sub-orbital trajectory before Starliner’s own engines will burn, taking it the rest of the way to orbit and toward the International Space Station.
This is Boeing’s second Orbital Flight Test mission. Its first mission was cut short due to an internal mission timer anomaly on Starliner. Quick action from ground controllers placed Starliner into a lower but stable orbit. After checking over Starliner systems, NASA and Boeing decided to cancel rendezvous and docking with the Space Station. Although its mission was cut short. Starliner was able to demonstrate better than nominal performance during launch, orbital flight, reentry, and landing.
Today’s flight, Orbital Flight Test – 2 (OFT-2), is expected to fly a full mission profile. Testing Starliner systems from pre-launch to docking, undocking, landing and recovery. Starliner will execute a number of demonstrations on its way to the International Space Station. Examples include its ability to hold docking attitude, receive commands from the ISS, and command holds and retreats during final approach. Once docked Starliner will undergo a number of checkouts like charging the batteries, transferring files through Station for downlink, transferring cargo, and opening and closing the hatch.

I’m a tiny bit obsessed with space. I’m told it’s an acceptable obsession because I take what I learn and share it with others. If I’m not writing about space, among other things, I’m busy doing science with one of the many student orgs I volunteer with or, advocating to bring more STEM programs to underrepresented students. I miss working in a lab, so invite me out to see yours!
