credit: Flight / caption: Christy Hales presentation raised some important issues about Ares staging
At the 3rd International Association for the Advancement of Space Safety conference held in Rome this month NASA safety and reliability engineer Fayssal Safie and Bastion Technologies' Christy Hales talked about risk issues with the Ares rockets
Hales spoke about a study to examine the risk of fire from hydrogen and oxygen leaking into the interstage. I had reported about related work on this blog in August. Bastion's interstage work is continuing, the point during ascent when the risk is highest of an ignition is just before separation, which will see the use of pyrotechnics
Go through to the extended portion of this blog post to watch the presentations' videos
The first video with Safie's presentation and Q&A lasts for 31min and the second, Hales, is about 16min long. Due to technical problems the last few minutes of Safie's video lost audio
