It’s been hard to get a sense of what ARCA has been up to lately, and how seriously we should take this project. But this week, they released the first episode of a new series of videos leading up to their launch of a subscale vehicle powered by a linear aerospike engine.
They’re planning on launching Demonstrator 3 this August from Spaceport America. But I’ve yet to be able to find anything on whether or not they’ve done any engine firings, which is a bit perplexing. Generally, my interest isn’t piqued until I see some engine activity. Nonetheless, it’s good to see some hardware in the video, and to hear from people working on the project.
