  • PicoIDE - A Journey Into Understanding the IDE Bus

    While looking at all these standards, something caught my eye: the technical editor for several versions of them had a work address just a couple doors down from where I worked! It was an old office of Maxtor, which came out of the acquisition of the ill-fated MiniScribe. As it turns out, this area of Colorado had a large part in the development of storage technology and still does: Maxtor was acquired by Seagate which still maintains an office here. In any case, I had to make a mini-pilgrimage and take a selfie in front of the nondescript building in an industrial park where the standards I had been poring over were written.

  • NASA hit by fuel leaks during a practice countdown of the moon rocket

  • NASA acknowledges the elephant in the room with the SLS rocket

    If NASA were really going to do the best it could with this rocket, there were options in the last three years. It is common in commercial rocketry to build one or more “test” tanks to both stress the hardware and ensure its compatibility with ground systems through an extensive test campaign. However, SLS hardware is extraordinarily expensive. A single rocket costs in excess of $2 billion, so the program is hardware-poor. Moreover, tanking tests might have damaged the launch tower, which itself cost more than $1 billion. As far as I know, there was never any serious discussion of building a test tank. Hardware scarcity, due to cost, is but one of several problems with the SLS rocket architecture. Probably the biggest one is its extremely low flight rate, which makes every fueling and launch opportunity an experimental rather than operational procedure. This has been pointed out to NASA, and the rocket’s benefactors in Congress, for more than a decade. A rocket that is so expensive it only flies rarely will have super-high operating costs and ever-present safety concerns precisely because it flies so infrequently.

    Until this week, NASA had largely ignored these concerns, at least in public. However, in a stunning admission, NASA’s new administrator, Jared Isaacman, acknowledged the flight-rate issue after Monday’s wet-dress rehearsal test failed to reach a successful conclusion. “The flight rate is the lowest of any NASA-designed vehicle, and that should be a topic of discussion,” he said as part of a longer post about the test on social media. The reality, which Isaacman knows full well, and which almost everyone else in the industry recognizes, is that the SLS rocket is dead hardware walking. The Trump administration would like to fly the rocket just two more times, culminating in the Artemis III human landing on the Moon. Congress has passed legislation mandating a fourth and fifth launch of the SLS vehicle.
