Validating the ds1 remote agent experiment


The DS1 mission was part of NASA’s New Millennium Program, a series of deep-space and earth-orbiting missions designed to test and validate 12 high-risk new technologies. Wesley Huntress, NASA’s Associate Administrator for Space Science, was to “enable these technologies to be used with greater confidence on scientific missions of the early 21st century.” DS1 was also designed to test an unofficial “13th technology”: the model-based code generation of the spacecraft’s system-level fault-protection (FP) software.

“There’s more than one way to do it.” I’ve been working with Asterisk for nine years, and this motto becomes more true with each release, each added feature, and each clever person who attacks a telecommunications problem with this incredibly flexible toolkit. Then, I typically point the person toward the first edition of this book, , and set him loose.

If a technology has something to offer, it won't stay in the trough of disillusionment, just as AI has risen to a new sustainable level of activity.

For example, Figure 2 shows that although AI conference attendance numbers have been stable since 1995, they are nowhere near the unsustainable peak of the mid-1980s.

I see Asterisk making deep inroads into the financial, military, hospital, Fortune 100 enterprise, service provider, calling card, and mobile environments. From the basic beginnings of a PBX that Mark Spencer coded in 1999, the Asterisk project, with the help of thousands of developers, has moved from simply connecting phone calls and has matured into a platform that can handle voice, video, and text across dozens of virtual and physical interface types.
