XNU [SEP] programming language
developed at Carnegie Mellon University with components from 4.3BSD and an Objective-C API for writing drivers called Driver Kit.
After Apple acquired NeXT, the Mach component was upgraded to OSFMK 7.3 from OSF, the BSD components were upgraded with code from the FreeBSD project, and the Driver Kit was replaced with a C++ API for writing drivers called I/O Kit.
Kernel design.
XNU is a hybrid kernel, containing features of both monolithic kernels and microkernels, attempting to make the best use of both technologies,
of the origin of Earth's water. The lead is Colin Snodgrass, from The Open University in the UK. "Castalia" was proposed in 2015 and 2016 to the European Space Agency within the Cosmic Vision programme missions M4 and M5, but it was not selected. The team continues to mature the mission concept and science objectives. Because of the construction time required and orbital dynamics, a launch date of October 2028 was proposed.
