	COLUMBUS is the biggest project being carried out by ESA. It is a
joint programme with NASA's Freedom space station Project. The objective
of COLUMBUS is the development of the european part of the space station.

	COLUMBUS' software must be written in Ada, and HOOD must be used as
design methodology. C or Assember may be used in special circumstances. 

	There are software standards for COLUMBUS (ESA reference STD 
12131800 000; Issue 2; 15th November 1988), that cover:

		- software life cycle
		- documentation format
		- SADT
		- HOOD
		- Petri Nets
		- Detailed Design
		- software qualification
		- prototyping
		- Data Design Standard
		- software coding standards (Ada, C, Assembler and Command
		  Languaje)
		- software product assurance
		- commercial software procurement
		- configuration management
		- PDL 

	We are not sure about the use of Ada in other ESA projects, but it
seems that Ada is the current baseline.
