BS ISO 24113:2011 pdf free download Space systems — Space debris mitigation requirements
1 Scope
This International Standard defines the primary space debris mitigation requirements applicable to allelements of unmanned systems launched into, or passing through, near-Earth space, including launch vehicleorbital stages, operating spacecraft and any objects released as part of normal operations or disposal actions.
The requirements contained in this International Standard are intended to reduce the growth of space debrisby ensuring that spacecraft and launch vehicle orbital stages are designed, operated and disposed of in amanner that prevents them from generating debris throughout their orbital lifetime.
This International Standard is the top-level standard in a family of standards addressing debris mitigation. ltwill be the main interface for the user, bridging between the primary debris mitigation requirements and thelower-level implementation standards that will ensure compliance.
This International Standard does not cover launch phase safety for which specific rules are defined elsewhere.

Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 9000:2005 and the following apply.3.1
approving agent
entity from whom approval is sought for the implementation of space debris mitigation requirements withrespect to the procurement of a spacecraft, or its launch, or its operations in space, or a combination of thoseactivities
EXAMPLE
Regulatory or licensing authorities; national or international space agencies.
3.2
break-up
event that destroys an object and generates fragments that are released into space
3.3
casualty risk
probability that a person is killed or seriously injured
3.4
disposal
actions pertormed by a spacecraft or launch vehicle orbital stage to permanently reduce its chance ofaccidental break-up and to achieve its required long-term clearance of the protected regions
3.5
disposal phase
interval during which a spacecraft or launch vehicle orbital stage completes its disposal actions
3.6
end of life
instant when a spacecraft or launch vehicle orbital stage is permanently turned off, nominally as it completesits disposal phase, or when it re-enters, or when the operator can no longer control it
3.7
end of mission
instant when a spacecraft or launch vehicle orbital stage completes the tasks or functions for which it hasbeen designed, or when it becomes non-functional or permanently halted because of a failure or because of avoluntary decision
3.8
geostationary Earth orbitGEO
Earth orbit having zero inclination and zero eccentricity, whose orbital period is equal to the Earths siderealrotation period
3.9
launch vehicle orbital stage
stage of a launch vehicle that is designed to achieve orbit
3.10
Launching State
State that launches or procures the launching of a spacecraft,or a State from whose teritory or facility aspacecraft is launched
NOTE This definition is consistent with the definition in the UN Liabllity Convention[5] and Resolution 59/115[6] of10 December 2004 on the notion of the Launching State.
3.11
normal operations
planned tasks or functions performed by a spacecraft or launch vehicle orbital stage prior to its disposal3.12
orbital lifetime
period of time from when a spacecraft or launch vehicle orbital stage achieves Earth orbit to when itcommences re-entry
3.13
probability of successful disposal
probability of successfully disposing of a spacecraft or launch vehicle orbital stage, evaluated as a conditionalprobability weighted on the mission success at the time disposal is executed
NOTESee Annex A_
3.14
protected region
region in space that is protected with regard to the generation of space debris to ensure its safe andsustainable use in the future
3.15
re-entry
process in which atmospheric drag cascades deceleration of a spacecraft or launch vehicle orbital stage (orany part thereof), leading to its destruction or return to Earth
NOTE For operational purposes, this is when the period of the mean orbit is 89 min or less.
3.16
regulatory authority
governmental entity,national or international,that bears responsibility for implementing space debrismitigation policy or law with respect to the procurement of a spacecraft,or its launch, or its operations inspace, or a combination of those activities
3.17
space debrisorbital debris
man-made objects,including fragments and elements thereof,in Earth orbit or re-entering the atmosphere,that are non-functional
3.18
spacecraft
system designed to perform specific tasks or functions in space
NOTE A spacecraft that can no longer fulfil its intended mission is considered non-functional.Spacecraft in reserveor standby modes awaiting possible reactivation are considered functional.
