Case of Envisat
• configuration:10m x 5m x 26m
weight: 8 tons
• 2002 - launched by ESA
• April 2012 - lost communications link
• May 2012 - ESA declared Envisat’s end-of-mission

• “a huge problem that will not go away
for about 150 years”
• “Lowering Envisat to an orbit that
would allow reentry within 25 years,
however, was never an option because of
its design and limited amount of
fuel”——ESA

a. Article IX of the OST:
![Page 12: Legality of Non-Cooperative Satellite Removaliaassconference2013.space-safety.org/.../1120_Li.pdf · Russia National Standard GOST, R 52925, (2008) U.S: General Requirements to Spacecraft](https://reader033.vdocuments.us/reader033/viewer/2022051512/603abc0a908fea37f90d4084/html5/thumbnails/12.jpg)

• ‘harmful contamination’ is a
generic referring expression

b. Space debris mitigation Guidelines
• Guideline 6: Limit the long-term presence of
spacecraft and launch vehicle orbital stages in
the low-Earth orbit (LEO) region after the end
of their mission
• Guideline 7: Limit the long-term interference
of spacecraft and launch vehicle orbital
stages with the geosynchronous Earth orbit
(GEO) region after the end of their mission

• “agree that the voluntary guidelines reflect
the existing practices developed by a number
of national and international organizations.”
• a legally non-binding set of guidelines was
not sufficient and that the Committee should
do more to stress the importance of the
guidelines in promoting the safe and peaceful
use of outer space.

appropriate measures for this purpose.

Morally unacceptable harm:
• 1) threatening to human life or health, or
• 2) serious and effectively irreversible, or
• 3) inequitable to present or future generations,
or
• 4) imposed without adequate consideration of
the human rights of those affected.

Scientifical Plausibility
• scientifical uncertainties
• the plausibility shall not be affected by the
time the hazards will happen, by saying
“however far off it might be, is not thereby
any less certain and inevitable.”
