    A Viking lander being prepared for dry heat sterilization – this remains the "gold standard" [1] of present-day planetary protection.. Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions.

  7. Space exploration - Wikipedia

    en.wikipedia.org/wiki/Space_exploration

    Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...

    en.wikipedia.org/wiki/Space_debris

    Fortunately, the current space exploration is not completely driven by competition, and there still exists a chance for dialogues and cooperation among all stakeholders in both developed and developing countries, to reach an agreement on tackling space debris and assure an equitable and orderly exploration. [247]

  9. Space sustainability - Wikipedia

    en.wikipedia.org/wiki/Space_sustainability

    The space field should be used peacefully, jointly protect the space field from harm, and maximize space utilization through environmental, economic, and security exploration of space. [16] These consensuses also clarify the relationship between space sustainability and international security, that states and individuals explore space for ...
