Space missions need to have a defensive component or economic benefit. With economic returns often uncertain, space programmes have tended to be led by governments, because only they can invest in programmes that have a long-term pay-off, whether economic or geopolitical. When it comes to saving humanity from an asteroid impact, Tyson stressed that rather than establishing colonies in space, we would be better to try to deflect the asteroid.

تحدث نيل ديغراس تايسون، عالم الفيزياء الفلكية، أن البعثات الفضائية تُطلق عادةً إما لأغراض دفاعية أو اقتصادية لتبرير غايتها. وفي غياب ضمانات العائد الاقتصادي بالنسبة إلى القطاع الخاص، تتولى الحكومات إدارة جميع برامج الفضاء لما تملكه من قدره على الاستثمار في برامج ذات عائد طويل الأجل، سواء كان لهذا العائد بُعد اقتصادي أو جيوسياسي. أما بالنسبة إلى الدعوة لبناء مستعمرات على سطح الكواكب الأخرى تحسبًا لأي دمار قد يحلّ بكوكب الأرض نتيجة تعرضه لاصطدام نيزك، قال تايسون إن تحويل مسار النيزك يظل هو الحل الأمثل في هذه المرحلة
