Key takeaways

  • China is now a global space power, and notably the only nation besides the US to have successfully landed a rover on Mars and made it move.
  • However, further investment is still needed to compete with the US: China’s budget for space activities as a whole is $20bn.
  • While private players are an asset in space strategies, most Chinese players are heavily subject to state control and political decisions.
  • China is currently seeking to prioritise the use of resources on the Moon, using ISRU (In Situ Resource Utilisation) to contribute to the operation of its facilities.
  • Today, China has clear objectives: to send a Chinese citizen to the Moon, to set up a scientific exploration base, etc.

Key takeaways

  • In total, five conventions and their principles currently constitute a solid legal foundation, accepted by all and whose authority is so far undisputed.
  • The Outer Space Treaty prohibits sovereignty claims by a State, but it says nothing about private property.
  • The Artemis Accords are a legal instrument whose signature conditions the cooperation of States with the United States and sets forth a set of new principles among which private property in space is inscribed.
  • The adoption of international technical standards is essential to the development of space activities and equipment interoperability.
  • Officially, space is not a ground for hostilities although it is already heavily militarised – particularly with surveillance satellites.

Director of Strategy at CNES

Key takeaways

  • Today, European space industry is well developed both in the field of launchers and satellites and in space applications.
  • Compared with major players in the sector – namely the USA – Europe’s space industry is rather fragmented so must defend its strategic autonomy and strengthen its capacities.
  • Europe also suffers from a lack of private funding in the space sector.
  • Around 40% of the European space industry's turnover comes from the commercial sector, a much higher percentage than in the United States.
  • Europe has the potential to keep its place as a major global space power thanks to an excellent education system, high-performance industries, etc.
