European Space Agency.
Nearly three months since the initiation of the Selene Project, Italy and France had a hard time lobbying the other nine countries, but they finally made some achievements.
Apart from them, Spain, Germany, Germany, Henan, Norway, and Switzerland expressed positive support, willing to contribute money and technology, while the rest of the countries were mainly wavering.
In fact, the UK was the biggest target of their efforts, but the UK's economy was not doing well at the moment, and even though they were very interested in the Selene Project, they were quite worried about the European Space Agency's execution abilities.
After all, the European Space Agency is not a Union government entity and could not ensure that the plan would be carried out with ironclad enforcement across the nations, leading to too many uncertainties.
