How it matters ? . Such missions are having specific objectives and costly and human life is at risk. One cant undertake missions for whims and ego and outcompeting other country.

We would advise all space mission capable countries to collaborate in expeditions and research by allocating separate tasks under one master plan. It is tax payers money they burn and where is need to send several missions form different countries
