SpaceX launches the first Block 5 version of its Falcon 9 rocket for the Bangabandhu Satellite-1 mission.

The space industry is in the middle of a widespread transformation, as the last decade has seen a number of young companies begin to seek to profit in an area where most of the money was made from military contracts or expensive communications satellites.

The estimated $400 billion space economy is still largely dominated by large aerospace and defense companies, serving government-funded interests. But investors say that's changing, with Morgan Stanley, Goldman Sachs, Bank of America and UBS each issuing frequent research for clients on how the space industry is growing. Wall Street's consensus is that space will become a multitrillion-dollar economy in the next 10 to 20 years — a view investors today are banking on.
