Space Science has opened new objective, vision and mission for the humanity, but it is still dependent on the financial contributions from Government and wealthy. Good work has been done in harvesting renewable energy and power savings through better battery technology. But still lots of work has to be done. Space Mining is good, but that should not disturb the gravitational balance. Moon has an important role on the current position of planet Earth. So what will be the limit/checks for Moon mining in future. Increasing Space debris is also a problem.
