Thanks a lot for your comment @hardaeborla. I am glad you read my post. 

> Hmm... I can really sense why Elon Musk and Jack Ma are always into competition when it comes to utilizing technology to engage in more technological advancement.

I have known Elon to always compete with Bezos, seeing that he and Jack are in competition is very funny because Jack Ma isn't visible in the Tech space, he doesn't really have a voice in the tech and space industry maybe because the Chinese government want to take the glory.

>We all recognize the fact that Elon Musk is now using SpaceX to engage in asteroid mining which itself can make you very rich and it seems the company are really doing a great job about this.

Space asteroid mining is nowhere close to Being operational currently, Mining Asteroid resources is not as easy as going to the ISS, it is very complicated and currently, they are still developing tools which can be used to mine the asteroid and to get to the asteroids without missing them since they spin and move fast since they aren't big.

> I won't be surprised if NASA starts loosing some of their staffs to private companies like SpaceX if the pay is much more than what they earn.

This can never happen, SpaceX is on a contract by NASA, which means currently,  NASA is employing SpaceX to do things for them. NASA goes beyond flying to space, they are responsible for keeping our planet safe from planetary and space bodies. They are responsible for monitoring all the Telescopes,  satellites and other equipment and tools in space and on earth, they are responsible to monitor the ISS as well as other planet. So people in NASA have a lot of work to do which are fun to take part in.
