Nasa Astronauts Bob and Doug Returns To Earth – SpaceX

SpaceX has safely returned Nasa astronauts Bob and Doug back to earth, on a historical mission that lasted for 64 days.
SpaceX is a privately owned company by Tesla CEO Elon Musk. SpaceX designs manufacture and launch advanced rockets and spacecraft.

The company was founded in 2002 to revolutionize space technology by using a reusable rocket and launch system to significantly reduce the cost of space flight.

On Sunday afternoon, the Dragon spacecraft hit the earth’s atmosphere at 27354 km per hour, heating the ship to more than 1926 Celsius. Hitting the atmosphere at that speed feels like a minor car wreck, according to the NASA commentators.

Musk’s company SpaceX is currently the only rocket-maker to use reusable vehicles, one reason it has dominated the commercial market.

Elon Musk tweeted that only when space travel becomes as common as air travel is when the future of civilization will be assured.

Why Humanity Must Become a Multi-Planetary Species

As early as 2040, Musk hopes to have thousands or tens of thousands of people living in a city-like colony on Mars. From there, he hopes to continue to increase the colony’s size until it exceeds one million people, at which point he believes there will be a sufficient number of people to “recreate the entire industrial base,” resulting in a sustainable civilization on Mars.

Musk and SpaceX hope to create the first city-like colony on Mars by the year 2040. In a supremely fascinating interview with Aeon, Musk said the following of his plans:

“I think there is a strong humanitarian argument for making life multi-planetary, in order to safeguard the existence of humanity in the event that something catastrophic were to happen, in which case being poor or having a disease would be irrelevant, because humanity would be extinct. It would be like, ‘Good news, the problems of poverty and disease have been solved, but the bad news is there aren’t any humans left.’”

Elon Musk

“Not everyone loves humanity. Either explicitly or implicitly, some people seem to think that humans are a blight on the Earth’s surface. They say things like, ‘Nature is so wonderful; things are always better in the countryside where there are no people around.’ They imply that humanity and civilization are less good than their absence. But I’m not in that school. I think we have a duty to maintain the light of consciousness, to make sure it continues into the future.”

Elon Musk.
