Blue Origin, a spaceflight company founded by Jeff Bezos made headlines yesterday as it launched its flagship rocket ‘New Shepard’, a reusable vertical takeoff vertical landing (VTVL) rocket from its West Texas launch facility and landed it successfully back to earth without any issues.

As per the team associated with the launch, the rocket or the vessel reached at an altitude of over 100 thousand kilometers and retuned back on earth without any difficulties and technical issues.

The company said in a statement that success of their flagship rocket is a significant step in its quest to build a reusable spacecraft that could carry up to six passengers into space and bring them back on earth safely.

“Now safely tucked away at our launch site in West Texas is the rarest of beasts - a used rocket. Full reuse is a game changer, and we can't wait to fuel up and fly again”, Bezos said via a CNN Money article.

Although the success of the rocket made headline it failed to impress everyone. Tesla and SpaceX owner Elon Musk although congratulated the company for its success,they also gave some backhanded compliments and clarifications on the subject of space travel.

Musk said in order to reach space one needs ~Mach 3, but GTO orbit requires ~Mach 30, and the energy needed is the square, i.e. 9 units for space and 900 for orbit.

Thereis difference between the space and orbit, said Musk. Everything beyond the Karman Line is considered ‘outer space’. The New Shepard reached outer space, but did not reach the distance and energy requirements to go into LEO.
