In a letter to Congress a year ago, Defense Secretary Jim Mattis opposed the creation of a new military branch and cautioned against creating "organizational layers at a time when we are focused on reducing overhead and integrating joint warfighting functions".
· The formation of an elite group of war fighters called the Space Operations Force. "Space is an environment that we're supposed to work together peacefully in".
The White House points to galactic threats from USA adversaries, particularly Russian Federation and China, which could develop weapons to jam, blind or destroy satellites that are crucial to communications systems.
Former astronaut and retired U.S. Navy Captain Mark Kelly on Thursday said that while Pence was right about the threats in outer space, the military was already handling them. With migrant children still being separated from their parents at the border, the devastation of agricultural industries from the trade war with China, and the threat of white nationalism looming, "Space Force" has become the new cover-up to the administration's injustices.

The plan would increase the visibility of efforts to defend satellites from attack and other space-related tasks. But these operations are spread across the Air Force, the National Reconnaissance Office, and the Army.
He said the countries "have been conducting highly sophisticated on-orbit activities that could enable them to manoeuvre their satellites into close proximity of ours, posing unprecedented new dangers to our space systems".
Opinions on the Space Force in Congress have been divided.
At present, the US Air Force Space Command looks after space power and air force cyberwarfare.
In March this year, Mr Trump's National Space Strategy was said to recognise USA "competitors and adversaries have turned space into a warfighting domain".
"Men and women of the [DoD] have pioneered the most groundbreaking discoveries that have literally revolutionized space in our hours of need", he said.
Defense Secretary Jim Mattis has endorsed steps to reorganize the military's space warfighting forces and create a new command, but has previously opposed launching an expensive new service.
A Space Development Agency will be charged with developing and fielding new capabilities, and a single civilian authority - the assistant secretary of defense for space - who will oversee the branch and report on the force's growth and expansion to the Defense secretary.

Other people such as Ricky Gervais suggested the move is intended as a distraction from the Mueller investigation, while Chelsea Handler called for Fox News host Laura Ingraham should be sent up to space as part of the program.
