‘Star Wars’ Returns: US Military to Develop Space-Based Missile Defense System

(ANTIWAR.COM) — In what looks to be a highly ambitious and even more highly cost prohibitive scheme, President Trump has announced his intention to greatly expand US missile defense systems, with a major focus on putting them in space.

During his announcement Thursday at the Pentagon, Trump set out his goals, saying that he wants “to ensure that we can detect and destroy any missile launched against the United States – anywhere, anytime, anyplace.”

The Pentagon has had space-based interceptors on its wish list for some time, but between that and drones with lasers on them, they were far short of the sort of total, planet-wide coverage that President Trump is talking about.

A space-centric missile defense system must inevitably draw comparisons to the Strategic Defense Initiative, commonly called Star Wars, of the 1980s, a controversial and hugely expensive program that also sought space-based interceptors.

The timing of President Trump’s announcement will likely raise eyebrows on a few fronts, as it comes just a day after the US announced its intentions to withdraw from the Intermediate Nuclear Forces (INF) Treaty with Russia, and just a day before North Korean officials are to arrive to meet with the secretary of state.

Especially with respect to Russia, US buildups of missile defense systems have been met with major suspicion that the US is trying to eliminate Russia’s deterrent capability, a concern which often leads to Russian threats of a new arms race. With a treaty having just collapsed, that’s an even bigger concern this time.

This also likely is tied to President Trump’s long-standing fondness for militarizing space, and his attempts to create a Space Force. During his speech, Trump declared space to be a “new warfighting domain.”

Scientific American警告太空垃圾威脅衛星和地球; 再多為5G而設的約2萬枚衛星已計劃好了
Scientific American Warns Space Junk Threatens Satellites and Earth. Approx. 20,000 More Satellites for 5G Already Planned

According to Scientific American, “Relentless Rise of Space Junk Threatens Satellites and Earth”

Space is vast. Yet Earth orbits are becoming increasingly littered with debris (speckled graphic). A satellite could be demolished if struck by a 10-centimeter piece of junk, about the size of a softball. Even a one-centimeter tidbit could disable a spacecraft. And the more functioning, defunct or fragmented objects up there, the more that decay in the atmosphere (pink stripe). The collision problem has become so serious that in 2016 the European Space Agency (ESA), which tracks the objects, announced it might capture derelict satellites in low orbits, starting in 2023. Clutter is rising fast as more countries and companies launch electronics. In February 2017 India sent 101 shoebox-sized “cubesats” into a low orbit on a single rocket.

Most would agree then that blasting up to 20,000 additional satellites into space to aim 5G at Earth will undoubtedly making an already dangerous situation much worse.

In fact, anything emitting 5G wireless radiation on Earth and in space is unnecessary, harmful, and dumb.  Make it stop.
