A SpaceCraft Could Get to 430,000 Miles From the Sun Using Proposed Coating

• https://www.nextbigfuture.com, brian wang

Researchers think a new coating could allow spacecraft to get close as one solar radii (430,000 miles) from the Sun's surface. This would be eight times improvement over the Parker Solar Probe.

The goal of a Phase 1 NIAC study is to determine how near a spacecraft might come the Sun using a novel, very high-reflectivity coating. Using this material to cover a thin solar shield and including a secondary silvered reflective cone between the shield and the spacecraft (to reflect away infrared radiation from the shield).

The Parker Solar Probe utilizes a solar shield comprising a lightly-coated carbon composite layer on top of four inches of carbon foam. However, the temperature limits of the shield restrict the closest approach distance.

urrently have co-funding to demonstrate that our new coating can allow a coated tank to reach cryogenic temperatures at earth distance from the Sun. This funds allow for continued coating development for our proposed Phase 2 NIAC to consider only coating issues relevant to being near the Sun. Specifically the optical and mechanical issues related to high temperature long-wave reflectors will be an area of study in our Phase 2 effort.

Who cares? It’s a moot point, we’ve never transverse the Van Allen radiation belts. We have not sent a human to the moon or anywhere else above 100 mi in space, the ISS & all satellite activity has been in this 100 mi circumference. A paper detailing this problem was written by Russians a few years ago, so far it hasn’t been solved, the Russian & others claiming moon landing are false to, they realized the US made phony claims they couldn’t reveal, so they capitalized. To cross these belts a minimum of 7” of lead is require to shield astronauts from Gamma radiation in flight, the rocket has not been made to push a lead lined capsule to the moon. Passing thru the Van Allen belts, NASA says a man would receive 150 joules one way, a round trip would have them absorbing 300 joules, a fatal dose, stop believing the Talking heads of NASA, they lie with phony authority, do your own “due diligence” THINK!
