“No need to go there, we've already been there,” said President Trump. Nevertheless NASA insists that with the new ORION rocket we shall be there in about 2024 in order to repeat the landing 50 years ago.

The new Orion space craft is built using a much more powerful engine in order to bring astronauts into outer space.

Here is some data of the cone-shaped crew capsule weighing 22,000 pounds, 16 feet in diameter, and 10 feet high. The interior has a volume of about 345 cubic feet and measures about 10 feet in diameter to house between 3 and 5 persons.

The biggest challenge facing the crew is the Van Allen Belt of high intensity radiation stretching between 400 and 36,000 miles above the earth. The belt consists of trapped energized electrons coming from the sun and cosmic rays, having energy levels between 300,000 and 10 million volts, with bursts that can exceed 500 million volts. Note that a typical X-ray exhibit only 100,000 volts and one is exposed for only seconds. In contrast, it takes up to one hour to pass through the inner and outer belts, assuming a rocket speed of 26,000 miles per hour. The radiation intensity is so high that all electronic gear has to be heavily shielded otherwise it would be destroyed instantly.

In 1946, Van Allen discovered the belts (named after him) using a captured German rocket. He warned “in the end, I wonder if the huge national commitment — and the potential loss of live is really justified.”

In order to properly shield the crew from such radiation, it would take a lead wall liner about 5 inches thick. However, that is impractical since an inner wall of only 1-inch thick of lead weighs already 35,000 pounds! The former Apollo Capsules only had an outer layer of 0.188” thick aluminum followed by the same thickness of aluminum in the inside; hardly any shielding at all.

One way to reduce the time of radiation exposure is for the rocket to circle half way around the globe so that when the altitude approaches 400 miles the rocket will be above the south pole where the Van Allen Belt is much thinner. This could reduce to time to pass the Belt to less than 30 minutes.

One wonders could the radiation problem be the reason why Russia and China never attempted to land a man on the moon. Both countries certainly have the means to do so.

Manned space stations and satellites typically stay at an altitude below 200 miles and therefore avoid dangerous radiation. However, one astronaut while circulating the earth came close to the Van Allen Belts and noticed sparks in his eyes.

For reference, an airport scanner with an energy level of 100,000 volt will give you a radiation dose of 5 MSv which is considered harmless, due to the short duration. However an exposure of 10 minutes at this rate could give you cancer.

Here is a tip for my "green" friends: Any wind turbine in its twenty year lifetime cannot generate enough electricity to pay for it and its infrastructure.

A few issues back I asked you to tell your Congressmen to pass a law to make it illegal to connect internet cables to machinery in order to prevent installations of viruses into power plants and similar places. Well, you must have done something good, since Congress now formed a committee to study the problem. Let’s just hope the study shows results before World War III starts.

Dr. Baumann has published manuals on valves and was a contributor to many works including the "Instrument Engineers' Handbook" and the "Control Valves Handbook." He has also published several books on business management and German history, including "Hitler's Escape," which suggests that Adolf Hitler did not commit suicide and survived World War II. In his latest book, "Atomic Irony" he proves that the Hirshoma Atom Bomb contained captured German Uranium. For more of his reports, Go Here Now.
