How Gravity Assists Work


Published on Sep 25, 2017

Time to clear up some misconceptions and show how a spacecraft’s close encounter with a planet can change a spacecraft’s orbit and enable trajectories beyond its available delta-v. I specifically cover some of the math and look at the unusual trajectory employed by the OSIRIS REx mission.

Heat Shields – Things Kerbal Space Program Doesn’t Teach


Published on Dec 29, 2018

The science of Aerothermodynamics covers what happens during a spacecraft’s fiery flight through a planetary atmosphere as it sheds speed, converting kinetic energy into thermal energy. This represents a complex interaction between fluid mechanics, thermal radiation and chemistry. The engineering required to shield hardware against this intense heating is an equally complex multi disciplinary art. If you want to learn the math then this course offered an excellent overview: https://tfaws.nasa.gov/TFAWS12/Procee…

Graveyard Orbits Where Old Satellites Are Forgotten

When a satellite is designed these days it’s also important to think about what happens at the end of its lifetime, for more LEO satellites they’ll happily decay and fall into the atmosphere on their own. But there are many cases where this can’t happen, either because the spacecraft doesn’t have the fuel, or because the satellite is dangerous. For these, there’s a retirement home in the graveyard orbit.

Changing the World v Dark Forces of Corruption


QUESTION:

Hi Marty !

How can we really expect politicians to make any kind of decisions when even the best humans can only think of 2 MAYBE 3 aspects at a time…. let alone complex dimensions that your computer seems to be able to interpret so well. Are we due for a reality check in what the public should realistically expect from our “leaders”?

It seems that if politicians actually had some skin in the game like CEO’s and investors they might act differently?

Hope the weather is nice in Florida ! its raining as per usual on the west coast !

ANSWER: I really believe that creating a fully functioning AI computer that can answer the questions because it can see everything as a whole is essential for the complexity we live in. I have tried to do that in the field of economics, but there are dark forces that are trying very hard to prevent what I have spent my life trying to create. There are tremendous conflicts where people do not want change because it would end the gravy train. I am not naive. There are those who would love to kill me or conjure up a civil contempt again to imprison me until I die to shut me up. This is the world we live in. They will say anything to win and there is never a constitutional right that is worth anything to protect you. As I have written many times, they get to do as they like and it is always your burden to prove you have any human rights at all.

So I share this vision of an honest government that is really for the people and by the people. They are easy words to write or to say. So many people have died fighting for the true meaning of those words. The dark forces of corruption are powerful and very hard to overcome.

Why do cylindrical rockets roll?


Everyday Astronaut

Here’s a fun question that not only have I myself asked, but I get asked fairly often, why do we hear a call out like “roger roll” or “roll program complete” at which point we can see the rocket rotate or roll on its X axis… The best example of this was the Space Shuttle which had a very obvious and dramatic roll program. As soon as it cleared the tower, you can see it making a very impressive and sometimes scary looking roll. Now a maneuver like this makes sense when a vehicle is asymmetrical like the Space Shuttle, but why do cylindrical rockets like the Saturn V, Titan, Atlas, Delta IV etc etc even bother doing a roll? Can’t rockets just tip over in whatever direction they need to go? Do a little pitch here, a little yaw there just as long as the pointy end is going the direction it’s intended to go, who cares which side of the rocket is facing the Earth and which side is facing space… right? So today we’ll first define the pitch, yaw, roll and their corresponding axis on a rocket, then we’re going to dive into why a rocket rolls in the first place, take a look at launch azimuths and their relationships to trajectories and we’ll look at some unique solutions to orientations including some rockets that don’t roll on ascent to align with their trajectory.

World War III – 2024-2027?


QUESTION: Besides the Bible, there are many clairvoyants who predict that there will be World War III. Your models predict the rise in war tensions. What is your “opinion” about the prospects for a third world war?

JC

ANSWER: There is no doubt that we are in the process of a rising war cycle. It really appears to be more of a bitter war between leaders once again, as was the case with the last two World Wars. World War I was really about destroying the former Holy Roman Empire which had its seat of power in Vienna. That city was besieged in 1683 when the Ottoman Empire sought to conquer Europe. If you recall, the financial panics I used to discover the Economic Confidence Model began with the Panic of 1683 caused by the invasion of the Ottoman Empire.

The War Cycle is turning up and we are looking at a possible peak as early as 2027. This is why I have been concerned about the economic crisis in 2021-2022. Once the economy turns down, it will be the fuel for the war.

We must also respect that this particular cycle is the combination of both civil and international unrest. I do not believe we are in a cycle of conquest. Nobody wants to conquer and occupy each other — neither China, Russia, nor the USA. So, on the international level, it appears we are dealing with old grudges. When I have asked why Russia is our enemy since they abandoned communism, the only response I get is that, “Well, they are Russian!” World War I unfolded when the Archduke of Austria was assassinated by a Serb. He was heir to the throne of the old Holy Roman Empire. The French hated Germany for they were defeated under Napoleon. Additionally, in the first Treaty of Versailles in 1871 Germany became an empire at the expense of France. So it was really very much about settling old debts.

World War II was created by the oppression of the German people for the sins of their leaders. That led the German people to turn to Hitler because they were humiliated.

We would classify Napoleon and Hitler as warmongers of conquest. The Russian Revolution in 1917 and that in China led by Mao were class warfares instigated domestically that manifested into revolutions arising from civil unrest.

In Russia, the revolution really began in October 1905 when czarist troops opened fire on a peaceful group of workers marching to the Winter Palace in St. Petersburg to petition their grievances to Czar Nicholas II. Some 500 protestors were massacred on “Bloody Sunday,” setting off months of protest and disorder throughout Russia. It was 8.6 years later that World War I erupted in 1914. This signaled that there would be a rise in tensions 112 years later which would be 2017.

Vladimir Lenin was born in 1870 into a middle-class family in Ulyanovsk, Russia, but when he was a teenager, he became political after his older brother was executed in 1887 for plotting to assassinate Czar Alexander III. When he reached the age of 17, he was expelled from Kazan Imperial University for taking part in an illegal student protest. Then in December 1895, Lenin and the other leaders of the Union were arrested. Lenin was jailed for a year and then exiled to Siberia for three years. Upon his release in 1900, Lenin went to Western Europe. In 1902, he published a pamphlet entitled “What Is to Be Done?” Lenin argued that only a revolution would bring socialism to Russia by force. In 1903, Lenin met with other Russian Marxists in London and established the Russian Social-Democratic Workers’ Party. From the outset, Lenin’s Bolsheviks (Majoritarians) advocated violence and the Mensheviks (Minoritarians) advocated a democratic movement toward socialism. The split became official in the 1912 conference of the Bolshevik Party. If we use this as the start date, then we arrive at 2024 where we may see the sharp rise in tensions on a class warfare foundation worldwide once again. This may mark the culmination of the Marxist-Socialism movement that could end in blood in the streets once again.

Consequently, this World War III is more likely to be a combination of class warfare and settling old scores. The period of concern would be the 2024-2027 time frame from a cyclical perspective (sorry, no visions for I lack the clairvoyant ability).
