Looks like a dry run for the booster catch







SpaceX getting ready to catch that booster. They'll drop a dummy booster in a controlled drop onto the chopsticks in order to test the system.

The rest of the report is of no interest to me, but if you wish, you can watch all of it. It will join at the interesting point for me.

Nerdy calculations for Venus-sourced Tanker Fleet for Space Missions elsewhere







A new entry in this series, which will be part 4.

The previous post was here.







Consider the famous equation, E = mc^2. ( Yeah, I know. I should use a real exponent. Humor me.) If you were to apply algebra to the equation by multiplying it by a fraction. Let's say X, where X is the fraction of the speed of light that 1 km/sec of velocity is. Therefore, for any delta V of 1 km/sec, the delta-E ( where E=energy) could be calculated, or estimated depending upon how picky you are. Thus, delta-E would be equal to m * X^2.

What does this do for us? Well, I'd advance the notion that a rocket ship could carry a lot more mass once it is in orbit, than what it could carry in order to get into Low Earth Orbit (LEO). Looking at the equation, you will note that it takes a lot more energy to do delta-V than if you were to increase mass. That's because delta-V is exponential in terms of energy ( delta-E). You can increase mass a lot faster than delta-V.

That's why atomic bombs are so powerful. It only takes a small amount of mass in order to get a lot of energy. That's because the energy is coming from a large velocity yes, but also the energy is increasing exponentially with its speed. And the speed of light is really fast, and thus you get really big numbers.

We can use this to our advantage once we get into space. Just load up that Starship with a lot more than 200 tons, and you can make a crap load of methane gas and oxygen. You could fill up the tanks in Venus orbit, I'll bet. ( and then some)

Let's say a Starship masses out at 1000 tons fully loaded. ( I'm too lazy to look it up.) That's 5 times more than the 200 tons that it says its rated for in order to get to LEO. Going back and forth from Low Venus Orbit (LVO) would use a lot of fuel. But not if you can load up a lot more than you started with, because your delta-V was a lot less.

You could make big tanker ships in High Venus Orbit (HVO), and fill them up with a lot of fuel. A LOT OF FUEL. That's because of an even lower delta-V requirement in order to get to HEO from VHO.

Something to think about, eh?



7.75 ^2= approx. 60 60 million m/s ^ 2= times mass in kg

7^2= 49 49 million m/s ^ 2= times mass in kg

6 ^2=36 36 million m/s ^ 2= times mass in kg

5 ^2=25 25 million m/s ^ 2= times mass in kg

4 ^2=16 16 million m/s ^ 2= times mass in kg

3 ^2=9 9 million m/s ^ 2= times mass in kg

2 ^2=4 = 4 million m/s ^2= times mass in kg

Energy equals velocity squared @ 1 km/sec = 1000 m/s*1000 m/s = 1 million m/sec^2; = times mass in kg

Mining Venus, the Saudi Arabia of the inner solar system







A new entry in this series, which will be part 3.

The previous post was here.

The small delta-V requirements for a high Venusian orbit is rather low. The significance of this is in the energy requirements, as energy is most highly correlated with delta-V. This is according to the basic laws of motion, in which energy is related to velocity SQUARED. This makes energy an exponential function, as opposed to mass, which is linear.

In other words, we can transport large amounts of mass due to the low energy requirements due to the low delta-V it takes to get from high Venus orbit to high Earth orbit. Consequently, large propellant depots could be constructed, which would facilitate larger masses to be moved between the planets, including Mars.

If Elon Musk is interested in settling Mars, here's a golden opportunity to make that happen. You could construct space Arks, which would be necessarily HUGE in order to accomodate large numbers of people. His Starships could be tasked with getting his passengers to and from the Arks, which would only need a small amount of delta-V to get from high Earth orbit to high Mars orbit. The Arks would be tasked with dealing with the problems of a long journey through interplanetary space. They could be made so that they could resist the high radioactivity while spun up to provide artificial gravity. It would be like traveling the planets in a large ocean liner.

Arks could be lifted off the moon. The moon has a low delta-V requirement, which would also aid in moving large amounts of mass necessary for the construction of the Arks.

Venus has a lot of sulfuric acid and carbon dioxide. These can be mined from the upper atmosphere, which would save energy from having to dive deep into the gravity well. That concept was covered in the previous posts on the subject.

Sulfuric acid can be made into water by taking out the sulfur. Carbon dioxide and water can make oxygen and methane. These can power the Starships.

There is so much carbon dioxide and sulfuric acid on Venus that you'll never run out. Besides, there is plenty of other materials in the atmosphere of Venus that it could be a treasure trove for space mining.

2020 election was rigged

Also, the J6th riot was staged, and helped Brandon's installation as POTUS. Consequently, the Brandon years are not legit.
