Dear generous supporters,
For the last several months, you've heard me talk about getting to 1% of my subscribers being Patreon members.
I'll be able to really take this channel to the next level if we get there.
Since then, we've reached about 45% of that goal, but I don't see us crossing the finish line unless I have A LOT to offer in return.
So here's my proposal:
If we can reach 90% of that goal, REVENUE WISE, I'll start a channel EXCLUSIVELY for Patreon supporters. That means one recorded video and one Livestream per week, just for you! No one else will have access to this content.
Ever.
We can reach this goal, WITH YOUR HELP!
What does this mean for KZbin Members?
If my current KZbin Members join Patreon at the $3 level, and if my existing Patreon supporters bump up their support by ONE LEVEL, we can reach this goal this month!!
In addition, I will take video topic suggestions from you guys every week, and pick a video topic for the week.
That means you guys choose the content!
PLEASE NOTE THAT ALL CURRENT BENEFITS FOR KZbin MEMBERS WILL NOT CHANGE, WHETHER WE REACH THE GOAL OR NOT!
What do you think?
If this sounds like a fair deal, here's my Patreon link:

This is the kind of content that makes your channel shine. There are so many ideas that just haven't gotten the funding until lately. The post Apollo pullback really killed our innovation in propulsion. I am glad that we did finally perfect the ion engines from the 1960s. But high thrust efficient engines kind of died when the NERVA program was cancelled. Thank Nixon for his lack of vision and the "lets spend money on Earth" people in Congress. (As I always say, the idea that money will not be spent on something you don't want, does not guarantee the money will be spent on what you do want. And Space technology always boosts the economy, delivering $10+ of benefit for every dollar spent, and continues to pay in technological advancement for decades.)

[@frankmcgowan9457]

Starship using the atmosphere to slow itself is a design feature. The "belly-flop" is done to reduce its cross-sectional density to increae passive speed loss to reduce the amount of propellant required for this phase.

[@AdrianBoyko]

Reduce? Density?

[@frankmcgowan9457]

@@AdrianBoyko Yup. Passive speed loss can be managed by reducing the amount of mass per square meter presented to the atmosphere as the ship passes through it. The Starship is basically a cylinder 9m in diameter, 50m long having a dry mass of 100 tonnes, a payload of 100 tonnes and no more than 300 tonnes of fuel (25% full) for a total of 500 tonnes or 500,000 kg. Its end-on cross sectional density is mass/cross sectional area or 500,000 kg/63.617 m**2 = 7,859.5 kg/m**2 Forward or backward, that much sectional density will keep its speed until thrust is used. If it does the belly-flop, it presents a cross section of up to 9m x 50m or 450 m**2 if the vehicle is pitched up 90°. The flaps are mostly intended to manage that pitch up angle. It's sectional density is now: 500,000 kg / 450 m**2 = 1,111.1 kg/m**2 That is about 1/7 of the sectional density when presented end-on and even the extremely thin Martian atmosphere can slow the craft somewhat. The landing burn will start at a lower velocity and save fuel because less delta-v will be required. All we've done is rotate the ship 90° on its pitch axis, thereby reducing the sectional density by a factor of 7 and the atmosphere will save us fuel.

[@kennethferland5579]

Thing is an object dose not naturally assume that kind of orientation, a tube wants to naturally enter end first, heavy end first if it has one. It remains to be seen if StarShip has the control nessary to orient itself durring entry.

[@frankmcgowan9457]

@@AdrianBoyko Yes. Reduce its density. Specifically, reduce its cross sectional density relative to its direction of travel through the atmosphere. Starship's dry mass is 100,000 kg. It's payload is another 100,000 kg. If it arrives at Mars carrying 25% fuel, it will have 300,000 kg of fuel onboard for a total of 500,000 kg Starship is basically a right circular cylinder of a 9 m diameter and 50 m length. Its cross sectional area, perpendicular to its longitudinal axis is 3.1416 x 4.5m**2 = 63.617 m**2 Its cross sectional density is then total mass/area or 500,000 kg/63.617 m**2 = 7859.5 kg/m**2 If the ship pitches up 90° relative to it's path through the atmosphere, its cross sectional area will be 9 m x 50 m= 450 m**2 The mass remains the same, 500,000 kg, so the cross sectional density is 500,000 kg/450 m**2 = 1,111.1 kg/m**2 The belly-flop will make the atmosphere, any atmosphere, seven times more effective slowing the Starship without burning fuel.

[@frankmcgowan9457]

@@AdrianBoyko I have replied at length four times but they keep disappearing. The mass of the Starship will be the same, end-on or belly flop. However, the area being pushed through the atmosphere in the belly-flop is seven times the area of the base of the Starship. The belly-flop will cause the ship to slow seven times as much as boring straight in.

[@getinthespace7715]

They could pre-ship extra fuel and supplies before they sent explorers. That way they could make sure they had everything they needed arrived before they people landed. No unforeseen disasters because one of the necessary supply modules failed to make the trip intact. They could also take longer to get there vs a manned module.

[@EveryoneWhoUsesThisTV]

Yes, pre-shipping supplies is quite easy too.... They can be sent by Ballistic Capture, which requires no arrival burn or engine of any kind once launched. It can also be launched in a wider variety of launch windows, most of the year round. Your gear is just waiting for you in orbit when you arrive. But it takes around a year to get there so forward planning is required (as always in space missions)

[@wskinnyodden]

Hmmm, this would be nice IF we manage to get enough energy to have the pulse rates be in hertz, instead of minutes per pulse, so something like 100hz or 100 pulses per second would be a nice start...

[@kennethferland5579]

I've been saying for years that NASA should be investing in Electrical propulsion systems, the technology exists and we just need to scale it up into a large propulsion bus with multiple nested HALL thruster paired with large Solar arrays, the Lunar Gateway already features such a system at the largest scale we have so far achived and it's massing something like 20 tons. The technology is on the cusp of being ready for 100+ ton payloads and manned flight out to near Earth Asteroids which are going be a stepping stone to any longer duration beyond CisLunar mission. The Specific Impulse/thrust tradeoff can even be tuned and can easily hit 5k range and can produce trips to Mars in the range of 6 months but with twice the payload of conventional rockets. This is far better then any nuclear thermal concept, and while this pulsed nuclear concept looks superior due to high thrust the development cost would be far far higher then just continuing Solar Electric propulsion untill it's atleast reasonably exhausted of potential. And this pulsed nuclear plasma concept requires many many electrical support systems similar to what electrical thrusters need so you would be laying the foundationf for it, once HALL thrusters are perfected the next move is to go for a en.wikipedia.org/wiki/Magnetoplasmadynamic_thruster which ramps up the power and thrust levels still further.

This would always be my plan, if i were to create a mission to Mars. Create some sort of first stage with a more efficient form of propulsion (some form of nuclear propulsion, like fission or fusion, or something like this, as long as it (significantly) decreases the overall travel time), call it an MTS (or Mars Transfer Stage), and attach a (refueled ?) starship to it (which would become the second stage), to decrease the travel time, and in doing so, decrease the risk to the crew on board. Once in time, you manage to achieve some self sufficiency on mars, and are capable of producing propellant on Mars (or even better yet, Phobos), you could create a version that is specifically designed for transfer duty, transporting people to and from Mars, meaning you could have a variant that does no longer require heat-tiles or control-surfaces, that will dock with a Mars bound (and refueled) starship, that will transfer crew both to and from Mars.

[@nekomakhea9440]

There's a better version of Project Orion called Medusa. It's a pulsed fission sail. Instead of a heavy pusher plate with heavy shock absorbers, you use a lightweight thin sail to catch the energy after it's diffused enough to not need shock absorbers, so that it's a gentle tug instead of a sledgehammer blow. Then you get better thrust to weight without all the mass needed to absorb the explosive shockwaves.

Sorry if it sounds knitpicky Jordan, but I think technically flight in space between Earth and Mars should be called interplanetary space flight and flight in space between Earth's solar system and another star or star system interstellar space flight. I believe the VASIMR electro-magneto plasma drive that uses Argon gas or some other ionizable gas is able to maintain thrust considerably longer than this pulsed plasma drive, which would allow for acceleration based artificial gravity for a large portion of the trip, even if only at a fraction of earth G. Doesn't ad Astra say VASIMR could get a craft to Mars in about 40 days if sufficient electric current (from a nuclear reactor) were available? Multiple options are good though.

[@kennethferland5579]

Their is no way that VASIMR could produce even a noticable acceleration inside a vessel even on thouse insane 40 day trip ideas, the acceleration would be in millimeters per second and the 'fraction' would have a denominator of 10,000 which is close enough to zero for all practical purposes of health.
