Project SpaceX SuperHeavy

[Jeremyxxx]

I have thought of a Starship concept resembling the Falcon Heavy (utilizing the Pre-2021 Super Heavy booster design as the two landable boosters while the Post-2021 Super Heavy would be captured by the Mechazilla arms as usual).

I bet SpaceX will never try this, as it will be so loud that the launch pad will destroy.

This is from the official Payload Planner's Guide for the Delta IV EELV:



So NASA SLS document specifies an unmodified 5-m DCSS. So both the burn time and propellant/empty masses needs to be updated to reflect the LH2 tank stretch.

This would yield a liftoff thrust of 180-190 MN assuming the core stage would be throttled to a similar profile that Falcon Heavy is.

Still nowhere near the beast that Sea Dragon was proposed to be (350 MN).

I don't think this will ever happen. SpaceX has learned the lessons of FH and would probably just build a larger rocket. The successor to Super Heavy, I bet, will rival Sea Dragon and would exclusively launch from an ocean platform.

The SpaceX Ultra Heavy, which i called that Falcon Heavy-like rocket, would be the weirdest spacecraft to fly on Orbiter.

It would be nice to be able to select a launch direction, northern or southern, for the launch autopilot, in addition to a target orbit inclination.

If you want to launch south, just enter a negative inclination.

This addon would be the ideal for launching my fictional Cassini successor mission, which consists of an Titan Orbiter and lander, an Enceladus Orbiter, an Dione lander, an Iapetus Orbiter and CubeSat and a Phoebe Lander.

Also, the Cassini Successor Multi-probe mission's mother orbiter that will orbit Saturn in this proposed addon of mine, is called Giovanni, named after the father of Jacques Cassini

Now THAT would be a site to behold!

It has been a month since I simulated the placement of the Starship's dedicated Orbital Launch Tower at Launch Complex 39-A at Cape Canaveral, and On December 3rd, Musk announced that the construction of Starship's dedicated LC-39A pad had officially begun.

Great work!

Man and I thought being able to write code that could have a Falcon 9 booster land on a barge in the middle of the ocean was impressive, I continue to be more amazed

More ideas for the Starship scenarios may include the Orbital Mega Tanker, Artificial Gravity Starship variant, Orbital Cargo Transporter and the Mega Drones.

Thanks for creating this wonderful addon! I completed the 10km hop as well as the mission where Starship lands in the water near Hawaii.

My next adventure is going to be a Mars mission, picking the right launch window and bumping up the propellant level to 100% after reaching LEO (of course, in real life that will take a number of refueling tanker trips), then heading towards the Red Planet.

@statisticsnerd - Glad you like it! Good luck getting to Mars

@Jeremyxxx - Mega Drones!!?! Crazy but fun!

I set up a base on Mars, set the landing pad as target and missed it by just a few kilometers. I was heading towards it, then the suicide burn started and I ended up in a Martian canyon. One thing that went very well was that by trial and error, I managed to execute an aerocapture. That was awesome, barely clearing the surface and reaching a moderately elliptical orbit.

After tinkering for many months, I finally managed to get the reentry autopilot functioning - albeit in a fairly clunky way.
Its a bit of a roller-coaster ride, going from 1g - 2.5g with a 3g bump when it transitions from Reentry mode to Skydive mode.
Use BaseApproachMFD or IMFD "BaseApproach" to target reentry interface at:
120km alt.
1.5deg reentry angle
45deg anterior angle

It can handle reentry from 200km-500km LEO, with 50T payload max.
It now switches to Skydive mode between 15km-20km alt. automatically.

If anyone wants to try it out, a "patch" .zip with new .dll's is attached to this post.
Also includes new Starship mesh with some small cosmetic changes.

The "Tanker" variant still does not include reentry autopilot.

I'm just doing some modelling work on "Mechazilla", so will put a proper update on OH later.

Cheers,
Brian

Wow! Auto reentry works great.
Will there be an auto deorbit burn feature like on Crew Dragon?
