1 m/s to save for later, what a gangsta sentence.

"I left 1 Delta V in the spider engine, we will need that for later" Leave it to Bradley to minmax an entire one DeltaV unit during challange

The most mind-blowing thing about this mission to me was when you were talking about 2019 being "2 years ago" and then I realised that 2019 was, in fact, *2 years ago*. Time moves too quickly, man.

Thanks to 1.11 allowing us to remove the Kerbal's parachutes we can return to the good old days of surviving a fall from orbit using nothing but an oscar fuel tank as crush space

Next we’ll see 50 grams to moho and back

that moment when your ship is so small you have to specify "not including the kerbal"

Now that we can change a Kerbal's mass, the final barrier will finally be broken.

It's always hilarious to watch the timer in minimal mass missions. Imagine the meeting at KSC "Hey who wants to spend 2 1/2 years floating around in a space suit because we're too cheap to make a decent rocket so that you can have a normal Minmus mission that should take less than 20 days?"

Better have made sure Bill had an empty stomach going up

"Standing on the flag doesn't provide any significant advantage" Says the guy who specifically left 1 m/s of DeltaV left so he could reenter safely.

The bar gets even lower! Exciting to see how these hyper-optimized missions evolve with time

From what I remember, kerbals can actually survive re-entry if done right, so technically you wouldn’t need the radiator

Last time I was this early the KSP had adequate funding.

Time for the bi-monthly Bradley Whistance upload.

Could probably improve the mission using flags in some way, since they can work to lithobrake really well and can also protect a kerbal from heating.

Person: “So, how much Delta V did you leave in the de-orbit stage?” Bradley: “A Delta V.” Person: 😮

The game: "Rescue Babushka Kerman from low kerbin orbit." Bradley: "Babushka Kerman needs to go to Minmus first, and then land on the VAB."

Bradley in 2022: "To Minmus and back with 0 tons"

9:42 that ship hasn't sailed, you launched it into the sun with a 2 ton rocket

Now things like this are just incredible to me, amazing work my guy!

The external command seat has an ejection force slider on it now, free delta v when you leave the seat! Would love to see you start yeeting Bill out of that thing

Theoretically you could build a mass driver cannon, that fires a Kerbal to Minmus.

Was waiting for some inventory shenanigans

I still remember when you did a video about it a couple of years ago before the 1.11 update which makes it even better

I really like your low mass missions and i hope it doesn't hurt to ask for more

Bill's story played a gigantic role in my quarantine. Thank you so much for your fantastic work and vids!

Two hours after brad posted his video, a Chinese broke his record with a 0.8 ton spacecraft....

When your craft is so light you need lithobreaking on a kerbal to land on minmus

Me: builds an unnecessarily complicated contraption to go to Minmus This guy:

Bill's face makes a good brake pad.

love you're videos man keep it up!

Next comes Stratzenblitz with

was there a reaction wheel in there, or were you just using the vectoring is the engine to orient yourself?

What an absolutely brilliant video mate, I'm flabbergasted. Stay safe.🚀

Isn't it possible to use the "ejection force" on the command chairs to get some extra dV?

Hi Brad, I have a suggestion for you which is more of a piloting challenge than a build challenge. My proposal is "single burn to Minmus". Starting on the surface of Kerbin, launch directly to an intercept of Minmus, so the rules are: (1) no lighting additional engines after leaving the surface of Kerbin, (2) no throttling down below 33%, (3) when you shutdown your engines after launch you must be on course to reach the sphere of influence of Minmus. Bonus points if you can pull this off from the Woomerang Launch Site.

Optimized so much that the flag becomes crucial to the return trip!

Nearly three years, bob must love space

HE DID IT

he’s back

wow so spacious so comfortable for our great astronaut 😈

"after a few more orbits of kerbin" T+ 1y 284d MET

When the kerbal is a separate stage

This is really incredible!!! Might be a stupid question - with an engineer, how do you have SAS control?

He ended up waiting two years.

Next milestone: going to minimus on Eva fuel alone

I am curious how small the boost form standing on the flag is, reminds me of raising the launch height using the launch clamps to get those few extra meters

I wonder if it's possible to change up the mission profile by having a kerbal remove parts from the vehicle mid-flight. I don't know enough about planning the kind of mission that relies heavily on the quirks of stock KSP to function for me to be able to make any reasonable estimates on how this may work, but it does seem to be an option that might be possible to consider now.

Would it be possible to bring up a second (or more) EVA fuel tanks, maybe in a container, or if possible not attached, just sitting in the fairing? Then go EVA-only from LKO all the way to Minmus and back,? This might end up making the craft heavier, though.

remember when a 2.1 ton SSTO was impressive.

I’m using a similar method to preform a 3 parts to the mun and minmus mission. I succeeded a few weeks ago, but I’ve been lazy with the editing of the video. I was wondering how long it would take for somebody to make use of it.

WHOA. Admirable optimization!!

He is a ksp god

Can you make a really advanced ssto/spaceplane tutorial that really goes in depth?

Now if chucking stuff out of inventory created Delta-v...

Yaaas You're back!!!

Finnaly another legendary video

So the previous mission was 2019... and Bill's trip to Minmus took 2 years... COINCIDENCE!? OR DID THEY EACH LAUNCH AT THE SAME TIME!?!?!?!?!?

fun fact: this mission weighs about as much as the f-35b lift fan

Next: 1 nanogram spacecraft to Eeloo

If you had a liquid fuel tank attached to the craft which was decoupled at launch, you could wait until the little jet engine is at maximum thrust before taking off without wasting fuel. Although that is a bit of a cheat, since you are technically adding a lot more weight to the craft. Also, have you tried launching from different launch sites? That may or may not bring an advantage.

Low mass missions are my favorite!

A little orthopedic correction by the minmus surface

the engiennering evolved. we have 2 stage EVA packs now

YES!

Good work

4:07 - I know that feeling (although in my case I was going for absolute minimum _cost_ to LKO, rather than absolute minimum _mass_ to Minmus and back).

These challenges are the most kerbal thing ever

Finallyyy!!!

You're a legend

When is the odessy by bill coming back?

Ayo this was my teacher when I was a freshman

a kraken powered ladder can land on eve and return with less mass.

maybe start the flight at a bit of an angle so that the mun assist will boost your angle even more and get you into the same orbital inclination as minmus without any delta v expenditure?

New challenge, 3 ounces to Eeloo and back

I'm wondering how light rotors are. I'm thinking of a solar-powered rotorcraft to get out of thick atmosphere, and ion thrust the rest of the way. The kerbal would have no inventory or perhaps a parachute; that would be part of the saving, so it might be best to count the kerbal and inventory as part of these things. I might try this but don't have the patience to do it well. I'd be happy if someone better than me did it.

Idea: have an air intake offset by like 75km so you can get to lko on air breathing engines 🤷‍♀️

Me: designing a super complex transfer stage to get to minmus. Bradley: Nah Also Bradley: we should be able to survive hitting the surface of Minmus at 180kph.

you can use a flag instead of the radiator to save weight

Your game looks beautiful! What mods are you using?

6:40 A *small* orhtopedic readjustment

does launch mass include things you leave on the ground? including say, a mass driver?

Where is the odyssey by bill?

Hey Bradley! It feels weird either saying or typing that because my name is also Bradley!

Thoughts on how the mission could be further optimized?

Finally!

I wonder what the smallest mass to the mun and back is in realism mod

LETS GO im happy now

Bradley, just asking, did you know that you cant take 2 propellant tanks on your Kerbonaft? You just need to hold one with your mous, so you will have more fuel.

What are your visual mods ?

IDK if it improves the launch mass but what about the idea of ditching the chair entirely and using a KAL or movements of the Kerbal to control the ascent profile?

Can we deorbit and land Bill like that time, using only EVA pack and parachute?

This craft weighs less than my dad's CX-7....

does minmus have a tiny atmosphere or is that just the graphics mod making it look like it

Using the topography of of minmus you might be able to shave a little delta V.

From what I remember, don't ordinary command pods refill a kerbal's EVA pack? I don't think I've seen you use an actual command pod in quite some time- if at all- but was the idea of ramming a kerbal repeatedly into a command pod to go from one orbit to another too imprecise/nauseating to do?

what mod makes the sun look so cool

Why not use the kerbal's parachute for landing?

what is the sunflare that you use?

mass driver
