Dawnbreaker mk2
Classification: Lunar Flyby Launch Vehicle (LFLV)
Mission Profile: Apollo's Herald Lunar Flyby & Moon Proximity Science Mission

Technical Specifications:

Gross Liftoff Mass (GLOW): 186.3 tonnes

Total Delta-v: 12,994 m/s (Trans-Lunar Injection Delta-v: 3,361 m/s)

Payload Capacity: 4.7 tonnes (to Low Earth Orbit) / 342 kg (Lunar Probe Mass)

Orbital Lifespan: 3 days 16 hours (Active Operation) / 29 days (Hibernation Mode)

I'm trying to use RCS thrusters to stabilize an orbital stage, but I can't get them to fire no matter what I do.

Whether they're standard helium thrusters or using some other propellant, Kerbal engineer shows they have fuel and I have RCS delta V, but I can't use them in flight. I've made sure I have high pressure tanks for the RCS propellant as well. I've tried adding extra Helium to pressurize the system as well, still no luck.

If anybody knows what I'm doing wrong here, any help would be appreciated.

EDIT: RESOLVED. Turns out the interstage I was using for fairings didn't allow crossfeed. I fixed it by switching to a different interstage.

Does anyone know what causes this error and how to avoid it? It occurs relatively often when I do simulations starting in Earth's orbit.

some time recently this got updated, and now i can no longer make polar orbit probes to scan all biomes? how do i actually get this to work? what sorta orbit do i need?

On the 22nd of March, 1959, the Prometheus II, an upgraded Prometheus I featuring upgraded tanks and avionics, nearly quadrupling its payload capacity (~.5t to ~1.9t to LEO) and a test version of the SilverStage-L, based on previous sounding rocket stages and designed for TLI, launched for the first time. It carried a stripped down SilverStage-L, with a small cosmic ray satellite on top of it, known as Exsat VI. It successfully entered a ~215x75,000km orbit.

The second Prometheus II launch carried Exsat VII, a near identical satellite aside from slightly larger solar panels, into the same orbit on July 30th.

The third Prometheus II occurred on October 7th, 1959. It carried the full SilverStage-L TLI stage, with a small probe, dubbed Luun I on top. It entered a 160x160km intial orbit, around 30 minutes before performing TLI. On the 10th of October, it impacted the Moon, beating Luna II, although Luna I would have beat it to the first object in the Lunar sphere of influence.

Luun II and Luun III are both slated for 1960 launches, with Luun II being another Lunar impactor, and Luun III using a slightly better Prometheus IIb, with an upgraded TLI stage, to send a small SRM with it to enter Lunar orbit.

I've seen them acting weird througout my playthrough, but now i finaly reached orbit, they've just split into multiple lines. anyone know what could be causing this? It's my first time playing rp1 so i really have no clue what i'm doing.

Tried to tune all of them to 7540g. Managed a ±7g maximum variance with imperfect fuel consumption rates, so take the results with a grain of salt. Rendered in 9K for if anyone wants to zoom in on the text.

Edit: Round#2, Peaked#2, and especially Sharp#1 seemed to perform the best this round, while Waisted, Round#1, and especially Round#3 performed the worst, based on peak altitude and drag. Flat included for control only.

Any ideas? EDIT - i created a fresh install to attempt this, no other mods are there save for the ones required for Sol

EDIT 2: My specs: Ryzen 7 3700x, 32gb RAM, RTX 3070 nonfree/proprietary drivers, all running on an NVME SSD, Fedora Linux with kernel 7.0.3 (that part's probably not relevant)

Its hard to show in game cuz of clouds, but you can clearly see the effect when I start up the Game. It shows Earth for a split second in the menu while it loads and then goes back Kerbins surface, does anybody have an Idea for what could be causing this?

I've heard things like efficiency goes down over time on just that experiment that's already maxed out, but is there any ACTUAL reason not to squeeze a couple dozen science out of flight?

Image below is me force running 1 biome for 15 minutes.

Just started playing rp1 after watching some videos about it. I love the challenge of it. In the videos I've seen, during simulation launches there's usually more on the toolbar but I can't seem to figure out how to see the rest of it. The little arrows do nothing for me and Mechjeb is the only thing that pops up. Thanks for any help
