I am having trouble even landing on the planet. My health is up to Level 12 and I have Mech Armor with Lasers at level 13 in Speed and Damage. Yet, I still get destroyed landing on the planet. I lowered the difficulty to "Pussy" level and still get trashed even before landing.

What the heck else do I need?

The Rubia planet briefing tells you that you need to be able to withstand “a large amount of impact damage” to land on Rubia.

This is not flavor text. I’m not being coy with some abstract “impact” mechanic. There is quite literally some amount of impact damage you will be taking when attempting to land on Rubia. And if your equipment does not have what it needs for you to survive said impact damage, then you will die. The difficulty level will change this threshold, but it will not make it go away.

The hint in the planet briefing says, if you can research “Planet Discovery Rubia”, then you already have all the technology you need, to craft everything you need. The converse is: Any technologies not required for Planet Discovery Rubia are not required to land.

Also, Rubia gives you a warning as you travel there if that journey will result in your death. This warning also crucially tells you how close you are to satisfying the requirement to land safely.

I hope this helps.

Thanks. I was able to land. But, yikes. This is one messed up planet.
