Vall Science Run
Pushing Kerbal science to the icy, airless edge of Jool's gravitational embrace.
The Vall Science Run is a campaign within the Kerbal Space Program's expansion into the outer system, focusing on the exploration of Vall, the second-largest moon of Jool. While not a single dated event in official records, this designation is widely recognized among KSC historians and career pilots as the era when long-range surface science became feasible beyond Kerbin. It marked the transition from simple flybys to sustained surface operations in deep space.

Lore & Background
The success of these missions proved that Kerbal technology could withstand the long transit times and radiation exposure inherent in reaching the outer planets. Unlike the Mun or Minmus, Vall required precise landing techniques on its airless, icy surface, with no atmosphere for aerobraking or parachute deployment. These achievements laid the groundwork for eventual colonization efforts at Laythe.
In Their Own Story
The surface of Vall was silent save for the hum of telemetry instruments. Commander looked up; the giant, swirling bands of Jool dominated the sky, a marble of blue and white hanging impossibly large against the void. The lander's legs crunched into the icy regolith. Back on Kerbin, they wanted numbers: atmospheric density, surface temperature, radiation levels. Here, amidst the cold shadows of Tylo's influence, it felt less like data collection and more like standing on the edge of the known universe.
Reader's Guide
A Vall Science Run begins with a precise Hohmann transfer from Kerbin to Jool, requiring careful timing for fuel efficiency. Pilots must first achieve orbit around Jool before inserting into a stable Vall trajectory, often using aerobraking within Jool's upper atmosphere if delta-V is limited. Once in Vall orbit, the primary objective is descent. The thin atmosphere allows for parachute deployment but requires retro-rockets for final touchdown to avoid impact damage. Upon landing, experiments such as the Barometer and Thermometer yield high-value science due to the unique environmental conditions. The return trip demands significant delta-V reserves. Successful completion of a Vall Run grants substantial career funds and unlocks advanced contracts involving Jool's other moons.
Did You Know?
- Vall is the second-largest moon of Jool.
- Vall has no atmosphere, so parachutes and aerobraking are useless; landing requires retro-rockets or careful powered descent.
- Retro-rockets are required for final touchdown on Vall to avoid impact damage.
- The Barometer and Thermometer yield high-value science on Vall due to unique environmental conditions.
- A Vall Science Run requires a precise Hohmann transfer from Kerbin to Jool.
Frequently Asked Questions
What defines the Vall Science Run?
It is a recognized campaign era focusing on exploring Jool's third-largest moon, Vall. This period marks the shift from simple flybys to sustained surface operations in deep space.
Why do KSC historians consider this event significant?
It demonstrated that long-range atmospheric science was feasible far beyond Kerbin's orbit. The success of these runs paved the way for future outer system exploration efforts.
What challenges do pilots face during this mission?
Pilots must navigate Jool's strong gravitational embrace while managing operations on an icy, atmospheric body. This combination requires advanced piloting skills and robust spacecraft design.
Is the Vall Science Run recorded in official government logs?
No, it is not a single dated event in official records but rather a designation used by historians and career pilots. It represents a collective era of achievement within the community.
What specific data was targeted during this campaign?
The primary focus was on atmospheric data collected at the edge of Jool's system. These experiments pushed Kerbal science capabilities to new icy frontiers.
