The Target:

Geology Type:

Gravity:

Pressure:


Default values for above choice, Choose "Other" to change:

 Mass density:
 Target Cohesion (lab scale):
 Assumed Cohesion at this crater scale:
 Friction Angle:
 Porosity (%):  


To Change Values select "Other":

Gravity:

 

The Explosive:

Explosive Type:

Explosive Weight (Yield)
(or equiv TNT weight for Nuclear)
Shape
Depth of Burst

To Change Values select "Other":

Specific Energy:

     Density


Actual Diameter:
and the Energy is:

To Change Values select "Other":
+ means buried, scaled to tnt radius

DOB Value:

The Impactor:

Impactor Material:
Impactor Diameter
(or choose crater diameter below):
Velocity:
From Vertical:

To Change Values select "Other":

Impactor Density

So the Mass is:
and the Energy is:
 
The Excavation Crater Size is:

Show me the Profile:
Crater Diameter
(for impacts, can input this and solve for impactor):
Depth
Excavation Volume
Rim Diameter
Lip Height
Formation Time
Melt Mass
Vapor Mass
PiV
Pi2
PiStrength
And it is in the Cratering Regime
Ejecta Characteristics:

Ejecta Mass
The mass ejected with velocity greater than
Is:  percent of total, or:
