Mission Tools
Celestial calculators and calendar converters for navigating the galaxy.
Journey Parameters
Choose how to compute travel outcomes
0.05 = 5% light speed
Speed at destination
Acceleration capability. 70g = extreme
Maximum velocity the ship can achieve
Time for light to travel the distance
Use 0.10 for 10% light speed
Enter time length, then pick a unit
Initial speed before braking (e.g., 0.10 = 10% c)
Constant deceleration used until full stop
Travel Calculations
Configure journey parameters and calculate to view trajectory.
Ship accelerates from start speed to peak, then decelerates to end speed. Average speed = (start + end) / 2. Time = distance ÷ average speed.
Speed & Distance Quick Tool
Enter speed as a fraction of c (e.g., 0.10)
Edit either distance input; the other auto-converts
Enter speed and distance, then calculate to view km/s and travel time.
Earth → Syrtis
e.g., 2025-11-01T12:30:00
Syrtis → Earth
Earth Timestamp
Enter Earth ISO and convert to view Syrtis date.
Syrtis Timestamp
Enter Syrtis date and convert to view Earth timestamp.
19 months (Primus–Novendecimus) × 73 days = 1,387 days/year. Each month has 10 weeks of 7 days + 3 bonus days. Year 51 PA begins November 1, 2025.
Weapon & Target Settings
Target Parameters
Distance to target at start
Target velocity
0° = straight at you, 90° = perpendicular, 180° = straight away
Weapon Parameters
Initial weapon velocity
Sustained throughout flight
Intercept Results
Configure weapon and target parameters, then calculate to view intercept time.
Kinetic: Constant velocity intercept.
Missile/Drone: Uses quadratic kinematic equation. For angle scenarios, relative velocity components are resolved geometrically.
