The flight computer on Python One counts mission time the simplest way there is: seconds since launch. That's perfect for calculations and useless at a glance. Is 100000 seconds one day or three?

Turn it into the clock the flight controllers read, one step at a time.

Split the mission time into whole hours, the minutes left over and the seconds left over, and print:

27 h 46 min 40 s

// divides and keeps only the whole part; % gives what's left over. An hour has 3600 seconds and a minute 60.

Print hours, minutes and seconds

Calculate from elapsed_s

Mission control shows time like a clock, two digits for every part. Change the print so it shows:

27:46:40

Every part gets two digits, so 3725 seconds would show as 01:02:05. In an f-string, {minutes:02d} pads a whole number with zeros to two digits.

Show it as a clock

Pad every part

Long missions count days as well. Mission control displays often write elapsed time as days, a slash, then the clock: DDD/HH:MM:SS. Add the days, with three digits:

001/03:46:40

A day has 86400 seconds. Once the days are taken out, the hours are only what's left of the last day.

Add the days

# ISS completes one orbit every 92 minutes
# How many full orbits in 24 hours?
minutes_in_day = 24 * 60
orbit_period = 92

full_orbits = minutes_in_day // orbit_period
remaining = minutes_in_day % orbit_period

print("Full ISS orbits per day:", full_orbits)
print("Minutes into next orbit:", remaining)

# Mars signal delay: 1,124 seconds
# Break into minutes and seconds
signal_delay = 1124
minutes = signal_delay // 60
seconds = signal_delay % 60
print(f"\nMars signal delay: {minutes} min {seconds} sec")

# Distribute 50 rations among 6 crew members
rations = 50
crew = 6
per_person = rations // crew
extras = rations % crew
print(f"\nRations per astronaut: {per_person}")
print(f"Extra rations: {extras}")

# Check if a mission number is even or odd
mission = 42
if mission % 2 == 0:
    print(f"\nMission {mission} is even")
else:
    print(f"\nMission {mission} is odd")
