Documenting my travel to every country/territory in the world following ISO 3166: 60% (150 of 249) on 1 planet/moon(s) done and counting…

Flight Day 4 I woke up early and watched the launch of Starlink Group 11-13 on YouTube. Shortly after, SpaceX contacted us and informed us that we would be flying over Mongolia during the second stage deorbit burn. We opened the cupola and tried to observe the event, but had no luck. Still, we all enjoyed the view as we flew from the Bay of Bengal all the way to the Arctic.

Hello, Antarctica. Unlike previously anticipated, from 460 km above, it is only pure white, no human activity is visible.

We’re gonna watch a rocket launch while on our way to a rocket launch. 🚀

2034 Earth–Venus–Mars opportunity looks promising. 10–15 on-orbit refueling operations may be needed to make a crewed ship full. Most can be done at an altitude of 180–200 km, made possible by Starship’s size. The final refueling may be performed at a higher altitude of ~2000 km, just below the Van Allen belt. Earth departure on 2034-08-21 from 2000 km orbit. A Trans-Venus Injection burn of ~3.7 km/s will place the ship on an Earth–Venus–Earth free-return trajectory. Venus flyby is expected on 2034-12-19, 120 days after departure. Two weeks before the encounter, if the mission proceeds as planned, a 25-m/s maneuver will shift the trajectory from Earth-return to Mars-bound. If not, the ship will free return to Earth in September 2035. The Venus gravity assist will send the ship into another Earth free-return trajectory, with Mars flyby around 2035-06-02. One week before reaching Mars, a system health check will determine whether to commit to Mars Orbit Insertion. If it’s GO, a small 10-m/s manuever will put the ship to less than 100 km altitude periapsis. Otherwise, a Mars flyby will lead to an Earth return in May 2036. The ship will enter the Martian atmosphere at about 9.4 km/s, performing an aerobrake to slow to 4.88 km/s and capture into a 100x140000 km, 7-day period high elliptical orbit. At apoapsis, a 50-m/s plane change will align the inclination with Mars’ equator, followed by additional aerobraking to remove about 650 m/s of velocity, placing the spacecraft in a 120x6128 km orbit. A 550-m/s burn at 6128 km altitude will then adjust the trajectory into Phobos orbit. The ship will stay at Phobos for about 7 days. The Mars–Phobos L1 point is only about two miles above Phobos’ surface, and Mars would dominate nearly half the sky, appearing about 80 times larger than the Moon from Earth. The ship will depart for Deimos afterward. Two burns totaling roughly 750 m/s will transfer the ship from Phobos to Deimos. And the ship will stay at Deimos for 7 days more. From Deimos, the ship will raise its apoapsis to form a 20000x140000 km altitude, 7-day orbit, requiring about 420 m/s of delta-v. At apogee, a 50-m/s burn will adjust inclination and lower periapsis to ~500 km for final Trans-Earth Injection. If time and propellant allow, the orbit can be aligned to a polar inclination for Mars ice-cap observations before departure. A Trans-Earth Injection burn at 500 km altitude, requiring 1.5–1.6 km/s of delta-v in early July 2035. If departure on the first days in July, Earth arrival is expected in December 2035. If missed that window, a March 2036 arrival may look more feasible. Nominal mission duration: 490 days, with 30 days in Mars orbit and 14 days at Phobos and Deimos. Two planets, two moons for 3.7+0.025+0.010+0.05+0.42+0.55+0.75+1.55=7.06 km/s Δv

My 36th flight of 2025 was fram2. My 36th flight of 2026 is an Ultimate Aviation helicopter (ZS-RDW) flight from Icetugs Argus to Bouvet Island. This is my 1146th flight of all time. Bouvet Island (ISO 3166-2:BV) has become the 150th (of 249) country/territory I have visited. 🇧🇻

Day 7 at sea: Today is our arrival day. We officially entered Norwegian territorial waters at 06:35 (UTC+1) and spotted Bouvet Island for the first time around 9 am. Our ship is currently holding position about one nautical mile northeast of Bouvet Island. According to the weather forecast, there may be a window of good weather just before sunset tomorrow. We will review with the helicopter pilot for the latest weather conditions and decide on the landing time tomorrow in the morning. Stay tuned.

Day 8 at sea: I woke up this morning at 09:40, just in time for the helicopter practice. In the afternoon, when the weather improved, we began flying supplies and personnel onshore. The first test flight took off at 17:02, and we continued with two more passengers and three more cargo round trips until 19:05. Unfortunately, I didn’t manage to get on the helicopter before sunset. We will continue transporting the remaining supplies and personnel to the island tomorrow. Hoping the weather will be good.

Heard Island and McDonald Islands (ISO 3166-2:HM) is one of the most difficult countries/territories on ISO 3166 for any human to legally set foot on. You would probably have to organize your own scientific mission in order to be granted access. Our crew member, Eric Eric Philips, was lucky enough to set foot here in 1996. Another is, remarkably, U.S. Minor Outlying Islands (ISO 3166-2:UM), as the U.S. Fish and Wildlife Service has not issue any permits in recent years, with a notable exception of President Obama’s visit to Midway Atoll in 2016. I also searched for Bouvetøya (ISO 3166-2:BV) while in orbit, unfortunately, it was covered by clouds.
