- We learn that Han Duoduo was orphaned as a baby in a tsunami, but rescued by Han Zi'ang and treats her just like one of his own grandchildren.
- While escaping from the collapsing prison, Liu Qi stops to save Tim by prying open the bars of the cell, risking his own life.
- Tim later returns the favor by assisting Liu Qi in installing the Lighter Core in the Sulawesi Earth Engine, saving him from being crushed. It's also implied that he saved Liu Qi after the latter's helmet shattered during the shockwave of Jupiter's explosion. Indeed, for two people who just randomly met in a prison, they become quite the Action Duo by the end of the film.
- Makarov is just an all-round pleasant guy; he congratulates Liu Peiqiang on his retirement, hands him a bottle of vodka as a retirement gift, and insists on helping Peiqiang navigate the outside of the Navigation Platform International Space Station, despite being a bit of a coward.
- As shown in the image at the top of this page, upon hearing Han Duoduo's pleas, hundreds of rescue workers turn their trucks around to go back to the Sulawesi Earth Engine to provide assistance, deciding that it's better to fight for a chance at survival rather than accept their fate.
- Even better, their efforts do allow the reconfigured engine to be reactivated. And they're not alone, for the Earth Engines in Singapore and Jakarta also activate in a similar reconfigured state after the Sulawesi engine reactivates.
- When Liu Peiqiang decides to launch the Navigation Platform International Space Station into the Sulawesi Earth Engine's plasma beam, he makes sure to detach the hibernation modules from the station and initiate evacuation protocol, sparing the rest of the crew from the same fate.
- Wang Lei's final command to his team, and more or less a command to the rest of Earth.Wang Lei: Members of rescue unit CN171-11. Attention. This is an order. Live on.
- The overall message of accomplishing the impossible by coming together and acting as one for the greater good. Constantly, throughout the film, we are shown that the actions of the main characters notwithstanding, someone else would have done the same things they did. Need to drive a lighter core to one of the Earth Engines? Multiple teams were en route, any teams who were too late to save their engine gets rerouted to the next engine. Need to break out of cryosleep to stop MOSS? Liu Peiqiang isn't the only one to have this idea, you can see shots of other astronauts breaking out of their capsules and attempting to reach the control station. Figure out a plan to ignite Jupiter? The Israelis thought of it too, although they didn't pursue it because there still wasn't enough flammable gas to use. Got your Earth Engines working and overclocked? Several other teams were all making the attempt. When we all work together, it is not merely that we can accomplish great things; rather, their accomplishment becomes an inevitability.
- Based on the restart reports as the protagonists pass Manila, they aren't the only team crossing country borders: The Turin (Italy) report was from Norwegian rescue team NO013-01 on the scene, and the Singapore Engine 2 restart report was from an English-speaking member of Czech rescue team HR011-08.
- Three years after the encounter with Jupiter, Liu Qi, Han Duoduo, and Li Yiyi have become an inseparable trio. Indeed, many others like the former workers of CN171-11 and other rescue teams greet him with respect. It's also apparent that Liu Qi had been honored for his bravery, as he's shown with a badge on his thermal suit.
- In general, it's nice to see everyone in high spirits in the epilogue. After only about a third of the named cast surviving until the end and everyone going through absolute hell to get here, it's nice to see everyone settle down in peace. Zhou Qian seems to have taken up a job as security, apparently busting Tim who seems to be swiping a couple boxes of merchandise from a store. The surviving men of the rescue team can be seen enjoying themselves at a restaurant and waving to Liu Qi with smiles on their faces. Even brother Yi greets him happily; remember, the last time he interacted with Liu Qi, he was screaming death threats at him!
- At the end of the film, it's shown that Liu Qi is training to be an official transport driver, taking the place of his late grandfather.
