Luna is an orphaned girl with dreams to attend a prestigious academy. After her celebrated acceptance, the class embarks on a field trip to see a world being colonized first-hand. However, in the middle of the journey, a storm overtakes the space vessel, causing a pod with Luna and a small group of students to be jettisoned into a gravity well -- stranding them on a planet far from home. Now, with monsters at every turn and supplies running short, the group of strangers must do the only thing they can -- survive.

As a young woman, the spirited Asumi has only one desire: to someday travel to the stars in a rocket, with her father and ghostly friend Lion-san along for the ride.

Both of these anime deal with space and survival though in different ways. However, they both center around a small group of students and their relationships. They both have a family friendly feel to them and if you love one you will love the other as well.
It is the year 2356 AD, 189 years after a shockwave from a distant supernova decimated the Earth. Since that fateful day, humanity has begun training for a final mission to protect the planet from the inevitable oncoming 2nd shockwave - a mission whose failure means the annihilation of mankind. For Katase and her friends, their training at the foundation Stellvia is just the beginning of an adventure that could lead to saving the world, or seeing its end...
Both series heavily feature teens and children living in a furturistic society. There is a heavy emphasis on teamwork and friendship in both. While Stellvia is geared towards a slightly older audience, the themes and characters are quite similar, and provide a very similar feel throughout the series.
What happens when authority and consequence are removed? When the inmates truly run the asylum. On the spaceship Ryvius there are those who would fight for order, and many more who would fight to destroy it. Love, hate, anger, greed, avarice, and perhaps hope are the fuel for the Ryvius, and only one can save those who call it home...
Both UPS (Uninhabited Planet Survive for short) and Infinite Ryvius deal with youths being forced into a situation where they are in charge of everything including their lives, and the only way they can survive is to rely on each other. While UPS is much more "light" than Ryvius I think if you liked one you have a good chance of liking the other.
Two days a year, the members of a typical high school's marine club are allowed to take the boat out during summer vacation. Their destination is the fun filled Bonarl Island -- until a mysterious storm-related disturbance throws them into another dimension full of dinosaurs and oppressive soldiers! Now, with no way to get home, the students must rely on themselves, the voice saurus Zauls and the help of unlikely strangers as they struggle to survive amidst certain death...
Uninhabited Planet Survive and Jurassic Tripper both have a similar story: a group of students gets stranded on an unfamiliar world because of a storm and have to make it on their own until they find a way to get back home.
All is not as it seems on the part civilian, part military Aries space station. While visiting tourists or a fresh batch of cadets are just business as usual, a terrorist group planning an attack and a mysterious woman constantly getting "lost" in forbidden areas of the station is not. Soon enough, the regular life on the station comes to a sudden stop as different factions face off in its narrow hallways. And as the battle rages, the masks people wear are torn down. Unexpected alliances and bitter betrayals, love and sacrifice; nothing brings out people's true nature like war.
Survival, military or academic training...
Both main characters are stuck in a nasty scenario and they have to find a way to resolve it, by means of survival. The difference between the two series is that in one series the main characters are on familiar ground while in the other series they are lost in unfamiliar and unsafe ground. Another difference is the animation style.
I would seriously recommend one if you liked the other.
Both series are set in the future, and in space. Also, in both series, the characters barely know each other, and so will have to learn to bond if they're going to survive.
Both series are about a fight for survival.
