NASA HIAD vs Mars Info Lite
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NASA HIAD
Engage in a challenging space mission simulation where you must guide an inflatable spacecraft through atmospheric re-entry. Make critical decisions about shape, materials, and trajectory to successfully land cargo on Earth.
- Spacecraft re-entry simulation
- Inflatable aerodynamic decelerator mechanics
- Trajectory and speed control
- Vehicle customization
- Four levels of engineering challenges
- Star-based scoring system

A giant cone of inner tubes stacked together may someday help cargo, or even people, land on another planet or return to Earth. NASA calls the spacecraft technology HIAD - Hypersonic Inflatable Aerodynamic Decelerator. Learn the challenges NASA faces as it works to develop an inflatable spacecraft. Choose the right shape, materials and trajectory to use a HIAD to bring cargo back from space. To successfully guide an inflatable spacecraft through the super heat of atmospheric re-entry requires the right stuff. If you inflate too early, your shape is incorrect or your material isn’t strong enough - you burn up. And if you get all that right and miss the target the mission is a bust. Try your hand at landing a HIAD and become a rocket scientist. Advance through all stages at each of the four levels, collecting up to three stars for each successful landing. The HIAD game challenges players to successfully land a HIAD after launching from the International Space Station and arriving at a target ground point on Earth. To successfully reach the target, players must: •Undock from the ISS and use thruster control to steer the spacecraft towards the desired de-orbit point •Inflate the HIAD aeroshell to reduce velocity and protect the payload from the heat of atmospheric re-entry •Steer the inflated HIAD to the ground target prior to parachute deployment, taking into account the prevailing winds •Customize the HIAD vehicle to achieve different performance characteristics to improve results FEATURES •Multiple spacecraft configurations and options •Speed and trajectory controls •In-game introduction •Four levels of engineering mastery •Locked levels •Scoring for each level •Help section •Links to related website

Verdict
NASA HIAD and Mars Info Lite both sit at 4.4 stars, but that hides the real split: 96% of Mars Info Lite's written reviews are positive against 38% of NASA HIAD's. Mars Info Lite also leads on ratings volume (200 vs 8). NASA HIAD's advantage is iOS requirement (5.1.1 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.4 for NASA HIAD against 4.4 for Mars Info Lite. That said, the two scores are not equally well evidenced: Mars Info Lite has 200 ratings behind it against 8, so its average is the more settled of the two. Written reviews are what separate them: 38% of NASA HIAD's written reviews are positive against 96% of Mars Info Lite's.
NASA HIAD ships an update every 4 months, Mars Info Lite every 3 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
