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

The call

The clearest difference is rating: NASA HIAD at 4.4 against Spacecraft AR's 3.1. NASA HIAD also leads on iOS requirement (5.1.1 vs 15.0). Spacecraft AR's advantage is review sentiment (53% vs 38%) and ratings volume (25 vs 8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

NASA HIAD holds the better App Store score, 4.4 against 3.1. Both are backed by a comparable volume of ratings — 8 and 25 respectively. Written reviews complicate that: 38% of NASA HIAD's written reviews are positive against 53% of Spacecraft AR's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

NASA HIAD ships an update every 4 months, Spacecraft AR every 7 months. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
