Neural Lander Uses AI to Land Drones Smoothly
Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often...
Briefs: Materials
Landing is stressful on a rocket’s legs because they must handle the force from the impact with the landing pad. One way to combat this is to build legs out of materials that absorb some of the...
Briefs: Mechanical & Fluid Systems
Heat shields are essentially used as the brakes to stop spacecraft from burning up and crashing on entry and reentry into a planet's atmosphere. Current spacecraft heat shield methods include huge...

Real-Time, Fuel-Optimal, Powered Descent Guidance Using Interpolated Time-of-Flight and Propellant Mass
Soft landing using rockets requires a trajectory to be planned for the lander from rocket ignition — typically several kilometers in altitude and moving at up to 200 m/s — to the point near the surface with near-zero velocity. The exact...

Novel Vent Design Features Variable Flow Control and Rain Protection
NASA’s Marshall Space Flight Center scientists have designed a vent that can be useful for purging closed compartments, while preventing backflow and foreign object entry. The technology uses a system of configurable devices to provide variable flow control and prevent water,...
Briefs: Mechanical & Fluid Systems
Traditional heat shield design isolates the functions of the thermal protection system (TPS) from the underlying load-carrying structure. This is due to the use of brittle TPS material that...
Briefs: Aerospace
Some unmanned aircraft designs attempt to combine the vertical takeoff and landing (VTOL) and hover capabilities of a helicopter with the increased speed and range capabilities of fixed-wing airplanes. Stop-rotor...
Briefs: Aerospace
There are two commonly used options to transport large-volume and heavy cargo across the ocean: container ships and airline transport aircraft. Container ships take about 3 to 4 weeks to deliver...
Briefs: Aerospace
NASA's Langley Research Center has designed a Multifunctional Boost Protective Cover (MBPC) for a Launch Abort System (LAS). In the event of a crewed launch, the...
