To identify the most promising options for Mars entry, descent, and landing, and to plan development of the needed technologies, NASA's Human Architecture Team (HAT) has refined candidate methods for emplacing needed elements of the human Mars exploration architecture (such as ascent vehicles and...

The actuated aero-brake has the ability to control the trajectory and eventually reaching a predetermined landing position by changing its shape, and consequently its wetted surface, during the descent flight [9,23,24]. Reference [25] presented a de-orbit and guidance scheme to control the traje...

The €150-million (US$169-million) prototype IXV has a design somewhere between that of NASA's now-decommissioned space shuttle, which landed like a plane, and of the descent capsules used by the Russian Soyuz spacecraft and by the US commercial aerospace company SpaceX. Although the European...
