aerodynamic braking
Blocker door type thrust reverser.
Decelerating an aircraft by using means other than wheel brakes. The aerodynamic braking can be done by one or more of the following methods:
i. Keeping the nose of the aircraft high with the nose-wheel off the ground. This technique is normally used in combat aircraft. This is the most common usage.
ii. Using airbrakes or a drogue parachute. Airbrakes are used by airliners, whereas drogue chutes are used by combat aircraft.
iii. Using reverse thrust in jet engines or reverse pitch in the case of propeller aircraft.

Tender issuethe main objective of the activity is to investigate trade-off and design the gnc and fdir algorithms needed to extendthe autonomyof the aerobraking phase for envision and future planetary missions.
"The team worked diligently to prepare for aerobraking and we are enjoying the benefits of those countless hours now" said Nick Sealy, spacecraft aerobraking phase lead from Lockheed Martin Space in Littleton, Colorado.
Reaching a low Mars orbit needs additional impulsive 1.4 km/s or aerobraking. Thus, getting a spacecraft to a low Mars orbit with an E-sail would save 1.1 km/s of impulsive [DELTA]v and make aero-braking unnecessary.
Coverage encompasses orbital debris, dynamical systems theory, autonomous aerobraking, trajectory optimization, formation flying, conjunction assessment, non-earth orbiting missions, the Artemis mission, planetary mission studies, spacecraft guidance, satellite constellations, the Messenger at Mercury, large space structures and tethers, and rendezvous, among other topics.

He also added a slight forward stick pressure for aerobraking until 40 knots below approach speed, when he applied full aft stick.
"The principle of aerobraking is to increase the surface over mass ratio of an orbital object, to accelerate the fall-out by increasing the drag on the system," Santerre said.
Once the radar mission was complete, the spacecraft was moved into a lower orbit to map the Venusian gravity field and to test aerobraking techniques.
Surveyor pioneered the routine use of aerobraking, a practice that entails repeatedly dipping into the Martian atmosphere to reshape its orbit from a highly elliptical path into a nearly circular one.
MRO then began its aerobraking sequence to lower the spacecraft into its final orbit.

This maneuver is called "aerobraking" and gets MGS to its final polar orbit using almost no fuel.
