While an aerocapture could slow an asteroid down enough to keep it from escaping back out into deep space, the problem you would face without a third body or additional applied force is that the periapsis (lowest point of orbit) now lies within the atmosphere. Subsequent orbital rotations would continue to slow it down until it falls into the atmosphere for good.
Aerocapture maneuver is very sensitive to uncertainties; thus in order to ensure a successful aerocapture maneuver, vehicle control authority is required. What is Aerocapture: is first of all a very rapid process, requiring a heavy heat shield resulting in high g-forces, Descent into a relatively dense atmosphere is suffciently rapid that the deceleration causes severe heating requiring What is Aerobraking: is a very gradual process that has the Aerocapture is a subcategory of aerobraking. Atmospheric drag is used to reduce velocity to a point the vehicle can enter a stable orbit with a minimum or no propellant burn. Aerocapture can be the prelude to descent and entry into the atmosphere. Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit by flying the vehicle through the atmosphere at the low point of the orbit.
'Aerocapture' transfers a vehicle into a closed stable orbit from a hyperbolic flyby trajectory. This technique eliminates all the energy in one pass. PDF | On Aug 4, 2020, Ye Lu published Aerocapture, Aerobraking, and Entry for Robotic and Human Mars Missions | Find, read and cite all the research you need on ResearchGate 2006-09-06 · Aerobraking and aerocapture In a recent post on Selenian Boondocks , Jon Goff comments on the essential development of aerobraking if we are to build a spacefairing society. His analysis is excellent, and I wanted to build upon what he said, in terms of how it applies to Mars exploration and why NASA should attempt it. A combined strategy of aerocapture and aerobraking is presented to achieve a near-circular orbit, starting from ah yperbolic trajectory, without requiring an orbital insertion burn. The paper examines the utilization of aerodynamic forces to capture a vehicle into a closed orbit and/or to modify an orbit.
From above, question 2, and partially 3, also apply here Aerobraking and aerocapture have been shown to be mission enabling for deep space orbiters and manned missions, and yield dramatic cost and mass The aerocapture maneuver is a technology that allows orbital capture with only one spect to aerobraking and by a factor of 1.63 with respect to a 370 s specific It has been proposed for use during aerocapture and aerobraking. Retrieved from Wikipedia CC BY-SA 3.0 A form of aerobraking in which no initial orbit-injection burn is performed. the atmosphere without an initial insertion burn, and emerges from this single pass in May 13, 2016 MSNW's magnetoshell aerocapture concept could help ease Interaction between the atmosphere and the plasma would slow down the In more recent missions, such as Mars Global Surveyor (MGS) [8] and Mars Reconnaissance Orbiter.

Aerocapture. Aerobraking is the action of atmospheric drag in This thesis presents the results of a conceptual design and aerocapture Two of the main classes of aero-assisted maneuvers include aerobraking and Feb 13, 2021 The related techniques of aerocapture, aerobraking, and atmospheric entry also attempt to use the body's atmosphere to help reduce propulsion Nov 24, 2020 Mars Sample Return in the early 2000's had a CNES-led aerocaptured orbiter.
Aerobraking and aerocapture (see below) are useful methods for reducing the propulsive requirements of a mission and thus the mass of propellant and tanks. Aerobraking is using atmospheric drag to slow down. Aerocapture is using the right amount of aerobraking to slow down enough to get captured into orbit from interplanetary speeds, but not slow enough that you can't stay in orbit and must land.

Here are a few of the main challenges of aerobraking and aerocapture: Aerocapture is best achieved with a biconic aeroshell design, with the aeroshell supported by Al honeycomb panels and allowing primitive aerodynamic maneuverability.

A form of aerobraking in which no initial orbit-injection burn is performed. Instead, the spacecraft plunges deeply into In Magellan's case, the aerobraking surfaces were just the body of the spacecraft and its solar arrays.
