No, Aerobraking and Aerocapture are two different Aeroassist techniques Belchja 21:30, 26 August 2006 (UTC)

In an aerocapture manuever, aerodynamic forces are used to decelerate a vehicle from its hyperbolic approach trajectory into a closed orbit about a planet in a single atmospheric pass. An aerocapture maneuver employs a single atmospheric pass to reduce orbital energy and establish a closed orbit. Modulating the spacecraft’s vertical lift component (via bank control) during atmospheric flight in an optimal fashion will minimize the post-exit propulsive burn required to establish a target orbit. 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.

This implies much higher forces and heat-fluxes, which require some sort of aeroshield/TPS system. Here are a few of the main challenges of aerobraking and aerocapture: No, found the book, and it's aerobraking. LouScheffer 11:13, 29 October 2009 (UTC) It is not clear whether a single pass through a planetary atemosphere to change trajectory without entering orbit as occurs in some SF stories is aerobraking or aerocapture. I would consider it aerobraking. Danwoodard 02:58, 6 September 2018 (UTC) Table 1: Aerocapture vs. Propulsive Capture [6] Figure 1: Orbits of the Mars Moons [ 7] The advantages of using a heat shield for aerobraking or aerocapture at Mars when using chemical propulsion are substantial. Aerocapture and aerobraking orbits at Mars are displayed in Figure 2.

The following What does aerocapture mean? A form of aerobraking in which no initial orbit-injection burn is performed. Instead, the spacecraft plunges deeply into Examples of how to use “aerocapture” in a sentence from the Cambridge Dictionary Labs Aerobraking vs Aerocapture.

This would eliminate the need for most of the large amount of fuel now needed for delivering a spacecraft into the desired orbit around Mars.) Into 300 x 300 km Venus orbit with same launch vehicle, Aerocapture delivers: • 1.8x more mass into orbit than aerobraking • 6.2x more mass into orbit than all chemical 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. The resulting drag slows the spacecraft.

A relatively low amount of energy is removed per pass. 'Aerocapture' transfers a vehicle into a closed stable orbit from a hyperbolic flyby trajectory. This technique eliminates all the energy in one pass.

Instead, the spacecraft plunges deeply into In Magellan's case, the aerobraking surfaces were just the body of the spacecraft and its solar arrays.

The resulting drag slows the spacecraft. Aerobraking is used when a spacecraft requires a low orbit after arriving at a body with an atmosphere, and it requires less fuel than does the direct use of a rocket engine.
