There are three options for orbital insertion at Mars: fully-propulsive, aerobraking, and aerocapture. The simplest method is propulsive orbit insertion; however,

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)

Start This article has been rated as Start-Class on the project's quality scale. Low This article has been rated as Low-importance on the Aerocapture technologies have the potential to enable orbital missions to the outer planets and their satellites by the judicious use of aerodynamic forces in a planetary atmosphere. These forces can be used to guide a spacecraft from an inbound approach trajectory to its final desired orbit. (Aerocapture, a close cousin of aerobraking, is an as-yet-untested technique that would use the friction of a planetary atmosphere to actually capture a spacecraft into orbit.

Aerobraking vs aerocapture

Aerocapture is best achieved with a biconic aeroshell design, with the aeroshell supported by Al honeycomb panels and allowing primitive aerodynamic maneuverability. The aeroshell would be covered with thermal protection materials capable of elevated temperatures of magnitudes that are a function of the expected atmospheric density, the surface area, the entry speed, spacecraft mass and Using aerobraking to rid yourself of 'all your velocity' (interplanetery velocity, relative to the orbital motion of the target planet) is called aerocapture.This has never been attempted before, and would require prescise atmospheric targetting (to within a few kms), precise details of the atmospheric density parameters, and perfect understanding of the spacecraft's atmospheric behaviour, all 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 300 x 300 km Venus Orbiter (OML Design Only) Ø2.65 m Reference: “Systems Analysis for a Venus Aerocapture Mission”, NASA TM 2006-214291, April 2006 Mass savings will scale up for Aerobraking is similar to these topics: Orbital maneuver, Orbital spaceflight, Aerocapture and more. Abstract. The paper examines the utilization of aerodynamic forces to capture a vehicle into a closed orbit and/or to modify an orbit. Attention is given to two techniques: aerobraking which uses drag during successive passes through the upper atmosphere to circularize a highly elliptical orbit, and aerocapture which transfers a vehicle into a closed stable orbit from a hyperbolic flyby Aerocapture definition is - the technique of using atmospheric friction to decelerate a space vehicle as it enters a planet's atmosphere : the use of aerobraking to slow down and capture a space vehicle.

Aerocapture is an orbital transfer maneuver used to reduce the velocity of a spacecraft from a hyperbolic trajectory to an elliptical orbit around the targeted celestial body. New!!: Aerobraking and Aerocapture · See more » Aerogravity assist Aerocapture technology is being considered for a broad range of future mission objectives. Although the orbit capture maneuver has never been flight tested, ablative and non-ablative entry capsules have been used throughout the U.S. space program, providing plenty of relevant experience.

3.3 Aerobraking Aerobraking is simulated by performing consecutive atmospheric passes until the desired apoapsis altitude is reached. HyperPASS automatically implements raise periapsis maneuvers if the user entered heating limit is exceeded during aerobraking. Also, HyperPASS will perform orbit insertion and orbit circularization

Although the orbit capture maneuver has never been flight tested, ablative and non-ablative entry capsules have been used throughout the U.S. space program, providing plenty of relevant experience. Aerobraking is then used to circularize the orbit. If the atmosphere is thick enough, a single pass through it can be sufficient to slow a spacecraft as needed.

Aeronautical and Astronautical Engineering United States Air Force Academy, 2001 Delivered mass fraction using aerocapture is compared with propulsive insertion with and without aerobraking. Aerocapture allows 90–250% increase in delivered mass to a 400 km circular orbit So for the mission’s 1,104,545 kg of fuel, 12,020 kg (1.09%) was used in the landing burn, 1,287 kg (0.12%) was used for de-orbit to aerocapture, 574,895 kg (52.05%) was used for the GTO injection burn, and 516,343 (46.75%) was delivered to GTO. To beat that performance, the dedicated tug has a problem because it probably can’t use aerobraking.

The paper examines the utilization of aerodynamic forces to capture a vehicle into a closed orbit and/or to modify an orbit. Attention is given to two techniques: aerobraking which uses drag during successive passes through the upper atmosphere to circularize a highly elliptical orbit, and aerocapture which transfers a vehicle into a closed stable orbit from a hyperbolic flyby trajectory. The main reason behind the selection of this research methodology is to give detailed knowledge about Trajectory of spacecraft in aerobraking. This research methodology also gives the knowledge about the various scholars and who had previously carried research on the topic (Dunham & Davis, 1999).

Aerocapture is a lot more challenging, since the deceleration has to take place a lot lower in the atmosphere in order to provide the required deceleration in such a short distance. 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.

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. Aerocapture is a lot more challenging, since the deceleration has to take place a lot lower in the atmosphere in order to provide the required deceleration in such a short distance.
