Fundamentals of Astrodynamics and Applications
We don't always want to burn near periapsis. Suppose we want to change the
height at periapsis. The most efficient place to change the radius of periapsis is at
apoapsis. Consider applying Af at some other point in the orbit. In this case, both
...
The main aerobraking phase began once the point of the spacecraft's periapsis
had been lowered to within 110 km above the Martian surface. As the
spacecraft's orbit was reduced and circularized during 330 drag passes in 75
days, the ...

Orbital Mechanics for Engineering Students
FIGURE 6.5 Figure 6.4, in which point A is the periapsis of the initial ellipse. In
Figure 6.5(b) rA0 =rA 1⁄4 1, which means the starting ellipse is a circle. Finally, in
Figure 6.5(c) rA0=rA 1⁄4 1=3, which corresponds to an initial orbit of the same ...

Eshbach's Handbook of Engineering Fundamentals
Three Euler angles, the inclination /. the longitude of the ascending node £2, and
the argument of periapsis to, are used to specify the spatial orientation of the orbit
. Size and shape of the orbit are fixed by the semimajor axis a and either the ...

The MESSENGER Mission to Mercury
Since sub- spacecraft periapsis longitude on Mercury moves 360° in 59 days, it
will take at least this long to obtain measurements for a global gravity model;
hence, determining a series of locally tuned gravity models will be part of
navigation ...

Mitigation of Hazardous Comets and Asteroids
It is useful to use periapsis passage relative to the asteroid to delimit between
different classes of motion. At launch a particle starts from an initial radius ro > qo,
since in general the initial periapsis (go) lies beneath the body's surface.

On the Dynamical Propagation of Subvolumes and on the ...
The motion begins at periapsis, but when it reaches the Y-axis, i.e. apoapsis, it "
hops" 7r-radians to the corresponding point on the lower half plane and then
returns to periapsis. To compensate there is a corresponding 7r-radian hop in the
...
