The Pioneer 10/11 missions, launched in 1972 and 1973, and their navigation are reviewed. Beginning in about 1980 an unmodeled force of {approx} 8 x 10{sup -8} cm/s{sup 2} appeared in the tracking data, it later being verified. The cause remains unknown, although radiant heat remains a likely origin. A set of efforts to find the solution are underway: (a) analyzing in detail all available data, (b) using data from the New Horizons mission, and (c) considering an ESA dedicated mission. 
Resolving Pioneers' anomaly
The Pioneers 10 and 11, spacecrafts deployed to explore the outer solar system, are reported to have experienced a constant anomalous acceleration toward the Sun. I contend that a generally covariant
A Quick and Dirty Approach to Verify the Pioneer Anomaly
We present source code for the computer algebra system Mathematica that analyzes the motion of the Pioneer spacecraft using the public available ephemeris data from JPL's website. Within 15 minutes,
Does the Neptunian system of satellites challenge a gravitational origin for the Pioneer anomaly
If the Pioneer anomaly (PA) was a genuine dynamical effect of gravitational origin, it should also affect the orbital motions of the Solar system's bodies moving in the space regions in which the PA
The Pioneer Satellites Anomaly is a Natural Constant
It is believed that the Pioneer satellites anomaly could be resolved by the orbit determination programs (ODP) if some particular elements of the satellite that were omitted or rejected as non
Spacecraft Navigation and Timing Using X‐ray Pulsars
Pulsars are unique celestial sources that produce distinctive, periodic signals. Since their discovery, they have been considered as potential navigation aids and timing beacons to form a reference
Deep Space Navigation Using Celestial X-ray Sources
Spacecraft traveling into deep space operate well beyond the useful range of the Global Positioning System (GPS) and yet still may have requirements for precise navigation information for trajectory
Deep Space Navigation Augmentation Using Variable Celestial X-Ray Sources
The accurate determination of navigation solutions for deep space exploration spacecraft is a crucial element of mission operation. These solutions are necessary to ensure successful arrival at the
Can the Pioneer Anomaly BE Induced by Velocity-Dependent Forces? Tests in the Outer Regions of the Solar System with Planetary Dynamics
We analyze the impact of some velocity-dependent forces recently proposed to explain the Pioneer anomaly on the orbital motions of the outer planets of the solar system from Jupiter to Pluto, and
Advances in the Measurement of the Lense-Thirring Effect with Planetary Motions in the Field of the Sun
By processing more than 400 000 planetary observations of various types with the dynamical models of the EPM2006 ephemerides, E.V. Pitjeva recently estimated a correction to the canonical
Constraints on f(RijklRijkl) gravity: evidence against the covariant resolution of the Pioneer anomaly
We consider corrections in the form of ΔL(RijklRijkl) to the Einstein–Hilbert Lagrangian. Then we compute the corrections to the Schwarzschild geometry due to the inclusion of this general term to
