The Pioneer anomaly or Pioneer effect is the observed deviation from predicted accelerations of the Pioneer 10 and Pioneer 11 spacecraft after they passed about on their trajectories out of the Solar System....
, affecting Pioneer 10
Pioneer 10
Pioneer 10 is a 258-kilogram robotic space probe that completed the first interplanetary mission to Jupiter, and became the first spacecraft to achieve escape velocity from the Solar System. The project was managed by the NASA Ames Research Center and the contract for the construction of the...

Pioneer 11
Pioneer 11 is a 259-kilogram robotic space probe launched by NASA on April 6, 1973 to study the asteroid belt, the environment around Jupiter and Saturn, solar wind, cosmic rays, and eventually the far reaches of the solar system and heliosphere...
spacecraft, and for his attempt to recover early data of the Pioneer spacecraft to shed light on such a phenomenon. He is interested in:
- Science motivation, mission design, and data analysis of high precision gravitational experiments in space
- Relativistic cosmology and alternative theories of gravity; theory of gravity-wave astronomy, including wave generation, propagation and detection
- Theory of and modeling for high precision astronomical reference frames; lunar and interplanetary laser ranging; pulsar timing experiments
- Optimization and control algorithms for long-baseline optical interferometry; analytical and numerical techniques for the white-light fringe parameter estimation.

of the LATOR mission aimed to testing Parameterized post-Newtonian formalism
Parameterized post-Newtonian formalism
Post-Newtonian formalism is a calculational tool that expresses Einstein's equations of gravity in terms of the lowest-order deviations from Newton's theory. This allows approximations to Einstein's equations to be made in the case of weak fields...

and the Flyby anomaly
Flyby anomaly
The flyby anomaly is an unexpected energy increase during Earth-flybys of spacecraft. This anomaly has been observed as shifts in the S-Band and X-Band Doppler and ranging telemetry. Taken together it causes a significant unaccounted velocity increase of over 13 mm/s during...
