Nearly fifty years after its inception, the Gravity Probe B satellite mission delivers the first measurements of how a spinning gyroscope precesses in the gravitational warping of spacetime. 
Classical interpretations of relativistic precessions
Relativists have exposed various precessions and developed ingenious experiments to verify those phenomena with extreme precisions. The Gravity Probe B mission was designed to study the precessionsExpand
Spacetime, spin and Gravity Probe B
It is more important than ever to push experimental tests of gravitational theory to the limits of existing technology in both range and sensitivity. This brief review focuses on spin-based tests ofExpand
Constraints on Kaluza–Klein gravity from Gravity Probe B
Using measurements of geodetic precession from Gravity Probe B, we constrain possible departures from Einstein’s General Relativity for a spinning test body in Kaluza–Klein gravity with oneExpand
Particle Acceleration by Shock Waves
Sir Charles Darwin (Nature 164, 1112–1114 (1949)) presumably thought that shock waves are responsible for accelerating cosmic rays. Nowadays shocks are widely recognized as a key to understandingExpand
Macroscopic Description of Astrophysical Plasma
In this chapter we treat individual kinds of particles as continuous media, mutually penetrating charged gases which interact between themselves and with an electromagnetic field. This approach givesExpand
The Generalized Ohm’s Law in Plasma
The multi-fluid models of the astrophysical plasma in magnetic field allow us to derive the generalized Ohm’s law and to consider different physical approximations, including the collisional,Expand
Adiabatic Invariants in Astrophysical Plasma
Adiabatic invariants are useful to understand many interesting properties of collisionless plasma in cosmic magnetic fields: trapping and acceleration of charged particles in collapsing magneticExpand
Monte Carlo simulations of the LARES space experiment to test General Relativity and fundamental physics
The LARES (LAser RElativity Satellite) satellite was successfully launched in February 2012. The LARES space experiment is based on the orbital determinations of the laser ranged satellites LARES,Expand

TLDR
Tests of general relativity at the post-Newtonian level have reached high precision, including the light deflection, the Shapiro time delay, the perihelion advance of Mercury, the Nordtvedt effect in lunar motion, and frame-dragging. Expand
Discontinuous Flows in a MHD Medium
The phenomena related to shock waves and other discontinuous flows in astrophysical plasma are so numerous that the study of MHD discontinuities on their own is of independent great interest forExpand

Gravity Probe B: final results of a space experiment to test general relativity.
TLDR
Gravity Probe B, launched 20 April 2004, is a space experiment testing two fundamental predictions of Einstein's theory of general relativity, the geodetic and frame-dragging effects, by means of cryogenic gyroscopes in Earth orbit, results in a geodetically drift rate of -6601.8±18.3  mas/yr.

Test of general relativity and measurement of the lense-thirring effect with two earth satellites
The Lense-Thirring effect, a tiny perturbation of the orbit of a particle caused by the spin of the attracting body, was accurately measured with the use of the data of two laser-ranged satellites,Expand
Test of Lense - Thirring orbital shift due to spin
The Lense - Thirring effect is a very small shift of the orbit of a test particle due to the spin of a body. It may be described as an orbital drag due to the gravitomagnetic field generated by theExpand
