One test mission, called the Satellite Test of the Equivalence Principle (STEP), is being developed by Stanford University and an international team of collaborators. STEP would be able to detect a deviation in the equivalence principle as small as one part in a million trillion (10 18). Get this from a library!

The Mini-STEP idea was conceived from a desire by NASA to reduce the cost of the Satellite Test of the Equivalency Principle (STEP) experiment below that of the already downsized Quick STEP concept. The goal was for the total cost, including launch vehicle and reserves to be in the $50 m range. Introduction to Satellite Communication is designed to meet the needs of working professionals and students. The first edition was a response to a request by many friends and associates for a basic and clear book that provides newcomers with an accessible way to gain knowledge and become productive. The second edition.

Using pairs of concentric free-falling proof-masses, STEP will be able to test the Equivalence Principle (EP) to a sensitivity at least five orders of magnitude better than currently. The scientific objectives of the STEP mission are to test the Equivalence Principle to one part in 10 17 ; search for a new interaction between quantum-mechanical spin and ordinary matter with a sensitivity of the mass-spin coupling constant g p g s = 6×10 at a range of 1 mm; determine the constant of gravity G with a precision of one part in 10 6 and to test the validity of the inverse square law with the.

The Satellite Test of the Equivalence Principle (STEP) will probe the underlying foundation of. Einstein's theory, the (local) equivalence of gravitational and inertial mass, ofter called the weak.

In principle, SQUIDs can detect relative displacements of the test masses with a sensitivity of 10 −15 m in 1 s. In STEP the sensor is optimized for maximum acceleration sensitivity and can detect a relative acceleration of 10 −15 ms −2 in 1 by: The STEP (Satellite Test of the Equivalence Principle) mission concept is similar to MICROSCOPE, but it relies on a completely different technology, which is expected to push the accuracy of WEP.

The MICROSCOPE satellite mission has tested the equivalence principle with unprecedented precision, showing no deviations from the predictions of general relativity.

CNES/D. Ducros According to general relativity, all bodies should fall at the same rate in a gravitational field, independent of their composition. STEP will carry concentric test masses to Earth orbit to test a fundamental assumption underlying Einstein's theory of general relativity: that gravitational mass is equivalent to inertial mass.

This grant provided support for the STEP (Satellite Test of the Equivalence Principle) program between October and September STEP, previously supported by NASA under Grant NAG 'A Satellite Test of the Equivalence Principle,' was selected by the European Space Agency for a Phase A study as a candidate for ESA's next medium size mission (M2).

The Satellite Test of the Equivalence Principle (STEP) aims to determine any difference in the rate of fall of test masses in an Earth-orbiting satellite to one part in of the total gravitational acceleration — a factor improve­ ment over existing measurements.

It is being developed by the European Space. During Phase A, the STEP Study Team identified three types of experiments that can be accommodated on the STEP satellite within the mission constraints and whose performance is orders of magnitude better than any present or planned future experiment of the same kind on the ground.

The scientific objectives of the STEP mission are to: test the Equivalence Principle to one part in 10(exp The Satellite Test of the Equivalence Principle (STEP) is a proposed (as of [update]) space science experiment to test the equivalence principle of general relativity.

The experiment is thought to be sensitive enough to test Einstein's theory of gravity and other theories. The basic configuration is that of a drag-free satellite where an outer shell around an inner test mass is used to block solar wind.
