Hi Grandson, I am younger than you.

What it is? Who are “they”? (see below)

And yeah, “they” set it into orbit.

Answer:
This one of the most perfect sphere ever created. For proving Einstein’s theory of relativity.
Only a few got that right, but I have given points for Gyroscopes as well, because the question was not very clear.

    NASA/Stanford University Gravity Probe B (GPB) team announced that the geodetic effect predicted by general relativity has been confirmed to within 1%.
    At the heart of the GPB mission are spinning superconducting niobium spheres, engineered to be the `roundest objects’ ever made.

    not sure the exact expected ans. so kindly refer:

    Probably one of the most perfect spheres ever created. Part of “Gravity Probe B”s Novak Gyro used by NASA to prove 2 of Einstein’s theories.

    A gyroscope (the most perfect man-made sphere created) from Gravity Probe B, sent into space by NASA.

    From the BBC: Gravity Probe B uses four ultra-precise gyroscopes to measure two effects of Einstein’s general relativity: the geodesic effect and frame-dragging.

    Stanford University Technician Larry Novak holds the gyroscope rotor.

    Gravity Probe B (GP-B) is a satellite-based mission which launched on 20 April 2004 on a Delta II rocket. The spaceflight phase lasted until 2005;its aim was to measure spacetime curvature near Earth, and thereby the stress–energy tensor (which is related to the distribution and the motion of matter in space) in and near Earth. This provided a test of general relativity, gravitomagnetism and related models. The principal investigator was Francis Everitt.

    It is one of the Gyroscopes used in Gravity Probe B experiment funded by NASA n based on a Stanford team.
    NASA funding and sponsorship of the program ended on 30 September 2008, but GP-B has secured alternative funding from King Abdulaziz City of Science and Technology.

    It’s a spherical gyroscope used in Gravity Probe B; “A spinning spherical gyroscope in Earth orbit should wobble due to frame dragging.” “The gravity probe experiment is a joint mission of NASA and Stanford University’s Physics Department.”

    Gravity Probe B set into orbit by NASA to test Einstein’s theory of relativity. It uses 4 gyroscopes called “some of the most perfect spheres ever made” to measure the geodesic effect and frame dragging. Led by scientists from stanford, including Prof. Francis Everitt.

    Nasa Gravity Probe B..The first pic is the gyroscope rotor Coated with the super-conducting metal known as niobium,

    The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame-dragging, the amount a spinning object pulls space and time with it as it rotates.

    They are the four spherical gyroscopes set into motion to detect frame dragging and prove Einstein’s Space-Time Curvature. “They” is NASA

    That’s a precision gyroscope that was used by NASA to validate a few predictions of Einstein’s general relativity theory.

    // 0 points for me please, as I tin-eyed this one.

    One of the super-spherical gyroscopes of Gravity Probe B launched by “NASA” to verify general relativity.

    One of the gyroscopes for the Gravity Probe B experiment. NASA & Stanford sent it to space.

    Spherical gyroscope used in Gravity Probe B.

    The Gravity Probe B experiment comprises four London moment gyroscopes and a reference telescope sighted on HR8703 – IM Pegasi, a binary star in the constellation Pegasus. In polar orbit, with the gyro spin directions also pointing toward HR8703, the frame-dragging and geodetic effects came out at right angles, each gyroscope measuring both.
