Passage: Although originally proposed to the French space agency CNES, it was considered too complex and expensive for a single national programme. Its acceptance within the European Space Agency's scientific programme, in 1980, was the result of a lengthy process of study and lobbying. The underlying scientific motivation was to determine the physical properties of the stars through the measurement of their distances and space motions, and thus to place theoretical studies of stellar structure and evolution, and studies of galactic structure and kinematics, on a more secure empirical basis. Observationally, the objective was to provide the positions, parallaxes, and annual proper motions for some 100,000 stars with an unprecedented accuracy of 0.002 arcseconds, a target in practice eventually surpassed by a factor of two. The name of the space telescope, "Hipparcos" was an acronym for High Precision Parallax Collecting Satellite, and it also reflected the name of the ancient Greek astronomer Hipparchus, who is considered the founder of trigonometry and the discoverer of the precession of the equinoxes (due to the Earth wobbling on its axis).

What countries make up the agency that Hipparcos was accepted to after being considered too complex for CNES?

Passage: The policy change faced legal challenges. Following a challenge in the U.S. District Court for the District of Columbia, on October 30, 2017, Judge Colleen Kollar-Kotelly blocked enforcement of the ban, writing that as far as could be seen, "all of the reasons proffered by the president for excluding transgender individuals from the military in this case were not merely unsupported, but were actually contradicted by the studies, conclusions and judgment of the military itself". In March 2018, Trump announced a new policy on transgender service members, namely a ban on those with a diagnosis of gender dysphoria, which would effectively be a ban on most transgender service members. The new policy was challenged in the U.S. District Court for the Western District of Washington. On April 13, 2018 Judge Marsha J. Pechman blocked enforcement of the policy, ruling that the administration's updated policy essentially repeated the same issues as its predecessor order from 2017, and that transgender service members (and transgender individuals as a class) were a protected class entitled to strict scrutiny of adverse laws (or at worst, a quasi-suspect class), and ordered that matter continue to a full trial hearing on the legality of the proposed policy. On January 21, 2019, the Supreme Court — with Chief Justice John Roberts and Justices Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Clarence Thomas forming the majority for the 5-4 opinion — allowed Trump's policy to go into effect while challenges in lower courts are adjudicated. On March 12, 2019, acting Deputy Defense Secretary David Norquist signed a directive to allow Trump's policy to take effect in 30 days.
