Hera is a spacecraft developed by the European Space Agency for its space safety program. Its primary mission objective is to study the Didymos binary asteroid system that was impacted four years earlier by the NASA Double Asteroid Redirection Test (DART) spacecraft and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid from a colliding trajectory with Earth.
The Hydrogen Epoch of Reionization Array (HERA) is a radio telescope dedicated to observing large scale structure during and prior to the epoch of reionization. HERA is a Square Kilometre Array (SKA) precursor instrument, intended to observe the early universe and to assist in the design of the full SKA.
Hera probe and its 2 CubeSats, Milani and Juventas. Hera is the European component of the ESA–NASA AIDA mission. The Hera spacecraft, approved on 29 November 2019, [24] will focus on key measurements to validate impact and asteroid deflection models, such as the detailed characterisation of the impact crater made by the DART impactor.

A staple of the ESA's Science Doctrine is the Cosmic Vision programme, a series of space science missions chosen by the ESA to launch through competitions, similar to NASA's Discovery and New Frontiers programmes. It succeeds the Horizon 2000 and Horizon 2000+ programmes which launched notable missions such as Huygens, Rosetta and Gaia.
Other detector systems were added as the focus on special physics processes was extended, for example, forward instrumentation for diffractive physics far down the HERA tunnel. While H1 was a general-purpose detector, its main design feature was an asymmetric construction to cope with the boosted center of mass in the laboratory frame due to ...
The HERA South Hall where the ZEUS experiment was located. ZEUS was a particle detector at the HERA (Hadron Elektron Ring Anlage) particle accelerator at the German national laboratory DESY in Hamburg. It began taking data in 1992 and was operated until HERA was decommissioned in June 2007.
Don Quijote is a past space mission concept that has been studied from 2005 until 2007 by the European Space Agency, and which would investigate the effects of crashing a spacecraft into an asteroid to test whether a spacecraft could successfully deflect an asteroid on a collision course with Earth.
HERA was used mainly to study the structure of protons and the properties of quarks, laying the foundation for much of the science done at the Large Hadron Collider (LHC) at the CERN particle physics laboratory today. HERA is the only lepton–proton collider in the world to date and was on the energy frontier in certain regions of the ...
