ESA’s Hera mission lifted off on a SpaceX Falcon 9 from Cape Canaveral Space Force Station in Florida, USA, on 7 October at 10:52 local time (16:52 CEST, 14:52 UTC).
Hera is ESA’s first planetary defence mission. It will fly to a unique target among the 1.3 million asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering unknowns associated with its deflection.
Hera will carry out the first detailed survey of a ‘binary’ – or double-body – asteroid, 65803 Didymos, which is orbited by a smaller body, Dimorphos. Hera’s main focus will be Dimorphos, whose orbit around the main body was previously altered by NASA’s kinetic-impacting DART spacecraft.
By sharpening scientific understanding of this ‘kinetic impact’ technique of asteroid deflection, Hera should turn the experiment into a well-understood and repeatable technique for protecting Earth from an asteroid on a collision course.

![Hubble Spots Black Hole Beam Causing Stellar Eruptions
In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory.
The stars, called novae, are not caught inside the jet, but in a dangerous area near it.
A nova erupts in a double-star system where an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. When the white dwarf has collected a big enough layer of hydrogen, it explodes out into space.

![NOAA Debuts First Imagery from GOES-19
On Sept. 18, 2024, NOAA shared the first images of the Western Hemisphere from its GOES-19 satellite. The satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth.
GOES-19, NOAA’s newest geostationary satellite, launched on June 25, 2024, onboard a Falcon Heavy rocket from NASA’s Kennedy Space Center. Previously known as GOES-U, the satellite was renamed GOES-19 upon reaching geostationary orbit on July 7, 2024.
The ABI, GOES-19’s primary instrument, views Earth with sixteen different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth’s atmosphere, land, and ocean.
