Mating Hera: two into one
Video: 00:03:31
Hera is complete. ESA’s asteroid mission for planetary defence was built and prepared in two halves, but now, through a painstaking operation, they have been mated together to make a single spacecraft, ready for full-scale testing of its readiness for space.
The mating took place at OHB Bremen in Germany, with Hera’s Core Module raised more than 3 m above its Propulsion Module then gradually and carefully slotted into place, over a three-hour period. The modules had been placed in cages to ensure their correct alignment relative to each other down to a few tenths of a millimetre.
Hera’s Propulsion Module incorporates its propellant tanks – housed within a central titanium cylinder, the ‘backbone’ of the spacecraft – along with piping and thrusters, which will have the job of hauling the mission across deep space for more than two years, then to manoeuvre around the Dimorphos and Didymos asteroids.
Meanwhile Hera’s Core Module can be thought of as the brains of the mission, hosting its onboard computer, mission systems and instruments.
Once the tip of the Propulsion Module cylinder met the top deck of the Core Module the mating was complete. Then an initial test bolt was inserted to check the alignment was entirely correct in advance of the two modules being fully bolted together.
The combined Hera spacecraft is scheduled to go through a test campaign to assess its readiness for spaceflight, along with the two CubeSats it will carry aboard, in preparation for its October 2024 lift-off.

Digital modelling to build space missions faster
The ‘fit check’ is that moment in a mission’s lifetime when a satellite is first attached to the launcher adapter that will cradle it on its flight to orbit. This is supposed to be a mere formality, but uncertainty is present in its very name: what if these two items, typically manufactured in different parts of Europe, don’t fit together as planned?

This presentation is for folks who do not understand how their body has already been made commercially available to the cloud since 2005. IEEE is the International standards for Electronics and #Electrical #Engineering. You will find your body on the #web and commercially accessible via the same #wireless working groups for all wireless #devices. #How did it happen? How can you gain access to the biosensors that are magnetically routing the data instead of your lunch in your red blood cells? (folks, this one is for you and while it is not my a game, i give myself a b and if you want me to include anything please let me know. I am currently working on signs for the literal math from a to b so people can understand #energy harvesting.

Orbiting astronaut oversees robot team on Earth
Astronaut Frank Rubio aboard the International Space Station collaborated with a small team of robots on Earth to accomplish a complex task – a first test of a new approach to combine human and robotic capabilities for our return to the Moon and beyond.
