R .. and how it will look on the moon (Credit: NASA) It has three degrees of freedom,
provided by waist, shoulder and elbow joints; and three links, - kingpost, arm and forearm, each of them 3.75 metres long. From the ground it can unload from the deck of a lander around 6m high; the first- generation design can lift 150kg on earth, 500kg on Mars, and 1000 kg on the moon. Maximum reach when configured as a horizontal boom is 7.5m. It is self-deployable – it can set itself up on the new surface using its own actuators – and it can mount itself on a mobile rover as well as on the ground. Special purpose tools, such as a bucket, pallet forks, grappling devices, and sensor and visualization packages can be quickly added to the tip using a quick-change device at the tip end.
SARENS Before it can get to the moon, of course, the capsule containing it has to blast off from earth, from the John F. Kennedy space

station, which it will do on top of a 110-metre ‘Space Launch System Block 1’ rocket. The moon program is called Artemis.
Artemis I, an uncrewed test flight, is due to launch this year. Artemis II, a crewed mission around the moon but not landing, is scheduled for late 2023 before Artemis III lands men (and at least one woman) on the surface. To support Artemis II, in the summer of 2021 Sarens was brought in to assist in a crane replacement in the Operations Checkout Building where the Orion capsule is prepared for take-off. The scope of their work was to remove the old 27t High Bay crane that was in place in order to install a new 30t crane which has greater lifting capacity and enhanced controls. The crane is alongside two others, and installing it had its complexities. No headroom was available to allow a crane to perform the lifts from above, so Sarens opted for a hydraulic lift to replace the
equipment from underneath. Teams were able to utilize the old crane for one final lift in order to install the new crane; they then assisted in decommissioning the older model. Project manager Steve Gibson of Sarens
said; “We were brought on by American Crane & Equipment Corporation, which we’ve been working alongside since 2008. NASA provided tremendous support and we’re certain that the Artemis II mission will have an enormous impact on future space travel.”
ERIKKILA Meanwhile back on earth – or rather, back in the sky – Zeppelin is a name to conjure with, redolent of the huge and luxurious airships that crossed continents and oceans before heavier-than-air jet planes consigned them to oblivion. But the Zeppelin company still exists; Count Ferdinand von Zeppelin back in 1915
