Leader-Following Attitude Consensus of Multiple Rigid Spacecraft Systems Under Switching Networks
IEEE Transactions on Automatic Control, 2020The leader-following attitude consensus problem of networked rigid spacecraft systems is addressed by a distributed control law. Compared with existing results, the salient characteristic of this work is that the communication network is allowed to be ...

The Giotto spacecraft (Fig. 1), the first ESA (European Space Agency) interplanetary probe, was designed to flyby comet Halley. Launched on 2 July 1985 by an Ariane-1 rocket from Kourou, Giotto succeeded in approaching the cometary nucleus to within 600 km on 14 March 1986. Through its first accurate images of a nucleus and in situ studies of gases and

The Criticality of Spacecraft Index
Advances in Space Research, 2015The future space debris environment will be governed by the production of fragments coming from massive breakups. In order to identify the most relevant parameters influencing the long term evolution of the environment and to assess the criticality of selected space objects in different regions of the circumterrestrial space, a large parametric study ...

Spacecraft exploration of asteroids [PDF]
The past, current, and planned space missions for asteroid exploration are reviewed. The main results based on observations performed with satellites in near-Earth orbits (OAO-2, IUE, FIRSSE, IRAS, HST, Hipparcos, ISO, MSX) and space probes sent to particular objects (Galileo, NEAR, DS1, Stardust) are reported.

Advanced Materials for Next‐Generation Spacecraft
Advances in Materials, 2018Spacecraft are expected to traverse enormous distances over long periods of time without an opportunity for maintenance, re‐fueling, or repair, and, for interplanetary probes, no on‐board crew to actively control the spacecraft configuration or flight ...

Blockchain adoption for information sharing: risk decision-making in spacecraft supply chain
Enterprise Information Systems, 2019This research studies the risk decision-making (RDM) problem faced by participants in a spacecraft supply chain, considering the adoption of the blockchain technology to facilitate information sharing. We investigate a three-level spacecraft supply chain

Space museums are a bit like natural history museums, full of skeletons and stuffed animals: nothing is alive, and if something moves it is usually merely an animated model of the real thing. The exhibition subjects are sometimes shown in simulations of their natural environments, but as hard as it is to capture the wildness of a jungle inside a museum
