The Galileo spacecraft has sent back tantalizing image data hinting at a vast ocean beneath a thick ice crust on Europa, one of Jupiter’s moons which is about the size of our moon. NASA plans to establish definitively whether this ocean exists with

We describe an integrated instrument that will perform the functions of three optical instruments required by a Pluto Fast Flyby mission: a near-IR spectrometer (256 spectral channels, 1300–2600 nm), a two-channel imaging camera (300–500 nm, 500

An adaptive truss manipulator (ATM) space crane concept for in-space assembly and construction is described in this paper. The underlying mechanism of ATM operation is based on the geometric transformation of its constituent truss modules. In this pa

An active damping augmentation approach using active members in a structural system is described. The problem of maximizing the vibration damping in a lightly damped structural system is considered using the analogy of impedance matching between the

Future NASA missions will require large space structures that must maintain accurate surface tolerances for up to 20 years; most flight programs require a ground test verification of the hardware. Because of the influence of gravity, the current stat

Active structural members with built-in sensing, feedback control, and actuation functions are used herein, along with passively damped members, to augment the inherent damping in truss structures. The effective use of such members makes it desirable
