Demand exists from users to operate payloads at Lagrange points, but a lack of regular rides results in a deficiency in rideshare opportunities. As a result, such mission architectures currently rely on a costly dedicated launch. NASA and Moog have jointly studied the technical feasibility, risk and cost of using an Orbital Maneuvering Vehicle (OMV) to offer Lagrange point rideshare opportunities. This OMV would be launched as a secondary passenger on a commercial rocket into Geostationary Transfer Orbit (GTO) and utilize the Moog ESPA secondary launch adapter. The OMV is effectively a free flying spacecraft comprising a full suite of avionics and a propulsion system capable of performing GTO to Lagrange point transfer via a weak stability boundary orbit. In addition to traditional OMV ’tug’ functionality, scenarios using the OMV to host payloads for operation at the Lagrange points have also been analyzed. This analysis has led to definition of a mission concept to allow space weather monitoring at the Earth-Sun L1 point as well as perform the technology demonstration of an advanced solar sail payload. INTRODUCTION ~92 million miles ~1 million miles NASA Ames Research Center (ARC), NASA Langley Research Center (LARC) and Moog Incorporated (Moog) have performed initial mission and spacecraft L1 system design enabling a low-cost combined operational and technology demonstration mission at the Sun-Earth L1 Lagrange point (L1). L1 is ideally suited for making observations of the Sun-Earth system given that objects at this location are never shadowed by the Earth or Moon. The motivation for this activity was to offer reduced cost for missions looking to operate at L1 and provide a platform for future development for other missions on the edges and outside of Earth orbit. This mission concept is called Figure 1: Earth Sun L1 Lagrange Point The Example Low-cost Lagrange Investigation Exploration (ELLIE).

For example, in agency in solar sail structures modeling, simulation, July 2012, a massive solar storm missed Earth by one week purely due to the instantaneous position of the structural analysis, and ground validation testing, 3 serving as the structures validation lead for NASA’s Earth with respect to the sun at that time .

Abstract Flight mechanics and control problems associated with the stationing of space- craft in halo orbits about the translunar libration point are discussed in some detail. Practical procedures for the implementation of the control techniques are described, and it is shown that these procedures can be carried out with very small AV costs. The possibility of using a relay satellite in.a halo orbit to obtain a continuous com- munications link between the earth and the far side of the moon is also discussed. Several advantages of this type of lunar far-side data link over more conventional relay-satellite systems are cited. It is shown that, with a halo relay satellite, it would be possible to continuously control an unmanned lunar roving vehicle on the moon's far side. Backside tracking of lunar orbiters could also be realized.

Abstract A Lagrange point of Sun-Earth system, L1 or L2 is conceived one of the best point for astronomy and connection ports for outer planets. This paper describes a new useful control method for realizing and keeping small circular Halo orbits around the L2 point. First, a control law is mathematically derived from the restricted three body problem formulation and the associated properties are discussed. And next, some useful cases for the space mission are verified numerically using real ephemeris. The resulted Halo orbit is compact and circular realized with satisfactorily small thrust.
