Another Success with CAPSTONE Lunar Mission

Another Success with CAPSTONE Lunar Mission

Spacecraft remains on target to test navigation technology and lunar operations to support NASA’s Moon missions under Artemis programs

It is hard to believe we launched CAPSTONE almost a month ago. We have encountered many variables that have kept this mission exciting, and the mission operators have been active. The Advanced Space Astrodynamics and Navigation Engineers have been busy for years leading up to this and just as busy this last month as CAPSTONE flies. An assumption may be that a small satellite means less work but in actuality the effort is just as great if not more so. Small satellites with small budgets and size restrictions require more creativity and calculated steps to ensure precision and execution through the process. (more…)

CAPSTONE Updated TCM Schedule

CAPSTONE Updated TCM Schedule

The CAPSTONE mission team has rescheduled the trajectory correction maneuver (TCM) originally targeting for this morning to review additional data and perform additional analysis to support modeling of the spacecraft performance during maneuvers. The rescheduled plan does not have any significant impact on the size of the planned correction maneuver which was part of the of TCM executed two days prior.  The spacecraft is healthy, communicating with NASA’s Deep Space Network (DSN) and in a nominal state.

CAPSTONE Mission: 06 July 2022 Update

CAPSTONE Mission: 06 July 2022 Update

Over the last 24 hours, the CAPSTONE mission team has worked together to narrow down the likely cause of the communications systems anomaly discussed yesterday. The integrated mission team took time and care to work the problem, gaining information from various data sources, working with ground-based hardware to evaluate behavior in a controlled environment, and working to resolve the problem systematically.  This work has included rapid engineering support and resources from many different mission partners. We are extremely grateful for this team effort and want to express our appreciation to all of those involved. (more…)

Cislunar Orbit Determination and Tracking via Simulated Space-Based Measurements

Cislunar Orbit Determination and Tracking via Simulated Space-Based Measurements

ABSTRACT

Building on previous work in cislunar orbit determination at Advanced Space, this paper demonstrates cislunar orbit determination via simulated optical measurements from another spacecraft in cislunar space. The goal of this work is to evaluate the potential performance (in terms of the uncertainties in the state of a target object) of space-based optical tracking filters in the vicinity of the Moon.
