The document describes a project to design and test an extendable electrostatic gripper arm and reactive satellite simulator (RSS) to demonstrate the feasibility of using electroadhesion for satellite capture and manipulation. The gripper arm uses electroadhesion pads which provide mechanical simplicity over traditional docking mechanisms. An RSS with 5 degrees of freedom was also designed and tested to simulate tumbling satellites. Initial testing showed electroadhesion is a viable solution for capturing satellites not designed for docking and could help address issues like servicing and debris removal. Future work aims to refine the arm design and test different gripper pad configurations.
Tidelands Geophysical uses ikeGPSTM mobile GIS systems to efficiently map potential hazards for onshore seismic surveys. Field crews can record locations and photos of obstructions like houses from a distance without trespassing. This allows for more accurate mapping than older systems and less need for re-surveying lines. The ikeGPSTM also streamlines data transfer and processing, saving Tidelands both time and money over previous methods.
Artificial intelligence (AI) is experiencing steadily growing interest over the recent years. For good reason, since these innovative algorithms and methods, such as machine learning and deep neural networks, in which knowledge is acquired and applied based on data, enable the automation of a wide range of processes and quickly deliver precise results. AI is also getting more and more popular in the space sector. The Institute of Space Technology & Space Applications (ISTA) at the Universität der Bundeswehr in Munich is conducting research around AI for space operations, science, and technology. An overview of activities and current developments towards fault management, autonomous collision avoidance, autonomous landing, as well as radio science at ISTA will be presented.
The document discusses anomaly detection in spacecraft telemetry. It describes how the German Aerospace Center monitors over 70,000 parameters from spacecraft like Grace Follow-On and TerraSar X for anomalies. It uses techniques like limit checks, novelty detection, and data analysis to identify issues. The ATHMoS system extracts features from historical telemetry to create a model of normal behavior and detects deviations from this model in new data. Future work includes developing multi-parameter anomaly detection and applying quantum algorithms to problems like spacecraft scheduling and secure data transmission.

Computational fluid dynamics simulations showed the renewable components would not interfere with flight. The goal is to enable long-term environmental monitoring missions across variable terrains.
The document discusses a proposed technology demonstration mission to test electric sail (E-sail) propulsion. E-sails use charged tethers and solar wind to propel spacecraft without propellant. The mission would deploy 16.5 km of tether from a 12U CubeSat at Earth-Moon L1 point. Previous tether missions often failed during deployment, which is identified as the main risk. Three deployment schemes are considered, with a "barbell" design selected for analysis to assess thrusting with charged 16.5 km tethers and steering capabilities. The goal is to advance E-sail technology needed for future missions like faster travel to the Heliopause.

This document summarizes a study that used OpenVSP and Flightstream software to model and simulate the aerodynamic characteristics of wrap-around fins on rockets. OpenVSP was used to model straight fins, wrap-around fins, and wrap-around fins with slots. Simulations in Flightstream showed inaccuracies due to meshing issues and an inability to model supersonic effects. Both tools were useful for subsonic tests but better suited for larger aircraft. Past studies found wrap-around fins caused instabilities like roll reversal in the transonic region. Slots were proposed to alleviate issues but not tested due to simulation limitations.

The simulation was later integrated with a spaceflight simulator for additional testing capabilities. The project achieved its goals of revising the initial specifications and creating a viable demonstration system through simulation.

Altair ProductDesign Case Study - Orion Crew Module Water Landing Simulation for NASA
1. case study
NASA
A Safer Landing for the Orion Crew Module
The Orion Crew Module houses NASA astronauts during space travel and allows them to safely descend back
to Earth from orbit after mission completion. The structural design of the module considered various loading
conditions such as liftoff, launch abort, re-entry and impact landing. It was determined that one of the largest
loading conditions impacting the structure of the Crew Module was an Earth water landing which is a highly
complex and dynamic event. In order to maintain structural integrity and increase safety of the astronaut crew, a
more clear understanding of the dynamic loads generated during water impact was required.
solution
The NASA Engineering and Safety Center (NESC) collaborated with Altair ProductDesign to establish a clear
understanding of the specific modeling methods needed to perform dynamic simulations of the module during a
water landing. In order to ensure that any simulation of the landing accurately matched the real world event, a
limited amount of physical testing was required. NASA fabricated a full scale module and fitted it with various data
collection devices before conducting a total of sixteen physical tests from varying impact angles and velocities.
Using Altair’s own HyperWorks virtual simulation suite, Altair ProductDesign built an accurate finite element
model of the module from CAD data supplied by NASA, as well as a section of water and air which matched the
conditions from the lake used during the physical tests. The effect on the module’s structure during impact was
simulated to gauge how well the results correlated with the physical tests.
result
The results showed excellent correlation between the simulation and physical tests, identifying areas where the
model, input parameters and meshing methods could be improved to give a more accurate prediction of the
event. A mesh sensitivity study revealed that the mesh size ratios of the Crew Module to the fluid were vital in
obtaining a good correlation. The findings from the study will prove invaluable to provide accurate simulation
data for the rest of this ongoing project. With a tried and tested simulation methodology, NASA can be confident
that the simulation results from future development activities are an accurate representation of real world impact
behavior, thus allowing for the development of improved landing safety systems.
