VR and AR for Spacecraft Testing and Inspection: Building Quality into the Procedure
Testing is where spacecraft engineering meets reality. Electrical tests, functional checks, vibration campaigns, thermal-vacuum activities and detailed inspections must establish that systems have been assembled correctly and will perform as intended.
These operations can be complex, expensive and difficult to reproduce solely for training.
Virtual Reality (VR) can allow teams to practise test procedures and fault scenarios before equipment is committed to a real campaign. Augmented Reality (AR) can then support equipment identification, setup and inspection during authorised live work.
Learning the Test Environment Before the Campaign
Some test facilities are unfamiliar even to experienced engineers. A team may travel to another site or specialist facility and encounter new access procedures, equipment layouts and emergency arrangements.
A digital twin or representative VR environment allows personnel to familiarise themselves beforehand.
They can learn:
Facility layout.
Restricted zones.
Equipment locations.
Escape routes.
Control positions.
Test sequencing.
Team responsibilities.
Turning Test SOPs into Simulations
A VR training scenario can require the trainee to prepare a test exactly as specified by the customer's procedure.
They may need to identify equipment, verify configuration, establish exclusion zones, complete checks and obtain the appropriate approvals before beginning.
Skipping a mandatory step could prevent the simulated test from proceeding.
This creates procedural discipline without consuming real test-facility time.
Learning to Recognise Anomalies
Training becomes particularly valuable when the simulation introduces faults.
Examples could include:
An incorrect sensor configuration.
A disconnected cable.
Unexpected telemetry.
Equipment outside calibration.
A missing pre-test sign-off.
An alarm during the procedure.
The objective is not necessarily for the trainee to repair the fault. In many procedures, the correct response is to stop, make the system safe and escalate.
VR can assess whether that decision is made correctly.
AR for Inspection
Inspection is another strong AR application because the work is inherently visual and spatial.
An inspector could potentially view the real spacecraft while approved digital reference information highlights:
Inspection locations.
Expected component positions.
Connector references.
Fastener locations.
Areas requiring photographic evidence.
Previous non-conformance locations.
NASA's Roman Space Telescope work demonstrates that registered digital geometry can also help engineering teams assess physical fit and detect interference before further assembly.
AR and Remote Expertise
When appropriate network and security arrangements are available, AR can also connect a technician with a remote specialist.
The expert sees the technician's view and can discuss a specific piece of equipment or inspection point without travelling to site.
This can be valuable when expertise is distributed across organisations or countries.
Standardising Inspection Training
Quality depends on consistency.
If one inspector receives extensive practical coaching while another receives only documentation, training variation can eventually become operational variation.
A bespoke immersive programme provides a common baseline. Each learner faces the same inspection exercise and can be assessed against the same criteria.
Performance data could include missed defects, unnecessary selections, procedural deviations and time taken.
Protecting Expensive Facility Time
Thermal-vacuum chambers, vibration systems and other specialist facilities are valuable assets. Using them for basic familiarisation is inefficient when a digital simulation can address part of that need.
VR cannot replicate every physical sensation or engineering characteristic of a real test campaign, nor should it attempt to replace practical qualification where that is required.
Its value is in making personnel better prepared before those scarce resources are used.
Bespoke Space Test Training
Spark can develop environments around the customer's own facility, spacecraft, EGSE and procedures.
The training may reproduce an entire test campaign or focus on a few high-risk decisions where errors have significant consequences.
The sophistication should follow the operational need rather than technology for its own sake.
Conclusion
Spacecraft testing combines expensive facilities, complex configuration and strict procedural control. VR allows teams to practise that environment without consuming real test time, while AR can connect approved digital information with the physical equipment during inspection and setup.
The combination can strengthen preparation, consistency and fault recognition while reducing avoidable mistakes.
