Space Technology Course

Lesson 1 • Types of Space Missions

Categorises missions by objective—Earth observation, deep space, crewed, and commercial—and their defining requirements. Sets the scope for mission-specific engineering covered later.

Lesson 2 • History of Space Exploration

Traces the evolution from early rocketry to modern missions, establishing context for current technology. Provides the historical baseline needed for all subsequent technical chapters.

Lesson 3 • Physics of Space Environments

Covers vacuum, radiation, microgravity, and thermal extremes that define the space environment. Understanding these conditions is prerequisite to spacecraft design decisions.

Lesson 1 • Advanced and Electric Propulsion

Covers ion, Hall-effect, and solar sail propulsion for high-efficiency, low-thrust applications. Contrasts these with chemical systems to guide mission-appropriate selection.

Lesson 2 • Launch Vehicle Architecture

Analyses single-stage vs. multi-stage vehicle design, staging events, and payload fairings. Bridges propulsion theory to the integrated launch system perspective.

Lesson 3 • Propulsion Testing and Validation

Describes static fire tests, acceptance testing, and failure mode analysis for propulsion hardware. Establishes quality assurance practices essential before flight certification.

Lesson 4 • Fundamentals of Rocket Propulsion

Explains Newton's third law applied to rocket thrust, exhaust velocity, and the rocket equation. Provides the mathematical foundation for all propulsion performance analysis.

Lesson 1 • Attitude Determination and Control

Explains sensors, actuators, and control algorithms that maintain spacecraft orientation. Accurate attitude control is prerequisite to payload pointing and communication link budgets.

Lesson 2 • Systems Engineering Process

Introduces requirements definition, trade studies, and the systems engineering V-model as applied to spacecraft. Establishes the structured design process used throughout the chapter.

Lesson 3 • Onboard Data Handling

Covers flight computers, data buses, memory management, and fault detection software. Reliable data handling ties all subsystems together into a functioning spacecraft.

Lesson 4 • Power and Thermal Subsystems

Covers solar arrays, batteries, power regulation, and passive/active thermal control. These subsystems set the energy and temperature constraints for all other hardware.

Lesson 1 • Antenna Design and Performance

Covers gain, beamwidth, polarisation, and phased array technology for space applications. Antenna performance is the primary driver of link margin in any satellite system.

Lesson 2 • Electromagnetic Wave Propagation

Reviews radio wave behaviour, free-space path loss, and atmospheric effects on signal quality. This physical foundation is required before any link budget calculation.

Lesson 3 • Frequency Bands and Spectrum Management

Examines L, S, C, X, Ku, Ka, and optical bands, their trade-offs, and international spectrum coordination. Spectrum allocation decisions directly constrain hardware design.

Lesson 4 • Ground Station Infrastructure

Describes ground antenna systems, tracking mounts, baseband equipment, and network connectivity. Ground infrastructure completes the end-to-end communication architecture.

Lesson 1 • Radar and SAR Systems

Introduces synthetic aperture radar principles, polarimetry, and interferometry for surface mapping. SAR provides all-weather, day-night imaging capability unavailable to optical sensors.

Lesson 2 • Image Processing and Analysis

Teaches geometric correction, atmospheric correction, classification, and change detection workflows. Processing transforms raw sensor data into actionable geospatial information.

Lesson 3 • Applications of Earth Observation

Applies remote sensing to agriculture, disaster response, urban mapping, and climate monitoring. Demonstrates the operational value of satellite data across multiple sectors.

Lesson 4 • Principles of Remote Sensing

Explains electromagnetic spectrum interactions with Earth's surface and atmosphere. These physical principles determine sensor design choices and data interpretation methods.

Lesson 1 • Orbit Selection and Trade-offs

Compares LEO, MEO, GEO, HEO, and interplanetary orbits against mission requirements. Orbit selection drives every downstream design decision in a space mission.

Lesson 2 • Interplanetary Mission Design

Introduces patched-conic approximation, gravity assists, and planetary encounter geometry. These techniques enable missions beyond Earth orbit with limited propellant budgets.

Lesson 3 • Delta-V Budget and Manoeuvre Planning

Teaches Hohmann transfers, bi-elliptic transfers, and plane changes with associated delta-V costs. Accurate delta-V budgeting determines propellant mass and launch vehicle selection.

Lesson 4 • Rendezvous and Proximity Operations

Explains Clohessy-Wiltshire equations, phasing manoeuvres, and docking approach corridors. Rendezvous skills are essential for crewed missions, servicing, and debris removal.

Lesson 1 • Spacecraft Commanding and Monitoring

Covers command uplink procedures, telemetry monitoring, limit checking, and trend analysis. These are the core daily tasks performed by spacecraft operations teams.

Lesson 2 • Orbit Determination and Maintenance

Teaches tracking data processing, orbit determination algorithms, and station-keeping manoeuvre planning. Accurate orbit knowledge is required for payload operations and collision avoidance.

Lesson 3 • Anomaly Resolution and Contingency Operations

Presents anomaly investigation processes, safe mode recovery, and contingency procedure development. Rapid, structured anomaly response minimises mission impact and data loss.

Lesson 4 • Mission Control Centre Functions

Describes the roles, consoles, and workflows within a mission control centre during all mission phases. Understanding MCC structure is foundational to all operational procedures.

Lesson 1 • Commercial Space Business Models

Analyses launch services, satellite manufacturing, data services, and in-space economy business models. Understanding commercial structures enables engineers to align technical work with market needs.

Lesson 2 • International Space Law Framework

Reviews the Outer Space Treaty, Liability Convention, and Registration Convention as the legal pillars of space activity. These treaties define state responsibility and operator obligations.

Lesson 3 • National Regulatory Frameworks

Examines how national authorities license launch, satellite operations, and remote sensing activities. Compliance with national regulations is mandatory before any commercial mission.

Lesson 4 • Space Debris and Sustainability Policy

Covers debris mitigation guidelines, active debris removal policy, and long-term sustainability frameworks. Sustainability policy increasingly influences mission design and operational approval.
