[Audio] Over the past few decades the development of space technology for atmospheric and vacuum flight has seen great progress. New methods tools and techniques have been developed for improved safety and efficiency for space travel. In this slide we will examine the different categories of flight plus the related aerothermodynamics. Subsonic and supersonic flights are the most common forms of atmospheric flight. Subsonic flights are those where the speed of the aircraft is lower than the speed of sound while supersonic flights are those where the speed is higher than the speed of sound. Hypersonic flight is an even faster form of flight exceeding supersonic speeds. Vacuum flight is the flight of a spacecraft outside the Earth's atmosphere which necessitates the use of specific technologies. Furthermore Aero-thermodynamics is the study of the flow of gases such as air in and around a spacecraft. According to the table presented the advances made in space technology have made it achievable for aircraft to explore regions of the atmosphere and vacuum that were once unreachable. This has led to a renewed interest in space exploration and to the construction of more advanced technologies for improved efficiency and safety in space travel..

[Audio] This lesson will focus on how space technology has evolved over the past decades including examining Aerospace Safety and the differences small environmental changes can make to the performance of spacecrafts. We will particularly look into the random phenomenon of in-flight atmospheric wind which when combined with external aerodynamic characteristics can induce aerothermal loads that put the launch vehicle at risk of destabilisation during atmospheric flight..

[Audio] For centuries mankind has strived to advance the technology used to explore space. Today space travel is a reality. Aerospace safety regulations and standards have been put in place to safeguard people and property. In this slide we will explore the four main forces that affect a spacecraft as it moves through space: solar radiation pressure luni-solar gravitation atmospheric drag and the asphericity of Earth. Understanding how these forces work is vital for a successful space exploration experience. Our space exploration journey has seen tremendous progress since its inception in the mid-20th century. With strict regulations and highly-developed safety standards space travel is now possible. Here we will explore the forces that affect a spacecraft's trajectory when it moves through space such as solar radiation pressure luni-solar gravitation atmospheric drag and asphericity of Earth. Acquiring a thorough understanding of these forces is key for an efficient and successful space exploration..

[Audio] A good understanding of gravity and escape velocity is paramount for successful space exploration. These equations help us comprehend the distance mass and gravitational force that comes into play in space. With this knowledge of escape velocity we can figure out the minimal velocity required for a body to exit its orbit and reach the stars. Space technology and aerospace safety are core components of space exploration that are needed to achieve these goals..

[Audio] Looking at some of the fundamental equations to understand the process of aerospace safety the radius of the earth is 6378 kilometers the mass of the earth is 5.97 x 1024 kilograms and the gravitational constant is 6.674 x 10-11 Newton meters per square kilogram. These equations provide insight into the gravity around the earth and the forces that impact our aerospace safety..

[Audio] The relationship between escape velocity and circular velocity is related to Newton’s Law of Universal Gravitation. Escape velocity is the minimum speed an object needs to have in order to escape a planet's gravitational pull which is determined by its radius and mass. Circular velocity is the speed an object needs to maintain an orbit around a planet and is also related to the planet’s radius and mass. Both escape velocity and circular velocity can be calculated using the equation R = M x G which expresses the gravitational force between two masses and is proportional to the product of their masses and inversely proportional to the square of the distance between them..

[Audio] We are discussing space technology and its relevance to aerospace safety. To comprehend the basics of space technology and its influence on safety we need to comprehend fundamental equations. For instance the radius of Earth R is 6.5 million meters its mass M is 5.5 x 10^24 kilograms and the gravitational constant G is 6.67 x 10^-11 m^3 per second squared per kg. We can analyze the data tables to work out the circular velocity of the Earth and escape velocity depending on the altitude of the spacecraft from the Earth's surface. For instance for a spacecraft at the Earth's surface the circular velocity is 7.905 kilometers/s and the escape velocity is 11.180 kilometers/s. At 200 kilometers the circular velocity is 7.784 kilometers/s and the escape velocity is 11.009 kilometers/s. Also we can compare these to altitudes of 50000 kilometers 100000 kilometers and the International Space Station's altitude of 357.86 kilometers. This data can help us understand the value of space technology to aerospace safety..

[Audio] Launching from the equator is ideal for zero inclination when sending a satellite into orbit and the desired launch azimuth should be east for north or south polar orbits. Deviating from these conditions can lead to diminished performance which can require additional effort to achieve the desired orbital state..

[Audio] Space technology and safety can be greatly improved by taking advantage of Earth's rotation. Placing launch sites on the east coast is key as the equator's rotational velocity reaches 1670 kilometers per hour. This helps to increase the speed of objects or vehicles that launch from these sites making for more efficient and accurate launches..
