Multispectral satellites are designed to take pictures using different wavelengths of color to capture information about the reflectance of light off landforms. By analyzing this data, scientists can better understand features like vegetation health, soil types, and geological formations.
Scientists typically identify landforms by using a combination of field observations, satellite imagery, topographic maps, and sometimes remote sensing technologies like LiDAR. They look for characteristic features such as shape, elevation, slope, and geology to classify and label different landforms. This process helps scientists understand the natural processes and geological history that have shaped the Earth's surface.
Modern technologies such as LiDAR (Light Detection and Ranging), satellite imagery, drones, and GPS are being used by scientists to measure Earth's landforms and features with higher precision than ever before. These tools provide detailed and accurate data that help in mapping and monitoring changes in landforms, as well as understanding geological processes.
Landsat 7 is the Enhanced Thematic Mapper Plus (ETM+). ETM+ is a passive sensor that measures solar radiation that is either reflected or emitted.

Sea level is measured accurately and consistently across different locations worldwide using a network of tide gauges and satellite altimetry. Tide gauges are instruments that track the height of the sea surface relative to a fixed point on land, while satellite altimetry uses radar to measure the distance between the satellite and the sea surface. By combining data from these sources, scientists can monitor changes in sea level over time and across different regions.
Microwaves are not reflected by the ionosphere because their wavelengths are too short for the ionosphere to effectively reflect them. This is why microwaves are commonly used for satellite communication, as they can pass through the ionosphere to reach satellites in space.
Miranda, one of Uranus' moons, is the satellite that has the greatest variety of landforms observed so far. It has a combination of tall cliffs, deep canyons, and unique geological features that make it an interesting and diverse celestial body.

For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.

The first communications satellite was named Echo 1. It was launched by NASA in 1960 and was a passive satellite that reflected signals back to Earth to demonstrate the feasibility of using satellites for long-distance communications.
The first passive satellite transponder was known as Echo 1, launched by NASA in 1960. It was a large, balloon-like satellite that reflected radio signals back to Earth, enabling long-distance communication.
When the laser light reaches the satellite in a ranging system, part of the light is reflected back towards the Earth. By measuring the time it takes for the light to travel to the satellite and back, the distance between the Earth station and the satellite can be calculated with high precision. This helps in monitoring the satellite's position and orbit.
