Assuming you mean a machine for landing on other planets and moons... One of the biggest disadvantages is that landers have to be built to be very tough to survive entering the planet's atmosphere at several kilometres per second speed. There is quite a big chance that the lander won't make it, a big disadvantage when you consider how many millions it costs to build the lander...
The purpose of life is a complex and subjective question that varies for each individual. Some may find purpose in personal growth, relationships, helping others, or pursuing passions and goals. Ultimately, the purpose of life is to find meaning and fulfillment in one's existence.
Earthquakes don't really have a purpose; they just happen. "Purpose" implies that the said process can be useful. Rain also occurs naturally, but we use it to cultivate fruits and vegetables. You could say that is its "purpose." Earthquakes, on the other hand, aren't useful to us at all. They can cause massive damage and the kinetic energy involved cannot be harnessed.
The purpose of convection is to transfer heat from one place to another through the movement of fluids (liquids or gases). This process helps distribute heat more evenly in a space, such as in a room with a radiator or in the Earth's atmosphere through weather systems.
The lander was used to land on planets and study the such as the moon and the orbiter was used to orbit the planet while studying it.
