One advantage of a flyby mission has already been sort of revealed; it's used as a quick initial reconnaissance of something that may later be explored with more expensive and technically difficult missions.
This is true to a large extent, after all why would someone have billions...
This is true to a large extent, after all why would someone have billions spent to determine if there is oxygen present on the moon of a planet in another stellar system when the same funds could be used to finance research and find a cure for diseases that affect and kill a large number of people, or to develop cleaner energy sources, etc.
So if something important was missed, that's kind of too bad.
Unlike a flyby spacecraft, an orbiter spacecraft is a type of spacecraft that enters and stays in orbit around a planet.
For a bit more time and detail, turn to an orbiter spacecraft, a type of spacecraft that enters and stays in orbit around a planet.
For even more data, you can build and use a rover spacecraft, an electrically powered spacecraft that can roam around the celestial object they land on to take detailed pictures, soil samples, and perform other specific tasks for scientific purposes. Our certified Educators are real professors, teachers, and scholars who use their academic expertise to tackle your toughest questions.Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.A disadvantage is that you can't land the orbiter onto the surface of the planet to conduct some more serious scientific experiments.For a more serious investigation, you can turn to a rover spacecraft, an electrically powered spacecraft that can roam around the celestial object they land on to take detailed pictures, soil samples, and perform other specific tasks for scientific purposes.This is like human space missions, programs that send people into space or other celestial objects. The other disadvantage includes possible human death. In fact, the audacious Mars One program, designed to get humans to Mars, is a one-way ticket program only.The ability to have a really good and intelligent peek at other places out in space is one of the advantages of human space missions. If you thought building and operating the rover was costly, then I should point out that the Apollo space program, the one responsible for landing people on the moon, cost over 150 billion in 2014 U. If you want to do a quick reconnaissance of a celestial object, you can perform a flyby, a space mission where a spacecraft passes by a celestial object but isn't held in orbit by it.And if you want, you can always send humans instead of robots, but don't forget it's much more expensive, and real lives are at stake!Remember, human space missions are programs that send people into space or other celestial objects.
