(I think I collected most of the important components here.)
Today, let’s talk about how we can reach Alpha Centauri from our Solar system.
What do you think we need to reach there? You want a cool space craft like Enterprise in Star Trek? Yes, we need it definitely. But, before that, we need to analyze the stars to see what is there, and need to understand what we need.
What do you think is the first thing?
Yes, we need to send a probe to see what is there. Do you know how we found the stars in Alpha Centauri? We used the telescope and see the strength of the light. We also can measure the position of the stars from other stars.
But with the telescope, stars will look like only a dot, and we can not know what exactly what we need to prepare to reach there and land.
Most of the magnified pictures for our Solar system we are seeing on the internet are taken by the probes which actually go there close to the planet, take photos, and transmit the data to us.
With the telescope on earth, Mars looks only in this resolution.
This is the picture taken by Subaru Telescope. It is not fine as the pictures Mars probe sent to us.
