Yes. According to Pale Blue Dot, ISBN 0-7472-1553-7 p.152, by Carl Sagan, the two Voyager spacecrafts each contained "a golden phonograph record encased in a golden, mirrored jacket containing, among other things: greetings in 59 human languages, and one whale language". If you listen to track 3 (UN Greetings) between 2m 16s and 2m 24s you can hear the Esperanto greeting "Ni strebas vivi en paco kun la popoloj de la tuta mondo, de la tuta kosmo" (We strive to live in peace with the peoples of the whole world, of the whole cosmos) by Ralph Harry (see the related link). Listen in the related links.

Launched by the Saturn 5 rocket (the largest rocket ever built), the first spacecraft to take men to the moon was the Apollo spacecraft.
Yes. Apollo 11 was the first Apollo mission to successfully land on the moon, but it was not the first ever US spacecraft to land on the moon, though it was the first spacecraft to successfully carry people to the moon.
Very doubtful, NASA has no official plans for a Voyager 3 mission so far, and I doubt they ever will. If they ever do launch Voyager 3, it won't be for a while.
As far as is known to the public, no man-made object has ever landedon Mercury.The MESSENGER spacecraft flew by Mercury to gather data on the planetonce in 2009, and once again in early 2010.1

It depends what you mean. The USSR landed several spacecraft there.
No, nobody has travelled to Saturn. However, spacecraft have visited it.
No person has ever been to Mars. No spacecraft has ever surveyed Mars and returned to earth. No spacecraft has ever landed on Mars and lifted off again. No liquid water has ever been observed on Mars, and no samples have ever been removed from its surface. In conclusion, we frankly don't know what the question is talking about.
Esperanto failed to become a universal language mainly due to lack of widespread adoption and support from governments and institutions. Additionally, the dominance of English as a global lingua franca has made it challenging for Esperanto to gain traction as a widely accepted language for international communication. Critics also argue that the perceived lack of cultural richness and historical depth in Esperanto may have hindered its appeal.
No spacecraft from Earth has ever landed on Neptune.
No human has ever landed on Venus. Spacecraft have been sent there, but due to the conditions they do not last very long.
No, but a space probe called New Horizons is on its way for a flyby.
Up to mid-2011, nothing has ever yet been "made" in a spacecraft that wasn't carried in it at launch, with the possible exception of electrical power. That includes air and water.
nobody ever landed on Jupiter
No.
