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.
A spacecraft left earth in late 1957 and returned in early 1958. Other than human spacecraft, no alien space craft has ever left or come to visit our planet, that we know of. It is possible some alien space craft may have visited earth millions of years ago. It is highly unlikely any craft has done so within the past few centuries.
Yes, the Earth has been photographed from outer space by astronauts aboard spacecraft like the Apollo missions and the International Space Station. These photographs provide valuable scientific data and also offer unique perspectives of our planet.
There are currently no plans for a Voyager 3 spacecraft. The original Voyager 1 and Voyager 2 spacecraft were launched in the 1970s and continue to send back data from the edge of our solar system. If there were to be a Voyager 3 mission, it would likely be designed for exploring even farther reaches of space.
because "sputnik" means "fellow traveler of earth"

yes
It depends what you mean. The USSR landed several spacecraft there.
No, nobody has travelled to Saturn. However, spacecraft have visited it.
It didn't. Hundreds of thousands of people around the world use it to communicate across linguistic and cultural barriers. It has more speakers now than ever before in its 120 year history, and a thriving international culture, including music and literature. (An Esperantist poet, William Auld, was even nominated for the Nobel Prize in Literature.) Esperanto hasn't yet attained its goal of being the most widely used second language for international communication, but since its beginnings in the 1880s, it has brought millions of people from different cultures together and enabled them to communicate, share ideas and build friendships and even families. It is the only instance of an artificial language transforming into a truly living language. Given that it started as the pet project of an idealistic schoolboy, I'd hardly call that a failure. --------------------------------------------------------------------- Success is arguable, and anything can be declared a success if someone wants it to be. That Esperanto has survived is obvious, and as a SECOND language it could be argued with validity that Esperanto has succeeded. Yet, the question asked why Esperanto failed as a UNIVERSAL language. This contributor has met people from many parts of the world, speaking many languages, and he has never met one who claimed to speak Esperanto. Of all the motion pictures ever filmed, this contributor is aware of only one filmed in the language of Esperanto. To become a secondary language for all people in the world, Esperanto still has a long way to go. ----------------------------------------------------------------------- I would add that several of the claims in the original answer seem questionable. For example, what is the evidence that Esperanto has more speakers than ever? According to the Encyclopedia of Associations, the membership of the Universal Esperanto Association is about 20,000, or half its peak membership. Has the number of speakers increased while the number of members declined? Moreover, it's difficult to imagine a sense in which Esperanto has somehow transformed into a living language while other auxiliary languages have not. Both Interlingua and Ido are used in much the same way as Esperanto. Interlingua has a strong base of speakers, an abundant literature, a radio show, and many prominent writers, such as Giovanni Blandino and prize-winning economist Leland Yeager. At least historically, Ido has been in a similar position, and Volapuk once was as well. Esperanto is one of a few successful auxiliary languages, but it is not the only one.
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.
No human has ever been on Pluto. It is a dwarf planet located in the outer solar system, and no spacecraft designed to carry humans has ever traveled to Pluto. The closest spacecraft, NASA's New Horizons, conducted a flyby of Pluto in 2015.
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
There has only ever been 1 Jewish country: Israel. The national language of Israel is Hebrew.
