Answers

The Voyager Probes’ Golden Records: The Golden Records contain sounds and images selected to portray the diversity of life and culture on Earth. They include 115 images, a variety of natural sounds like thunder and birds, music from different cultures and eras, and greetings in 55 languages. Their primary purpose is to communicate the story of our world to extraterrestrials.
Valentina Tereshkova’s Space Milestone: Valentina Tereshkova piloted the Vostok 6 spacecraft. She was the first and youngest woman to have flown in space, and her mission lasted almost three days (48 orbits around Earth), setting records for the longest solo space mission by a woman at that time.
The Hubble Space Telescope’s Deep Field Image: The Hubble Deep Field image was taken over ten consecutive days in December 1995. This image is significant because it provided a deep view of the universe, showing galaxies billions of light-years away, giving insight into the early stages of the universe.
The Composition of Saturn’s Rings: Saturn’s rings are primarily composed of countless small particles of ice and rock. Theories about their formation include the remnants of a moon that was shattered by Saturn’s gravity, or leftover material from the planet’s formation.
The Mars Rover ‘Curiosity’: The primary objectives of the Curiosity mission were to investigate Martian climate and geology, assess whether the selected field site inside Gale Crater ever offered environmental conditions favorable for microbial life, and search for evidence of water. It discovered ancient organic molecules and provided evidence of past habitable conditions.
The Sun’s Life Cycle: The Sun formed from a molecular cloud about 4.6 billion years ago. Its life cycle includes the main sequence phase (current), followed by expansion into a red giant, then shedding its outer layers to form a planetary nebula, and finally ending as a white dwarf.
The International Space Station (ISS): The ISS serves as a microgravity and space environment research laboratory where scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. It features modules and components from different space agencies worldwide, including NASA, Roscosmos, JAXA, ESA, and CSA.
Neptune’s Wind Speeds: Winds on Neptune can reach speeds of over 2,100 kilometers per hour (about 1,300 mph). These extreme speeds are thought to be caused by Neptune’s high internal heat, which creates convection and atmospheric disturbances.
The Discovery of Exoplanets: The first confirmed detection of exoplanets orbiting a main-sequence star occurred in 1995. The star, 51 Pegasi, was found to have a planet (51 Pegasi b) using the radial-velocity method, which detects variations in the speed with which a star moves toward or away from Earth.
The Kuiper Belt and Its Significance: The Kuiper Belt is a region of the solar system extending from Neptune’s orbit (about 30 astronomical units, AU) to approximately 50 AU from the Sun. It contains small bodies or remnants from the solar system’s formation and is significant because studying these remnants helps us understand the early solar system’s history and processes.
The Pioneer Plaques: The Pioneer Plaques depict a man and a woman, the solar system’s relative location to 14 pulsars, and a schematic representation of the spacecraft. Their intended purpose is to provide information about the origin of the spacecraft for any extraterrestrial life forms that might find them.
Black Holes and Event Horizons: The event horizon of a black hole is the boundary beyond which nothing can escape from the gravitational pull of the black hole. It’s significant because it marks the point of no return, and the laws of physics as we understand them cannot describe what happens inside it.
The Apollo 11 Moon Landing: The Apollo 11 astronauts were Neil Armstrong, Buzz Aldrin, and Michael Collins. The key objectives were to perform a manned lunar landing and return safely to Earth. Armstrong and Aldrin became the first and second humans to walk on the Moon, respectively.
The Cassini-Huygens Mission to Saturn: The mission’s main goals were to study Saturn’s atmosphere, rings, magnetosphere, and its moons, especially Titan. Notable discoveries include finding new rings, evidence of liquid water on Enceladus, and detailed data on Titan’s surface and atmosphere.

Unlike most Earth volcanoes, which are built by many layers of eruptions, Olympus Mons seems to have been built by a few large eruptions.
The First Spacewalk: The first spacewalk was conducted by Alexei Leonov, a Soviet cosmonaut, on March 18, 1965, during the Voskhod 2 mission. One of the major challenges he faced was re-entering the spacecraft as his spacesuit had inflated to the point where he couldn’t fit through the hatch.
The ‘Pale Blue Dot’ Photograph: The photo was taken by Voyager 1 on February 14, 1990, from a distance of about 6 billion kilometers (3.7 billion miles) from Earth. The idea, proposed by astronomer Carl Sagan, was to illustrate Earth’s tiny size and vulnerability in the vastness of space.
