Q1. What is the name of the Russian space program’s tradition of giving cosmonauts a special “space flight patch” to commemorate their mission?
-
A. A patch that represents the mission’s launch site
-
B. A patch that shows the Earth from space
-
C. A patch that displays the cosmonaut’s personal name or initials
-
D. A patch that features a unique design created by the cosmonaut themselves ✓
Explanation: In the Russian space program, cosmonauts are given a special space flight patch to commemorate their mission. This patch is a unique design created by the cosmonaut themselves, and it is a tradition that dates back to the early days of space exploration.
Q2. What is the typical length of a Russian cosmonaut’s expedition aboard the International Space Station?
-
A. Up to 30 days
-
B. About 6 months, sometimes extended toward a year ✓
-
C. Always exactly one year
-
D. Several years
Explanation: Standard ISS expedition rotations run roughly six months; a few missions have been extended to roughly a year (e.g., Polyakov-era and Kelly/Kornienko-style missions are exceptions, not the norm).
Q3. Which of the following is a unique challenge that cosmonaut Alexei Leonov faced during the first spacewalk in 1965?
-
A. He had to deal with a stuck spacesuit valve. ✓
-
B. He experienced a rapid loss of oxygen in his suit.
-
C. He had to navigate through a space debris field.
-
D. He had to endure extreme temperatures in his spacesuit.
Explanation: Alexei Leonov's spacesuit inflated in the microgravity environment, making it difficult for him to re-enter the spacecraft. He had to manually vent the air from his suit to avoid getting stuck.
Q4. Which of the following astronauts was the first woman to walk in space?
-
A. Sally Ride
-
B. Valentina Tereshkova
-
C. Svetlana Savitskaya ✓
-
D. Peggy Whitson
Explanation: Svetlana Savitskaya was a Soviet cosmonaut who became the first woman to perform a spacewalk on July 25, 1984, during the Salyut 7 mission.
Q5. What is the primary physiological challenge astronauts and cosmonauts face in space due to microgravity?
-
A. Changes in the digestive system due to the lack of gravity.
-
B. Fluid shifts in the body that affect blood pressure and other functions. ✓
-
C. Muscle atrophy due to reduced weight-bearing activities.
-
D. Difficulty in seeing due to the dim lighting on the International Space Station.
Explanation: In microgravity, fluids in the body shift upwards, leading to changes in blood pressure, affecting the cardiovascular system, and causing other physiological adaptations. This is a significant challenge for astronauts.
Q6. Which of the following astronauts was the first woman to perform a spacewalk?
-
A. Sally Ride
-
B. Valentina Tereshkova
-
C. Svetlana Savitskaya ✓
-
D. Peggy Whitson
Explanation: Svetlana Savitskaya was a Soviet cosmonaut who performed the first spacewalk by a woman on July 25, 1984, during the Soyuz T-7 mission.
Q7. Which of the following astronauts was the first woman to fly on the Soyuz spacecraft?
-
A. Valentina Tereshkova
-
B. Svetlana Savitskaya ✓
-
C. Yelena Kondakova
-
D. Anatoli Solovyov
Explanation: Svetlana Savitskaya was a Soviet cosmonaut who flew on the Soyuz T-7 mission in 1982, becoming the first woman to fly on a Soyuz spacecraft.
Q8. Which of the following women was the first to perform a spacewalk?
-
A. Sally Ride
-
B. Valentina Tereshkova
-
C. Svetlana Savitskaya ✓
-
D. Yelena Kondakova
Explanation: Svetlana Savitskaya, a Soviet cosmonaut, became the first woman to perform a spacewalk in 1984, outside the Salyut 7 space station.
Q9. What is the primary reason why astronauts and cosmonauts wear pressurized suits during spacewalks?
-
A. To protect them from extreme temperatures
-
B. To prevent the loss of oxygen
-
C. To maintain a safe internal body pressure ✓
-
D. To avoid radiation exposure
Explanation: Astronauts and cosmonauts wear pressurized suits during spacewalks to maintain a safe internal body pressure. This is because the pressure outside the space station or spacecraft is much lower than the pressure inside the human body, and if the suit is not pressurized, the gases in the body could expand and cause damage.
Q10. What is the primary reason why astronauts and cosmonauts are required to wear pressurized suits during spacewalks?
-
A. To protect themselves from extreme temperatures in space
-
B. To prevent their bodies from expanding in the microgravity environment
-
C. To prevent the loss of oxygen and moisture from their bodies ✓
-
D. To protect themselves from harmful radiation in space
Explanation: Astronauts and cosmonauts wear pressurized suits during spacewalks to prevent the loss of oxygen and moisture from their bodies. This is because the suits maintain a safe internal pressure, preventing fluids from escaping and reducing the risk of dehydration and hypothermia.
