Space Exploration and Astronomy

Assemblies containing localized resources are called 'satellite assemblies'. They contain resources specific to a culture or language, allowing applications to be localized without modifying the main assembly.

In .NET, a satellite assembly is a compiled library containing resources (such as localized strings and images) specific to a culture, separated from the main application hub assembly.

Shenzhou 7 was China's third manned space mission and made history in September 2008 when Chinese astronaut Zhai Zhigang performed China's first spacewalk. The mission lasted about 3 days and was a significant milestone in China's space program.

Correct answer is (1). 

PSLV - C14

Cryogenic engines use extremely low temperatures to liquefy gases like oxygen and hydrogen, which are essential as propellants in rocket engines for space exploration. They are not used in Operation Flood (dairy), Atomic Energy, or Operation Research programmes.

The 'space race' was a long lasting competition between the United States and the then Soviet Union between 1957 and 1975. It began with the delivery of the first artificial satellite, Sputnik, into orbit in October 1957. The competition was intimately connected to military superiority as well as general technological superiority.

RH-75 was indeed India's first sounding rocket, launched from Thumba in 1967. It marked the beginning of India's space exploration program and was a crucial milestone in developing indigenous rocket technology. The other options incorrectly attribute this achievement to Pakistan, China, and Japan.

Mars Pathfinder was a NASA mission launched in December 1996 that successfully landed on Mars in July 1997. It included the Sojourner rover, the first wheeled vehicle to explore another planet. Voyager, Discovery, and Columbia were spacecraft with different missions - Voyager for outer planets, Discovery for various missions, and Columbia was a space shuttle.

This is a right answer.  Man used rockets to reach the moon because this is the only best suited means of transport that can reach the moon.

USA (United States) was the first country to send men to the moon with the Apollo 11 mission in 1969. Neil Armstrong and Buzz Aldrin became the first humans to walk on the lunar surface. Russia (then USSR) had earlier sent unmanned probes and was first in space exploration but never landed humans on the moon.

The Soyuz TMA-14 mission carried Guy Laliberte to the ISS in September-October 2009. The mission commander was Gennady Padalka, a veteran Russian cosmonaut, and the flight engineer was Michael Barratt from NASA. The other options list astronauts from different missions or time periods - for instance, Sergei Revin flew on later missions, while Walter Cunningham was an Apollo-era astronaut.

Yes,  Halley's comet was last seen in 1986, this will next appear in after 76 years in the year 2062.

NASA's most important scientific instrument, the Hubble space telescope would begin to fail a few years from now, hence, this sentence emphasizes on its need to preserve this instrument. The clue comes from the word 'even', the clause that follows it provides an explanation to the blank. This implies that though tough tasks have to be undertaken, Hubble Telescope has to be preserved. Hence, (4) is the answer.

A low Earth orbit (LEO) is generally defined as an orbit below an altitude of approximately 2000 kilometres (1200 mi). The Iridium satellite constellation is a large group of satellites providing voice and data coverage to satellite phones, pagers and integrated transceivers over Earth's entire surface. The constellation consists of 66 active satellites in orbit and additional spare satellites to serve in case of failure. Satellites are in low Earth orbit at a height of approximately 485 mi (781 km).
