Answers
१.Satish Dhawan Space Centre
२. luna २
३.The color of the moon's sky is black during both day and night because there is no atmosphere to color it. During the day, it is simply black to human eyes and normal cameras because the surface is too well-lit for stars to be visible

Answer:
1. Satish Dhawan Space Centre (SDSC) or Sriharikota Range (SHAR) is a rocket launch centre operated by Indian Space Research Organisation (ISRO). It is located in Sriharikota in Andhra Pradesh.
2. Of the Moon landings, Luna 2 of the Soviet Union was the first spacecraft to reach its surface successfully, intentionally impacting the Moon on 13 September 1959. In 1966, Luna 9 became the first spacecraft to achieve a controlled soft landing, while Luna 10 became the first mission to enter orbit.
3.It has no colour. Unlike earth, the moon doesn't have an atmosphere. It is the scattering of sun light in the earth's atmosphere that causes the sky to look blue during the day. At night, in the absence of sunlight, we experience something similar to what the sky always looks like on the moon.
5. With Chandrayaan-2, India hopes to go even farther just as NASA celebrates its own 50th anniversary of the Apollo 11 moon landing by astronauts (Apollo 11 launched on July 16, 1969).
6. 1,737.1 km
7. The world is celebrating the 50th anniversary of the first Moon landing that happened on 20 July 1969 when Eagle module from Apollo 11 landed Tranquility Base. Hours later, Neil Armstrong had his name forever etched in the books of history as the first man to walk on the Moon.
8. A supermoon is a full moon or a new moon that nearly coincides with perigee—the closest that the Moon comes to the Earth in its elliptic orbit—resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from Earth.
4. The Moon orbits Earth in the prograde direction and completes one revolution relative to the stars in about 27.32 days (a sidereal month) and one revolution relative to the Sun in about 29.53 days (a synodic month). Earth and the Moon orbit about their barycentre (common center of mass), which lies about 4,600 km (2,900 mi) from Earth's center (about 72% of its radius). On average, the distance to the Moon is about 385,000 km (239,000 mi) from Earth's center, which corresponds to about 60 Earth radii or 1.282 light-seconds.
