NASA Artemis 2: स्टैच्यू ऑफ लिबर्टी से बड़ा है SLS रॉकेट, ये ले जाएगा चारों एस्ट्रोनॉट्स को स्पेस में – what is sls rocket nasa artemis moon mission
NASA is using SLS i.e. Space Launch System rocket for Artemis II mission. This is the world’s most powerful rocket which is specially designed to carry humans into deep space. SLS is a super heavy-lift rocket, that is, it can send very heavy objects out of Earth’s orbit towards the Moon.
Artemis Mission In II, it will send the Orion spacecraft with four astronauts to revolve around the moon. This rocket has been built by combining the old parts of the shuttle program (RS-25 engine and solid rocket booster) with new technology. The first version of SLS is Block 1 which is currently ready for Artemis II.
SLS rocket What are the features of?
The height of SLS Block 1 is 98 meters (322 feet), which is taller than the Statue of Liberty. When fully fueled, its weight is around 57 lakh pounds (2604 metric tons). At the time of launch it produces 8.8 million pounds (39.1 meganewtons) of thrust. This thrust is 15 percent more than Apollo’s Saturn V rocket.
It is equipped with four RS-25 liquid engines (taken from the Shuttle) and two five-segment solid rocket boosters. Liquid hydrogen and liquid oxygen are filled in the core stage. The rocket is too large to be transported on land, so it has to be transported by water by barge. Kennedy Space Center is taken away. The SLS will be upgraded to more powerful Block 1B and Block 2 versions in the future.
How far can SLS take the Orion spacecraft?
SLS Block 1 can take the Orion spacecraft to Trans-Lunar Injection (TLI), i.e. towards the Moon. It can send a mass of 27 metric tons (51525 pounds) into the lunar orbit. In Artemis II, four astronauts sitting in the Orion capsule will go to a distance of 4.50 lakh kilometers from the Moon, which will be the maximum distance covered by humans so far from the Earth.

SLS gives Orion such a high speed that it can travel past the moon and return to its free-return trajectory. In the future, Block 1B and Block 2 versions will be able to carry even more weight (38 to 46 metric tons) to the Moon.
What are the advantages of SLS rocket?
The biggest advantage of SLS is that it has been designed to take humans to the Moon and further to Mars. It provides very high thrust, due to which the heavy Orion spacecraft can be sent into deep space in one go. It has modern safety systems that ensure the safety of the crew.
SLS will also be used for cargo and science missions in the future. This rocket is not reusable, but is very reliable. Based on NASA’s past experience. From this NASA This will help in building a permanent settlement on the Moon and laying the foundation of the Mars mission.

How much time and money did it take to build the SLS rocket?
Development of SLS began in 2011. The first rocket (Artemis I) was launched in 2022, meaning it took about 11 years to complete. The total development expenditure of SLS program has exceeded Rs 2 lakh crore. The cost of each launch is around Rs 21 thousand crores. This figure is only for the rocket, by including Orion and ground systems the entire mission becomes more expensive. NASA is trying to make it cheaper, but the initial launches are very expensive.
How is SLS better than the old Saturn V rocket?
The SLS is an advance on the older Apollo-era Saturn V rockets in many ways. The launch thrust of SLS is 15 percent more than that of Saturn V. SLS is built with modern technology, advanced computers and safety systems. It has been specially designed to land humans on the moon and bring them back.
The Saturn V was intended only for Apollo missions, while the SLS would also be used for future Mars and deep space missions. The SLS uses the shuttle’s old engines, but has been given new control systems and modern materials. Overall, SLS is a more powerful, safer and longer lasting rocket.
