Today, science has progressed a lot. Five countries have reached the Moon, America has even landed a man on the Moon years ago, but still one thing has not changed, the time to go to the Moon. Even after progress, it takes at least three days to reach the Moon with the help of the fastest rocket. At most, don’t ask, it may take months. Why is it that it takes so much time to reach the moon that we see every day?

आज की तारीख में विज्ञान ने काफी तरक्की कर ली है। चांद पर पांच देश पहुंच चुके हैं, अमेरिका तो सालों पहले चांद पर इंसान तक उतार चुका है, लेकिन फिर भी एक चीज नहीं बदली, चांद पर जाने का समय। तरक्की के बाद भी चांद पर तेज से तेज रॉकेट के सहारे में जाने में कम से कम तीन दिन लग जाते हैं। ज्यादा से ज्यादा तो पूछिए मत, महीने भी लग जाते हैं। आखिर ऐसा क्यों हैं कि जिस चांद पर हम रोज देखते हैं, वहां पहुंचने में इतना समय लग जाता है।

धरती से चांद का सफर

अंतरिक्ष यान को चंद्रमा तक पहुंचने में लगभग 3 दिन लगते हैं। इस दौरान अंतरिक्ष यान कम से कम 240,000 मील (386,400 किलोमीटर) की यात्रा करता है जो पृथ्वी और चंद्रमा के बीच की दूरी है। विशिष्ट दूरी चुने गए विशिष्ट पथ पर निर्भर करती है।

journey from earth to moon
The spacecraft takes about 3 days to reach the Moon. During this time the spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between the Earth and the Moon. The specific distance depends on the specific path chosen

वर्तमान में धरती से चांद की दूरी

धरती से चांद की दूरी घटती बढ़ती रहती है। पृथ्वी से चंद्रमा की दूरी वर्तमान में 404,398 किलोमीटर है, जो 0.002703 खगोलीय इकाइयों के बराबर है। प्रकाश को चंद्रमा से यात्रा करके हम तक पहुंचने में 1.3489 सेकंड लगते हैं।

Present distance of the Moon from the Earth
The distance of the Moon from the Earth keeps increasing and decreasing. The distance from Earth to the Moon is currently 404,398 kilometers, which is equal to 0.002703 astronomical units. Light takes 1.3489 seconds to travel from the Moon to reach us.

चांद पर कैसे पहुंचा जा सकता है

चांद पर पहुंचने के लिए, सबसे पहले आपको रॉकेट में काफी तेज़ गति से यात्रा करके पृथ्वी के गुरुत्वाकर्षण से बचना होगा। जिसके लिए रॉकेट की रफ्तार कम से कम 25,000 मील प्रति घंटा होना चाहिए। एक बार जब आप पृथ्वी की कक्षा में पहुंच जाएं, तो अपने प्रक्षेप पथ को बदलने और चांद की ओर जाने के लिए थ्रस्टर्स को फायर करके आगे बढ़ सकते हैं।

how to reach the moon
To reach the moon, you must first escape Earth’s gravity by traveling at very high speed in a rocket. For which the speed of the rocket should be at least 25,000 miles per hour. Once you reach Earth’s orbit, you can fire the thrusters to change your trajectory and head toward the moon

चांद पर पहुंचे में कितना समय लगता है

नासा ने चंद्रमा पर आठ चालक दल वाले अपोलो मिशन भेजे, जिनमें से छह सफलतापूर्वक उतरे। प्रत्येक ने इस दौरान लगभग तीन दिन यात्रा करने में बिताए। अपोलो 8 को चंद्रमा की कक्षा में प्रवेश करने में 69 घंटे और 8 मिनट लगे। अपोलो 11, जिसने पहले मनुष्यों को चंद्रमा पर भेजा था, को चंद्रमा की कक्षा में प्रवेश करने में 75 घंटे और 56 मिनट लगेअपोलो 11 के लिए, यह 61 घंटे और 56 मिनट के बाद हुआ, जबकि अपोलो 8 के लिए इसमें केवल 55 घंटे 40 मिनट लगे।

how long does it take to reach the moon
NASA sent eight crewed Apollo missions to the Moon, six of which landed successfully. Each spent about three days traveling during this period. Apollo 8 took 69 hours and 8 minutes to enter lunar orbit. Apollo 11, which sent the first humans to the Moon, took 75 hours and 56 minutes to enter the Moon’s orbit. For Apollo 11, this happened after 61 hours and 56 minutes, while for Apollo 8 it took only 55 hours 40. It took minutes

भारत के चंद्रयान-3 ने कितना समय लिया

14 जुलाई 2023 को चंद्रयान-3 को LVM3 पर सफलतापूर्वक लॉन्च किया गया और 5 अगस्त 2023 को इसे चंद्र के गुरुत्वाकर्षण क्षेत्र में डाला गया। 23 अगस्त 2023 को, लैंडर विक्रम ने चंद्र के दक्षिणी ध्रुव क्षेत्र में सफलतापूर्वक लैंडिंग की। मतलब भारत के चंद्रयान 3 को चांद पर पहुंचने में एक महीने से ज्यादा का समय लगा।

How much time did India’s Chandrayaan-3 take?
On 14 July 2023, Chandrayaan-3 was successfully launched on LVM3 and on 5 August 2023, it was inserted into the lunar gravity field. On 23 August 2023, lander Vikram successfully landed in the lunar south pole region. Meaning, India’s Chandrayaan 3 took more than a month to reach the moon

सबसे तेज रॉकेट

अपोलो 10 अभी भी किसी भी मानव द्वारा यात्रा की गई सबसे तेज गति का रिकॉर्ड रखता है, जब इसकी अधिकतम गति 24,791 मील प्रति घंटे (39,897 किलोमीटर प्रति घंटे) दर्ज की गई थी, जबकि अपोलो 10 के चालक दल ने पृथ्वी के सापेक्ष 24,791 मील प्रति घंटे (39,897 किलोमीटर प्रति घंटे) की गति से यात्रा की थी, जब वे 26 मई, 1969 को पृथ्वी पर वापस आए थे।

fastest rocket
Apollo 10 still holds the record for the fastest speed traveled by any human, when its maximum speed was recorded at 24,791 mph (39,897 kph), while the Apollo 10 crew reached 24,791 mph relative to Earth. They traveled at a speed of 39,897 kilometers per hour (16,000 mph) when they returned to Earth on May 26, 1969.

सबसे तेज और सबसे धीमा मिशन 

सबसे तेज़ अपोलो मिशन (अपोलो 8) को चंद्रमा तक पहुंचने में 69 घंटे और 8 मिनट लगे, जबकि सबसे धीमे (अपोलो 17) को 86 घंटे और 14 मिनट लगे थे।

fastest and slowest missions
The fastest Apollo mission (Apollo 8) took 69 hours and 8 minutes to reach the Moon, while the slowest (Apollo 17) took 86 hours and 14 minutes.

Based on past missions, we know that it usually takes about three days for a manned spacecraft to reach the moon when the average distance from Earth to the moon is 240,000 miles (386,243 kilometers). This translates to a spacecraft’s speed of about 3,333 mph (5,364 kph). Yet, the duration isn’t always set in stone

Why does it take 3 days to travel to the moon?

It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen

Why does Chandrayaan-3 take 42 days?

India’s Chandrayaan-3 mission will reach the Moon after a journey of over 40 days, in contrast to NASA’s Apollo 11, which arrived at the lunar surface in just four days. This is because Chandrayaan-3 employs a slower, more gradual trajectory than the direct Translunar Injection used by the Apollo missions

Why haven’t we gone back to the moon?

‘In 1972, the budget of NASA was dramatically shrunken and there was no more political interest for further crewed missions to the moon, or even build a moonbase

Why does it take longer to get to the Moon than to get back?

If you are not reusing your rockets and spacecraft, you will lose mass along the way as you leave behind spacecraft that you no longer need. This means that the return trip will have less mass than the trip out. This was the case during Apollo. On the way to the Moon they had to carry the Command and Service modules as well as the two-part Lunar Module from the Earth and then slow all these spacecraft down to be captured into lunar orbit. The faster these spacecraft flew to the Moon, the more fuel it would take to slow them down into lunar orbit. This meant a slower speed would require less fuel to get into lunar orbit. And since every pound counts, it made sense to travel out to the Moon relatively slower.

After landing on the Moon, they left the Lunar Module landing stage on the lunar surface and the ascent stage in lunar orbit (temporarily) when they departed. Only the Command module and Service module (with much of its fuel already used) made the trip back to Earth. This was much less mass to accelerate out of lunar orbit so they were easily able to attain a higher velocity on the return trip, which meant a shorter trip returning home than their trip out to the Moon.

Why is it taking so long to go to the moon compared to the 60s?

Three reasons.

1. Money. If you spend less money, it takes longer (because the other option, a shoddy result, is not really acceptable here).
2. Risk. The first Apollo expedition was estimated to have a 50% chance of succeeding, which everyone involved felt was acceptable. And the other 50% meant the astronauts died.
3. Ambition. No one is interested in just putting someone down on the surface and getting them back, because that’s been done and there’s a limited return on that investment. The idea now is to go there with the ambition to build a permanent base.

When you do something that’s ten times as complicated, you want it ten times as safe, and you only spend one tenth of the money – and you want to spend it on more things besides, which wasn’t the case in the 1960s – the only thing left to compromise with is time.

According to NASA, a one-way trip to the Red Planet would take about nine months. If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.

NASA’s Artemis program is a multi-billion dollar space program that aims to send astronauts to the moon and establish a permanent presence there. The program consists of a series of increasingly complex missions that will lay the foundation for sustainable human and robotic exploration of the moon. 

The Artemis missions include:

• Artemis I An uncrewed test flight of the Orion spacecraft that orbited the moon 130 km above the surface and traveled 450,000 km to deep space. 
• Artemis II A mission that will test life support systems by sending a space crew around the moon for a 10-day expedition. This mission is scheduled to launch no earlier than September 2025. 
• Artemis III The first crewed mission to land astronauts on the moon, which is scheduled to launch in September 2026. The crew will visit the moon’s south pole to search for water, study the surface, test technologies, and learn to work on a world outside Earth. 

NASA also plans to land a second crew on the moon in 2028, establish a Lunar Gateway station where astronauts will land in 2029, and eventually set up a permanent base on the moon.
