Longest Partial Lunar Eclipse on 19 Nov 2021 Visible in India

The second and Last Eclipse visible from India in 2021 will occur on 19th November 2021. This eclipse is a Partial Lunar Eclipse. Across the world, this eclipse will be visible in the region covering western Africa, western Europe, North& South America, Asia, Australasia, Atlantic Ocean and  Pacific.

Timings of Eclipse& Date: Eclipse in various phases begins at 11.30 am. on 19th November 2021 and Ends at 5.35 p.m. The noticeable Umbral phase begins at 12.48 Noon and Ends at 4.17 p.m. 

In other words: Though astronomically speaking Eclipse begins at 11.30 am. with moon entering the lighter Shadow of Earth called Penumbra and ends at 5.35 p.m leaving Penumbra. People across the world noticeably would witness darkening (or leaving) of Moon’s disk by Earth Shadow in Umbral phase between 12.48 Noon to 4.17 p.m. on 19 November 2021 i.e. which at 3hrs 28 Minutes 23 Secs.

Reason for Being Longest/Lengthiest – Not Visible in Most places: It’s a fact that a Lunar Eclipse occurs when the Moon passes through the shadow of Earth. On 21 November 2021 7.42 a.m. moon will reach the farthest point in its orbit called Apogee. So Eclipse of the Moon on 19 Nov occurs 41 hours before Earth reaching Apogee. Hence as Moon on 19th Nov 2021 is farther away from Earth, it will travel slower along its orbit than at Perigee. In other words Moon near apogee point takes longer to pass through Earth’s shadow making the Partial Eclipse of the Moon on 19 Nov 2021 the longest.

Why Visibility few parts of Assam & Arunachal Pradesh?  The moon rises around 4.24 p.m. in Assam & Arunachal Pradesh whereas the rest of the country Moon rises late. For example like most of the states Moon Rises at 5.43 p.m. in Hyderabad on 19 Nov 2021. Though Eclipse of Moon will occur on 19 Nov in India. Most of the people across India will miss observing this event because Moon rises late and is not above the horizon during the time of eclipse on 19th Nov 2021.  

580 years – 1000 years Social Media Confusion?  Three Lengthiest Lunar Eclipses in 1300 years  – Umbra/Partial phase: Between year 1400 to 2700 three lengthiest “Partial” Lunar Eclipses can be noted i.e 18 Feb 1440 at 3hrs 28mins 46 Sec19 Nov 2021 at 3hrs 28mins 23sec  and on 8 Feb 2669 at 3hr 30mins 02 Secs. This simply means the last time the lengthiest “Partial” Lunar Eclipse occurred was 580 years ago in 1440. Whereas the next lengthiest “Partial” Lunar Eclipse will occur 648 years from Now i.e. in the year 2669.

Names of Moon: In the recent past social media is called Full Moon & allied events with different names. Ex: Full Moon on 19 Nov 2021 is Beaver Moon.  It’s a fact that across the world different folklore name full Moon with different names every month. These Folklore names are based on seasons or astrological reasons. However scientifically speaking natural Satellite of Earth as per International Astronomical Union (IAU) as only one name i.e. Moon.  

The next Lunar Eclipse visible from India which is the Total Lunar Eclipse will occur on 8th Nov 2022. The last lunar Eclipse visible from India occurred on 26 May 2021 which was visible in a few places in India. Whereas the last opportunity to see Lunar Eclipse, for all people across India occurred on 31 January 2018 which was Total. 

NASA's SpaceX Crew-3 Mission Launch 11 NOV 2021 - All the Best Raja Chari, Elon Musk

Live coverage of this launch event with docking, hatch opening and welcoming ceremony etc.. is scheduled from 3.15 a.m. on https://www.nasa.gov/multimedia/nasatv/ . In case of any postponement of the launch on 11 Nov 2021, a backup launch opportunity is planned on 7.10 a.m. IST on November 12.

Astronauts of the Mission visiting International Space Station (ISS) : Present NASA’s SpaceX Crew-3 mission is the third crew flight of the Crew Dragon spacecraft and Falcon 9 rocket developed by Elon Musk-led SpaceX Company. 

This mission consists of NASA astronauts Raja Chari, mission commander, Tom Marshburn, pilot, and Kayla Barron, mission specialist plus ESA (European Space Agency) astronaut Matthias Maurer, who also will serve as a mission specialist, to the International Space Station.

Reaching International Space Station on 12 Nov 2021: If everything goes as planned the Crew Dragon Spacecraft is expected to reach International Space Station at 5.40 a.m. on 12 November 2021.  Live Coverage of Hatch Opening of the Crew-3 Crew Dragon at the ISS, Welcoming Ceremony for the Crew-3 Astronauts Aboard the International Space Station is planned between 5.40 a.m. to 7.50 a.m. on 12 Nov 2021.  PLANETARY SOCIETY, INDIA WISHES ALL THE BEST FOR THE MISSION AND RAJA CHARI FOR HIS MAIDEN SPACE FLIGHT.

What is International Space Station (ISS)?   

The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).  

The space station is approximately the size of a football field. This 460-ton space station orbits earth 400 km above. The crew members of this permanently crewed platform station are replaced through Crew Rotation Missions at regular intervals. Whereas ration & other supplies are sent using unmanned flights.  

Flying at 28 800 km/h around Earth it takes 92 minutes for this weightless laboratory to make a complete circuit of Earth. As of December 2020 in over two decades ISS completed 1,31,440 around Earth @15.49 orbits per day.

WHAT IS US NASA Artemis Programme? 

The Artemis program is a United States-led international human spaceflight program. Its primary goal is to return humans to the Moon, specifically the lunar south pole, by 2024-25. 

Who is ASTRONAUT RAJA CHARI? How was he Selected and Trained to be Astronaut? 

 Raja Jon Vurputoor Chari, 43 is an American citizen of Indian Origin. He is a graduate of the US Air Force Academy, MIT, and US Naval Test Pilot School and has over 2,000 flying hours which includes  F-35, F-15, F-16, and F-18. In July 2017 he was selected from over 18300 applicants to be among 12 Members selected for “NASA Astronaut Group 22” and underwent two years of astronaut training from Aug 2017. 

While November 11 will be the first flight of Chari to space. This U.S. Air Force Colonel still ha
s extensive flight experience. Before reporting to NASA he has flown combat missions in support of Operation Iraqi Freedom and also deployed overseas in support of the Korean peninsula. 

Raja Chari is a person of Indian Origin & an American Citizen. Does he have roots in  Mahabubnagar, Telangana?  

 Raja’s father, Sreenivas Chari, did an engineering degree from Osmania University before moving to America. In 2010 Sreenivas Chari expired. Raja’s grandfather, a native of Mahabubnagar, was a Mathematics professor at Osmania University and died very early in 1955. Raja has visited Hyderabad thrice, where many of his close relatives live.

Will Astronaut Raja Chari Land on Surface of Moon. In NASA's  ARTEMIS Prog or Later?
On 9 December 2020 US Government announced an initial team of NASA astronauts – the Artemis Team consisting of 18 astronauts (9 male and 9 female), for the back to the moon “Artemis” Program. Astronaut Raja Chari was selected to be part of this group of astronauts who will pave the way for the next lunar missions under the Artemis Programme returning Americans Astronauts to the surface of the Moon. Planetary Society India hopes though Raja Chari though selected for initial missions of Artemis Programme may one day land on the surface of the Moon.

52 Formation Day of Indian Space Research Organisation - Hats Off to ISRO Scientists


ISRO's CARDINAL ROLE - OUR TRIBUTES - POOR MAN STARING AT SATELLITE LAUNCH- IGNORANCE: Just like this poor man staring at Satellite Launch wondering. Why do these Scientists Launch these rockets.. Many of us including the educated still are not aware of the role of the Indian Space Program in our Life.It is fact that the benefits of the Space Program, for that matter full potential of Science & Tech haven't yet full reached many even after 75yr.

15 Aug Independence Day Celebrations - 75th Year Celebrations

Picture Shot at Satara, Maharashtra Credits: to Unknown Photographer
We at Planetary Society India Wish you all a Happy Independence Day . The 3 colours in this pic (Satara, Maharashtra) are an inseparable part of Nature. In today world of Polarisation Politics, this pic conveys the important message "United We Stand, Divided we Fall". See Explanation below 

1.The tri colours of the Indian flag have deeper & greater meaning. click/read/visit https://bit.ly/15tricolor

2.Imperialists easily ruled the country with Divide & Rule Policy. Unfortunately, POLARISATION in various forms has become a key factor in Elections Politics. Efforts are made to prove "one colour among other 3 colours" are "Better than others" &  "Separable". 

3.Even if people misunderstand Saffron, White&Green.This real natural pic shot at Satara, Maharashtra Poetically/Metaphorically indicates: THESE COLOURS ARE INSEPARABLE & ESSENTIAL PART OF NATURE. 


i) Sunlight energises creatures on Earth. Its first rays inspire hope. 

ii) White clouds carrying water vapour delivers the Waterđź’§during monsoon. 

iii) Greenery of crops, trees, plants provides food & fresh air. 

So It's essential to understand Unity in Diversity is the strength of India. Efforts for National Integrity are the need of the hour

SPOT MOON WITH SATURN & JUPITER ON 24, 26 July - Are they Really Close as claimed in Viral Reports on the Web ?


In Scientific terms 



In simple words, the Appearance of one or more celestial bodies together in the sky is known as Conjunction. Interestingly though Moon & Planets appear near each other, in reality, they are separated by enormous distances. 

Visibility - Opportunity to Use Moon to Spot Planets: Every month with help of the Moon  3-4 times we can spot planets. Like today on 24July Saturn would appear like a dim non-twinkling star-like object besides Moon. Similarly, on 26 July Jupiter can spot near Moon like a bright non-twinkling star-like object.

Importance?  It's fact that the average Distance between Moon And Earth is 3,84,400km. Whereas the Distance between Moon and Saturn or Jupiter varies by millions of kilometers. But in spite of the enormous distance appearance of the Moon closer to Saturn (on 24 July) or Jupiter (on 26July) makes it easy for observers to identify or spot planets easy.

However, linking celestial events to natural events on earth or Social/political events of a country or individual looking for life is unscientific. 

How exactly does coming together appear to happen?

We all know Moon goes around Earth. But an observer in his sky will see Moon in different phases (Example: Crescent Moon etc) every consecutive evening. And also, the observer would witness Moon at a new location in his sky in the background of a new set of stars or planets than the previous night. 

The specialty of Buck Moon? Does it make any difference?

Scientifically speaking There is nothing special when Full Moons are called with different names. Such naming is a cultural or traditional practice. In India Full moons are known as Guru Purnima, Kartika Purnima etc.. Similarly in Western folklore Buck Moon, Pink Moon is the name given based on seasons. 

Further additional Brightness or bigger appearance of Moon mainly depends on distance (perigee/apogee) of Moon to Earth at time of the full moon


On 22 July 2019 at 2.43p.m IST Chandrayaan 2 Mission was launched on its journey towards Moon along with its Orbiter, Vikram Lander & Pragyan Rover. While everyone knows what happened to Vikram Lander on 7 Sept 2019. Chandrayaan 2 Orbiter is still working going around Moon. The Orbiter was actually planned to work for 1 year but in a written response to a question in parliament Union Minister Jitendra Singh stated ISRO expects Chandrayaan to work for 7 Years. Similarly, Mars Orbiter Mission (MOM) or Mangalyaan launched on 5 Nov 2013 was originally planned to work for 6 months, but even after 7 years it's still working going around Mars. 

GSLV MK III-M1 Launch vehicle With Chandrayaan 2 on 22 July 2019 2.43 p.m IST

OUR CALCULATIONS BASED ON AVAILABLE DATA - FOR ACTUALS CONTACT ISRO: As per the latest information Chandrayaan-2 orbiter is orbiting around the  Moon in a polar orbit at an altitude of 100 km from the Moon Surface. Based on the last available Orbital Period data. Chandrayaan 2 Orbiter has completed 8800 Orbits around Moon i.e. 12 Orbits in every 24 hours. This means it takes approx 2 hours for Chandrayaan 2 to complete one orbit around Moon.
