The longest total lunar eclipse of this century would be visible from all parts of the country on July 27. The celestial body would also be tinged with a reddish hue, a phenomenon popularly referred to as a ‘blood moon’. Director, Research and Academic, MP Birla Institute of Fundamental Research, MP Birla Planetarium, Debiprosad Duari told PTI, “Viewers in India are lucky since the eclipse, both partial and the total, will be entirely visible from all parts of the country.”

The eclipse would also be visible in parts of South America, much of Africa, the Middle East and Central Asia, he said. The total lunar eclipse would last for one hour and 43 minutes while partial eclipses, which would precede and follow the total eclipse, would last more than an hour, he said.

The partial eclipse of the moon would start at 11:54 pm Indian Standard Time on July 27 and the total eclipse would begin at 1 am on July 28, Duari said. The scientist said that at 1.52 am on July 28, the moon would look the darkest and it would continue till 2:43 am.

“After this period, the moon will remain partially eclipsed till 3:49 am of July 28. It will be a golden opportunity for celestial enthusiasts in India as the eclipse will be visible almost throughout the night,” he said.

During the July 27 total lunar eclipse, the moon has to pass through the central part of the Earth’s shadow. But on July 27 late night, the Full Moon would be near its apogee, the farthest point from the Earth in its orbit around the Earth, and it would be the smallest full moon of the year.

“This smaller and slower-moving full moon takes more time to cross the Earth’s shadow than does a full moon that is closer to Earth and moving faster in orbit. That is why a full moon at or near lunar apogee adds to the duration of a total lunar eclipse,” Duari said.

The full moon would plunge deeply into the Earth’s shadow on the night of July 27-28 when the distance of the Moon from the Earth just before the eclipse would be around 406,223 kilometre, he said.

During a total lunar eclipse, the Moon’s disk can take on a dramatically colourful appearance from bright orange to blood red and more rarely dark brown to very dark grey, depending upon the part of the Earth’s shadow it would be passing through.

This was the reason a totally eclipsed Moon, at times, was called as Blood Moon. Explaining the celestial phenomenon, Duari said a lunar eclipse takes place only at full moon.

“Whenever, the Sun, Earth and Moon come in a perfectly straight line, as the Sun’s rays fall on the Earth, the Earth’s shadow falls onto a patch of space, and only when the Moon enters that patch of shadow, we see a lunar eclipse,” he said.

Describing 2018, as a year of lunar eclipses, Duari said the last total lunar eclipse took place earlier this year on January 31.

“It was widely known as Super Blue Blood Moon as it was a so-called supermoon when a Moon appears extra big and bright being closest to the Earth in its elliptical orbit. A Blue Moon is the second full moon during a calendar month,” he said.

“The next total lunar eclipse on January 21, 2019, will be only for one hour and two minutes because it will pass to the north of the shadow’s centre,” Duari added.

On whether it will be safe to view the lunar eclipses with naked eyes, Duari said, “No special filters are required to protect our eyes like those used for watching solar eclipses. One does not need a telescope to watch the eclipse, though a good pair of binoculars will enhance the experience.” (IANS)

Private Space Firm SpaceX Will Soon Send First Private Passenger To Moon

The new heavy-lift rocket that NASA is developing for deep-space missions -- known as the Space Launch System -- could serve as a core component of a moon trip.

In a step that commercialises space travel, US private space firm SpaceX on Friday announced that it will send the first private passenger to Moon and will reveal his identity on Monday.

The tourist will fly in the Big Falcon Rocket (BFR) being designed to carry people into deep space, the Elon Musk led company said in a tweet.

“SpaceX has signed the world’s first private passenger to fly around the Moon aboard our BFR launch vehicle — an important step toward enabling access for everyday people who dream of travelling to space.

“Find out who’s flying and why on Monday, September 17,” the tweet said.

The BFR will be used to explore Mars — a goal that Musk hopes to accomplish by 2022.

“SpaceX will probably build 30 to 40 rocket cores for 300 missions over five years. Then the BFR takes over and Falcon retires. Goal of BFR is to enable anyone to move to Moon, Mars and eventually outer planets,” Musk had said in May.

Only 24 humans have been to the Moon so far, and no one has visited since the 1972 Apollo mission.

However, it was not clear whether the BFR tourism mission has any link to an announcement SpaceX made in February 2017, the CNN reported.

At that time, SpaceX said two people signed a deal with SpaceX to make a trip around the moon aboard a Falcon Heavy rocket. SpaceX was tight-lipped about the financial terms of the deal and the identity of the individuals.

In February, SpaceX debuted the long-awaited Falcon Heavy, which became the world’s most powerful operational launch vehicle, the report said.

But during a Falcon Heavy press conference earlier this year, Musk told reporters that, for the time being, SpaceX had no plans to certify the Falcon Heavy for human spaceflight.

Instead, Musk said, SpaceX would turn its focus to developing the BFR, which he deemed a better option for tourism missions.

In December 2017, US President Donald Trump also issued a directive to “lead an innovative space exploration programme to send American astronauts back to the moon, and eventually Mars”.
