The Indian Space Research Organisation (ISRO) on Monday put Emisat — an electronic intelligence satellite for the Defence Research and Development Organisation (DRDO) — and 28 other foreign satellites into orbit in a copybook style.
With Monday’s launch, India has successfully put into orbit 297 foreign satellites to date.
So far, Polar Satellite Launch Vehicle (PSLV) rocket has put into orbit nation’s 46 satellites, including 10 satellites built by students from Indian universities.
Notable aspects of this space mission are the flying of a new variant of PSLV, switching off and on the fourth stage engine couple of times and the use of the fourth stage as an orbital platform carrying three experimental payloads.
After the successful launch, space agency’s Chairman K. Sivan said: “Today the PSLV has successfully injected the ISRO-made Emisat satellite into its intended orbit and 28 customer satellites at a 504-km altitude.
“The mission is special for the ISRO on many counts as it was the first time a PSLV rocket was launched with four strap-on motors; the mission has three different orbits for the very first time; the fourth stage was made an orbital platform for experiments; and there was also a new team for the PSLV.”
Sivan said the industry contributed a lot for the building of the rocket and satellite.
“Ninety-five per cent of the rocket hardware and 60-65 per cent of satellite components were fabricated by the industry,” he said.
At 9.27 a.m, the PSLV rocket standing at 44.5 metres tall and weighing 239 tonne with a one-way ticket, hurtled itself towards the skies.
With the fierce orange flame at its tail lighting, the rocket slowly gathered speed and went up.
Heeding to the demand of the public to view the rocket launch, Sivan said that a viewers’ gallery was built and 1,200 people enjoyed spectacle.
He said for the next mission about 5,000 people will be allowed to witness the launch.
The PSLV is a four-stage engine expendable rocket with alternating solid and liquid fuel. In its normal configuration, the rocket will have six strap-on motors hugging its first stage.
On January 24, the ISRO flew a PSLV with two strap-on motors, while in March, it had four strap-on motors.
The space agency also has two more PSLV variants — Core Alone (without any strap-on motors) and the larger PSLV-XL.
The ISRO selects the kind of rocket to be used based on the weight of satellites it carries.
Forty-seven seconds after the launch, the Emisat was ejected at an altitude of about 753 km.
Meanwhile, at about 60 minutes after the PSLV’s lift-off, its fourth stage was restarted and run for about 10 seconds before it was cut off again.
At about 108 minutes after the lift-off, the rocket’s fourth stage was again restarted for few seconds before it was again cut off.
Finally, at about 110 minutes, the first of the 28 foreign satellites were ejected and in five minutes, they were put into orbit.
Later, the fourth stage was restarted and stopped twice to bring its altitude to 485 km at the end of three hours after the lift-off.
At this point, the fourth stage began its role as the orbital platform for three experimental payloads: (a) Automatic Identification System (AIS) from ISRO for Maritime satellite applications capturing messages transmitted from ships (b) Automatic Packet Repeating System (APRS) from AMSAT (Radio Amateur Satellite Corporation), India – to assist amateur radio operators in tracking and monitoring position data and (c) Advanced Retarding Potential Analyser for Ionospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) – for the structural and compositional studies of ionosphere, the space agency said.
As regards future missions, Sivan said the next PSLV rocket will carry RISAT and it will be followed by another PSLV launch carrying Cartosat-3 satellite.
India will also launch two more defence satellites some time in July or August with its new rocket Small Satellite Launch Vehicle (SSLV). (IANS)
Drawn from the details provided by a Brahmin-turned-amateur-historian, this is a real story that follows two learned men as they traverse India during the 1857 uprising on foot, unearthing history from a new vantage point
As the First War of Independence raged, a Brahmin from Maharashtra, Vishnubhat Godse, on a pilgrimage found himself caught right in the middle of the action. He, along with his uncle Rambhat, went through a series of adventures, including barely escaping hanging.
Upon his return home, Godse wrote it all down in Marathi so that his forthcoming generations could have an idea of how things were during that tumultuous period. "The Walking Brahmin" by Maneesh Madhukar Godbole retells that journey, which is a rare eyewitness account from a common Indian's point-of-view.
Published by Garuda Prakashan decades after the original manuscript, it puts all pieces of the story together with maps and photographs and offers a unique insight into what really happened during the War of 1857.
This tale starts in 1857, as the protagonist duo starts on a 'teertha yatra' from Varsai, a small Maharashtrian village, and walk smack in the middle of the mutinous upheaval of 1857. Having the misfortune of being at the wrong place at the wrong time, they were caught in the crossfire between the loyalist Indian troops and the British.

Narrativising historical incidents through an Indian lens, such as the fall of Jhansi, they survived the aftermath of British savagery, were robbed of all their belongings multiple times, and even managed to avoid getting hanged twice. Being on the road for over two years, they finally returned to Varsai, which was where Vishnubhat penned down his adventure for his descendants.
"His original manuscript, which ran into 297 pages, comprised two notebooks and twenty-two individual pages. It was eventually published as a Marathi book in 1907, a few years after Vishnubhat's death. This is probably the only known instance of a document that talks about 1857 from an Indian perspective," the Pune-based Godbole said.
"Not only does it give us the story from the perspective of the vanquished, but it is also more reliable as it is a first-hand account of experiences and not based merely on hearsay. Thus, the value of this book, in the annals of history, is quite priceless.
"Vishnubhat's book offered me a unique and authentic insight on how our ancestors lived. What they believed in, the social structure of those times, the hardships, the never-give-up attitude, their fortitude, their beliefs and their ability to even put their lives at risk to fulfill their responsibility," added Godbole, who learnt about this lesser-known story when he was busy writing blogs related to his travel to northeast India and subsequent research.
Sharing his insights on the book, Uday S. Kulkarni, historian and author of "The Extraordinary Epoch of Nanasaheb Peshwa", said that it "gives us a graphic account of the cruelty perpetrated by British forces in cities such as Jhansi, where troops looted and massacred the populace in retaliation for the stiff resistance the city offered the attacking force. It's a short book, which brings alive the times, the dangers, the smell of war and of death...a first-rate historical account of those turbulent times."

In the crowded video streaming platforms business, coming up with what is best is an uphill battle.
You need the right advice and technical know-how to choose the best. Most of the so-called popular streaming devices have so many ups and downs. Therefore, it would pay to carefully examine what you would want to spend your money on.
We all know that Netflix, HBO Max, Hulu, and other popular streaming platforms have dominated the market, and Netflix is the daddy to all. But this has not stopped other services from joining the ring.
We have the new kid on the block- Peacock TV, launched in July 2020. Peacock is owned by NBC and so far the service has gained at least 54 million signups.
Subscribing to all the streaming services would be next to impossible. We have narrowed our research to compare two excellent services -Peacock and Hulu.
Comparison can be based on three main factors, the streaming services price, their availability on devices and apps, and the shows and movies each has to offer.
Which streaming service is the best between Peacock or Hulu?
1. Hulu vs. Peacock Prices

Hulu originals, movies, and shows include The Great, Marvel’s Hit-Monkey. Dopesick, Nine Perfect Strangers, Drama, such as No Fue Mi Culpa, comedies such as Vacation Friends, etc
Peacock originals include The Amber Ruffin Show, Brave New World, Dr. Death, Rutherford Falls. Note that shows like The office can be watched for free.
It’s worth noting that Parks and Recreation will leave Hulu, and Peacock will own it exclusively.
Shows and movies availability comparison
Both streaming devices have equally the same shows. Both of them have ads with upgrades to an ad-free version for extra monthly free.
Both services allow you to watch network content a day after it aired
Hulu seems to be on top with the addition of FX on Hulu, and while both have profound originals, Hulu seems to outdo Peacock
3. Availability of Devices and Apps
Hulu apps and devices
To access Hulu, you can use apps such as NBC Sports, Fox News, Disney Now, CBS, ESPN, FOX Business, among others
There are many supported devices to watch Hulu from, such as Android phones and tablets, iPads, Apple TV, Android TV. Chromecast. Fire Tablets, PlayStation, Xbox, Mac, and PC browsers.
Peacock TV apps and devices
You can get Peacock on selected Smart TVs, Roku, Google Play Store, or even in gaming consoles. The streaming service can be compatible with the following apps; Android TV, Amazon Fire TV, Google Chromecast, Apple mobile devices, Comcast Xfinity Flex,
Apps and devices comparison
Hulu is accessible on most of the available streaming devices such as Amazon Fire Tv and Roku.
Meaning, when it comes to the availability of the services on apps and devices, Hulu wins the contest.
There has been no other streaming device with such, not even Netflix, which is the daddy to all streaming platforms.
With this, Peacock has its space, and the issue of free tier could mean more than one would think. This can doubtless be used as a determinant when choosing between Peacock and Hulu.
