The stepping stones of ISRO (Indian space research organisation) were laid by none other than our own beloved Dr. A.P.J. Abdul Kalam. After deploying its own GPS system through NAVIC, ISRO (India’s version of NASA) is all set to achieve another milestone in the field of space and technology. India is going to launch its own indigenous Reusable Launch Vehicle (RLV). According to indianexpress.com if this attempt becomes a success then the cost of access to space will decline significantly by 10 times.

What does RLV mean ?


RLV is a mechanism of launching which intends to bring down the cost of launch. Initially, a series of technology demonstrations will take place followed by the testing of HEX-01 (also called winged body). ISRO chairman Kiran Kumar explains the whole mechanism of this upcoming experiment. He further elucidates that HEX-01 will be launched from Sriharikota Island. After coming back from space it will be guided by satellites and radars to make it land in the Bay of Bengal. However, the final winged body will land on Sriharikota Islands only (i.e. on land only).

  • K Sivan, director of the Vikram Sarabhai Space Centre, Thiruvananthapuram said “These are just the first baby steps towards the big Hanuman leap. The final version will take at least 10-15 years to get ready since designing a human-rated reusable rocket is no kid stuff.
  • Apart from America, no other superpowers have attempted operational flights.
    • The US flew its space shuttle 135 times and then retired in 2011. It is said that it lost its capacity afterwards to send astronauts into space.
    • Russians made only a single space shuttle called ‘Buran’ which flew into space once in 1989.
    • French and Japanese made some experimental flights, though.
    • However, Chinese have never even attempted a space shuttle.
  • Indian space shuttle or RLV-TD began its construction nearly 5 years ago. Our government has invested nearly RS 95 Crores in this project. The capability of the vehicle to survive a re-entry at velocities more than that of a supersonic range will be tested by the flight. That is the reason this experiment has also been named as Hyper Sonic Experiment (HEX). Later RLV will be tested for another return flight experiment. After successful completion of these experiments, ISRO will plan the final configuration of the upcoming Reusable Launch Vehicle (RLV).
  • Scientists have even developed a material called ‘Indian space plane’. This will help in protecting the exterior surface of the shuttle from the friction caused heat while entering earth’s atmosphere (this temperature goes up to 5000-700 degrees Celsius). This thermal coating failure was the reason due to which the American space shuttle (Columbia) crashed which lead to the death of Kalpana Chawla in 2003. Hence, ISRO is emphasising on the thermal management.
  • Scientists have worked hard in making this dream come true. ISRO’s aim is to have its own ‘swadeshi space shuttle’. Sooner or later the RLV will be renamed as ‘Kalyanam’ after India’s famous former president Dr. A.P.J. Abdul Kalam (a legendary aeronautical engineer and rocket scientist) who dreamt of making India into a developed nation.

  • Given the vast potential which lies within our very own ISRO, we all hope this project becomes a success where all other superpowers have failed.
  • Even though the whole world is silent in attempting winged flights, ISRO’s main motto behind all this is bringing down the overall cost of building space infrastructures. This way scientists at ISRO believe that their capability will increase significantly.

Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.

Amitabh Bachchan is adored by the public for his unforgettable on-screen performances as well as his magnetic demeanour. Not only do fans love Amitabh Bachchan's outstanding performance, but the actor's heartwarming words are also highly regarded. A much moved Amitabh Bachchan, during his speech to the crowd of over 80,000 people at the Reliance Industries' annual event, said that the legacy left by Dhirubhai has had a positive impact on millions of people's lives worldwide.

When Bollywood superstar Amitabh Bachchan became bankrupt in the late 1990s, Dhirubhai Ambani stepped forward to give him financial assistance. In his speech, Bachchan remembered that Dhirubhai had sent Anil Ambani to offer him financial assistance during the crisis, which he had respectfully declined. Lenders began knocking on his door, losses mounted, and his bank account dwindled to nothing. He said, "Dhirubhai's money might have gotten me out of the problem quickly. However, I respectfully declined his offer and gradually began to find work again, which let me pay off my debt."

Irrespective of the age of your child, it is vital for parents to offer that extra support and assistance following an unsettling event.

In comparison to adults, children are prone to getting traumatized by troubling events easily, and this makes it important for parents to help their children when the times are tough. It could be a brutal accident, an unprecedented pandemic, a violent crime, or other disasters but with the right parental support, children have a higher chance of coming out stronger from an awful situation.

Anuja Kapur, Psychologist shares few tips wherein you can assist your child when tough times comes calling:

Every child responds differently to disturbing events:
What children feel about a current disaster in their life and how they react to it can come and go in waves. Children can act moody and withdrawn at times, struck with sorrow and fear at other times. There's no absolute "right" or "wrong" way to feel after a traumatic event so make sure not to dictate what your child or how your child should feel and react to the event.

European consumers will be able to use a single charger for all their portable electronics - an important step to increase convenience and reduce waste.

The European Commission, the executive arm of the European Union (EU), has announced plans for smartphone and other electronics manufacturers to fit a common USB-C charging port on their devices in an effort to reduce waste. In addition to phones, the rules will apply to other devices like tablets, headphones, portable speakers, videogame consoles, and cameras, reports The Verge. The decision will have a huge impact on Apple, as the company still uses its own Lightning connector to charge iPhones. The proposals only cover devices using wired, not wireless and a USB-C port is only mandatory for devices that charge using a cable.
