Khushi Thapa, 18th July 2022:
Three people were killed after a gunman began firing in the food court of a mall near Indianapolis on Sunday, according to Greenwood Police Chief Jim Ison. The shooter was then shot and killed by a bystander.
The attack happened in the early evening at Greenwood Park Mall, according to the Indianapolis Star, and two other people were hurt.
“The real hero of the day is the citizen that was lawfully carrying a firearm in that food court and was able to stop the shooter almost as soon as he began,” Ison told reporters. He identified the armed bystander as a 22-year-old male.
According to the newspaper, the gunman was alone and had a firearm and numerous magazines of ammunition.
The names of the victims, the shooter, and the bystander were withheld by the police. At the sound of gunfire, shoppers and mall personnel fled or concealed themselves.
4 important Indian space exploration milestones in 2022
D V L S Pranathi, Mumbai Uncensored, 3rd January, 2023:
2022 was genuinely a historic one for space exploration. While we witnessed NASA successfully accomplish the Artemis 1 mission to return people to the Moon, we also saw the James Webb Space Telescope give us a treat to the eyes by showing insights into the previously unimaginable views of the cosmos.
Using its Launch Vehicle Mark III (LVM3) rocket, formerly known as the GSLV-MK3, the Indian Space Research Organization launched its first commercial satellite. It also accomplished the pretty underrated Small Satellite Launch Vehicle (SSLVfirst ) ’s flight. Still, it was a sting in the tail because the rocket accidentally injected three satellites into the wrong orbit due to a sensor malfunction, making the mission only a fragmentary success.
2022 was an incredible year for private space technology firms in India. India launched its first privately made satellite vehicle on the Prarambh mission, carried out by Hyderabad-based Skyroot Aerospace. Chennai-based Agnikul Cosmos successfully tested the Agnikul launch vehicle, which has the world’s first single-piece 3D-printed rocket engine. The four most significant events in Indian space exploration in 2022 are listed below.
ISRO SSLV’s Maiden Flight
The launch of the first SSLV satellite was a massive milestone for the organization. The satellite was made keeping the Allied market research in mind, which states that the global small satellite market will reach 13.7 billion dollars by 2023. With the rapid turnaround time necessary for commercial launches, it combines three solid fuel-based stages and a liquid fuel-based velocity-trimming module (VTM) to deploy the satellites in orbit. The vehicle could be integrated and tested in two days, according to ISRO Chairman S Somanath. After that, the launch using the vehicle could be accomplished within a week if rehearsal and launch were completed within the next two days.
The SSLV-D1 mission was successfully launched on August 8 of this year. However, after that, the mission control room was hushed since there had been a few data losses during the mission’s final stages. The satellites were later found to be in an elliptical orbit rather than a circular one leading to them being declared useless.
“SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. The issue is reasonably identified. Failure of logic to identify a sensor failure and go for a salvage action caused the deviation. A committee would analyze and recommend. With the implementation of the recommendations, ISRO will come back soon with SSLV-D2,” said a statement from ISRO at the time. (sourced from the Indian Express)
Despite all the setbacks, the mission still turned out to be a partial success as it helped ISRO test any new elements and technologies that were incorporated into the rocket, including the hardware and the entire architecture.
LVM3’s first commercial mission
This mission was an absolute skyrocket for ISRO in 2022, quite literally. It was ISRO’s heaviest rocket and successfully injected 36 broadband satellites for the UK-based satellite internet company OneWeb. Since it was the first commercial launch of such a Complex mission, it marked many firsts for ISRO.
Additionally, it was the first time that LVM3 carried several satellites and orbited them. It was also the most significant payload that ISRO has ever launched, at 5.8 tons. On October 23, LVM3 launched after midnight from the second Launchpad of the Sriharikota spaceport, successfully putting 16 satellites into orbit and making sure they wouldn’t collide. Before that, Chandrayaan 2 was launched, and two development flights with LVM3 were successful.
The significance of LVM3’s string of successful launches extends beyond simply establishing India as a competitive competitor in the commercial satellite launch market. The Gaganyaan mission will send Indian astronauts into space, and ISRO is now working to human-rate the launch vehicle. India will become the fourth nation to launch crewed spacecraft thanks to the Gaganyaan mission, following the United States, Russia, and China.
Launch of Vikram S
Vikram S rocket was Skyroot Aerospace’s first private rocket launch in the country. It was launched from the Launchpad at Sriharikota at 11:30 am on November 18. It was a sub-orbital launch with the spacecraft traveling slower than the orbital velocity. This indicates that the spacecraft reached outer space but did not remain in orbit around the earth lasting lesser than five minutes. This series of rockets has been named after Vikram Sarabhai, the founder of the Indian Space program.
The engine launch pays homage to another great Indian scientist, APJ Abdul Kalam, and is named “Kalam-80”. The core structure of the satellite was made using carbon composites, and the thrusters used for spin stability were 3-D printed. Vikram S’s launch opened the door for Indian private space enterprises to take over some of the historical work done by ISRO, such as satellite launches.
First 3D-printed single-piece rocket engine:
Even though Skyroot is a groundbreaking Indian Tech startup, Agnikul, a Chennai- based startup, managed to overpower it by successfully test-firing Agnilet. This was its 3-D printed rocket engine at Thiruvananthapuram’s Vikram Sarabhai Space Centre. It is the world’s first single-piece 3-D printed rocket engine. It is intended to launch payloads up to 300 kg into low-Earth orbit along with the company’s proposed small satellite launch vehicle, Agnibaan, which is now in development. Agnilet is a “semi-cryogenic” rocket engine powered by a mixture of liquid kerosene at room temperature and super cold liquid oxygen.
At the Satish Dhawan Space Centre in Sriharikota, the startup also inaugurated India’s first private Launchpad and mission control center in November. The Launchpad is four kilometers from the mission control center and is built to allow and assist liquid-stage controlled launches. Shortly, Agnikul intends to use this facility to launch the Agnibaan rocket.
India has once again succeeded in spellbinding the globe with its impressive technology and all the geniuses who sacrificed their time and energy and put in every drop of their sweat and blood to accomplish each of these milestones.
Why Italian Prime Minister Mario Draghi has suddenly decided to resign?
Tista Karmakar, Mumbai Uncensored, 16th July 2022:
The Italian Prime Minister Mario Draghi has announced that he will resign from his position after the Five Star Movement (M5S) on Thursday July 14 hinting at a political crisis paving its way for early elections.
To his statement Mr. Draghi said, “The pact of trust underlying the government has failed. In recent days there has been the utmost commitment on my part to continue on the common path, also trying to meet the needs that have been advanced to me by the political forces. As is evident from today’s debate and vote in parliament, this effort was not enough. From my inauguration speech I have always said that this executive would only go forward if there was a clear prospect of being able to carry out the government programme on which the political forces had voted their confidence. This compactness was fundamental to face the challenges of these months. These conditions no longer exist.”
In 2021 a surge of political change happened in response to the previous year’s COVID-19 pandemic crisis. The whole nation went through a state of emergency forced by the government of Guiseppe Conte, supported by the M5S, the Democratic Party (PD), a small left party, and Italia Viva. However, after the pandemic hit Italy, Matteo Renzi’s Italia Viva distanced itself from the government in December 2020 leading to its fall in February, 2021.
The former governor of the European Central Bank Mario Draghi led the establishment of a national unity government and was widely supported by all major party members except a post-fascist and a small left party.
The former European Central Bank chief Draghi has met the president, Sergio Mattarella over the issue of his resignation. However, Mr. Mattarella rejected Draghi’s resignation on Thursday night and at the same time advised him to address the parliament in order to get the support he needed.
Mr. Draghi has announced his resignation on Thursday after the populist coalition ally the M5S refused to support a key bill of the government. Reportedly the Draghi government formed in allyship of this populist, the left, the right, and the central parties in February 2021 right after Italy stumbled into the corona virus crisis.
Draghi and his government won a confidence vote of 172-39 to pass the bill in the Senate despite the M5S’s refusal. The bill provides support of 26 billion euros to the consumer and industries struggling with the energy crisis. The bill also included a provision for allowing the construction of a huge incinerator for Rome’s rubbish management project which was highly opposed by the M5S.
Mr. Draghi addressed the issue of the populist M5S’s disinterest in the bill by saying, “The majority of national unity that has sustained this government from its creation doesn’t exist any more.” To which the president advised Mr. Draghi to reach parliament in order to get the solid support he needs the most.
However, if Mr. Draghi fails to gain support from the parliament to carry out his economic reform, president Mattarella can call for an early election in late September since the current parliament’s term expires on 2023.
The M5S has lost its significance in the recent local elections and strolled in opinion polls. The populist party has also cleared their stance by being in opposition to the economic reform bill. A pro-Europe party leader said criticizing the M5S’s opposition, “is not like picking up a menu and deciding, antipasto, no, gelato, yes.” Whereas the Draghi government has been efficiently performing throughout the pandemic via the virtual medium. So, the Draghi government has become a pivotal figure in Europe amid the Russia-Ukraine war and the economic crisis. Some politicians say that Draghi’s decision to resign or not is important following the unfortunate departure of British Prime Minister Boris Johnson. The whole of Europe will be looking after Italy in the coming weeks.
Comet K2 forced scientists to scratch their heads
Tanvi Kapila, Mumbai Uncensored, 16th July 2022:
An enormous comet nicknamed as K2 is twice the size of Mount Everest. Another aspect to be observed is that the comet has entered in the Solar system and was all set to fly by earth this week.
The most distant active comet, Comet K2, has intrigued scientists.
The first time this mega comet was discovered and came to notice was in 2017 by the Panoramic Survey Telescope and Rapid Response System(PanSTARRS), which also explains the comet’s full name Comet C.2017 K2 (PanSTARRS). The comet, however, at the time of discovery, was 2.4 Billion km away from the sun which is approximately 16 times farther than the distance between Earth and Sun. Scientists were shocked to discover that K2 already had a gaseous coma because comets, which are primarily composed of water ice, are typically thought to be as motionless and lifeless as rocks at this point in the solar system.
The official time for the Comet K2’s approach was 11:09 P.M. on 14 July 2022 EDT on Thursday (8:39 A.M. IST, Friday). Moreover, the fascinating fact about this gigantic comet is that its nucleus is estimated to be around 11 miles (18 kilometers) across – roughly ten times larger than most comets according to the Hubble Space Telescope. Additionally, the halo (atmosphere) or coma has a diameter of around 81,000 miles (130,000 kilometers). It traveled 270 million kilometers (168 million miles) away from Earth (beyond the orbit of Mars). Many were able to catch glimpse of the comet through their telescopes and the pictures surfaced across the internet.
The next sight of the comet is predicted in December 2022 approaching closest to the sun and will grow brighter.
However, debates are ongoing about the right size of the comet between scientists and will continue to be so.
