Isro to Launch IIT-Bombay Students' Satellite 'Pratham' on Monday

September 25, 2016

Sep 25: Indian space agency Isro will shoot off the "Pratham" satellite designed and built by students of the IIT-Bombay among the eight satellites including its weather satellite on Monday, an official said in Mumbai.

Conceptualised in 2008 with the aim of making IIT-B a centre for space science and technology research, the satellite weighs just 10kg, is designed to fit within a cube of 30cm, and has a life span of around four months.

"The objective of Pratham is to empower the students involved with the skill set required to develop a statellite through various stages of design, analysis, fabrication and testing," said the official.

The project will also kickstart a collaboration between IIT-B and other Indian universities keen to contribute in the space sector and to share knowledge and facilties.

This has led to completion of ground-stations for tracking the satellite in several college, including the Atharva College of Engineering here.

The IIT-B has collaborated with some international universities like UCL, London and IPGP, Paris for the project.

Pratham will transmit data when it passes over India and any university with a small ground station can detect its signals and measure the total electron counts (TEC) above the ground station as part of the education process to spread awareness among the students.

The student-designed satellite's mission is four-fold: acquiring knowledge in the field of satellite and space technology, to fully design it by the students of IIT-B, launch it and measure TEC of uonosphere above India and Paris, and involve students from other universities in the satellite project, said the official.

Pratham's payload instrument comprises two monopole antennae transmitting at 145.98MHz and 437.45MHz.

Measuring 30.5cm by 33.4cm by 46.6 cm, it weighs 10.12kg, is made of aluminium alloy and other space-grade materials, and has an on board computer.

It has three monopoles, GPS, magnetometer, sun sensors, magnetorquers and is powered by Li-ion battery and four solar panels.

It will be positioned in a sun-synchronous orbit around 670 km away and will pass over India around 11.30am.

For the project, entirely funded by the IIT-B, the Isro has provided lot of technical help in terms of testing and guidance and the integration of the flight model of Pratham for which tests have been carried out in ISAC, Bangalore and SHAR, Sriharikota.

Each year in September, a rigorous selection test was conducted for all IIT-B students from which they were inducted into the Pratham team and formalized after ascertaining their satisfactory work.

The current strength of the team which has completed the project after more than eight years is around 30, the official said.

New Delhi, Aug 2: The National Commission for Women (NCW) has issued notice to some Bollywood celebrities named in a complaint against the promoter of a company for allegedly blackmailing and sexually assaulting a number of girls on the pretext of giving them a career in modelling.

Taking cognizance of the complaint filed by social activist Yogita Bhayana of People Against Rape in India (PARI), the NCW scheduled a virtual hearing presided by its chairperson on August 6.

The complaint against Sunny Verma, promoter of a company named IMG Ventures with its headquarter in Chandigarh, alleged that he has been blackmailing and sexually assaulting a number of girls on the pretext of giving them career in modelling.

PARI's Yogita Bhayana wrote a complaint letter to NCW chairperson Rekha Sharma.

"Through his company, he (Sunny Verma) invites the girls on the pretext of organising a Miss Asia contest with a claim that the contest will launch them as models. To make it look genuine, his company has also been taking an entry fee of Rs 2,950. Once the girls apply, they are alluded by the female accomplices of Sunny Verma to submit their nude pictures in order to get the better ranking in the contest," the complaint letter said on July 31.

It alleged that Verma, after receiving the pictures and sometimes even before, used to get in touch with the girls and ask for completely nude pictures and videos.

The complaint letter said that Verma also used to allude as well as threaten the girls to submit to his sexual desires if they were interested in modelling as a career or wish to win the contest.

"Once he established a physical relationship with the girls, he used to blackmail them for regular sexual favours. Many girls from across the country have suffered a sexual and mental assault from Sunny and his accomplices," said the complaint citing several letters, texts and audio clips from several girls as proof of this modus operandi of Sunny Verma and his company.

The complaint also said that Sunny Verma has been previously also arrested on charges of sexual assault.

"We would demand that NCW should investigate the case to its depth and get the guilty punished so that any other person should not dare to exploit these kinds of innocent girls on any pretext. It will be a message to people like Sunny Verma and all associated Bollywood stars. Looking forward to strict action from NCW against sexual offenders like Sunny Verma & others," the complaint said.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

Cybersecurity researchers on Monday warned of a Trojan malware campaign which is targeting India's co-operative banks using COVID-19 as a bait.

Seqrite, the enterprise arm of IT security firm Quick Heal Technologies, detected the new wave of Adwind Java Remote Access Trojan (RAT) campaign.

Researchers at Seqrite warned that if attackers are successful, they can take over the victim's device to steal sensitive data like SWIFT logins and customer details and move laterally to launch large scale cyberattacks and financial frauds.

According to the researchers, the Java RAT campaign starts with a spear-phishing email which claims to have originated from either the Reserve Bank of India or a nationalised bank.

The content of the email refers to COVID-19 guidelines or a financial transaction, with detailed information in an attachment, which is a zip file containing a JAR based malware.

Upon further investigation, researchers at Seqrite found that the JAR based malware is a Remote Access Trojan that can run on any machine which has Java runtime enabled and hence it can impact a variety of endpoints, irrespective of their base operating system.

Once the RAT is installed, the attacker can take over the victim's device, send commands from a remote machine, and spread laterally in the network.

In addition, this malware can also log keystrokes, capture screenshots, download additional payloads, and extract sensitive user information, Seqrite said, adding that such attack campaigns can effectively jeopardise the privacy and security of sensitive data at the co-operative banks and result in large scale attacks and financial frauds.

To prevent such attacks, users need to exercise ample caution and avoid opening attachments and clicking on web links in unsolicited emails.

Banks should also keep their operating systems updated and have a full-fledged security solution installed on all the devices, Seqrite advised.
