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.

The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.

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.

New Delhi, Jun 24: The Centre has made it mandatory for sellers to enter the 'Country of Origin' while registering all new products on government e-marketplace (GeM).

The e-marketplace is a special purpose vehicle (SPV) under the Ministry of Commerce and Industry which facilitates the entry of small local sellers in public procurement, while implementing 'Make in India' and MSE Purchase Preference Policies of the Centre.

Accordingly, the ministry said the move has been made to promote 'Make in India' and 'Atma Nirbhar Bharat'.

The provision has been enabled via the introduction of new features on GeM.

Besides the registration process, the new feature also reminds sellers who have already uploaded their products, to disclose their products' 'Country of Origin' details.

The ministry further said that failing to disclose the detail will lead to removal of the products from the e-marketplace.

"GeM has taken this significant step to promote 'Make in India' and 'Aatmanirbhar Bharat'," the ministry said in a statement.

"GeM has also enabled a provision for indication of the percentage of local content in products. With this new feature, now, the 'Country of Origin' as well as the local content percentage are visible in the marketplace for all items. More importantly, the 'Make in India' filter has now been enabled on the portal. Buyers can choose to buy only those products that meet the minimum 50 per cent local content criteria."

In case of bids, the ministry said that buyers can now reserve any bid for a "Class I Local suppliers. For those bids below Rs 200 crore, only Class I and Class II Local Suppliers are eligible to bid, with Class I supplier getting purchase preference".

In addition to this, the Department for Promotion of Industry and Internal Trade (DPIIT) has reportedly called for a meeting with all e-commerce companies such as Amazon and Flipkart to display the country of origin on the products sold on their platform, as well as the extent of value added in India.
