Kalamsat-V2- World’s Lightest Satellite

The Kalamsat V-2 is a communication satellite prototype which is world’s lightest satellite is built entirely by students and fresh graduates.

Kalamsat is a payload developed by students and Chennai based Space Kidz India for the first time. The Microsat-R satellite is meant for the Defence Research and Development Organisation (DRDO) purposes.The satellite has been named KalamSat after former Indian president Abdul Kalam, a pioneer for the country's aeronautical science ambitions.

The KalamSat satellite, lighter than a smartphone, the first-ever to be manufactured by 3D printing, was selected through a competition called “Cubes in Space”, jointly organised by NASA and “I Doodle Learning”. Cubes in Space is “the only global competition, offered at no cost, for students 11-18 years of age to design and propose experiments to launch into space or a near space environment on a NASA sounding rocket and zero-pressure scientific balloon”.

The weight of the probe, composed of 3D printed reinforced carbon fibre polymer, is sixty-four grams and it is fitted in a three and a half centimetres cube. The tiny probe, the first time an Indian student’s experiment was flown by NASA, was operated only for less than twelve minutes to demonstrate the performance of 3D printed carbon fibre in the micro-gravity environment of outer space and provide impetus to plan economical space missions in future.

This mission uses a modified version of the rocket's upper stage that allows it to serve as a long-term platform in orbit for experiments. A student-built payload called Kalamsat was incorporated into the upper stage for this launch.

The hosted Kalamsat v2 amateur communications payload was developed by Space Kidz. The payload is battery powered and was active for a few orbits to perform data transmission. It uses a modified new kind of electronic systems and buses which makes use of commercially off the shelf components to make the space exploration easier and economical. It was used for testing the performances of these newly modified systems like OBC, eps, communication, and structure. Power is provided by the PS4 stage's lithium ion batteries, which can operate for about 15 hours.The Kalamsat v2 payload itself was powered by its own solar cells.

The Kalamsat is the first to use the rocket`s fourth stage as an orbital platform. The fourth stage would be moved to higher circular orbit so as to establish an orbital platform for carrying out experiments, ISRO had said.

Pegasus Spyware: Flying Through The Air

Hundreds of millions of people can't imagine life without their smartphones. Almost every aspect of their daily lives, from the most mundane to the most intimate, is within easy reach and hearing distance of their smartphones. Only few people realize that their phones may be used as surveillance devices, with someone hundreds of miles away secretly extracting their messages, photographs, and location while also activating their microphone and recording them in real time. Such capabilities are present in Pegasus, a spyware produced by NSO Group, an Israeli maker of mass surveillance weapons. What is Pegasus? Pegasus is a hacking software – or spyware – that is developed, marketed and licensed to governments around the world by the Israeli company NSO Group. It has the capability to infect billions of phones using either iOS or Android operating systems. The spyware is named after Pegasus, the white winged horse from Greek mythology. It is named so because it "flies through the...

Unhackable Internet

W hy it matters? The internet is increasingly vulnerable to hacking; a quantum one would be unhackable. Quantum Computing A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a the quantum network have remained out of reach in large part because of the difficulty to send quantum signals across large distances without loss. Now, Harvard and MIT researchers have found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks. The U.S Department of Energy (DoE) explains how a quantum link will make it happen through two quantum phenomenon: the first is quantum entanglement, where two-particle ...

3D LASER SCANNING

What is 3D Scanning? 3D Laser Scanning is a non-contact, non-destructive technology that uses a line of laser light to digitally capture the shape of physical objects. 3D laser scanners generate "point clouds" of data from an object's surface. In other words, 3D laser scanning is a method of capturing the exact size and shape of a physical object into the computer world as a digital 3-dimensional representation. 3D laser scanners capture free-form shapes and measure fine details to quickly generate highly accurate point clouds. 3D laser scanning is ideal for the measurement and inspection of contoured surfaces and complex geometries that require massive amounts of data for accurate description and where using traditional measurement methods or a touch probe is impractical.process :3D Laser Scanning Data Acquisition. CLASSIFICATION 1. No Contact Scanning: Millions of points on the xyz coordinate system can be easily captured via non-contact scanning. This data prov...
