Intel Wins Second Phase of Contract to Help Pentagon Develop Chips

Intel Corp won a second-phase contract in a project aimed at helping the U.S. military make more advanced semiconductors within the United States.
Under the project, Intel will help the military develop prototypes of chips using its semiconductor packaging technology at factories in Arizona and Oregon. The packaging technology allows pieces of chips called "chiplets" from different providers to be combined into one package, helping cram more features into a smaller finished product while lowering its power consumption.
Intel`s work with the Defense Department comes as U.S. officials focus on boosting domestic semiconductor manufacturing in response to the rise of China as a strategic competitor. About 75% of the world`s chipmaking capacity is in Asia, with many of the most advanced plants in Taiwan and Korea, within the reach of the Chinese and North Korean militaries.
Intel is one of three companies in the world that can make highly advanced computer chips. The other two - Taiwan Semiconductor Manufacturing Co Ltd <2330.TW> and Samsung Electronics Co Ltd <005930.KS> - have packaging technology similar to Intel`s.

NASA Launches SS Kalpana Chawla Cargo Spacecraft

NASA launched a commercial spacecraft named after Indian Origin deceased NASA Astronaut "Kalpana Chawla". The spacecraft carried 4 tonnes of cargo including refined radishes for the International Space Station.
The spacecraft was built by a Virginia based company Northrop Grunman. It currently holds space station resupply contract with NASA. It is an aerospace and defence technology company. The company has named the space craft after Indian born astronaut Kalpana Chawla who died along with six other astronauts in 2003 Columbia Space Shuttle tragedy.
The spacecraft carried a new space toilet called the Universal Waste Management System. The 23 million USD commode is to be tested for future use in the International Space Station. It is 65% smaller and 40% lighter than the current toilet at the International Space Station. It also carried a radish-growing experiment to learn about survival and feasibility of growing plants in space.
The space craft has also carried cancer treatment technique requisites to test cancer drugs in micro gravity conditions.
Chawla was the first India-born woman to enter space. She also flew in 1997 as a primary robotic arm operator and also as a mission specialist. The Columbia spacecraft disintegrated during its return to earth that led to the death of the crew. The hot plasma entered the wing of the aircraft resulting in loss of control.
Chawla is regarded as the National Hero of India.
She was born in Haryana and moved to the US in 1982 to obtain a Master of Science degree in Aerospace Engineering.
The Government of Karnataka instituted Kalpana Chawla Award in 2004 to recognise young women scientists. An Eoan asteroid in the outer Asteroid belt of solar system has been named after Chawla.

China to Launch World's First Asteroid Mining Robot into Space in November 2020

A private company, Origin Space in Beijing (China) is set to send out the world's first asteroid mining robot into space in November 2020. The robot has been named 'asteroid mining robot' by the space start-up in China.
As per the report, the asteroid mining robot will be launched into space by a Chinese Long March series rocket. If the mission turns out to be a success, it may open a trillion-dollar industry.
While commenting on the development, the company added that being the first space-mining robot produced by a commercial company in the world, the mission will prove to be a milestone for the space resources industry.
Yu Tianhong, Origin Space Co-founder informed that the robot will not be engaging in any mining work but it will be testing the technologies. The goal will be to assess the asteroid mining robot's capabilities and to find out how well it can identify and extract the valuable resources vis-à-vis asteroid mining.

ISRO to Launch Venus Mission in 2025

The French Space Agency CNES announced that it is to participate in ISRO's Venus Mission, SHUKRAYAAN that is to be launched in 2025. The ISRO chairman and his French counter held talks to review the areas of cooperation between the countries.
VIRAL is Venus Infrared Atmospheric Gases Linker instrument that was co-developed with Russian Federal Space Agency Roscosmos and LATMOS atmospheres. After its Mars orbiter mission, Mangalyaan and moon mission Chandrayaan-1 and Chandrayaan-2, ISRO has now set its eyes on Venus.
France is one of the three countries with whom India collaborates in strategic sectors such as space, nuclear and defence. The two countries are US and Russia.
So far, 42 Venus missions have been sent to Venus from planet Earth. Japan's Akatsuki is currently flying around Venus.
In September 2020, a team of International Astronomers discovered the presence of phosphine gas in the atmosphere of Venus. The European space Agency Mission, Venus Express had earlier found signs of ozone in the upper atmosphere of Venus in 2011. These are considered as biomarkers, that is, possibility of presence of life forms in the planet.
The mission SHUKRAYAAN is to study atmospheric chemistry, compositional variations and dynamics of planet Venus. Earlier, the mission was scheduled to be launched in 2023.

Buried Lakes of Liquid Water Discovered on Mars

Three new underground lakes have been detected near the South Pole of Mars.
Scientists also confirmed the existence of a fourth lake - the presence of which was hinted at in 2018.
Liquid water is vital for biology, so the finding will be of interest to researchers studying the potential for life elsewhere in the Solar System.
But the lakes are also thought to be extremely salty, which could pose challenges to the survival of any microbial life forms.
Billions of years ago, water flowed in rivers and pooled in lakes on the Martian surface. But Mars has since lost much of its atmosphere, which means water canot stay liquid for long on the surface today.
However, it's a different matter underground.

United Arab Emirates to Launch Spacecraft to Moon in 2024

A top official in the United Arab Emirates said that his country plans to send an unmanned spacecraft to the moon in 2024.
Sheikh Mohammed bin Rashid Al Maktoum, who is also the ruler of Dubai, made the announcement.
Sheikh Mohammed's announcement comes after the launch of a Mars probe earlier this year by the UAE.
Sheikh Mohammed said the rover would be named "Rashid," the same name of his late father, Sheikh Rashid bin Saeed Al Maktoum.
If successful in 2024, the UAE could become the fourth nation on the Earth to land a spacecraft on the moon, after the US, the Soviet Union and China. India has tried and failed to land a spacecraft, as has Israel and Japan.

ASTROTAT Completes Five Successful Years of Maping Star

The ASTROSAT was the first multi-wavelength satellite launched by Indian Space Research Organization (ISRO). It was launched in September 2015. It has now completed five years of successful imaging of celestial objects.
The ASTROSAT explored stars, star clusters and mapped large and small galaxies of Milky Way galaxy called "Magellanic Clouds". The Magellanic Clouds are energetic phenomenon such as Gamma-ray bursts, supernovae, active galactic nuclei. In simple terms, they are called Satellite Galaxies of Milky Way.
The resolution of ASTROSAT is three times better than the resolution of NASA Mission, GALEX.
With the success of ASTROSAT, India has become one of the exclusive club of nations to have space-based observatories. The other countries that have space observatories are USA, Japan, European Space Agency, Russia and Japan. The satellite aims to provide high energy processes in binary star systems that contain black holes and neutron stars.
ASTROSAT was the first dedicated Indian Mission that studied celestial sources in X-ray, UV and optical spectral bands simultaneously with its five UV Telescopes and X-ray telescopes. The ground command and control centre of ASTROSAT is located in ISRO Telemetry Tracking and Command Network (ISTRAC), Bangalore.
The ground stations of ISTRAC are located in Bangalore, Hyderabad, Port Blair, Thiruvananthapuram, Sriharikota and Lucknow.
