NISAR: ISRO and NASA Joint Mission Satellite to Track Climate Change, Disaster
NISAR Project: A major earth satellite is all ready to help people know more about climate change and help with disaster management. In a release, National Aeronautics and Space Administration (NASA) said that the satellite will be equipped with the largest reflector antenna, space agency has ever launched. The project called NISAR, a joint mission between NASA and the Indian Space Research Organisation (ISRO), has huge goals regarding studying climate change.
The SUV-size Earth satellite is expected to track subtle changes going on in the Earth's surface. The satellite will provide spot warning signs of volcanic eruptions along with monitoring groundwater supplies. It will also be tracking the melting rate of ice sheets and its impact on the sea level rise. The Earth satellite will also be observing shifts in the distribution of vegetation across countries. According to NASA, these kinds of changes have not been monitored for the entire globe and with NISAR, NASA is aiming to tap this field with the help of ISRO.

India likely to have Sky Eye GISAT-1 in Geostationary Orbit in April
The launch of India's first Geo Imaging Satellite (GISAT-1) to be placed in geostationary orbit will happen sometime during the first or second week of April, said K. Sivan, Secretary, Department of Space and Chairman, Indian Space Research Organisation (ISRO).
The GISAT-1 launch slated for March 28 got slightly delayed as some technical issues were observed in the satellite and the rocket. The issues observed issues have to be addressed even if they are minute ones. The GISAT-1 will be the country's first sky eye or earth observation satellite to be placed in geostationary orbit.
Originally the GISAT-1 was slated for launch on March 5, 2020 by Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10).

LG Electronics to Step Up Development of 6G Network Technology
LG Electronics has joined forces with two other partners to develop next-generation 6G network technology.
LG signed a partnership with Keysight Technologies, a US-based electronics test and measurement firm, and the Korea Advanced Institute of Science & Technology (KAIST), South Korea's leading research university.
Under the agreement, the three sides will cooperate in developing technologies related to terahertz, a key frequency band for 6G communications. They target to complete 6G research by 2024. LG said that the 6G network is expected to be commercialised in 2029.
LG established a 6G research centre with KAIST in 2019 and signed an agreement with the Korea Research Institute of Standards and Science last year to study 6G technologies.
Keysight Technologies is a major supplier of 6G terahertz test equipment. It has been providing equipment to LG and KAIST's 6G research centre.

Russia Launches 38 Foreign Satellites
Russia has successfully launched 38 foreign satellites for the 18 countries into orbit after the successful launch from Baikonur cosmodrome in Kazakhstan. Though, the launch was delayed due to the technical issues.
These satellites were successfully placed into orbit from the countries including Japan, South Korea, Saudi Arabia, Canada, Italy, Germany and Brazil. Among the 38 satellites, one was Challenge-1, which is the first satellite indigenously made in Tunisia. It was created by Telnet Telecommunications Group.
The launch of 38 satellites in one go by the Russia is of great significance in the light that, the Russian Space Sector is lagging behind ever since the fall of Soviet Union. It also lagged behind the international competitors because of several by corruption scandals and the technological stagnation. In the year 2018, Russia had launched a Soyuz rocket carrying the Russian cosmonaut and a NASA astronaut. But this mission was failed mid-flight and the crew had to carry out the emergency landing.

ISRO Demonstrates Technology for Quantum Encrypted Data Transmission
The Indian Space Research Organisation (ISRO) demonstrated quantum key sharing in free space over a distance of 300 metres for the first time in the country. The demonstration included a live video-conferencing with quantum key encrypted signals between two line-of-sight buildings at Space Application Centre in Ahmedabad.
This experiment can form the basis for a future quantum key encrypted data transmission between satellites and ground stations. A satellite-based quantum encrypted communication can be used to create a network for sharing secret messages.
Quantum cryptography "future proofs" any data transmission as the encryption cannot be cracked by existing computers. The current data security – for sensitive information such as banking – depends on large prime factorisation problems. A present day computer will be able to tell that the prime factors of 6 are 2 and 3 but it would not be able to do so for a number that is big enough.
Indian Astronaut Candidates for Gaganyaan Mission Complete Training
Four Indian officers, who were selected to become astronauts to crew Gaganyaan into orbit, have completed their one-year training course in Russia's Zvyozdny gorodok city near Moscow.
The Gaganyaan mission is aimed at sending astronauts to space in an orbital spacecraft.
The contract for the training of Indian officers was signed between the Indian Space Research Organisation (ISRO) and Russian launch service provider Glavcosmos in June 2019. The four pilots of the Indian Air Force (IAF) include a Group Captain and three Wing Commanders, according to the IAF sources.
