China Launches Its Most Powerful Rocket Yet

China launched Long March-5B, its largest carrier rocket, into orbit May 5, 2020.
The successful launch comes after two failed launches this year.
China has big plans for the moon and Mars; they'll be launching a Mars lander and rover in July and a lunar mission later this year.

Scientists Found a Seasonal Advancement in 220 Surge-Type Glaciers

Scientists from Wadia Institute of Himalayan Geology (WIHG), Dehradun have found a seasonal advancement in 220 surge-type glaciers in the Karakoram Range of Ladakh through a detailed assessment of some major surging glaciers of the Karakoram range using satellite images and thermal data.
The scientist carried out a detailed assessment of some major surging glaciers of the Karakoram range using multi-temporal and multi-sensor satellite images including Landsat 8 OLI, ASTER and Sentinel-2, Digital Elevation Models (DEM) and thermal data.

JNCASR Scientists Fabricate Energy-Efficient Photodetector for Security Application

Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute under the Department of Science and Technology, have fabricated an economical and energy-efficient wafer-scale photodetector (thin slice-based) using gold – silicon interface, for security applications.It could help detect weak scattered light as an indication of unwanted activity.
Photodetectors are the heart of any optoelectronic circuit that can detect light and are employed for a wide variety of applications ranging from controlling automatic lighting in supermarkets to detecting radiation from outer galaxy as well as security-related applications.
However, the material cost and the intricate fabrication processes involved in realizing high-performance detectors make them unaffordable for day to day applications.

Russia to Launch First Satellite to Monitor Arctic Climate

Russia will be launching its first Arktika-M satellite to monitor the Arctic climate and environment later this year. The information was shared by Vladimir Kolmykov, the General Director of the Lavochkin aerospace company.
The first Arktika-M spacecraft has been developed and is currently undergoing radio-electronic testing. The satellite is planned for launch towards the end of 2020. The second Arktika-M satellite is also under development and its launch is scheduled for 2023.

Indian-Origin Girl Vaneeza Names NASA's 1st Mars Helicopter

A 17-year old Indian-origin girl Vaneeza Rupani has named the 1st helicopter to be built for Mars as 'Ingenuity' (in Hindi it means the inventive character of a person). She received this credit when she submitted her essay in NASA's (National Aeronautics and Space Administration) 'Name the Rover' competition.
Before this new name, It was just named as "Mars Helicopter".
Along with Rupani , a total of 28, 000 students from each state and territory of the US (United States) participated in this competition.

NASA Names Companies to Develop Human Landers for Artemis Moon Missions

NASA has selected three U.S. companies to design and develop human landing systems (HLS) for the agency's Artemis program, one of which will land the first woman and next man on the surface of the Moon by 2024. NASA is on track for sustainable human exploration of the Moon for the first time in history.
The human landing system awards under the Next Space Technologies for Exploration Partnerships (NextSTEP-2) Appendix H Broad Agency Announcement (BAA) are firm-fixed price, milestone-based contracts. The total combined value for all awarded contracts is $967 million for the 10-month base period.

IIG Develops New Simulation Code To Study Electric Field Structure In Earths Magnetosphere

Scientists at the Indian Institute of Geomagnetism (IIG) an autonomous institution of the Department of Science and Technology (DST) developed a generalized one-dimensional fluid simulation code capable of studying a wide spectrum of coherent electric field structures in near-earth plasma environment or earth's magnetosphere.
The new simulation code can be useful in planning future space missions.
It can also lead to precisely controlled fusion laboratory experiments for ever-expanding energy needs of humanity.
