Astronomers Introduce Black Hole Finder for Citizens to Find Newly-Formed Cosmic Gas Giants

Astronomers took a very interesting initiative and introduced an application, known as Black Hole Finder, which can help citizens spot newly-formed black holes.
The app was launched by the Dutch Black Hole Consortium in eight languages and is now available for citizens to use worldwide. Earlier, it was only available in Dutch and English, but now, the makers have added Spanish, German, Chinese, Bengali, Polish, and Italian which has widened the reach of this app.
Space enthusiasts across the world have been appealed to help scientists identify the sources which are interesting and should be followed up, which is known as potential kilonovas.

India Launches its 1st Reusable Hybrid Rocket 'RHUMI-1'

India launched its first reusable hybrid rocket 'RHUMI- 1', developed by the Tamil Nadu-based start-up Space Zone India with Martin Group, from Thiruvidandhai in Chennai.
The rocket, carrying 3 Cube Satellites and 50 PICO Satellites, was launched into a suborbital trajectory using a mobile launcher.
These satellites will be collecting data for research purposes on Global warming and Climate change. RHUMI Rocket is equipped with a generic-fuel-based hybrid motor and electrically triggered parachute deployer, RHUMI is 100% pyrotechnic-free and 0% TNT.

ISRO: Chandrayaan-4 Design Final, Samples from Moon by 2027

The designs of India's next mission to the Moon, Chandrayaan-4, which will bring rock and soil samples back to the Earth, was finalised, and will most likely happen in 2027, said ISRO chairman S. Somanath said on the occasion of National Space Day.
The Chandrayaan-4 spacecraft will have five separate modules, officials said. The Chandrayaan-3 spacecraft, which made a historic landing near the South Pole of the Moon, had three modules — the propulsion module (or the engine), a lander and a rover.

Chandrayaan-3 Reveals Stunning New Detail about Moon from Shiva Shakti Point

As India marked its first National Space Day on August 23, commemorating the historic landing of Chandrayaan-3 on the Moon's South Pole last year (2023), scientists unveiled a groundbreaking discovery from the mission's data.
A team led by Santosh Vadawale from the Physical Research Laboratory (PRL) in Ahmedabad revealed new insights into the lunar surface composition near the landing site.
The study showed that the lunar regolith around the landing site has a uniform elemental composition, primarily consisting of ferroan anorthosite rock, a product of the lunar magma ocean (LMO) crystallisation.
This discovery supports the lunar magma ocean (LMO) hypothesis, which suggests that the Moon's mantle formed as heavier materials sank inward while lighter rocks floated to the surface.
Interestingly, the chemical makeup of the regolith near the South Pole closely matches soil samples from equatorial and mid-latitude regions, further supporting the LMO theory. The presence of additional Mg-rich materials indicates a mixing of outer crustal material with deeper lunar layers.

UK Military Satellite Launches to Boost Space Power

The UK military launched its first ever dedicated Earth-imaging satellite.
Called Tyche, the washing machine-sized spacecraft has sufficient resolution to identify battlefield troop positions and vehicles.
It is a demonstrator that should be followed by a network of satellites this decade using a variety of sensors.
Some of these future spacecrafts will be able to see through cloud and even eavesdrop on radio transmissions.
Tyche's ride to orbit was booked on a SpaceX Falcon rocket flying out of California.

Centre Launches New AI-Based Surveillance System to Manage Pests

The Union Government launched the AI-based National Pest Surveillance System (NPSS) that will help farmers to connect with agriculture scientists and experts on controlling pests using their phone.
The aim of NPSS is to reduce the dependence of farmers on pesticide retailers and inculcate a scientific approach among them towards pest management. NPSS will analyse the latest data on pests using AI tools to help farmers and experts in pest control and management.

ISRO Successfully Places Earth Observation Satellite into Orbit

ISRO successfully placed an Earth observation and SR-O DEMOSAT satellites into intended orbit. The space agency launched its third and final developmental flight, Small Satellite Launch Vehicle-D3, carrying Earth Observation Satellite EOS-08.
The rocket lifted off majestically from the first launch pad at the Satish Dhawan Space Centre, situated about 135 km east of Chennai.
The objectives of the SSLV-D3-EOS-08 mission include designing and developing a microsatellite and creating payload instruments compatible with the microsatellite bus.
Built on the Microsat/IMS-1 bus, EOS-08 carries three payloads--Electro Optical Infrared Payload (EOIR), Global Navigation Satellite System-Reflectometry payload (GNSS-R) and SiC UV Dosimeter.
