India Approves $318 Million Project for LIGO Gravitational Field Observatory
The Union Cabinet has approved a gravitational-wave detector project in Maharashtra costing Rs 2,600 crore, estimated to be built by 2030. Union minister Jitendra Singh stated that a 174-acre land has been acquired in Hingoli district for its development.
LIGO-India, the third observatory of its kind, will be built to match the specifications of the LIGO observatories in the US, and will work alongside them. Currently, the project is being collaboratively worked upon by a consortium of Indian research institutions and U.S. observatories along with various international partners.
The first two LIGO observatories are located in Louisiana & Washington state, US
The Indian government granted provisional approval for the project in February 2016. The proponents have now identified and assessed a suitable, stable site for the detector, and are now in the planning phase for the observatory.
The L-shaped LIGO instrument boasts two arms, each measuring 4 km long. Laser pulses are fired simultaneously through both arms, bouncing off the mirrors at the ends to return to the vertex. A detector analyzes whether the pulses coincide upon return. Detecting gravitational waves involves recording and analyzing the slightly out of time pulses in the detector produced by their passage.
In extreme environments, like when black holes collide, very massive objects emit gravitational waves. They provide a way to examine the gravitational characteristics of the source, similar to how light can be used to examine its electromagnetic features.
Concept of Operation of the interferometric gravitational wave observations
Two LIGOs can detect gravitational waves, but a third observatory is needed for better 'triangulation'. Four observatories are even better. Italy and Japan are upgrading detectors with this setup in mind to enhance gravitational wave detection.
The Department of Atomic Energy and the Department of Science and Technology are building LIGO-India in partnership with the U.S. National Science Foundation (NSF) and various national and international research institutions. The United States will supply critical lab components valued at approximately Rs 560 crore ($80 million).
Dr. Souradeep announced that the LIGO-India Observatory will contribute to anticipated astronomical and astrophysical gains from the global LIGO network.
Airbus showed the project of the space station LOOP. The service life of the ISS is coming to an end and it is already necessary to create a replacement for it. Against the backdrop of what is happening in the world, humanity will either be able to create a new version of the space station accessible to all, or will build its own stations in near-Earth orbit. Airbus unveiled the concept of the new space station LOOP. The new project is a universal three-story station for life and work in space. The station can be delivered into orbit in a single launch of SpaceX's super-heavy launch vehicle. Each floor is 8 meters in diameter and can be converted into living quarters, laboratories and docking stations. The decks are connected at the center of the structure by a so-called "tunnel", which is surrounded by greenhouse modules. The LOOP station is designed for a crew of four, but can be adapted to accommodate up to eight people.
Elon Musk's Tesla Bot robots have learned to walk slowly. Tesla reported to shareholders on how the development of the universal android Tesla Optimus is progressing, which should become an assistant to a person in everyday life and at work. Also, the engineers of the Elon Musk Corporation taught the Optimus robots to collect things. In the video, anthropomorphic machines shift small items and arrange them in containers. According to Tesla experts, the learning of machines is based on the repetition of certain actions for a person. It is assumed that by the time of release, the Tesla Optimus robot will cost no more than $100,000. In the long term, Tesla Bot robots will bring the company the main income, according to Elon Musk, the demand for them will be up to 10 billion units.
Spherical building-screen "Sphere" opened in Las Vegas. The world's largest futuristic building in the form of a sphere covered with LED panels is open in Las Vegas. The screen of the unusual building "MSG Sphere" is made of 1.2 million LED panels, the display area is 54,000 sq.m. it is now the largest LED display in the world. There is also a spherical screen inside the building of the sphere, its resolution is 19,000 by 13,500 pixels, 164,000 speakers are installed inside the hemisphere. Thanks to such a large number of LEDs, at night the building is very brightly lit from the outside, and it can be seen even during the day for several kilometers. The MSG Sphere building has a capacity of 17,600 seats or 20,000 standing places and will host major concerts and sporting events. MSG Sphere will officially open on September 29th. The project of an unusual building cost 2.3 billion dollars, and is now considered the most expensive entertainment venue in Las Vegas.
A robot dog with a flamethrower, Thermonator, was presented by the American company Throwflame. The robot is based on the four-legged robot Unitree Go1 from the Chinese company Unitree. The robot can be controlled using a wireless controller and has autonomous functions. The robot has an artificial intelligence system to navigate or detect people. On the back of Thermonator there is a modular ARC flamethrower with an electric drive, powered by gasoline or a mixture of gasoline and diesel fuel, which allows the robot to throw a stream of flame approximately 10 meters within 30 seconds. When equipped with the most powerful battery available to the robot, it will operate for up to 45 minutes. The cost of the Thermonator robot has not yet been announced. The manufacturer does not specify for what purposes the robot can be used.
Russian satellite Internet, Bureau-1440 company. The Russian analogue of satellite Internet Starlink has been successfully tested. The Bureau 1440 company, part of ICS Holding, announced the successful testing of the Russian satellite Internet; the connection was made to three Rassvet-1 type satellites launched earlier by a launch vehicle from the Vostochny cosmodrome. During the tests, data was transmitted at a speed of about 12 Mbit/s, and the delay was 41 ms, in the future the speed is expected to be 100 Mbit/s or more. After the completion of the necessary experiments, all Rassvet-1 satellites will be deorbited, after which Bureau 1440 will begin to prepare for mass production similar devices. From 2025, it is planned to launch 10-12 rockets into orbit per year, about 15 satellites are placed in one rocket. It is planned that the Russian satellite Internet service will begin its work in 2027, and by 2035 the constellation of satellites will reach 900 devices , which will ensure Internet coverage throughout the country.
