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.
