Physicists build an 'Anti-laser' to Charge Your Phone

Scientists have figured out a way to perfectly beam energy across any room, thanks to a sci-fi like device they call an "anti-laser."
The idea is simple: Just like a laser emits light particles, or photons, one after another in a neat and orderly row, an anti-laser sucks up photons one after another in reverse order. Researchers have long speculated that a device like this might make wires and charging cables a thing of the past, allowing people to beam energy invisibly across a room to a laptop or phone and power it without plugging it in.
But though basic anti-lasers have been tested before, the real world is not as neat and orderly as a laser pointed at a fixed receiver in a laboratory. Electronics move around, objects get in the way, walls reflect energy in unexpected ways. The new anti-laser demonstrated in this experiment accounts for all that, and it receives scattered energy beamed around a space in an unpredictable pattern — still receiving 99.996% of the sent power.

Larsen and Toubro Delivers a Booster Segment to ISRO

Larsen and Toubro delivered a Booster segment, the first hardware for the Gaganyaan Mission to ISRO. The company has delivered the module ahead of schedule.
Booster segment is an engine or can also be a booster rocket. It is either the first stage of a multi stage rocket or a shorter burning rocket used to augment the take off thrust of the space vehicle. In simple words, the booster segments solve the following two purposes:
In Low Earth Orbit rockets, booster segments are used to launch a space craft.
Booster segments act as thrust providers when the mission is beyond low earth orbit.
Here the Gaganyaan Mission aims to send astronauts to Low Earth Orbit (400 km) and so here the booster segment is used to launch a space craft.

Param Siddhi Bags 63rd Rank in List of most Powerful Supercomputers in World

The Department of Science and Technology (DST) said that Param Siddhi, the supercomputer established under the National Supercomputing Mission (NSM), has achieved 63rd rank in the list of 500 most powerful supercomputers in the world.
The supercomputer with Rpeak of 5.267 Petaflops and 4.6 Petaflops Rmax (Sustained) was conceived by C-DAC and developed jointly with support of DST and the Ministry of Electronics and Information Technology (MeitY) under the NSM.

Dragon Capsule Docks with Space Station

The four astronauts who left Earth arrived at the International Space Station (ISS).
Their SpaceX Dragon capsule made a series of inch-perfect manoeuvres to bring them into an attachment position on the front of the orbiting lab.
Commander Mike Hopkins, Shannon Walker, Victor Glover and Soichi Noguchi will be spending the next six months aloft.
They join three individuals already aboard - Kate Rubins, Sergey Ryzhikov and Sergey Kud-Sverchkov.
Raising the resident complement to seven individuals will triple the amount of microgravity science that can be conducted on the 410 km-high outpost.

Nasa SpaceX Launch

Four astronauts - three from the US and one from Japan - have launched from Florida on a mission to the International Space Station (ISS).
The crew rode to orbit in a rocket and capsule provided by the SpaceX company.
It's only the second time the firm has supplied the service.
The US space agency Nasa has said it is now entering a new era in which routine astronaut journeys to low-Earth orbit are being conducted by commercial providers.
The four individuals making their way up to the ISS are the Americans Michael Hopkins, Victor Glover and Shannon Walker, and the highly experienced Japanese space agency (Jaxa) astronaut Soichi Noguchi.

NASA Gets Ready to Bring Rock Samples from this Planet to Earth

In a historical development, world's premier space agency National Aeronautics and Space Administration (NASA) is going to attempt to bring Mars rock samples back to Earth. The samples will be brought back to Earth in order to help NASA scientists to study about the surface of the Red Planet.
An independent review report was released by US-based NASA hinting the agency is all set to undertake its Mars Sample Return (MSR) campaign to bring rock samples from the Red Planet.
The agency established the MSR Independent Review Board (IRB) to evaluate its early concepts for a groundbreaking, international partnership with ESA (European Space Agency) to return the first samples from another planet.
After a thorough review of the agency's planning over the past several years, the IRB unanimously believes that NASA is now ready to carry out the MSR program, the next step for robotic exploration of Mars.

SpaceX Launch of Crew on First Operational Mission Delayed

NASA and high-tech entrepreneur Elon Musk's rocket company SpaceX announced a 24-hour weather delay of their planned launch of four astronauts into orbit for NASA's first full-fledged human mission using a privately owned spacecraft.
The liftoff time slipped due to forecasts of gusty, onshore winds over Florida -- remnants of Tropical Storm Eta -- that would have made a return landing for the Falcon 9 rocket's reusable booster stage difficult.
SpaceX's newly designed Crew Dragon capsule, dubbed "Resilience" by its crew, was rescheduled for launch atop the Falcon 9 from NASA's Kennedy Space Center in Cape Canaveral.
The crew for the flight to the International Space Station includes three American astronauts -- Victor Glover, Shannon Walker and the mission commander, Mike Hopkins, a U.S. Air Force colonel who is to be sworn into the fledgling U.S. Space Force once aboard the orbiting laboratory.
The fourth crew member is Japanese astronaut Soichi Noguchi, making his third trip to orbit after flying on the US space shuttle in 2005 and a Russian Soyuz spacecraft in 2009.
