Scientists Confirm Existence of a Fifth Layer in Earth's Core

The Earth is composed of four layers - the crust, the mantle, the outer core and the inner core - each with unique characteristics and properties. A new study has now confirmed the existence of a fifth layer, called the innermost inner core.
The fifth layer is made of iron and nickel, the same materials that comprise the rest of the inner core.
The team of researchers from the Australian National University measured the speeds at which these seismic waves penetrate and pass through the Earth's inner core. The team believes that this has presented evidence of a distinct layer inside Earth known as the innermost inner core.

SpaceX Launches Four Astronauts from US, Russia, and UAE to Space Station

SpaceX launched four astronauts to the International Space Station for NASA, including the first person from the Arab world (United Arab Emirates) going up for an extended month long stay.
The Falcon rocket bolted from Kennedy Space Centre.
The first attempt to launch them was called off at the last minute because of a clogged filter in the engine ignition system.
They will replace a U.S.-Russian-Japanese crew that has been up there since October 2022. The other station residents are two Russians and an American whose six-month stay was doubled.

Scientists Discover New Layer at Earth's Inner Core

According to seismologists from The Australian National University (ANU), data gathered from seismic waves caused by earthquakes has shed new light on the deepest parts of the Earth's inner core.
A team of researchers found evidence of a new layer to the planet sitting within the inner core.
The researchers believe they have documented evidence of a distinct layer inside Earth known as the "innermost inner core", a solid "metallic ball" that sits within the centre of the inner core, by measuring the different speeds at which these waves penetrate and pass through the Earth's inner core.
Earlier, it was thought the Earth's structure comprised four distinct layers -- the crust, the mantle, the outer core and the inner core, but the current findings confirm there is a fifth layer.

Kerala Becomes First State to Use Robotic Scavengers to Clean Manholes

The Kerala government launched robotic scavenger, Bandicoot, to clean sewages in this temple town, becoming the first state in the country to use robotic technology to clean all its commissioned manholes.
Water Resources Minister, Roshi Augustine, launched Bandicoot under the Guruvayur Sewerage Project in Thrissur district by the Kerala Water Authority (KWA), as part of the 100-day action plan of the state government.
Bandicoot, developed by Kerala-based Genrobotics, bagged 'Kerala Pride' award at the Huddle Global 2022 conclave organised by Kerala Start-up Mission (KSUM).

Russia Launches Spacecraft to Rescue Astronauts Stuck on ISS

Russia launched a rescue ship for two cosmonauts and a NASA astronaut whose original ride home sprang a dangerous leak while parked at the International Space Station.
The Russian Space Agency delayed the launch of the replacement Soyuz, looking for any manufacturing defects. No issues were found, and the agency proceeded with predawn launch from Kazakhstan of the capsule with bundles of supplies strapped into the three seats.
The three men launched in this Soyuz last September on what should have been a six-month mission. They'll now stay in space for a full year, until a new capsule is ready for their crew replacements for liftoff in September. It was their Soyuz that just launched with no one on board.
