NASA astronauts Nicole Aunapu Mann and Josh Cassada, Japanese astronaut Kichi Wakata, and Russian cosmonaut Anna Kikina arrived at the International Space Station on Thursday. A SpaceX Falcon 9 rocket carried out the launch of the four-person Crew-5 mission. Read more in our weekly summary of space news.
Tsunami caused by meteorite that killed the dinosaurs :-
According to recent study, the asteroid that wiped off the dinosaurs may also have caused a tremendous tsunami that swept the ocean floor thousands of kilometres away from the Yucatan Peninsula, where the impact occurred.
Computer models were used in the study to mimic the Chicxulub impact and its effects. After simulating the impact, the researchers compared the results to the geological records of more than 100 locations worldwide and discovered evidence that corroborated the predictions made by the models regarding the tsunami’s strength and path.

“Pale yellow spots” should be sought for in searches for new Earths :-
It is improbable that Earth-like planets will have the close balance of land and water that we take for granted on our planet, according to a recent study. The study suggests that instead of looking for “pale blue dots,” which is how astronomer Carl Sagan described our planet, the search for new Earths should look for “pale yellow dots.”
According to the research, there is an 80% chance that terrestrial exoplanets are predominantly land-based planets, followed by a 19% chance that they are aquatic worlds. They discovered that there is a tiny 1% probability that such planets will have a balance between land and ocean similar to what is found on Earth.

Dimorphos develops a new tail :-
The asteroid Dimorphos acquired a massive tail of dust and debris following the impact by NASA’s DART (Double Asteroid Redirection Test) spacecraft, as can be seen from the image taken by the 4.1-meter Southern Astrophysical Research (SOAR) Telescope at the NOIRLab’s Cerro Tololo Inter-American Observatory in Chile.
Two days after the collision, scientists captured this image, which reveals a vast dust trail that is being forced in one direction by radiation pressure from the Sun, exactly like a comet’s tail is. This tail’s length is estimated by astronomers to be roughly 10,000 kilometres.

Launch and arrival at the ISS by NASA SpaceX :-
The SpaceX Crew Dragon spaceship named Endeavour carrying the four-person astronaut crew, which included the first Native American woman in space and a Russian cosmonaut, successfully docked with the International Space Station (ISS).
On October 7, around 2.30 AM IST, the capsule and orbiting space station converged. A SpaceX Falco 9 rocket from the Kennedy Space Center in Cape Canaveral, Florida, blasted Endeavour into orbit.
Chandrayaan’s spectrometer maps the quantity of sodium on the moon :-
For the first time, the Moon’s abundance of sodium has been mapped by Chandrayaan-2’s CLASS X-ray spectrometer. The X-ray Fluorescence Spectrometer (C1XS) on the orbiter identified sodium thanks to its distinctive X-ray line.
According to a study, a “thin veneer” of sodium atoms that are weakly attached to the lunar grains may be the source of some of the sodium signal. When compared to when they were a part of lunar minerals and crystals, these sodium atoms can be pushed out of the surface with more ease.
