When astronauts venture aboard the International Space Station, they see a world without borders. They work together as they orbit the Earth and there are no visible boundaries between them, even as members. Countries face geopolitics on the planet below.
This week, a SpaceX Crew Dragon spacecraft with a diverse crew lifted off from the Kennedy Space Center in Florida.
The capsule was carrying NASA astronauts Nicole Mann and Josh Cassada, Japan Aerospace Exploration Agency astronaut Koichi Wakata and Roscosmos cosmonaut Anna Kikina, the first Russian to travel on a SpaceX spaceflight.
“We live in the same world, we live in the same universe,” Cassada said. “Sometimes we experience it in a very different way than our neighbors. We can all keep that in mind… and keep doing amazing things. And do it together.
NASA’s SpaceX Crew-5 mission, now safe on the space stationis one of the first.
Nicole Aunapu Mann is the first native american woman to go into space as well as the first woman to serve as a mission commander for a SpaceX mission.
Mann grew up in Northern California and is a registered member of the Wailacki Tribe of the Round Valley Reservation. He has been a pilot and colonel in the United States Marine Corps. But it wasn’t until his mid-20s that he realized that he wanted to be an astronaut and that it was even possible.
“I realized that being an astronaut was not just something that was a possible dream, but something that is actually quite achievable,” Mann said. “I think as a child, I just didn’t realize that that was an opportunity and a possibility.”
A monstrous tsunami swept across the planet when a dinosaur-killing asteroid crashed into Earth 66 million years ago.
The impact caused the extinction of 75% of animal and plant life and created a chain of catastrophic events.
Waves more than a mile high moved away from the impact crater near Mexico’s Yucatan Peninsula and swept across the ocean floor thousands of miles away from the asteroid’s impact. The tsunami was thousands of times more energetic than those generated by earthquakes.
Sediment cores also showed that the tsunami powerful force even disturbed shorelines of New Zealand islands on the other side of the world.
We managed with a little help from our friends.
The James Webb Space Telescope recently teamed up with two other space observatories to produce stunning new images of the cosmos. By working together, these telescopes can provide a more complete picture of the universe.
The Chandra X-ray Observatory added X-ray data to some of Webb’s early images to reveal previously hidden aspects. X-rays identified exploded stars, a shock wave and superheated gas, all highlighted in bright pinks, purples and blues.
Furthermore, the astronomers combined Webb and Hubble data for show a pair of galaxies about 700 million light years distant from Earth. Webb scientists also spied a heavenly surprise, in the form of a distant galaxy, within the image.
Composting your product waste can be great for the environment, but There is an art to this environmentally friendly practice.
Food waste creates harmful greenhouse gases within a landfill, and little or none of it is composted. Composting means mixing food and yard waste with nitrogen, carbon, water and air to help the waste break down into rich soil your garden will love.
A compost pile that stinks doesn’t get enough oxygen and emits methane. To prevent the formation of this harmful gas and odor, turn your compost pile over every two to five weeks.

Swedish geneticist Svante Pääbo won the Nobel Prize for medicine this week for your pioneering use of ancient DNA to answer questions about human evolution.
In 2010, Pääbo sequenced the first Neanderthal genome and found that Homo sapiens interbred with them. Pääbo was also able to extract DNA from fossil fragments, which revealed the Denisovans, a new type of extinct human.
Their work has allowed researchers to compare human genetics with the DNA of Neanderthals and Denisovans.
Meanwhile, the Nobel Prize in chemistry was awarded to scientists who discovered how to join molecules, and the Nobel Prize in Physics went to quantum physicists for unlocking the strange behavior of particles.
Take a look at these new finds:
— Archaeologists have discovered the pieces of a almost 2000 year old classical statue depicting the mythical hero Hercules in northeastern Greece.
— The Pacific Ocean is shrinking and giving way to a new supercontinent, called Amasia, which will probably form in about 200 million to 300 million years.
– A New image from a telescope in Chile may resemble a cometbut it’s actually an incredibly long debris trail created when the DART spacecraft crashed into an asteroid last month.
