New study: Dinosaurs already became extinct before the asteroid hit Earth | abroad – Commentary Box Sports

The study shows that dinosaurs were already in persecution 10 million years before the asteroid impact on what is now Mexcio. The researchers analyzed 1,600 fossils from 247 different types of dinosaurs. In the end, one can calculate the rates of diversity and extinction for six families of dinosaurs.

“We looked at the six largest families of the entire epoch, which spanned from 150 to 66 million years ago. We saw that all six did really well,” said Fabien Condamine of the Evolutionary Sciences Institute in Montpellier. “But 76 million years ago it was There is a reversal: more species have gone extinct and in some cases new species no longer appear.”

cooler climate

The researchers used computer models to arrive at the most likely outcomes. “In the analyses, we examined several reasons for the decline of the dinosaurs,” said Mike Benton, co-author of the study. “Obviously there were two big factors. First, the climate became significantly cooler, which made life more difficult for dinosaurs because they were used to heating. A quiet decline in herbivores followed, making ecosystems more turbulent and affecting other dinosaur species.” The longest-lived species were the most vulnerable to extinction, probably because they weren’t able to adapt to the new conditions.”

The CST-100 Starliner capsule has passed its flight readiness review (FRR) for the upcoming liftoff, which will kick off the uncrewed Orbital Flight Test 2 (OFT-2) mission to the station, NASA and Boeing representatives announced today (July 22). Read the full story here.

Over the weekend, engineers mated the Starliner spacecraft to its Atlas V rocket, marking a key milestone ahead of the mission’s launch next week. See the photos here.

NASA hands SpaceX contract for first mission to Jupiter's moon Europa – Fox Business

Published

NASA’s (National Aeronautics and Space Administration) Southern California-based Jet Propulsion Laboratory (JPL)  has awarded SpaceX (Space Exploration Technologies Corp.) with the launch services contract for the Earth’s first mission to conduct detailed investigations of Europa. 

The “Europa Clipper” mission is set for October 2024 and NASA said in a Friday release that the spacecraft will launch on a Falcon Heavy rocket from NASA’s Kennedy Space Center in Florida.

The contract award is approximately $178 million dollars

Scientists at the agency will explore whether Jupiter’s icy moon, which is about 90% the size of Earth’s moon, could host conditions suitable for life. 

The world – discovered first by famed astronomer Galileo Galilei – shows strong evidence for an ocean of salty water beneath the planet’s crust, thought to contain twice as much water as Earth’s oceans combined.

NASA believes that the moon’s ice shell is around 10 to 15 miles thick and its internal ocean is estimated to be around 40 to 100 miles deep.

The mission will send Europa Clipper to orbit around Jupiter to perform close flybys of Europa on an elliptical path. The orbiter’s suite of science instruments will help to measure the ocean’s depth and salinity and the thickness of its icy shell, map surface geology and composition, search for plumes of water vapor that could be emitted from Europa’s crust and subsurface lakes and produce high-resolution images of its surface.

JPL notes that understanding Europa habitability will help astrobiologists to better understand how life developed on Earth approximately 382 million miles away, in addition to efforts to find life beyond the blue marble.

While JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington, NASA’s Kennedy-based Launch Services Program will manage the Europa Clipper launch service.

Additionally, the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, will orchestrate program management of the Europa Clipper mission.

Buck Moon rises over Oshawa harbour – insauga.com

Published

July’s orange- or yellow-tinted full moon – known as a Buck Moon – arrived at 10:36 p.m. Friday night.

It’s called the Buck Moon because the antlers of male deer are in full-growth mode at this time.

Indigenous people of Canada have several other names for the phenomenon, including Berry Moon (Anishinabe), Feather Moulting Moon (Cree), Salmon Moon, (Tlingit) and Raspberry Moon (Algonquin, Ojibwe).

The full moon can be viewed in all its glory until tomorrow night.
