Researchers from Western have shown that a fireball that originated at the edge of the Solar System was likely made of rock, not ice, challenging long-held beliefs about how the Solar System was formed.
Just at the edge of our Solar System and halfway to the nearest stars is a collection of icy objects sailing through space, known as the Oort Cloud. Passing stars sometimes nudge these icy Outer space talks are a welcome addition to the US-Africa Leaders Summit

President Joe Biden is hosting the Second US-Africa Leaders Summit in mid-December 2022.
The focus will be on eight areas: economic engagement; peace, security and good governance; democracy and human rights; regional and global health security (including recovery from COVID-19 and pandemic preparedness); food security; climate change; diaspora ties; and education and youth leadership. China launches two space experiment satellites

China on Monday launched a Long March-4C rocket, placing a pair of satellites in space.
The rocket blasted off at 4:22 pm (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China and sent the satellites Shiyan-20A and Shiyan-20B into preset orbit.
Shiyan means "experiment" in Chinese. The two Shiyan-20 satellites will be used for in-orbit verification of new technol US conducts successful hypersonic missile test: Air Force

The US Air Force announced Monday it successfully tested a hypersonic missile, a cutting edge strategic weapon that is also being developed by China and Russia.
The AGM-183A Air-launched Rapid Response Weapon (ARRW) was launched from a B-52H bomber on Friday off California's coast and "reached hypersonic speeds greater than five times the speed of sound, completed its flight path and detonat Asteroid Ryugu samples continue to shed light on solar system history

Nearly two years after Japanese mission Hayabusa2 returned to Earth, samples from asteroid Ryugu continue to reveal valuable information about the history of the early solar system. A study by scientists from the Institut de Physique du Globe de Paris, Universite Paris Cite and CNRS1, as part of an international consortium, reveals the isotopic composition of zinc and copper of asteroid Ryugu.

NASA will start hot fire testing for the production of new RS-25 engines that will power future Artemis missions to the Moon, and eventually Mars.
The initial single-engine hot fire test Wednesday, at Stennis Space Center near Bay St. Louis in Mississippi, will run for 500 seconds starting at 2 p.m. CST.

Nigeria and Rwanda became the first and second African countries to sign NASA's Artemis Accord Tuesday.
They are the 22nd and 23rd countries to sign the accord overall. The cooperation between U.S. and African space agencies comes with a pledge to advance space exploration and address issues on Earth such as climate change and the global food crisis.

Europe’s all-new weather satellite takes to the skies With success of Artemis I, when will NASA fly Artemis II?
Tuesday, 13 December 2022 17:10 Write a comment
With Orion safe back on Earth, the last and most important tests of the Artemis I mission have been completed, but there are still miles to travel and months of data sifting to go before NASA will target an Artemis II launch date.
While the latest announced timeline for that flight is no earlier than May 2024—only 18 months away—NASA officials after Sunday's successful landing kept referring a two-year turnaround between Artemis I and II, which would put its launch closer to the end of 2024.
"I think one thing we've always been concerned about is, what do we learn from [Artemis I] and are there changes we have to make? I think we've learned a lot," said Jim Free, NASA's associate administrator for the Exploration Systems Development Mission Directorate during a post-landing press conference Sunday.
"We obviously want to try to do it quicker," Free said, and pointed out the Orion team is "always looking to ways to do things quicker. We're trying to roll in lessons learned from the processing of the Artemis I vehicle at Kennedy. Are there things we can shorten there? Optimize? So that's all of our lessons learned path going forward.
