Universe Today 19 Mar 2019, 18:50 UTC Roughly 12,800 years ago, planet Earth went through a brief cold snap that was unrelated to any ice age. For years, there have been geologists that have argued that this period was caused by an airburst or meteor fragments (known as the Younger Dryas Impact Theory). This event is beleived to have caused widespread destruction and the demise of the Clovis culture in North American.
Centauri Dreams 19 Mar 2019, 16:30 UTC Dust rings in the Solar System are of interest because they offer clues about the formation of the planets, as well as allowing us to contrast our own circumstellar dust with what we see around other stars in varying stages of planetary development. Recent work out of NASA’s Goddard Space Flight Center offers a dust ring with a difference from others we’ve found in our own system. Scientists have traced a dust ring near the orbit of Venus, and it’s one with origins different than the dust that occurs in Earth’s orbit as well as dust found near Mercury.
Sky and Telescope 19 Mar 2019, 13:52 UTC It's been 2½ months since NASA's piano-size New Horizons zipped past a tiny target in the Kuiper Belt in the first hours of New Year's Day. That body, designated 2014 MU69 and nicknamed "Ultima Thule" by mission scientists, wasn't even discovered until 8½ year after the spacecraft's launch. Since the flyby, enough observations have trickled back to Earth to start to piece together this object's remarkable story — and this week those first chapters are being presented at the annual Lunar and Planetary Science Conference.
Drew Ex Machina 19 Mar 2019, 12:56 UTC Probably one of the more overlooked Apollo missions was that of Apollo 9 launched on March 3, 1969. Coming just a couple of months after the historic voyage of Apollo 8 to the Moon, its mission in low Earth orbit did not seem all that spectacular and generated little public interest even at the time. But this mission, which tested the Lunar Module (LM) in flight with a crew on board for the first time, was a vital stepping stone for the Apollo 11 mission four months later making the successes of this and subsequent Apollo lunar landing missions possible.
SPACE.com 18 Mar 2019, 19:09 UTC Less than three months after the New Horizons spacecraft zoomed past a distant, cold space rock, scientists are beginning to piece together the story of how that object, nicknamed Ultima Thule, came to be.
NASA Space Station Blog 18 Mar 2019, 15:19 UTC The Expedition 59 crew is getting ready for the first of three spacewalks just days after the arrival of three new crew members to the International Space Station last week. All six crewmates also reviewed emergency procedures today while the new trio becomes accustomed to life on the orbital lab.
