In a concept test for an advanced planetary defense solution.
We are vastly unprepared for the event of an impending, potentially civilization-ending asteroid impact. Knowing this, NASA is developing planetary defense solutions to add to its arsenal of space technologies.
One of these technologies, NASA’s DART spacecraft, is scheduled to launch aboard a SpaceX Falcon 9 rocket at 10:20 Pacific time on November 23 a press statement reveals. … See more.
“We think between now and the end of 2,022 this is the point where we get control over this virus … where we can significantly reduce severe disease and death,” Maria Van Kerkhove, an epidemiologist leading the World Health Organization’s (WHO) COVID-19 response, told Reuters.
CHICAGO, Nov 3 (Reuters) — As the devastating Delta variant surge eases in many regions of the world, scientists are charting when, and where, COVID-19 will transition to an endemic disease in 2022 and beyond, according to Reuters interviews with over a dozen leading disease experts.
They expect that the first countries to emerge from the pandemic will have had some combination of high rates of vaccination and natural immunity among people who were infected with the coronavirus, such as the United States, the UK, Portugal and India. But they warn that SARS-CoV-2 remains an unpredictable virus that is mutating as it spreads through unvaccinated populations.
None would completely rule out what some called a “doomsday scenario,” in which the virus mutates to the point that it evades hard-won immunity. Yet they expressed increasing confidence that many countries will have put the worst of the pandemic behind them in the coming year.
NASA planetary defender Dr. Kelly Fast has a hard and fast rule: “Find asteroids before they find us.” Working in NASA’s Planetary Defense Coordination Office, Kelly is helping send the #DARTMission to test “nudging” an asteroid in space. DART, short for Double Asteroid Redirection Test, is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous near-Earth object. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space. NOTE: the target asteroid is currently not a threat to Earth.

“De-Extinction” Biotechnology & Conservation Biology — Ben Novak, Lead Scientist Revive & Restore
Ben Novak is Lead Scientist, at Revive & Restore (https://reviverestore.org/), a California-based non-profit that works to bring biotechnology to conservation biology with the mission to enhance biodiversity through the genetic rescue of endangered and extinct animals (https://reviverestore.org/what-we-do/ted-talk/).
Ben collaboratively pioneers new tools for genetic rescue and de-extinction, helps shape the genetic rescue efforts of Revive & Restore, and leads its flagship project, The Great Passenger Pigeon Comeback, working with collaborators and partners to restore the ecology of the Passenger Pigeon to the eastern North American forests. Ben uses his training in ecology and ancient-DNA lab work to contribute, hands-on, to the sequencing of the extinct Passenger Pigeon genome and to study important aspects of its natural history (https://www.youtube.com/watch?v=pK2UlLsHkus&t=1s).

One of the deepest realizations of the scientific understanding of the world that emerged in the 18th and 19th century is that the world is changing, that it has been radically different in the past, that it can be radically different in the future, and that such changes could spell the end of humanity as we know it. An added twist arrived in the 20th century: we could ourselves be the cause of our demise. In the late 20th century an interdisciplinary field studying global catastrophic and existential risks emerged, driven by philosophical concern about the moral weight of such risks and the realization that many such risks show important commonalities that may allow us as a species to mitigate them. For example, much of the total harm from nuclear wars, supervolcanic eruptions, meteor impacts and some biological risks comes from global agricultural collapse. This talk is going to be an overview of the world of low-probability, high-impact risks and their overlap with questions of complexity in the systems generating or responding to them. Understanding their complex dynamics may be a way of mitigating them and ensuring a happier future.

According to astronomers, several asteroids with diameters more than 10 meters collide with the surface of the solar system’s largest planet every year, causing explosions visible from Earth. Previously, such collisions were registered in 1,994 2009, 2,010 2012, 2,016 2017 and 2019.
If confirmed, this will be the ninth recorded impact on Jupiter since the first in July 1,994 when Comet Shoemaker-Levy 9 shattered into several smaller pieces, sinking one after another into the giant’s gas shell, leaving dark marks on the clouds of Jupiter, some of them the size of our planet.

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way.
The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It’s one large-ish asteroid, approximately 780 meters across — that’s Didymos proper — and a 160-meter “moonlet” in its orbit.
As the moonlet is more typical of the type likely to threaten Earth — there being more asteroids that are that size and not easily observed — we will be testing the possibility of intercepting one by smashing into it at nearly 15,000 miles per hour. This will change the speed of the moonlet by a mere fraction of a percent, but enough that its orbit period will be affected measurably. Knowing exactly how much will help us plan any future asteroid-deflection missions — not surprisingly, there isn’t a lot of existing science on ramming your spacecraft into space rocks.
North Korea fired at least one ballistic missile from its eastern coast on Tuesday morning, according to South Korean and Japanese officials.
The launch took place in the port city of Sinpo, Hamgyong province, at about 10 a.m. local time Tuesday (9 p.m. ET Monday), South Korea’s Joint Chiefs of Staff (JCS) said. In a text to reporters, the JCS said it appeared to be a submarine-launched ballistic missile (SLBM).
South Korea’s Defense Ministry said the missile is estimated to have been fired from the sea, but has yet to confirm whether it was launched from a submarine. Sinpo is home to a North Korean naval shipyard.

In February of 2,013 skywatchers around the world turned their attention toward asteroid 2012 DA14, a cosmic rock about 150 feet (50 meters) in diameter that was going to fly closer to Earth than the spacecraft that bring us satellite TV.
Little did they realize as they prepared for the once-in-several-decades event that another bit of celestial debris was hurtling toward Earth, with a more direct heading. On February 15 2013, the Chelyabinsk meteor, a roughly 62-foot (19 meter)-diameter asteroid exploded over the city of Chelyabinsk, Russia, as it entered Earth’s atmosphere at a shallow angle. The blast shattered windows and damaged buildings, and nearly two thousand people were hurt, though thankfully no one died.
