Every two years scientists, space agencies and civil protection organizations gather for five days of asteroid impact drills. This week marks the seventh Planetary Defense Conference, held virtually to comply with pandemic considerations. From April 26 – 30, 2021 fictitious asteroid PDC 2021 measures are live streamed by ESA (European Space Agency). Fascinating stuff, well worth consideration. Below. link to asteroid impact drill overview from NASA, followed by several links to watch in real time from ESA –
This week, experts are meeting at the #PlanetaryDefense Conference for a pretend asteroid impact. Why? So, in the unlikely event it does happen, we'll be ready.☄️
On March 19, 2021 Iceland’s Geldingadular volcano woke from a six thousand year slumber. A relatively minor eruption, more curiosity than threat by Icelandic standards despite being 20 kilometers from Reykjavik. Burping Geldingadular isn’t far from the Blue Lagoon, a man-made geothermal spa fed by water from a nearby power plant. Blue Lagoon (geothermal spa) – Wikipedia On March 31st, Wioleta Gorecka ran with a friend’s suggestion to capture the “big three” – volcanic eruption, aurora and the blue lagoon. Her whim took my breath away –
According to the South China Morning Post, November 17, 2019 marks the first documented case of COVID-19 in China. Impossible to say if this individual was patient zero. If we’re to believe official statements by China, infections grew to 60 by December 20, 2019. On December 27th, Dr. Zhang Jixian, head of the respiratory department at Hubei Provincial Hospital in Wuhan, confirmed the disease was caused by a novel coronavirus. On that day, official case count stood at 160. Viral videos of Wuhan’s “wet market”, clips of fine dining delicacies like whole bats or live baby mice in broth, cemented China’s official party line – COVID can be traced to Wuhan’s wet market. China closed the market in January 2020, sanitizing it without taking samples. In May 2020, China admitted it wasn’t the market, offering no idea where it came from.
In late 2017, science and health officials from the U.S. Embassy attended a conference in Beijing. They witnessed a presentation by Chinese scientists working out of a top level bio-safety lab in Wuhan. Research indicating bat caves in Yunnan Province were probable source of the SARS outbreak and identification of three new coronavirus characterized by a “spike protein” conducive to “grabbing” on to human lung cells known as ACE2 receptors. According to Politico (article linked below) officials at the U.S. Embassy sent teams to inspect the lab on three occasions in late 2017, early 2018. The article alleges – “When they sat down with the scientists at the WIV, the American diplomats were shocked by what they heard. The Chinese researchers told them they didn’t have enough properly trained technicians to safely operate their BSL-4 lab. The Wuhan scientists were asking for more support to get the lab up to top standards.” Shocked enough to alert Washington, warn of potential implications and call for immediate assistance to meet safety standards. Pleas lost in a quagmire of political posturing. A warning no one listened to?
Not so fast. Since when does China allow top level bio-security scientists to speak off the record to U.S. diplomats? Admit they’re incapable of managing containment and security?
Much as I’m leaning toward credibility of a lab breach and cover-up, I struggle with accuracy of Politico’s account. Read the article and let me know what you think.
Last week Adrien Mauduit took Night Lights Films to a beach in Norway. Ethereal aurora paid little attention to waves caressing a pebbled shore. Unexpected, hypnotic and awe inspiring.
Who knew aurora at the beach had more to give? Sea ice bioluminescence took my breath away. Hats off to Adrien Mauduit –
New research published in the journal Science Advances supports a correlation between moon cycles and sleep. Seems we go to bed later, sleep less when the moon is full. Scientists analyzed sleep patterns of two control groups, one in rural Argentina without artificial light pollution, the other college students living in downtown Seattle. Research concluded full moons disrupt sleep patterns even in urban locations with artificial light pollution. Participants wore wristbands to monitor activity, both groups went to bed later, slept less during the week leading up to a full moon. Research confirmed humanity’s inherent link to evolutionary circadian rhythms.
Circadian rhythm regulates wake/sleep hours, repeating once every 24 hours in step with rotation of Earth. Circadian (from Latin “circa” meaning around or approximately and “diem”, meaning day ) rhythm is hard wired into every form of life. It dictates when bees feed, bats fly and we sleep. Circadian rhythm is sensitive to light fluctuation – enter full moon sleep deprivation.
As I write, Earth directed solar wind blows at 559.3 km/second. High speed solar wind is credited to sunspot AR2803 –

Last night, Adrien Mauduit at Night Lights Films captured “Aurora at the Beach”, mesmerizing real time aurora majesty washed in waves tickling a stony beach. Treat yourself to Aurora at the Beach, follow Adrien Mauduit at Night Lights Films. –
Below – screenshot of the current Aurora Oval illustrating the impact of high speed solar wind from AR2308. Centered at true magnetic North rather than geographical North Pole, the Aurora Oval widens or retreats at the command of space weather.

Once a planet Pluto marks its 91st anniversary of discovery on February 18, 2021. Take a moment to ponder 91 years of Pluto from discovery to New Horizons mission majesty. Kudos Pluto, your presence is a source of infinite wonder. It’s remarkable to consider Pluto, a solar system constant, has only been known for 91 years. Arizona’s Lowell Observatory is recognized as the birthplace of Pluto. From – Celebrate the 91st anniversary of Pluto’s discovery | Human World | EarthSky –
“Lowell Observatory bills itself as the the “Home of Pluto.” Percival Lowell, a wealthy American businessman with a passion for astronomy, postulated the existence of a “trans-Neptunian object” and searched for it until his death in 1916. His estate, managed by Lowell’s brother, Harvard University president A. Lawrence Lovell, donated money for a new telescope that still stands at the current Lowell Observatory. Using this telescope, Clyde Tombaugh continued Lowell’s search. On February 18, 1930, he detected movements on photographic plates taken in late January. The discovery was announced on March 13, 1930, on what would have been Lowell’s 75th birthday.”

Does Pluto love us back? It almost seems to, with this giant heart on the surface! This image was taken by the New Horizons mission on July 13, 2015. Here are 10 cool things about Pluto you might not know. Image via NASA/ APL/ SwRI.
Roughly seven months ago the U.S., China and United Arab Emirates took advantage of favourable Earth/Mars orbit to launch missions to Mars. Over the next two weeks all three, one orbiter and two landers will reach Mars. Ponder the enormity of three nations, three separate missions congregating at Mars within days of each other. Who knew the UAE has a space program? Why is China poking at Mars? How many people still believe space exploration starts and ends with NASA? Who even knows how many separate space missions are active?
The UAE arrives first on February 9th. The EMM (Emirates Mars Mission) probe Amal is an orbiter tasked with collecting atmospheric data. The UAE space program is an initiative to advance science and technology rather than reliance on oil. The very next day China’s Tianwen-1, a dual orbiter/lander mission settles into orbit. If all goes well, Tianwen-1 will deploy its solar powered lander sometime in May. This is China’s second attempt to deploy a Mars lander, their 2011 joint venture with Russia failed. On February 18 NASA’s Perseverance Rover skips orbit for immediate deployment to the Jezero Crater, an ancient river delta which flowed into a lake. NASA is the only space agency to successfully land on Mars. (Eight times since 1976 )
The Apollo era cemented universal cosmic wonder. The enormity of space travel, realization of science fiction becoming reality resonated with collective astonishment. Tonight I write of three autonomous Mars missions arriving within days of each other knowing full well most people aren’t interested. Today, cosmic wonder languishes in a puddle of competing click bait, occasionally bubbling to the surface when news feeds pluck near Earth asteroid calamity froth. Missions to Mars aren’t enough to attract clicks and views. Cosmic wonder suffers in silence.
Ring in the New Year with a nod to Sirius, brightest star in the night sky. Residing in constellation Canis Major, Sirius often answers to the name Dog Star. Tonight and every New Years Eve, Sirius reaches its highest point near the strike of midnight making it the New Years star. Tipping your hat to Sirius is as simple as spotting Orion’s iconic belt –
This photo comes from EarthSky Facebook friend Susan Jensen in Odessa, Washington. See how it matches the chart above, with the 3 stars of Orion’s Belt pointing to Sirius?
Independent of each other, every ancient civilization from Egypt to Sumeria, Babylon and Greece revered sparkling Sirius. As we tread softly into 2021, think of Sirius as an astronomical foundation acknowledged through the ages. Resolve to gaze upward on a clear dark night, follow Orion’s belt to Sirius and smile. Happy New Year.
