Former Apollo Astronaut Pushes for International Commitment to Protect Earth from Killer Asteroids

Former Apollo Astronaut Pushes for International Commitment to Protect Earth from Killer Asteroids 94

There are few astronauts more respected and remembered than those who served on the Apollo missions – thirty-two military jet and test pilots who made or died training for the three-man Apollo missions that eventually sent humans to the Moon and back. When they have spoken – about space travel, the Moon, future missions, UFOs and other subjects – the world has listened. Rusty Schweickart, the Lunar Module pilot on Apollo 9, spoke recently about the need for an international commitment to protect Earth from killer asteroids. As usual, his comments are worth listening to.

“During the Apollo 9 mission we were dark-adapted for an experiment, looking at the spectacular night-time Earth, watching weather fronts, thunder storms and lightning, a really great sight out of the window. Then, who knows who said it first, but one of us said they saw a little flash down there and someone else says ‘yeah, I saw it too,’ but you wouldn’t have mentioned it if the first person hadn’t said it. And then we realized: that was a meteor, burning up below us. Wow, below us – which meant it came down through our altitude!”

A close encounter of the worst kind – an asteroid impact in space – instead became an experience that forever influenced Russell “Rusty” Schweickart. When he was selected in 1963, Rusty Schweickart was a unique member of NASA Astronaut Group 3 – the fourteen astronauts selected by NASA to succeed the two-man Gemini missions in the three-man Apollo flights that would eventually lead to a walk on the Moon. Those names are well-known to the public today — Collins, Cunningham, Gordon, Aldrin, Cernan, Chaffee to list a few – but back then they were better known in the military as fighter pilots and test pilots. Schweickart was an experienced Air Force pilot, but he was also a research scientist at the Experimental Astronomy Laboratory at the Massachusetts Institute of Technology in the fields of upper atmospheric physics, star tracking and stabilization of stellar images.

The 1969 flight of Apollo 9 was the first flight of the lunar module, piloted by Schweickart, and the first spacewalk of the Apollo missions, also by Schweickart. During a recent ESA Open Day at the European Space Agency’s ESTEC technical center in Noordwijk, The Netherlands, the former astronaut heard about the latest plans to stop asteroids like the one the Apollo 9 crew encountered before they destructively impact Earth. In 2022, NASA’s Double Asteroid Redirect Test will hit the smaller member of the Didymos binary asteroids. Then, if approved this month by Europe’s space ministers, the ESA’s Hera mission will perform a close-up survey of the asteroid and crater after impact. Schweickart says he likes the idea of a multi-spacecraft mission rather than a single asteroid-seeking rocket.

“And one of the key unknowns of the kinetic impactor technique is a term we call ‘beta’ – when we hit the asteroid, how much stuff is going to come flying off? If it’s moving at greater than escape velocity, then that adds to the momentum shifting the orbit, boosting the technique’s effectiveness. That factor depends on the asteroid’s composition and structure, and we need a close-up look to find out what that is.”

In 2002, Schweickart helped found the B612 Foundation (named for the planetoid in The Little Prince), whose primary mission is “protecting the Earth from asteroid impacts and informing and forwarding world-wide decision-making on planetary defense issues.” Since asteroids can hit anywhere on Earth, Schweickart has long advocated international cooperation in both deflecting space rocks and in determining which ones to hit. He sees the NASA/ESA tandem as the first example of this cooperation. Unfortunately, we’re barely into asteroid defection business and have no idea what an impact will do – it could actually push the space rock into a higher likelihood of impact.

“In that case the observer spacecraft would have another job to do – to switch to gravity tractor mode, using altimeters and ion engines to stay just away from the asteroid, and nudge its orbit enough to miss the keyhole as well as the planet.”

Rusty Schweickart makes it sound so easy and doable, but the former Apollo and Skylab astronaut knows the dangers of space. He was the backup pilot for Roger B. Chaffee on Apollo 1, which ended in the tragic deaths of the crew members in a ground test accident. He also knows how expensive a worldwide asteroid deflection system would be and how difficult it is to get nations to agree on anything, let alone unseen dangers from outer space. That’s why he stays involved in both the technology and the politics of space.

At 84, Rusty Schweickart is still influenced by that near-impact experience on Apollo 9. For that, we should all be grateful.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 99

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 100

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 101

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
