2 defunct satellites orbiting Earth at risk of colliding

‘This is uncomfortably close’: 2 defunct satellites orbiting Earth at risk of colliding, but they could also just pass dangerously close to one another, says private satellite-tracking firm LeoLabs

Two defunct satellites orbiting Earth are at risk of colliding on Wednesday, according to private satellite-tracking company LeoLabs, though they may just simply pass dangerously close to each other.

Should the pair collide, they could potentially create hundreds of pieces of space debris that would threaten other satellites in a similar orbit.

The first satellite, the Infrared Astronomical Satellite (IRAS), a joint venture between NASA and the Netherlands Agency for Aerospace Programmes, was launched in 1983 and is roughly 954 kilograms. The second, smaller GGSE-4 (also known as POPPY 5B) was launched by the U.S. Naval Research Laboratory in 1967 and weighs about 85 kilograms.

Both are now inoperative.

Alan DeClerck, vice-president of business development and strategy for LeoLabs, told CBC News the satellites could miss one another by roughly 15 to 30 metres and that there is a 1 in 100 chance of a collision at a breakneck speed of 14.7 km/s. It would occur 900 kilometres above Pittsburgh at 6:39 p.m. ET.

“In terms of normal operations satellites, one in 10,000 is considered something that you want to take a very close look at. One in 1,000 is considered an emergency,” said DeClerck. “One in 100 is something that any operator would certainly want to do manoeuvre around.”

LeoLabs is a private company with radar in Alaska, Texas and New Zealand capable of tracking satellites and space debris roughly 10 centimetres in diameter. It has plans to track debris as small as about two centimetres in diameter.

In an email statement from a NASA spokesperson to CBC News, the U.S. air force’s Combined Space Operations Center, which is responsible for tracking satellites, has yet to inform the space agency of any pending collision.

However, DeClerck, said the air force doesn’t track satellite debris, which is what the two defunct satellites would be considered.

And according to Jonathan McDowell, an astronomer at Harvard-Smithsonian Center for Astrophysics, who has been closely monitoring the situation, that might be because there are some uncertainties and that not all models will produce the same result.

“The uncertainty on the miss distance is greater than the miss distance,” McDowell said. “We’re in an era now where there are several independent companies as well as the Air Force that track satellites, and their solutions often don’t quite agree at the kilometre level.”

Using what McDowell said is the less reliable public data supplied by the Air Force on satellite orbits, he made his own calculations and got a miss distance of one-and-a-half kilometres, plus-or-minus two kilometres.

“The best thing to say is that this is uncomfortably close,” he said. “It’s more likely there not to be a collision than there will be, but at the same time, a collision wouldn’t be astonishing. So we’ve got to watch it very closely and see if we see any debris afterwards or change in the satellites’ orbits.”

McDowell said there’s one other thing to take into account.

GGSE-4 has 18-metre-long protruding booms, which he doesn’t think are factored into the calculations. Even if those booms do strike the larger IRAS, it’s unclear what that would even do.

DeClerck said LeoLabs will continue to monitor the orbits in the coming hours of the time of closest approach (TCA), and there could be revisions to the orbits. And after the TCA, they will likely know within hours what actually occurred.

If the satellites do collide and produce debris, it won’t be a major addition to the 18,000 pieces of debris currently being tracked, McDowell said, but it could generate about 1,000 more.

But what it does is up the chance of further collisions for satellites in the popular type of orbit called sun-synchronous.

If you’re concerned about pieces falling out of the sky, you needn’t worry: the threat is only to satellites.

“It’s not a things-falling-out-of-the-sky-on-our-heads situation,” McDowell said. “It’s just an increase-in-the-amount-of-ambient-space-debris-in-a-particularly-valuable-orbit kind of thing.”

Concordia researchers planning resilient, net-zero cities of tomorrow

For MonSFFen, more ideas for the “cities of the future” panel. The library in Varennes, mentioned in this article, produces about the same amount of energy as it consumes. –CPL

In order to reach targets of reducing greenhouse gas emissions by at least 80 per cent by 2050, the buildings, neighbourhoods and cities of tomorrow must be conceived today. Researchers at Concordia University in Montreal are taking a leading role in strategizing a net-zero future where communities are resilient — able to use available resources to withstand adverse situations — and energy is renewable.

Concrete that can grow and heal itself

Franken-concrete comes to life to create self-healing buildings.

A team of American researchers has developed a new kind of biological concrete that could redefine what we mean by “green buildings.”

The concrete, developed by researchers at the University of Colorado, Boulder, uses bacteria as a binder. This leads to a material that can grow and even heal itself — much like a living organism.

Astronomers have discovered four new and mysterious objects orbiting the Milky Way’s supermassive black hole, Sagittarius A*. The bizarre objects look a lot like common clouds of gas and dust, but they surprisingly manage to stay compact like stars as they run laps around our galaxy’s gargantuan black hole.The quartet of new objects share striking similarities with two others, dubbed G1 and G2, that were found in the past 15 years or so. This has led researchers to conclude the four new bodies likely belong to the same class of objects as G1 and G2, which are simply referred to as G-sources or G-objects.

Researchers don’t yet know exactly what these G-objects are, but they think the strange bodies might be binary stars in the process of merging.

According to new research, Proxima c has a minimum mass of about 6 Earth masses, and it orbits its red dwarf host star once every 5.2 years — Lorenzo Santinelli

Our nearest celestial neighbor, the star Proxima Centauri, likely has a second planet.

The planet, dubbed Proxima c, is at least about 6 times the mass of Earth and orbits its tiny red dwarf host once every 5.2 years. If confirmed, the newly discovered super-Earth would be the second terrestrial world found in the Proxima Centauri system, which is located just 4.2 light-years from Earth.

According to the researchers, the discovery of Proxima c could provide insights into how low-mass planets around low-mass stars form, especially when the planets begin their lives well beyond a star’s “snow line,” where water turns to solid ice.

Designs for the future

MonSFFA is planning presentations on mega cities, designs for the future–the dreams we had in the past, the dreamers of today.

In today’s Montreal Gazette there was an article about future transportation: Flying taxis & rail loops with cities for stops .

I found a video for the flying Uber here.

TRANSPORT’S FUTURE IS NOW IN CALIFORNIA
 Uber Air is testing its flying taxi service in San Diego and will launch services in 2023 in Los Angeles, Dallas and Melbourne.

This city sprawls across five counties with an exploding population of 14 million. Its roads are now so choked that this fall Uber, Lyft and taxis were banned from picking up people at its crowded airport. Now arriving passengers must wait, then board shuttle buses to go to remote parking lots to find rides.

TOMOHIRO OHSUMI/BLOOMBERG FILES The transition to autonomous or self-driving cars is gathering speed, and flight and rail are on their way to being transformed. Uber Air plans to launch its flying taxi service in 2023 in Los Angeles, Dallas and Melbourne. The EVTOLs, or electrically powered vertical take-off and landing drones, will make short-haul flights at low altitudes.

So it’s hardly surprising that California is where 22nd century transportation modes are being invented. And those of us at this week’s high-level Abundance360 conference hosted by tech pioneer (and a friend) Peter Diamandis learned that the “robots” that will transport us and everything are coming in a handful of years.

The transition to autonomous or self-driving cars gathers speed. They are permitted in 29 states, with testing permits, while Tesla and others offer partial self-driving features with drivers onboard. But by the end of 2020, Elon Musk will roll out a fully automated version of Tesla which, he claims, will prove that such cars are three to four times safer than human drivers.

With trust in the tech, adoption will leap. Cars or drones on wheels will drive the elderly to doctor’s appointments or children to school or commuters to work while they work or watch television or sleep.

Besides that, flight and rail will also be transformed. Uber Air is testing its flying taxi service in San Diego and will launch services in 2023 in Los Angeles, Dallas and Melbourne. Most important, the FAA, or Federal Aviation Administration, has given a theoretical green light for these low-altitude commuter services along selected air routes, pending trials.

Uber will offer short-haul flights at low altitudes between sky ports that will be built or added on to existing rooftops, vacant parking lots, stadiums, or highway interchanges. Uber plans to take cars off the road and keep costs low by “batching” passengers. People will be picked up and ride-share in vehicles to a sky port for departure, then fly and ride-share from the sky port to their work destinations. The process will be reversed at the end of the workday.

“These are not helicopters, which are unsafe, noisy and expensive,” said Nikhil Goel, head of product development at Aviation Uber. They are EVTOLs, or electrically powered vertical take-off and landing drones, with noise-proof rotors that allow them to vertically take off, then fly between sky ports.

In case of viagra for cheap prices https://unica-web.com/archive/2018/unica2018-entries.html unavailability at the medical shop, one can go with online pharmacies that will offer you Kamagra, and it is up to you to find the right one.

Individuals using the product might experience certain mild effects such as headache, nasal congestion, runny nose or fatigue during the course period and these effects are very mild, generic tadalafil no prescription normal and tolerable.

“A helicopter cost is $10 per mile,” he said, “but with batching (of passengers) to and from sky ports we can get that cost down to $1.50 per mile.”

The ultimate goal is to get cars off the road by making it faster and cheaper to fly than to own a car to commute. Last year, billions were raised for development by various companies and the first one was listed on Nasdaq. Joint ventures between flying car companies like Uber and Joby and giant automakers like Hyundai and Toyota are moving quickly.

“It’s two hours from JFK Airport to Manhattan by car and less than 10 minutes flying,” said Goel.

Such aircraft will also be able to carry cargo and to deliver emergency supplies or ambulance services quickly.

Another Los Angeles pioneer is Virgin Hyperloop One, which will revolutionize railways by moving passengers and freight through concrete tunnels at the speed of aircraft.

Virgin’s CTO Josh Giegel said the company is working on nine projects and 400 test pilots, and expects several lines to be built this decade. These rail systems will link cities, and could be tunnelled, or built above ground along existing highway medians.

“Hyperloop would turn cities into stops,” said Giegel. “For instance, Chicago, Columbus and Pittsburgh would be 30 minutes apart.”

These companies will allow cities to reach their goal of getting cars off the road this decade. The only obstacle in their path will be political will and foresight.

Obituary

Christopher Tolkien (1924-2020)

Christopher Tolkien has passed away. Obituary below is copied from Locus Magazine.

Author and editor Christopher Tolkien, 95, son and literary executor of J.R.R. Tolkien, died January 15, 2020 in Provence, France. Tolkien dedicated his life to his father’s work, editing and shepherding into print more than a score of the elder Tolkien’s books. He organized and edited the The Silmarillion (1977), Unfinished Tales (1980), and the 12 volumes of The History of Middle-earth (1983), along with The Children of Húrin (2007), The Legend of Sigurd and Gudrún (2009), The Fall of Arthur (2013), Beowulf: A Translation and Commentary (2014), Beren and Lúthien (2017), and The Fall of Gondolin (2018). He was chairman of the Tolkien Estate, Ltd. and a trustee of the Tolkien Charitable Trust. He also drew the iconic map of Middle-earth included in the 1954 edition of The Lord of the Rings, and the updated 1970s version. He retired as director of the estate in 2017.

Tolkien received the 2017 Bodley Medal in part for his work editing the unpublished texts of his father. The medal was given by the Bodleian Libraries at Oxford University, where the Tolkien Archive has been housed since 1973.

Tolkien was to married to Faith Faulconbridge from 1951-1967 and they had one child, Simon. He remarried the same year to Baillie Klass, with whom he had two children, Adam and Rachel. Tolkien eventually moved with his family to France and became a citizen there. He is survived by his wife, sister Priscilla, and three children.
