Starlink brings the world to rural Highlanders – Haliburton County Echo

Published

By Darren Lum

High speed internet is here for rural residents through Starlink, an effort being led by the private spaceflight company owned by Elon Musk, SpaceX.
SpaceX is constructing a satellite internet constellation to provide high-speed service access via a connection with ground receivers in low to medium population density communities around the world.

The product development for Starlink started in 2015 and launched its 60 first low-Earth orbit, or LEOs, part way through 2019. More and more satellites are being launched, as part of a plan to form a megaconstellation, comprising of thousands of mass-produced small satellites that will orbit 550 kilometres from earth.

Currently, Starlink is in its beta stage and is offering the public an opportunity to connect through invites after they have submitted an online application.

It’s unknown how many beta users are in the Highlands, but for the few who are involved it has been largely positive results after spending close to $800 for the hardware (receiver, router, cable and hardware for installation) with tax and shipping, and the $129 monthly connection fee.
Bill Donnery, a retired resident who lives on Ritchie Falls Road with his wife, has been using Starlink for the past three weeks.

“I was just fortunate enough to get in on it so I jumped at the chance. I’m very happy with it,” he said.

Donnery, who said his internet use is mostly for entertainment – made up mostly of streaming services such as Netflix, and video chatting with loved ones, mounted his Starlink dish on his roof in place of where his satellite dish for television was. He’s among the select few not just in Haliburton County, but the country selected as beta users, who will provide information for Starlink .

When he first received it after a four-day journey from California he put it out on his driveway to test it and had internet connection within 10 minutes.

“It’s pretty simple. You plug it in and it finds its own satellite itself and rotates and tilts and within five or ten minutes you’re online,” he said.
He adds his highest speed recorded through an app on his phone has been 175 mbps and the low has been 35 mbps, while the latency is between 20 and 40.

Donnery said he’s only experienced the internet connection being down for up to three minutes in a day.

“The biggest thing is no cap. You don’t have to worry about going over your limit. High speed unlimited internet,” he said.

Donnery’s been living there in the home he built since 1984 and his internet connection started with dial-up with Bell to Xplornet satellite in the early-2000s to now using a wireless network. The speed of his connectivity has ranged from two or three mbps with satellite to 20 to 25 mbps with wireless.

“This seems too good to be true,” he said, referring to seeing the 150 mbps speed.

Using cellular connection is expensive with five gigabytes costing $60 and could go up from there. Recently, a new a new rate during the pandemic was offered, which saw him pay $120 for 50 gigabytes. However, sometimes speed with Rogers was halved during the summer when there were more users.

He appreciates the dishes’ heating feature that melts the snow so he doesn’t have to go up to his roof to clear it after a snow event.

Across Haliburton County, Moore Falls resident Richard Bradley was amazed by the connection he had within a few minutes after he placed the Starlink dish, which is similar to a size of a pizza, on his picnic table.
He loves how much clearer everything is when he watches the Toronto Maple Leafs play after he received it close to a month ago now.

“To watch a Leaf game and not have to set my TV to 240p so everything looks like sort of an interesting colouration of check-boards … Now when I put it on auto when I connect to Sportsnet or TSN or whatever, for a hockey game … more often than not, it selects 720p high definition. Obviously it does a speed test to decide,” he said.

Bradley, with two other users in the house, said there has been some down times of connection during virtual meetings that need a live feed without buffering, but he’s “willing to look past” it. Part of this will be resolved with higher placement of the dish to avoid obstruction of sight to the sky by the trees in his yard, he adds. Bradley said he’ll wait for the spring to install the dish higher on his house. He wishes he could have had an option for a different length cable between the dish and the router and you didn’t need to dismantle the dish to remove the cable.

He said the monthly cost for Starlink is comparable to what he pays now.

“If I cancel my landline and I cancel my internet with Bell, it’s almost the same price. It’s within, I dunno, $10, a month,” he said. “It’s an upgrade. I guess the real thing about the internet is we’ve already decided it’s not a fad. It’s not going away. So all we want is better, faster and more, right?”

Starlink uses beta users to evaluate connections.

As far as any concerns about being monitored, Bradley said he’s not concerned.

“I don’t distrust them any more than I distrust Bell Canada. You know what? Whoever your service provider is … they can monitor whatever traffic [you have]. It’s all going through their system and they all have access,” he said.
Recently, Musk posted to social media that speeds will double later this year to 300 mbps and said latency – the amount of delay for a internet network, defining how much time it takes a signal to travel back and forth from a destination – will drop to 20ms later in the year. He’s also said Starlink will reach customers around most of the earth by the end of this year and have complete global coverage by next year.

Musk added “Important to note that cellular will always have the advantage in dense urban areas. Satellites are best for low to medium population density area.”

Amanda Conn, executive director with the Haliburton Highlands Chamber of Commerce, acknowledges Musk can come off as boastful, but doesn’t discount his abilities and track record success.

“Even when he makes these claims that sound a little like crazy and outlandish at the time, he has been able to make a lot of them come true to some extent,” she said.

Conn, who lives in a wood area west of Carnarvon, is expecting to have her hardware soon after placing an order on Tuesday, Feb. 23.

The issue for her isn’t access so much as gaining a stable a connection.

“When it comes to connectivity it’s not just getting access to that connectivity, but it’s also getting access to stable connectivity, which I don’t know if in the beta Starlink they will have,” she said.

Her challenge with her connectivity is having video conferences where she can see herself moving.

“Seeing other people isn’t the … problem, but it’s more so you’re always frozen,” she said.

She is currently connected using satellite and LTE through her phone, as her location precludes her using Bell or North Frontenac Telephone Company [NFTC].

There’s been great anticipation for Starlink.

“I’ve heard great things, which is why I’m so excited, but as more and more people join I think we need to see how it actually works. I’m afraid of putting all my eggs in one basket without actually seeing the evidence,” she said.

The past few years, her dependency on connectivity has increased and, although it’s effectiveness fluctuated, it has improved with what she currently relies on for internet.

“I’ve seen an increase in their service in the last couple of years so there has been increases there, but this seems to be a big jump forward. It make all those things that are really difficult right now a lot easier,” she said.

She adds while video conferencing for work all day included acceptable audio, it also included frozen video images of her.

Internet access at her house of five users goes beyond work applications she said.

“It’s not just for work right now. Everyone is so far away and unable to be with their family so I think that is a huge part of it too. That social connection, especially over the last year,” she said.

Despite all the benefits and positive aspects that come with Starlink, there is a caveat.

“As more and more people are accessing the network and how it’s scaled up to millions of users they ultimately want to have, I think that is going to be important to keep an eye on,” she said.

She adds at some point there will be a limit to how many satellites will be allowed to meet the demands.

There’s an obvious high cost for this service that not everyone in the county can afford, she adds. It would be ideal if a solution that was accessible to everyone was available.

Also, Conn wishes there could be a local option.

“While we would love it to be a Canadian company that is offering that technology, you know, anything that we can do to help connect more people up here the better,” she said. “That’s going to help the businesses.”

She hopes her experience will not just benefit her, but will provide a perspective she could share with chamber members.

“If I have a great experience, probably, other businesses are asking for suggestions and solutions I would be more than happy to share that information with them and share my own personal experience. I don’t think it’s something the chamber needs right now because we are located downtown Haliburton so we do have access to infrastructure,” she said.
She believes this connectivity isn’t just good for businesses when it can enable more opportunities to new and more business, but also benefit their employees.

“If we have a period of time where people need to work from home or want to work from home and have better connectivity to do so I think that helps a business as a whole be more productive,” she said.

"Hi, It's Me": NASA's Voyager 1 Phones Home From 15 Billion Miles Away – NDTV

Launched in 1977, Voyager 1 was mankind’s first spacecraft to enter the interstellar medium

Washington, United States:

300x250x1

NASA’s Voyager 1 probe — the most distant man-made object in the universe — is returning usable information to ground control following months of spouting gibberish, the US space agency announced Monday.

The spaceship stopped sending readable data back to Earth on November 14, 2023, even though controllers could tell it was still receiving their commands.

In March, teams working at NASA’s Jet Propulsion Laboratory discovered that a single malfunctioning chip was to blame, and devised a clever coding fix that worked within the tight memory constraints of its 46-year-old computer system.

window._rrCode = window._rrCode || [];_rrCode.push(function() (function(v,d,o,ai)ai=d.createElement(“script”);ai.defer=true;ai.async=true;ai.src=v.location.protocol+o;d.head.appendChild(ai);)(window, document, “//a.vdo.ai/core/v-ndtv/vdo.ai.js”); );

“Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems,” the agency said.

“The next step is to enable the spacecraft to begin returning science data again.”

Launched in 1977, Voyager 1 was mankind’s first spacecraft to enter the interstellar medium, in 2012, and is currently more than 15 billion miles from Earth. Messages sent from Earth take about 22.5 hours to reach the spacecraft.

Its twin, Voyager 2, also left the solar system in 2018.

Both Voyager spacecraft carry “Golden Records” — 12-inch, gold-plated copper disks intended to convey the story of our world to extraterrestrials.

These include a map of our solar system, a piece of uranium that serves as a radioactive clock allowing recipients to date the spaceship’s launch, and symbolic instructions that convey how to play the record.

The contents of the record, selected for NASA by a committee chaired by legendary astronomer Carl Sagan, include encoded images of life on Earth, as well as music and sounds that can be played using an included stylus.

window._rrCode = window._rrCode || [];_rrCode.push(function(){ (function(d,t) var s=d.createElement(t); var s1=d.createElement(t); if (d.getElementById(‘jsw-init’)) return; s.setAttribute(‘id’,’jsw-init’); s.setAttribute(‘src’,’https://www.jiosaavn.com/embed/_s/embed.js?ver=’+Date.now()); s.onload=function()document.getElementById(‘jads’).style.display=’block’;s1.appendChild(d.createTextNode(‘JioSaavnEmbedWidget.init(a:”1″, q:”1″, embed_src:”https://www.jiosaavn.com/embed/playlist/85481065″,”dfp_medium” : “1”,partner_id: “ndtv”);’));d.body.appendChild(s1);; if (document.readyState === ‘complete’) d.body.appendChild(s); else if (document.readyState === ‘loading’) var interval = setInterval(function() if(document.readyState === ‘complete’) d.body.appendChild(s); clearInterval(interval); , 100); else window.onload = function() d.body.appendChild(s); ; )(document,’script’); });

Their power banks are expected to be depleted sometime after 2025. They will then continue to wander the Milky Way, potentially for eternity, in silence.

West Antarctica's ice sheet was smaller thousands of years ago – here's why this matters today – The Conversation

Published

 on


As the climate warms and Antarctica’s glaciers and ice sheets melt, the resulting rise in sea level has the potential to displace hundreds of millions of people around the world by the end of this century.

A key uncertainty in how much and how fast the seas will rise lies in whether currently “stable” parts of the West Antarctic Ice Sheet can become “unstable”.

One such region is West Antarctica’s Siple Coast, where rivers of ice flow off the continent and drain into the ocean.

This ice flow is slowed down by the Ross Ice Shelf, a floating mass of ice nearly the size of Spain, which holds back the land-based ice. Compared to other ice shelves in West Antarctica, the Ross Ice Shelf has little melting at its base because the ocean below it is very cold.

Although this region has been stable during the past few decades, recent research suggest this was not always the case. Radiocarbon dating of sediments from beneath the ice sheet tells us that it retreated hundreds of kilometres some 7,000 years ago, and then advanced again to its present position within the last 2,000 years.

Figuring out why this happened can help us better predict how the ice sheet will change in the future. In our new research, we test two main hypotheses.

Testing scenarios

Scientists have considered two possible explanations for this past ice sheet retreat and advance. The first is related to Earth’s crust below the ice sheet.

As an ice sheet shrinks, the change in ice mass causes the Earth’s crust to slowly uplift in response. At the same time, and counterintuitively, the sea level drops near the ice because of a weakening of the gravitational attraction between the ice sheet and the ocean water.

As the ice sheet thinned and retreated since the last ice age, crustal uplift and the fall in sea level in the region may have re-grounded floating ice, causing ice sheet advance.

The other hypothesis is that the ice sheet behaviour may be due to changes in the ocean. When the surface of the ocean freezes, forming sea ice, it expels salt into the water layers below. This cold briny water is heavier and mixes deep into the ocean, including under the Ross Ice Shelf. This blocks warm ocean currents from melting the ice.

Seafloor sediments and ice cores tell us that this deep mixing was weaker in the past when the ice sheet was retreating. This means that warm ocean currents may have flowed underneath the ice shelf and melted the ice. Mixing increased when the ice sheet was advancing.

We test these two ideas with computer model simulations of ice sheet flow and Earth’s crustal and sea surface responses to changes in the ice sheet with varying ocean temperature.

Because the rate of crustal uplift depends on the viscosity (stickiness) of the underlying mantle, we ran simulations within ranges estimated for West Antarctica. A stickier mantle means slower crustal uplift as the ice sheet thins.

The simulations that best matched geological records had a stickier mantle and a warmer ocean as the ice sheet retreated. In these simulations, the ice sheet retreats more quickly as the ocean warms.

When the ocean cools, the simulated ice sheet readvances to its present-day position. This means that changes in ocean temperature best explain the past ice sheet behaviour, but the rate of crustal uplift also affects how sensitive the ice sheet is to the ocean.

What this means for climate policy today

Much attention has been paid to recent studies that show glacial melting may be irreversible in some parts of West Antarctica, such as the Amundsen Sea embayment.

In the context of such studies, policy debates hinge on whether we should focus on adapting to rising seas rather than cutting greenhouse gas emissions. If the ice sheet is already melting, are we too late for mitigation?

We can still prevent the collapse of the West Antarctic ice sheet – if we act fast to keep future warming in check


Our study suggests it is premature to give up on mitigation.

Global climate models run under high-emissions scenarios show less sea ice formation and deep ocean mixing. This could lead to the same cold-to-warm ocean switch that caused extensive ice sheet retreat thousands of years ago.

For West Antarctica’s Siple Coast, it is better if we prevent this ocean warming from occurring in the first place, which is still possible if we choose a low-emissions future.

NASA's Voyager 1 resumes sending engineering updates to Earth – Phys.org

Published

For the first time since November, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).

Voyager 1 stopped sending readable science and engineering data back to Earth on Nov. 14, 2023, even though mission controllers could tell the was still receiving their commands and otherwise operating normally. In March, the Voyager engineering team at NASA’s Jet Propulsion Laboratory in Southern California confirmed that the issue was tied to one of the spacecraft’s three onboard computers, called the flight data subsystem (FDS). The FDS is responsible for packaging the science and engineering data before it’s sent to Earth.

The team discovered that a responsible for storing a portion of the FDS memory—including some of the FDS computer’s software code—isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.

So they devised a plan to divide affected the code into sections and store those sections in different places in the FDS. To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.

The team started by singling out the responsible for packaging the spacecraft’s engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22.5 hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22.5 hours for a signal to come back to Earth. When the mission flight team heard back from the spacecraft on April 20, they saw that the modification had worked: For the first time in five months, they have been able to check the health and status of the spacecraft.

During the coming weeks, the team will relocate and adjust the other affected portions of the FDS software. These include the portions that will start returning science data.

Voyager 2 continues to operate normally. Launched over 46 years ago, the twin Voyager spacecraft are the longest-running and most distant spacecraft in history. Before the start of their interstellar exploration, both probes flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune.
