In 2015, Elon Musk announced that his company, SpaceX, would be deploying satellites to orbit that would provide high-speed broadband internet access to the entire world. Known as Starlink, SpaceX began deploying this constellation in May of 2019 with the launch of the first 60 satellites. As of April 22nd, a total of 422 satellites have been added to the Starlink constellation, and the response hasn’t been entirely positive.
In addition to fears that we’re adding to the problem of “space junk,” there are also those who’ve expressed concern that Starlink and other constellations could have a negative impact on astronomy. In response, SpaceX recently announced that it will be instituting changes in how the satellites are launched, how they orbit the Earth, and even how reflective they are in order to minimize the impact they have on astronomy.

Last week, the Satellite 2020 Conference & Exhibition wrapped up after four days of presentations and addresses from some of the leading experts in the telecommunications industry. As advertised, SpaceX founder Elon Musk was on hand to deliver a keynote speech in which he announced that (contrary to earlier statements) Starlink will not be spun off and become its own business enterprise.

Picture the space around Earth filled with tens of thousands of communications satellites. That scenario is slowly coming into being, and it has astronomers concerned. Now a group of astronomers have written a paper outlining their detailed concerns, and how all of these satellites could have a severe, negative impact on ground-based astronomy.

In May of 2019, SpaceX launched the first batch of satellites that will make up its Starlink constellation, thus delivering on Musk’s promise to provide broadband internet access to the whole world. Since then, the company has conducted several launches of upgraded satellites with the intent of creating a constellation of 1,584 by 2024 and 2,200 by 2027.
According to the latest statements made by Gwynne Shotwell, SpaceX’s President and Chief Operations Officer (COO), the company is considering spinning off Starlink and making it a publicly-traded company in the coming years. The announcement was made on Thursday, Feb. 6th, at a private investor event hosted by JPMorgan Chase & Co. in Miami.

SpaceX has been garnering all the headlines when it comes to satellite constellations. Their Starlink system will eventually have thousands of tiny satellites working together to provide internet access, though only 242 of them have been deployed so far. But now another company is getting on the action: OneWeb.

Note: Updates in reflect changes in the new launch time for Starlink-3. We’ll add in updated sighting opportunities as they become available.
By now, you’ve no doubt heard of (or seen) Starlink. SpaceX’s mega-satellite constellation has become a permanent fixture in our skies as of late, with several routine passes on any given week. But have you seen the supposed ‘black sheep’ of the flock, DarkSat?

For decades, scientists have been trying to figure out the minimum number of satellites that would be able to see every point on Earth. This question is motivated in part by the growing problem of space debris, but also by considerations of cost and efficiency. By the mid-1980s, researcher John E. Draim proposed a solution to this problem in a series of studies, claiming that a four-satellite constellation was all that was needed.
Unfortunately, his solution simply wasn’t practical at the time since a tremendous amount of propellant would be needed to keep the satellites in orbit. But thanks to a recent collaborative study, a team of researchers has found the right combination of factors to make a four-satellite constellation possible. Their findings could drive advances in telecommunication, navigation, and remote sensing while also reducing costs.

The year two thousand and twenty is almost upon us. And as always, space agencies and aerospace companies all around the world are preparing to spend the coming year accomplishing a long list of missions and developments. Between NASA, the ESA, China, SpaceX, and others, there are enough plans to impress even the most curmudgeonly of space enthusiasts.

In May of 2019, Elon Musk began delivering on his promise to create a constellation of satellites (named Starlink) that would offer broadband internet access. It all started with the launch of the first sixty Starlink satellites and was followed by Musk sending the inaugural tweet using the service this past October. Earlier today, another batch of Starlink satellites was sent into space as part of a live-streamed launch event.
The mission, known as Starlink-1, saw the launch of another 60 satellites from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida, atop a Falcon 9 rocket. Unlike previous launches, this mission involved the latest version of Starlink (Starlink 1.0), which feature a number of upgrades and refinements over the previous version (Starlink 0.9) and made this mission the heaviest Starlink launch to date.

In January of 2015, Elon Musk shared his vision of creating a constellation of satellites in Low Earth Orbit (LEO) that would provide broadband internet access to the entire planet. Back in May, SpaceX launched the first batch of 60 Starlink satellites to orbit, with plans to send an additional 1,584 to space by 2024 and 2,200 more by 2027.
Naturally, consumers have been wondering when they will be able to avail themselves of this new internet service. As SpaceX Chief Operations Officer Gwynne Shotwell announced on October 22nd, the company should be able to offer broadband access within the US by mid-2020. This came a day after Musk sent the inaugural tweet using Starlink services.
