Starlink, SpaceX’s internet connectivity satellite constellation, is taking form. The project is designed to offer higher speeds and lower latency than competing setups, so long as the receiver can see the satellites in orbit. It could help fund some of CEO Elon Musk’s more ambitious goals, like a city on Mars and a planet-hopping society.
But although SpaceX has launched three batches of 60 satellites already, ahead of a planned start for services later this year, how to connect to Starlink remains difficult to understand. How much will a subscription cost? Will it be available in my area? Is Starlink going to keep interrupting astronomers’ work? This week, Musk provided new details about Starlink’s features.
SpaceX has ambitious plans for Starlink. It’s requested permission to launch up to 42,000 satellites, a huge number considering there’s around 5,000 satellites in space total. Each craft orbits at 550 kilometers above sea level, much lower than most satellites.
The first 60 Starlink satellites just moments before they were deployed.
It could mean big money for SpaceX. Musk told reporters in May 2019 that internet is a $1 trillion market. Capturing around five percent of that would give SpaceX around $50 billion per year. That would greatly eclipse the satellite industry, which only brings in around $5 billion per year in its entirety, and could go some way to meeting the cost of a city on Mars that could run up to $10 trillion.
Here’s how it may work.
SpaceX Starlink: how to connect to the internet service
Based on previously released information, Starlink will not interface directly with devices. In other words, your laptop won’t connect directly to the sky satellites.
Starlink will provide access through a ground terminal. On January 7, Musk said that the terminal “looks like a thin, flat, round UFO on a stick.” It’s also equipped with “motors to self-adjust optimal angle to view sky.”
This chimes with SpaceX’s FCC fling in October 2018, which described the ground terminal as about the same size as a pizza box. SpaceX’s 2016 filing describes it as a “low-profile user terminal that is easy to mount and operate on walls or roofs.”
In his January 2020 post, Musk even produced a series of easy-to-follow instructions:
Instructions are simply:
– Plug in socket
– Point at sky
These instructions work in either order. No training required.

If Apple taught the world anything, it’s that people love getting online in just two steps:
The service may have already had its first user — Musk claimed in October 2019 that he sent a post via the service to Twitter.
Musk’s tweet flies through the air.
SpaceX Starlink: when will it be available?
SpaceX’s website currently claims that service will be provided for the northern United States and Canada as early as 2020. This will expand to “near global coverage of the populated world” by 2021.
The company has completed three launches, each packing 60 production-design satellites. The first was launched in May 2019, the second in November 2019, and the third in January 2020.
Musk claimed ahead of the May 2019 launch that six more launches would be needed to provide minor coverage, and 12 more launches would offer moderate coverage. An earlier version of Starlink’s website claimed that services in the northern United States and Canada would start after six launches, with global coverage of the populated world after 24 launches. This claim has now been removed from the Starlink website.
SpaceX Starlink: how much will it cost per month?
This is the big unknown. SpaceX president Gwynne Shotwell said in October 2019 that many consumers are paying $80 for “crappy service.” Shotwell did not, however, confirm the price during this appearance.
During a 2015 speech in Seattle, Musk shot down the idea of offering the service for free. He also suggested a price for the terminal at somewhere between $100 and $300.
The Starlink mission takes off.
SpaceX Starlink: what will be the specifications for speed and latency?
This is another question that may become clearer with real-world tests. The company’s 2016 filing with the FCC described internet service up to one gigabit per second, and latencies between 25 and 35 milliseconds.
More recently, SpaceX has been working with the United States Air Force to offer internet service. The program started tests in early 2018, using the two prototype satellites to reach speeds of up to 610 megabits per second.
SpaceX Starlink: how to sign up for reservations
SpaceX’s website does not offer anywhere to place contact information for more details, but watch this space — Tesla’s Model 3 reservation program proved wildly popular in 2016, with lines forming around blocks to place $1,000 down for the entry-level electric car.
TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.
Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.
Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.
The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.
The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.
It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.
Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.
Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.
Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.
Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.
Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.
The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.
Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”
Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.
“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.
B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.
Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.
Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.
Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.
“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”
Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”
“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.
Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.
“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
This report by The Canadian Press was first published Sept. 9, 2024.
The European Space Agency is fast-tracking a new mission called Ramses, which will fly to near-Earth asteroid 99942 Apophis and join the space rock in 2029 when it comes very close to our planet — closer even than the region where geosynchronous satellites sit.
Ramses is short for Rapid Apophis Mission for Space Safety and, as its name suggests, is the next phase in humanity’s efforts to learn more about near-Earth asteroids (NEOs) and how we might deflect them should one ever be discovered on a collision course with planet Earth.
In order to launch in time to rendezvous with Apophis in February 2029, scientists at the European Space Agency have been given permission to start planning Ramses even before the multinational space agency officially adopts the mission. The sanctioning and appropriation of funding for the Ramses mission will hopefully take place at ESA’s Ministerial Council meeting (involving representatives from each of ESA’s member states) in November of 2025. To arrive at Apophis in February 2029, launch would have to take place in April 2028, the agency says.
This is a big deal because large asteroids don’t come this close to Earth very often. It is thus scientifically precious that, on April 13, 2029, Apophis will pass within 19,794 miles (31,860 kilometers) of Earth. For comparison, geosynchronous orbit is 22,236 miles (35,786 km) above Earth’s surface. Such close fly-bys by asteroids hundreds of meters across (Apophis is about 1,230 feet, or 375 meters, across) only occur on average once every 5,000 to 10,000 years. Miss this one, and we’ve got a long time to wait for the next.
When Apophis was discovered in 2004, it was for a short time the most dangerous asteroid known, being classified as having the potential to impact with Earth possibly in 2029, 2036, or 2068. Should an asteroid of its size strike Earth, it could gouge out a crater several kilometers across and devastate a country with shock waves, flash heating and earth tremors. If it crashed down in the ocean, it could send a towering tsunami to devastate coastlines in multiple countries.
Over time, as our knowledge of Apophis’ orbit became more refined, however, the risk of impact greatly went down. Radar observations of the asteroid in March of 2021 reduced the uncertainty in Apophis’ orbit from hundreds of kilometers to just a few kilometers, finally removing any lingering worries about an impact — at least for the next 100 years. (Beyond 100 years, asteroid orbits can become too unpredictable to plot with any accuracy, but there’s currently no suggestion that an impact will occur after 100 years.) So, Earth is expected to be perfectly safe in 2029 when Apophis comes through. Still, scientists want to see how Apophis responds by coming so close to Earth and entering our planet’s gravitational field.

“There is still so much we have yet to learn about asteroids but, until now, we have had to travel deep into the solar system to study them and perform experiments ourselves to interact with their surface,” said Patrick Michel, who is the Director of Research at CNRS at Observatoire de la Côte d’Azur in Nice, France, in a statement. “Nature is bringing one to us and conducting the experiment itself. All we need to do is watch as Apophis is stretched and squeezed by strong tidal forces that may trigger landslides and other disturbances and reveal new material from beneath the surface.”

By arriving at Apophis before the asteroid’s close encounter with Earth, and sticking with it throughout the flyby and beyond, Ramses will be in prime position to conduct before-and-after surveys to see how Apophis reacts to Earth. By looking for disturbances Earth’s gravitational tidal forces trigger on the asteroid’s surface, Ramses will be able to learn about Apophis’ internal structure, density, porosity and composition, all of which are characteristics that we would need to first understand before considering how best to deflect a similar asteroid were one ever found to be on a collision course with our world.
Besides assisting in protecting Earth, learning about Apophis will give scientists further insights into how similar asteroids formed in the early solar system, and, in the process, how planets (including Earth) formed out of the same material.
One way we already know Earth will affect Apophis is by changing its orbit. Currently, Apophis is categorized as an Aten-type asteroid, which is what we call the class of near-Earth objects that have a shorter orbit around the sun than Earth does. Apophis currently gets as far as 0.92 astronomical units (137.6 million km, or 85.5 million miles) from the sun. However, our planet will give Apophis a gravitational nudge that will enlarge its orbit to 1.1 astronomical units (164.6 million km, or 102 million miles), such that its orbital period becomes longer than Earth’s.
It will then be classed as an Apollo-type asteroid.
Ramses won’t be alone in tracking Apophis. NASA has repurposed their OSIRIS-REx mission, which returned a sample from another near-Earth asteroid, 101955 Bennu, in 2023. However, the spacecraft, renamed OSIRIS-APEX (Apophis Explorer), won’t arrive at the asteroid until April 23, 2029, ten days after the close encounter with Earth. OSIRIS-APEX will initially perform a flyby of Apophis at a distance of about 2,500 miles (4,000 km) from the object, then return in June that year to settle into orbit around Apophis for an 18-month mission.

Furthermore, the European Space Agency still plans on launching its Hera spacecraft in October 2024 to follow-up on the DART mission to the double asteroid Didymos and Dimorphos. DART impacted the latter in a test of kinetic impactor capabilities for potentially changing a hazardous asteroid’s orbit around our planet. Hera will survey the binary asteroid system and observe the crater made by DART’s sacrifice to gain a better understanding of Dimorphos’ structure and composition post-impact, so that we can place the results in context.
The more near-Earth asteroids like Dimorphos and Apophis that we study, the greater that context becomes. Perhaps, one day, the understanding that we have gained from these missions will indeed save our planet.
