SpaceX is revolutionizing the Internet industry with its Starlink broadband satellite network. As of today, the company operates a constellation of around 4,265 Starlink satellites in Low Earth Orbit (LEO) that provide high-speed internet to over 1.5 million subscribers globally. SpaceX is launching Starlink satellites every month to continue expanding service coverage, with plans to launch a total of 12,000 satellites. Besides providing internet to homes and businesses, Starlink beams service directly to user antennas installed on vehicles in motion, like RVs, cruise ships, and aircraft.
In the early days of satellite internet, Geostationary Earth Orbit (GEO) satellites were the norm for aviation. These GEO satellites, positioned at an altitude of approximately 36,000 kilometers above the Earth’s surface, provided coverage to large regions but have limitations in terms of speed and latency – making it hard to livestream or have video calls in-flight. However, everything changed when SpaceX set its sights on LEO and launched thousands of satellites. One of the key advantages of Starlink’s satellites is the ability to provide faster internet speeds because they operate at much lower altitudes of around 550 kilometers. With traditional GEO satellites, the signal had to travel a considerable distance to reach the satellite and then make the round trip back to Earth, resulting in noticeable lag and latency average of around 600ms (milliseconds). In contrast, Starlink’s LEO satellites are positioned much closer to the planet, reducing the distance the signal travels.
The space firm, which has previously plucked a rocket booster out of the sky, will also launch NASA’s ‘swarm’ satellite, Starling.
Rocket Lab’s upcoming Electron mission, called “Baby Come Back”, will see the US and New Zealand-based company perform another marine recovery attempt of its rocket booster.
Rocket Lab announced in a press statement it will lift a number of satellites to low Earth orbit before attempting to retrieve its rocket booster from the ocean. The company is developing two reusability methods, one that plucks boosters out of the sky using a helicopter and the marine recovery method.
Optical data communications lasers can transmit several tens of terabits per second, despite a huge amount of disruptive air turbulence. ETH Zurich scientists and their European partners demonstrated this capacity with lasers between the mountain peak, Jungfraujoch, and the city of Bern in Switzerland. This will soon eliminate the necessity of expensive deep-sea cables.
The backbone of the internet is formed by a dense network of fiber-optic cables, each of which transports up to more than 100 terabits of data per second (1 terabit = 1012 digital 1/0 signals) between the network nodes. The connections between continents take place via deep sea networks—which is an enormous expense: a single cable across the Atlantic requires an investment of hundreds of millions of dollars. TeleGeography, a specialized consulting firm, announced that there currently are 530 active undersea cables—and that number is on the rise.
Soon, however, this expense may drop substantially. Scientists at ETH Zurich, working together with partners from the space industry, have demonstrated terabit optical data transmission through the air in a European Horizon 2020 project. In the future, this will enable much more cost‑effective and much faster backbone connections via near-earth satellite constellations. Their work is published in the journal Light: Science & Applications.
Join us on Wednesday, June 21 at noon Pacific for the DIY Picosatellites Hack Chat with Nathaniel Evry!
Building a satellite and putting it in orbit was until very recently something only a nation had the resources to accomplish, and even then only a select few. Oh sure, there were a few amateur satellites that somehow managed to get built on a shoestring budget and hitch a ride into space, and while their stories are deservedly the stuff of legends, satellite construction took a very long time to be democratized.
Fast forward a half-dozen or so decades, and things have changed dramatically. Satellite launches are still complex affairs — it’s still rocket science, after all — but the advent of the CubeSat format and the increased tempo of launches, both national and commercial, has pushed the barriers to private, low-budget launches way, way down. So much so, in fact, that the phrase “space startup” is no longer something to snicker about.
The SATRIA broadband relay station will boost internet connectivity across the vast Indonesian archipelago.
After Russian hackers destroyed Viasat satellite ground receivers spanning Europe, SpaceX provided coverage via Starlink, its Lower Earth Orbit satellite constellation, and soon began noticing cyberattacks and software interferences. Now, a year later, the U.S. Department of Defense announced Russia is still attempting to complicate connections within the satellite constellation and others like it.
Documents were leaked by U.S. National Guard airman Ryan Teixeira, as reported by The Washington Post back in April of 2023. Ukraine has also stated it is experiencing similar security issues.
“Russia’s quest to sabotage Ukrainian forces’ internet access by targeting the Starlink satellite operations that billionaire Elon Musk has provided to Kyiv since the war’s earliest days appear to be more advanced than previously known, according to a classified U.S. intelligence report.”
SpaceX’s Falcon 9 carrying the PSN Satria satellite successfully launched and deployed at 6:21 PM ET (22:21 UTC).
The launch had a 178-minute window, and upper-level winds delayed the first launch attempt at the opening of the window, but SpaceX had plenty of time to work with and launched just a bit later into the launch window.
The PSN Satria Indonesian Telecommunications was first contracted to be built in 2020 by Thales Alenia Spaceby the Indonesian government and delivered to the launch site in Cape Canaveral, Florida, in May 2023.
The transition to renewable energy, critical for the world’s future, is limited today by energy storage and transmission challenges. Beaming solar power from space is an elegant solution that […] promises a remarkable payoff for humanity: a world powered by uninterruptible renewable energy.
The California Institute of Technology reports the first successful beaming of solar energy from space down to a receiver on the ground, via the MAPLE instrument on its SSPD-1 spacecraft.

One California-based startup, Varda Space Industries, is betting that big business will lie in relatively unassuming satellites that will spend days or months in Earth’s orbit quietly carrying out pharmaceutical development. Its research, company officials hope, could lead to better, more effective drugs — and hefty profits.
“It’s not as sexy a human-interest story as tourism when it comes to commercialization of the cosmos,” said Will Bruey, Varda’s CEO and cofounder. “But the bet that we’re making at Varda is that manufacturing is actually the next big industry that gets commercialized.”
Varda is expected to launch its first test mission Monday aboard a SpaceX rocket. A window for take-off from Vandenberg Space Force Base in California begins at 2:19 p.m. PT.
