SpaceX plans to start offering Starlink broadband services in 2020 - Oct 2019
"SpaceX president Gwynne Shotwell said the goal is to complete six to eight Starlink launches to get sufficient coverage to start offering the service to consumers in 2020."

"The company caused a stir last week when it requested the International Telecommunication Union to approve spectrum for 30,000 additional Starlink satellites to build the world’s largest low-Earth orbit broadband constellation. This was in addition to 12,000 already approved by the U.S. Federal Communications Commission. Shotwell said SpaceX is not certain that will need that many satellites. "

ESA spacecraft dodges potential collision with Starlink satellite - Sep 2019
"The European Space Agency said Sept. 2 it maneuvered one of its Earth science satellites to avoid a potential collision with a SpaceX Starlink satellite, the first time the agency said it’s had to maneuver to avoid a satellite associated with a broadband megaconstellation."

“The case just showed that, in the absence of traffic rules and communication protocols, collision avoidance has to rely on the pragmatism of the involved operators,” Krag said. “This is done today by exchange of emails. Such a process is not viable any longer with the increase of space traffic.”

"While ESA sounded worried about the close approach, others in the industry were nonplussed by the attention it received. "

LEO Survival of the Fittest…or the Smartest? - NSR
"Financial “fitness” can be thought of as the funding – either self or outside – that is essential for breaking the barriers to entry and for survival in the short-term. “Smartness” can be considered as the right target market, pricing strategy, capability and repeatability to ensure long-term sustainability. So, when it comes to LEO HTS Constellation survival, what is the answer to the question: Fit or smart?"

"A grand total of almost $48 B [in capex] must be invested to deploy all constellations as they are currently planned."

"From this assessment, based on the funding status and CAPEX to funding ratio, OneWeb is the “fittest” player today. That said, even though Amazon does not have any announced funding at this stage, NSR believes their deep pockets ensure that this will not be a challenge in the launch of Project Kuiper."

"... revenue estimates are a different game altogether. NSR forecasts $43.6B in overall Non-GEO revenues over the 2018 – 2028 period. "

"To compensate for higher than anticipated expenses during the early stages, OneWeb has shifted their short -term priority towards higher revenue generating applications. "

"As one of the biggest constellations planned, SpaceX’s constellation is also associated with the highest expenses. With over $1B in funding raised so far, it makes up a mere 7% of the total estimated CAPEX. ... Starlink’s architecture does allow SpaceX to offer high speed Internet to markets with high price tolerance. But will the market size be big enough to support SpaceX’s long-term plans?"

"The latest news from Telesat indicates it will hedge its bets with a hybrid architecture."

"Short-term “fitness” remains the biggest question for LeoSat as they work towards lowering the overall system CAPEX."

Might Satellite Constellations Learn to Avoid Debris? Larry Press, May 2019
The ESA estimates that there have been over 500 break-ups, explosions, collisions, or anomalous events resulting in fragmentation and they estimate that there are 34,000 debris objects >10 cm, 900,000 from 1 to 10 cm and 128 million from 1 mm to 1 cm. NASA says there are there are more than 20,000 pieces of debris larger than a softball, 500,000 the size of a marble or larger many millions so small they can't be tracked.

Here Are the Odds That One of SpaceX’s Internet Satellites Will Hit Someone - IEEE Spectrum Dec 2018
"The chance that SpaceX’s planned Starlink satellite constellation will cause an injury or death is 45 percent every six years, according to an IEEE Spectrum analysis of figures submitted by the company to the U.S. Federal Communications Commission."

"When that fuel runs low, after around six years, the satellites will use the remainder to nudge themselves into the denser atmosphere below. Each satellite, just a little smaller in size than a Tesla Model 3, will then swiftly burn up. Except that some of it won’t. "

"When SpaceX plugged the numbers into NASA’s Debris Assessment Software, the package calculated that there was, at most, a 1 in 18,200 chance that an individual satellite in its LEO orbital shells would hurt or kill someone. VLEO satellites were generally slightly riskier, with up to a 1 in 17,400 chance. All figures are handily less than the 1 in 10,000 figure that NASA has adopted as a standard, and that U.S. and European space agencies require for space missions."

SpaceX proposes lower orbit for its 4,000+ satellite constellation | FierceWireless Nov 2018
"SpaceX is asking the FCC to approve modifications to its license to launch and operate a constellation of non-geostationary (NGSO) satellites, reducing the altitude from 1,150 kilometers to a new altitude of 550 km.

The change in altitude will result in lower latency for the satellites—as well as allow SpaceX to speed up the deployment of its constellation."

"The revised plan calls for 16 fewer satellites—to 4,409. It would also allow for SpaceX to surpass the deployment milestones laid out in its license. Under commission rules, it’s supposed to begin operation of at least half of its authorized satellites no later than March 29, 2024. But the new target calls for launching its first batch of satellites before the end of 2019."

"The company explained that by operating closer to the Earth, SpaceX would be able to reduce the latency of its communications signals to as low as 15 milliseconds, “at which point it would be virtually unnoticeable to almost all users.” Under the previous altitude plan, the latency was expected to be on the order of 25-35 milliseconds."

"Moving to the lower altitude also increases the space between its satellites and those of other large proposed NGSO constellations, including OneWeb, Boeing and Telesat."

Musk shakes up SpaceX in race to make satellite launch window: sources | Reuters Oct 2018
"Within hours of landing [in June 2018], Musk had fired at least seven members of the program’s senior management team at the Redmond, Washington, office, the culmination of disagreements over the pace at which the team was developing and testing its Starlink satellites, according to the two SpaceX employees with direct knowledge of the situation. "

"But the program is struggling to hire and retain staff, the employees said"

"Among the managers fired from the Redmond office was SpaceX Vice President of Satellites Rajeev Badyal, an engineering and hardware veteran of Microsoft Corp and Hewlett-Packard, and top designer Mark Krebs, who worked in Google’s satellite and aircraft division, the employees said."

"The management shakeup followed in-fighting over pressure from Musk to speed up satellite testing schedules, one of the sources said."

Satellite Constellations: Too Much of a Good Thing? - Northern Sky Research, Aug 2018
"LEO constellations, theoretically, benefit from economies of scale [but] it is crucial to recognize the point where the variable costs start to outweigh the fixed cost benefits, and the cost save turns into cost disadvantages, also known as diseconomies of scale."

"To support the production of satellite constellations ... will most definitely result in bottlenecks within the industry with further increase in internal diseconomies of scale for operators as well as for the suppliers."

"At a certain point, the additional satellites for the larger constellation continue to increase the costs but are unable to produce revenues at the same rate, resulting in a lower ROI for the 4,425-satellite [SpaceX] constellation."

How Much Does It Cost to Launch a Satellite? Motley Fool June 2016
"ULA says that a "lower-end mission," carrying perhaps 4.75 metric tons aboard one of its Atlas V rockets costs $164 million, while launch costs across its entire fleet average $225 million. (Maximum payload: 8.9 tons.)"
"Ariane 62, designed to launch 5-ton scientific satellites into GTO, is targeting a launch cost of $77 million. Ariane 64, a heavy-lift rocket capable of hoisting two 5-ton satellites into space simultaneously, similar to Boeing's plan, would cost $126 million per launch -- or just $63 million per satellite delivered."

NOAA explains restriction on SpaceX launch webcast - Apr 2018
"During the March 30 launch of 10 Iridium Next satellites on a SpaceX Falcon 9, SpaceX cut off the live video from the rocket’s second stage nine minutes after liftoff. The company cited “restrictions” imposed by the National Oceanic and Atmospheric Administration for terminating the live feed."

"In a statement later March 30, NOAA invoked federal law that requires any commercial remote sensing system capable of taking images of the Earth from orbit be licensed by the agency. “Now that launch companies are putting video cameras on stage 2 rockets that reach an on-orbit status, all such launches will be held to the requirements of the law and its conditions,” NOAA stated. "

"For now, NOAA does not have the ability to waive the need for a license, including for upper stages with onboard cameras."

"accepted SpaceX’s application to reach U.S customers with a megaconstellation of 4,425 broadband satellites, but denied the company’s request to relax the deadline by which it must have its entire constellation in orbit. [FCC] also said SpaceX’s approval is conditioned on an updated de-orbit plan, since the sheer number of satellites envisioned by SpaceX’s “Starlink” constellation goes far beyond what current guidelines consider manageable."

"NASA, which said a constellation as large as SpaceX’s likely needs to meet more stringent standards than what NASA recommends for de-orbit reliability. NASA’s reliability standard is that at least 90 percent of satellites can deorbit properly after their mission is complete."

Air Force stakes future on privately funded launch vehicles. Will the gamble pay off? - Mar 2018
"The schedule is getting tight for the U.S. Air Force as a 2022 deadline looms to bid farewell to the Atlas 5 and switch to a different rocket that is not powered by a Russian engine."

"... to find alternatives to the United Launch Alliance’s Atlas 5 that uses the Russian RD-180 engine"

"The Air Force signed cost-sharing partnerships with ULA, SpaceX, Orbital ATK and Aerojet Rocketdyne. ... The next step is to select three companies this summer to move forward with enginet [sic] prototypes."

"The selected competitors will face a schedule that seems ambitious even by the standards of commercial space companies."

"A contrarian view comes from the defense industry establishment. Loren Thompson, of the Lexington Institute — a think tank that receives funding from ULA owners Boeing and Lockheed Martin, Aerojet and other defense firms — has called on the Air Force to keep the Atlas 5 and swap the RD-180 engine for Aerojet Rocketdyne’s AR-1 rather than develop a new launch vehicle."

Firing It Up at Both Ends? New Launch Vehicles Extend Mass Range - Via Satellite - Mar 2018
"Falcon Heavy has nearly doubled the launch range from a former 14.2 tons to Geostationary Transfer Orbit (GTO), via Delta 4 Heavy, to a whopping 26.7 tons. It has also globalized SpaceX’s addressable market, previously limited to Falcon 9’s capability of 8.3 tons to GTO (and a much smaller 4.5 tons when Falcon Heavy was first announced). Turning to the market’s other new entrant, Rocket Lab’s Electron launch vehicle addresses payloads with a nominal mass of 150 kg and up to 225 kg, reducing the lower limit of the orbital class market by several hundred kilograms."

"With a market Northern Sky Research (NSR) expects to double in the next five years, and a trend of increasing mass from sub-10 kg cubesats to 50 kg-plus microsatellites, Electron’s relevance to the market is evident.

The significance of extended heavy-lift capacity to the market is less clear. "

"Headwinds in the commercial GEO market have gutted demand for manufacturing and launch, with operators striving more than ever for capital expenditure efficiency via delayed procurements and cost-saving designs. Rates of adoption of electric propulsion and digital payloads have surged, reducing average satellite mass. Current demand is thus well addressed by existing launch services, with even new appeal of dual launches on Proton and triple launches on Ariane 5 to further reduce capex with mid-sized GEOs."

SpaceX Indicates Satellite-Based Internet System Will Take Longer Than Anticipated - WSJ Feb 2018
“Acknowledging there are no final cost estimates or engineering designs yet for its proposed broadband constellation, spokesman John Taylor revealed substantial delays from initial project timelines. In a statement provided exclusively to The Wall Street Journal on Tuesday night, billionaire Elon Musk's company signaled that development of its high-profile satellite network has been significantly slower -- and seemingly more complex -- than many inside and outside SpaceX originally anticipated.”

“SpaceX said in Tuesday night's statement, "we still have considerable technical work ahead of us to design and deploy" some 4,400 similar satellites. The tentative goal of starting limited service by 2020 now appears unrealistic based on that language, but the company didn't provide an alternate schedule.”

“SpaceX engineers are still considering the most appropriate and cost-effective space and ground technologies to embrace, without firming up subcontractors or completing production plans.”

“… technical and financial details of anticipated ground equipment for subscribers -- considered critical elements in any such project -- are still undetermined.”

" SpaceX said its BFR rocket – ostensibly for Mars and moon missions – could provide anywhere-on-Earth, city-to-city transport in under an hour. And Virgin Galactic, focused on suborbital tourist trips with its rocket plane, also has city-to-city travel on its radar. So a supersonic future is a done deal? One barrier to a spaceplane route is that the US may deem landing a rocket abroad as breaching a ban on exporting this technology."

5 Developments in NewSpace for 2018 - Nanalyze Jan 2018
"In our teardown on NewSpace exploding into a trillion-dollar industry, we noted that the satellite sector, which includes everything from manufacturing spacecraft to providing communications services, represents about 75 percent of the total commercial space industry. The industry is valued at about $350 billion today. There’s no reason to doubt that ratio will change in 2018."

"More recent deals include a $3.2 million Seed round to Loft Orbital out of San Francisco in November. The startup, founded only this year, leases space on its satellites for various Earth-observing missions. It even handles the red tape on issues such as licensing and insurance. Another relatively new NewSpace startup, Analytical Space, took in $3.5 million in September for its satellite relay system that uses laser technology to beam data in orbit back to Earth cheaper and faster."

"Seraphim Space Fund recently launched a $100 million initiative and Starburst Ventures, part of Starburst Accelerator, raised a $200 million fund to invest in 35 space startups over the next three years. Meanwhile, the Space Startup Ecosystem plans to help launch 100 NewSpace companies each year. Let’s put that into perspective: Only about 140 angel- and venture-backed space companies have been founded and funded since 2000, according to Bryce Space & Technology, an analytic consulting firm."

Six New Entrants to the Satellite Industry in 2017 - Via Satellite - Dec 2017
"Despite tough margins across the market, 2017 marked a number of significant milestones for the global space industry. In March, SpaceX successfully launched and relanded a flight-proven, first-stage booster for the first time; in February, the Indian Space Research Organization’s (ISRO) PSLV broke a record for the most satellites launched simultaneously at 104; and in June, Arianespace launched the heaviest payload in history into Geosynchronous Transfer Orbit (GTO), lofting the combined weight (21,977 pounds) of ViaSat 2 and Eutelsat 172B.

But 2017 was pockmarked by smaller victories too. A number of countries and universities that previously had lackluster or nonexistent space programs have taken big risks to place some of their first satellites into orbit. Here’s a rundown of the newest entrants to the satellite industry this year, as well as other players who have announced their plans to orbit an asset in the near future."

"Japan and Ghana formed an unlikely partnership this year to help orbit the African nation’s first ever satellite, an optical remote sensing CubeSat called GhanaSat 1."

"In November, Arianespace launched Mohammed 6A for Morocco — a high-resolution surveillance satellite that Moroccan officials claim will only be used for civilian purposes. Nonetheless, according to news agency France 24, Morocco’s neighbors are concerned about the satellite’s potential military applications."

SpaceX Testifies: First Prototype Satellite Coming This Year - Via Satellite - Nov 2017
"In an Oct. 25 testimony delivered to the Senate Committee on Commerce, Science, and Transportation, SpaceX Vice President of Satellite Government Affairs Patricia Cooper reaffirmed the company’s plans to launch the first prototype of its Low Earth Orbit (LEO) broadband constellation before the end of the year and an additional prototype in the early months of 2018.

Cooper also stated that SpaceX expects to begin offering commercial services with as few as 800 satellites on orbit. When fully deployed, the constellation — dubbed “Starlink,” as a recent trademark filing revealed — will comprise 4,425 Ku- and Ka-band satellites operating in 83 planes. In her testimony, Cooper referred to an additional constellation of 7,500 V-band satellites that will fly even closer to Earth than the Starlink system, in Very Low Earth Orbit (VLEO)."

"Cooper also highlighted SpaceX’s belief that systems with more efficient spectrum use should be “rewarded.” According to her testimony, operators investing in more advanced technologies should not be forced to carry an asymmetrical burden when it comes to spectrum sharing. “The Committee should ensure that their rules do not unduly burden more flexible, adaptable systems with the responsibility of spectrum sharing with other less sophisticated systems,” she said."

"Asked about the major factors affecting investment in next-generation satellite technology, several leading satellite players said access to spectrum is the No. 1 issue. Executives from ViaSat, Intelsat and OneWeb testified Wednesday during a U.S. Senate Committee on Commerce, Science and Transportation hearing"

"Another related area: unlicensed spectrum. The business model changes dramatically when unlicensed spectrum is made available. In Africa, ViaSat needs to go through cellular operators to provide service, but the cell equipment costs thousands of dollars. In Mexico, it’s able to go directly with its own satellites and put in a Wi-Fi hotspot for $1,000, so seeing regulations to support those kinds of models would be very helpful, Dankberg said."

"As more satellites are launched, the potential for collisions rises, and OneWeb’s Wyler stressed that a more formal process needs to be created to prevent catastrophe in space."

Satellite constellations could be poised to challenge the broadband industry - LA Times, Dec 2016
"Now, a new generation of satellite entrepreneurs is headed back to the launch pad. Backed by billions of dollars from deep-pocketed investors, they plan to blanket the earth in the next few years with perhaps thousands of miniature satellites beaming cheap, ubiquitous broadband service. What’s different? Launching one of these smaller satellites can cost a fraction of the price for a larger, school-bus-sized satellite. These new satellites will largely be mass-produced. And consumers now demand high-speed Internet connectivity pretty much everywhere, on airplanes, cruise ships and in the remotest village in Africa. "

"By 2022, OneWeb says it will connect every unconnected school to the Internet. Eventually, OneWeb plans a 700-satellite constellation. OneWeb’s satellite manufacturing facility in Exploration Park, Fla. is key to these plans."

"Hawthorne-based SpaceX plans to eventually launch more than 4,000 satellites for its network. Each satellite would be about 13 feet long and 6 feet wide, with 19-foot-long solar arrays."

FCC gets five new applications for non-geostationary satellite constellations - March 2017
Boeing: “1,396 to 2,956 low-Earth orbit (LEO) satellites for providing connectivity”

SpaceX: VLEO, “V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band”

Telesat: “V-band LEO constellation as one that “will follow closely the design of the Ka-band LEO Constellation,” also using 117 satellites (not counting spares) as a second-generation overlay.”

Theia: “use V-band frequencies for gateways on the ground that would have originally only used Ka-band. The company wants to operate a constellation of satellites for both communications and remote sensing, and claims that because its spacecraft will have “regenerative” payloads, that “there is no specific relationship between V-band uplink frequency bands and downlink frequency bands.””

OneWeb: “operate a “sub-constellation” of 720 LEO V-band satellites at 1,200 kilometers, and another constellation in Medium Earth Orbit (MEO) of 1,280 satellites. Added together, that expands the OneWeb constellation by 2,000 satellites”

"For the NYU astronomy students, Mueller described how SpaceX is tackling every ounce of weight on its launchers, building in-house whenever possible to avoid vendors trained in the government’s oversight-heavy procurement process, and working toward a methane-fueled launch vehicle because methane is cheap, and it can be generated on the red planet that Musk hopes to colonize in his lifetime. Mainly, though, the company is working toward total reusability to cut the cost of launch. "

"Boeing last week filed an application with the FCC to launch and operate a geo-stationary satellite orbit (NGSO) fixed satellite service (FSS) system operating in low Earth orbit (LEO) in the 37.5-42.5 GHz, 47.2-50.2 and 50.4-52.4 GHz bands, collectively known as the V-Band. In so doing, it's putting its hat into the same ring as companies like SpaceX and OneWeb."
"Boeing's application said its NGSO system would consist of a total constellation of 2,956 NGSO FSS satellite to provide very high speed, low latency internet connectivity for user terminals via the system's network access gateways and associated terrestrial fiber network. "

"Musk needs a thumbs-up from the US Federal Communications Commission to put his satellites into orbit. But on July 9, Intelsat wrote a letter to the FCC asking that the agency block Musk's application for an experimental license, on grounds that the SpaceX founder is being too secretive about his plans."
