SpaceX has raised $507 million, bringing the company's valuation to about $25 billion. That makes SpaceX the third most valuable venture-backed startup behind Uber and Airbnb, and also raises Elon Musk's worth by $1.4 billion to about $21.3 billion. SpaceX will launch NASA's TESS spacecraft on Monday, and plans to launch Bangabandhu-1 on May 5 using the Block 5 version of Falcon 9.
While SpaceX is planning to launch a record 30 missions in 2018, and possibly 50 missions in upcoming years, SpaceX expects the bulk of its future revenue to come from its upcoming Starlink satellite internet service. Internal documents show an estimate of $30 billion in revenue from Starlink and $5 billion from launches by 2025.
SpaceX President and Chief Operating Officer Gwynne Shotwell has said that the company's BFR could be used for 100-person city-to-city flights within a decade:
A lot can (and probably will) change in a decade. But the idea is that a very large rocket, capable of carrying about 100 people, could fly like an aircraft and do point-to-point travel on Earth much faster than a plane — halfway across the globe in about 30 to 40 minutes, Shotwell said, landing on a pad five to 10 kilometers outside of a city center. Shotwell estimated the ticket cost would be somewhere between economy and business class on a plane — so, likely in the thousands of dollars for transoceanic travel. "But you do it in an hour."
"I'm personally invested in this one," she said, "because I travel a lot, and I do not love to travel. And I would love to get to see my customers in Riyadh, leave in the morning and be back in time to make dinner."
How could travel by rocket cost so little? Shotwell said the efficiency would come from being fast enough to be able to operate a route a dozen or so times a day, whereas a long-haul airplane often only does one flight per day.
Finally, Elon Musk has showed off an image of the main body tool/manufacturing mold for the BFR. BFR has a height of 106 meters and diameter of 9 meters, compared to a height of 70 meters and diameter of 3.7 meters for Falcon 9.
SpaceX can start building its "Big Fucking Rocket," now that it has officially found a home in LA. Mayor Eric Garcetti has announced on Twitter that the private space giant "will start production development of the Big Falcon Rocket (the spacecraft's tamer name, apparently)" at the port of Los Angeles. SpaceX designed the 348-foot-long behemoth to fly humanity to the moon, Mars and beyond. It will be able to carry up to  tons in payload, whereas Falcon Heavy can only carry [63.8] tons. "This vehicle holds the promise of taking humanity deeper into the cosmos than ever before," he added, along with an illustration of the company's massive interplanetary spacecraft.
Finally, it's worth noting just how shockingly busy the BFR tent was on both April 13th and 14th, as well as the 8th (the first day Pauline visited the facility). With upwards of 40 cars parked at the tent, it's blindingly clear that SpaceX is not simply using the tent as a temporary storage location – alongside the arrival of composite fabrication materials (prepreg sheets, epoxy, etc) from Airtech International, SpaceX undeniably intends to begin initial fabrication of the first BFR prototypes in this tent, although they will likely eventually move the activities to the Berth 240 Mars rocket factory. That's certainly not a sentence I ever expected to write, but it is what it is.
The BFR's height may be elongated from its planned total of 106 meters.
Update 2: SpaceX's live coverage starts at 6:36 PM EDT (22:36 UTC).
Update 3: TESS successfully separated from Falcon 9 and was deployed into a highly elliptical orbit.
NASA's Transiting Exoplanet Survey Satellite (TESS) mission is set to launch
on April 16 at 6:32 PM ET (22:32 UTC) aboard a Falcon 9 rocket from SLC-40, Cape Canaveral Air Force Station, Florida. The spacecraft was developed by MIT with seed funding in Google back in 2008. The spacecraft will perform an all-sky survey using four 24° × 24° wide field-of-view cameras that can image a total of 24° × 96° (2,304 square degrees) of sky every 30 minutes (the Sun and Moon are only about 0.2 deg2 to Earth-based observers).
TESS will use a unique "P/2" 2:1 lunar resonant orbit to image stars in both the Northern and Southern hemispheres. The survey will image 26 observation sectors of 24° × 96° each, with some overlap at the ecliptic poles. The total survey area will be about 400 times larger than the area searched by the Kepler mission.
TESS will study about 500,000 stars, including the nearest 1,000 red dwarfs, with the goal of finding at least 3,000 new transiting exoplanet candidates. The spacecraft will study F, G, K and M type stars (spanning from F5 to M5), some of which are 30-100 times brighter than stars surveyed by the Kepler spacecraft. Many of the stars will be much closer to Earth than stars surveyed by Kepler, allowing for easier confirmation and follow-up measurements of exoplanets. 30-minute full-frame exposures will be used to search for transient events such as supernovae, star flares, and gamma-ray bursts.
Each observation sector will only be viewed for 27 days (at least in the initial phase of the mission), which will limit the exoplanets seen to those with shorter orbital periods. Potentially habitable exoplanet candidates will likely be found around red dwarfs rather than Sun-like stars. However, TESS's own orbit should remain stable for decades, which could mean that its mission will be extended to allow for a greater variety of exoplanets to be found.
The Los Angeles City Council on Tuesday approved a plan allowing SpaceX to build and operate a facility at the Port of L.A., where the Hawthorne space company will produce its next-generation BFR rockets and spacecraft.
The vote gives formal approval to a plan that got the greenlight last month from the L.A. Board of Harbor Commissioners.
During a presentation to the council, L.A. City Councilman Joe Buscaino said the project could result in up to 700 new jobs.
Under the terms of the deal, SpaceX will have an initial 10-year lease with two additional 10-year extension options. The company's initial rent will be $1.38 million a year, with annual adjustments based on the Consumer Price Index, but it can offset a total of $44.1 million in rent by making improvements to the Terminal Island site at Berth 240 in its first 20 years of tenancy.
Spotted on an official SpaceX T-shirt commemorating Starlink's first two prototype satellites and corroborated through analysis of limited public photos of the spacecraft, SpaceX appears to be testing a relatively unique style of solar arrays on the first two satellites launched into orbit, known as Tintin A (Alice) and B (Bob).
It's difficult to judge anything concrete from the nature of what may be immature prototypes, but SpaceX's decision to take a major step away from its own style of solar expertise – Cargo Dragon's traditional rigid panel arrays – is almost certainly motivated by a need to push beyond the current state of the art of satellite design and production.
Unlike any discernible solar panel deployment mechanism with a flight history, SpaceX's Starlink engineers seem to have taken a style of deployment used successfully on the International Space Station and mixed it with a modern style of solar arrays, relying on several flexible panels that can be efficiently packed together and designed to be extremely lightweight. While a major departure from SpaceX's successful Cargo Dragon solar arrays, the mechanisms visible on the Tintins seem to have the potential to improve upon the packing efficiency, ease of manufacturing, and number of failure modes present on Dragon's panels.
[...] To give an idea of where the industry currently stands, satellite internet provider Viasat launched its own Viasat-2 spacecraft in 2017. Weighing in around 6500 kg (14300 lb), the immense satellite cost at least $600 million and offers an instantaneous bandwidth of 300 gigabits per second, impressive but also gobsmackingly expensive at $2 million/Gbps. To ever hope to make Starlink a reality, SpaceX will need to beat that value by at least a factor of 5-10, producing Starlink satellites for no more than $1-3 million apiece ($4.5B-$13.5B alone to manufacture the initial 4,425 satellite constellation) with a bandwidth of 20 Gbps – baselined in official statements.
"Starlink is a satellite constellation development project underway by SpaceX, to develop a low-cost, high-performance satellite bus and requisite customer ground transceivers to implement a new space-based Internet communication system. By 2017, SpaceX had submitted regulatory filings to launch a total of nearly 12,000 satellites to orbit by the mid-2020s."
SpaceX CEO Elon Musk recently "fired at least seven" managers in order to speed up development and testing of satellites that could provide broadband around the world, Reuters reported today.
SpaceX denied parts of the story, saying that some of those managers left of their own accord and that the firings happened over a longer period of time than Reuters claimed.
[...] Among the fired employees were SpaceX VP of Satellites Rajeev Badyal and top designer Mark Krebs, Reuters wrote. "Rajeev wanted three more iterations of test satellites," Reuters quoted one of its sources as saying. "Elon thinks we can do the job with cheaper and simpler satellites, sooner."
Reuters described a culture clash between Musk and employees hired from Microsoft, "where workers were more accustomed to longer development schedules than Musk's famously short deadlines." Badyal is a former Microsoft employee, while Krebs previously worked for Google."
Apparently, the test satellites work:
"We're using the Tintins to explore that modification," one of the SpaceX employee sources said. "They're happy and healthy and we're talking with them every time they pass a ground station, dozens of times a day."
SpaceX engineers have used the two test satellites to play online video games at SpaceX headquarters in Hawthorne, California and the Redmond office, the source said. "We were streaming 4k YouTube and playing 'Counter-Strike: Global Offensive' from Hawthorne to Redmond in the first week," the person added.

SpaceX has asked the International Telecommunication Union to arrange spectrum for 30,000 additional Starlink satellites. SpaceX, which is already planning the world's largest low-Earth-orbit broadband constellation by far, filed paperwork in recent weeks for up to 30,000 additional Starlink satellites on top of the 12,000 already approved by the U.S. Federal Communications Commission.
The FCC, on SpaceX's behalf, submitted 20 filings to the ITU for 1,500 satellites apiece in various low Earth orbits, an ITU official confirmed Oct. 15 to SpaceNews.
[...] In its filings, SpaceX said the additional 30,000 satellites would operate in low Earth orbit at altitudes ranging from 328 kilometers to 580 kilometers.
[...] It is not guaranteed that, by submitting numerous filings, SpaceX will build and launch 30,000 more satellites. Tim Farrar, a telecom analyst critical of SpaceX, tweeted that he was doubtful the ITU will be able to review such big filings in a timely manner. He sees the 20 separate filings as a SpaceX effort to "drown the ITU in studies" while proceeding with its constellation.
