SpaceX worth $33B after raising more than $1B for Starlink and Starship

Since April 2018, SpaceX has successfully raised more than $1.24 billion through the sale of equity, likely sold to investors by extrapolating the company’s current record of success to include the potential of its next two products, Starlink and Starship.

Thanks to SpaceX’s successful streak of fundraising, the company is now valued at $33.3 billion according to sources that spoke with CNBC reporter Michael Sheetz. The same source indicated that demand for SpaceX equity remains strong as the company seeks to continue extremely expensive development and production programs. Most notably, SpaceX is simultaneously building two full-scale orbital Starship prototypes at separate facilities in Texas and Florida, readying an earlier Starhopper testbed for serious test flights, and is in the midst of ramping up its Starlink satellite production to levels unprecedented in the history of spaceflight.

Put simply, with SpaceX’s Starship and Starlink programs simultaneously entering into capital-intensive phases of development and production, the company has a huge amount of work on its plate. Most of that work involves testing prototypes with technologies that are frequently unprecedented, as well as refining those designs into something final and worthy of serious production. In the case of Starship, a great deal of integrated testing and design finalization lies ahead before SpaceX can even think about starting serial production of its ~50m (160 ft) tall steel Starships or ~60m (200 ft) Super Heavy boosters.

Although large-scale aerospace development programs already tend to be very expensive, SpaceX (led by CEO Elon Musk) has structured its Starship/Super Heavy development program to be extremely hardware-rich. This is another way to say that prototypes are constantly being built, designs are ever-changing, and hardware is constantly being severely damaged (or even destroyed) during fast-paced testing. SpaceX (and Musk) have often been famous for preferring development programs that move fast and break things, delivering knowledge and optimizing designs through lessons learned (often the hard way). SpaceX also values “scrappiness” in its programs, although that sadly ends up coming at the cost of employee pay (below industry standards) and benefits (scarce bonuses, no 401K-matching, extreme hours, minimal work-life balance).

Put it all together and the results of SpaceX-style development programs have frequently defied cemented industry expectations and beliefs. SpaceX has built – from scratch – entire launch vehicles (Falcon 9 V1.0) and spacecraft (Cargo Dragon) 5-10 times cheaper than NASA believed possible. SpaceX has successfully developed a commercially viable style of reusable rockets and took just ~30 months to go from its first attempted landing to a successful booster recovery and less than 15 months after that to reuse its first booster on a commercial, orbital-class launch. Competitors that vehemently denied that SpaceX would succeed are now 5-10 years behind with disinterested responses to the reusable titan that is Falcon 9/Falcon Heavy.

Still, while SpaceX’s record of commercial and technical spaceflight success is second-to-none since the Apollo Program and the early days of the Space Shuttle, even its extraordinarily cost-effective development style requires major funding in the face of ambitions as grand as Starship and Starlink.

The road to Mars… is an expensive one, no matter how you pave it.

Starlink races ahead

On May 23rd, SpaceX completed an extraordinarily ambitious Starlink launch debut, placing sixty “v0.9” spacecraft into low Earth orbit (LEO). Weighing no less than 16.5 tons (~36,000 lb), SpaceX’s first dedicated Starlink mission also became the heaviest payload the company has ever launched by at least ~30%. Aside from the spectacular statistics associated with the mission, SpaceX also debuted an exotic and largely unprecedented satellite form factor, stacking each flat, rectangular ~230 kg (510 lb) spacecraft like a deck of cards. With Starlink, SpaceX has also flown the first krypton-powered ion thrusters, replacing the traditional xenon to cut as much as $100,000 (or even more) from the cost of each satellite.

“We continue to track the progress of the Starlink satellites during early orbit operations. At this point, all 60 satellites have deployed their solar arrays successfully, generated positive power and communicated with our ground stations. Most are already using their onboard propulsion system to reach their operational altitude and have made initial contact using broadband phased array antennas. SpaceX continues to monitor the constellation for any satellites that may need to be safely deorbited. All the satellites have maneuvering capability and are programmed to avoid each other and other objects in orbit by a wide margin.” — SpaceX, May 31st

~20 days after launch, all 60 satellites are in contact with SpaceX ground controllers and all but 3-4 have managed to successfully begin raising their orbits from ~450 km to 550 km (280-340 mi). Roughly two dozen have already passed 500 km and most should reach their final orbits within 1-2 weeks.

By far the most significant news, however, was CEO Elon Musk’s confidence that SpaceX already has “sufficient capital to build an operational constellation”, likely referring to a constellation of 750-1500 spacecraft capable of either covering the entire US or offering “decent global coverage”. Of note, Musk made this comment days before SpaceX – via SEC filings – effectively announced that it has already raised more than $1B in 2019. A large portion – if not all – of that funding is thus likely bound for Starlink as the program’s shockingly small team of ~400 prepares to aggressively ramp up production.

According to both COO Gwynne Shotwell, Musk, and SpaceX, the company hopes to conduct an additional 1-5 launches of 60 Starlink satellites this year, potentially leaving SpaceX with a constellation of more than 400 satellites – with a total bandwidth of 7 terabits per second (tbps) – after just eight months of launches. Equally significant, SpaceX’s official Starlink.com website states that SpaceX wants to offer real internet service to an unspecified number of US and Canada consumers after just six launches. In other words, SpaceX could deliver the first (possibly alpha or beta) taste of consumer Starlink internet service by the end of 2019.

If SpaceX can deploy the constellation soon and Starlink reaches its cost, performance, and longevity targets, it’s safe to say that SpaceX’s private investors are going to be extraordinarily happy with their financial decision.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

on

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Published

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
