SpaceX’s partial Falcon 9 landing failure could delay next West Coast launch

Wait, that's not supposed to be there... (Tom Cross)

According to statements made by the Canadian Space Agency (CSA) and media outlet CBC, the launch of the agency’s next-generation Radarsat Constellation Mission (RCM) – a trio of Earth observation satellites weighing >4200 kg (9300 lbs) – has been “postponed … indefinitely” as a consequence of SpaceX’s first failed Falcon 9 booster landing since 2016.

Offering a rare glimpse into some of the extensive planning that goes on behind the scenes to make commercial rocket launches happen, CSA has indicated that the booster it planned to launch on – Falcon 9 B1050 – suffered an untimely (partial) demise during a recovery attempt shortly after successfully launching the CRS-16 Cargo Dragon mission on December 5th, 2018. While the booster shockingly was returned to dry land mostly intact after landing in the Atlantic, SpaceX and CSA must now settle on a different Falcon 9 to launch the mission.

Goldilocks and the Falcon boosters

While it doesn’t look like there are only three possible rocket options for the Radarsat constellation and SpaceX to choose from, the situation of picking a new booster this late in the launch flow is far less simple than it might initially seem. First and foremost, SpaceX likely needs to do its best to accommodate the preferences of customers CSA and MDA (MacDonald, Dettwiler and Associates Ltd.) regardless of how disruptive they may be. Originally targeted for sometime in November 2018, RCM’s launch slipped several months to the second half of February 2019 due to what CSA described as “higher priority missions [for]the US Government and a backlog of launches from…Vandenberg” late last year.

While that alone does not point directly towards any obvious explanations, CBC reporter Dean Beeby’s implication that the mission’s launch is now “postponed…indefinitely” offers a hint of an answer, although it could also be manufactured hyperbole where there actually is none. If CSA actually indicated that the launch is now postponed indefinitely, the only clear explanation for a launch delay greater than a month or so as a result of Falcon 9 B1050’s unplanned unavailability would lie in some unique aspect of that particular Falcon 9 booster.

Although each rocket SpaceX builds can be quite different from each other in terms of general quirks and bugs, the only obvious difference between B1050 and any other flight-proven Falcon 9 booster in SpaceX’s fleet was its low-energy CRS-16 trajectory, something that would have enabled a uniquely gentle reentry and landing shortly after launch. In other words, likely out of heaps of caution and conservatism if it is the case, customers CSA and MDA may have requested (or contractually demanded) that SpaceX launch the Radarsat constellation on a flight-proven Falcon 9 with as little wear and tear as possible, in which case B1050 would have been hard to beat.

“Unfortunately, the landing of [Falcon 9 B1050] was unsuccessful, preventing SpaceX from recuperating the reusable components for the launch of RCM. We continue to work closely with MDA and SpaceX to confirm a launch date for RCM.” – Spokesperson Audrey Barbier, Canadian Space Agency (CSA), 01/15/2019

If the customers remained steadfast in their (speculated) request for a gently-used flight-proven Falcon 9 even after B1050’s partial landing failure, the next most comparable booster would be Falcon 9 B1051 after launching the first orbital Crew Dragon mission sometime no earlier than (NET) February 2019. Aside from B1051, there will be no obvious booster alternative available for at least several months after Crew Dragon’s launch debut, unless NASA requests that its next contracted Cargo Dragon mission (CRS-17) launch on a new Falcon 9 rocket in March 2019.

Warmer…

If a less lightly-used booster becomes an option for CSA/MDA, there are immediately multiple clear options available as long as SpaceX is will to accept possible delays to subsequent launches to quickly reassign a flight-proven Falcon 9. Falcon 9 B1046 – the first SpaceX rocket ever to launch three orbital-class missions – is being refurbished at SpaceX’s Hawthorne, California facilities a few hundred miles south of Vandenberg. B1047 completed its second successful launch in November 2018 and is being refurbished – along with the twice-flown B1048 – in Cape Canaveral, Florida. Finally, Falcon 9 B1049 completed its second successful launch just days ago (January 11th) and is being processed off of drone ship Just Read The Instructions (JRTI) at this very moment.

B1047 or B1048 have likely been assigned to the imminent NET February 18th launch of Indonesian commsat PSN-6 and SpaceIL’s Beresheet Moon lander, meaning that the best possible option for Radarsat – short of swallowing months of additional delays – is a decision between B1047/B1048 or B1046, with B1049 also a candidate if a slip into March or April is an option. Still, all of those options would require Canada and MDA to fly on a Falcon 9’s third (or fourth) launch, perhaps an unacceptable compromise or perceived risk for certain customers.

 

Meanwhile, schedule pressures have meant that SpaceX is pushing as hard as possible to prepare three new Block 5 Falcon Heavy boosters for the giant rocket’s second and third launches, scheduled as early as March and April 2019. While unconfirmed, it appears that SpaceX may have chosen to manufacture all three of those boosters one after the other, meaning that the company’s Hawthorne factory would have been primarily focused on delivering those rockets for at least 2-3 months start to finish. In short, it does not appear that there is or will be an unflown Falcon 9 booster available for Radarsat anytime soon.

Whether the customers wait for a new booster to be produced, wait for Crew Dragon’s first launch to wrap up, or accept being the third or fourth launch of a well-scorched Falcon 9, RCM’s next published launch target should offer a hint as to how CSA, MDA, and SpaceX ultimately decided to respond to Falcon 9 B1050’s dip in the Atlantic OCean.

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

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.
