Despite a global pandemic and Falcon 9’s first in-flight engine failure in almost eight years, NASA administrator Jim Bridenstine remains confident that SpaceX and the space agency are still on track for Crew Dragon’s astronaut launch debut.

For the third time in about a month, NASA has officially confirmed that SpaceX’s Crew Dragon ‘Demo-2’ mission – the company’s first astronaut launch ever – is still tracking towards a liftoff in May 2020. While there are several good reasons to expect further delays, Bridenstine acknowledged and discounted those pressing risks in an April 9th interview with Spaceflight Now, explicitly stating that “if [Demo-2 does] slip, it’ll probably be into June. It won’t be much.”

Excluding several minor to moderate technical risks that have popped up in recent weeks, this suggests that the NASA administrator is also confident that one of the biggest sources of imminent schedule uncertainty – closed-door paperwork completion and joint reviews – will actually be smooth sailing.

On March 2nd, 2019, Falcon 9 lifted off for the first time with SpaceX’s upgraded Crew Dragon spacecraft on its inaugural orbital launch. Known as Demo-1, the mission was ultimately a flawless success, with Dragon performing exactly as expected throughout launch, orbit-raising, space station rendezvous, docking, departure, deorbit, reentry, and splashdown operations.

As Crew Dragon’s only orbital launch and space station docking, it also serves as the best and only glimpse into how long the more nebulous review and paperwork aspects of launch preparation can take. For Demo-1, Falcon 9 and Crew Dragon rolled out to Launch Pad 39A and completed a successful static fire on January 24th, 2019. The mission was then scheduled for launch no earlier than (NET) February 23rd and wound up being pushed back another week to March 2nd. In almost every case, Falcon 9 and Falcon Heavy launch less than a week after a successful preflight static fire and do not attempt a static fire until a given rocket and payload are both ready to go.

If there were technical challenges that lead to that six-week delay between Crew Dragon’s Demo-1 static fire and launch, they have never been broached publicly, making it more likely that NASA spent at least a month simply finishing up final paperwork and reviews. Hopefully, that substantial gap was mainly due to the fact that it was the first time NASA and SpaceX had to work together to launch Crew Dragon.

For Crew Dragon’s second Falcon 9 launch, successfully completed on January 19th, 2020, the rocket wrapped up its static fire test on January 11th — a major improvement compared to Demo-1. That suborbital In-Flight Abort (IFA) test isn’t directly comparable to Crew Dragon’s orbital launch debut, but it does encourage at least a little confidence that Demo-1’s six-week review period was an outlier.

Thankfully, Bridenstine says that all major Crew Dragon issues have been effectively closed out or are very close to closure as of April 2020. A SpaceX contractor was recently forced to prematurely drop a Crew Dragon parachute test vehicle on March 25th, destroying the mockup capsule before it could complete two final tests. The NASA administrator now says that all parties have agreed to complete those tests with a different mockup and will use a C-130 cargo plane instead of a helicopter.

By design, Crew Dragon Demo-2 astronauts Bob Behnken and Doug Hurley are likely about as insulated as one can get from the coronavirus pandemic. (SpaceX)

Bridenstine is also confident that the coronavirus pandemic – hampering almost all forms of industry in every afflicted country – will also have little to no impact on Crew Dragon’s astronaut launch debut schedule. NASA and SpaceX have put in place strict new rules and changed a number of procedures to further mitigate risk, helped by the fact that astronaut launches to the International Space Station (ISS) already operate with cleanliness and disease prevention as a major priority.

Finally, the NASA administrator also stated that SpaceX’s March 18th in-flight engine failure was “not going to impact our commercial crew launch,” confirming that SpaceX already has “a really good understanding of” what went wrong. Most likely, this means that Falcon 9 B1048’s stumble was directly related to the fact that the booster was flying for the fifth time – a first for a SpaceX rocket and orbital-class rocket boosters in general. Crew Dragon Demo-2 will be Falcon 9 booster B1058’s first launch.

Ultimately, while there are certainly good reasons to remain skeptical of NASA’s increasingly frequent assurances that Crew Dragon’s astronaut launch debut remains on track for late-May or June 2020, there are at least as many good reasons to stay confident.

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.
