SpaceX’s second astronaut launch is a a step closer to flight after NASA and JAXA announced the third and fourth astronauts assigned to ride Crew Dragon to the International Space Station (ISS) on its first operational mission.

On the cusp of March 30th and 31st, the Japanese Space Agency (JAXA) made the first Crew Dragon-related announcement of the day, revealing the assignment of astronaut Soichi Noguchi to SpaceX’s Crew-1 launch. Hinging entirely on the success of SpaceX’s imminent Demo-2 astronaut launch debut, a critical demonstration mission scheduled to launch no earlier than mid-to-late May 2020, Crew Dragon’s Crew-1 mission will be the spacecraft’s first operational mission ferrying humans to and from the space station. NASA followed up JAXA’s announced hours later, revealing that astronaut Shannon Walker would be the fourth and final crew member aboard Crew Dragon’s Crew-1 launch.

Including Boeing’s Starliner and SpaceX’s Crew Dragon crewed demonstration missions, known as the Crewed Flight Test and Demonstration Mission 2 (Demo-2 or DM-2), respectively, NASA has purchased six astronaut launches from both providers. In theory, one Starliner and Crew Dragon launch per year – spaced out six or so months apart – should be enough to meet NASA’s space station transportation needs, meaning that the space agency’s 12 contracts should last until 2025 or 2026. Boeing’s Starliner appears to be delayed indefinitely after multiple near-catastrophic failures on its first Orbital Flight Test (OFT) but if SpaceX’s Demo-2 mission goes as planned, Crew Dragon could be set to enter operational duty as early as Q4 2020.

SpaceX’s Crew-1 mission manifest now includes NASA astronauts Mike Hopkins, Victor Glover, and Shannon Walker, as well as JAXA astronaut Soichi Noguchi and will likely carry an additional 100-200 kg (200-400 lb) of cargo to the International Space Station (ISS). While all eyes are reasonably on Crew Dragon’s Demo-2 mission, right now, the spacecraft’s Crew-1 through -5 missions are where SpaceX has the opportunity to gain extensive experience launching humans on an operational, semi-routine basis.

Making up at least half of the backbone of NASA’s new domestic astronaut launch capabilities, Crew Dragon and Falcon 9 will hopefully prove themselves to be as reliable and dependable as they and their predecessors have been over the years. Cargo Dragon, SpaceX’s first orbital-class spacecraft and the first private vehicle to visit the ISS, has successfully resupplied the space station and safely returned to Earth each of the 20 times the spacecraft reached orbit. Unsurprisingly, SpaceX ran into intermittent technical issues over those numerous flights, but all of those anomalies were solved on the fly and never prevented mission success or spacecraft recovery.

Falcon 9’s first in-flight failure destroyed the CRS-7 Cargo Dragon spacecraft in June 2015 and cut the mission short before it could reach orbit, but the failure was entirely unrelated to Dragon. Falcon 9’s second catastrophic failure occurred less than 15 months later, also a fault of a small but explosive rocket design flaw. From January 2017 to March 2020, however, Falcon 9 and Falcon Heavy rockets have completed 58 consecutively successful launches. With that streak of success, by certain measures, Falcon has become the most reliable operational rocket family in the world, tied with ULA’s famously reliable Atlas V and slightly better than Arianespace’s Ariane 5.

In short, while Cargo Dragon can’t hold a candle to the sheer scale of Russia’s Soyuz and Progress spacecraft flight histories, Falcon 9 is one of the two most reliable launch vehicles in operation and Crew Dragon will stand on the back of one of the most reliable spacecraft ever built in recent history. With (perhaps more than a little) luck, Boeing’s Starliner spacecraft – launched atop Atlas V, the other most reliable operational rocket – will hopefully be able to develop its own record of reliability in the next several years, but it will never be able to compete with the Cargo Dragon heritage Crew Dragon directly benefits from.

Boeing’s next Starliner mission is up in the air after the spacecraft’s almost disastrous orbital launch debut. Most likely, NASA will require a second uncrewed flight test, this time including the space station rendezvous, docking, and departure attempt Boeing had to cancel after Starliner’s major software failure. A second OFT would likely be ready for flight no earlier than Q3 or Q4 2020, depending on NASA’s investigation findings and requirements. If NASA remains confident and things go perfectly during the likely OFT2 mission, Starliner’s Crew Flight Test (CFT) could maybe launch by the end of 2020.

Crew Dragon’s Demo-2 astronaut launch debut is aiming for what NASA says is a mid-to-late May launch, although the mission is more likely to fly in the late-May to mid-June time frame. If Demo-2 launches on schedule (H1 2020) and is as flawless as Crew Dragon’s uncrewed Demo-1 launch debut, SpaceX could be ready to launch its second astronaut mission (Crew-1) as early as Q4 2020, possibly around the start of the quarter. With so much contingent on near-term reviews and tests, schedules beyond Demo-2 are unsurprisingly fluid.

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

Published

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.
