SpaceX’s Crew Dragon preps for debut as race to return astronauts to US craft nears final stages

Published

on

After spending two weeks testing in a specialized NASA-run facility, SpaceX’s first flightworthy Crew Dragon spacecraft was shipped from Ohio to Florida, where it will now spend a number of months preparing for its first (uncrewed) launch into Earth orbit.

Known as Demonstration Mission 1 (DM-1), this critical milestone must be passed before the capsule will be certified to carry NASA astronauts to the International Space Station (ISS) sometime in 2019. While DM-1 will not sport a human crew, the spacecraft is nevertheless expected to demonstrate all life and mission-critical components, ranging from Crew Dragon’s complex array of avionics and ground/orbital communications equipment to craft’s ability to safely return passengers to Earth with a soft ocean landing.

SpaceX’s Crew Dragon spacecraft has been in the serious hardware development phase for approximately five years, although the concept itself dates back about as early as its Cargo Dragon predecessor – 2005 to 2006, publicly. Over the course of roughly two weeks of testing at NASA’s Plum Brook Station, Crew Dragon was likely subjected to a suite of environmental conditions the spacecraft will need to routinely survive to make it through initial launch and successfully operate under the rigors of microgravity and thermal vacuum conditions.

Given the DM-1 capsule and trunk’s fairly quick jaunt at the huge Plum Brook vacuum chamber and equally quick arrival in Florida, those test results were likely quite favorable. Still, a major amount of work lies ahead before the first full Crew Dragon is ready for its launch atop Falcon 9. Most significantly, the craft’s trunk did not follow its fellow capsule to Florida, but rather returned to SpaceX’s Hawthorne, CA factory to be outfitted with critical flight hardware, particularly radiators and solar arrays. Once that outfit is complete, the module will also be shipped to Florida before being integrated with the DM-1 Crew Dragon capsule.

Of note, the DM-1 capsule has been constructed from the start to support a plan to use the vehicle in an in-flight abort test meant to ensure that the craft can wrest its passengers from harm’s way even at the most intense point of launch, where aerodynamic pressures are at their peak. In order to properly support both the DM-1 orbital mission and the in-flight abort test to follow, the capsule has been outfitted with a fair amount (hundreds of pounds) of hardware that will be unique to the pathfinder spacecraft. This understandably adds its own complexity to the already intense program’s first orbital mission, although it will hopefully not translate into additional delays.

SpaceX competitor’s crewed spacecraft and rocket take shape

It’s worth noting that SpaceX is effectively operating at a distinct – albeit partially self-wrought – financial handicap when compared with Boeing’s Starliner spacecraft program, one of two vehicles funded by NASA to accomplish the same task of safely and reliably transporting astronauts to and from the ISS.

“NASA awarded firm-fixed-price contracts in 2014 to Boeing and Space Exploration Technologies Corporation (SpaceX) [of] up to $4.2 billion [for Boeing] and $2.6 billion [for SpaceX] for the development of crew transportation systems.” (GAO-18-476)

 

In other words, Boeing requested and received a full 60% more than SpaceX to – quite literally – accomplish an identical task. Alongside the storied and brutally expensive history of crewed American spaceflight, both contracts are an absolute steal for two modernized, crew-capable spacecraft, but a 60% premium is a 60% premium. Foreseeable but slight cost overruns caused, among other things, by additional contractual requirements from NASA have followed a similar trend, roughly proportional to each company’s slice of the original $6.8b Commercial Crew contract.

“As of April 2018, NASA requirement changes had increased the value of contract line item 001 for Boeing by approximately $191 million and for SpaceX by approximately $91 million.” (GAO-18-476)

Still, Boeing’s progress towards its own DM-1 and DM-2 demo flights and a pad-abort test are impressive, although it very likely is more of a demonstration of a different approach to public communications than of any actual step up on SpaceX. In the last few weeks, Boeing has released a number of photos showing off the progress made building its own Starliner capsules and service modules (trunks), three of which are currently in varied states of assembly and integration in the company’s Florida-based facility. Additionally, United Launch Alliance CEO Tory Bruno has shared off-and-on updates and photos of the launch contractor’s own progress assembling the rockets that will launch Boeing’s spacecraft.

Regardless, a huge amount of work lies ahead before both Boeing and SpaceX’s crewed spacecraft are able to conduct their first uncrewed and crewed launches into orbit. Now very outdated, NASA has stated several times recently that the presently available targets of NET August 31 will likely be updated later this month, pushing DM-1 debuts into NET Q4 2018 and the first commercial crewed demo missions to 2019.

Stay tuned, as the Block 5 Falcon 9 tasked with launching SpaceX’s own DM-1 Crew Dragon will likely be the next of a recent flood of finished rockets to leave the company’s Hawthorne factory, where it will head to McGregor, Texas to complete acceptance wet dress rehearsals and static fire tests before shipping to SpaceX’s Pad 39A in Florida.

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.
