SpaceX talks Moon mission as strategic stepping stone for Mars colony

Published

on

Josh Brost, Senior Director of SpaceX’s Government Business Development was in attendance at a civil spaceflight conference in Washington D.C. yesterday, January 18, and provided a number of interesting details about SpaceX’s upcoming activities in 2018. Perhaps most intriguingly, he reiterated SpaceX’s interest in enabling exploration of the Moon and Mars, while also clarifying that the upcoming Falcon 9 upgrade will be the last major change to the vehicle for the indefinite future.

Although the audience may have been more focused on SpaceX’s potential lunar prospects, Brost provided a vision similar to CEO Elon Musk’s common-knowledge goal of Martian (and interplanetary) colonization. This lunar focus was in part evidenced by a pointed question from an audience member that triggered Brost’s subsequent suggestion that the Moon could be a more logical starting place for the company as it ramps up its deep space efforts and gradually slips beyond Earth orbit. This strategic and calculated extension of the aspirations of the launch company’s famous founder is a rational attempt to position SpaceX in ways that allow the company to derive as much value as possible from the US government’s recently revived interest in returning the US and its astronauts to the Moon.

To a large extent, his comments mesh with the vision Elon Musk reiterated at 2017’s September IAC.

SpaceX’s next-generation heavy-lift rocket and spaceship (BFR and BFS) are being designed to carry 150 metric tons into low Earth orbit while still recovering both the first and second stages, and will be purpose-built for rapid and complete reusability. BFR and BFS are also being intentionally designed to be relatively destination-agnostic. In other words, BFS will be capable of transporting cargo and eventually crew to a number of destinations in the solar system, be it the Moon, Mars, or beyond. The outer planets are almost certainly off limits for crew due to the sheer length of any journey beyond the orbit of Mars, but BFR, as it was discussed last year, would be capable of transporting unprecedented amounts of cargo almost anywhere in the solar system. Reusability is, of course, paramount to SpaceX’s operational intent with BFR/BFS; unless a very lucrative offer is made, it is highly unlikely that SpaceX will even consider expendable missions, thus partially limiting what the next-gen vehicle will be capable of.

Still, it will be an incredibly capable rocket even with full reusability. Add in the potential promise of mature in-situ resource utilization (ISRU), more simply the production of methane and oxygen propellant at the destination, and it will open a hundred entirely new worlds to serious scientific, exploratory, and economic prospecting throughout the solar system.

What’s next?

The question, then, is “when?” While Brost did not specifically provide any sort of timeline for BFR, aside from a brief statement on its readiness in “a few years,” he did describe in some detail the imminent end of serious Falcon 9 upgrades. A continual stream of upgrades and modifications has been one of the only real constants with SpaceX’s Falcon 9 rocket: the original Falcon 9 is in almost every respect a completely different rocket when compared to the Falcon 9 Full Thrust (FT/1.2) of the present. However, one final leap is expected for Falcon 9, this time almost exclusively intended to improve the vehicle’s reliability and reusability as SpaceX rapidly approaches its first flights of Crew Dragon and dreams of rapid and repeated booster reuse.

While it was a small detail in an obscure sentence of one of several hour-long discussions, Brost specifically stated this:

This is arguably the most exciting tidbit provided to us by SpaceX. While it was undeniably vague and rather less than crystal-clear, it can be interpreted as something like this: once Block 5 has been introduced and begun to fly and refly both regularly and successfully, the vast majority of SpaceX’s launch vehicle development expertise will begin to focus intensely on the development and testing of BFR and BFS.

Statements from just last week made by SpaceX President Gwynne Shotwell strengthen this intuitive leap considerably, because BFR and BFS are liable to require a considerable amount of attention as they proceed through design maturation and eventually begin physical hardware testing in Texas.

Shotwell’s comments implied that SpaceX’s Boca Chica launch facilities, currently under construction, would be ready to support “vehicle tests” as early as late 2018/early 2019. Comments from earlier in 2017 indicate that SpaceX (and Shotwell) perceive Boca Chica as a near-perfect location for BFR launches (and thus BFR testing, as well). Finally, Brost’s implication that SpaceX’s exceptional team of brilliant and innovative launch vehicle engineers would be refocused on BFR soon after Block 5 was stable also meshes with this rough timeline. If Falcon 9 Block 5 does indeed debut within the “next few months” as Brost stated, it will have likely reached some level of design and operational maturity by the end of 2018, assuming SpaceX’s expected launch cadence.

As of right now, SpaceX is already looking at a very busy February, and currently has as many as three commercial launches scheduled within a period of maybe three weeks (GovSat-1, PAZ, and Hispasat), maybe even four if Falcon Heavy completes its first static fire later this weekend. Musk estimated that SpaceX would complete 30 missions in 2018, and a cadence anywhere near three launches per month (let alone four) would easily push SpaceX past that goal and provide the company dozens of opportunities to test, launch, recover, and relaunch their new Block 5 version of Falcon 9. As such, while BFR is probably not going to reach fully integrated hardware development or testing in 2018, it is certainly a distinct possibility, and 2019 is far more promising for the company’s interplanetary aspirations.

For now, SpaceX’s 2018 focus is quite explicitly centered on ensuring the reliability of its Crew Dragon – set to debut NET August 2018 – and Falcon 9 as it strives to complete the development of both vehicles. Up next on the company’s busy schedule is another attempt at Falcon Heavy’s inaugural static fire on Saturday afternoon, as well as the flight-proven launch of GovSat-1/SES-16, currently NET January 30.

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.
