In this week’s analysis, there is simply too much going on to focus on any single overarching theme. NASA awarded ~$250M to fund three commercial Moon landers, Russia revealed an impossibly ambitious schedule for its conceptual crewed Moon program, and NASA’s Office of the Inspector General (OIG) released a report that did not look kindly on the management of the Europa Clipper spacecraft’s supposed plans for an SLS rocket launch.

While it is increasingly clear that the 2020s are likely to be the most exciting period of spaceflight activity in decades, it remains equally clear that most of the world’s space exploration – despite the incredible results often produced – is poorly and inefficiently managed. Upsets may well be served by commercial hopefuls like SpaceX, Blue Origin, iSpace, and others, but we are likely set to witness another decade or so of wasteful, results-phobic human spaceflight efforts lead on a wild goose chase after NASA’s Moon return ambitions. If it ends up being anything like the SLS rocket and Orion spacecraft it is being artificially locked to, the Moon return may eventually accomplish something approximately half a decade behind schedule after vacuuming up at least $10-20B of federal funding.

At the same time, the robotic exploration expertise of NASA, ESA, Japan (JAXA), China (CNSA), India (ISRO), and Russia (Roscosmos) will be thrown at a bevy of spacecraft and landers with destinations throughout the solar system.

Europa Clipper deserves better ‘sails’

  • As of now, Congress has “mandated” that Europa Clipper and a planned Lander follow-up both launch on NASA’s Space Launch System (SLS) rockets. This was a political ploy by long-time supporter John Culberson (now a former US representative) meant to gain the support of Congressional gatekeepers focused on preserving SLS and Orion-related pork that feeds into their legislative districts or states (Sen. Shelby, Sen. Nelson, and others).
  • Developed by Lockheed Martin with the support of the European Space Agency (ESA), the Orion spacecraft is essentially an overweight, underpowered modern version of NASA’s Apollo Command and Service Module (CSM). Despite its mediocre capabilities, the spacecraft could theoretically be useful for NASA’s crewed exploration ambitions.
    • Sadly, Orion has been almost inextricably linked to NASA’s SLS rocket, built (for the most part) by Boeing and Aerojet Rocketdyne. Originally known as Ares V, the comparatively downsized SLS has always been meant to launch extremely large payloads. In theory, even the early SLS Block 1 (likely the only variant that will ever fly) would be capable of delivering ~25 metric tons to Mars and 6.3 mT directly to Jupiter.
  • That performance would also drastically cut the amount of time it takes Europa Clipper to travel from Earth to Jupiter from 6-7 years to about 3 years.
  • Hilariously, despite both Europa Clipper and SLS having been in development for years and the latter being legally required to launch the former, NASA still hasn’t verified (with certainty) that SLS Block 1 is actually capable of launching EC directly to Jupiter, the only benefit of SLS being the 3 years of time saved by a direct trajectory.
  • Even worse, despite mission delays that pushed Europa Clipper’s launch target from 2022 to 2023, NASA has yet to actually order new SLS boosters beyond the first two, assigned to Orion missions NET 2021 and 2022.
    • As NASA OIG notes, according to past estimates from NASA officials, the agency would need a minimum of 52 months (4.3 years) of lead time for Boeing and Aerojet Rocketdyne to build new SLS boosters. In other words, NASA would have had to order new boosters in September 2018 (8 months ago) for Europa Clipper to have a chance of launching on SLS in 2023.
  • Due to all of this absurd and avoidable uncertainty, large amounts of money and time are being wasted designing Europa Clipper to essentially be launcher-agnostic, able to fly on Falcon Heavy, Delta IV Heavy, or SLS. At this rate, it’s not even clear if a third SLS will be ready to launch Europa Clipper in 2024, barring a miraculously perfect performance during its launch debut (“Artemis-1”, formerly EM-1).

Dispatch from the Moon (bureaucracy)

  • Earlier this week, NASA announced its first truly Moon landing-focused contracts, awarding a total of $253M to OrbitBeyond, Astrobotic, and Intuitive Machines for commercially-developed Moon landers that could be ready for lunar landings as early as September 2020, July 2021, and July 2021, respectively.
    • Astrobotic and Intuitive Machines aim to deliver 90 kg and 100 kg of payload to the Moon’s surface, while OrbitBeyond is targeting ~40 kg despite receiving ~$25M more from NASA. Regardless, it has to be said that ~$250M is extremely cost-effective for the 230 kg (510 lb) worth of payloads it could deliver to the Moon. For comparison, in 2015, NASA purchased a single Delta IV Heavy launch (for its Parker Solar Probe) at a cost of almost $390M
    • Not only does that $250M include launch costs (two or even three of which will likely end up as copassengers on Falcon 9 launches), but it includes delivery to the surface of the Moon.
  • Additionally, an unknown proportion of that funding has clearly been directed towards the development and maturation of unflown and (mostly) unbuilt lunar landers, all of which could potentially offer even more affordable lunar delivery services once development is finished.
  • Finally, Russian space agency Roscosmos apparently has plans (or at least a Powerpoint) to land cosmonauts on the Moon as early as 2030. To accomplish that incredibly ambitious feat, Russia would effectively need to develop three entirely new rockets – two of which are far larger than anything Russia has built since the fall of the USSR – and a brand new crew and deep space-capable spacecraft (Federation).
  • The ambition is undeniably inspiring and could create a truly fascinating race-that-isn’t-really-a-race back to the Moon. However, the reality is that Russia as a country and economy is struggling, and those difficulties are obvious in Roscosmos – woefully underfunded and eternally tossed about as a political puck and source of easy embezzlement.
    • A Soyuz spacecraft launched to the ISS last year was found to have a literal hole in it, the likely result of sloppy manufacturing and nonexistent quality control. A few months later, a Soyuz 1.2 rocket failed mid-flight while launching a trio of astronauts, triggering the first human spaceflight abort/failure in almost two decades.
    • All three astronauts were safely recovered but those two failures alone suggest that Russia has some soul-searching a budget-tweaking to do before it has any chance of successfully (let alone safely) undertaking its ambitious lunar program.

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.
