SpaceX reportedly plans to submit its own human-rated Moon lander design for NASA’s latest major request for proposal (RFP), part of the agency’s rough plan to return humans to the Moon no earlier than 2028.

Meant to begin delivering NASA astronauts to the surface of the Moon as early as 2028, the agency hopes to base those lander operations on a thus far unbuilt space station orbiting the Moon with the support of its SLS rocket and Orion spacecraft.

Meant to build directly off of SLS/Orion, a NASA-designed rocket and spacecraft beset with at least three years of delays and billions of dollars in cost overruns, it’s unclear where SpaceX might fit into NASA’s latest modernized attempt at an Apollo Program 2.0. Alongside the 2017 cancellation of Crew Dragon’s propulsive landing program due in part to the likely cost of the certification burden NASA would have placed on the technology before allowing it to land astronauts, SpaceX also canceled Red Dragon (and thus Grey Dragon), a proposal to use a minimally modified version of Crew Dragon as an ad-hoc Mars lander and R&D testbed.

Aside from the likely cost of certifying propulsive Crew Dragon to NASA specifications, CEO Elon Musk also explained the program’s cancellation as a consequence of SpaceX’s far greater interest in what he described as “vastly bigger ship[s]” in July 2017. This translated into a presentation at IAC 2017 a few months later, where Musk revealed SpaceX’s updated design for a giant, fully-reusable launch vehicle meant to enable sustainable Mars colonization, known then as BFR. BFR has since been reconceptualized at least two more times, settling (at present) on a radical new approach said to rely heavily on stainless steel as a replacement for advanced carbon composites.

In the second half of 2018 and the first few months of 2019, the SpaceX CEO’s BFR (now Starship/Super Heavy) narrative has noticeably diverged from a largely exclusive focus on Mars to include a new interest (be it genuine or out of convenience) in the Moon. Most notably, Musk stated in January and February 2019 that SpaceX’s single-minded goal for BFR was now “to reach the moon as fast as possible”.  In response to a question about SpaceX’s intentions for the first few orbital BFR (Starship) launches, Musk also replied, “Moon first, Mars as soon as the planets align”.

This is likely explicitly connected to Japanese billionaire Yusaku Maezawa’s decision to purchase the first operational Starship (BFR) launch in support of his philanthropic #DearMoon project, meant to send 8-10 artists from across Earth on the first commercial voyage around the Moon as early as 2023. While no specific value was given, the implication of CEO Elon Musk’s emotional response when discussing the financial support pegged the number in the hundreds of millions of dollars, likely on the order of $250M to $500M. However, any astute bureaucrat or aerospace executive would also be (and have been) distinctly aware of a new political undercurrent pushing for the US and NASA to return humans to the Moon, circulating for the last few years before breaking through to the surface in the last six or so months.

Orion/SLS versus Starship/Super Heavy?

Per Musk’s frequent and insistent comments on just how hard he expects it to be for SpaceX to fully fund the development of BFR, it would come as no surprise to learn that SpaceX had set its eyes on potential sources of major BFR development funds. Where exactly NASA will find the multibillion-dollar sum likely required to develop even a commercial human-rated Moon lander is entirely unclear, but alas. Although NASA’s new Moon mission seems like an apt fit for SpaceX, funding aside, the problem remains that SpaceX’s next-generation Starship/Super Heavy (formerly BFR) launch vehicle poses a direct, existential threat to NASA’s SLS rocket and Orion spacecraft, an almost entirely expendable system likely to cost no less than $1B per launch and unlikely to launch for the first time until 2021.

NASA’s human return to the Moon is meant to directly complement SLS/Orion thanks to the intention of using a theoretical Moon-based space station (known as Gateway) in a bizarre lunar orbit (known as a  “Near Rectilinear Halo Orbit” or NRHO) as the base of lunar-landing operations. The decision to place said Gateway in a lunar halo orbit derives almost exclusively derives (PDF) from a separate decision to design NASA’s future exploration plans around SLS and Orion, particularly Orion in the context of the Moon. Put simply, Orion is relatively mass-inefficient and has a fairly limited amount of delta V (shorthand for the capacity to change one’s velocity), preventing far more useful orbits (i.e. actual lunar orbits). The fragile web of Gateway, SLS, Orion, and any potential crewed Moon landers is intentionally designed to be interdependent, meaning that each piece on its own makes little objective sense and has no obvious functional benefit relative to a bevy of alternatives.

 

As designed, SpaceX’s Starship/Super Heavy combo would be a nearly redundant and radically simpler solution to the mishmash of Gateway, SLS, Orion, and others. A return to using propulsive Crew Dragon landings as a method of significant payload delivery to the lunar surface is immensely unlikely. The value of an entirely new SpaceX-built craft is equally unclear, given Musk and SpaceX’s general stance on putting development funds towards things that bring the company closer to achieving its ultimate goal of sustainable interplanetary colonization. Regardless, it will undoubtedly be exciting to see what happens and whether SpaceX actually chooses to submit a proposal for one or all aspects of NASA’s baselined lunar lander.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Published

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

SpaceX just got the green light Starship has waited years for

The FAA has cleared Starship Flight 14, setting up SpaceX’s first orbital attempt on Monday.

SpaceX has cleared the last regulatory hurdle standing between Starship and its first trip to orbit. The Federal Aviation Administration issued the launch license for Starship Flight 14 late Saturday, keeping the mission on track for liftoff Monday, September 28, from Pad 2 at Starbase, Texas.

The 75 minute launch window opens at 7:15 a.m. Central, and Boca Chica Beach closures are also scheduled for September 29 and 30 as backup dates. This will be Starship’s first revenue generating mission.

The license was the missing piece after SpaceX completed a full wet dress rehearsal with Booster 21 and Ship 41 on September 24. At the time, the company said the flight remained on track pending regulatory approval. Because Flight 14 flies an orbital profile, the FAA had to sign off on a modified license that met its safety, payload and financial responsibility requirements.

Observers combing through the new FAA paperwork also noticed that lightning no longer appears among Starship’s listed launch hazards. If that holds, it matters more for where Starship is headed than for Monday’s attempt. Florida and Louisiana, home to LC-39A and the planned Starbase Louisiana site, see some of the most frequent lightning in the United States.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

Flight 14 is the mission SpaceX has been building toward for months. Ship 41 will carry 26 Starlink V3 satellites, the first operational V3 units to be deployed, and attempt roughly six orbits at about 275 kilometers over a flight lasting just under 10 hours. SpaceX says the ship will only perform its orbital insertion burn after flight controllers confirm enough hardware redundancy remains for the deorbit burn at the end of the mission. Ship 41 is targeting a splashdown in the Pacific west of Chile, while Super Heavy will return to the Gulf of Mexico.

The date carries some symbolism as well. A Monday launch would come 10 years and one day after Elon Musk first presented the Interplanetary Transport System, the design that became Starship, at the International Astronautical Congress in Guadalajara, Mexico.

SpaceX has not announced what comes next, but air traffic planning slides reported this week, list Flight 15 no earlier than October 19 and a first Starship launch from LC-39A in Florida no earlier than October 30. Both dates depend on how Monday goes.
