NASA has announced that SpaceX’s Falcon 9 rocket – using a flight-proven booster – will launch the ~300 kg (670 lb) Imaging X-ray Polarimetry Explorer (IXPE) spacecraft no earlier than April 2021.

Intriguingly, IXPE was originally planned to launch on Orbital ATK (now Northrop Grumman’s) Pegasus XL but NASA never followed through with a launch contract. The move to SpaceX’s Falcon 9 rocket is likely related to the extremely disruptive and expensive launch delays NASA’s Ionospheric Connection Explorer (ICON) spacecraft has suffered at the hands of its Pegasus XL rocket. Capable of launching less than 450 kg (1000 lb) to low Earth orbit, Pegasus XL has been lucky to launch annually over the last decade or so and carries a price tag of no less than $50M-$60M today.

Small rocket, huge delays

Defying its small size, Pegasus XL was originally scheduled to launch ICON in December 2017. Delayed by unspecified problems with launch vehicle hardware, the mission was pushed back an inexplicable 10 months to October 2018, where additional issues with the rocket again indefinitely scrubbed a launch attempt. In early 2019, the launch was tentatively scheduled for Q2 2019, while – as of July – ICON is not expected to launch before September 2019.

All said and done, in the increasingly unlikely event that Pegasus XL is ready for launch this September, the ICON spacecraft – ready for launch since late-2017 – will have been delayed more than 21 months by problems with the rocket.

Again, for the small-scale performance of Pegasus XL, the rocket still carries a price tag of more than $50M – NASA’s ICON launch contract was valued at more than $56M. Conscious of this, SpaceX has managed to sway NASA to launch the small IXPE spacecraft on a flight-proven Falcon 9 at a cost of just $50.3 million, easily the lowest Falcon 9 launch contract cost ever publicized.

In recent months, SpaceX executives have made comments indicating that Falcon 9’s default base price – likely assuming a flight-proven booster – is now as low as $50M. July 8th’s NASA launch contract is the first direct confirmation of that exceptionally affordable pricing, likely also indicating that the base price for Falcon 9 is even lower for commercial customers with less stringent requirements.

Barring an unexpected contract between now and IXPE’s expected April 2021 launch, the mission will probably be the first time that a dedicated flight-proven SpaceX rocket launches a scientific spacecraft for NASA. SpaceX’s next dedicated NASA launch – the ESA-built Sentinel 6A spacecraft – is scheduled to no earlier than November 2020 and is likely to fly on a new Falcon 9 booster.

In April 2019, NASA awarded SpaceX $69M for Falcon 9 to launch the agency’s Double Asteroid Redirect Test (DART) – an asteroid-impactor spacecraft – no earlier than June 2021. IXME is SpaceX’s second NASA launch contract win of 2019.

According to NASA, “IXPE will fly three space telescopes with sensitive detectors capable of measuring the polarization of cosmic X-rays, allowing scientists to answer fundamental questions about these turbulent environments where gravitational, electric and magnetic fields are at their limits.”

Tesla’s Omead Afshar, known as Elon Musk’s right-hand man, leaves company: reports

Tesla’s Head of North American sales and European ops, Omead Afshar, has reportedly left the company. He was widely-known as Elon Musk’s right-hand man.

Tesla’s Omead Afshar, who is widely known as CEO Elon Musk’s right-hand man, has reportedly left the company.

Several outlets are reporting that Afshar either left voluntarily or was potentially terminated on Thursday. His LinkedIn profile has not been updated to reflect this, and still states he presently works at Tesla in the “Office of the CEO.”

Afshar was promoted to Head of North American sales and European operations late last year. We reported on his promotion in October, as he was previously a Project Manager in the Office of the CEO before Musk and co. stepped up his responsibilities.

According to the initial report on Afshar’s departure from Bloomberg, the news has been circulating throughout the company in recent days. His name no longer appears in the company’s internal directory.

It is interesting to think about what could have caused this. Tesla has felt some pressure in Europe with struggling sales figures in some markets. It is the second-best-selling EV maker in the region, with Volkswagen performing slightly better for the year, according to EU-EVs.

Tesla’s Model Y is the best-selling EV in the region.

While the company has not directly confirmed the news, it appears to be true based on the reports.

Tesla is usually relatively quick to dispel any headlines that go out from mainstream media that are not factual. This has yet to be responded to by any executive, including Musk.

Afshar has been with Tesla for seven years and ten months, first joining in September 2017 as a Project Manager in the Office of the CEO.

He then became a Project Director, before his job title was updated to a Cowboy hat emoji in July 2020, around the time Tesla started moving some things to Texas.

Forbes is reporting that Afshar was terminated and did not leave voluntarily. This has yet to be confirmed.

xAI Colossus pollution concerns in Memphis continue

NAACP & SELC push back against xAI Colossus supercomputer. City tests say air is safe — but activists aren’t convinced.

Politicians in Memphis continue to debate about the pollution concerns arising from the xAI Colossus supercomputer.

The NAACP and the Southern Environmental Law Center (SELC) have already expressed interest in filing a lawsuit against xAI over concerns related to air pollution stemming from its gas-powered turbines. Environmental groups have now raised concerns about water pollutants.

On Tuesday, Memphis released third-party air quality test results from June 13 and 16. The tests were conducted in downtown Memphis, Whitehaven, and Boxtown, two miles from xAI’s site. The city claimed levels of 10 pollutants tested were safe.

However, SELC–which is representing the NAACP in a potential lawsuit against xAI–criticized the omission of a key pollutant called ozone from the air quality tests. SELC also noted that monitors were placed against buildings, contrary to EPA guidance, stating air sensors should be “at least six feet above ground level, rooftop, or other objects and away from obstructions, vegetation, or emissions sources that would interfere with the measurement.”

Local opposition intensified, with State Representative Justin J. Pearson asserting: “I stand firm that nothing matters if you cannot breathe clean air, drink clean water, and plant in clean soil.”

On Wednesday, concerns shifted to the Memphis aquifer, as the Tennessee Department of Environment and Conservation held a virtual meeting on xAI’s wastewater facility.

Activist Pamela Moses criticized xAI. “They are not coming here to uplift or invest in our community. They are here to exploit it. This a distressed and a historically neglected area, and instead of bringing opportunity, Colossal is bringing pollution…secrecy and broken promises,” she said.

xAI’s $80 million Grey Water facility aims to mitigate water concerns. The Colossus Water Recycle Facility, a collaboration between the Tennessee Valley Authority and Nucor Steel, aims to alleviate the strain on the aquifer.

“This project is a game changer in terms of it saving about 4.7 billion gallons of water projected, and about 4.7 billion gallons will remain in the aquifer every year,” said Bobby White of the Greater Memphis Chamber.

As xAI’s Memphis supercomputer continues to be the center of debates, the tension between economic benefits and environmental justice remains unresolved. With ongoing scrutiny and potential legal action, xAI’s efforts to address pollution and water concerns will shape its role in Memphis’ future.

Tesla Robotaxi’s biggest challenge seems to be this one thing

That big bright thing in the sky might be Tesla’s biggest challenge in terms of Robotaxi.

Tesla Robotaxi launched just a few days ago to a limited number of riders in Austin, Texas, but its biggest challenge seems to be how the automaker will figure out one thing: the Sun.

Among the company’s unique strategies, its emphasis on using cameras for self-driving is perhaps the most interesting. No other company has adopted the same strategy, as others have relied on cameras with either sensors or LiDAR rigs to accomplish their self-driving deployments.

Tesla, on the other hand, has called LiDAR unnecessary. CEO Elon Musk once called it “a fool’s errand,” stating it was not needed to build an effective self-driving fleet of vehicles.

Musk compared cameras to eyes. Humans don’t need sensors or LiDAR to operate vehicles on the road, so why should cars? This brought up some questions, especially regarding sun glare. Musk said that Tesla would use direct photon counting to see directly into brigt sunlight or even in the darkest conditions at night.

His quote during a recent earnings call was:

“Actually, it does not blind the camera. We use an approach which is direct photon count. When you see a processed image, so the image that goes from the sort of photon counter — the silicon photon counter — that then goes through a digital signal processor or image signal processor, that’s normally what happens. And then the image that you see looks all washed out, because if you point the camera at the sun, the post-processing of the photon counting washes things out.”
So far, this strategy has yielded mixed results. We have seen examples of both:

The Good

We’ve had a handful of people state that they have had no issue using the Robotaxi when it is driving into direct sunlight.

There are plenty of examples:

The Bad

The Verdict

This is obviously a weird case, and it seems that this could be one of the challenges Tesla will face with the deployment of Robotaxi.

While it will get figured out, this is something that could ultimately push back Tesla’s goal of having no safety monitor in the vehicles. However, the instance will be learned and used to improve in the future through its Neural Nets.

The first intervention was captured yesterday, requiring the Tesla safety monitor to stop the vehicle manually on the car’s touchscreen.
