SpaceX’s Falcon 9 wins launch of an asteroid-attacking NASA spacecraft

Published

Just minutes before SpaceX began fueling Falcon Heavy for its commercial launch debut, NASA announced that the company had won a contract for its Double Asteroid Redirection Test (DART) mission, to be launched by Falcon 9 for the low cost of $69M.

Designed to cost less than $250M total, the DART mission will aim to be as light and fast as possible, using a dedicated Falcon 9 to send the ~600 kg (~1300 lb) spacecraft and its Italian companion cubesat on an ~11 million kilometer (~7M mi) journey to the binary asteroid Didymos. The ultimate purpose of DART is to effectively prove out both technologies and physics that could be used in the future to defend Earth from asteroids known to be on a collision course.

If all goes as planned during DART’s imminent design review milestones and hardware integration, Falcon 9 could launch the spacecraft towards the Didymos asteroid system in June 2021 for an October 2022 arrival. That “arrival” would involve DART impacting Didymos-B – the smaller of the pair at 163 m (535 ft) across – at a relative velocity of more than 6 km/s (3.7 mi/s). Nicknamed Didymoon, Didymos-B effectively orbits Didymos-A. At that speed, the ~600 kg probe will create an impact with the equivalent explosive force of nearly two and a half tons of TNT, the purpose of which is to determine just how much the sheer kinetic energy of impact can modify a small body’s orbit around the main asteroid.

Estimates from the spacecraft’s mission managers expect Didymoon’s orbit to be shifted by about 1% as measured by the time it takes to orbit Didymos-A, from ~11.9 hours to ~11.8 to 12.0 hours. This is a very small change but one that should – in theory – be easily measurable by telescopes on Earth, despite the fact that Didymoon has been estimated to have a mass of approximately 3.5 million metric tons (7.6 billion pounds), approximately seven million times heavier than DART. In short, NASA is going to functionally bomb an asteroid moon to see if humans might be able to use kinetic impactors to gently ‘boop’ threatening space objects off of the offending trajectory years or even decades in advance.

Despite the inherently destructive, single-use nature that DART’s impactor status bestows, current plans thankfully include an Italian cubesat known as LICIACube. The small copassenger will deploy two days before impact to fully exploit the scientific value of DART’s demise with high-quality photos of the event and aftermath. LICIACube will be traveling the same speed and thus won’t be able to enter orbit around the asteroid system, but a European Space Agency (ESA) mission known as Hera plans to do just that in the mid-2020s to better characterize Didymos and the crater (hopefully) made by DART.

Aside from the mission itself, DART serves as a technology demonstration platform for NASA. It will mark the first in-space use of the NASA-built NEXT-C ion thruster and powerpack, as well as the first standalone use of Roll-Out Solar Array (ROSA) deployment mechanism (shown above being tested on the ISS). Even more intriguing is a proposed transformational solar array planned at one point for DART, a flexible combination of advanced solar cells (~33% efficient) and mirror concentrators that could feed a spacecraft five times as much power for a given solar array area and distance from the sun. It’s unclear whether this will make it into DART’s final design but it still appears to be on the table as of January 2019. According to the contracted manufacturer, DART’s solar array will produce ~6.6 kW, while rough estimates suggest that the solar array will have an area of 16 m^2 (170 ft^2). Relative to the simplicity of the deployment mechanism and small size of DART (~600 kg total), this is an incredible amount of accessible power.

Getting to orbit

For NASA’s SpaceX launch contract, the agency will pay just $69M, barely 10% above Falcon 9’s bare-minimum list price of $62M. It’s safe to assume that the timing of the contract award – days after SpaceX abruptly dropped an official protest of ULA winning a ~$150M NASA contract – might not be coincidence. Regardless, SpaceX’s decision to bid so low for a NASA launch does lend some serious credence to the company’s protest that ULA’s contract for the mission – NASA’s LUCY asteroid explorer – was “vastly more [expensive]” than the bid SpaceX submitted.

Weighing just ~600 kg (~1300 lb) wet, DART could end up launching with additional copassengers on Falcon 9, although there is a precedent set by NASA’s ~360 kg TESS and Taiwan’s Formosat-5 for SpaceX giving tiny spacecraft dedicated launches. Additionally, it’s possible that DART will launch on a flight-proven Falcon 9 Block 5 rocket, given the likelihood that NASA will have certified flight-proven SpaceX vehicles for almost any launch by 2021.

Tesla Model Y seen testing under wraps in India ahead of launch

Tesla appears to be getting closer to launching vehicle sales in India, as a few wrapped Model Y units have recently been spotted.

Following years of back and forth between Tesla and the Indian government, the automaker is finally expected to launch sales in the country in the coming months, and one of the company’s vehicles was spotted testing over the weekend.

On Sunday, a privacy-wrapped Model Y was seen driving in India and was posted on Reddit, as Tesla prepares to debut vehicle sales in the country for the first time. The news comes a little over a month after Tesla began certifying the Model Y and Model 3 for sale in the country, and as the U.S. manufacturer gets ready to launch the nation’s first store in Mumbai.

The appearance of the refreshed Model Y comes just a few days after another recent sighting in the country, in which a wrapped unit was seen driving on the Mumbai Pune Express Way.

Tesla’s vehicles can regularly be seen under privacy wraps such as this one ahead of their launch, often with the company’s vehicles before they’re officially unveiled. As such, many have speculated following the sighting that Tesla could either be preparing to launch the RWD variant launched in some markets in recent weeks, or the Performance version of the SUV, which is widely expected to debut sometime this year.

According to local reports, Tesla also signed a five-year lease on Mumbai store at the Bandra Kurla Complex, while a second store is expected to open near the New Delhi airport at Aerocity. Meanwhile, Tesla has also been hiring for the stores in recent months, along with holding a recruitment day in Mumbai last month.

Much of the delay on Tesla’s entry into India came from the country’s high import tariffs on vehicles and other products, while one of the government’s conditions for the country selling cars there was to utilize local suppliers. Last month, a rumor started circulating suggesting that Tesla was partnering with automotive company Tata Group for the local production of components such as castings, forgings, electronics, and more.

Tesla doubles down on Robotaxi launch date, putting a big bet on its timeline

Tesla continues to double down on its June goal to launch the Robotaxi ride-hailing platform.

Tesla has doubled down on its potential launch date for the Robotaxi ride-hailing platform, which will utilize the Cybercab and other vehicles in its lineup to offer driverless rides in Austin, Texas.

Tesla said earlier this year that it was in talks with the City of Austin to launch its first Robotaxi rides, and it planned to launch the platform in June.

This has been a widely discussed timeline in the community, with some confident in the company’s ability to offer it based on the progress of the Full Self-Driving suite.

However, others are skeptical of it based on Tesla’s history of meeting timelines, especially regarding its rollout of FSD.

Nevertheless, Tesla was asked when it would be able to offer Robotaxi rides and where, and it clearly is not backing down from that June date:

It is getting to a point where Tesla is showing incredible confidence regarding the rollout of the Robotaxi in June. We have not seen this kind of reiteration regarding the rollout of something regarding autonomy from Tesla at any point in the past.

CEO Elon Musk has even been increasingly confident that Tesla will meet its target. Earlier this week, he said the vehicles will be able to roll off production lines and drive themselves straight to a customer’s house:

Elon Musk continues to push optimistic goal for Tesla Full Self-Driving

There could be some discussion of an acceptable grace period, as the timeline for the Robotaxi rollout could still be considered a success, even if it were a month or two late. However, if it were pushed back further into 2025 or even 2026, skepticism regarding these timelines would continue to persist.

As of right now, it seems Tesla is extremely confident it will meet its goal.

Tesla Semi fleet from Frito-Lay gets more charging at Bakersfield factory

Tesla Semis showcased at Frito-Lay plant in Modesto, CA
Frito-Lay transformed its Modesto, Calif., site by replacing diesel fleet assets with ZE and NZE alternatives and installing fueling and charging infrastructure for the new fleet as well as on-site renewable energy generation and storage.

Among the several companies that have had the opportunity to add Tesla Semi all-electric Class 8 trucks to their fleets earlier than others, the most notable is arguably Frito-Lay, which has utilized the vehicle for a couple of years now.

However, as their fleet is making more local runs and there are undoubtedly plans to expand to more Semi units, the company has recognized it needs additional Megachargers to give juice to their trucks.

As a result, Frit-Lay decided to build more chargers at their Bakersfield, California facility, according to new permits filed by Tesla:

There are already chargers at the company’s Modesto, California, factory, but Bakersfield is roughly three hours south of Modesto.

Interestingly, Tesla is calling the chargers “Semi Chargers” in the filing, potentially hinting that it is no longer referring to them as “Megachargers,” as they have been in the past. This is a relatively minor detail, but it is worth taking note of.

In 2022, Frito-Lay began installing these chargers in preparation for the Semi to become one of the company’s main logistics tools for deliveries in California and surrounding states.

Frito-Lay is not the only company that has chosen to utilize the Tesla Semi for these early “pilot” runs. PepsiCo has also been a company that has used the Semi very publicly over the past two years.

Additionally, the Tesla Semi participated in the Run on Less EV trucking study back in late 2023, where it managed to complete a 1,000-mile run in a single day:

Tesla is planning to ramp production of the Semi late this year. On the Q4 2024 Earnings Call, VP of Vehicle Engineering Lars Moravy said the company would be focusing on the first builds of the Semi’s high-volume design late this year before ramping production in the early portion of 2026:

“We just closed out the Semi factory roof and walls last week in Reno, a schedule which is great with the weather. In Reno, you never know what’s going to happen. But we’re prepping for mechanical installation of all the equipment in the coming months. The first builds of the high-volume Semi design will come late this year in 2025 and begin ramping early in 2026.”

Tesla will build these units at a new Semi production facility located in Reno near its Gigafactory. The company is getting closer to finishing construction, as a drone video from this morning showed the facility is coming along at a good pace:
