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

Published

on

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 owner fixes common feature complaint with crafty DIY retrofit

Published

Tesla owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.

Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.

There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.

Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.

Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.

Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.

He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.

For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.

Tesla exec says Roadster unveil is soon — for real this time

The Tesla Roadster unveiling could be coming “in a few weeks,” according to the company’s Chief Designer Franz von Holzhausen, who said at the Tesla Takeover Europe Event in Austria that the all-electric hypercar could finally make its way to the production line after years of anticipation.

Von Holzhausen delivered the news just days after The Information reported that Tesla planned to push the Roadster unveiling to August. It was slated for both April and May of this year, but now it seems the company is leaning toward a late Summer event to cap off the heat with perhaps its most anticipated vehicle of all-time.

Franz has been with Tesla since 2008, and has played a pivotal role in the iconic design language the company has utilized with its vehicles. Speaking to the crowd in Austria virtually, von Holzhausen’s comments injected fresh excitement into a project that has been plagued by delays for nine years.

The second-generation Roadster promises to redefine supercar standards. Tesla’s website still highlights ambitious targets: 0-60 mph in under 1.9 seconds (with optional SpaceX thruster pack potentially achieving 1.1 seconds or less), a top speed exceeding 250 mph, and a range of about 620 miles.

Equipped with a tri-motor all-wheel-drive setup delivering over 1,000 horsepower, the four-seater aims to blend blistering acceleration, everyday usability, and innovative features like cold gas thrusters for short-hop capabilities, technology that will combine the project with SpaceX.

But years after the company promised to start production, which was slated for 2020, the timeline for the Roadster has continued to shift.

Tesla has strung along those who have put $50,000 deposits down, as well as fans and enthusiasts of the company who have been long awaiting the company to bring forth a car truly designed for the human driver, and not autonomy. The Roadster is more than just a halo vehicle for Tesla; it showcases the company’s ability to push the boundaries while incorporating synergies from other Musk companies.

However, it has to make it to production, which is something Musk and Co. have pushed back repeatedly.

As Tesla navigates Robotaxi development and broader autonomy goals, the Roadster serves as a reminder of its performance roots. If von Holzhausen’s timeline holds, fans could witness this engineering marvel by late June or early July 2026. Whether a full unveiling, demo, or initial deliveries, it marks a milestone for electric supercars.

Tesla Roadster unveiling gets pushed again, but new event details emerge

Tesla has reportedly pushed the unveiling of the Roadster once again, but there are also evidently new details about the event that the company plans to show off.

The Information reported this morning that Tesla will now unveil, for the second time, the next-generation Roadster in August, a further delay from the multiple timeline that the company had previously stated.

The report has not been confirmed or denied by Tesla at any capacity.

It also states the unveiling event will take place in Texas, the same place that Tesla executives revealed in May would be the place of manufacture for the company’s highly-anticipated supercar, which boasts a top speed of over 250 MPH and 650 miles of range, according to its website.

Tesla is also expected to showcase the SpaceX package, which will be used for faster acceleration and potentially hovering capabilities, at the unveiling event, the report states. Musk has always planned for this to happen, but now it seems it is more realistic than ever

The Roadster has had its unveiling date and manufacturing date pushed back on many occasions. It was set to start production in 2020, but the COVID-19 pandemic crippled supply chain operations, forcing Tesla to push its timeline back considerably.

However, COVID has been over for some time, and Tesla has still not managed to successfully schedule and execute an unveiling event, which is something fans and enthusiasts, as well as those who have put down a $50,000 deposit, have been waiting for.

The vehicle was close to completion last year, but Musk truly wanted Lars Moravy and Franz von Holzhausen to push the limits of the Roadster. In July of last year, Moravy said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”

It is important to note two things: Tesla has not confirmed these details, and the company has regularly pushed these dates back. Until Tesla sends out formal invitations with a concrete date, taking any unveiling event reports with a grain of salt is a good idea.
