SpaceX fires up rocket for second NASA spacecraft launch in two weeks

Published

on

SpaceX says it has successfully static fired Falcon 9 ahead of the company’s second scientific NASA spacecraft launch in just two weeks.

On November 24th, SpaceX successfully launched the small Double Asteroid Redirection Test (DART) spacecraft, marking Falcon 9’s first direct interplanetary launch and the rocket’s first flight-proven mission for NASA’s Launch Service Program (LSP). Now, as early as 1am EST (06:00 UTC) on Thursday, December 9th, SpaceX is on track to launch an even tinier NASA spacecraft known as the Imaging X-ray Polarimetry Explorer or IXPE. A telescope designed to survey some of the most extreme environments in the known universe, IXPE was originally meant to launch on the small but expensive and oft-delayed Pegasus XL rocket and weighs about 325 kilograms (720 lb) as a result.

Instead, in mid-2019, SpaceX effectively stole NASA’s IXPE launch contract out from under Orbital ATK in the midst of chronic delays of a different Pegasus XL NASA mission, bidding just over $50 million to launch the smallsat on Falcon 9. Some two years behind schedule when it finally completed the mission, Pegasus XL ultimately launched NASA’s similarly small ICON spacecraft in October 2019 for the equivalent of ~$66 million in 2021

In other words, SpaceX is charging NASA less than Orbital ATK charged to launch ICON on a rocket capable of delivering 600 kg (~1300 lb) to low Earth orbit (LEO) to launch IXPE on a rocket capable of launching about 16,000 kg (~35,000 lb) to the same orbit. Even then, despite Falcon 9’s comparatively dirt-cheap pricing relative to the performance it offers, the IXPE launch should still be profitable for SpaceX. In the recent past, CEO Elon Musk and a few other executives have indicated that the cost to SpaceX to launch a flight-proven Falcon 9 is between $15 million and $28 million depending on how costs are measured.

That is to say that even at $50M, SpaceX has plenty of breathing room to drop launch costs even further if it ever runs into actual competitive pressure. Since the first booster recovery in December 2015 and the first booster reuse in March 2017, Falcon 9 is still the world’s only reusable orbital-class rocket. IXPE is the latest in a line of NASA missions to benefit from SpaceX’s unprecedented private expertise and the company has assigned Falcon 9 booster B1061 to launch the ~$140M spacecraft.

The booster has currently launched eight astronauts, three Dragons, and one large geostationary communications satellite in its four-launch, 13-month career and IXPE will be the booster’s fifth spaceflight and orbital-class launch since November 2020. It will also be the smallest dedicated payload a Falcon 9 rocket has ever launched by a large margin, making for a very empty payload fairing at liftoff.

On December 4th, SpaceX successfully performed a launch rehearsal, fully fueling Falcon 9 B1061 and a new upper stage and briefly firing up the booster’s nine Merlin 1D engines to verify that the vehicle is ready for flight. The company has since brought Falcon 9 horizontal and rolled it back into Kennedy Space Center (KSC) Pad 39A’s main hangar, where the rocket’s payload fairing – containing IXPE – will be attached to the rest of the stack. IXPE will be SpaceX’s 28th launch in 2021 (a new record) and is the second of four or five East Coast Falcon 9 launches planned this December.

Tesla seems to be putting a lot of effort into growing its Semi team. As per recent reports, the company has hired over 1,000 factory workers in Nevada for its Semi program.

The update was initially reported by Insider, which cited three people reportedly familiar with the matter. 

Bigger Semi Team

As per the publication’s sources, Tesla has reportedly hired over a thousand new factory workers for the Semi program in Nevada. The hiring ramp is reportedly part of the company’s efforts to fulfill the orders for the Semi, which have been accumulating for years.

To help the new members of the Semi team, Tesla has reportedly brought in the new workers to Giga Nevada for training and tours over the past months. These efforts are quite a notable update for the Semi program, the publication’s sources claimed, since less than 100 factory workers were reportedly assigned to the Class 8 all-electric truck until recently.

Tesla has not issued a comment about the matter as of writing.

Tesla Semi Jobs and Updates

Insider’s report came amidst a hiring ramp in Tesla’s Careers website. As per previous reports, Tesla’s Careers website has uploaded over 80 positions related to the Semi program. The positions are varied, with listings being posted for engineering-related roles in Palo Alto, California, to manufacturing-related roles in Sparks, Nevada, and vehicle service-related roles in Sacramento, California. 

Tesla also shared a recent video of the ongoing progress of the Semi factory’s construction near Giga Nevada. As per Tesla Semi program lead Dan Priestley, the company has spent the last few months building the facility’s shell, so efforts are now underway to equip the factory with production equipment. The Tesla executive also reiterated the company’s target of producing 50,000 units of the Semi annually from its Nevada factory.

Elon Musk jokes he will join Mr Beast’s “100 Men vs 1 Gorilla” challenge

It’s a good sign, if any, that the overworked Musk is becoming a bit more lighthearted again.

Following the first quarter Tesla earnings call, CEO Elon Musk seems to have become a bit more relaxed—relaxed enough to joke about fighting a gorilla with 99 other people, at least.

It’s a good sign, if any, that the overworked Musk is becoming a bit more lighthearted again and not too busy picking fights with politicians on social media.

The Viral 100 Men vs 1 Gorilla Challenge

Over the weekend, a post on social media platform X went viral. The post itself was quite simple, with user @DreamChasnMike stating that he thinks 100 men could beat one gorilla. “Everybody just gotta be dedicated to the sh*t,” the X user joked. The post exploded on the platform, garnering 284 million impressions as of writing.

The silly question also triggered a massive debate about whether 100 men would really stand a chance against a literal gorilla. Some users even lamented that the premise was a sign of male hubris. Nevertheless, the question proved to be a fun topic on X, with some more dedicated users even posting simulated videos of what the “100 Men vs 1 Gorilla Challenge” could look like. 

Mr. Beast and Elon Musk Join In

The premise is quite similar to other viral videos from noted YouTube creator Mr. Beast, so it was no surprise that edited images of Mr. Beast YouTube thumbnails with “100 Men vs a Gorilla” also started spreading on the social media platform. Mr. Beast, who tends to be game to such silly ideas, actually reposted the edited image, joking “Need 100 men to test this, any volunteers?”

In true Elon Musk fashion, the Tesla and SpaceX CEO noted that he would join the challenge. “Sure, what’s the worst that could happen” Musk wrote in his post on X. Musk’s reply triggered quite a few laughs on X, with some stating that the world probably still needs the CEO.

While silly, Musk’s comment and his recent, more frequent posts about his companies’ products like Starlink and Grok have been received well by his supporters. Over the past months, after all, Musk has been very political and quite confrontational on social media. With Musk soon taking a step back from the Department of Government Efficiency’s (DOGE) daily operations, however, it seems like X will soon get a more tempered and lighthearted Elon Musk once more.

Big Tesla win? Sec Lutnick says cars with 85% domestic content will face zero tariffs

That’s a big competitive advantage for Tesla’s best-selling vehicle.

It appears that Tesla may see itself with a notable advantage in the United States.

This is, at least, as per recent comments from United States Commerce Secretary Howard Lutnick.

Lutnick’s Comments

In recent comments to reporters, Lutnick stated that vehicles finished in the United States with 85% domestic content will have no tariff applied, as noted in a report from The Guardian. Automakers that meet this threshold stand to gain an advantage in the U.S. auto sector, especially considering the Trump administration’s aggressive tariffs.

As per Lutnick, the administration’s auto tariffs will apply to foreign carmakers that are building their vehicles in the United States. “This is ‘finish your cars in America and you win’,” Lutnick stated.

Big Tesla Advantage

Lutnick’s comments were received positively by Tesla watchers on social media, many of whom noted that the threshold would probably be met only by the electric vehicle maker’s cars. Teslas that are sold in the United States are built in the United States, and they have consistently ranked among the most American cars in the country for several years running.

Back in December, for example, American University’s Kogod School of Business released its Made in America Auto Index, which explores the total domestic content of vehicles that are available for purchase today. In its rankings, only three vehicles received a total domestic content score of 85% or higher—the Tesla Model Y, Model Y Long Range, and the Model 3 Performance.

The two Model Y variants received a total domestic content score of 85%, while the Model 3 Performance had a total domestic content of 87.5%. If Secretary Lutnick’s comments are any indication, these three vehicles would be subjected to zero tariffs. This bodes well for Tesla, as the Model Y is the company’s best-selling vehicle by a notable margin.
