Going inside NASA’s Clean Room for a rare look at a SpaceX payload

Published

on

NASA invited media to a very special opportunity to go inside their Clean Room at the Kennedy Space Center in Florida. This is where satellites are meticulously prepared in the weeks leading up to their scheduled launch date. Of course, I was there, I wouldn’t miss this for the world!

The Press Accreditation Office is an unassuming building that’s located off the beaten path and a few miles outside KSC gates. It’s a convenient location for a large gathering of people that need to avoid traffic congestion. The building itself looks like an abandoned gas station without pumps, mostly vacant inside, except for a couple of tables and bathrooms. There’s really nothing inside – not even a coffee maker (I’m shocked by this). It serves its purpose perfectly though – get media personnel checked in and loaded onto a bus, quickly.

I was anxious to go inside NASA’s Clean Room and catch a glimpse of SpaceX’s upcoming payload.

The payload and our Solar System’s latest remote camera is called ‘TESS’ – The Transiting Exoplanet Survey Satellite. Technically speaking, it is a NASA Astrophysics Explorer mission designed to perform an all-sky survey to detect transiting planets around the closest brightest stars by monitoring their brightness with high precision. Simply put, it’s a satellite containing four insanely great cameras that will photograph the sky and detect planets around nearby stars!

After passing through the usual K-9 unit sniff test, I boarded a NASA bus and was taken through parts of the Kennedy Space Center that you don’t ever see while on the standard tour. We were traveling through heavily wooded back-of-the-property roads and for good reason. We were going to NASA’s Payload Hazardous Servicing Facility.

We were first escorted into the conference room, which is separated from the building containing the Clean Room. A bunch of swag-bags for press were being handed out, one for each of us, as we walked inside. The room was furnished with a large board-table with a huge flat-screen TV attached to the wall at the head of the table. Hanging on the walls were stunning high-resolution black and white prints of planets and moons, the same ones you’ve seen on the internet, evenly separated and precisely level. TESS mission experts were sitting at the table waiting for us to take our seats. As I sat down, I noticed some hardware on the table that we would soon be able to get our hands on.

MIT’s George Ricker – TESS’ Principal Investigator promptly started his lecture about the details of the satellite and the mission. This would be my first MIT-level lecture and I was absolutely captivated because it was organized and explained logically. George is an excellent teacher, very articulate in his descriptions of everything and had the help of great animations on the screen.

You know that scene in Interstellar where the main characters stumble into ‘NASA’ and they’re given a lecture on the ‘anomaly’ that was discovered in our solar system? That’s the scene here, except this was reality – we are discovering distant planets around other Sun’s.

There are a ton of impressive features of TESS that I can hardly pick a favorite to tell you about. It has four custom-made high-resolution cameras. The CCD’s (camera sensors) are the largest and most perfect sensors that have ever been developed for a spacecraft. The experts, luckily, had one extra sensor to pass around for us to get a hands-off, drool-worthy close-up look. If you know about full frame 35mm sensors – get a load of this one!

Next up was one of the extra lens-elements that are inside each of the four cameras. I keep a lens cloth in my pocket so once I received it I gave it a soft wipe-down and captured a few iPhone pictures of the different reflections in the lens coating. I’m still hoping for an answer about what this lens is coated with but I may never find out, though. But isn’t it intriguing?

Perhaps my favorite part of the lecture was learning about how they’re getting this satellite into orbit. This is where orbital dynamics becomes a bit like mixed martial arts with Newton’s laws of motion.

TESS is launching aboard a SpaceX Falcon 9 with a very slim window of opportunity – about 1 minute per day because it has to be perfectly in sync with the orbit of our Moon. As George Ricker explained, “This is a type of orbit that is normally unstable. If you aren’t careful about the way you launch into this orbit, you’re almost guaranteed to hit the Moon within four years. So, there’s a delicate balance staying in this orbit and there’s been a lot of effort that has gone into figuring it out. If you actually manage to do this, it’s stable for decades!”

After transporting into space from Cape Canaveral, via a SpaceX Falcon 9 rocket, the satellite is going to orbit Earth three times, and during each of its closest approaches, the satellite’s hydrazine propulsion system is going to propel it faster, essentially pumping the orbit farther out until it reaches the distance of the Moon. They timed this approach perfectly so that TESS does a ‘lunar flyby’ that will swoop beneath the Moon and use its gravity to speed-up the spacecraft and change its inclination from an East to West orbit to a new North to South orbit the will travel above and below Earth and Moon.

The reason this orbit is so elegantly chosen is that there are 300-hours of unbroken observations for photography, almost non-existent Earth-Moon light pollution. The lens hoods, also, don’t have to deal with much light or toxic radiation levels that will often destroy electronics, thus being able to remain in this orbit for several decades without any help. Absolutely awesome.

So, let’s go see TESS in the clean room.

Bunny-suit selfie!

I was transported to a very tall building and put into a small group to get dressed into bunny-suits before entering the high-bay, Clean Room. They take ‘clean’ seriously. Before stepping into the dressing room, I was escorted to a shoe scrubbing machine that had large scrubby-wheels and a vacuum to capture the particles. Then, to another device that automatically put booties on my shoes.

As I walked into the clean room, there was a sticky doormat that grabbed any particles off my booties that I picked up on the way in. I was quickly fitted with a bunny suit “You look like a large, here you go,” said a facility employee while handing me a sealed bag with a clean suit inside. We were shown how to put the suit on. Then, we went over to the glove dispensary to be sized. I noticed that their gloves were incorrectly labeled S, M, and L, according to NASA lore. I asked the employees, “Do you know about the issue this caused with the condom sizes astronauts chose?” They did not. So I was able to teach the workers a fun-fact about astronauts.

See, astronauts have egos, all of them contain the ‘Right Stuff’ but not all of them wear the same sized condoms for their spacesuit urine bags. All astronauts chose ‘Large’, not wanting to hurt their egos. Sometimes their urine condoms leaked into their spacesuit so NASA came up with a brilliant plan: Change the names of the condoms from Small, Medium, and Large to Large, Huge, and Gigantic so that all astronauts chose their appropriate sizes. It worked! But, in this case, the gloves were not labeled this way. Of course, I asked for Large. The room burst into laughter.

An employee handed me an alcohol-soaked microfiber cloth and told me to wipe down my gear perfectly before going to the next cleaning-station. This was followed by a visit to an ‘Air Shower’. It’s literally what it sounds like. There’s a small rectangular-shaped room with nozzles on the ceiling and walls that eject high-powered air all over our body. Vents in the floor sucked particles through a filter. After this final cleanse, we were checked with a blacklight … ok, just kidding. After the air shower we were granted access to the room that TESS was located: NASA’s high-bay!

The room was absolutely drenched in disorienting orange sodium lighting – a nightmare to deal with for photography and white balance but TESS was in its own protected E.T. style clean area beneath bright fluorescent lights.

In the limited time available, we were able to interview satellite experts and take as many photos as we could while technicians worked on the satellite. I love hardware images, so I set up my tripod and used my Miops Mobile remote to photograph detailed close-ups of the intricate components.

I was politely warned to not take any photographs of the hardware surrounding the satellite and keep my lens pointed only at the satellite in order to not accidentally capture something I’m not supposed to. I was very respectful and got some incredible images of things you typically will never see unless you worked on it yourself.

The spacecraft itself is quite small, there’ll be plenty of room remaining in the Falcon 9 fairing.

It’s not often I get to see a payload inside a NASA Clean Room. These are always incredible experiences.

Frequently, a mission’s importance is diminished by the fact that we’re unable to see what’s going to space and what its purpose is, mainly weather and communications satellites. They often have state-of-the-art technology on board, which is likely the reason why they want to keep it under wraps. I’m really looking forward to photographing this launch in April now that I have actually seen the payload in person.

After my time was up photographing TESS, I changed out of the bunny-suit and was brought back to the Accreditation Office. I wasted no time getting on my way to see Falcon Heavy’s Side Booster that was temporarily on display at Kennedy Space Center Visitor’s Center.

Tesla Semi futuristic sci-fi acceleration sound will never get old

Videos that capture the Semi moving at speed are most notable due to their sheer cool factor.

The Tesla Semi is not yet in mass production, but the company has accumulated over 7.9 million miles across its test fleet. With Tesla using the Semi for its operations, it is no surprise that sightings of the Class 8 all-electric truck have been abounding. 

These sightings from Tesla enthusiasts vary, but those that capture the the Class 8 all-electric truck moving at speed are most notable, possibly due to their sheer cool factor.

Tesla Semi’s Roar

There is something that just stands out with the Semi, particularly on the road. While the Semi does not have the Cybertruck’s brutalist, angular design, it is still very striking because it’s such a massive machine that moves far too quietly for its size. This is, of course, one of the reasons why the vehicle also becomes extra noteworthy when it fires up its electric motors and accelerates.

Take this video from Tesla Owners Silicon Valley, for example, which shows the all-electric hauler accelerating while pulling what appears to be a full load. In these situations, the Tesla Semi actually becomes audible, but unlike traditional diesel-powered truck, the Class 8 all-electric truck “roars” with its own, unique futuristic, sci-fi sound. In such situations, one could feel the Semi’s raw power, which comes from its three independent motors on its rear axles.

Tesla Semi Ramp

Tesla has been promoting the Semi quite a bit as of late, and recent reports have suggested that the company is putting in a lot of effort to prepare the vehicle for its production in Nevada. Tesla’s Careers website has gone live with over 80 Semi-related job openings recently as well, and a recent report has suggested that Tesla has ramped the Semi’s factory workers in Nevada to over 1,000 employees.

The company has even shared an update video of the Semi factory’s progress near Giga Nevada, as well as the design of the vehicle’s new logo. The Semi’s updated logo is quite interesting as it features elements from the Tesla Model 3’s first logo, which was unveiled way back in 2016.

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.

Possible first glimpse of Tesla “Model 2” affordable car in Fremont Factory

The models that Tesla will release in the coming months will resemble the company’s current lineup.

During the Q1 earnings call, Tesla VP of Vehicle Engineering Lars Moravy set expectations on the design of the affordable models that the company is expected to launch this 2025. As per the Tesla executive, the models that Tesla will release in the coming months will resemble the company’s current lineup.

Drone footage from the Fremont Factory earlier this month might have provided the EV community its first potential glimpse at Tesla’s affordable cars–fondly dubbed by EV fans and analysts as the “Model 2” or even “Model Q”–or at least their components and overall shape.

The Sighting

Tesla watcher and drone operator Met God in Wilderness, who has been posting aerial videos of the Fremont Factory for years now, recently shared some footage from his drone flyovers this month. While the Fremont Factory was abuzz with activity as usual, a couple of rather strange vehicles were quickly spotted by EV watchers on social media.

During the drone operator’s flyover on the 17th, for example, an unfinished vehicle could be seen parked next to what appeared to be fully-built Model S and Model Y units. What was especially interesting was the vehicle’s roof, which seemed to be slightly narrower than the Model Ys around it. Based on the video, at least, the vehicle seemed to be shaped like a crossover as well.

Footage from the 24th of April also proved quite interesting, with the drone operator capturing footage of another cryptic vehicle. Unlike the mysterious, unfinished, crossover-esque car spotted on the 17th, this particular unit seemed to have a more sloping rear, at least based on the shape of its covering.

What Lars Moravy Said

In Tesla’s Q1 2025 Update Letter, Tesla noted that “plans for new vehicles, including more affordable models, remain on track for start of production in the first half of 2025.” Tesla also noted that the new vehicles will utilize aspects of its next generation and its current platforms. They will also be produced on the same manufacturing lines as its present vehicle lineup, likely the Model Y and Model 3. 

During the earnings call itself, Moravy specifically stated that the new models that would come out in the next months would resemble the company’s current vehicles. They will, however, be affordable. “Models that come out in next months will be built on our lines and will resemble, in form and shape, the cars we currently make. And the key is that they’ll be affordable, and you’ll be able to buy one,” Moravy stated.

Watch the drone operator’s footage from April 17 below.
