SpaceX’s next Falcon Heavy launch slips into 2021
SpaceX’s next Falcon Heavy launch – set to be the rocket’s fourth overall – has slipped several months into 2021 according to the vice commander of the US Air Force Space and Missile Systems Center (USAF SMC).
Known as AFSPC-44 (now USSF-44), the nature of Falcon Heavy’s next payload remains a mystery. Headed to geostationary orbit, the satellite will likely be involved in military satellite communications, possibly including espionage (also known as signals intelligence or SIGINT). Technically, the USSF-44 mission includes two separate satellites and at least two additional rideshare payloads and will weigh roughly 3.7 metric tons (~8200 lb) at launch.
When the contract was announced, Falcon Heavy was expected to launch USSF-44 no earlier than (NET) Q4 2020. By April 2020, that target was closer to late November or December. Now, four months after that report, Brigadier General Jason Cothern says that SpaceX’s next Falcon Heavy launch is scheduled NET February 28th, 2021.
The delay doesn’t come as much of a surprise. Based on public observation of SpaceX’s Falcon booster production and testing, requiring thousands of miles of extremely conspicuous highway transport, it was already clear that the mission was unlikely to launch this year. Of the six first stages spotted in transport over the last nine months, all were clearly Falcon 9 boosters and lacked any of the telltale parts that distinguish Falcon Heavy side and center boosters.
The most recent ‘core spottings’ – a new Falcon 9 booster headed West after acceptance testing and another preparing for acceptance testing in Texas late last month – all but confirmed that USSF-44 was significantly delayed. Since mid-2019, SpaceX has intentionally slowed down Falcon booster production to focus on the higher-volume production of expendable hardware (fairings and second stages). While the company could technically complete boosters every two weeks if its feet were put to the coals and has generally averaged 10 per year, that figure has dropped closer to 6-8 boosters per year over the last ~18 months.
Coupled with a report that all three of the USSF-44 Falcon Heavy rocket’s boosters would be brand new, the lack of sightings in the wild implied that has yet to ship even one of those complex rockets to McGregor, Texas for acceptance testing. Based on preparations for Falcon Heavy’s April 2019 Block 5 launch debut, the process of testing three new Falcon boosters singlehandedly takes at least three months. Additionally, all three of the Arabsat 6A mission’s new Falcon Heavy boosters arrived in Florida a full two months before launch.
In other words, given that a brand new Falcon 9 booster rolled out of SpaceX’s Hawthorne, CA factory on August 24th and that said factory isn’t really set up for concurrent booster completion, it would take unprecedented feats of manufacturing and testing for Falcon Heavy Flight 4 to be ready to launch less than four months from now (around the turn of the New Year).
In fact, even under the assumption that the next three boosters on SpaceX’s factory assembly line are all for Falcon Heavy Flight 4, the new February 2021 launch date is going to be a tight deadline. There is no evidence that SpaceX production delays are to blame for the USSF-44 launch delay and the coronavirus-related disruption of satellite production is equally – if not more – likely. Either way, SpaceX’s fourth Falcon Heavy launch will have to wait a few extra months. Barring a surprise mission over the next six months, Falcon Heavy Flight 4 will also be SpaceX’s first operational launch directly to geostationary orbit (GEO).

Tesla utilizes its ‘Rave Cave’ for new awesome safety feature
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla is utilizing its ‘Rave Cave’ for an awesome new safety feature that will arrive with the upcoming Spring Update for 2026.
Part of the massive interior overhaul of both the Model 3 “Highland” and Model Y “Juniper” was the addition of interior accent lighting to help bring out the mood of the vehicle, increase the customization of the interior, and to create a unique listening experience.
Tesla added a Sync Lights feature that will strobe the accent strips with the beat of the music.
It is one of the most unique and one of the coolest non-functional features of a Tesla, as it does not improve the driving of the vehicle, but makes it a cool and personal addition to the interior.
However, Tesla is going to take it one step further, as the Rave Cave lights will now be used for blind spot recognition. This feature will be added as the Spring 2026 Update starts to roll out.
A lot of CRAZY new features coming with Tesla’s 2026 Spring Update, including a new FSD app!
– Self-Driving App (AI4 hardware): New app in App Launcher > Self-Driving for one-tap FSD subscriptions, activation guides, and ongoing stats.
– “Hey Grok”: Voice-activated Grok with… https://t.co/ljeYPlq9Qt— TESLARATI (@Teslarati) April 13, 2026
Tesla writes:
“Accent lights now turn red when an object is in your blind spot and your turn signal is engaged, or when an approaching object is detected while parked.”
This neat new safety feature will now increase the likelihood of a driver, who is operating their Tesla manually, of seeing the blind spot warnings that are currently available on the A pillar and on the center touchscreen.
These new alerts will now warn drivers of cross traffic as they back out of a parking space with little to no visibility of what is coming. It is a great new addition that will only increase the safety of the vehicles, while also utilizing something that is already installed in these specific Model 3 and Model Y units.
The Model 3 and Model Y were the central focus of the Spring 2026 Update, especially considering the fact that the Model S and Model X are basically gone, with only a few hundred units left. Additionally, Tesla included new Immersive Sound and Car Visualization for the Model 3 and Model Y specifically in this new update.

Tesla parked 50+ Cybercabs outside its Texas Factory with some crash tested
Dozens of Tesla Cybercabs have been spotted at Giga Texas crash testing facility ahead of launch.
Drone footage captured by longtime Giga Texas observer Joe Tegtmeyer shows over 50 units of Tesla Cybercab at the Austin factory campus, including several units clustered by Tesla’s on-site crash testing facility.
The outbound lot at Gigafactory Texas sits just outside the factory exit and serves as the primary staging area where finished vehicles are held before being loaded onto transport carriers or dispatched for validation testing. On any given day, the lot holds a mix of Model Y and Cybertruck units alongside the growing Tesla Cybercab fleet, as can be seen in the drone footage captured by Joe Tegtmeyer.

Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.
