Despite bad weather that forced SpaceX to stand down from a Starlink launch planned earlier this morning, the company is still on track to attempt the first East Coast polar launch in half a century later this evening.

Known as SAOCOM 1B, the Argentinian spacecraft scheduled to launch on Falcon 9 is the second in a pair of large Earth observation radar satellites, using an advanced form of radar to analyze vast swaths of the planet’s surface. SpaceX launched SAOCOM 1A in October 2018.

Originally scheduled to launch as early as March 30th, 2020, SAOCOM 1B has suffered extensive delays as a result of coronavirus-related travel and work restrictions. At long last, the 1600 kg (~3500 lb) satellite is vertical at the LC-40 launch pad atop a SpaceX Falcon 9 rocket, but Florida’s temperamental summer weather threatens to delay the mission into September.

Per the 45th Space Wing tasked with range support for all Cape Canaveral launches, the forecast for SpaceX’s SAOCOM 1B launch predicts conditions will be just as bad as the weather that forced SpaceX to scrub its 10:12 am EDT Starlink-11 launch attempt. Said forecast shows a 60% chance of weather constraint violation (40% GO) due to cumulus and anvil cloud (i.e. thunderstorm) formation, among other concerns. While somewhat unrelated, photographers were unable to set up cameras on time due to a massive, hours-long lightning storm over Cape Canaveral Air Force Station (CCAFS) and Kennedy Space Center (KSC).

With any luck, though, SpaceX will be able to thread the needle between prevailing weather conditions and safely launch SAOCOM 1B. Historically, the company has managed to successfully launch in spite of very discouraging weather forecasts, which is why it almost never aborts launch attempts until the last minute when weather is a concern – conditions can very quickly change.

SAOCOM 1B is the first polar launch attempt from the US East Coast in more than half a century after debris from a failed rocket struck and killed a cow on Cuban land in 1969. By adding a ‘dogleg’ maneuver to tweak its trajectory mid-flight, Falcon 9 will theoretically be able to minimize the risk of a similar accident occurring while still recovering the rocket booster and (perhaps) its payload fairing halves.

After liftoff, Falcon 9 booster B1059 will attempt to return to Cape Canaveral to land at one of SpaceX’s land-based Landing Zones for the first time in almost six months. Fairing recovery ship Ms. Chief is on site to attempt to catch and recover one or both halves of the SAOCOM 1B mission’s Falcon fairing, while twin ship Ms. Tree is several hundred miles north to attempt the same feat after SpaceX’s Starlink-11 launch (now NET September 1st).

SAOCOM 1B is scheduled to launch no earlier than (NET) 7:18 pm EDT (UTC-4) on August 30th. An official webcast will begin around 7 pm.

Elon Musk argues lidar and radar make self driving cars more dangerous

The CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving.

Elon Musk is taking a firmer stance in the vision vs lidar debate for autonomous driving. In his more recent comments, the CEO is not just stating that using sensors like lidar is unnecessary to achieve self-driving. 

Musk is stating that using lidar actually makes self-driving cars more dangerous. 

Uber CEO’s comments

During a recent interview, Uber CEO Dara Khosrowshahi shared his thoughts on the autonomy race. As per the CEO, he is still inclined to believe that Waymo’s approach, which requires outfitting cars with equipment such as lidar and radar, is necessary to achieve superhuman levels of safety for self-driving cars. 

“Solid state LiDAR is $500. Why not include lidar as well in order to achieve super human safety. All of our partners are using a combination of camera, radar and LiDAR, and I personally think that’s the right solution, but I could be proven wrong,” the Uber CEO noted.

Elon Musk’s rebuttal

In response to the Uber CEO’s comments, Elon Musk stated that lidar and radar, at least based on Tesla’s experience, actually reduce safety instead of improving it. As per the Tesla CEO, there are times when sensors such as lidar and radar disagree with cameras. This creates sensor ambiguity, which, in turn, creates more risk. Musk then noted that Tesla has seen an improvement in safety once the company focused on a vision only approach.

“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins? This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways. We turned off the radars in Teslas to increase safety. Cameras ftw,’ Musk wrote.

Musk’s comments are quite notable as Tesla was able to launch a dedicated Robotaxi pilot in Austin and the Bay Area using its vision-based autonomous systems. The same is true for FSD, which is quickly becoming notably better than humans in driving.

It appears that the Tesla Model Y L has been sold out in China for September 2025. This was hinted at in Tesla China’s configurator for the all-electric crossover.

Model Y L deliveries

Since the Model Y L’s official launch earlier this month, Tesla has been pretty consistent in the idea that the extended wheelbase variant of its best-selling vehicle will see its first deliveries sometime in September. This was quite an impressive timeframe for Tesla, considering that the Model Y L has only been launched this August. 

Nevertheless, both Tesla China’s Model Y configurator and comments from company executives have noted that the vehicle will see its first customer deliveries in September. “Tesla cars are fun to drive alone, whether you have children or how many children, this car can meet all your needs. We will deliver in September and wait for you to get in the car,” Tesla China VP Grace Tao wrote on Weibo.

October 2025 deliveries

A look at Tesla China’s order page as of writing shows that the earliest deliveries for the Model Y L, if ordered today, would be October 2025 instead. This suggests that the six-seat Model Y variant has effectively been sold out for September. This bodes well for the vehicle, and it suggests that it is a variant that may be able to raise Tesla’s sales numbers in China, as well as territories where the Model Y L could be exported.

Rumors of the Model Y L’s strong sales have been abounding. After the vehicle’s launch, industry watchers estimated that Tesla China has received over 35,000 orders for the Model Y L in just one day. Later estimates suggested that the Model Y L’s orders have breached the 50,000 mark.

Starship Flight 10 rescheduled as SpaceX targets Monday launch

SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

SpaceX stood down from its planned Starship Flight 10 on Sunday evening, citing an issue with ground systems. 

The launch attempt was scheduled during a one-hour window that opened at 7:30 p.m. ET, but it was called off just 17 minutes before the window opened. SpaceX said it is now targeting Monday evening for Starship’s 10th flight test.

Flight 10 rescheduled

A lot of excitement was palpable during the lead up to Starship Flight 10’s first launch window. After the failures of Starship Flight 9, many were interested to see if SpaceX would be able to nail its mission objectives this time around. Starship itself seemed ready to fly, with the upper stage being loaded with propellant as scheduled. Later on, SpaceX also noted that Starship’s Super Heavy booster was also being loaded with propellant.

However, 17 before the launch window opened, SpaceX noted that it was “standing down from today’s tenth flight of Starship to allow time to troubleshoot an issue with ground systems.” Elon Musk, in a post on X, further clarified that a “ground side liquid oxygen leak needs to be fixed.” Musk did state that SpaceX will attempt Flight 10 again on Monday, August 25, 2025.

Starship and SpaceX’s development goals

The fully integrated Starship system is the tallest and most powerful rocket ever built, standing over 400 feet when stacked. Composed of the reusable Super Heavy booster and the Starship upper stage, the vehicle is central to SpaceX’s long-term ambitions of lunar and Martian missions. NASA has already selected Starship as the crewed lunar lander for Artemis, with its first astronaut landing mission tentatively set for 2027, as noted in a Space.com report.

So far, Starship has flown nine times from Starbase in Texas, with three launches this year alone. Each flight has offered critical data, though all three 2025 missions encountered notable failures. Flight 7 and Flight 8 ended in explosions less than 10 minutes after launch, while Flight 9 broke apart during reentry. Despite setbacks, SpaceX has continued refining Starship’s hardware and operations with each attempt. Needless to say, a successful Flight 10 would be a significant win for the Starship program.
