The European Space Agency (ESA) has published an unusual press release – in the form of a Twitter thread – specifically blaming SpaceX’s nascent Starlink constellation for a collision avoidance maneuver recently performed by Aeolus, a scientific spacecraft in low Earth orbit (LEO). SpaceX reportedly refused to move its Starlink satellite, triggering the maneuver.

SpaceX launched an extensive Starlink beta test on May 23rd, 2019, placing an unprecedented 60 satellites in LEO. Discussed earlier today on Teslarati, 50 of those 60 satellite prototypes have reached their final 550 km (340 mi) orbits and are functioning as intended, while 5 have paused their orbit-raising, 3 have been declared dead, and 2 are intentionally lowering their orbits as an end-of-life simulation.

Update: SpaceX has released an official statement on the matter.

“Our Starlink team last exchanged an email with the Aeolus operations team on August 28, when the probability of collision was only in the 2.2e-5 range (or 1 in 50k), well below the 1e-4 (or 1 in 10k) industry standard threshold and 75 times lower than the final estimate. At that point, both SpaceX and ESA determined a maneuver was not necessary. Then, the U.S. Air Force’s updates showed the probability increased to 1.69e-3 (or more than 1 in 10k) but a bug in our on-call paging system prevented the Starlink operator from seeing the follow on correspondence on this probability increase – SpaceX is still investigating the issue and will implement corrective actions. However, had the Starlink operator seen the correspondence, we would have coordinated with ESA to determine best approach with their continuing with their maneuver or our performing a maneuver.”

–SpaceX, 09/03/2019

Additionally, Starlink satellites have already reportedly performed 16 autonomous collision avoidance maneuvers (sans human operator interference) and SpaceX confirmed that the satellite ESA was worried about is fully operational while it continues its deorbit maneuver.


On one hand, ESA’s description of events is bizarre and dubious, at points. ESA Operations tweeted that “it is very rare to perform collision avoidance maneuvers with active satellites”, while the very next tweet stated that “ESA performed 28 collision avoidance maneuvers [in 2018]”, meaning that the procedure is roughly biweekly for ESA alone.

Meanwhile, Matt Desch – CEO of Iridium, the owner and operator of one of the largest LEO constellations ever flown – stated that its Iridium NEXT satellites perform similar maneuvers weekly, without the need to “put out a press release to say who [Iridium] maneuvered around”. In simple terms, collision avoidance maneuvers are extremely common and extremely routine and are a fundamental part of operating satellites on orbit – be it one, ten, or ten thousand.

However, spaceflight journalist Jonathan O’Callaghan was told by sources in ESA that the space agency had directly contacted SpaceX with concerns about a possible Starlink-Aeolus collision and the company refused to move their spacecraft in cooperation. This left ESA’s Aeolus to perform the maneuver.

From the perspective of O’Callaghan’s sourced information, SpaceX certainly appears to be in the wrong in this case. However, the current story is extremely patchy, and more information is needed to paint a true-to-life picture of events. Was SpaceX’s refusal to move based on an inability to move one of the two satellites it is intentionally deorbiting? Is the company simply confident in what it has described as a suite of autonomous collision avoidance hardware and software installed on each Starlink satellite?

Either way, if SpaceX actually is/was as terse and uncommunicative as O’Callaghan’s sources have painted the company, it is an extremely bad look. For SpaceX to successfully operate hundreds of Starlink satellites, let alone its constellation’s full ~11,800, good spaceflight stewardship and hand-in-hand cooperation with other major (and minor) operators is an absolute necessity. If SpaceX acts like the bully in the room and simply ignores or avoids cooperation and fails to take responsibility and help maintain current standards of collision avoidance, the company will very quickly find itself surrounded by newly made enemies like ESA.

Elon Musk sheds two new bits of detail on Starship after 13th test launch

Elon Musk shed two new bits of detail on Starship following its 13th test launch, which was an overwhelming success.

SpaceX launched Starship for the 13th time last Friday after two delays: one on Monday when several Raptor engines did not ignite, and another on Thursday due to unfavorable weather conditions in Starbase, Texas.

The launch was overwhelmingly successful. SpaceX was able to complete a necessary test of the heat shield tiles by increasing the acceleration of Starship from launch throughout the flight; 20 Starlink v3 satellites were released with no issue; the Super Heavy Booster landed safely in the Gulf of America, Ship successfully reignited engines while in space; and it also splashed down without incident in the Indian Ocean.

SpaceX Starship just nailed something it’s never done before

Nevertheless, more details are coming out about Starship, and Musk is doing the talking.

Starship Will Be Retrieved in the Ocean

Musk revealed on Tuesday night that Starship would be recovered by a ship in the Indian Ocean. SpaceX routinely tries to recover Starship after splashdown in an effort to find out more about the flight by examining the spacecraft afterward.

This helps engineers find out more about why things might have happened, allows them to examine any potential damage or anomalies that might have occurred, and increases the chances of an even more successful flight next time thanks to the additional information recovered.

Ship Could Have Been Caught by Tower Arms, Musk claims

Musk has already indicated that SpaceX will plan to attempt a catch of Starship with the 14th test flight. While this would be a major accomplishment, it would be an expected next step, considering the fact that the Super Heavy Booster has already been caught by the chopsticks on numerous occasions.

A ship catch would be a great indication of where SpaceX stands in terms of reusability and launch cadence. A successful catch with relatively no incidents would be a good sign that SpaceX is nearing a more frequent launch of Starship, but also that the reusability of the massive rocket would be something many would expect in the near future.

It is a necessity to make life multiplanetary.

Elon Musk updates the SpaceX timeline for Mars

Elon Musk has updated his timeline for when humans will walk on Mars and for when ships will simply get there.

The objective of getting to Mars has been one of Musk’s biggest goals since becoming a serial entrepreneur and realizing that time on Earth is limited. Musk has said several times he hopes to die on Mars, and not by impact.

Musk now believes that people will be on Mars in “roughly 5 to 7 years.” He said that a Mars lander will get there “a few years sooner.”

The response from Musk comes after NASA Administrator Jared Isaacman said that SpaceX’s biggest priority is the Moon and not Mars. Because of this, Isaacman conceded that he believes nuclear power and propulsion investments will provide “potentially the pathway with the fewest miracles required to put four people on Mars in the next 10 to 15 years.”

Of course, this is what NASA can do through taxpayer funding and nuclear investments, he added.

Musk’s grand ambitions are much more optimistic than most, and it is certainly a double-edged sword. This is not the first time timelines for Mars have been somewhat lofty, especially to those normal thinkers like you and me, not super geniuses like Musk.

SpaceX Board has set a Mars bonus for Elon Musk

In fact, the SpaceX and Tesla frontman has said on at least a dozen occasions that we could be on Mars in the coming years. Musk said 2020 would be the big year as early as 2009. In 2020, he was “highly confident” of a landing in 2026, and had even said 2024 in a best-case scenario.

The point is, the range has varied, and it’s anyone’s guess when we’ll get there. This latest adjustment to the timeline is typical of Musk, and while the Moon has seemingly taken priority over Mars, it is still worth mentioning that the ultimate goal is to make life multiplanetary, and it starts potentially with the Red Planet.

SpaceX gets an absolutely crazy price target after rough IPO

SpaceX (NASDAQ: SPCX) got an absolutely crazy price target rating from Raymond James after the company experienced a tough first few weeks following its Initial Public Offering (IPO).

Despite the tumultuous start, SpaceX has plenty of believers, and the company’s massively successful Starship launch last Friday, its 13th test flight of the massive rocket, went so smoothly that Raymond James analysts pushed its price target on the company to roughly 7 times its current trading level.

The firm officially put a “Strong Buy” rating and an $800 price target on the stock. It currently trades at around $113. Its all-time high is $225.64, reaching this trading level shortly after shares first went public.

Raymond James’ price target is tied to the firm’s confidence after Starship’s 13th test flight. Analysts at the firm said it was an incremental step that reduces engineering risks, citing the widely successful heat shield test that CEO Elon Musk recently detailed, the smooth deployment of Starlink V3 satellites, and a successful in-space engine relight.

SpaceX also managed to see Starship splash down safely in the Indian Ocean, while the Super Heavy Booster fell down to the Gulf of America with no incidents.

It is interesting to see these launches have such a tremendous impact on the stock and what investors think of it. After SpaceX initially delayed the Starship launch last week, shares fell tremendously. Most probably did not realize that the stand-down is a standard practice, especially if everything is not perfect.

The mission was initially aborted due to an issue with Raptor engines. This was resolved, and Starship launched last Friday after another delay on Thursday, which was caused by weather.

Now that analysts have seen what SpaceX launches are capable of and how impressive the feat is, firms are adjusting their price targets accordingly, making it known that they have high expectations for the space exploration company.
