SpaceX just delayed the launch debut of Falcon Heavy Block 5 by about an hour and a half to dodge bad high-altitude wind conditions that would be a risk to the vehicle during launch and to both side boosters during their subsequent landing attempts.

Falcon Heavy Flight 2’s evening launch window now sits at 8:00-8:32 pm ET (00:00-00:32 UTC), leaving little margin for any bugs prior to liftoff but still plenty of time for at least one serious attempt. Featuring three brand new Block 5 boosters, this mission also has the potential to redeem a slight anomaly that caused Falcon Heavy Flight 1’s center core to be destroyed during a recovery attempt. Both side boosters will return to SpaceX’s Cape Canaveral Landing Zones 1 and 2 (LZ-1/LZ-2), while the Block 5 center core will aim for drone ship Of Course I Still Love You (OCISLY) some 1000 km (~600 mi) distant in the Atlantic Ocean.

Weather in the Atlantic is currently about as good as could be expected, with minimal waves and low winds, excellent conditions for the safe recovery of Falcon Heavy’s center core – likely B1055 – and Version 2 payload fairing halves. Although fairing recovery vessel Mr. Steven is also out and about, the vessel will not be taking part in this launch’s recovery efforts after an anomaly earlier this year catastrophically damaged his arms and net, breaking two arms off and resulting in the loss of the net.

All other SpaceX vessels – GO Searcher, GO Navigator, tugboat Hollywood, and drone ship OCISLY – will, however, be directly involved in this recovery attempt. Navigator and Searcher are expected to focus on gathering data and extricating Falcon Heavy’s fairing halves – hopefully intact after parasailing gently onto the ocean surface – from the Atlantic.

During Falcon Heavy Flight 1, the rocket’s center core – B1032 – was destroyed when a failure to reignite its landing Merlin 1D engines resulted in the booster slamming into the ocean at more than 300 mph (~500 km/h). The impact was apparently so severe that it actually seriously damaged the OCISLY’s maneuvering thrusters despite the fact that it didn’t directly strike the drone ship. According to CEO Elon Musk, B1032 had run out of the TEA/TEB (triethylaluminum + triethylboron) fluid used to ignite its Merlin engines, although why the booster ran out of it prematurely is unknown.

Regardless, prior to December 2018, B1032 was the first failed SpaceX landing after dozens of successful attempts. In December, Falcon 9 B1051 suffered an unrelated failure with the hydraulic pump system that controls its titanium grid fins, causing the new Block 5 booster to land softly in the Atlantic Ocean, missing LZ-1 by a few miles. Since the first successful Falcon 9 land-based and sea-based recoveries in December 2015 and April 2016 respectively, SpaceX has landed Falcon 9 and Heavy boosters 35 times with one complete failure (Falcon Heavy, B1032) and one partial failure (Falcon 9, B1051).

If all goes as planned during Falcon Heavy Flight 2, SpaceX will have successfully returned boosters to its East Coast landing zones after more than 14 months of inactivity, landed a Falcon Heavy center core for the first time ever, and recovered three boosters nearly simultaneously after a single launch – also for the first time. Falcon Heavy’s third launch could happen as early as June 2019 – two months from now – if everything is safely recovery.

SpaceX’s launch livestream will go live approximately 20 minutes before liftoff, currently scheduled for no earlier than 8pm ET (00:00 UTC, April 11).

SpaceX secures win as US labor board drops oversight case

The NLRB confirmed that it no longer has jurisdiction over SpaceX.

SpaceX scored a legal victory after the National Labor Relations Board (NLRB) decided to dismiss a case which accused the company of terminating engineers who were involved in an open letter against founder Elon Musk. 

The NLRB confirmed that it no longer has jurisdiction over SpaceX. The update was initially shared by Bloomberg News, which cited a letter about the matter it reportedly reviewed.

In a letter to the former employees’ lawyers, the labor board stated that the affected employees were under the jurisdiction of the National Mediation Board (NMB), not the NLRB. As a result, the labor board stated that it was dismissing the case.

As per Danielle Pierce, a regional director of the agency, “the National Labor Relations Board lacks jurisdiction over the Employer and, therefore, I am dismissing your charge.”

The NMB typically oversees airlines and railroads. The NLRB, on the other hand, covers most private-sector employers, as well as manufacturers such as Boeing. 

The former SpaceX engineers have argued that the private space company did not belong under the NMB’s jurisdiction because SpaceX only offers services to “hand-picked customers.” 

In an opinion, however, the NMB stated that SpaceX was under its jurisdiction because “space transport includes air travel” to get to outer space. The mediation board also noted that anyone can contact SpaceX to secure its services.

SpaceX had previously challenged the NLRB’s authority in court, arguing that the agency’s structure was unconstitutional. Jennifer Abruzzo, the NLRB general counsel under former United States President Joe Biden, rejected SpaceX’s claims. Following Abruzzo’s termination under the Trump administration, however, SpaceX asked the labor board to reconsider its arguments.

SpaceX is not the only company that has challenged the constitutionality of the NLRB. Since SpaceX filed its legal challenge against the agency in 2024, other high-profile companies have followed suit. These include Amazon, which has filed similar cases that are now pending.

SpaceX blocks unauthorized Starlink terminals used by Russian troops

Ukrainian officials confirmed that Starlink terminals believed to be used by Russian troops were disabled after coordination with SpaceX.

SpaceX has taken steps to block unauthorized use of its Starlink satellite internet network, a move Ukrainian officials stated is already disrupting Russian military communications. 

Russian units lose a key communications tool

As per a report from The Guardian, Ukrainian defense officials have confirmed that Starlink terminals believed to be used by Russian troops were recently disabled after coordination with SpaceX. The move reportedly affected frontline communications and drone operations, especially in areas where traditional military radios are unreliable or easily jammed.

For months, Russian units had relied on large numbers of illicitly obtained Starlink terminals to stay connected along the front. The satellite internet service allowed faster coordination and more precise drone use for Russian forces.

Several Russian military bloggers close to frontline units have acknowledged the impact of the Starlink shutdown, with some describing sudden connectivity problems in the satellite internet service.

Russia lacks comparable replacement

Russia does not have a satellite internet system that matches Starlink’s speed, coverage, and ease of deployment. Alternatives such as fiber-optic lines, short-range wireless links, and digital radio systems take longer to install and work inadequately for fast-moving units.

Russia does operate limited satellite communications through state-linked providers, but those systems rely mainly on geostationary satellites, which are notably slower. Coverage is uneven, and data capacity is far lower than Starlink’s low-Earth-orbit network.

For now, Ukraine has stated that it has introduced a verification system that allows only approved Starlink terminals to connect. Devices believed to be linked to Russian forces are blocked from the network. That being said, Ukrainian officials have also claimed Russian units are trying to work around the restrictions by asking civilians to register Starlink terminals in their names.

Elon Musk pivots SpaceX plans to Moon base before Mars

The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.

Elon Musk has clarified that SpaceX is prioritizing the Moon over Mars as the fastest path to establishing a self-growing off-world civilization. 

The shift, Musk explained, is driven by launch cadence and the urgency of securing humanity’s long-term survival beyond Earth, among others.

Why the Moon is now SpaceX’s priority

In a series of posts on X, Elon Musk stated that SpaceX is focusing on building a self-growing city on the Moon because it can be achieved significantly faster than a comparable settlement on Mars. As per Musk, a Moon city could possibly be completed in under 10 years, while a similar settlement on Mars would likely require more than 20.

“For those unaware, SpaceX has already shifted focus to building a self-growing city on the Moon, as we can potentially achieve that in less than 10 years, whereas Mars would take 20+ years. The mission of SpaceX remains the same: extend consciousness and life as we know it to the stars,” Musk wrote in a post on X.

Musk highlighted that launch windows to Mars only open roughly every 26 months, with a six-month transit time, whereas missions to the Moon can launch approximately every 10 days and arrive in about two days. That difference, Musk stated, allows SpaceX to iterate far more rapidly on infrastructure, logistics, and survival systems.

“The critical path to a self-growing Moon city is faster,” Musk noted in a follow-up post.

Mars still matters, but runs in parallel

Despite the pivot to the Moon, Musk stressed that SpaceX has not abandoned Mars. Instead, Mars development is expected to begin in about five to seven years and proceed alongside the company’s lunar efforts.

Musk explained that SpaceX would continue launching directly from Earth to Mars when possible, rather than routing missions through the Moon, citing limited fuel availability on the lunar surface. The Moon’s role, he stated, is not as a staging point for Mars, but as the fastest achievable location for a self-sustaining off-world civilization.

“The Moon would establish a foothold beyond Earth quickly, to protect life against risk of a natural or manmade disaster on Earth,” Musk wrote.
