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).

Elon Musk has revealed SpaceX’s target timeline for the next Starship launch, which will be the tenth in program history.

Musk says SpaceX is aiming for a timeline of roughly three weeks from now, which would come about ten weeks after the previous launch.

Coincidentally, it would bring the two launches 69 days apart, and if you know anything about Elon Musk, that would be an ideal timeline between two launches.

SpaceX is coming off a test flight in which it lost both the Super Heavy Booster and the Upper Stage in the previous launch. The Super Heavy Booster was lost six minutes and sixteen seconds into the flight, while SpaceX lost communication with the Ship at 46 minutes and 48 seconds.

Musk is aiming for the tenth test flight to take place in early August, he revealed on X:

This will be SpaceX’s fourth test flight of the Starship program in 2025, with each of the previous three flights bringing varying results.

IFT-7 in January brought SpaceX its second successful catch of the Super Heavy Booster in the chopstick arms of the launch tower. The ship was lost after exploding during its ascent over the Turks and Caicos Islands.

IFT-8 was on March 6, and SpaceX caught the booster once again, but the Upper Stage was once again lost.

The most recent flight, IFT-9, took place on May 27 and featured the first reused Super Heavy Booster. However, both the Booster and Upper Stage were lost.

The Federal Aviation Administration (FAA) hit SpaceX with a mishap investigation for Flight 9 on May 30.

NASA and SpaceX are targeting July 31 for the launch of Crew-11, the next crewed mission to the International Space Station (ISS). The flight will lift off from Launch Complex 39A at Kennedy Space Center in Florida, using the Crew Dragon Endeavour and a Falcon 9 booster.

Crew Dragon Endeavour returns

Crew-11 will be the sixth flight for Endeavour, making it SpaceX’s most experienced crew vehicle to date. According to SpaceX’s director of Dragon mission management, Sarah Walker, Endeavour has already carried 18 astronauts representing eight countries since its first mission with NASA’s Bob Behnken and Doug Hurley in 2020, as noted in an MSN report.

“This Dragon spacecraft has successfully flown 18 crew members representing eight countries to space already, starting with (NASA astronauts) Bob (Behnken) and Doug (Hurley) in 2020, when it returned human spaceflight capabilities to the United States for the first time since the shuttle retired in July of 2011,” Walker said.

For this mission, Endeavour will debut SpaceX’s upgraded drogue 3.1 parachutes, designed to further enhance reentry safety. The parachutes are part of SpaceX’s ongoing improvements to its human-rated spacecraft, and Crew-11 will serve as their first operational test.

The Falcon 9 booster supporting this launch is core B1094, which has launched in two previous Starlink missions, as well as the private Ax-4 mission on June 25, as noted in a Space.com report.

The four-members of Crew-11 are NASA astronauts Zena Cardman and Mike Fincke, as well as Japan’s Kimiya Yui and Russia’s Oleg Platonov.

Tight launch timing

Crew-11 is slated to arrive at the ISS just as NASA coordinates a sequence of missions, including the departure of Crew-10 and the arrival of SpaceX’s CRS-33 mission. NASA’s Bill Spetch emphasized the need for careful planning amid limited launch resources, noting the importance of maintaining station altitude and resupply cadence.

“Providing multiple methods for us to maintain the station altitude is critically important as we continue to operate and get the most use out of our limited launch resources that we do have. We’re really looking forward to demonstrating that capability with (CRS-33) showing up after we get through the Crew-11 and Crew-10 handover,” Spetch stated.

SpaceX launched the Falcon 9 rocket kickstarting Axiom Space’s Ax-4 mission to the International Space Station (ISS). Axiom’s Ax-4 mission is led by a historic international crew and lifted off from Kennedy Space Center’s Launch Complex 39A at 2:31 a.m. ET on June 25, 2025.

The Ax-4 crew is set to dock with the ISS around 7 a.m. ET on Thursday, June 26, 2025. Axiom Space, a Houston-based commercial space company, coordinated the mission with SpaceX for transportation and NASA for ISS access, with support from the European Space Agency and the astronauts’ governments.

The Ax-4 mission marks a milestone in global space collaboration. The Ax-4 crew, commanded by U.S. astronaut Peggy Whitson, includes Shubhanshu Shukla from India as the pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary.

“The trip marks the return to human spaceflight for those countries — their first government-sponsored flights in more than 40 years,” Axiom noted.

Shukla’s participation aligns with India’s Gaganyaan program planned for 2027. He is the first Indian astronaut to visit the ISS since Rakesh Sharma in 1984.

Axiom’s Ax-4 mission marks SpaceX’s 18th human spaceflight. The mission employs a Crew Dragon capsule atop a Falcon 9 rocket, designed with a launch escape system and “two-fault tolerant” for enhanced safety. The Axiom mission faced a few delays due to weather, a Falcon 9 leak, and an ISS Zvezda module leak investigation by NASA and Roscosmos before the recent successful launch.

As the crew prepares to execute its scientific objectives, SpaceX’s Ax-4 mission paves the way for a new era of inclusive space research, inspiring future generations and solidifying collaborative ties in the cosmos. During the Ax-4 crew’s 14-day stay in the ISS, the astronauts will conduct nearly 60 experiments.

“We’ll be conducting research that spans biology, material, and physical sciences as well as technology demonstrations,” said Whitson. “We’ll also be engaging with students around the world, sharing our experience and inspiring the next generation of explorers.”

SpaceX’s Ax-4 mission highlights Axiom’s role in advancing commercial spaceflight and fostering international partnerships. The mission strengthens global space exploration efforts by enabling historic spaceflight returns for India, Poland, and Hungary.
