SpaceX’s Falcon Heavy Block 5 launch debut moved to April 10 to skip storms

Published

SpaceX has decided to move Falcon Heavy’s commercial launch debut 24 hours to the right – from April 9 to 10 – to account for minor processing delays and dodge an unusually severe weather system currently active on the East Coast.

The giant rocket – flying for the first time in its Block 5 configuration – is now scheduled to lift off no earlier than (NET) 6:35 pm EDT (22:35 UTC) on Wednesday, April 10th. This minor delay has been more or less expected by close observers since Falcon Heavy Flight 2’s static fire test was pushed from March 31st to April 5th and is not a cause for concern. Instead, these fairly routine minor slips indicate that the rocket is flowing surprisingly smoothly towards its first commercial launch. In fact, launching on April 10th – five days after a static fire on April 5th – would be routine for Falcon 9, let alone a rocket with three Falcon 9 boosters.

In other words, these minor slips indicate that SpaceX has already managed to more or less transfer its growing experience and confidence with Falcon 9 Block 5 into its brand new Falcon Heavy Block 5 variant. Despite the fact that Falcon Heavy effectively has twice as many major components (three boosters and an upper stage vs. one booster and an upper stage) and uses a center core that is in many ways an entirely different rocket from Falcon 9, the Block 5 rocket’s first launch flow is proceeding as smoothly as SpaceX’s average Falcon 9 flow.

Those average flows typically take 24-48 hours to roll out to the pad and conduct a static fire, followed by an additional 24 or so hours before returning to the hangar. Excluding a few outliers, Falcon 9 Block 5 has typically required four to five days of processing between static fire and the first launch attempt, while the best and worst flows range from 3-10 days. If an observer was unaware that Falcon Heavy was launching, the rocket’s Flight 2 flow would thus be hard to distinguish from its far simpler brethren, suggesting that SpaceX learned a great deal from Falcon Heavy Flight 1 and has been able to communication almost all of the benefits of Block 5 to the triple-booster rocket.

SpaceX can thus retain its exceptionally efficient rocket processing backend, requiring minimal disruption to the rest of its Falcon 9 launch infrastructure and only minor modifications to dual-use hardware and facilities like Pad 39A’s transporter/erector (T/E) and main hangar. In fact, a single-core Falcon 9 booster – B1051 from Crew Dragon’s launch debut – can be seen in the background of Falcon Heavy’s processing, simultaneously undergoing refurbishment and checkouts before it ships West to Vandenberg Air Force Base.

It’s a small detail – both literally and figuratively – but it illustrates that Falcon Heavy integration is already routine enough that there is no need to suspend unrelated activities happening quite literally in the same room. As SpaceX continues to somewhat regularly launch Falcon Heavy, this routinization is likely to continually improve, particularly once the company begins to reuse Falcon Heavy boosters. The first Falcon Heavy-specific booster reuse is scheduled to occur as few as two months after the launch of Arabsat 6A for a USAF mission known as Space Test Program 2 (STP-2).

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX is ready to bring home Butch Wilmore and Suni Williams, the two astronauts that have been stranded on the International Space Station (ISS) for nine months.

Last week, SpaceX launched its Crew-10 mission, which would dock onto the ISS late Saturday night and be the two astronauts’ ride home. Now, the end is in sight, and it appears both NASA and SpaceX are planning to have the two home this week, perhaps earlier than expected.

SpaceX readies to rescue astronauts from International Space Station

The agency and the company have announced that Dragon will autonomously undock from the ISS on Tuesday at 1:05 a.m. ET and should re-enter Earth’s atmosphere and splashdown off the Florida coast about 17 hours later.

SpaceX said:

“SpaceX and NASA are targeting Tuesday, March 18 at 1:05 a.m. ET for Dragon to autonomously undock from the International Space Station. After performing a series of departure burns to move away from the space station, Dragon will conduct multiple orbit-lowering maneuvers, jettison the trunk, and re-enter Earth’s atmosphere for splashdown off the coast of Florida approximately 17 hours later the same day.”

Crew-9 astronaut Nick Hague will be alongside Williams and Wilmore on the flight home, along with Roscosmos cosmonaut Aleksandr Gorbunov. Hague and Gorbunov have been in space since Saturday, September 28.

SpaceX was tasked with bringing Wilmore and Williams home after the Boeing Starliner that sent them there was determined not to be suitable for their return.

A report from the New York Post in late August said that Boeing employees routinely made fun of SpaceX workers, only for the company to bail them out:

SpaceX bails out Boeing and employees are reportedly ‘humiliated’

Crew-10 will bring the astronauts home, ending an extensive and unscheduled stay in space.

SpaceX readies to rescue astronauts from International Space Station

SpaceX is readying to launch the Crew-10 mission this evening, which will bring home U.S. astronauts Butch Wilmore and Suni Williams, who have been stuck on the International Space Station for nine months.

SpaceX is working alongside NASA to bring the two astronauts home, and all systems and weather conditions are looking ideal to launch the mission this evening from the Kennedy Space Center in Florida.

Boeing was originally tasked with the rescue mission.

The company sent a Starliner aircraft to the ISS in late September in an effort to bring Williams and Wilmore home. However, malfunctioning thrusters and other issues on the Starliner aircraft prevented NASA from giving the green light to the astronauts to board and come home.

SpaceX was then tasked with bringing the two home, and it appears they will be on their way shortly.

The launch was intended to occur on Wednesday, but a last-minute problem with the rocket’s ground systems forced SpaceX and NASA to delay until at least Friday. Things are looking more ideal for a launch this evening.

The launch is targeted for 7:03 p.m. ET, but another backup opportunity is available tomorrow, March 15, at 6:41 p.m.

SpaceX writes about the Dragon spacecraft that will be used for the mission:

“The Dragon spacecraft supporting this mission previously flew NASA’s Crew-3, Crew-5, and Crew-7 missions to and from the space station. This will be the second flight for the first stage booster supporting this mission, which previously launched the SES 03b mPOWER-e mission. Following stage separation, Falcon 9’s first stage will land on Landing Zone 1 (LZ-1) at Cape Canaveral Space Force Station.”

The mission will not only aim to bring the two astronauts who have been stranded for nine months home, but it will also conduct new research to prepare for human exploration beyond low-Earth orbit.

If Crew-10 launches at the planned time this evening, it will dock to the ISS at 11:30 p.m. ET on Saturday night.

Texas Governor Greg Abbott announced Wednesday that SpaceX has received a $17.3 million grant from the Texas Semiconductor Innovation Fund. The grant will be used to expand SpaceX’s Bastrop complex. 

SpaceX’s Bastrop complex is headlined by its Starlink factory, which is currently capable of producing 15,000 dishes per day, as per a video published by the private space company on social media platform X.

The Grant

The investment is expected to develop SpaceX’s semiconductor research and development (R&D) and advanced packaging facility in Bastrop. The expansion is expected to create over 400 jobs and over $280 million in capital investment, as per a press release from the Office of the Texas Governor.

Bastrop’s Planned Expansion

SpaceX plans to grow its Bastrop site by one million square feet over the next three years, focusing on Starlink kit production, including advanced silicon components. The proposed project includes printed circuit boards (PCBs), a semiconductor failure analysis lab, and advanced packaging for panel level packaging (PLP). Once complete, SpaceX’s Bastrop facility will stand as the largest PCB and PLP facility in North America.

What They Are Saying

SpaceX President Gwynne Shotwell shared her appreciation for Texas’ support, saying, “Incredible innovation and high-tech manufacturing is happening in Texas as a direct result of Governor Abbott’s leadership and the Texas Semiconductor Innovation Fund initiative. We love Texas. SpaceX is investing hundreds of millions of dollars into our Bastrop facility. This grant will help continue to expand Bastrop’s manufacturing for Starlink to help connect even more people across the state and around the world with high-speed, low-latency internet.”
