Launch Roundup: Relativity Space & JAXA to Launch New Rockets, SpaceX Supply Ship Headed to Space Station

Relativity Space and the Japan Aerospace Exploration Agency (JAXA) will attempt to launch new boosters while SpaceX sends a resupply ship to the International Space Station (ISS) this week.
Relativity Space is set to launch Terran 1, the world’s first 3D printed rocket, from Cape Canaveral Space Force Station on Wednesday, March 8. The new booster will not carry a payload during the flight test.
Launch Time: 1 p.m. EST (18:00 UTC)

Terran 1 stands 33.5 m (110 ft.) tall and is powered by nine first stage Aeon engines and one second stage Aeon engine that use liquid oxygen and liquid natural gas. The rocket has the following payload capacities:
- Low Earth orbit: 1,250 kg (2,756 lb) to 185 km (115 miles)
- Sun synchronous orbit: 900 kg (1,984 lb) to 500 km (311 miles)
- Sun synchronous orbit: 700 kg (1,534 lb) to 1,200 km (746 miles).
Relativity Space is advertising dedicated launches at $12 million apiece.

JAXA will attempt to launch its new H3 rocket for the second time on March 7 after the booster suffered an abort on Feb. 17. The launcher will carry the ALOS-3 Earth observation satellite.
Launch Window: 8:37:55:55-8:44:15 p.m. EST on Monday, March 6 (01:37:55-01:44:15 UTC on Tuesday, March 7)

JAXA said the abort last month was caused by an abnormality in the power supply system of the first-stage engines. The flight control software shut down the engines after they began to fire and before signals were sent to two solid rocket boosters to fire.
H3 is designed to replace the H-IIA and already retired H-IIB boosters. The launch vehicle has a capacity of placing 4,000 kg (8,818 lb) into sun synchronous orbit (SSO) or 4,000–7,900 kg (8,818–17,417 lb) into geostationary transfer orbit.
SpaceX has two Falcon 9 launches scheduled this week. The first flight will launch 40 broadband satellites for OneWeb.
Launch Time: 2:05 p.m. EST (19:05 UTC) on Thursday, March 9

SpaceX’s second launch will see a Falcon 9 launch a Cargo Dragon spacecraft to ISS.
Launch Time: 8:36 p.m. on Saturday, March 11 (01:36 UTC on Sunday, March 12)

The launch will also include three CubeSats:
- ARKSat-1 – University of Arkansas – technology demonstration
- LightCube – Arizona State University – education
- SNoOPI – Purdue University School of Aeronautics and Astronautics – technology demonstration.
Russian and China also have launches scheduled this week.
Last Week in Launches
Last week belonged entirely to SpaceX as Elon Musk’s company launched a new crew to the International Space Station and 72 Starlink broadband satellites aboard three Falcon 9 rockets from different coasts.
Week in Launches
Feb. 27-March 5
Date | Launcher – Organization | Payload – Organization | Purpose | Launch Site |
---|---|---|---|---|
Feb. 27 | Falcon 9 – SpaceX | 21 Starlink V2 – SpaceX | Communications | Cape Canaveral |
March 2 | Falcon 9 – SpaceX | Crew Dragon – SpaceX | ISS Crew | Kennedy |
March 3 | Falcon 9 – SpaceX | 51 Starlink – SpaceX | Communications | Vandenberg |
SpaceX’s launch of the 21 Starlink V2 Minis represented a major advance for the company’s global broadband service.
“V2 minis include key technologies—such as more powerful phased array antennas and the use of E-band for backhaul—which will allow Starlink to provide ~4x more capacity per satellite than earlier iterations,” SpaceX tweeted. “This means Starlink can provide more bandwidth with increased reliability and connect millions of more people around the world with high-speed internet.”
V2 minis also include Hall thrusters powered by argon.
“Developed by SpaceX engineers, they have 2.4x the thrust and 1.5x the specific impulse of our first gen thrusters,” the company tweeted. “This will also be the first time ever that argon Hall thrusters are operated in space.”
The launch of the V2 minis raised the number of Starlink satellites over 4,000. The company has launched 4,052

Korean Innospace will attempt again the first launch of its HANBIT-TLV rocket from Alcântara Launch Center, Brazil.
I find it interesting that despite its location Alcântara Space Center has not attracted customers for launching comsats which illustrates the importance of having a good climate for business. It is currently ranked 124 out of 190 nations in terms of doing business due to its complex regulatory environment.
Tell that to the World Bank, an UN Agency, who published the list. BTW, the USA is 6th on their list.
I think there is more than one reason for this and one of them could be, in fact, the Brazilian bureaucracy and the legal uncertainty that changes according to the winds of politics.
Targeting today, March 7th, for first launch attempt, time pending the weather conditions.
Unfortunately, as said last year by Innospace, brazilian air force that runs the base don’t will allow livestream of the launch. ?
H3 launch failure today. Liftoff good. Second stage engine ignition failure.

Yeah, I was watching that too. Tough luck for JAXA and Mitsubishi. But brand-new rockets don’t exactly have a sterling record of initial successes. And even the ones that succeed the first time out have not proven immune to later failures early in their launch histories.
The Japanese will get H-3 right at some point. But where that point will be is the question. Among the knock-on effects of this H-3 failure is that the years-late debut mission of HTV-X to ISS will almost certainly be delayed still further.
What a sad contrast to the Hat Trick that JAXA pulled off with the first launch of H-IIB launch vehicle.

It appears that China is looking for a way to shoot down Starlink satellites in the future since they are being used by the military in the Ukrainian war. This of course is the danger when a civilian system is used in war.

Studying Ukraine war, China’s military minds fret over US missiles, Starlink

The PRC mandarins would do well to recall what followed in the wake of Russians actually spitting on Elon Musk back around the turn of the century. The last thing a tottering PRC needs is to get Elon Musk seriously contemplating what he can do to protect as well as deploy his Starlink constellation. Messing with the U.S. DoD is one thing. Messing with Tony Stark is quite another.
