SpaceX recently provided NASA with the third known official render of its stainless steel Starship, focused on the vehicle’s potential utility for launching massive scientific spacecraft for NASA. Starship’s only direct competition for the proposed LUVOIR telescope: NASA’s own SLS rocket.

Published by NASA’s Goddard Space Flight Center (GSFC), Starship is shown with a smaller “B” variant of the proposed LUVOIR space telescope in its payload bay. According to a scientist from the Space Telescope Science Institute (STSI), the massive LUVOIR-A variant could “barely” fit inside Starship’s clamshell bay, but the telescope could also be tweaked to more perfectly fit the constraints of its chosen launch vehicle. LUVOIR is effectively being designed as a logical follow-up to the James Webb Space Telescope (JWST) and could be ready to launch no earlier than 2039 if NASA selects the idea – one of three under consideration – for future development.

The LUVOIR telescope (shorthand for Large UV/Optical/IR Surveyor) is currently grouped into two different categories, A and B. A is a full-scale, uncompromised telescope with a vast 15-meter primary mirror and a sunshade with an area anywhere from 5000 to 20000 square meters (1-4 acres). B is a smaller take on the broadband surveyor telescope, with an 8-meter primary mirror (a quarter of the area of LUVOIR-A’s) accompanied by a similarly reduced sunshade (and price tag, presumably).

— Teslarati, July 2018

Goddard’s “we asked, SpaceX checked” statement refers to a funded analysis of LUVOIR launch options the group announced back in July 2018, at which point the future prospects of NASA’s SLS rocket were far more stable. Approximately nine months later, NASA administrator Jim Bridenstine announced that all work on future SLS upgrades – including the Block 1B and Block 2 variants that could have supported the launch of LUVOIR-A – was to be halted as soon as possible. All of that funding would instead be focused on mitigating a never-ending string of delays and pushing SLS to actually prepare for its first launches. Bridenstine has since publicly waffled on that aggressive plan, simultaneously indicating that some of those SLS upgrades (mainly an advanced upper stage, EUS) would be critical for one variant of his proposal to return astronauts to the Moon as early as 2024.

Regardless, the blood of SLS is currently in the water as NASA pursues an answer to the question of whether commercial rockets can instead be used to launch the agency’s Orion spacecraft and Lunar Gateway segments. Based on preliminary interviews focused on NASA’s internal study of the subject, there is still plenty of room for SLS as long as its contractors (namely Boeing) can stem relentless delays, cost overruns, and quality control issues and finally prepare the rocket for its first missions.

As described above, it appears likely that NASA is going to require the SLS rocket’s core stage to conduct a critical mission-duration test fire before permitting the vehicle to begin launch preparations in Florida. As a result, there will be almost no conceivable way for the rocket to rise to the 2020 launch debut challenge issued by Bridenstine, potentially meaning that NASA will put significant resources into studying and developing alternatives to SLS. If or when NASA sets the precedent for allowing serious studies and funding of SLS alternatives, the death of the rocket will almost certainly be assured. Relative to commercial rockets like Falcon Heavy, New Glenn, Vulcan Heavy, and even SpaceX’s BFR (i.e. Starship/Super Heavy), conservative estimates suggest that SLS will be no less than 5-20+ times as expensive on a per-launch basis.

Consequently, it should come as no surprise to see NASA Goddard openly confirm its willingness to launch future flagship science missions on SpaceX’s Starship vehicle, so long as the rocket is successfully developed, launched, and certified by NASA for high-value missions. Given just how distant the proposed ~2039 launch of LUVOIR is and how early SpaceX is in the process of developing Starship/Super Heavy into a highly mature and reliable launch vehicle, one should not read too far into Goddard’s public support.

However, there should be no doubt at this point that SpaceX’s next-generation Starship and current-generation Falcon Heavy rockets are already upsetting certain aspects of the status quo. If SpaceX continues to refine Starship’s design and demonstrate Falcon Heavy’s reliability and readiness, studies like Goddard’s LUVOIR launch case can be expected to crop up throughout domestic and global space industries, both pubic and private.

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.

Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.

A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.

The company said that a fire developed in the aft section of Starship:

“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”

Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.

The leak was evidently large enough to build more pressure than the vent was able to handle:

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:

There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.

“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.

The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.

Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.

SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.

For now, SpaceX is extremely selective as to when it attempts catches.

However, it was successful during this attempt, its second completed catch:

This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.

These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.

Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.

It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.

We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”

The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.

What’s new with this Starship launch

With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.

First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”

SpaceX eyes 25 annual Starship launches starting next year

There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.

Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.

Starlink test

SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”

Ship return and catch

There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”

The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.

Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
