SpaceX preps for Cargo Dragon, Falcon Heavy launches despite setbacks

Published

on

Despite suffering the loss of the first Falcon Heavy Block 5 center core and a catastrophic failure of the first flight-proven Crew Dragon spacecraft in nearly the same week, SpaceX’s core operations continue as usual to prepare for multiple launches in the coming months.

The echoes of the past week’s failures and ‘anomalies’ will undoubtedly ring for months to come but SpaceX now finds itself in a unique situation. Despite the imminent start of a major failure investigation, it appears unlikely – at least for the time being – that it will impact the majority of Falcon 9 and Falcon Heavy launches planned for the rest of 2019. Currently on the Q2 2019 manifest are Cargo Dragon’s 17th operational mission (CRS-17), the first operational Starlink launch, Spacecom’s Amos-17 satellite, the Canadian Radarsat Constellation Mission (RCM), and Falcon Heavy’s third launch (STP-2).

Spotted on April 20th, this Falcon upper stage is most likely bound for the launch of either Starlink-1 or Amos-17.

Cargo Dragon – CRS-17

Following an April 20th explosion that destroyed Crew Dragon C201, SpaceX’s next launch – Cargo Dragon CRS-17 – has likely just become the most important in the near-term. Although Crew Dragon shares almost nothing directly in common with Cargo Dragon, both spacecraft still do come from the same lineage, relying on the same propellant and Draco maneuvering thrusters, as well as similar plumbing (excluding SuperDraco pods) and many of the same engineers and technicians.

On the other hand, Cargo Dragon has never suffered a catastrophic anomaly on the ground or in flight, although SpaceX has dealt with a fair share of less serious issues throughout the spacecraft’s operational life. Further, following the August 2017 launch of CRS-12, every CRS mission has launched with a flight-proven Cargo Dragon spacecraft. In fact, it’s quite likely that the CRS-12 Cargo Dragon capsule is the same spacecraft that has been refurbished for CRS-17, as it is currently the only flightworthy capsule to have only flown one orbital resupply mission.

It’s unclear which Falcon 9 booster has been assigned to CRS-17. NASA’s agreement with SpaceX for flight-proven boosters has been predicated on keeping those boosters ‘in-family’, so to speak, meaning that NASA will only accept flight-proven boosters if they have only flown NASA missions. The only booster that currently fits that bill is B1051, previously flown during Crew Dragon’s orbital launch debut on March 2nd, but B1051 has reportedly been assigned to SpaceX’s second Vandenberg launch of 2019 at the customer’s request. CRS-17 will thus likely launch on a new Falcon 9 booster (B1056). There is a chance that Crew Dragon’s catastrophic failure has severely contaminated the Landing Zone area with unburnt MMH and NTO, both of which are extraordinarily toxic to humans in even the tiniest of quantities.

Some launch-related questions may be answered in a NASA media briefing planned for 11am EDT, April 22nd. CRS-17 is scheduled to launch no earlier than 4:22 am EDT (08:22 UTC), April 30th.

Starlink, Falcon Heavy, and more

Meanwhile, the Falcon upper/second stage (S2) spotted in the tweet at the top of the article serves as evidence of preparations for launches planned in May/June, as do a duo of first stage boosters spied during their own Cape Canaveral arrivals. All that’s missing to round out a busy week of SpaceX transportation is the appearance of one or several payload fairings, although CEO Elon Musk says that the company will try to reuse Falcon Heavy Flight 2’s fairing on the first Starlink launch.

Said Starlink launch – unofficially labeled Starlink-1 – is currently scheduled for liftoff no earlier than mid-May, likely making it the SpaceX mission that will follow CRS-17. The most likely Falcon 9 S1 candidate is the thrice-flown Block 5 booster B1046, a move that would retire risk otherwise transmitted to customers. SpaceX has now flown two separate Falcon 9 boosters (B1046 and B1048) three times without major issue, meaning that the fourth flight of the same booster (and beyond) will be new territory for reuse at some level.

Beyond Starlink-1, SpaceX has the communications satellite Amos-17 and Radarsat Constellation Mission (RCM), both of which are understood to be targeting launch no earlier than (NET) early June. Finally, Falcon Heavy Flight 3 – carrying the US Air Force’s STP-2 mission – is scheduled to launch NET June 22nd, although some additional delays are probable.

From a business-as-usual perspective, the fact that Crew Dragon C201 failed during intentional testing on the ground means that it will likely be SpaceX’s least commercially disruptive failure yet. This could change for any number of reasons, depending on the conclusions drawn by the joint NASA-SpaceX investigation soon to begin, and it’s far too early to draw far-reaching conclusions. Chances are good that the impact to non-Crew Dragon launches will be minimal but only time will tell as SpaceX begins to quite literally pick up the pieces and start a deep-dive analysis of all data gathered from Saturday’s failure.

SpaceX and Elon Musk explain potential reasons for Starship loss

Published

on

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

Published

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

Published

on

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.
