NASA and SpaceX are less than two weeks away from the first crewed mission to launch from U.S. soil in nearly a decade. But there’s still work to do before the craft blasts off towards the International Space Station.

On Friday, May 15, the Crew Dragon spacecraft journeyed from a fueling facility at Cape Canaveral’s Air Force Station to launch pad 39A at NASA’s Kennedy Space Center. Tucked inside the SpaceX hangar, the craft will undergo testing and checkouts before being attached to it Falcon 9 launcher in a few days.

The Dragon was filled up with hypergolic fuel (hydrazine and nitrogen tetroxide), which its built-in escape system and onboard thrusters use to maneuver.

Liftoff is scheduled for May 27 at 4:33 p.m. EDT (2033 UTC). At that time, NASA astronauts Bob Behnken and Doug Hurley will rocket towards space, and synch up with the space station less than 24 hours later. During their time on orbit, the duo will put the Crew Dragon’s systems to the test.

Hurley will get to manually pilot the autonomous spacecraft, ensuring the control systems are working as expected. Then the spacecraft will begin the docking process. But before Dragon can attach itself to the space station, it has to be prepped for launch.

This week, SpaceX crews will inspect the Dragon’s electrical and mechanical attachments before attaching it to the Falcon 9. Using a massive crane, the crew will hoist the Dragon onto the rocket. The duo will then be loaded onto SpaceX’s transporter and make the trek up to the launch pad.

Hurley and Behnken know this pad well. Both astronauts flew their previous missions after launching from this pad. The crew is set to make the trip to Kennedy this week, arriving on May 20. They’ve been in official mission quarantine since May 13, although the duo has quarantined with each other for several weeks now, with minimal contact with other non-essential staff members.

Once the Dragon and Falcon are on the launch pad, SpaceX engineers will take some time to inspect and examine the vehicles before putting the Falcon through some routine pre-launch testing, including a fueling run and a static fire test.

The next major hurdle before launch will be a flight readiness review, which will take place on May 21. If that goes as planned, there will be a final launch readiness review on May 25th. In the meantime, after they arrive at the launch site, Behnken and Hurley will undergo some last-minutes training, make sure their spacesuits are fitting correctly, and do a full launch practice run on Saturday, May 23.

According to NASA, there is still a lot of work to be done ahead of the May 27th launch date, but currently, everything is on schedule. Once on station, Behnken and Hurley will stay up to four months on the orbital outpost before returning to Earth.

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.
