SpaceX and NASA are working together to make sure they’re ready to start flying crews to the space station. Two astronauts, Doug Hurley and Bob Behnken are preparing to launch on a Crew Dragon capsule, with a scheduled date of mid to late May for the historic launch.

As the world deals with the coronavirus, essential personnel at both NASA and SpaceX are continuing to progress to a crew flight. Since the final shuttle flight in 2011, NASA and other space agencies around the world have been forced to rely on Russian rockets as their sole means of transporting astronauts to and from space.

That will change with the next flight of SpaceX’s Crew Dragon capsule. The gumdrop-shaped spacecraft is set to carry Behnken and Hurley to the orbiting outpost. The length of their stay is still to be determined, but training efforts suggest that it will be longer than the original planned flight.

To that end, the duo has been working with NASA and SpaceX to practice day of launch procedures. On March 19 and 20, teams gathered in Firing Room 4 at NASA’s Kennedy Space Center to complete a series of full missions, from launch to landing. After the retirement of the shuttle fleet, NASA turned to the private sector to find its next generation of space taxi.

The space agency selected SpaceX and Boeing in 2014 to each build a spacecraft capable of ferrying crew to and from the space station. SpaceX’s Crew Dragon was the first to complete an uncrewed flight test, where the vehicle proved it could dock and undock itself from the space station. That test was a huge success and was followed on by a picture-perfect test of the Crew Dragon’s onboard escape system earlier this year.

Following the inflight abort test, all SpaceX needed to do was complete a few more tests of its Mark 3 parachute before NASA gave the all-clear to launch. But the company ran into a snag when it experienced two incidents back-to-back – the loss of a mock Dragon used for parachute testing and an unrelated in-flight rocket engine failure.

But SpaceX and NASA’s plans appear unphased, and the duo are working full steam ahead to the tentative May launch deadline. Key flight control teams stationed at their launch posts at NASA’s Kennedy Space Center, Johnson Space Center and SpaceX HQ have simulated the different phases of launch. In contrast, the astronauts have practiced launch procedures from their Crew Dragon simulator.

“The simulations were a great opportunity to practice procedures and to coordinate decision-making for the mission management team, especially with respect to weather,” Michael Hess, manager of operations integration for NASA’s commercial crew program said in a news statement.

“Simulation supervisors do a great job at picking cases that really make the team think and discuss,” he added.

During the most recent simulations, teams ran through an entire mission, from prelaunch countdown to ascent and docking with the station while previous tests ran through timelines from hatch closure to undocking from the space station as well as practiced free-flight in preparation for re-entry and splashdown.

The countdown is on as the Crew Dragon capsule undergoes its final testing and preparations at SpaceX facilities at Cape Canaveral Air Force Station in Florida. Once crew training and flight readiness reviews are complete, the spacecraft will be attached to its launcher: a shiny, new Falcon 9 booster.

If all goes according to plan, in late May, Bob Behnken and Doug Hurley will strap in and blast off the space station. There they will join fellow NASA astronaut, Chris Cassidy, who launches to the space station on April 9.

To ensure the mission gets off without a hitch, NASA and SpaceX are working closely and adhering to CDC guidelines to ensure teams stay safe and healthy. All non-essential employees are working from home, and the number of people coming in contact with the astronauts is minimal.

“The Space Station Program is looking forward to [having] another way to rotate crews to station to perform science and experiments to benefit all,” Hess said.

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.
