Ready to Rumble: Flight Tests Launching in 2019

NASA’s Commercial Crew Program and private industry partners, Boeing and SpaceX, will make history in 2019 with the return of human spaceflight launches to the International Space Station from U.S. soil. Get ready for the rocket rumble: 2019 Preview


SpaceX Demo-1 Spacecraft and Rocket at Launch Pad

SpaceX’s Crew Dragon spacecraft and Falcon 9 rocket are positioned at the company’s hangar at Launch Complex 39A at NASA’s Kennedy Space Center in Florida, ahead of the Demo-1 flight test targeted for January 17, 2019.

On Dec. 18, Vice President Mike Pence had the opportunity to tour the hangar and see the launch hardware up close.

The Demo-1 flight test is the precursor to the company’s Demo-2 flight test, which will fly NASA astronauts to the International Space Station as part of NASA’s Commercial Crew Program. Demo-2 is targeted for June 2019.

Commercial Crew: 2018 Year in Review

NASA and our partners have been busy this year manufacturing flight hardware, testing their systems and preparing for flight tests.  Our nine U.S. crew members have also participated in spacecraft system testing checkouts, spacesuit fit checks and launch simulations.

Here’s a look at some of our many accomplishments in 2018. 

Final Rocket Segment Arrives in Florida

The first stage of the rocket that will launch Boeing’s CST-100 Starliner spacecraft to the International Space Station on the company’s uncrewed Orbital Flight Test has arrived in Cape Canaveral, Florida, completing delivery of all hardware for the United Launch Alliance (ULA) Atlas V rocket.

The Atlas V first stage booster rolled off of the Mariner cargo vessel on Dec. 7 at the Cape Canaveral wharf for the short drive to the Atlas Spaceflight Operations Center for receiving inspections and checkout.

Mariner is the ship that ULA uses to transport rocket segments, or stages, from the company’s manufacturing plant in Decatur, Alabama to the launch site in Florida. The Atlas V stage departed the factory Nov. 28 for the journey of nearly 2,000 miles.

Early in 2019, the stage will move further north to the Vertical Integration Facility to be raised on the mobile launch platform. The twin solid rocket boosters will be mounted to the bottom of the first stage. Then, the top of the rocket stack, which consists of the interstage, Centaur upper stage and payload adapter, will be hoisted into position.

This delivery means all of the hardware that ULA needs to launch the first Boeing Starliner has been received at the launch site for final integration.

NASA’s Commercial Crew Program is working with Boeing and SpaceX to return human spaceflight launch capability to the United States. Following Boeing’s Orbital Flight Test in March 2019, the Starliner will launch on the Atlas V rocket with astronauts aboard for a Crew Flight Test to the space station targeting August 2019. Boeing also will fly a pad abort test in between the uncrewed and crew test missions.


New Target Date for SpaceX Demo-1

NASA and SpaceX provided an update on Jan. 10, 2019. For the details on the flight tests and the latest schedule, visit

NASA and SpaceX have agreed to move the target launch date of the uncrewed Demo-1 flight test to the International Space Station. SpaceX coordinated with the Eastern Range for a launch on Thursday, Jan 17. This adjustment allows the return of the Dragon spacecraft from the company’s 16th commercial resupply services mission. SpaceX’s Demo-1 will provide key data associated with the ground, integrated rocket and spacecraft, and autonomous docking systems, and the landing profile ahead of the company’s flight test with astronauts, known as Demo-2.

“We still have more work to do as the certification process, hardware development and readiness reviews continue,” said Kathy Lueders, manager of NASA’s Commercial Crew Program. “The key readiness reviews along with NASA’s continued analysis of hardware and software testing and certification data must be closed out prior to launch. The upcoming steps before the test missions are critical, and their importance can’t be understated. We are not driven by dates, but by data. Ultimately, we’ll fly SpaceX Demo-1 at the right time, so we get the right data back to support the in-flight abort test and the next test flight when our astronauts are aboard. However, the fact we’re coordinating target dates with the Eastern Range is a great example of the real progress we’re making with commercial crew and how close we are to actually flying American spacecraft and rockets from American soil again.”

First Starliner to Launch Crew Ready for Environmental Testing

Boeing technicians carefully close Starliner’s shipping container at the company’s Florida factory ahead of its trip to El Segundo, Calif.

The Boeing CST-100 Starliner spacecraft destined to fly astronauts to the International Space Station for Boeing’s Crew Flight Test (CFT) as part of NASA’s Commercial Crew Program is ready to undergo a series of flight-like simulations similar to the actual environments the spacecraft will experience during different stages of flight.

Boeing’s first crewed Starliner finished initial production at Kennedy Space Center, Fla. and is readied for its cross-country trip.

The spacecraft recently arrived at the company’s facilities in El Segundo, California for the series of tests. In order to ship the spacecraft, technicians painstakingly prepared and secured Starliner inside its shipping container on Nov. 12, before the spacecraft completed its 10-day, cross-country trip.

Now, Starliner will begin the test campaign wherein acoustic and vibration testing will simulate the environment during launch and ascent, thermal vacuum testing will expose Starliner to the extreme heat and cold it will experience in orbit, and electromagnetic interference/electromagnetic compatibility testing will make sure that those signals or radiation do not interfere with operations on Starliner or with sensitive equipment on station. The series of tests are expected to last about three months.

Starliner is unboxed inside Boeing’s satellite test facilities in California to prepare for environmental qualification testing.

The company’s CFT is targeted for August 2019, and will be Starliner’s first flight with crew onboard. Following the CFT, Boeing will refurbish the spacecraft for regular crewed missions to the space station.

During these environmental tests, Boeing also expects to complete production in its Florida factory on the Starliner to be flown in the company’s uncrewed Orbital Flight Test, targeted for March 2019.

The shipping container with Starliner’s crew module arrives at Boeing’s facilities in El Segundo, Calif.

Boeing is developing the Starliner spacecraft as part of NASA’s Commercial Crew Program. The spacecraft will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

NASA’s Commercial Crew Program Target Test Flight Dates

The next generation of American spacecraft and rockets that will launch astronauts to the International Space Station are nearing the final stages of development and evaluation. NASA’s Commercial Crew Program will return human spaceflight launches to U.S. soil, providing safe, reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements.

To meet NASA’s requirements, the commercial providers must demonstrate that their systems are ready to begin regular flights to the space station. Two of those demonstrations are uncrewed flight tests, known as Orbital Flight Test for Boeing, and Demo-1 for SpaceX. After the uncrewed flight tests, both companies will carry out spacecraft abort tests to demonstrate their crew escape capability during an actual on-pad, or ascent emergency. The final test flights for each company will be crew flight tests to the space station prior to being certified by NASA for crew rotation missions. The following target dates reflect the current schedule as of Thursday, Jan. 10.

Test Flight Planning Dates:
Boeing Orbital Flight Test (uncrewed): March 2019
Boeing Pad Abort Test: Between OFT and CFT
Boeing Crew Flight Test (crewed): August 2019
SpaceX Demo-1 (uncrewed): No earlier than February 2019
SpaceX In-Flight Abort Test: Between Demo-1 and Demo-2
SpaceX Demo-2 (crewed): June 2019

SpaceX also completed a pad abort test in 2015. Following the test flights, NASA will review the performance data and resolve issues as necessary to certify the systems for operational missions.  Boeing, SpaceX and the Commercial Crew Program are actively working to be ready for the operational missions; however, as with all human spaceflight development, learning from each test and adjusting as necessary to reduce risk to the crew may override planning dates.

Anticipated Readiness Dates for Operational Missions:
First operational mission: August 2019
Second operational mission: December 2019

Launch Teams Simulate Boeing Uncrewed Flight Test Prelaunch Procedures

Inside the Boeing Mission Control Center at Kennedy Space Center, Fla., launch control teams for the CST-100 Starliner rehearse a fully integrated prelaunch simulation of the spacecraft’s upcoming Orbital Flight Test. Boeing Spacecraft Launch Conductor Louis Atchison speaks on console to the Mission Management Team as the countdown in the launch simulation progresses.

Boeing, United Launch Alliance (ULA) and NASA completed an integrated rehearsal of prelaunch procedures for Boeing’s first uncrewed test flight of the CST-100 Starliner spacecraft aboard an Atlas V rocket for commercial crew missions to the International Space Station. The simulation, conducted on Nov. 7, focused on launch procedures beginning at five hours before launch, and continuing through a simulated scrub before liftoff.

Inside the White Flight Control Room in the Mission Control Center at NASA’s Johnson Space Center in Houston, Boeing’s Flight Control Team rehearses prelaunch procedures for the company’s Orbital Flight Test of Starliner.

The rehearsal consisted of launch teams participating from Boeing and NASA facilities at Kennedy Space Center in Florida and Johnson Space Center in Houston. It incorporated voice communications, pad closeout events, polling for tanking, or fueling, readiness, and discussions about conditions, including flight hardware and weather.

Boeing’s Pad Team Lead, Melanie Weber, performs simulated prelaunch operations inside the Boeing Mockup Trainer for the Starliner located in Houston. As launch control teams from NASA, Boeing and ULA participate in a prelaunch rehearsal for the Starliner’s upcoming Orbital Flight Test, Weber practices her launch day pad operations from inside the trainer.

Prelaunch anomalies were introduced into the rehearsal to provide opportunities for the teams to execute their resolution process. A scrub was called during the countdown rehearsal, allowing participants to test procedures for a delay and a decision to de-tank and prepare for a launch attempt the next day.

Boeing’s first uncrewed test flight, known as Orbital Flight Test (OFT), is slated for launch aboard an Atlas V rocket in March 2019. This will be the first flight of the Starliner, and it is a major step toward demonstrating that the spacecraft is ready to begin carrying astronauts to the space station.

Members of NASA’s launch support team gather in the Emergency Operations Center (EOC) at Kennedy Space Center, Fla. to rehearse prelaunch operations for the Orbital Flight Test of Boeing’s Starliner spacecraft. The EOC is where directors for medical triage and launch rescue will execute real-time responses in the unlikely event of an emergency on launch day.

Boeing is manufacturing three Starliner spacecraft in collaboration with NASA’s Commercial Crew Program. Starliner is designed to be reused up to 10 times.
