CAPE CANAVERAL, FL – In a historic first SpaceX engineers ignited the first stage engines of the first integrated Falcon 9 rocket and space worthy Crew Dragon capsule this afternoon, Thursday, Jan. 24 and conducted the first ever static fire test of the combined booster stack that will launch from NASA’s historic Launch Complex 39A at the Kennedy Space Center in Florida and eventually lead to the long awaited and long delayed return of human spaceflight capabilities to the United States later this year.
This particular engine test carried out today at 4 p.m. EST (2100 GMT) involved the actual rocket hardware that will fly on the first pathfinding demonstration flight dubbed Demo-1; which is an uncrewed test flight that is now targeted to launch the Crew Dragon capsule to the International Space Station (ISS) several weeks from now - at some point in mid to late February, SpaceX confirmed via tweet late this evening.
A source told Space UpClose that the test duration was a bit shorter than planned. Despite that the results were apparently good enough for SpaceX – although it took several hours longer than normal for SpaceX to announce the successful outcome.
“Static fire test complete—targeting February launch from historic Launch Complex 39A for Crew Dragon’s first demonstration flight!" SpaceX tweeted along with some video views of the test.

Space UpClose observed the static fire test as illustrated
in my photos taken this afternoon at a distance from Titusville, FL.
Reports indicate a launch target of NET (no earlier than) Feb 23.
Unfortunately at the moment there is no end in sight to the US government shutdown.
Thus a true target Demo-1 launch date likely remains elusive since most NASA workers remain furloughed. A small team of NASA workers assigned to the Demo-1 mission to oversee and verify the work carried out by SpaceX technicians at pad 39A remains on duty - exempted from the furlough but without being payed. Their work is deemed essential for ISS operations
SpaceX technicians rolled out the integrated Falcon 9 rocket and Crew Dragon overnight Tuesday morning, Jan 22, and raised it vertical in the 8 a.m. EST hour in anticipation of the crucial static fire test initially planned for Jan. 23 but postponed to today Jan 24.
The Crew Dragon is a significantly enhanced version of the SpaceX
Cargo Dragon including life support systems for astronauts and upgraded composite overwrapped pressure vessels (COPV) filled with helium in the Block 5 version of the Falcon 9 rocket to minimize the potential for a
friction ignition of carbon fibers as occurred during the AMOS-6 catastrophe.
If all goes well with Demo-1, then the crewed Demo-2 mission would launch to the ISS with a pair of NASA astronauts – Bob Behnken and Dour Hurley - sometime in the last half of 2019.

The hold down
static fire test is routinely carried by SpaceX to ensure all is ready with the
rocket.
The crew access arm, or astronaut walkway, was retracted away from the Dragon capsule about half an hour prior to ignition. Occasional venting of liquid oxygen was observed during the fueling process.
During the engine test all nine Merlin 1D first stage engines were very briefly ignited for several seconds. The resulting exhaust plume generated was directed away from the north side of the flame was dissipated rapidly.
During the hold down static fire test, the rocket’s first and second stages are fueled with liquid oxygen and RP-1 propellants just like an actual launch, and a simulated countdown is carried out to the point of a brief engine ignition.
Today’s hold down engine test with the erected Falcon 9 rocket involved the ignition of all nine Merlin 1D first stage engines generating some 1.7 million pounds of thrust at pad 39A while the two stage rocket was restrained on the pad.
The flight utilizes the new Falcon 9 booster core #B1051 and the Crew Dragon – both on their maiden missions.
The integrated stack rolled out once before in early January for pad fit checks and checkout operations.
The stack will now be lowered and rolled back into the processing hangar at pad 39A for final checks and analysis and loading any gear which may fly.
The ship will dock at the ISS a day or so after liftoff and remain a few weeks into March.
The SpaceX Crew Dragon and Boeing Starliner under currently development to once again ferry American astronauts to the International Space Station (ISS) from American soil on American rockets to end our sole reliance on the Russian Soyuz since the forced shutdown of NASA's space shuttles in 2011.

The private SpaceX
crew dragon will fly on the Demo-1 mission to the ISS and was developed under
the auspices of NASA’s Commercial Crew Program.
Although no
astronauts will be aboard this test flight, two crew members will soar to orbit
on the follow-up Demo-2 test flight several months later in mid 2019 or later -
according to current projections.
In another sign showing progress towards astronaut launches, a mock-up of SpaceX’s privately built Crew Dragon spaceship sailed into Port Canaveral last week on the dedicated ‘GO Searcher’ recovery ship after conducting trails at sea as practice demonstrations to prepare the naval team for hoisting real capsules holding NASA astronaut crews on deck after their fiery return from space and splashdown in the Atlantic Ocean.

“Incredible opportunity to see @SpaceX's Dragon 2 Capsule - an important part of the future of American human space exploration as we aim to return American astronauts to space on U.S. rockets from U.S. soil!” VP Pence tweeted on Dec. 18, 2018 from Launch Complex 39A at KSC.
The goal of NASA’s Commercial Crew Program is to restore America’s capability to launch human spaceflight missions from the U.S. to low Earth orbit (LEO) and the International Space Station (ISS) on American capsules with American rockets from American soil - and thereby end our 100% reliance on the Russian Soyuz capsules.
The US became solely dependent on Russia due to the forced shutdown of NASA’s Space Shuttles back in 2011 when both political parties failed to provide sufficient US Federal budget funding support to NASA’s human spaceflight programs.
Target timelines for return US human spaceflight capability have been pushed back repeatedly since 2015 due to endless mindless political squabbling as well as technical challenges.
SpaceX will have to accomplish all this critical work and
do it safely for NASA with significantly fewer staff after the company
announced a 10% reduction in workforce earlier this month – as I reported here.
Here’s a link to my Fox News 35 Orlando
interview and commentary about the negative impact of the US Government
shutdown on NASA- as seen on Jan 8:
