fires up Falcon 9 rocket for Crew-3 Halloween astronaut launch
The
Crew-3 mission is scheduled to lift off early Sunday morning (Oct. 31).

CAPE CANAVERAL, Fla. — SpaceX has fired up the rocket
that will launch its next crew of astronauts toward the International Space
Station this weekend.
The
private spaceflight company conducted a static-fire test before dawn Thursday
(Oct. 28) of its Falcon 9 rocket at
Pad 39A here at NASA's Kennedy Space Center. The test is one of the last major
milestones ahead of a planned launch on Sunday (Oct. 31).
That launch will kick off Crew-3, SpaceX's third operational crewed mission to the International Space Station for NASA. Crew-3 will send three NASA astronauts and one German spaceflyer to the orbiting lab.

Today's
static fire — a routine test that ensures a rocket is ready to fly —
occurred as expected in the predawn hours. Smoke and fire billowed briefly as
the Falcon 9's nine first-stage Merlin 1D engines were lit while the rocket
remained anchored to the pad.
Shortly
afterward, SpaceX tweeted that
the static fire was a success and that the company will be moving forward with
its planned Halloween launch.
Crew-3
is set to blast off at 2:21 a.m. EDT (0641 GMT) on Oct. 31, sending a Crew
Dragon capsule named Endurance skyward. Following a
successful liftoff, the Falcon 9's first stage is expected to land on one of
SpaceX's drone ships, called Just Read the Instructions. If all goes as
planned, Endurance will spend just under 24 hours trailing the space station
before arriving at the orbital outpost early Monday (Nov. 1).
Endurance is brand-new, but it sits atop a previously
flown rocket: This Falcon 9's first stage also launched a robotic cargo mission
to the space station in June.
The Falcon 9 and Endurance were rolled out of their
hangar and onto the launch pad at Complex 39A on Wednesday morning (Oct. 27).
Standing 215 feet (65 meters) tall, the pair was lifted upright later that
afternoon.
Secured to the launch pad, teams worked overnight to
prep the rocket for its static fire test. They loaded the rocket with
super-chilled propellants — kerosene and liquid oxygen.
The nine first-stage engines briefly fired at 1 a.m.
EDT (0500 GMT) Thursday, generating 1.7 million pounds of thrust while the
booster remained firmly on the ground. Engineers reviewed the data before
confirming that they would proceed with a launch on Sunday.

The
static fire test comes on the heels of a flight readiness review, which cleared the mission
for flight on Monday evening (Oct. 25), and the crew's
arrival in Florida. Raja Chari, Tom Marshburn, and Kayla Barron of NASA were
joined by the European Space Agency's Matthias Maurer as they arrived at
Kennedy Space Center on Tuesday afternoon (Oct. 26).
Up
next is a full dress rehearsal for the crew. Currently, forecasters at the 45th
Space Delta here at Cape Canaveral Space Force Station predict an 80% chance of
favorable conditions for liftoff on Sunday morning. The only cause for concern
is a slight chance of flight through precipitation.
