KENNEDY SPACE CENTER, FL – Day
long threats of poor weather from anvil clouds, thunderstorms and lightning put
an end to hopes to launch of a SpaceX Falcon 9 on a cargo delivery run for NASA
to the International Space Station as the countdown clock clicked relentlessly down
to T-Zero - until a scrub was finally called as expected in the final moments
before the hoped for liftoff this evening July 24.
The SpaceX launch team decided to give it a try despite the continuing poor weather forecast all day.
The scrub was called out with a ‘Hold, Hold, Hold’ from the launch team at T Minus 30 seconds Wednesday evening, July 24 before the planned liftoff of the SpaceX Falcon 9 at 6:24 PM ET (2224 GMT) with the Dragon CRS-18 cargo ship from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida – bound for the ISS.
“The launch of SpaceX’s 18th Commercial Resupply Services mission to the International Space Station – scheduled for this evening – has scrubbed due to unfavorable weather conditions,” said NASA.
The SpaceX Falcon 9 launch is now scheduled for Thursday, July 25, at 6:01 p.m. EDT
Launch coverage will begin at 5:45 p.m. on NASA TV and the agency’s website.
"A launch on Thursday would result in the Dragon spacecraft arriving to the space station Saturday, July 27," said NASA.

Unfortunately the weather outlook remains poor for Thursday with only a 30% chance of acceptable conditions.
Meteorologists with the U.S. Air Force 45th Space Wing predict only a 40% chance of favorable weather for the SpaceX Dragon launch on July 25.
The primary weather concerns are cumulus clouds and their associated anvil clouds, as well as lightning.
After Thursday the next liftoff opportunity is around Aug. 1, SpaceX said at the prelaunch briefing for media at the KSC Press Site.

Among the cargo will be a very important docking
adapter known as International Docking Adapter-3 (IDA-3),
which is required to be on station in order for the new commercial
crew spaceships from SpaceX and Boeing to dock at the orbiting outpost.

Also aboard is the Techshot 3D BioFabricationl Facility (BFF) - the first ever 3D printer
capable of manufacturing human tissue in orbit.
1st experiments will focus
on printing human cardiac cells. This 500 lb unit was on display at the
KSC press site – see our photo.

The CRS-18
mission features a once flown Falcon 9 Block 5 version rocket that launched in
May 2019 on the CRS-17 resupply mission -also from pad 40.
The Dragon is also recycled and marks the first time that
SpaceX will use a Dragon for the third time.
This Dragon CRS-18 Dragon cargo ship previously launched in
April 2015 on CRS-6 and December 2017 on CRS-13.
The two stage Falcon 9/Dragon rocket stands
about 213-feet (65-meters) tall.
The weather outlook is not good. Meteorologists
with the U.S. Air Force 45th Space Wing predict only a 30% chance of favorable
weather for the SpaceX Dragon launch on
July 25.
The primary weather concerns are cumulus
clouds and their associated anvil clouds, as well as lightning.
The 20-foot
high, 12-foot-diameter Dragon CRS-16 vessel is jam packed with more than 5000 pounds (2300 kilograms) of science
experiments, research hardware, space parts, food water, clothing and more supplies
for the six person Expedition 60 crew.
The research gear will support dozens of the
more than 250 science and
research investigations that will occur during Expeditions 60 and
beyond.

Furthermore
Dragon’s unpressurized trunk is carrying the Boeing-built International
Docking Adapter-3 (IDA-3)
to orbit.
IDA-3 fills up most of the truck and has a mass
of 1177 pounds (534 kg).
Astronauts will use the stations Canadian-built robotic
arm to pluck IDA-3 from the trunk and install it onto the space-facing
zenith port of the station’s Harmony module.
IDA-3 will become the second docking adapter for
the astronaut carrying commercial crew vehicles –joining IDA-2 - thereby allowing
both the Boeing Starliner and SpaceX Crew Dragon to simultaneously dock at the
ISS and offering vast advantages and expanding opportunities to NASA to overlap
commercial crew missions - much like is currently possible for Russian Soyuz
capsules.
IDA-3 replaces
IDA-1 which was lost when a prior SpaceX Dragon was lost during a Falcon-9 launch
failure in 2015 of the CRS-7 mission.
IDA-2 arrived
in 2016 and was used successfully for the first time for the docking of the
SpaceX Demo-1 Commercial Crew
Program test flight in March 2019.
“Dragon will dock to the space station Friday,
July 26, and be greeted by NASA astronauts Nick Hague,
Christina Koch
and Andrew Morgan.
Using the station’s robotic arm, Hague will grab, or grapple, Dragon with Koch
providing backup. Morgan will assist by monitoring telemetry during Dragon’s
approach. After Dragon capture, mission control in Houston will send ground
commands for the station’s robotic arm to rotate and install it on the bottom
of the station’s Harmony module,” according to NASA.
SpaceX was awarded an approximately $3.1 Billion contract from NASA to launch 20 Dragon cargo missions to the orbiting outpost through 2019 under the Commercial Resupply Services-1 (CRS-1) agreement that was amended in 2015 and increased from an original value of $1.6 Billion.

Three missions
remain: CRS-18, CRS-19 and CRS-20.
NASA also awarded a CRS
contract to Northrop Grumman that has likewise been increased.
Both companies also won new cargo mission contracts under
the Commercial Resupply Services-2
(CRS-2) agreement awarded last year.
