From NASA's Kennedy Space Center in Florida, you're watching live coverage of the 15th
SpaceX cargo resupply mission to the International Space Station.
Hi, I'm Stephanie Martin, and thanks for joining us.
Today's launch to the station is scheduled for 5:42 eastern this morning from Space Launch
Complex 40 on Cape Canaveral Air Force Station.
Today we have team coverage from Dan Huot at Station Mission Control in Houston, Tori
Mclendon and Mike Curie at NASA's Control Center, SpaceX's Mike Hammersley, directly
from their Mission Control in Hawthorne, California, and Amanda Griffin is standing by with several
experts who have hardware and experiments aboard the Dragon.
Today's launch will be SpaceX's 15th cargo resupply mission to the International Space
Station.
And the second SpaceX resupply mission of the year.
The Dragon spacecraft and Falcon 9 rocket will deliver about 5,900 pounds of research,
crew supplies and hardware to the orbiting laboratory.
Today's launch window is instantaneous, meaning SpaceX has only a single second to launch
off Space Launch Complex 40 at Cape Canaveral Air Force Station, adjacent to NASA's Kennedy
Space Center.
We are now 26 minutes away from launch.
Let's check in with NASA's Tori Mclendon and Mike Curie.
Thanks Stephanie.
I'm Tori Mclendon, and with me is Mike Curie.
Good morning Tori.
We are looking forward to today's launch, we're one day removed from an official full
Moon.
And the time of launch is 44 minutes away from sunrise here on Florida's spacecoast.
So, I'm looking forward to a really, probably spectacular view of the Falcon 9 and Dragon
as they lift off on the launch pad this morning.
Sounds great.
We're definitely looking forward it.
We are actually here live at Hangar AE on Cape Canaveral Air Force Station, which is
not far from the launch site of today's Falcon 9 rocket that will lift off from Space Launch
Complex 40.
That's right.
And you're looking at a live shot of the launch site with the Falcon 9 rocket with gaseous
oxygen venting as the rocket is being prepared for launch at 5:42 and 42 seconds a.m.
Eastern time.
As Stephanie was mentioning, it's an instantaneous launch window.
So, 42 seconds after 5:42 a.m. will be the time of launch this morning.
At that time, the International Space Station will be over the South Pacific, southeast
of New Zealand, at an altitude of 258 statute miles.
That's right.
And the launch today would have the Dragon spacecraft that is filled with 5,900 pounds
of research, crew supplies and vehicle hardware being captured by the International Space
Station on Monday, July 2, at 7 a.m.
Eastern.
The Dragon would then connect to the station's Harmony module.
Launch teams received a weather briefing from U.S. Air Force 45th Space Weather Squadron
officer Mike McAleenan.
He's our launch weather officer.
He says that we can expect good weather today.
Probability of violation is only 10 percent.
That means we're 90 percent favorable.
Light winds, 8 to 10 miles per hour from the southwest.
Temperature at the time of liftoff expected to be 76 degrees.
The only concerns, the cumulus and anvil cloud rules.
But again, at this time, Mike McAleenan is saying that we have thin and high cirrus clouds.
There's really not much of a probability of anything happening between now and the time
of launch.
So, it looks like weather's not going to be a concern for us today.
Sounds great.
Teams are also working through the necessary procedures to prepare the Falcon 9 rocket
and the Dragon spacecraft for launch.
And that includes loading fuel into both stages of the rocket and making sure that all systems
are properly checking out.
So far, the countdown has progressed toward the timeline.
Loading of RP-1 fuel began at T-minus one hour, 10 minutes, at 4:32 a.m.
Loading of liquid oxygen began at T-minus 35 minutes at 5:07 a.m.
So at T-minus 23 minutes, 25 seconds and counting, that is the current status from Falcon Launch
Control, Stephanie.
And for now we'll send it back to you.
