TarsaaUpgrades at SpaceX’s most-used launch pad in Florida will gain a trial bustle Thursday with the liftoff of a Falcon 9 rocket with a Dragon cargo ship heading for the Global Place apart Reveal.
SpaceX’s Cargo Dragon spacecraft is verbalize for launch at 4:55 pm EDT (20:55 UTC) Thursday from Place apart Launch Complicated 40 (SLC-40) at Cape Canaveral Place apart Force Reveal in Florida. This mission, known as CRS-30, is SpaceX’s thirtieth resupply mission to the verbalize feature since 2012.
The computerized Dragon present ship will take off on high of a Falcon 9 rocket, then head for a month-long cease at the Global Place apart Reveal, where this would presumably well per chance deliver more than 6,000 pounds of hardware, recent food, and experiments for the lab’s seven-individual crew.
In the old few months, SpaceX has equipped the launch pad with the instruments essential to red meat up launches of human spaceflight missions on the Crew Dragon spacecraft. The Cargo Dragon tablet is the identical size and shape as SpaceX’s Crew Dragon, however it completely’s stuffed with cargo racks and storage platforms rather than seats and cockpit displays.
This week, SpaceX technicians possess used the newly attach in launch tower and crew gain admission to arm at SLC-40 to load time-sensitive experiments and affords into the Cargo Dragon tablet atop the Falcon 9 rocket.
“CRS-30 will be our first Dragon to launch from Pad 40 since we attach that recent crew tower in verbalize,” acknowledged Sarah Walker, SpaceX’s director of Dragon mission management.
Building recent functionality
Starting final Twelve months, building crews at Cape Canaveral erected segments of a more than 200-foot-tall steel lattice tower at SLC-40, lawful subsequent to the initiating blocks for SpaceX’s Falcon 9 rocket. Before then, SLC-40 became in step with a “super pad” architecture, with out any structures to service or gain admission to Falcon 9 rockets while they were vertical on the pad.
In November, contractors raised the crew gain admission to arm to an connect point near the high of the tower. This walkway will allow astronauts to plod into the Crew Dragon spacecraft all the map thru a launch countdown. It also affords gain admission to to the hatch on the Cargo Dragon spacecraft for final cargo loading.
Earlier this Twelve months, SpaceX tested an shatter out chute at SLC-40 that can presumably well per chance be used in an emergency to help astronauts and floor crews rapidly gain faraway from the pad. The chute is similar in feature to lope-wire baskets in use for decades at LC-39A, however as a substitute of using a basket from the high of the tower, personnel escaping a pad emergency would lope down a chute to elevate them a few hundred toes from the rocket.
SpaceX workers tested the pad shatter out chute final month at SLC-40. Gwynne Shotwell, SpaceX’s president and chief operator officer, took the ride down the chute. “Astronaut and personnel safety is SpaceX’s highest priority, which is why I had to in my understanding check the recent lope,” she posted on X, alongside a wink emoji.

“The group took commercially available off the shelf technology and applied it to the crew tower,” Kiko Dontchev, SpaceX’s vp of launch, wrote on X. “You also can very neatly be trained on it the identical methodology you are trained on using an emergency exit door on airplane. Easiest takes a pair of posthaste physical actions to deploy the lope and somebody can successfully stop it.”
As more of us shuttle to verbalize, namely on bigger autos worship SpaceX’s Starship, simplifying safety systems will be essential.
“This methodology will help us scale to bigger towers and spaceships (bear 100 of us on Starship),” Dontchev wrote.
SpaceX and its contractors performed all of this work as Falcon 9s fired off SLC-40 every few days with Starlink satellites and other missions.
For the final four years, all of SpaceX’s crew and cargo launches to the verbalize feature possess departed from Launch Complicated 39A (LC-39A) at NASA’s Kennedy Place apart Center, a few miles up the fly from SLC-40. In 2018 and 2019, SpaceX equipped LC-39A for Cargo Dragon and Crew Dragon missions before the company’s first human spaceflight mission in 2020.
Walker acknowledged the recent infrastructure added at SLC-40 is “almost functionally identical” to the instruments for crew missions at LC-39A. The main variations are the strategy of pad shatter out—the chute as a substitute of lope-wire baskets—and a more great elevator in the tower at SLC-40.
Beforehand, SpaceX used both SLC-40 and LC-39A for launches of its now-retired first-period Dragon cargo capsules, which had their final affords loaded before SpaceX raised the rocket vertical for launch. Cherish abnormal satellite tv for pc launches on Falcon 9s, both pads would possibly per chance presumably well per chance red meat up the first-period Dragon cargo missions.
“Due to this recent verbalize-of-the-art crew tower required for our human spaceflight missions, that late-load cargo operation obtained a wide toughen, too,” Walker acknowledged. “It is a lot more straightforward to load a large complement of time-severe NASA science into our Dragon spacecraft in the flight orientation.”
SpaceX has drastically ramped up its launch cadence since building LC-39A for Dragon missions. The company plans almost 150 Falcon 9 or Falcon Heavy launches this Twelve months. If you occur to’re flying rockets every two or three days, it’s inevitable two missions will pause up vying for the identical launch slots. Most honest now now not too long ago, that came about in February, when a NASA crew mission became willing to launch from LC-39A around the identical time as a narrow launch window for Intuitive Machines’ first commercial lunar lander. Each had to head off of LC-39A.
“Historically, Pad 40 has roughly change into our high rate pad,” Walker acknowledged. “We’ve gotten the time between launches all the map down to easily a pair of days.”
LC-39A has seen less use, primarily for Dragon crew and cargo flights, Falcon Heavy missions, and other “uniquely complex” missions worship the Intuitive Machines lander, Walker acknowledged.
