Destination Low Earth Orbit
Mission Description 33rd commercial resupply services mission to the International Space Station operated by SpaceX. The flight will be conducted under the second Commercial Resupply Services contract with NASA.

Cargo Dragon 2 brings supplies and payloads, including critical materials to directly support science and research investigations that occur onboard the orbiting laboratory.

As of 10:00 AM Saturday August 23, 2025. Launch times are subject to change or cancellation at any time. Consult SpaceX.com for more information.

Along with the usual gamut of food, gear, and crew supplies, CRS-33 will deliver a range of scientific experiments to the International Space Station. These include stem cells that promote bone formation, aimed at studying how to prevent bone loss in space. Dragon will also carry materials for 3D printing medical implants—research that could lead to better treatments for nerve damage back on Earth.

The Tortilla Express

Another item on the launch manifest for CRS-33 is roughly 1500 tortillas. They are a staple food aboard Station — convenient, quick, and quite handy to bundle up other food items…breakfast, lunch or dinner. They are a crumb-free condensed item, making the humble tortilla one of the most likely foods humans will carry to Mars and beyond.

Other payloads include bioprinted liver tissue for examining how blood vessels form in microgravity, and tools for printing metal cubes in orbit.

Planned Reboost Test For Cargo Dragon

Cargo Dragon will also conduct a reboost test to help maintain the station’s altitude. The boost system, housed in Dragon’s trunk, features its own propellant setup and uses a pair of Draco engines powered by existing hardware.

Starting in September 2025, the system will carry out a series of burns to demonstrate its ability to sustain the lab’s orbit. This follows Dragon’s first successful test of the reboost function on November 8, 2024, during NASA’s 31st commercial resupply mission with SpaceX.

Cargo Dragon is expected to stay docked at the station through December after which it will return to Earth off of the coast of California.

Booster: B1090

This will be the seventh flight of first stage B1090, which will be supporting this mission. Previously, B1090 launched O3b mPOWER-E, Crew-10, Bandwagon-3, O3b mPOWER-D, and two Starlink missions. Following stage separation, it will land on the A Shortfall of Gravitas, located downrange off the South Carolina coast. There will not be a sonic boom on the Space Coast after the launch.

Weather

The 45th Weather Squadron of Space Launch Delta 45 released their Launch Mission Execution Forecast yesterday afternoon, and it calls for a 70% chance of acceptable weather, with watch items being the usual summer items: cumulus clouds and nearby lightning.

Trajectory

Northeast, on the usual ISS route.

B1090 will touch down off the South Carolina coast aboard ‘A Shortfall of Gravitas.’

For official updates regarding launch times, SpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.

SpaceX, NASA and the Crew 11 astronauts beat the clouds and rain showers and launched before summer showers washed over Kennedy Space Center today, but just barely. With dark skies and rain rapidly advancing from the south, liftoff of SpaceX’s 18th crewed flight was at 11:43 AM ET from venerable Launch Complex 39A. Crew 11’s four astronauts are now on their way to the International Space Station after today’s launch, with an expected arrival time at the orbital outpost around 3 AM ET tomorrow, August 2.

Gravity Turn: After Max-Q and now in its supersonic flight phase, Falcon 9 enters another gear, leaving the contrail it just made behind quickly. The cloud is from the rocket, not the storms it was escaping on August 1, 2025.

Tempus fugit, a lot of clocks say: “time is fleeting.” For a facility as established and enduring as Cape Canaveral Space Force Station, it might seem like forever since the first rocket launched from here. Time has flown and so have thousands of rockets and missiles from America’s premier spaceport. Truth is, CCSFS has been open “only” 75 years, but it continues to have a bright future not only today but also for the long-term future.

SpaceX is set to launch Falcon 9 and the SES-operated O3b mPower satellites this evening from Space Launch Complex 40 at Cape Canaveral. Liftoff is set for 05:12 PM ET, with a two hour window extending to 07:12 PM ET.

Official weather forecasts have given the mission a 50/50 chance for acceptable weather, with roughly a 25% chance of thunderstorms in the launch area during the launch window. Keep in mind that acceptable conditions consider more than just rain, it also includes thunderstorm activity in the launch area as well as the lightning potential in the immediate vicinity of the rocket. To learn more about launch commit criteria, click here.

Boeing’s 9th and 10th O3b mPOWER satellites—launched in partnership with SES—will bolster the company’s push to deliver global connectivity from space. Leveraging Boeing’s fully software-defined payload technology, these satellites can dynamically allocate power to match user demand.

Today will mark the sixth mission for Falcon 9 first stage booster B1096, and after completing its share of the mission, the booster will touch down offshore on ASDS ‘Just Read The Instructions.’

Between Storms, SpaceX Launches GPS III-7 Aboard Falcon 9

It was a typical summer’s day here on the Space Coast: at first, sunny and warm, humid with an ever-present threat of a thunderstorm lingering off in the distance.

An hour and a half before today’s launch, while the countdown clock was ticking towards T-0, the skies made good on their threat of a thunderstorm, with plenty of lightning strikes and heavy showers near Space Launch Complex 40, where the GPS III-7 satellite, also known as SV-08, waited atop Falcon 9 for liftoff just before the end of the launch window at 1:38 PM Eastern Time.

United Launch Alliance’s Kuiper KA-01 mission was scrubbed last night due to persistent high winds and offshore showers. SpaceX has the range scheduled for a Starlink launch from KSC this evening, so ULA will be pushed back to at least Monday.

According to ULA CEO Tory Bruno on X.com, “Mighty Atlas’ count was very clean. Unfortunately, weather stayed rough. [We] appreciate support from the USSF Weather team.”

The Monday date is pending Eastern Range approval, among others, and may shift. As always, stay tuned.

Starlink 12-17

SpaceX is planning to launch another set of Starlink satellites to orbit from pad LC-39A at Kennedy Space Center this evening. The launch window opens at 9:54 PM ET and extends to 1:43 AM Friday morning. According to SpaceX, “If needed, additional launch opportunities are also available on Friday, April 11 starting at 9:15 p.m. ET.”

Destination Low Earth Orbit
Mission Description A batch of 21 satellites for the Starlink mega-constellation—SpaceX’s project for a space-based Internet communication system.

After concluding its duty powering the payload towards orbit, the first stage booster, B1083, will land on ASDS ‘A Shortfall of Gravitas’ which will be stationed on the Atlantic Ocean near The Bahamas. Since the booster is not returning directly to the Cape Canaveral region after liftoff, there will not be a sonic book over the Space Coast region.

Weather looks good, with only a 5% chance of a weather-related range violation. That said, it should be a beautiful evening to go to space.

This will be the 10th flight of B1083. Previously, it has launched Crew-8, Polaris Dawn, CRS-31, Astranis: From One to Many, IM-2, and four Starlink missions.

The trajectory is southeast, and Starlink 12-17 will pass just east of The Bahamas on its way to orbit.

ULA Atlas V Kuiper KA-01 Now Slated For Monday

Due to the SpaceX launch, this evening is not an option for United Launch Alliance to fly Atlas V and the Kuiper KA-01 mission. At this point in time, secondary sources (FAA, etc) are pointing to an attempt this coming Monday, April 14th.
