Summer is nearly back on the Space Coast, with warm temperatures and a persistent threat of rain in the afternoon and evenings — typical weather here, and it will stay this way for several months. That being said, Atlas V was able to beat the weather last night and launched at the opening of its window, with liftoff at 7:01 PM ET after an apparently quiet countdown, save for some concerns about the energy potential of a nearby anvil cloud (Cumulonimbus incus) lingering near the launch pad before dissipating.

The launch carried 27 Amazon Kuiper satellites to orbit. These were the first operational units of Amazon’s planned Internet service constellation, which is planned to feature some 3,236 units when fully built out.

Atlas V was outfitted in its 551 configuration, meaning it had five GEM 63 solid rockets strapped onto the booster for additional lift. It also had a five-meter fairing, the largest used on the venerable member of ULA’s stable. Tory Bruno, CEO of ULA, calls this setup “The Bruiser” and that’s an apt name: it’s a big rocket and has a lot of power. Good thing, because yesterday, Atlas V carried the most weight to orbit in 155 missions so far.

The launch was nominal, as was the flight to orbit. At 7:18 Tory Bruno announced on X.com that the payload was in orbit, and later, after deployment, Project Kuiper posted that it had established communications with all 27 Kuiper satellites. With that, the mission was a full success.

United Launch Alliance is set to launch and Atlas V 551 this evening from Space Launch Complex 41 at Cape Canaveral Space Force Station. The launch window opens at 7:00 PM ET and closes again at 9:00 PM the same day.
This will be ULA’s first launch this year. The company is winding down Atlas V launches, with only fifteen remaining, tonight’s launch included. ULA also recently retired Delta IV Heavy, and launched the last one a year ago today. The company is moving towards its Vulcan rocket, which it has launched twice. Vulcan recently received USSL certification for its new Vulcan rocket, which is now awaiting payloads prior to its next flight.
As is customary with Atlas V, all stages are expendable, so there will be no landing and retrieval of the booster. After its job is done for the day, it will crash into the ocean and sleep with the fishes.

Weather
The 45th Weather Squadron of Space Delta 45 has posted their Launch Mission Execution Forecast, and they are rating the chances of a weather violation at 25% on Monday, April 28, with chances dropping drastically to only a 10% chance of weather being an issue on Tuesday, April, 29th.
Trajectory
Northeast. Depending on when Atlas V launches, it may put on quite a show. Local sunset is 7:45 PM ET, so if the launch is at the opening of the window, we will see a beautiful sunset launch. If it is delayed an hour, the sun will have set on the ground, but Civil Twilight last until 8:09 PM and that means that Atlas V’s plumes will still be in sunlight up high. It might be interesting, but forecasting a jellyfish plume is tricky.
What Is Project Kuiper?
Similar to SpaceX’s Starlink, Project Kuiper is Amazon’s initiative to provide global broadband access through a constellation of over 3,000 satellites in low Earth orbit (LEO).
Announced in 2019, the project’s goal is to deliver fast, affordable internet connectivity to unserved and underserved communities worldwide. Like Starlink, by leveraging LEO satellites, Project Kuiper aims to provide low-latency broadband services to a diverse range of customers, including individual households, schools, hospitals, businesses, and government agencies.
Atlas V, with Kuiper K-01, stands at the ready on the launch mount at SLC-41.

To achieve this, Amazon plans to deploy some 3,236 satellites at altitudes ranging from 590 to 630 kilometers. The company has secured agreements for up to 83 launches over a five-year period, utilizing various launch providers such as Arianespace’s Ariane 6, Blue Origin’s New Glenn, and United Launch Alliance’s Atlas V and later, Vulcan Centaur.

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.

Launch Viewing: In Person
The southern viewing spots are the best for this launch, but none are particularly close except for Playalinda Beach. Problem is, Playalinda closes at 8PM, so unless the launch is right on time, it won’t be an option.
The best free options are available for spectators: 528 West at the Banana River Bridge, Jetty Park and Cherie Down Park in Cape Canaveral. Southern Titusville parks on Washington Avenu / US-1 are also good: Kennedy Point and Rotary Riverfront Park are your best bets.

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.”

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.

Falcon Family Returns To Flight, For This One Flight
The flight will mark the return to flight for Falcon family rockets after the September 28, 2024 launch of Crew 9 from Cape Canaveral, but according to the FAA it is for the Hera After launching NASA’s Crew 9 mission with Cosmonaut Aleksandr Gorbunov and NASA Astronaut Nick Hague aboard Crew Dragon on their mission to the International Space Station, the second stage of Falcon 9 separated from the capsule and was later commanded to fire its engine one last time in order for it to re-enter Earth’s atmosphere.
A specific area in the Pacific Ocean was targeted so as to minimize any risk of surviving debris causing injuries or property damage. The second stage’s final burn was “off-nominal,” according to SpaceX, and the stage re-entered outside of its designated area. SpaceX immediately announced it was “pausing” Falcon 9 flights while it investigated the matter and two days later, the FAA announced that it was requiring a formal investigation into the incident.

That investigation put the Monday, October 7 target date for Hera’s launch in doubt, but SpaceX has been given a special exemption for the Hera flight because the second stage will not be re-entering Earth orbit:
Assuming a successful LRR (Launch Readiness Review), Falcon 9 will again soar over Florida skies tomorrow morning.
Payload
According to ESA, “Hera is a planetary defence mission under development at the European Space Agency. Its objectives are to investigate the Didymos binary asteroid, including the very first assessment of its internal properties, and to measure in great detail the outcome of NASA’s DART mission kinetic impactor test. Hera will provide extremely valuable information for future asteroid deflection missions and science; increasing our understanding of asteroid geophysics as well as solar system formation and evolutionary processes.”
SpaceXwill have a live stream of the launch on its website. This will also be available on the X platform. Coverage starts about fifteen minutes before liftoff.

Launch Viewing: In Person
Since the launch is during the morning, a lot of options are available for spectators: Jetty Park, the Banana River Bridge on FL 528 W or the southern Titusville parks on Washington Avenue / US-1 are your best bets.
Cocoa Beach will have great views of the launch once it clears any obstructions from the rising rocket and a viewer’s location.
Playalinda Beach is several miles north of the launch pad, but ignition and of course the flight of the rocket are visible from that location. If you go, go early in case the crowds are heavy.
This flight is one where the booster will be expended after its duty cycle. This is being done in order to get the maximum performance possible out of the launch vehicle. That in mind, there will be no sonic boom in the Space Coast region for a returning booster.

United Launch Alliance successfully launched its second Vulcan rocket this morning from Space Launch Complex 41 at Cape Canaveral. The launch was not a perfect one, however, as Vulcan survived a very close call when one of the two solid-rocket boosters on the first stage partially failed and lost its nozzle in flight.
Despite a partial loss of thrust from the errant SRB, ULA’s flight software and engineering teams were able to make corrections to trajectory of the rocket as it continued to ascent.

United Launch Alliance successfully launched its second Vulcan rocket this morning from Space Launch Complex 41 at Cape Canaveral. The launch was not a perfect one, however, as Vulcan survived a very close call when one of the two solid-rocket boosters on the first stage partially failed and lost its nozzle in flight.
Despite a partial loss of thrust from the errant SRB, ULA’s flight software and engineering teams were able to make corrections to trajectory of the rocket as it continued to ascent.
Later, ULA CEO Tory Bruno would say that the SRB had “an observation” and he added quickly that the mission was a success.

Vulcan uses Northrop Grumman-built GEM 63XL solid rocket boosters to provide additional thrust for the vehicle and to increase its capabilities. GEM motors have a long history of usage, and the 63XL edition was flying its third and fourth flights. Two other GEM 63XLs flew with no problem on Vulcan Cert-1.

Later on X.com, Tory Bruno stated, “All missions have propellant reserves. We add to that additional propellant margins based on the mass [and] the configuration of the rocket. Because this was compensated for within reserves, this anomaly was ‘invisible’ to the rocket.” Bruno credited “Robust design and well engineered avionics” for the resilience of Vulcan, and indeed, it is one of the very few rockets launched that had an SRB failure and still successfully completed their mission.
Launch Replay
Video starts at t-minus five minutes.
Next Launch:
The next launch from Florida is a tricky call: SpaceX and the FAA have “paused” Falcon family launches while the company investigates issues with Falcon 9s second stage — there was an “off-nominal” performance of the Crew 9 second stage after the astronauts had separated from the launch vehicle when the stage was relit to de-orbit and reenter Earth’s atmosphere.
At this time, SpaceX has not announced a return to flight for Falcon rockets, and the FAA has not yet released a safety determination on the Crew 9 event that would allow SpaceX to resume flights.
Both of those could come at any time, however, and given the short stand-downs earlier in the summer with other Falcon issues, odds are good that this delay will be shorter rather than longer.
Should SpaceX announce Falcon 9 returning to action, its next scheduled launch is for the European Space Agency and the Hera mission. According to ESA, “As part of the world’s first test of asteroid deflection, Hera will perform a detailed post-impact survey of the target asteroid, Dimorphos – the orbiting moonlet of a binary asteroid system known as Didymos.”
“Now that NASA’s DART mission has impacted the moonlet, Hera will turn the grand-scale experiment into a well-understood and repeatable planetary defence technique. Demonstrating new technologies from autonomous navigation around an asteroid to low gravity proximity operations, Hera will be humankind’s first probe to rendezvous with a binary asteroid system and Europe’s flagship Planetary Defender.”

Weather
The 45th Weather Squadron has listed a 20% Probability of Violation for tomorrow’s launch, which means that the weather is expected to be 80% GO at launch time.
Payload
In this case, the mission is the payload.
CERT-2 is designed to be the second and final demonstration flight of Vulcan. The key objective for CERT-2 is to validate the performance of the Vulcan rocket and to demonstrate to the Department of Defense that the Vulcan flight system is ready for national defense and surveillance payloads.
