6/18 9 9:00 PM Update: with only a few minutes left in the countdown, SpaceX waved off their launch attempt of Falcon 9 carrying the Astra 1P television satellite designed to serve the European market once operational. Both the rocket and the payload are in good condition, and weather permitting, another attempt is expected as soon as late tomorrow afternoon.

SpaceX has updated the launch schedule: “SpaceX is targeting Wednesday, June 19 for a Falcon 9 launch of the SES ASTRA 1P mission to geosynchronous transfer orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The two-hour and 49-minute launch window opens at 5:25 p.m. ET.”

SpaceX is targeting a Falcon 9 launch of a television communications satellite to geosynchronous orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida this evening.

SpaceX plans to launch Falcon 9 carrying the Astra 1P satellite this evening from Space Launch Complex 40. The launch window opens at 5:25 PM EDT and extends to 8:24 this evening. Florida being Florida, it’s a coin flip regarding the weather.

The Automated Spaceport Drone Ship ‘Just Read the Instructions’ (JRTI) will be stationed downrange in the Atlantic Ocean to recover the booster after its job is finished.

There will be no sonic booms over the Space Coast.

Payload

Built by Thales Alenia Space, Astra 1P is a television satellite that will serve the pan-European market once operational. It is the most powerful wide-beam satellite to ever orbit at 19.2 degrees East. It offers up to 80 physical transponders with bandwidth filters and can carry up to 500 high-definition stations to roughly 119 million homes in its target markets.

Astra 1P was ordered in November 2021 (along with Asra 1Q). It is based on the Thales SpaceBusNEO platform and intended to replace three satellites. It is planned for about fifteen years of use.

Trajectory

Generally eastwards. The Astra 1P satellite’s destination is GEO to 19.2 degrees East in a geosynchronous equatorial orbit (GEO), roughly 35,786 km (22,236 mi) above the Earth.

The Automated Spaceport Drone Ship ‘Just Read the Instructions’ (JRTI)’ will be stationed downrange in the Atlantic Ocean to recover the booster after its job is finished. As such, there will be no sonic booms over the Space Coast as a result of this launch.

Weather

Weather is a coin-flip. According to the 45th Weather Squadron, a prolonged “Onshore flow creates blustery conditions and ample low-level moisture for cumulus cloud and isolated shower development. Wind speeds may reach 25mph on the primary day, making Liftoff Winds and Cumulus Cloud Rule violations the primary concerns for tomorrow’s launch attempt.”

Booster: B1080

According to SpaceX, the booster that is being used for this mission, “This is the ninth flight of the first stage booster supporting this mission, which previously launched Ax-2, Euclid, Ax-3, CRS-30, and four Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.”

That’s Booster B1080. It last flew a roughly four weeks ago when it sent Starlink 6-62 to orbit late last month.

Online Launch Viewing

SpaceCoastLaunchCalendar.com will have a livestream of the launch if you’re not able to watch the launch in person: Livestream

SpaceX will have a livestream of the launch on their website: Astra 1P Mission Page. This will also be available on the X platform. Coverage starts about fifteen minutes before liftoff.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

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.

Next Space Launch an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play.

Launch Viewing: In Person

This morning’s planned launch is from SLC-40, on the south side of the Eastern Range (KSC and Cape Canaveral Space Force Station combined.) The southern parks in Titusville on Washington Avenue and FL-528/A1A in Cape Canaveral are the best spots to watch liftoff directly.

• Banana River Bridge on FL-528 W in Cape Canaveral
• Kennedy Point Park in Titusville
• Rotary Riverfront Park in Titusville

Restaurants With Good Launch Views

Given the early hours of the launch window (7:30AM – 11:30AM EDT) these restaurants may not be open for launch viewing. Later in the day, all three may well be, so if you are interested, be sure to call ahead to make sure they’ll be ready to serve you.

• The Space Bar ($$$) – atop the Courtyard Marriott near Kennedy Parkway
• New York New York ($$) – on the Indian River with an outdoor seating area. Is family-friendly.
• Shiloh’s ($$$) — located on the Indian River with an outdoor deck overlooking KSC/CCSFS

Indirect Views

There are several excellent viewing spots for SLC-40 launches that offer indirect views — meaning you won’t see the rocket until it clears obstructions such as trees, buildings, even a storm berm in one case.

• Jetty Park, Port Canaveral
  • Fee required, much be purchased in advance: Port Canaveral Store
  • It’s very possible to see a cruise ship coming or going.
  • The pier especially has great views
• Cocoa Beach
  • Parking fees (probably). Pay with your smartphone on the parking app. There are signs everywhere telling you how.
  • Further away, but still good views.
• Northern Titusville Parks
  • Further away, but really nice views.

Playalinda Beach

Playalinda Beach out on the Cape Canaveral National Seashore will be open to spectators until 8 PM EDT, that is if KSC Security and the National Park Service allow viewers for the launch. It opens to visitors at 6 AM.

Call ahead to be sure.

Cape Canaveral National Seashore • Playalinda Beach
Phone: (386) 428-3384 x0
Current operating hours: 6:00 AM–8:00 PM

If you are going to Playalinda, and if it is open, remember these general tips. Some may not apply to this particular launch.

• Get there at least two hours early, or better, earlier than that. Lines are long at the entry gate and they will only allow as many spectator vehicles as there are parking space available.
• If the launch L-0 time is moved to after 8PM, you must leave Playalinda, as the National Park Service is very strict about closing hours.
• Cape Canaveral National Seashore has a fee to get in and cash is not accepted. Debit and credit cards are okay, or if you have one of the National Park Service’s passes for the Seashore or the National Parks, that will work as well.
• Cellphone service is spotty at best and often non-existent at Playalinda. Don’t count on your cellphone to keep up with the launch; you might get a signal, or you might not.
• You are not allowed to view from the pullouts on Beach Road. Stanchions will block them. You’ll have to park and go to the beach.
• Refreshments are not available. There are no stores at Cape Canaveral National Seashore, so you’ll need to bring drinks and food if you want any while you’re there.
• Rangers will keep you back a certain distance from the launch area on the beach. Even if the beach is open, you’ll still be unable to go down to the fence that demarcates the normal security zone. There’s a line that spectators can’t go past somewhat north of the fence. That’s for safety and security.
