Steven's Launch Guide

Steven Madow Photography

About this app

Watch, or photograph, a rocket launch in person on Florida's Space Coast. I'm Steven Madow, a NASA-credentialed photographer of 250+ launches. I built this so you don't have to learn it the hard way like I did: where to stand, whether it's worth the drive, and when and where to look.

Launch day, start to finish:

T−7 days · Know what's launching
• Every launch from Cape Canaveral and Kennedy Space Center, with a live T-minus
• Honest times: if only the day or month is known, that's all you'll see
• CONFIRMED when T-0 is firm, GO only when the launch team actually polls GO
• Holds and scrubs as they happen, with the reason and the new time
• Follow what you care about: reminders, slip and scrub alerts, and auto-follow for every Space Coast launch, crewed flights, Falcon Heavy, New Glenn, or any rocket or provider

T−2 days · Decide if it's worth the drive
• Worth the drive? One read that weighs the weather, the launch window, and how this rocket has been doing
• Steven's Outlook: my own read on launch weather, given as a range, with the rules that could stop it
• The backup days side by side, in case it slips
• Track record: how many of this rocket's last ten launches went on the first try

T−1 day · Be in the right place
• Hand-picked viewing spots with photos, distance to the pad, which way to face, and directions
• Spots closed for a launch are left out (no driving to the LC-39 gantry for a 39A launch)
• Will Playalinda be open? Park Service notices tied to each launch, and a push when it's confirmed
• A heads-up when a twilight launch could make a "jellyfish" plume

T−8 hours · Sleep, it's watching the range
• A big Countdown Clock widget for your nightstand that says if the launch scrubs
• A wake-up alarm set from liftoff: it rings through silent mode, moves if the launch slips, and turns off if it scrubs. No 4 AM wake-ups for nothing

T−3 hours · Know if you'll see it
• Launch-weather odds and the rules forecasters are watching
• Clouds at T-0 split into low, mid, and high layers, with a plain-English verdict
• Live NOAA satellite and NEXRAD radar loops over the pads

T−1 hour · In your notifications
• A live countdown notification starts an hour before launches you follow
• After liftoff it keeps counting to each booster burn and the landing

T−10 minutes · Point at the pad
• A live compass: turn until the arrow lines up and that's where it rises
• Calibrate it against the Sun, the Moon, or a landmark

T−0 · Eyes up, not on your phone
• Spoken callouts: T-minus milestones, the final ten, "Liftoff!", Max Q, and engine cutoff
• Warnings 30 and 10 seconds before boostback, entry, and landing burns
• Keeps talking with the screen off, through earbuds or out loud from the phone
• A full-screen countdown mode that turns sideways on a tripod
• Works without a signal: the next few launches are saved on your phone, and the callouts keep going

T+8 minutes · Then watch it come home
• Countdowns to every booster burn and the landing, for all three Falcon Heavy cores
• Landing zone or droneship, and sonic boom heads-ups when it's coming back to the Cape
• Results the moment they're known

T+2 days · Watch the droneship come home
• Follow the droneship back to port, with the booster on deck
• How far along it is and roughly when it'll be in
• An alert when your booster is coming home, so you can be at the jetty when it sails in

Keep a launch log
• Log every launch you saw in person or watched on the stream, and where you watched from
• Earn badges, and add your past launches in a couple of taps
• My recap of launches I photographed, with my photos and prints from that launch

Know the mission
• Booster history, pad turnaround, and "by the numbers" stats
• What's on board, mission patches, and infographics
• Crew, spacecraft, and the full countdown timeline

What’s new

New: add launches to your phone's calendar, live Jetty Park closures, cloud maps with the launch window, and droneship arrivals with support ship and tug hints. Also: a check before setting an alarm, clearer holds and scrubs, "Just flew" after liftoff, search fixes, and many smaller fixes.
