Space Telescope App
Webb, Hubble, Roman, ISS
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Space Telescope is an astronomy app for people who actually go outside and look up.
See what the James Webb Space Telescope is observing right now. Decide whether tonight is worth staying out for. Catch the next visible ISS pass over your own location, and follow the rocket launches coming up.
WHAT WEBB IS LOOKING AT, RIGHT NOW
Webb's current target, science category, proposal, instruments and scheduled times, refreshed every five minutes while the view is open. Tap through to the proposal or the full observation schedule.
A REAL PLAN FOR METEOR NIGHT
Most meteor apps hand you a peak date. This one tells you what you will actually see. Set your location and how dark your sky is, and get an honest meteors-per-hour range, the best viewing window, where to look, how much the Moon will wash out, and what 30, 60 or 90 minutes outside is likely to be worth.
Two alerts that matter: a heads-up the evening before, and a nudge when your window opens. Cloud cover is not included, so check the weather before you commit.
THE ISS, OVER YOUR HOUSE
Live position, altitude, velocity and orbit, plus crew, expeditions, dockings and visiting vehicles. Seven days of passes for your location with quality, direction, peak elevation and duration - set a 10-minute alert or drop the pass straight into your calendar.
LAUNCH DAY
Upcoming launches with live countdowns, status, provider, rocket, pad, launch window and webcast link. One tap for a reminder 15 minutes before liftoff.
GALLERIES WORTH SCROLLING
Imagery and mission guides for James Webb, Hubble, Chandra, the Nancy Grace Roman Space Telescope, Artemis, Mars and the ISS. Follow Roman's countdown, instruments and journey to L2. Pinch to zoom, save, share, like and comment. Turn on alerts only for the galleries you care about.
PICTURE OF THE DAY
NASA's Astronomy Picture of the Day, image or video, with the full expert explanation and an optional daily alert.

Set your observing location by searching for any town or city, and see its real place name instead of "Your location".
Your location is now shared across Meteor Showers, Tonight's Sky and ISS Passes, so you only set it once.
Also fixed: very large images no longer crash the zoom viewer, premium wallpaper downloads now explain why they failed, and a download could get stuck loading forever.
