This is a replacement satellite for the Indian Regional Navigation Satellite System. The constellation will provide India with an alternative to GPS and will be used for military and civilian use. Located at a geosynchronous orbit, the system will be operated by the Indian government.

Synthetic aperture radar Earth observation satellite for Japanese Earth imaging company iQPS.
Low Earth Orbit communication satellites with Ku, Q and V band payloads for the G60 constellation operated by Shanghai Spacesail Technologies with funding backed by the Shanghai local government. Initial constellation will consist of 1296 satellites by 2027 with long term plans to expand it to 12000 satellites.
A classified mission for the United States Space Force. It is possibly a batch of classified LEO satellites based on SpaceX’s Starshield satellite bus, based on locations of rocket stage drop zones being exact fits with previous Starlink Group 15 launches.
Note: Launch vehicle name is provisional. First orbital full version launch of the South Korean military small satellite launch vehicle, after 2 sub-orbital tests of individual stages on 30 March and 30 December 2022, and 1 orbital test flight without the 2nd stage on 4 December 2023. Details TBD.
The briefing · The week ahead
The next mission we are following closely is GSLV Mk II | IRNSS-1L (NVS-03), a GSLV Mk. II flight operated by Indian Space Research Organization from Satish Dhawan Space Centre Second Launch Pad, Satish Dhawan Space Centre, India, currently listed for . The provider currently labels it Go. Read that as readiness, not as a promise — weather, the vehicle and the launch range all keep a vote until the count is over.
The board below currently tracks 20 upcoming missions from 10 different operators, and the honest way to read it is to separate three things the cards show side by side: the target time, how precise that time claims to be, and the reported status. The mission nearest the top is not automatically the firmest one — a day-precise target with a confirmed status is a viewing appointment, while a month-level estimate is a campaign to keep an eye on. That distinction, more than the countdown itself, is what decides whether a launch is worth planning an evening around.
Missions we select for coverage are marked Featured, and their cards carry the broadcast link when a live stream is scheduled. If you are new to launch watching, the timing section of the field guide below explains windows and “no earlier than” in plain language, and the viewing guide covers official broadcasts, time zones and what the milestones after liftoff actually prove.
01 / Start with the mission
The useful question is not just “When is the next rocket?” It is “How firm is this time, and what should I check before I watch?” Spaceflight Tracker brings the target date, its precision and the reported status together so you can make that distinction.
Start with the mission name and the launch site. A rocket family can fly several missions close together, and a broadcast with the right vehicle name can still be for the wrong flight. The operator is the organization providing the launch; it is not necessarily the organization that owns the satellite. The mission brief identifies the payload when the source provides it.
Read the status separately from the time. A precise timestamp can coexist with an unconfirmed schedule. Equally, “Go” describes the provider’s readiness label; it is not a promise that weather, equipment and the launch range will all remain ready. The calendar sorts by target date so a nearby tentative mission is not silently moved behind a later confirmed one.
Mission and site → date precision → status → operator’s latest announcement. If any of these disagree, resolve the disagreement before treating the time as an appointment.
02 / Read the clock carefully
“No earlier than,” often shortened to NET, is the currently listed earliest target. A launch window is the interval in which the flight can depart and still meet its mission constraints. The geometry of the destination and Earth’s rotation help determine that opportunity. Some flights have a window spanning a period of time; others have an instantaneous opportunity. Missing that opportunity can mean waiting for a later attempt. NASA explains the orbital geometry behind launch windows.
The provider also supplies a precision field. A month-level estimate should be read as a planning horizon, even if the underlying database stores a full date and time. This site suppresses the clock for estimates that are not precise to the minute or second. When precision is missing, it labels that uncertainty instead of assuming the stored timestamp is exact.
Suppose a target is 00:30 UTC on 18 September. For a viewer at UTC−3, that is 21:30 on 17 September: subtracting three hours changes the calendar day. A reminder for the evening of the 18th would be a day late. Use the local-time switch on the schedule and check both the date and the zone.
A clock passing the target only means the listed time has passed. It cannot tell you whether engines ignited, the count held, or the flight was postponed. The status must come from a later report. This is why an elapsed target is labelled as awaiting confirmation rather than automatically becoming a successful launch.
03 / Turn the listing into a viewing plan
NASA’s countdown rehearsal description explains that holds can be built into a timeline to allow checks and align the count with the launch window. An unplanned pause can look similar to a viewer, so the broadcast commentary matters more than a timer running on a separate website. See NASA’s explanation of countdown holds.
For an in-person visit, make a separate plan for the viewing location. A launch site on a mission record is not a public access point. Confirm opening hours, ticket conditions, closures and permitted viewing areas with the venue. Keep transport and accommodation plans flexible; this schedule is not a travel guarantee.
04 / Know what you are watching
A broadcast can show a spectacular departure without yet establishing whether the payload reached its intended orbit. Keep the launch vehicle’s progress, any booster recovery and the payload’s deployment separate in your notes. They answer different questions about the flight.
| Milestone | What to check next |
|---|---|
| Liftoff | The flight has started. Wait for ascent and spacecraft updates before describing the mission as complete. |
| Stage separation | Follow the upper stage carrying the payload. A returning booster may appear in a separate camera view. |
| Engine cutoff / coast | Look for the planned flight sequence. A coast may precede another burn; silence is not itself evidence of a problem. |
| Payload deployment | Check what the operator confirms about separation and the achieved orbit. A spacecraft can still have commissioning tasks ahead. |
There is no universal minute-by-minute sequence for all vehicles. For example, NASA’s published Cygnus CRS-5 timeline distinguished first-stage cutoff, separation, second-stage ignition, orbit insertion and payload separation. Use the actual mission timeline to interpret an individual flight.
Launch dates, mission descriptions, status labels and available video links come from The Space Devs’ Launch Library 2. They are cached for 30 minutes, so operator announcements may be newer. A missing feed is shown as unavailable; it is never replaced with demonstration missions. API documentation describes the underlying records.

It does not claim independent flight reporting or a manual check of every live record. The linked NASA examples explain launch concepts, not the status of today’s flights.
