Launch-site satellite map
Coordinates come from the current launch record. This map shows launch pads, not a flight trajectory or viewing prediction.
Upcoming missions
Recent results already available in cache
Only completed records already fetched by the site are shown. This is a partial archive; an absent result does not mean the launch failed. No extra archive API requests are made.
Schedules are refreshed through the existing shared cache. Normal feed records may omit webcast, booster or timeline details; open the existing mission-details page to check its fuller source record. Saved calendar entries do not update automatically when a launch moves.
Mission details
RISAT-1B is the third in the series of radar imaging RISAT-1 satellites of ISRO using an active C-band SAR (Synthetic Aperture Radar), providing all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, in addition to military surveillance. The RISAT-1 series is developed, manufactured and integrated by ISRO. The 3-axis stabilized spacecraft bus consists of a hexagonal prism shape build around a central cylinder. Most of the spacecraft subsystems and the payload are integrated in the prism structure and the central cylinder. The solar panels and some subsystems are mounted on the cube-shaped section of the spacecraft.
Current status: Either the launch vehicle did not reach orbit, or the payload(s) failed to separate.

Launch time, window and countdown
The displayed local time is converted by your browser from the published international timestamp. Spaceflight schedules frequently use terms such as NET (No Earlier Than), TBD or broader day/month targets. Spaceflight Now explicitly distinguishes NET and TBD on its public schedule, and NASA also publishes launches with labels such as “No Earlier Than” and “Under Review.” For that reason, this page shows the upstream time precision instead of treating every date as equally firm.
Use the Next Rocket Launch page for the nearest mission, or compare more missions on the launches this week page. If a countdown reaches zero, confirm the operator’s live coverage before assuming liftoff occurred; holds and scrubs can happen very late in the sequence.
Rocket and launch site
PSLV XL is listed for this mission with Indian Space Research Organization. The current launch record places the mission at Satish Dhawan Space Centre First Launch Pad · Satish Dhawan Space Centre, India.
India has two launch pads at the site. The First Launch Pad, operational since 1993, is used for Polar Satellite Launch Vehicle, Small Satellite Launch Vehicle and formerly used by Geosynchronous Satellite Launch Vehicle.
Launch pads and ranges matter because azimuth restrictions, overflight safety, recovery zones and target inclination can constrain when and how a mission flies. Browse the Rocket Launch Sites page to compare other active locations represented in the upcoming schedule.
After liftoff: continue tracking
If this mission deploys Earth-orbiting spacecraft, they can appear later in Recently Launched Satellites once public orbital elements are available. For spacecraft travelling beyond Earth orbit, use the Deep Space section. The launch event and the later orbital catalogue are separate datasets, so payload tracking may not be available immediately after liftoff.
Sources and schedule caveats
Launch schedule data and associated imagery on this page come from Launch Library 2 / The Space Devs and are cached server-side by SpaceTracker.live. Schedule records can change as providers update readiness, weather, range coordination or mission constraints.
