In view from you
Nobody watches NISAR go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for NISAR, so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to go outside for: it is too faint for the naked eye. What it is up there for reaches the ground as pictures and measurements, not as a light in the sky.
Altitude
One reading a day, worked out from the elements Space-Track publishes.

Summary
Over Canada LIVE
Where is NISAR?
At 3:01:30 AM UTC NISAR was over Canada (51.3° N, 124.4° W), 758 km up, moving at 7.48 km/s and in sunlight.
What is NISAR?
A satellite that watches the Earth in low Earth orbit, in space since Jul 30, 2025.
Can I see NISAR?
No, not with the naked eye: no brightness has been published for NISAR, and nothing here estimates one; what people use is its pictures and measurements of the Earth.
General
- Launched
- Rocket
- GSLV
- Watches
- The land and the ice, by two radars that see through cloud and darkness: ground and glaciers moving by a centimetre, forests and crops

- Operator
- ISRO, which flies it, and NASA, which plans its radar observations: the two agencies’ first satellite together
- Mass
- about 2.4 t

No operator publishes an ephemeris for NISAR, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to NISAR has been reported publicly in the past thirty days.
- Losing to drag
- NISAR has not fallen measurably over the last 48 days of samples.
From Space-Track’s public conjunction messages; the latest report was issued Nov 2, 2026, 1:53 PM, 13 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
