Summary
Over the Pacific Ocean LIVE
Where is DS-SAR?
At on November 15, 2026, DS-SAR was over the Pacific Ocean (3.4° N, 147.7° E), 524 km up, moving at 7.6 km/s and in sunlight.
What is DS-SAR?
A satellite that watches the Earth in low Earth orbit, in space since Jul 30, 2023.
Can I see DS-SAR?
No, not with the naked eye: no brightness has been published for DS-SAR, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

From GCAT, Jonathan McDowell’s general catalogue, licensed CC BY 4.0: the operator, the state, the manufacturer, what it is for, that a defence organisation flies it, the launch day, the mass, and whether it is operating. The orbit class is read from its current elements.
In orbit
- Close approaches
- No close approach to DS-SAR has been reported publicly in the past thirty days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 14, 2026, 1:52 PM, 10 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.

In view from you
Nobody watches DS-SAR 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 DS-SAR, 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.
