Satellite operator Viasat is calling for a stop to all SpaceX Starlink launches...

SpaceX may face a legal challenge from a rival satellite operator who has called for a halt to Starlink launches pending an environmental review of the megaconstellation.

Broadband firm Viasat called on the US Federal Communications Commission (FCC) on Friday to stay a license modification allowing for Starlink's expansion in low orbit.

The megaconstellation, which promises to offer high-speed internet access around the globe, presently numbers more than 1,600 satellites.

To reduce projected lag in the network, SpaceX requested the FCC approve a change to their original plans, bringing some 2,800 satellites into lower orbits. 

Viasat intends to make the case in federal court that the FCC needed to conduct an environmental impact assessment before giving the go ahead for this change.

The firm's stated concerns — which have been mirrored by scientists — include around how the Starlink constellation is affecting astronomical observations.

Other environmental worries include the megaconstellation's potential to increase orbital debris and pollute the atmosphere by means of disintegrating satellites.

The FCC's original license to SpaceX permitted them to establish a constellation of 4,409 Starlink satellites , with 2,825 at an distance of 684–808 miles (1,100–1,300 km) and another 1,584 at 342 miles (550 km), which are in low Earth orbit.

However, on April 27 this year, the commission approved an application from SpaceX to modify the license — moving the satellites in higher orbits down to 342 miles (550 km) and lowering the total planned number of satellites by one to 4,408.
