SpaceX have began launching a new set of Starlink satellites which will eventually create a ‘shell’ of near-polar communications satellites which are capable of serving few of remote customers on Earth. And thats name Polar starlink satellites
Starlink Group 3-1
Also Known as Starlink Group 3-1, this mission was also SpaceX’s 50th mission which is dedicated to Starlink launch since the companys first launched with a full batch of prototype satellites in the month of May 2019.
Just after three years later, SpaceX’s Starlink constellation is responsible for mainly half of all working satellites currently in the Earths orbital – a figure which is likely to continue to develop for the indefinite future.

Falcon 9 which lift off from the SpaceX’s Vandenberg Space Force Base (VSFB) SLC-4E pad at 6:39 pm PDT in the month July 10th carrying 46 Starlink V1.5 satellites –which is a payload of around 14 tons (~30,000 lb). SpaceX reduced the total number of satellites from the usual 53 to the account for their mission’s unusual (relative to Starlink) trajectory and for the target orbit.
Instead of the casual dozens of missions to a partially ordinary 53-degree orbit around theEarth’s mid latitudes and around the equatorial regions, Starlink 3-1 is the first of several planned missions which is planned to a near-polar orbit in which satellites will cross the Earth’s equatorial plane at an integral angle of 97.6 degrees
It isn’t SpaceX first near Polar Orbital Launch-
This orbit is technically slightly retrograde or can say opposite to the direction of Earth’s rotation, which conveys that Starlink Group 3 launches will have to work opposite to Earth’s rotation – which is a bit like trying to climb the wrong escalator.
Actually It isn’t SpaceX’s first Starlink launch to a near-polar orbit: the company have technically launched alomost 15 Starlink prototypes to the variety of moderately different sun-synchronous orbits which are very fimilar to Starlink 3-1’s target.
SpaceX also launched a integrated single batch of Starlink Group 2 satellites to intergal 70-degree semi-polar shell in the month September 2021. This purpose of the 51 Starlink 2-1 satellites – in which only 19 of appear to be an operational – which is unclear, though, and their are only 3 of the other 15 prototypes which are still in orbit
As a result, the Group 3 could become the first polar Starlink ‘shell’ to actively enter general service. SpaceX which is already have plans for a second Group 3 launch – Starlink 3-2 – as early as in the end of month July, and at 46 satellites apart, as few as their are eight launches will be needed to complete the 348-satellite shell.
FCC gives SpaceX permission-
When the US Federal Communications commission (FCC) provide SpaceX permission to activate the thousands of intersatellite laser links which are installed on the ~1000 Starlink V1.5 satellites which are already in orbit, the new polar shell may even allow Starlink to connect with the planes, ships, or outposts that which are hundreds or thousands of miles apart from the nearest ground station.
A two-stage Falcon 9 rocket comes with 46 oSpaceX’s Starlink internet satellites which lifted off from California’s Vandenberg Space Force Base on the last Sunday at 9:39 p.m. EDT (6:39 p.m. local California time; 0139 GMT on July 11).
