It’s been over a month since SpaceX launched its first batch of 60 internet-beaming satellites for the company’s massive Starlink initiative, and all but three of the satellites seem to be working as intended. Initially, SpaceX was able to communicate with all 60 spacecraft after launch, but eventually lost communication with three outliers. The uncommunicative trio will continue to orbit the Earth for a time, but will eventually get pulled down toward our planet by gravity, where they will burn up in the atmosphere.

The rest of the 57 satellites have been working as intended, according to the company. Forty-five of the satellites have raised their altitudes with their onboard thrusters and have reached their final intended orbits of 342 miles (550 kilometers) up. Five of the satellites are still in the middle of raising their orbits, and another five are undergoing additional systems checks before they raise their orbits. As for the remaining two satellites, SpaceX intentionally fired their onboard thrusters with the goal of crashing them into the planet’s atmosphere. There wasn’t anything wrong with those satellites — the company just wanted to test the de-orbiting process.

SpaceX 's first operational Starlink satellites are seen in space for the first time after Falcon 9 payload fairing jettison following launch on May 23 Prior Initially, SpaceX was able to communicate with all 60 spacecraft after launch , but eventually lost communication with three outliers.

That means that five total satellites are headed into a fiery grave. “Due to their design and low orbital position, all five deorbiting satellites will disintegrate once they enter Earth’s atmosphere in support of SpaceX’s commitment to a clean space environment,” SpaceX said in a statement.

These 60 satellites, launched on May 23rd, were just the first of nearly 12,000 satellites that SpaceX plans to put into orbit around Earth. The company received permission from the Federal Communications Commission to launch one batch of 4,409 satellites, followed by another constellation of 7,518. The spacecraft are meant to fly in a relatively low orbit above the planet and beam internet coverage to the ground below, providing service to all areas of the globe. The idea is to provide coverage to rural or remote areas, where laying fiber isn’t an option, as well as provide another internet service option to customers.

SpaceX postpones Starlink satellite launch again, for 'about a week'

SpaceX postpones Starlink satellite launch again, for 'about a week' A SpaceX launch already scrubbed once due to inclement weather was postponed again nearly 24 hours later on Thursday, this time for "about a week," in order to update satellite software and "triple-check everything," Elon Musk's rocket company said. The delayed mission is designed to carry into low-Earth orbit an initial batch of 60 satellites for Musk's new Starlink global internet service, a venture intended to generate cash for the rest of the billionaire entrepreneur's space exploration ambitions.

Last night's successful Starlink launch was a big one for SpaceX — its heaviest payload ever, weighed down by 60 communications satellites that will eventually be part of a single constellation providing internet to the globe. Devin Coldewey @techcrunch / 7 months .

At first , SpaceX was ready to talk with all 60 spacecraft immediately after launch , but eventually missing communication with a few outliers. The truth that three of the SpaceX Starlink satellites stopped conversation may spark much more concern among the house community.

The company will soon start using its fledgling Starlink constellation to stream videos and play high-bandwidth video games, in order to see just how much lag time there is in the service. But the company says it will also implement changes on future spacecraft based on this launch. “While we are pleased with the performance of the satellites so far, SpaceX will continue to push the operational capabilities of the satellites to inform future iterations,” SpaceX said in a statement.

The fact that three of the SpaceX Starlink satellites stopped communication may spark more concern among the space community. Some experts are already worried about how the constellation will contribute to the space debris problem. Currently there are 2,000 operational satellites in orbit around Earth, according to the latest figures from the European Space Agency, and the completed Starlink constellation will drastically add to that number. Such a boost could increase the risk of collisions of satellites in space, creating more debris that could further threaten other spacecraft. A study done by NASA argued that 99 percent of all of the satellites in these massive constellations must be taken out of orbit within five years in order to keep the risk of in-space collisions low. And if a company cannot communicate with a satellite, it cannot control the vehicle and take it out of orbit.

SpaceX launches first 60 satellites of its internet network

SpaceX launches first 60 satellites of its internet network SpaceX on Thursday launched a rocket carrying the first 60 satellites of its "Starlink" constellation, which is intended to provide internet from space and could one day number 12,000 satellites. One of the company's Falcon 9 rockets blasted off without incident from Cape Canaveral in Florida around 10:30 pm (0230 GMT). An hour later, the rocket began to release the satellites at an altitude of 280 miles (450 kilometers). The satellites then had to separate and use their thrusters to take up their positions in a relatively low orbit of 340 miles (550 kilometers).

California's SpaceX company has launched another 60 satellites in its Starlink network. It brings to 182 the number of spacecraft the firm has now put in the Two more batches of 60 could go up before the month is out, as the firm endeavours to start offering some regional broadband links later this year.

It’s been over a month since SpaceX launched its first batch of 60 internet-beaming satellites for the company’s massive Starlink initiative, and all but three Initially, SpaceX was able to communicate with all 60 spacecraft after launch , but eventually lost communication with three outliers.

However, SpaceX says it has implemented various design and system changes to ensure that the company doesn’t pollute the space environment. SpaceX CEO Elon Musk said that the Starlink spacecraft use data from the US Air Force on the positions of other satellites in space, in order to move out of the way and avoid collisions with nearby objects. And in April, the FCC approved SpaceX’s request to fly its initial batch of Starlink satellites closer to Earth, so that they would be dragged downward and fall out of orbit more quickly.

Astronomy experts are also concerned. Light and radio astronomers have raised concerns about how the Starlink constellation could affect observations of the Universe. When the first 60 satellites launched, the spacecraft turned out to be much brighter in the sky than anticipated, and scientists warned that the light reflected off these vehicles could mess up their long-exposure images of the sky. Additionally, radio astronomers were also suspicious that the frequencies that these satellites operate on could cross with the frequencies scientists use to study distant objects in space.

SpaceX says it has been working with leading astronomy groups to figure out ways to mitigate any potential impacts on space science. And top astronomy groups have put out statements saying that they have been in proactive talks with the company.

In the meantime, it’s unclear when the next launch of Starlink satellites will occur. Musk said the company will continue to launch batches of 60 satellites at a time, with the goal of getting between 1,000 to 2,000 spacecraft up each year. It should take about 24 launches to reach global internet coverage, according to Musk.
