Hubble’s Orbit Has Dropped So Far that Starlink Satellites are Photobombing its Images

Astronomy is poised for another leap. In the next several years, major ground-based telescopes will come online, including the Extremely Large Telescope (ELT,) the Thirty Meter Telescope (TMT,) the Giant Magellan Telescope (GMT,) and the Vera Rubin Observatory. The combined power of these telescopes will help drive discovery in the next couple of decades.

But something threatens to undermine astronomical observing in the coming years: Starlink and other internet satellite constellations.

Now a group of astronomers have shown that even the Hubble can’t escape the satellite problem.

Many of the World’s Greatest Observatories Suffer from Some Light Pollution

In a recent study published in the Monthly Notices of the Royal Astronomical Society, an international team of researchers examined the levels of light pollution at astronomical observatories from around the world to better understand how artificial light is impacting night sky observations in hopes of taking steps to reduce it. But how important is it to preserve the scientific productivity of astronomical observatories from the dangers of light pollution, as noted in the study’s opening statement?

BlueWalker-3 Unfolds, Brightens One-Hundredfold

After months of waiting, we’re getting our first good looks at a fully deployed BlueWalker-3.

A new high-profile satellite may now be visible in a sky over you. We recently wrote about AST Space Mobile’s new BlueWalker-3 satellite, and its potential to be among the brightest objects in the night sky. Launched on September 10^th, 2022 an a SpaceX Falcon-9 rocket along with the Starlink Group 4-2 batch, BlueWalker-3 is the first of the company’s planned mega-constellation of 110 BlueBird satellites set to be deployed by the end of 2024 for worldwide communication.

Scientists in Antarctica Have Access to Starlink Now. It’s Available on 7 Continents

SpaceX’s Starlink service is now available in Antarctica, according to a tweet from the National Science Foundation on the morning of September 14, stating, “NSF-supported USAP scientists in #Antarctica are over the moon! Starlink is testing polar service with a newly deployed user terminal at McMurdo Station. Increasing bandwidth and connectivity for service support.” SpaceX replied with a quote tweet saying, “Starlink is now available on all seven continents! In such a remote location like Antarctica, this capability is enabled by Starlink’s space laser network.”

BlueWalker-3 Satellite Launches This Weekend, May Be Bright

A new satellite launching this weekend BlueWalker-3 could be conspicuously bright once it’s unfurled in orbit.

A routine SpaceX Starlink launch this coming weekend carries an unusual passenger, that you many be able to easily see gliding through the increasingly crowded night sky.

You’ll Soon be Able to Access Starlink Directly With Your Cellphone, From Anywhere in the US, and Eventually the World

The future of satellite communications is almost upon us. SpaceX has signed a deal with T-Mobile to provide the carrier’s customers with text services from its Starlink satellites anywhere in the US starting next year.

With Better Communication, Astronomers and Satellites can co-Exist

SpaceX’s Starlink satellite system has been in the news lately for both good and ill. The “Mega-constellation” of around 2,800 satellites added another 53 satellites to its roster just last week. But while it might one day provide high-speed internet for the whole of humanity, it is already causing a massive headache for one particular slice of humanity – astronomers. Starlink satellites are reflective due to the solar panels they need to power themselves.

Starlink Satellites Are Still Bright

The new generation of Starlink satellites remain above the accepted brightness threshold.

It’s one of the stranger sights of the modern Space Age. Recently, we found ourselves under the relatively dark skies of southern Spain. Sure enough, within a few minutes, we caught sight of a chain of flashing ‘stars’ winking in and out of view in quick succession.

SpaceX Shares an Image of the Super Heavy Booster Bristling With 33 Newly Installed Raptor Engines

Not long ago, SpaceX passed their Programmatic Environmental Assessment (PEA) with the FAA, though many corrective actions were recommended. With this hurdle in its rearview mirror, SpaceX is busy preparing the Starship and Super Heavy prototypes for their orbital test flight. On Saturday (July 2nd), the company posted pictures on its Twitter feed that showed the Starship (SN24) and Super Heavy booster (BN7) outfitted with all the Raptor engines – 33 Raptors for the BN7, 6 for SN24 – that will take them to space.

Starlink is the Only Communications Link for Some Ukrainian Towns, but the Terminals Could Also be a Target

Russia’s invasion of Ukraine has led to an outpouring of support and material aid from the international community. For his part, Elon Musk obliged Ukrainian Vice Prime Minister Mykhailo Fedorov‘s request for assistance by sending free Starlink terminals to Ukraine. For some besieged communities, like the city of Mariupol, this service constitutes the only means of getting up-to-date information, communicating with family members, or sharing their stories from the front lines of the war.

Mykhailo Fedorov, Ukraine’s Vice Prime Minister and its Minister of Digital Transformation, thanked Musk on Twitter for the devices. However, there is also the possibility that as the fighting continues, Starlink transmissions could become beacons for Russian airstrikes. John Scott-Railton, a senior researcher with The Citizen Lab (University of Toronto), pointed out this potential danger via Twitter and even recommended strategies for how this can be avoided.
