Look out, space billboards could be coming to a sky near you

It’s an idea that will send a shiver down the spines not only of astronomers who need clear skies to do their work, but also of regular folks who sometimes like to gaze dreamily toward the heavens to immerse themselves in the beauty of the universe.

We’re talking about space ads. Space ads created by constellations of small satellites.

Having already agreed that the technology now exists for such a venture, researchers at Moscow’s Skolkovo Institute of Science and Technology (Skoltech) and the Moscow Institute of Physics and Technology recently conducted a study to determine the economic feasibility of a space ad mission involving a constellation of sun-reflecting satellites that can take up different positions to create images or words in the skies above cities.

To work out if the idea is a realistic possibility or a desperate waste of money, the researchers took into account satellite fuel consumption, target city population, and local ad costs, among other factors, and came up with a cost of $65 million for an entire mission lasting several months.

Additional research found that daily ad revenue from space ads could reach around $2 million, suggesting the operator could recover its costs within the space of a month if they display the ads on a daily basis, whether over the same city or by moving between different ones.

“We’ve been studying some of the more technical aspects of space advertising for a while now,” the study’s first author Shamil Biktimirov, a research intern at Skoltech’s Engineering Center, said in a release. “This time we looked at the economic side of things and, as unrealistic as it may seem, we show that space advertising based on 50 or more small satellites flying in formation could be economically viable.”

The idea for satellite-powered space billboards has been around for a number of years but, in light of this latest research, they now seem a step closer.

This is certain to alarm astronomers, many of whom have long been complaining about how reflections from SpaceX’s growing constellation of Starlink internet satellites can obscure their view of the night sky.

The researchers address this issue in their paper, claiming the concerns are unwarranted as the satellites would only reflect light for their messages around sunrise or sunset — and not at night when stars appear to blaze brightest.

The idea is also certain to disappoint anyone who rather enjoys gazing skywards to marvel at star-filled skies, a hobby that would almost certainly lose the fun factor if every time you spot a star constellation, a McDonald’s ad for a Happy Meal suddenly drifts into view.

Asimov’s vision of harvesting solar power from space could become a reality
Simplified diagram of space solar power concept..

It's an idea straight out of science fiction: A space station orbits around Earth, harvesting energy from the sun and beaming it down to our planet. Isaac Asimov popularized the concept in his 1941 story Reason, and futurists have been dreaming about it ever since.

But this notion is more than just an idle fantasy -- it's a highly practical concept being pursued by space agencies across the world, and it's almost within reach of current technologies. It could even be the solution to the energy crisis here on Earth.

Surreal video shows SpaceX rocket booster coming home
A SpaceX Falcon 9 booster returning to Earth.

SpaceX spent years developing a spaceflight system that enables it to reuse the first stage of its Falcon 9 booster.

It does this by landing the booster upright just minutes after it has deployed the rocket’s second stage. After that, it’s checked over, refurbished, and sent out for another mission. Some of SpaceX’s Falcon 9 boosters have made nearly 20 flights, and other parts of the vehicle, such as the Crew Dragon spacecraft and the fairing, can also be used for multiple missions.

Astronomers are figuring out what causes incredibly bright flashes in space
In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in green) can influence the flow of electrically charged material from the object, which is a type of neutron star.

Some of the oddest cosmic phenomena are short but tremendously powerful bursts of radio waves, which, in a fraction of a second, can give off as much energy as the sun does in a year. Known as fast radio bursts, these incredibly bright flashes of energy are thought to be related to dying stars called magnetars. Now, using two separate telescopes, astronomers have observed one of these events just a few minutes before and after it occurred, giving the best look yet at what causes these strange events.
