Edgar Martins Explores the European Space Agency

Edgar Martins spent the past two years exploring the facilities of the European Space Agency (ESA) and photographing the weird, clinical spaces he came across. His project marks the first time in the ESA’s history that an artist has been granted exclusive access to the agency’s staff, programs, and technology. The resulting series looks like a mood board for the sequel to 2001: A Space Odyssey.

Born in the late 1970s, Edgar wasn’t a child of the space race, but he’s always been enthralled by the Apollo program. “I grew up wanting to become an astronaut—not an easy accomplishment for a European in communist China—and still have recurring dreams where I’m propelled into space, though can never remember how,” he says. “In the dream, I get into Earth’s orbit, float in zero G, look down at the planet for the first time from afar, and become overwhelmed with the experience.

"Space and all the mysticism and technological marvels that surround it have an immeasurable resonance on our social and individual consciousness. It’s a topic that constantly throws me, and us, into the antinomies of perception and existence, toward the exploration of boundaries and unstable geometries."

Space Station Science and NASA’s Flying Saucer

SciShow Space shares the latest news from around the universe, including a wrap-up of the experiments conducted in the last space station mission, a test of a new “flying saucer” device from NASA, and new life for our old friend, the Kepler Space Telescope!

The Lunar Landing Training Vehicle, and its predecessor, the Lunar Landing Research Vehicle, were developed by NASA in the early 1960s to prepare astronauts for the first mission to the moon. Built by Bell Aerosystems, the vehicles featured a GE CF-700-2V jet engine that pointed downward to cancel out 5/6th of the vehicle’s weight. Two 2250 Newton hydrogen peroxide lift rockets were also used to help simulate lunar conditions.

Three out of the five that were created crashed during training, with all of the astronauts, including Neil Armstrong in the first crash, ejecting safely. According to Armstrong, the Lunar Module flew better than the test vehicles, but the test vehicles were vital to the success of the moon landing. In his own words, “What the LLTV gave you was not so much the seat-of-the-pants dynamics as the real-world visual. That and the fact that, if you make a mistake, you can’t hit the reset button.”

Solar Flares and a Virtual Universe 

SciShow Space takes you inside solar flares, and how we’ve managed to get the best look at one yet, along with news about a new, Web-based simulation of the earliest days of the universe that you can explore yourself!


Japan’s plan for a solar collector in space in nothing new, however, if executed, it will be amazing.


That’s right. And before you preemptively speculate, this is not something new.

Space-based solar power generation has been proposed and feasible since the 60’s. However, you may have heard of recent proposals in the last few years, such as the U.S. Navy’s plan to beam down energy from orbiting solar panels, the Department of Energy’s developments via their Lawrence Livermore National Laboratory, Space Energy’s ambitious project for SBSP (space-based-solar-power) toward a clean energy market, Russia’s proposed plan regarding infrared energy receiving stations via an “infrared window, and the proposed collaboration between the China Academy of Space Technology (CAST) and the Indian Space Research Organization (ISRO) on an Space-Based Solar Power Initiative…to cite a few.


Space-based solar power (SBSP) is the concept of collecting solar power in space (using an “SPS”, that is, a “solar-power satellite” or a “satellite power system”) for use on Earth. It has been in research since the early 1970s. [source]

Although there is speculation behind everything due to the obvious history of humankind, let alone of the countries allocating such time to even put forth plans such as these which involve collaboration toward a monumental common goal for the greater good regarding the longevity of our species…one this is certain and blatantly obvious: ambivalence regarding fossil fuels and climate change is beyond irrelevant.

We can no longer entertain climate change deniers or wish away our carbon emissions. Action is needed, and the sun has been a thriving energy power plant blinding us with its raw power, while the physics have been awaiting our crawl out of carbon addiction to realize what we’ve known all along…anything unsustainable will ultimately be just that — not sustainable. It’s only been a matter of when. We must come up with the how, and there are a growing number of feasible options.


“The timing of the oil catastrophe is a great opportunity for re-evaluating solar energy from space.” - Former Astronaut Buzz Aldrin [read the blog post from the National Space Society]

The Japan Aerospace Exploration Agency has proposed an exciting Space Solar Power System, whereby sunlight is collected in geostationary orbit, converted into electromagnetic radiation via microwaves or laser beams, transmitted to a ground or ocean-based receiving facility for use as electricity and hydrogen for Earth use.

Questions? Read Practical-Application of Space-Based Solar Power Generation" from JAXA and the MOTHERBOARD | VICE editorial, which addresses such issues as Earth’s rotation…


The problem is that part of the Earth’s rotation spins it away from the sun, which doesn’t do much good for a solar power station. So the scientists hacked the initial model by adding in a couple mirrors to reflect the sunlight and point it directly on the panels, 24/7. These mirrors are just floating free, and scientists on the ground have to configure the whole setup with extreme precision. [source]

…and the storage of energy via solar stations on Earth.


The solar station is tethered to a base station on the ground with six-mile-long wires. This acts as a counterforce to offset the gravitational pull so the satellite is essentially pulled in tow as the Earth turns, keeping it at a fixed point in geostationary orbit. It’s the concept astrophysicists proposed to build our future space elevators, as explained Professor Emeritus at JAXA Susumi Sasaki in an editorial in IEEE. [source]

No matter what avenue is explored first, when it comes to sustainable energy, the future is indeed bright. Watch JAXA’s SBSP Systems video HERE.
