The growing problem of space debris in LEO (Low-Earth Orbit) is garnering more and more attention. With thousands of satellites in orbit, and thousands more on the way, our appetite for satellites seems boundless. But every satellite has a shelf-life. What do we do with them when they’ve outlived their usefulness and devolve into simple, troublesome space debris?

Ever since it started taking to space, there has been a lot of mystery and controversy surrounding the USAF’s X-37B space plane. Despite the fact that this militarized-version of NASA’s orbital vehicle has conducted several spaceflights since its first in 2010, we still have no idea what its true purpose is. But so far, the smart money appears to be on it being an advanced spy plane.
Hoping to gather clues to this question, skywatcher and satellite tracker Ralf Vandebergh of the Netherlands has spent the past few months hunting for this space plane in the night sky. Recently, he was fortunate enough to not only locate the elusive X-37B in the sky but also managed to snap some photographs of it. Given its diminutive size and secretive-nature, this was no small feat!

It’s easy to take for granted the detailed, almost real-time knowledge of Mars that we have at our fingertips. After all, in the not-too-distant past, Mars was largely mysterious. All we had were ground-based images of the planet. Now? Now we have daily weather reports and images of dust storms.

On June 25th, 2019, The Planetary Society‘s
Since reaching orbit, the LightSail 2 has been indicated that it is in good working order, as indicated by the Mission Control Dashboard recently introduced by The Planetary Society. In addition to establishing two-way communications with mission controllers and passing a battery of checkouts, the spacecraft also took its first pictures of Earth (and some selfies for good measure).

Saturn opposition season never disappoints. Slowly, one by one, the planets are returning to the dusk sky. In June, we had Jupiter reach opposition on June 10th. Now, although Mercury and Mars are fleeing the evening scene low to the west at dusk and Venus lingers low in the dawn, magnificent Saturn reaches opposition tonight on July 9th, rising to the east as the Sun sets to the west.

On December 11th, 2017, President Trump issued Space Policy Directive-1, a change in national space policy which tasked NASA with the creation of an innovative and sustainable program of exploration that would send astronauts back to the Moon. This was followed on March 26th, 2019, with President Trump directing NASA to land the first astronauts since the Apollo era on the lunar South Pole by 2024.
Named Project Artemis, after twin sister of Apollo and goddess of the Moon in Greek mythology, this project has expedited efforts to get NASA back to the Moon. However, with so much focus dedicated to getting back to the Moon, there are concerns that other projects being neglected – like the development of the Lunar Orbital Platform-Gateway, a central part of creating a sustained human presence on the Moon and going on to Mars.

The ESA is helping a group of students from Zurich test and develop their hopping exploration robot. Called SpaceBok, the robot is designed to operate on low-gravity bodies like the Moon or asteroids. It’s based on the concept of ‘dynamic walking’, something that animals on Earth use.

Titan is a distant, exotic, and dangerous world. It’s frigid temperatures and hydrocarbon chemistry is like nothing else in the Solar System. Now that NASA is heading there, some researchers are getting a jump on the mission by recreating Titan’s chemistry in jars.

Fraser and John Michael Godier Debate the Fermi Paradox
As many of you are no doubt aware, our noble publisher, Fraser Cain, occasionally has the opportunity to sit down with some fellow great minds and discussion/debate issues that are relevant to space, exploration, and astronomy today. Most recently, this included an extended debate with noted author, futurists and Youtube sensation John Michael Godier.
The subject of this debate was the unresolved mystery that keeps more than a few astrophysicists awake at night. This is none other than the Fermi Paradox, the question that asks “Where are they?”
