Move Over Artemis Accords! Behold the Lunar Governance Report and EAGLE Manifesto!

In July 1999, the Space Generation Advisory Council (SGAC) was created with the purpose of representing the “Space Generation” to the UN Office of Outer Space Affairs (UNOOSA). For this non-governmental organization and professional network, this would consist of bringing the “views of students and young space professionals to the United Nations (UN), space industry and other organizations”.

Given the importance of the Moon for all of our future space exploration goals, SGAC created an interdisciplinary group in June of 2020 that is focused on lunar policy. Known as the Effective and Adaptive Governance for a Lunar Ecosystem (E.A.G.L.E.), this group of 14 young space professionals is dedicated to ensuring that the younger generation has a voice when it comes to the development of regulations for lunar policy.

On May 12^th, 2021, the SGAC released the report prepared by the EAGLE group, which outlines their ideas and proposals for how we can ensure that the regulations governing lunar activities are inclusive, effective, and adaptative. It’s known as the Lunar Governance Report, a document that will be presented during the 2021 meetings of the UN Committee on the Peaceful Uses of Outer Space (COPUOS).

The Elements for Life Depend on Both how and Where a Planet Forms

In the past few decades, the number of planets discovered beyond our Solar System has grown into the thousands. At present, 4,389 exoplanets have been confirmed in 3,260 systems, with another 5,941 candidates awaiting confirmation. Thanks to numerous follow-up observations and studies, scientists have learned a great deal about the types of planets that exist in our Universe, how planets form, and how they evolve.

A key consideration in all of this is how planets become (and remain) habitable over time. In general, astrobiologists have operated under the assumption that habitability comes down to where a planet orbits within a system – within its parent star’s habitable zone (HZ). However, new research by a team from Rice University, indicates that where a planet forms in its respective star system could be just as important.

Amazing Views of Wednesday Morning’s Total Lunar Eclipse

The Moon turned a ruddy hue during this morning’s total lunar eclipse, in one of the top astronomical events of the year.

What a celestial show. Depending on your time zone, you either got up early, stayed up late, or pulled an all-niter last night, all in hopes of catching today’s total lunar eclipse. This event favored the Pacific region, with western North American observers catching the eclipse at sunrise/moonset, and Australia, new Zealand and eastern Asia seeing totality transpiring at moonrise/sunset.

Astronauts Could Dust off Themselves and Equipment on the Moon With an Electron Beam

In the coming years, NASA will be sending astronauts to the Moon for the first time since the Apollo Era. This time, and as part of the Artemis Program, NASA also plans to build the necessary infrastructure to establish a sustained human presence on the Moon and eventually missions to Mars – including the Artemis Base Camp and the orbiting Lunar Gateway.

They’ll be getting some new equipment, such as the exploration Extravehicular Mobility Unity (xEMU) spacesuit and a fancy new lunar lander. Of course, as the Artemis astronauts will also have to deal with the same hazards as their predecessors – not the least of which is lunar dust (or regolith). Luckily, NASA is investigating a possible solution in the form of a handheld electron/ultraviolet (UV) device that could mitigate this hazard.

‘Super-Blood Moon’ Total Lunar Eclipse Set For May 26th

The first total lunar eclipse of 2021 occurs early next week and features the largest Full Moon of the year.

Ready for the lunar eclipse drought to come to an end? It’s been a while since we’ve watched the Moon pass through the Earth’s dark inner shadow, to be sure. 2020 featured four lunar eclipses… all of which were faint penumbrals. In fact, you have to go all the waaaaay back to January 21^st, 2019 (remember 2019?) to remember the last total lunar eclipse. But that wait ends next Wednesday morning on May 26^th, with a very short total lunar eclipse, centered on the Pacific region.

A Solution to Space Junk: Satellites Made of Mushrooms?

According to the latest numbers from the ESA’s Space Debris Office (SDO), there are roughly 6,900 artificial satellites in orbit. The situation is going to become exponentially crowded in the coming years, thanks to the many telecommunications, internet, and small satellites that are expected to be launched. This creates all kinds of worries for collision risks and space debris, not to mention environmental concerns.

For this reason, engineers, designers, and satellite manufacturers are looking for ways to redesign their satellites. Enter Max Justice, a cybersecurity expert, former Marine, and “Cyber Farmer” who spent many years working in the space industry. Currently, he is working towards a new type of satellite that is made out of mycelium fibers. This tough, heat-resistant, and environmentally friendly material could trigger a revolution in the booming satellite industry.

60 Years Later, is it Time to Update the Drake Equation?

On November 1^st, 1961, a number of prominent scientists converged on the National Radio Astronomy Observatory in Green Bank, West Virginia, for a three-day conference. A year earlier, this facility had been the site of the first modern SETI experiment (Project Ozma), where famed astronomers Frank Drake and Carl Sagan used the Green Bank telescope (aka. “Big Ear”) to monitor two nearby Sun-like stars – Epsilon Eridani and Tau Ceti.

While unsuccessful, Ozma became a focal point for scientists who were interested in this burgeoning field known as the Search for Extraterrestrial Intelligence (SETI). As a result, Drake and Sagan were motivated to hold the very first SETI conference, wherein the subject of looking for possible extraterrestrial radio signals would be discussed. In preparation for the meeting, Drake prepared the following heuristic equation:

N = R^ x f_p x n_e x f_l x f_i x f_c x L*

This would come to be known as the “Drake Equation,” which is considered by many to be one of the most renowned equations in the history of science. On the sixtieth anniversary of its creation, John Gertz – a film producer, amateur astronomer, board-member with BreakThrough Listen, and the three-term former chairman of the board for the SETI Institute – argues in a recent paper that a factor by factor reconsideration is in order.

In 1.3 Million Years, a Star Will Come Within 24 Light-Days of the Sun

Within the Milky Way, there are an estimated 200 to 400 billion stars, all of which orbit around the center of our galaxy in a coordinated cosmic dance. As they orbit, stars in the galactic disk (where our Sun is located) periodically shuffle about and get closer to one another. At times, this can have a drastic effect on the star that experience a close encounter, disrupting their systems and causing planets to be ejected.

Knowing when stars will make a close encounter with our Solar System, and how it might shake-up objects within it, is therefore a concern to astronomers. Using data collected by the Gaia Observatory, two researchers with the Russian Academy of Sciences (RAS) determined that a handful of stars will be making close passes by our Solar System in the future, one of which will stray pretty close!

Following the Moon for Amazing May Astronomy

The May Moon Meets Venus and Mercury, at dusk en route to eclipse season and more.

Wonder where all the solar system action is hiding? While the dusk sky may seem devoid of planets (save for Mars), that’s all about to change this evening. The watch-phrase for astronomy in May 2021 is to ‘follow the Moon’ as it makes several spectacular planetary passes, then kicks off the first eclipse season of the year.

Blue Origin Will Finally Fly Passengers to the Edge of Space in July

Things have been heating up lately over at Blue Origin, the commercial spaceflight company launched by Amazon founder Jeff Bezos. Since Bezos stepped down as CEO of Amazon to take a more hands-on role with his other projects, the company has made some rather positive strides. This includes a “dress rehearsal” test flight that took place on April 14^th and brought their New Shepard a step closer to bringing passengers to space.

Following the success of this flight, Blue Origin recently announced they are planning to conduct the first crewed flight with the New Shepard by July 20th. In addition to the Blue Origin astronaut crew, one seat is being set aside for a commercial passenger. As of May 5^th, Blue Origin announced that this ticket will be available for auction and that the proceeds will be donated to Blue Origin’s foundation, Club for the Future.
