Super Blue Moons: Your Questions Answered

A trifecta of labels is being applied to the Moon of Aug. 19, 2024. It’s a full moon, a supermoon, and finally a blue moon. You may hear it referred to as a super blue moon as a result. It sounds exciting, but what does that really mean? We’ve got you covered.

What is a supermoon?

The Moon travels around our planet in an elliptical orbit, or an elongated circle, with Earth closer to one side of the ellipse. Each month, the Moon passes through the point closest to Earth (perigee) and the point farthest from Earth (apogee). When the Moon is at or near its closest point to Earth at the same time as it is full, it is called a “supermoon.” During this event, because the full moon is a little bit closer to us than usual, it appears especially large and bright in the sky.

Because the Moon’s orbit wobbles and differs depending on where the Sun and Earth are in their orbits, the exact distance of these closest and furthest points varies. But the Moon can look up to 14 percent bigger at perigee than apogee.

OK, so what is a blue moon?

A monthly blue moon occurs when we see the full moon twice in a single month. The Moon’s cycle is 29.5 days, so just a bit shorter than the average length of a calendar month. Eventually that gap results in a full moon happening at the beginning of a month with enough days still remaining for another full cycle ― so a second full moon in the same month. In other words, a full moon that happens on the 1st or 2nd of a month will probably be followed by a second full moon on the 30th or 31st. This happens every two to three years.

A seasonal blue moon occurs when there are four full moons in a single season (spring, summer, fall and winter) instead of the usual three. The third moon in this lineup is a blue moon. This Aug. 19 moon is a seasonal blue moon.

Will the Moon be blue?

No, that’s just the term for two full moons in a month, or the third full moon in a season with four.

Is the Moon ever blue?

On rare occasions, tiny particles in the air ― typically of smoke or dust ― can scatter away red wavelengths of light, causing the Moon to appear blue.

Will this Moon be bigger and more “super?”

You probably won’t notice a big difference in size. When the Moon is closest to Earth (a “supermoon”), it can look up to 14 percent bigger than when it’s farthest from Earth. This is similar to the size difference between a quarter and a nickel. Because the Moon will be close to us in its orbit, it will appear a bit brighter than usual.

Do blue moons and supermoons always occur together?

No. The term “supermoon” is used to describe a full Moon that occurs within a day or so of perigee, so they happen three to four times a year. About 25 percent of all full moons are supermoons, but only 6 percent of full moons are blue moons (seasonal and monthly). The time between super blue moons is quite irregular ― it can be as much as 20 years ― but in general, 10 years is the average. However, if you like to celebrate both seasonal and monthly blue moons, the gap is closer to five years.

Monthly blue moons always occur in the last two or three days of the month. A monthly blue moon in January is usually followed by another one in March of the same year. And in fact, the next monthly super blue moons will occur as a pair, in January and March 2037. Seasonal blue moons always occur almost exactly one month before an equinox or a solstice. The next seasonal blue moon will be on Aug. 21, 2032.

So if it’s not blue and not super-sized, is this worth checking out?

NextSTEP R: Lunar Logistics and Mobility Studies

Solicitation Number: NNH16ZCQ001K-Appendix-R

August 16, 2024 – Draft Solicitation Released

Solicitation Overview

The National Aeronautics and Space Administration (NASA) intends to release a solicitation under the Next Space Technologies for Exploration Partnerships-2 (Next STEP-2) Broad Agency Announcement (BAA) to seek industry-led concept definition and maturation studies that address lunar surface logistics and uncrewed surface mobility capabilities.

NASA’s Moon to Mars Architecture defines the elements needed for long-term, human-led scientific discovery in deep space. NASA’s architecture approach distills agency-developed objectives into operational capabilities and elements that support science and exploration goals. Working with experts across the agency, industry, academia, and the international community, NASA continuously evolves that blueprint for crewed exploration, setting humanity on a path to the Moon, Mars, and beyond.

NASA has identified two gaps in its lunar architecture: an integrated surface logistics architecture and uncrewed surface mobility systems for lunar surface assets. The objective of these studies is to seek proposals from industry for the conduct of studies specifically focused on the envisioned logistics and mobility capabilities as stated in NASA’s 2024 Architecture Concept Review White Papers (Lunar Surface Cargo, Lunar Mobility Drivers and Needs) and 2023 Architecture Concept Review White Paper (Lunar Logistics Drivers and Needs).

The Exploration Systems Development Mission Directorate (ESDMD) Strategy and Architecture Office (SAO) Lunar Logistics and Mobility Studies BAA (NextSTEP-2 Appendix R) is structured to meet the following goals:

• Identify innovative strategies and concepts for logistics and mobility solutions. This could include a variety of topics, including but not limited to:
  • synergies between logistics- and mobility-specific capabilities.
  • identification of logistics- and mobility-specific needs that may be beyond current and/or planned commercial capabilities.
  • innovative ideas for partnership business models, including intellectual property, asset ownership, and timing of asset delivery, and/or services to the government.
  • the use of advanced robotic and/or autonomous capabilities.

• Evaluate and understand driving technology maturity, cost, and schedule drivers for meeting reference technical requirements, and/or drivers for validating a concept of operations.
• Obtain data that supports NASA’s ability to define, derive, and validate logistics and mobility requirements. Said data could inform a baseline mission concept that identifies options for and approaches to meeting logistics- and mobility-specific capabilities. This data could also contribute to the verification/validation of logistics and mobility approaches that could support NASA’s lunar architecture.

To support lunar surface operations, NASA is seeking state-of-the-art industry studies that provide an approach for technology investigation/maturation and concept development for the following:

• Logistics carriers – Logistics carriers of various sizes, volumes, and configurations and the environmental control of the cargo compartment.
• Logistics Handling and Offloading – Handling and offloading unpressurized cargo, carriers, fluids, and gases.
• Logistics Transfer – The transfer of cargo from the lunar surface to a pressurized volume,
• Staging, Storage and Tracking – Managing surface logistics inventory prior to, during, and after delivery to the final point of use.
• Trash Management – Trash management that contributes to mission sustainability and maximizes crew efficiency,
• Surface Cargo Transportation and Mobility Systems – The movement of cargo containers on the lunar surface after delivery by a lander.
• Integrated Strategy – An approach for an integrated assessment of the lunar surface logistics strategy and the transportation of the logistics to the pressurized habitation elements. This can also include the incorporation of the launch vehicle and cargo lander as part of the transportation.

The resulting studies will ensure advancement of NASA’s development of lunar surface logistics and mobility technologies, capabilities, and concepts.

NASA CubeSats Launch as Commercial Rideshares

A pair of CubeSats from NASA’s Pathfinder Technology Demonstrator, or PTD, series lifted off on SpaceX’s Transporter-11 rideshare mission at 11:56 a.m. PDT Friday, August 16, from Vandenburg Space Force Base in California. The two small satellites, PTD-4 and PTD-R, will help advance NASA’s efforts to validate novel technologies and increase small spacecraft capabilities in order to shape the future of space exploration and technology.

PTD-4 will demonstrate a high-power, low-volume deployable solar array with an integrated antenna, while PTD-R will focus on testing simultaneous ultraviolet and short-wave infrared optical sensing from space for the first time via two 85-mm aperture monolithic telescopes mounted side-by-side. The two CubeSats use a six-unit (6U) spacecraft, named Triumph, common to all PTD satellites.

L2 Solutions DBA SEOPS LLC secured the launch of the two CubeSats for NASA as part of an award on the agency’s VADR (Venture-class Acquisition of Dedicated and Rideshare) contract. This is part of an effort to embrace more commercial practices to achieve lower launch costs, which provide new opportunities for these small but highly capable small satellites to find a ride to space. These highly flexible contracts help broaden access to space through lower launch costs and serve as an ideal platform for contributing to NASA’s science research and technology development.

NASA Awards $1.25 Million to Three Teams at Deep Space Food Finale

NASA has awarded a total of $1.25 million to three U.S. teams in the third and final round of the agency’s Deep Space Food Challenge. The teams delivered novel food production technologies that could provide long-duration human space exploration missions with safe, nutritious, and tasty food.

The competitors’ technologies address NASA’s need for sustainable food systems for long-duration habitation in space, including future Artemis missions and eventual journeys to Mars. Advanced food systems also could benefit life on Earth and inspire food production in parts of the world that are prone to natural disasters, food insecurity, and extreme environments.

“The Deep Space Food Challenge could serve as the framework for providing astronauts with healthy and delicious food using sustainable mechanisms,” said Angela Herblet, challenge manager for the Deep Space Food Challenge at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The challenge has brought together innovative and driven individuals from around the world who are passionate about creating new solutions that support our agency’s future Moon to Mars missions.”

Since the challenge’s launch in 2021, more than 300 teams from 32 countries have participated by submitting innovative food system designs. The competition, conceived and managed by NASA Centennial Challenges at NASA Marshall, is a first-of-its-kind coordinated effort between NASA and CSA (Canadian Space Agency), which ran its own challenge in parallel.

Four American teams competed in Phase 3, which began in September 2023. The Methuselah Foundation partnered with Ohio State University to facilitate the final phase of the challenge, which included a two-month testing and demonstration period held on the university’s campus in Columbus, Ohio. Each U.S. team in Phase 3 was awarded $50,000 and took their technology to Columbus for testing.

Throughout this phase, the teams constructed full-scale food production systems that were required to pass developmental milestones like safety, sensory testing, palatability, and harvesting volumes. Each team worked with four “Simunauts,” a crew of Ohio State students who managed the testing and demonstrations for Phase 3 over the eight-week period. The data gathered from testing was delivered to a judging panel to determine the winner.

The challenge concluded at the Deep Space Food Symposium, a two-day networking and learning summit at the Nationwide and Ohio Farm Bureau 4-H Center on Aug. 15 and 16. Throughout the event, attendees met the Phase 3 finalists, witnessed demonstrations of the food production technologies, and attended panels featuring experts from NASA, government, industry, and academia. The winners of the challenge were announced at an awards ceremony at the end of the symposium.

The U.S. winner and recipient of the $750,000 grand prize is Interstellar Lab of Merritt Island, Florida. Led by Barbara Belvisi, the small business combines several autonomous phytotrons and environment-controlled greenhouses to support a growth system involving a self-sustaining food production mechanism that generates fresh vegetables, microgreens, and insects necessary for micronutrients.

Two runners-up each earned $250,000 for their food systems’ successes: Nolux of Riverside, California, and SATED of Boulder, Colorado.

Nolux, a university team led by Robert Jinkerson, constructed an artificial photosynthetic system that can create plant and fungal-based foods without the operation of biological photosynthesis.

Standing for Safe Appliance, Tidy, Efficient & Delicious, SATED is a one-man team of Jim Sears, who developed a variety of customizable food, from pizza to peach cobbler. The product is fire-safe and was developed by long-shelf-life and in-situ grown ingredients.

NASA also selected and recognized one international team as a Phase 3 winner: Solar Foods of Lappeenranta, Finland, developed a food production system through gas fermentation that relies on single-cell protein production.

In April 2024, CSA and Impact Canada awarded the grand prize winner of its parallel challenge to Ecoation, a Vancouver-based small business specializing in greenhouses. 

“Congratulations to the winners and all the finalist teams for their many years dedicated to innovating solutions for the Deep Space Food Challenge,” said Amy Kaminski, program executive for NASA’s Prizes, Challenges, and Crowdsourcing at NASA Headquarters in Washington. “These food production technologies could change the future of food accessibility on other worlds and our home planet.”

Also present at the symposium was celebrity chef and cookbook author Tyler Florence. After spending time with each finalist team and getting acquainted with their food systems, Florence selected one team to receive the “Tyler Florence Award for Culinary Innovation.” Team SATED of Boulder, Colorado, received the honor for their system that impressed Florence due to its innovative approach to the challenge.

The Deep Space Food Challenge, a NASA Centennial Challenge, is a coordinated effort between NASA and CSA. Subject matter experts at Johnson Space Center in Houston and Kennedy Space Center in Florida, supported the competition. NASA’s Centennial Challenges are part of the Prizes, Challenges, and Crowdsourcing program within NASA’s Space Technology Mission Directorate and managed at Marshall Space Flight Center in Huntsville, Alabama. The Methuselah Foundation, in partnership with NASA, oversees the United States and international competitors.
