You may enjoy this week’s episode from the Cool Worlds Podcast all about leaving evidence of our civilization for alien visitors, or even a future civilization here on Earth. The episode, “Nick Searra – Alien Communication, Golden Record, Future Relics,” covers a lot of ground from the Pioneer and Voyager missions to the idea of placing time capsules about our civilization on the Moon or even within the orbit of Jupiter.

The guest is Nick Searra, who is Founder and Executive Directory of the Interstellar Foundation. The Interstellar Foundation has a clear mission – to create messages that represent the diversity and creativity of humanity, inspire future generations of explorers, and communicate with potential extraterrestrial life.

On the site, you an read about the Foundation’s Aspire One, which was an effort to create a lunar record to preserve Earth’s cultural and scientific heritage on the Moon. Preserved records include UNESCO archives, World Heritage images, and other scientific, historical, and cultural material. This message is already on its way to the Moon via this week’s launch of the Blue Ghost lunar lander.

A second messaging mission, Aspire Two, is now in development.

The podcast discussion and related website basically cover the continuation of work stared by Carl Sagan with the launch of Pioneer 10 back in 1972. I recommend you check out both of them.

Blue Origin Looses a Booster, and SpaceX Looses a Rocket

Overall, it was a good week in space with two lunar missions launched and the successful test of Blue Origin’s New Glenn rocket. Unfortunately, it did not end so well when SpaceX lost its Starship rocket during its seventh test of that system.

While the Starship’s booster made another dramatic landing, the rocket itself disintegrated 10 minutes after launch from Texas to became fireworks over the Caribbean. SpaceX prefers the term “rapid unscheduled disassembly,” but the results are the same.

Following the launch, SpaceX posted:

It served as a reminder that development testing, by definition, can be unpredictable…We will conduct a thorough investigation, in coordination with the FAA, and implement corrective actions to make improvements on future Starship flight tests.

It is also worth remembering that fancy booster landings are beside the point when your crew and cargo have disintegrated, which fortunately was not the case here. SpaceX needs to keep its focus on the rocket first and foremost.

Maybe the same can be said about the company’s CEO.

Pic of the Week: Successful Launch of the New Glenn Rocket

Earlier today, Blue Origin’s New Glenn rocket safely made its way into the Earth’s orbit from its launch pad at the Cape Canaveral Space Force Station in Florida. The only piece of the mission that fell short was the loss of the booster that should have landed on a barge in the Atlantic Ocean.

After the successful launch, Blue Origin’s CEO Dave Limp stated:

I’m incredibly proud New Glenn achieved orbit on its first attempt…We knew landing our booster, So You’re Telling Me There’s a Chance, on the first try was an ambitious goal. We’ll learn a lot from today and try again at our next launch this spring. Thank you to all of Team Blue for this incredible milestone.

Even with the lost booster, the rocket launch has proven that the US space industry may soon have another reliable competitor to challenge SpaceX, which is good new for everyone.

Blue Ghost Lunar Lander on its Way to the Moon

Earlier today, a SpaceX rocket successfully launched Firefly Aerospace’s Blue Ghost mission. If it makes it to the lunar surface, it will be the second US mission to land on the Moon since the end of the Apollo program in the 1970s.

Firefly Aerospace issued a press release noting its the initial success of the mission:

Firefly’s Blue Ghost lunar lander launched on a SpaceX Falcon 9 rocket, successfully acquired signal, and completed on-orbit commissioning. With a target landing date of March 2, 2025, Firefly’s 60-day mission is now underway, including approximately 45 days on-orbit and 14 days of lunar surface operations with 10 instruments as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

Blue Ghost Mission 1, named Ghost Riders in the Sky, launched from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, at 1:11 a.m. EST on January 15, 2025. Blue Ghost separated from the SpaceX Falcon 9 rocket in a highly elliptical Earth orbit at 2:17 a.m. EST and established communications with Firefly’s Mission Operations Center in Cedar Park, Texas, at 2:26 a.m. EST. On-orbit spacecraft commissioning was then completed by 5:30 a.m. EST, which included verifying attitude determination and control capabilities, increasing the data transfer rate, establishing a power-positive attitude, and completing initial lander health checks.

This is a big step for Firefly Aerospace, which hopes to build on the success of this mission to launch other lunar missions in the next few years. But we need to take it one step at a time given the two US commercial lunar missions that failed earlier last year.

Note: The SpaceX launch also included a Japaneses private sector Moon mission – iSpace’s HAKUTO-R M2 “Resilience” lunar lander. This is the second Moon mission for iSpace. The first mission crashed into the Moon’s surface back in 2023.

iSpace has shown resilience after the previous attempt. A successful mission will be a good sign for the company and the private lunar industry as well.

Space Stories: The Disappearance of Dark Skies in Chile, Subaru Telescope Gets New Eye, and Roman Telescope Previews

Here are some recent stories related to astronomy telescopes.

—Sky & Telescope: “Industrial Project Threatens Dark Chilean Skies“

When a study in 2023 crowned Cerro Paranal the darkest observatory site in the world, astronomers must have felt reassured to have chosen the right spot. The 2,635-meter (8,645-foot) mountain in Chile’s Atacama Desert is home to the European Southern Observatory’s (ESO) Very Large Telescope, one of the most advanced and prolific astronomical facilities. But now, if a company named AES Andes (a subsidiary of the U.S. power company AES Corporation) gets its way, Paranal’s observational prowess might soon be history: Light pollution emitted by a proposed industrial “megaproject” could do away with the dark skies over this observatory.

—National Astronomical Observatory of Japan: “Prime Focus Spectrograph on the Subaru Telescope to Begin Science Operations in February“

Researchers have finished equipping the Subaru Telescope with a new special “compound eye,” culminating several years of effort. This new eye is an instrument featuring approximately 2,400 prisms scattered across the extremely wide field of view available at the Subaru Telescope’s primary focus, allowing for simultaneous spectroscopic observation of thousands of celestial objects. This unrivaled capability will help researchers precisely understand the formation and evolution of galaxies and the Universe. Among 8-meter-class telescopes, the Subaru Telescope is the most competitive with the largest survey capability in the world. This instrument, the Prime Focus Spectrograph (PFS), will be ready to begin scientific operations in February 2025.

—NASA: “Simulated Universe Previews Panoramas from NASA’s Roman Telescope“

Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore Roman’s myriad science goals. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing every photon’s path all the way from each cosmic object to Roman’s detectors,” said Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, who led the simulation campaign. “This is the largest, deepest, most realistic synthetic survey of a mock universe available today.”
