Artemis 1 Probably won't Launch Until August

On March 17^th, the Artemis I mission rolled out of the Vehicle Assembly Building (VLB) and was transferred to Launch Complex 39B at the NASA Kennedy Space Center in Florida. This was the first time that a fully-stacked Space Launch System (SLS) and Orion spacecraft were brought to the launchpad in preparation for a “wet dress rehearsal.” To mark the occasion, NASA released a video of the event that featured a new song by Pearl Jam’s Eddie Vedder (“Invincible”).

Unfortunately, technical issues forced ground controllers to scrub the dress rehearsal repeatedly and return the Artemis I to the VLB on April 26^th. This was followed by reports that these issues were addressed and that Artemis I rocket would return to LC 39B by early- to mid-June. Meanwhile, an official NASA statement (issued on Thursday, May 8^th) says that the official launch of the mission is not likely to take place until August at the earliest.

What’s the Best Way to Build Landing Pads on the Moon?

In the near future, NASA, the European Space Agency (ESA), China, and Roscosmos all mount crewed missions to the Moon. This will constitute the first time astronauts have walked on the lunar surface since the Apollo Era. But unlike the “Race to the Moon,” the goal of these programs is not to get their first and leave only a few experiments and landers behind (i.e., “footprints and flags” missions) but to establish a sustained human presence on the lunar surface. This means creating habitats on the surface and in orbit that can be used by rotating crews.

While NASA and other space agencies intend to leverage local resources as much as possible – a process known as In-Situ Resource Utilization (ISRU) – creating lunar bases will still require lots of materials and machinery to be shipped from Earth. In a recent study, Philip Metzger and Greg Autry reviewed the cost and energy consumption of building landing pads on the lunar surface. After considering various construction methods, they determined that a combination of additive manufacturing and polymer infusion was the most efficient and cost-effective means.

Canada's Criminal Laws now Extend to Earth Orbit and the Moon

In this decade and the next, astronauts will be going to space like never before. This will include missions beyond Low Earth Orbit (LEO) for the first time in over fifty years, renewed missions to the Moon, and crewed missions to Mars. Beyond that, new space stations will be deployed to replace the aging International Space Station (ISS), and there are even plans to establish permanent human outposts on the Lunar and Martian surfaces.

In anticipation of humanity’s growing presence in space, and all that it will entail, legal scholars and authorities worldwide are looking to extend Earth’s laws into space. In a recent decision, the Canadian government introduced legislation extending Canada’s criminal code to the Moon. The amendment was part of the Budget Implementation Act (a 443-page document) tabled and passed late last month in Canada’s House of Commons.

Lunar Samples Have Been in the Deep Freeze for 50 Years. NASA Finally has the Right Technology to Study Them Properly

Curators handling lunar rocks take extreme care to keep these materials from contamination as they work with them in cold boxes using gloves and protective gear.

Ever wonder what happened to all those collections of rocks and dust the Apollo astronauts brought back from the Moon? Some of those lunar samples were studied right away. Others made their way into a few museums and science centers and the desks of world leaders. Still others landed in storage at NASA Johnson’s Space Center in Houston. Some got stored at room temperature while others were put into a deep freeze. The idea was to preserve any traces of gases or water or possibly organic materials on them. Now, some of these lunar samples are at the NASA Goddard Space Flight Center in Maryland, where they’re under examination for the first time in 50 years using new techniques not available during the Apollo years.

NASA Announces the Winners of its Second Payload Challenge!

Lunar exploration has advanced considerably in the last two decades, with more countries sending robotic orbiters, landers, and rovers to the surface than ever before. These missions have taught us much about the Moon’s geological evolution, composition, environment, and resources. In a few years, this information will prove vital as NASA sends the first astronauts to the Moon since the Apollo Era (as part of the Artemis Program). They will be followed by many more crewed missions, which will eventually lead to the creation of lunar bases.

Alas, there is still a lot that we still need to know before regular, long-duration missions to the Moon can be conducted. To help fill in the gaps in our knowledge, HeroX launched the “Honey, I Shrunk the NASA Payload, the Sequel” Challenge in September 2020. With up to $800,000 in prizes, this competition sought innovative miniature payload designs that could collect information about the lunar environment and its potential resources. The competition’s winners were announced today during the Lunar Surface Innovation Consortium Spring meeting.

Planetary Decadal Survey Says it’s Time for a Mission to Uranus (and Enceladus too!)

Since 2002, the United States National Research Council (NRC) has released a publication that identifies objectives and makes recommendations for science missions for NASA, the National Science Foundation, and other government agencies for the next decade. These reports, appropriately named Planetary Science Decadal Surveys, help inform future NASA missions that address the mysteries that persist in astronomy, astrophysics, earth science, and heliophysics.

On Thursday, April 19^th, in a briefing in Washington D.C., the National Academies of Sciences, Engineering, and Medicine (NASEM) shared the main findings of the Planetary Science and Astrobiology Decadal Survey 2023-2032. The event was live-streamed and consisted of NASEM committee members discussing the key science questions, priority missions, and research strategies identified and recommended, followed by a Q&A session with the audience.

NASA is Having a Tough Time Testing the SLS

NASA’s Space Launch System (SLS) has been having some problems getting tested since it rolled out onto launch pad 39B last month. These tests, called wet dress rehearsals, are used to find any problems with loading the propellant and verify that all of the rocket’s systems are able to handle it being exposed to cryogenics.

After this most recent attempt on April 14th, it is clear that the SLS isn’t ready for flight yet. The problems that the teams have been encountering have led them to make some procedural changes and slight adjustments in operations and software triggers. There are also the leak problems that have shown up that have to be addressed.

NASA Will be Testing SLS Over the Weekend

The Space Launch System (SLS) has just one more hurdle to clear before this summer’s historic launch. This is known as the Wet Dress Rehearsal, where the fully-stacked SLS and Orion spacecraft will conduct a series of operations at the NASA Kennedy Space Center in Florida. This test follows the arrival of the SLS to Launch Complex 39B after making its big rollout on March 17th from the Vehicle Assembly Building (VLB).

The Wet Dress Rehearsal will run from Friday, April 1st, through Sunday, April 3rd, and will see the Artemis I launch team load propellant into the rocket’s tanks, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and also drain propellants to give them an opportunity to practice the timelines and procedures they will use for launch. The weekend-long event will be live-streamed via the Kennedy Newsroom YouTube channel.

Pearl Jam's Eddie Vedder Provides the Music for NASA's new SLS Video

For fans of Eddie Vedder, Pearl Jam, and space exploration, this video will require very little explanation. But just in case some people haven’t seen it yet, this musical performance was a tribute to the long-awaited roll-out of the fully-stacked Space Launch System (SLS) at the NASA Kennedy Space Center in Florida. It’s guaranteed to give you goosebumps and maybe even bring a tear to your eye!

Under the full Moon, NASA’s Space Launch System (SLS) rocket rolled out to the launchpad for the first time. The journey began at the iconic Vehicle Assembly Building at Kennedy Space Center, with the gigantic stack of the mega rocket arriving at Launch Pad 39B in preparation for a series of final checkouts before its Artemis I test flight.

The four-mile trip for SLS and the Orion spacecraft, on top of the crawler-transporter took 10 hours and 28 minutes, and the 3.5-million-pound rocket and spacecraft arrived at the pad at 4:15 a.m. on March 18.
