The Moon Landing: Imperfect, but Accomplished

The United States is back on the Moon, even if the trip was bumpy. Plans to have pictures of the landing via the EagleCam were affected by a last minute switch to a NASA instrument that allowed Odysseus to safely land. The seems to be a fair trade, and the EagleCam can still be used to take pictures now that the lunar lander is stationary on the surface.

Embry‑Riddle Aeronautical University, which created the EagleCam, later noted:

…both the Intuitive Machines and EagleCam teams still plan to deploy EagleCam and capture images of the lander on the lunar surface as the mission continues. The time of deployment is currently unknown.

More importantly, Odysseus stumbled during the landing and is now tipped to one side. A tilted landing disabled the Japanese lunar lander earlier this year. Fortunately, the Odysseus’s solar panels are still catching the Sun’s rays and charging. This should allow the lander to conduct its work for about nine days until the Sun’s location will no longer charge the panels.

It seems the third try this year for the Moon’s south pole was precarious yet ultimately successful. That said, we are finding that the past successes are no guarantee of future success. This is the same region where NASA will be sending the Artemis astronauts. We need to get this right before we drop a crew on the Moon.

All Eyes on the Next Moon Mission

The second NASA-related commercial Moon mission was set to launch earlier today, but SpaceX called it off at the last moment due to a methane issue with its Falcon 9 rocket. SpaceX is expected to try the launch tomorrow.

The launch of the Intuitive Machines IM-1 mission is related to NASA’s Commercial Lunar Payload Services (CLPS) initiative, and will serve as one of the first lunar-based pieces of the Artemis program.

In terms of the main mission, NASA noted:

Intuitive Machines’ Nova-C lander is expected to land on the Moon Thursday, Feb. 22. Among the items on its lander, the IM-1 mission will carry NASA science and technology instruments focusing on plume-surface interactions, space weather/lunar surface interactions, radio astronomy, precision landing technologies, and a communication and navigation node for future autonomous navigation technologies.

The Moon mission that failed last month was also part of NASA’s CLPS initiative. This program is off to a slow start, but hopefully it can be relied on to be a key component of the lunar space program going forward.

If you are looking for some good news, I can report that Russia’s Progress MS-26 International Space Station resupply mission successfully launched earlier today.

Space Quote: NASA Cannot Do Everything in this Budget Environment

Posted on by onespaceman2000
 

“The current budget environment has significant implications for mission and safety risk. NASA has a very full mission plate. To the extent that their budget request is not fully funded, the leadership will need to acknowledge and make critical decisions with respect to program content or schedules, which will need to be adjusted to meet fiscal realities. Attempting to do all planned efforts on expected timelines will introduce unacceptable and unmanaged risk. The Agency will need to rely on its developed strategic vision, objectives, and architecture to establish well-defined priorities to ground its endeavors in reality – taking fully into account the risk-benefit tradeoffs.”

-Statement in the Aerospace Safety Advisory Panel’s 2023 Annual Report regarding NASA’s operating environment. One particular area of risk relates to Artemis III, which entails a crewed landing on the Moon. The report states:

In addition, prior to the Artemis III mission, NASA will need to address whatever issues arise from the Artemis II mission, including the possibilities of hardware (HW) and software (SW) changes to both the Space Launch System (SLS) and Orion. Orion flight time on Artemis III will exceed previous durations. Given that it is a new rocket, a new human capsule, and a new human spaceflight environment for this generation of NASA workers, it is not unreasonable to think that NASA will still have a great deal of discovery to do with every Artemis mission for the foreseeable future, and that both schedules and workloads will need to expand accordingly.

Space Stories: The ISS Succession Plan, Privately-built Moon Landers, and Working with Moonquakes

Here are some recent stories of interest.

—Aviation Week Network: “Safety Panel Raises Commercial Space Station Transition Concerns“

Concerns over a “very tight” timeline for NASA to transition human low-Earth-orbit operations from the International Space Station (ISS) to commercial successors tops a list of seven concerns raised by an agency safety panel. The latest annual report by NASA’s Aerospace Safety Advisory Panel’s (ASAP) was released Jan. 25. The 56-page report expresses concerns over sufficient evidence of a viable business case to make NASA one of multiple tenants of at least one ISS successor. The effort is currently supported by NASA and the European, Japanese, Russian and Canadian space agencies.

—Astronomy.com: “Vertex Moon Mission Getting Closer to Launch“

 A new era in lunar research is coming, and Lunar Vertex is getting ready to lead the way. Lunar Vertex is NASA’s first so-called PRISM mission (Payloads and Research Investigations on the Surface of the Moon). PRISM taps into the Commercial Lunar Payload Services program that uses privately built landers to deliver NASA science and other payloads to the lunar surface. PRISM missions are meant to be lower-cost, faster-to-flight programs. There is a mass limit of just over 100 pounds (45 kilograms) — so the science instruments have to be small — and the budget for the first PRISM suite is just $30 million (excluding the lander and the launch vehicle). Lunar Vertex is first in line, and recently has hit a number of major milestones on its way to a June 2024 launch.

—NASA: “Shrinking Moon Causing Moonquakes and Faults Near Lunar South Pole“

As NASA continues to make progress toward sending astronauts to the lunar South Pole region with its Artemis campaign, data from a NASA-funded study is helping scientists better understand this strategic part of the Moon. The study presents evidence that moonquakes and faults generated as the Moon’s interior gradually cools and shrinks are also found near and within some of the areas the agency identified as candidate landing regions for Artemis III, the first Artemis mission planned to have a crewed lunar landing.

Will China Beat Us to the Moon?

With the newly announced delays related to the Artemis lunar program, it is fair to ask whether the U.S. might fall behind the Chinese when it comes to a crewed lunar mission (of course, we won that battle 50 years ago, but you know that I mean).

All reports indicate that the Chinese wants to place humans on the Moon by 2030, but they are not expected to beat the Artemis timetable of a lunar landing in 2026. Of course, it is important that NASA stick to this timetable.

NASA Administrator Bill Nelson recently stated:

I do not have a concern that China is going to land before us…I think that China has a very aggressive plan. I think they would like to land before us, because that might give them some PR coup. But the fact is that I don’t think they will. I think it is true that their date that they announced keeps getting earlier. But specifically, with us landing in September of ’26, that will be the first landing.

Obstacles remain on what will prove to be a difficult mission even if it is a repeat. We already saw Russia’s failed attempt to simply land on the Moon last year, and the problems with last week’s NASA-funded commercial launch towards the Moon was worrying.

Nothing can be taken for granted in this new space race.
