NASA Accomplishments in 2024

Posted on by onespaceman2000

NASA has plenty of good news to share from 2024, as highlighted in its NASA: Best of 2024 video and accompanying press release.

Just a few of these accomplishments include:

  • In February, the first Moon landing through the agency’s Commercial Lunar Payload Services initiative brought NASA science to the lunar surface on Intuitive Machines’ Nova-C lander successfully capturing data that will help us better understand the Moon’s environment and improve landing precision and safety.
  • After launching into space in February, NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite mission is successfully transmitting first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
  • In June, NASA astronauts Butch Wilmore and Suni Williams safely arrived at the space station aboard Boeing’s Starliner spacecraft following launch of their flight test. With Starliner’s arrival, it was the first time in station history three different spacecraft that carried crew to station were docked at the same time. Starliner returned uncrewed in September following a decision by NASA. Wilmore and Williams, now serving as part of the agency’s Crew-9 mission, will return to Earth in February 2025.
  • Deployed NASA’s Advanced Composite Solar Sail System in space, marking a successful test of its composite boom technology.
  • Awarded nearly $45 million to 21 higher-education institutions to help build capacity for research, and announced the recipients of grants that will support scientific and technical research projects for more than 20 universities and organizations across the United States.

The long list from which this was taken is impressive. However, we also need to note a few of the problems this year. This includes troubled commercial missions to the Moon, a Boeing crew stranded on the International Space Station after a problematic Starliner test, delays in the SpaceX Starship rocket tests, a cancelled Moon rover, budget cuts at NASA as well as layoffs at JPL, cost overruns on the Mars Sample Return mission, and a delay in the Artemis II and III launch dates.

This does not override the accomplishments, but it puts them into context at a time of changing administrations in Washington. This will come with hard questions about the viability of current missions as well as the cost of future missions.

I agree 2024 has plenty of proud moments. That said, 2025 will be a very challenging year for NASA. The agency will need solid answers to hard questions, cost effective options for struggling missions, and plenty of public support to weather calls for additional budget cuts.

I have confidence NASA will come out of this even stronger, even if it is a bit bruised in the process.

Space Quote: The End of Ingenuity on Mars

“When running an accident investigation from 100 million miles away, you don’t have any black boxes or eyewitnesses…While multiple scenarios are viable with the available data, we have one we believe is most likely: Lack of surface texture gave the navigation system too little information to work with.”

-Statement by Ingenuity’s first pilot, Håvard Grip of JPL, in a Jet Propulsion Laboratory (JPL) publication explaining the final flight of the Ingenuity Mars Helicopter on Jan. 18, 2024. The helicopter flew 72 times over the Martian surface, far surpassing NASA’s expectations.

Another Employee Cut at JPL

Posted on by onespaceman2000

Earlier today, NASA’s Jet Propulsion Laboratory (JPL) announced additional employee cuts:

While we have taken various measures to meet our current FY’25 budget allocation, we have reached the difficult decision to reduce the JPL workforce through layoffs. This reduction affects approximately 325 of our colleagues, an impact of about 5% of our workforce. The impacts are occurring across technical, business, and support areas of the Laboratory. These are painful but necessary adjustments that will enable us to adhere to our budget while continuing our important work for NASA and our nation.

You may recall that JPL laid off about 8 percent of its staff back in February due to budget issues associated with the Mars Sample Return, so this is the second hit this year.

Addressing these earlier cuts, Rep. Mike Garcia (R-CA) stated his concerns:

I worry that, when we make certain decisions, that we’re cutting to the bone and, in this case, potentially amputating JPL.

It appears the bone cutting continues, though JPL management stated, “…we will be well positioned for the work ahead.”

Let’s hope so.

We Have Moved from Exoplanet to Exomoon

The search for new exoplanets in our galaxy continues, but now it may include the first exomoon. This was something that was expected to occur at some point as the detection methods became better over time.

The exomoon in question is believed to be a volcanic moon orbiting a giant planet about 635 light-years away. Detected using the European Southern Observatory’s Very Large Telescope in Chile, the exomoon is discussed in a paper written by researchers with NASA’s Jet Propulsion Laboratory and Caltech in California. The clue was a cloud of sodium that did not appear to come from the host exoplanet.

The new discovery is being compared to Jupiter’s volcanic moon Io, which is the most volcanically active world in the solar system.

If you want to learn more about exomoons, I recommend a Cool Worlds video narrated by Assistant Professor of Astronomy David Kipping who provides five reasons that the study of exomoons is so important.

Space Stories: Oxygen Issues on Europa, the Puzzling Expansion Rate of the Universe, and Mini Moon-Bound Rovers

Here are some recent stories of interest.

—The Columbian: “Europa Might Have Less Oxygen Than Expected“

New research suggests there’s less oxygen on the icy surface of Jupiter’s moon Europa than thought — and that could affect what, if any, life might be lurking in the moon’s underground ocean. Even with little or no oxygen, microbes might still be bustling around in the ocean believed to exist miles beneath Europa’s frozen crust. As for what else, “who knows,” said NASA scientist Kevin Hand, who was not involved in the study published Monday in Nature Astronomy.

—Webbtelescope.org: “NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists“

The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. These observations were made by the Planck satellite mapping of the cosmic microwave background radiation – sort of a blueprint for how the universe would evolve structure after it cooled down from the big bang. The simple solution to the dilemma is to say that maybe Hubble observations are wrong due to some creeping inaccuracy in its deep-space yardstick. Then along came the James Webb Space Telescope to crosscheck Hubble’s results. Webb’s sharp infrared views of Cepheids agreed with Hubble data. Webb confirmed that the Hubble telescope’s keen eye was right all along.

—NASA JPL: “NASA’s Network of Small Moon-Bound Rovers Is Ready to Roll“

A trio of small rovers that will explore the Moon in sync with one another are rolling toward launch. Engineers at NASA’s Jet Propulsion Laboratory in Southern California recently finished assembling the robots, then subjected them to a punishing series of tests to ensure they’ll survive their jarring rocket ride into space and their travels in the unforgiving lunar environment. Part of a technology demonstration called CADRE (Cooperative Autonomous Distributed Robotic Exploration), each solar-powered rover is about the size of a carry-on suitcase.
