The contrast was jarring. In one browser window, two NASA astronauts were making their way to the International Space Station (ISS) after the first orbital launch of a crew from U.S. soil in nearly 9 years.
In another window, scenes of chaos played out as protests over the death of George Floyd after his arrest by Minneapolis police erupted into violent clashes across the country.
WASHINGTON (NASA PR) — A NASA-published volume traces the history of human lunar lander concepts developed since Apollo’s Lunar Module (LM). After LM – NASA Lunar Lander Concepts Beyond Apollo tells the story of physics, technology, and the desire to return humans to the lunar surface through technical descriptions, imagery and subsystem mass breakouts of more than 100 lunar lander concepts created by NASA and its contractors since the Apollo program.
The concepts are grouped by the human exploration timelines that defined the post-Apollo period, starting post-Apollo and continuing through the Space Exploration Initiative and the Vision for Space Exploration, and concluding with the many lander designs created to support NASA’s Constellation program. Readers will see the common “trades” that are explored in crewed landing systems, including propellant types, pressurized volumes, structural mass fractions, mass margins, crew size, and special accommodations for ergonomics and other human factors.
Author John Connolly has spent 33 years at NASA, primarily leading development of lunar surface systems, including landers. “I think this compilation illustrates how, when a crewed lunar lander is stripped down to its most basic functions, its form ultimately responds to fundamental physics and human factors,” Connolly said. “With a nod to science fiction, of course.”
GREENBELT, Md. (NASA PR) — NASA hasn’t measured moonquakes since Apollo astronauts deployed a handful of measuring stations at various locations on the lunar surface and discovered unexpectedly that Earth’s only natural satellite was far from seismically inactive.
WASHINGTON, May 1, 2020 (House Science Committee PR) — Yesterday, the National Aeronautics and Space Administration (NASA) announced that Blue Origin, Dynetics, and SpaceX have been awarded contracts to design and develop Artemis program human landing systems, one of which NASA plans to use for a 2024 lunar landing.
“I am troubled that NASA has decided to ignore congressional intent and instead press forward with Human Landing System awards to try to meet an arbitrary 2024 lunar landing deadline,” said Chairwoman Eddie Bernice Johnson (D-TX). “As the Apollo program showed us, getting to the Moon and back safely is hard. The multi-year delays and difficulties experienced by the companies of NASA’s taxpayer-funded Commercial Crew program—a program with the far less ambitious goal of just getting NASA astronauts back to low Earth orbit—make clear to me that we should not be trying to privatize America’s Moon-Mars program, especially when at the end of the day American taxpayers—not the private companies—are going to wind up paying the lion’s share of the costs. I want our Nation to pursue the inspiring goals of returning to the Moon and then heading to Mars, but we need to do it sensibly and safely while we also protect the interests of the tax paying public.”
“America’s human space exploration program has inspired generations and led to discovery, development, and innovation,” said Chairwoman of the Subcommittee on Space and Aeronautics, Rep. Kendra Horn (D-OK). “Returning humans to the Moon safely is an important and worthy endeavor for our nation. It is also a challenging one that requires significant investment of taxpayer dollars to achieve. I was disappointed to see that NASA’s decision on lunar landing systems development starkly contrasts the bipartisan House NASA Authorization bill and the advice of experts on minimizing risk and ensuring the highest likelihood of success in landing humans on the Moon.”
“Unfortunately, more than a year after their announcement to accelerate the Artemis program, NASA has yet to provide Congress a transparent architecture and technical and cost assessment, despite our repeated requests. The American taxpayer deserves to know their money is being spent wisely, especially if they are being asked to invest billions of taxpayer dollars in a private lunar landing system. Our nation should dream boldly and pursue aspirational goals but we have to do so thoughtfully and intentionally. I look forward to working with NASA in good faith to steer our nation’s space program in a direction that allows our country to achieve inspiring goals and explore space in a responsible and measured way.”
HOUSTON (ESA PR) — Almost 50 years after the Apollo missions returned lunar material to Earth, ESA experts are helping to uncover the secrets of two previously unopened samples to learn more about ancient processes on the Moon – and to refine and practice techniques for future sample return missions.
With one sample already being analysed, preparations are now being made to open the second later this year.
MOFFETT FIELD, Calif. (NASA PR) — Moon dust is a formidable adversary – the grains are as fine as powder and as sharp as tiny shards of glass. During the Apollo 17 mission to the Moon, the astronauts lamented how the dust found its way into everything, coating their spacesuits and jamming the shoulder joints, getting inside their lunar habitat and even causing symptoms of a temporary “lunar dust hay fever” in astronaut Harrison Schmitt. Those symptoms fortunately went away quickly – but the problem of Moon dust remains for future missions.
WASHINGTON (NASA PR) — As NASA marks the 50th anniversary of the Apollo 13 mission – which has become known as “a successful failure” that saw the safe return of its crew in spite of a catastrophic explosion – the agency is sharing a variety of resources, recognizing the triumph of the mission control team and the astronauts, and looking at how those lessons learned can be applied to its lunar Artemis program.
WASHINGTON (NASA PR) — Former astronaut Alfred M. Worden, command module pilot on the Apollo 15 lunar landing, passed away March 18, 2020, in Texas.
“I’m deeply saddened to hear that Apollo astronaut Al Worden has passed away,” NASA Administrator Jim Bridenstine tweeted about Worden. “Al was an American hero whose achievements in space and on Earth will never be forgotten. My prayers are with his family and friends.”
The latest audit of NASA’s troubled Space Launch System (SLS) finds the program is now even more behind schedule and over budget than previously thought, with the space agency failing to fully account to Congress for almost $6 billion in program costs.
After spending a few years in hibernation, the Next-generation Suborbital Researchers Conference (NSRC) is being held in Colorado this week. I wasn’t able to attend this year, but I’ve been following all the action on Twitter.
In a keynote address on Monday, NASA Administrator Jim Bridenstine floated the idea of letting the space agency’s astronauts fly aboard Blue Origin’s New Shepard and Virgin Galactic’s SpaceShipTwo suborbital vehicles. He also discussed certifying the systems to comply with a subset of NASA’s human ratings requirements.
New Generations, Equipped with New Technologies, Prepare to Analyze 50-Year-Old Samples in the New Year

GREENBELT, Md. — Fortunately for today’s scientists, Apollo-era leaders had the foresight to save much of the 842 pounds (382 kilograms) of Moon soil and rocks retrieved by NASA astronauts 50 years ago for future generations. They figured new crops of scientists, using instruments of their time, would be able to probe the samples with unprecedented rigor.
Now, the future that Apollo-era scientists envisioned has come. Their successors, many of whom weren’t even born when the last astronauts scooped up the Moon samples they’ll now be probing in their labs, are ready to take a giant leap towards answering long-standing questions about the evolution of our solar system.
NOORDWIJK, Netherlands (ESA PR) — Having spent much of the 21st century developing planetary defence techniques, Apollo astronaut Rusty Schweickart is a strong supporter of ESA’s proposed Hera mission. In general, when it comes to asteroid deflection, he says, two spacecraft are better than one.
HOUSTON (NASA PR) — NASA scientists opened an untouched rock and soil sample from the Moon returned to Earth on Apollo 17, marking the first time in more than 40 years a pristine sample of rock and regolith from the Apollo era has been opened. It sets the stage for scientists to practice techniques to study future samples collected on Artemis missions.
