Lunar Safe Haven

Posted by

 





 

NASA dicit:

NASA must place more emphasis on protecting both the crew and the exploration surface systems if they hope to achieve long-duration sustainability on the lunar surface. It is now reasonably achievable with excavation, construction, and autonomy technologies to achieve a significant level of protection that architectures have been unable to achieve to date. The Lunar Safe Haven (LSH) was proposed to protect astronauts, electronics, and other surface exploration systems from the hazards of the lunar environment, including radiation, micrometeoroid strikes, lunar dust, thermal vacuum, and more.

NASA dicit:

This year, the Lunar Reconnaissance Orbiter (LRO) celebrates its 13th anniversary orbiting the Moon. This mission has given scientists the largest volume of data ever collected by a planetary science mission at NASA. Considering that success and the continuing functionality of the spacecraft and its instruments, NASA has awarded the mission an extended mission phase to continue operations. This is LRO’s 5th extended science mission (ESM5), and during this time there will be 4 major areas of focus.

Capstone

Posted by

 

 

NASA dicit:

A microwave oven–sized CubeSat weighing just 55 pounds will serve as the first spacecraft to test a unique, elliptical lunar orbit as part of the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE). As a pathfinder for Gateway, a Moon-orbiting outpost that is part of NASA’s Artemis program, CAPSTONE will help reduce risk for future spacecraft by validating innovative navigation technologies and verifying the dynamics of this halo-shaped orbit.

The orbit, formally known as a near rectilinear halo orbit (NRHO), is significantly elongated. Its location at a precise balance point in the gravities of Earth and the Moon, offers stability for long-term missions like Gateway and requires minimal energy to maintain. CAPSTONE’s orbit also establishes a location that is an ideal staging area for missions to the Moon and beyond. The orbit will bring CAPSTONE within 1,000 miles of one lunar pole on its near pass and 43,500 miles from the other pole at its peak every seven days, requiring less propulsion capability for spacecraft flying to and from the Moon’s surface than other circular orbits.

After a three-month journey to its target destination, CAPSTONE will orbit this area around the Moon for at least six months to understand the characteristics of the orbit. Specifically, it will validate the power and propulsion requirements for maintaining its orbit as predicted by NASA’s models, reducing logistical uncertainties. It will also demonstrate the reliability of innovative spacecraft-to-spacecraft navigation solutions as well as communication capabilities with Earth. The NRHO provides the advantage of an unobstructed view of Earth in addition to coverage of the lunar South Pole.

SLS Avionics

Posted by

 

 

Wikipedia dicit:

NASA teams across the country are preparing for the Artemis I launch to the Moon. When NASA’s mighty Space Launch System rocket launches to the Moon from the agency’s Kennedy Space Center in Florida, its four RS-25 engines and two solid rocket boosters will produce more than 8.8 million pounds of thrust. The rocket’s flight software and avionics systems act as the brains behind that muscle to guide and steer the rocket beyond Earth’s orbit.

Michael Collins (1930 – 2021)

Posted by

 

 

Gemini and Apollo astronaut Michael Collins, our beloved father and grandfather, died on
Wednesday, April 28, 2021, after a valiant battle with cancer. He was 90. This day also marked
the 64th wedding anniversary between Mike and his late wife, Patricia Finnegan Collins.

Please join us in fondly and joyfully remembering his sharp wit, his quiet sense of purpose and
his wise perspective, gained both from looking back at Earth from the vantage of space and
gazing across calm waters from the deck of his fishing boat.

As the command module pilot on NASA’s Apollo 11 mission, Mike circled the moon while Neil
Armstrong and Buzz Aldrin touched down at Tranquility Base on July 20, 1969. When his two
crewmates returned from the surface, he was in the unique position to capture a photo of all of
humanity — his fellow astronauts on board the lunar module and everyone else on Earth off in
the distance.

“Today the nation lost a true pioneer and lifelong advocate for exploration in astronaut Michael
Collins,†acting NASA administrator Steve Jurczyk said in a statement. “As pilot of the Apollo
11 command module – some called him ‘the loneliest man in history’ – while his colleagues
walked on the moon for the first time, he helped our nation achieve a defining milestone.â€

Path to the moon

A member of NASA’s third group of astronauts selected in 1963, Mike’s path to joining the first
moon landing began with a three-day flight in Earth orbit. Assigned as the pilot aboard Gemini
10, he launched with John Young in July 1966 on a mission that demonstrated rendezvous and
docking with two rocket stages.

Mike performed two spacewalks on Gemini 10, becoming only the fourth person to exit a
spacecraft to work in the vacuum of space and the first to conduct two on the same mission.
On his second extravehicular activity (EVA), he became the first astronaut to transfer to another
vehicle, retrieving a cosmic dust collector from the exterior of an earlier launched Agena target
stage.

After Gemini 10, Mike was assigned to what was slated to be a test of the complete Apollo
spacecraft in Earth orbit (that flight, Apollo 8, later was changed to be the first mission to send
humans into orbit around the moon). In the course of his training, though, he developed
problems with his legs and ultimately required surgery to correct for a cervical disc herniation.
Given the time needed for his recovery, he was removed from the crew and reassigned to
Apollo 11.

Though he later pondered if Apollo 8 might someday be seen as the more historic mission (“As
you look back 100 years from now, which is more important, the idea that people left their
home planet or the idea that people arrived at their nearby satellite?”), Mike was very happy to
be part of the Apollo 11 crew — even if he was not one of the moonwalkers.

“It’s one of the questions I get asked a million times, ‘God, you got so close to the moon and
you didn’t land. Doesn’t that really bug you?’ It really does not,” he said.

“I honestly felt really privileged to be on Apollo 11, to have one of those three seats. I mean,
there were guys in the astronaut office who would have cut my throat ear to ear to have one of
those three seats. I was very pleased to have one of those three,” he said. “Did I have the best
of the three? No. But was I pleased with the one I had? Yes! And I have no feelings of
frustration or rancor or whatever. I’m very, very happy about the whole thing.”

Having decided before Apollo 11 lifted off that it would be his last mission, Mike splashed
down from the moon having accumulated a total of 11 days, 2 hours and 4 minutes in space
over the course of his two flights.

Around the world

Mike was born on Oct. 30, 1930, in Rome, Italy, where his father, a career U.S. Army officer,
was stationed. After moves from Oklahoma to New York to Maryland to Ohio to Puerto Rico to
Texas to Virginia, he attended St. Albans preparatory school in Washington, D.C. He then
received an appointment to the U.S. Military Academy at West Point, New York, where Mike
earned his Bachelor of Science in 1952.

Enlisting in the Air Force, Mike was trained on and flew F-86 fighter jets out of Nellis Air Force
Base in Nevada and George Air Force Base in California, before being assigned overseas to
the Chambley-Bussières Air Base in France and to West Germany during the 1956 Hungarian
Revolution. He returned to the U.S. the following year, where he attended an aircraft
maintenance officer course and then commanded a mobile training detachment, traveling to air
bases around the world.

In 1960, Mike reported to the Air Force Experimental Flight Test Pilot School (later Aerospace
Research Pilot School) at Edwards Air Force Base in California. He applied for NASA’s second
class of astronauts but was not selected.

Instead, in 1962, he took a postgraduate course on the basics of spaceflight, which included
flying F-104 supersonic jets to 90,000 feet (27,000 m) and training in weightlessness on
parabolic flights. He graduated and returned to fighter operations at Randolph Air Force Base
in Texas when he was accepted with the third group of NASA astronauts.

Prior to flying on Gemini 10, Mike’s first assignment was to specialize in the development of
the program’s spacesuits. He then served as backup pilot for the Gemini 7 mission.
Prior to the 1967 Apollo 1 fire, which claimed three astronauts’ lives, he was training for the
then-planned second crewed flight of the Apollo program. In the wake of the tragedy, the
mission was canceled.

Although he did not fly on Apollo 8 due to needing surgery, Mike still played an important role
on the 1968 mission, serving as CapCom, or capsule communicator, from inside Mission
Control in Houston. It was Mike who informed the crew that they were good to break the bonds
of Earth’s gravity and set course for the moon with the words “Apollo 8, you are go for
TLI!†(TLI stood for trans-lunar injection).

After Apollo 11 and spending 21 days in quarantine to protect against any possible “moon
germs,” riding in ticker tape parades in New York and Chicago, attending a state dinner,
addressing a joint meeting of Congress and touring 22 countries in 38 days, Mike resigned
from NASA in January 1970.

After the moon

Recruited by the Nixon Administration, Mike accepted a position as Assistant Secretary of
State for Public Affairs, but found he did not enjoy the job and left after a year to become the
first director of the Smithsonian Institution’s National Air and Space Museum.

Mike advocated for its funding and oversaw the museum being built once its budget was
approved by Congress. He presided over the museum’s opening on July 1, 1976, when his
Apollo 11 command module, Columbia, and many of his own personal effects flown on the
mission went on public display.

Mike headed the National Air and Space Museum until 1978, when he became undersecretary
of the Smithsonian. He completed Harvard Business School’s advanced management program
in 1974 and took a position as vice president of LTV Aerospace, a NASA contractor, in 1980.
In 1982, Mike retired from the Air Force with the rank of Major General. In 1985, he left LTV to
found his own consulting firm.

In addition to “Carrying the Fire,” he authored “Flying to the Moon and Other Strange
Places” (Farrar, Straus and Giroux, 1976), “Liftoff! The Story of America’s Adventure in
Space” (Grove Press, 1988) and “Mission To Mars: An Astronaut’s Vision Of Our Future” (Grove
Weidenfeld, 1990).

For his service to the space program, Mike was honored with many awards, including the
NASA Exceptional Service Medal, the NASA Distinguished Service Medal and the Legion of
Merit. With his Apollo 11 crewmates, he was bestowed the Collier Trophy, the Presidential
Medal of Freedom, the Harmon Trophy and the Congressional Gold Medal.

Of all the honors he received, Mike was most proud to be named a Fellow in the Society of
Experimental Test Pilots, the prestigious international society founded in 1955 that represents
the men and women who advance aerospace vehicles through flight test programs.

Outside of his professional career, Mike enjoyed physical challenges, including running in
marathons and competing in triathlons. On his 50th birthday, he ran 50 miles as a personal
celebration. In his retirement, he took up watercolor painting and attended art classes to
improve his skill. His chosen subjects were the aircraft that he flew and natural surroundings of
the Florida Everglades.

Above all else, he relished the time he spent with his family. It was for that reason that chose to
leave NASA when he did, possibly missing a chance to walk on the moon in favor of spending
more time with his children and grandchildren.

He was predeceased by his wife, Patricia Finnegan Collins. He was also predeceased by his
brother, James Lawton Collins, Jr., his sister Agnes Spera and his son Michael L. Collins.
He is survived by his sister, Virginia (Nuchi) Collins Weart and by his two beloved daughters,
Kate Collins (and husband Charlie Newell) and Ann Collins Starr (and husband Chris Starr). He
had seven grandchildren: Matt Starr, Jake Newell, Jane Starr, Julia Starr, Luke Newell, Katie
Starr and Tim Starr. He is also survived by many cherished nieces and nephews.

Mike always faced the challenges of life with grace and humility, and faced cancer, his final
challenge, in the same way. We will miss him terribly. Yet we also know how lucky Mike felt to
have lived the life he did. We will honor his wish for us to celebrate, not mourn, that life.
