Space (part 5) - Perseverance

 


Perseverance!

Its definition according to Merriam-Webster:

continued effort to do or achieve something despite difficulties, failure, or opposition : the action or condition or an instance of persevering : STEADFASTNESS

These qualities capture the essence of the latest NASA mission to Mars.  Thomas Zurbuchen, the associate administrator of the agency's Science Mission Directorate, explained:

"Yes, it's curiosity that pulls us out there, but it's perseverance that does not let us give up." 

Perseverance was chosen from its naming contest for students K-12.  The winning essay was written by seventh grader Alex Mather. For the full story:  What's in a name: Why NASA chose 'Perseverance' for its next Mars rover

And for an overview of this latest mission: Mars Perseverance Mission Overview

Perseverance was launched, July 30, 2020, in the midst of the COVID-19 crisis, another testament to its name:



February 18, 2021, Perseverance successfully landed on Mars, a shown in this animation:


Yea!

Modern marvels of technology recorded the actual landing:




And what a magnificent view!

Thus Perseverance joins her four sister rovers: Sojourner, Spirit and Opportunity,  and Curiosity.

So the Maritain Chronicles continue as we persevere!

Space (part 3): Apollo 11 Golden Anniversary

Aldrin Apollo 11/wikipedia.com


September 12, 1962

President John F Kennedy offered this vision for our country: Go to the moon!



"We choose to go to the moon," the president said.
"We choose to go to the moon in this decade
and do the other things,
not because they are easy,
but because they are hard,
because that goal will serve to organize
and measure the best of our energies and skills,
because that challenge is one that we are willing to accept,
one we are unwilling to postpone,
and one which we intend to win,
and the others, too."

Reference: JFK's 'Moon Speech' Still Resonates 50 Years Later

July 20, 1969

We aimed for the moon.
And before the end of the decade, 
we hit our target.

Space (part 2): Earthrise - 1968

Earth Rise/wikipedia.com

Fifty years ago - 1968 

Earth was a troubled place

Some highlights in America at that time:

* The unpopular Vietnam War and more unpopular draft

* Assassination: Martin Luther King Jr., Robert F. Kennedy

* Riots at the Chicago Democratic National Convention

* Counter-culture hippie movement

* President Lyndon B. Johnson and President Elect Richard M. Nixon

A popular TV show at that time was The Smothers Brothers Comedy Hour (1967 - 1970). The show featured s labor of love by filmmaker Chuck Braverman, described as:

A quick trip through the USA during the turbulent 1968




But in December 1968, Apollo 8  sent astronauts, Frank Borman, Jim Lovell and Bill Anders, orbiting the moon for the first time in history.

On their Christmas Eve broadcast, the crew transmitted the iconic Earthrise photo while reading from Genesis, as shown below: 




Back to the future, 50 years later, these still are troubled times.

As we finish the year 2018, words from a hymn, This is My Father's World come to mind. And the last verse, not always included in other renditions, gives the reason we celebrate the birth of the Savior of the world:

This is my Father’s world:
Oh, let me ne’er forget
That though the wrong seems oft so strong,
God is the ruler yet.

This is my Father’s world,
The battle is not done:
Jesus who died shall be satisfied,
And earth and Heav’n be one.



And in the closing words of astronaut Frank Borman:


"And from the crew of Apollo 8, 
we close with good night, good luck, 
a Merry Christmas, 
and God bless all of you -
 all of you on the good Earth."

Pray4America (part 15) - Communion on the Moon

Wikipedia/First Man on Moon 1969 Issue-10c 


On July 20, 1969 - 45 years ago - two men, Neil Armstrong and Buzz Aldrin, were the first humans to walk on the moon. [reference:  First Man on the Moon]

Much has been recorded on this epic event. But after those first few minutes after they landed on the moon, Buzz Aldrin said, "This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way."

The clips below is the rest of the story:




Here is an account attributed to Buzz Aldrin:

"In the radio blackout, I opened the little plastic packages which contained the bread and the wine. I poured the wine into the chalice our church had given me. In the one-sixth gravity of the moon, the wine slowly curled and gracefully came up the side of the cup. Then I read the Scripture, 'I am the vine, you are the branches. Whosoever abides in me will bring forth much fruit. Apart from me you can do nothing.'

"I had intended to read my communion passage back to earth, but at the last minute [they] had requested that I not do this. NASA was already embroiled in a legal battle with Madelyn Murray O'Hare [sic], the celebrated opponent of religion, over the Apollo 8 crew reading from Genesis while orbiting the moon at Christmas. I agreed reluctantly. I ate the tiny Host and swallowed the wine. I gave thanks for the intelligence and spirit that had brought two young pilots to the Sea of Tranquility . It was interesting for me to think: the very first liquid ever poured on the moon, and the very first food eaten there, were the communion elements."
 [reference: Commoonion]

Where can I go from your Spirit?
Where can I flee from your presence?

If I go up to the heavens, you are there;
if I make my bed in the depths, you are there.

If I rise on the wings of the dawn,
if I settle on the far side of the sea,

even there your hand will guide me,
your right hand will hold me fast.

Science 101 (part 3) - From Galileo to Apollo

Wikipedia.com/Apollo 11 Insignia


Man on the Moon - July 20, 1969

July 20th marks another anniversary of the moon landing of Apollo 11.  Neil Armstrong took the first steps and said these words while a large part of the world was watching -



Much has been written and recorded about his epic event.  And for the greatest moments, check out: Apollo 11: First Men on the Moon | The Greatest Moments in Flight | Space.com

Share photos on twitter with Twitpic
The Saturn V carrying Apollo 11, the first crewed mission to the Moon, soared into space 

Almost a year ago, August 25, 2012, Neil Armstrong passed away, "slipped the surly bonds of earth" to "touch the face of God."  (reference:  Neil Armstrong Biography - Facts, Birthday, Life Story - Biography.com)   The video below is a "Blue and Beautiful" tribute.




Physics and Engineering for Apollo 11

It was a remarkable achievement of science and engineering as well as piloting skill and will power to take on this great leap of human exploration.



How did this all work? Here is abglimpse that explains some of the physics involved - How Hard Is It to Land on the Moon? New Space Game Gravitates Towards Space Physics « Mad Science

The physics of Galileo and beyond ...

Much of the moon shot was made possible by understanding the laws of physics.  And Galileo was a pioneer in modeling the effects of gravity on masses.  In the1500s, Aristotle's description of nature had reigned for 2000 years.  But Galileo challenged this model with his hypotheses - all objects fall (with no air resistance) fall at the same rate.

Such is seen below as this experiment carried out on the Leaning Tower of Pisa:



And Galileo wins!

For fun, try this game:  Wolfram Demonstrations Project: Galileo's Experiment at the Leaning Tower of Pisa

On the moon - practically speaking - there is no air resistance.  Here during  the Apollo 15 mission, Commander David Scott drops a feather and hammer.



Bazinga!    Galileo wins, again!

Galileo has been attributed to the assertion of the Equivalence Principle that says the inertial mass is proportional to the gravitational mass.

So we have an example of two experiments that corroborate the Equivalence Principle from the Tower of Pisa and the moon. (reference:  Millersville University - Experiment of the Month - Inertial and Gravitational Mass)

What's next?

STEP into the Future ...

A more sensitive experiment is taking shape in the STEP program:  The Satellite Test of the Equivalence Principle (STEP).

Wikipedia - Spacetime Curvature

The proposed science experiment in space boasts an accuracy in measurement of 1 part in 10 to the18th power - that is, 1 in 1,000,000,000,000,000,000.  When or if this satellite launches, we will have an opportunity to gather more data. (reference:  STEP – The Satellite Test Of the Equivalence Principle (PDF) )


With this small STEP, will three be a charm and Galileo wins, again?

You betcha.

AI (part 2) - How Curiosity got our groove back

Mars and Syrtis Major


Free  - Free
A trip 
To Mars
For 900 
Empty jars

Burma-Shave

This ditty is a bit of nostalgia.

Burma-Shave was a brush-less shaving cream company, started in 1925.  Eventually, the company was sold to Philip Morris in 1963 and faded from our consciousness.  But Burma-Shave has left its mark in Americana for its clever advertising jingles displayed on highway signs.
(reference:  Feeling nostalgic? Now you'll rave! Here's the story of Burma Shave)

Yes, back in 1955 Burma-Shave did offer a free trip to Mars as a promotional gimmick as shown in the ditty above.  (reference:  Burma-Shave jingles 1955)  

But the company did not count on one determined man, Arliss French, from Appleton, Wisconsin to take them up on it.  Mr. French gathered those 900 empty jars.  And Burma-Shave did keep their word and sent Mr. French and his wife to Mars.  Only it was spelled - Moers (pronounced "mars") and it was in Germany, that is.
(reference: Snopes - True)

Burma-Shave's jingles and sending a customer to Mars (though in Germany) in 1955, two years before Sputnik, attest to American Ingenuity (AI).

This humorous story also shows the fascination we have had with the Red Planet. Just google "Mars."  (Speaking of Google, as we have Google Earth, we have Google Mars.  Enough said.)   But according to the Science Fiction of the 1950s, we are long overdue in sending men to the Mars - check out:  Mars Science Fiction.
  
The future isn't what it used to be ...
Neil Armstrong in 1969

On the topic of space travel, one of the heroes of American Ingenuity and Exceptionalism is Neil Armstrong, the first man on the moon, who passed away recently (August 25, 2012).

Though quiet many years after the moon walk, Neil Armstrong emerged in 2010 to speak out against the changing direction of NASA as its budget was being slashed and the Space Shuttle mothballed.
(reference: PICKET: Flashback - Neil Armstrong criticized Obama's space plan - Washington Times)

These cuts coincide with last few years when belief in American Exceptionalism and American Ingenuity has been shaken. The $16 trillion debt, high unemployment, deep recession, diminishing world influence lead to the conclusion that America is in decline.
(reference: Is America A Nation In Decline? - Forbes)

One columnist, Craig Shirley, laments the death of Neil Armstrong with the death of American exceptionalism as political elites seem to question that notion. Our clear sense of right/wrong and good/evil have been replaced by "moral equivalency."  Shirley writes that as a young boy, John F. Kennedy inspired him, but as a middle-aged man, Barack Obama dispirits him.
(reference:  Armstrong and the Death of American Exceptionalism)

American Ingenuity and Exceptionalism dead?

As Americans mourn the passing of Neil Armstrong, earlier in the month of August, NASA has breathed new life in the American spirit by the success of the Mars mission  - Curiosity.

SciFi icon William Shatner -  "Captain Kirk" -  narrates the sophisticated technical maneuvering to navigate this rover successfully to the Martian surface.  Below, he details the "Grand Entrance" as it was planned to happen when touching down on Mars - 





And here is what really happened,  August 5, 2012 -



Whew!

White House Science Adviser John Holdren said in a post-landing briefing:

"If anybody has been harboring any doubts about the status of US leadership in space, there is a one-ton automobile sized piece of American ingenuity, and it is sitting on the surface of Mars right now."
(reference:  New York Times - Curiosity Rover Lands Safely on Mars )




Maybe the Mayans were wrong, and 2012 is not the end of the world (only kidding, but check out this link:  2012 End-of-the-World Countdown Based on Mayan Calendar Starts Today - ABC News)
.... but a turning point.

Curiosity is the boost we need 
* to get our groove back *
 and this video below gives a well-deserved victory dance.



What a magnificent tribute to the men and women who pioneered the space program ...

especially a tribute to Neil Armstrong, who personifies 
the spirit of American Ingenuity!
