Ginny and Percy

NASA’s Ingenuity Mars Helicopter has a new mission. Having proven that powered, controlled flight is possible on the Red Planet, the Ingenuity experiment will soon embark on a new operations demonstration phase, exploring how aerial scouting and other functions could benefit future exploration of Mars and other worlds.

So “Ginny,” her primary proof of concept mission over, will serve as a scout for “Percy,” flying ahead of the rover to survey locations Perseverance will investigate in its search for life on Mars. It will also help mission planners plot the best routes for Percy to follow. She’ll fly ahead and land and wait for the rover to catch up. That’s Teamwork.

It got crowded on the International Space Station with the arrival of “Crew-2,” SpaceX’s second regular and third actual flight taking humans to the ISS (there was a test mission known as “Demo-2”). There hadn’t been eleven people on board since the Space Shuttle era.

There were other milestones as well. This was SpaceX’s first reused crew capsule to reach the orbiting platform and the first crewed mission with a reused Falcon 9 rocket. The Crew-2 astronauts themselves made history when they started boarding. This was the first time SpaceX had carried passengers from three different agencies (NASA, ESA and JAXA).

The overcrowding on the ISS came to an end just a few days later with the spectacular nighttime landing of SpaceX’s Crew-1 “Resilience” capsule with four astronauts on board. They landed in the gulf of Mexico just before 3am Eastern Time. But with cameras tuned for night the scene was clearly visible in spite of the pitch dark ocean lighting.

Crew Dragon Resilience will add to its time in space on its next mission launching the privately-funded Inspiration4 crew on a multi-day Earth orbit mission targeted for September.

A Breath of Fresh Air

It some ways it was certainly unusual. But mostly its normalcy made it a breath of fresh air. For more than an hour President Joe Biden delivered a report to Congress, the nation, and the world on the state of the state one hundred days into his administration. He laid out the achievements already accomplished, the programs now under way, and the proposals he is sending to Congress for enactment into law.

One way the speech was unusual was that there were two women behind the president. Presiding over the joint session of Congress were Vice-President Kamala Harris, who is President of the Senate, and Nancy Pelosi, the Speaker of the House of Representatives. That was a historic first. Another way was that the chamber, which normally holds 1,600 people for these events, was limited to 200 by pandemic protocols. The audience members were socially distanced and most were masked.

Helicoptering on Mars – Really

A team of very smart humans flew a helicopter by remote control off the surface of Mars on April 19, 2021. It is easier to type that sentence than it is to truly appreciate the accomplishment.

The Mars Helicopter, named Ingenuity, weighs just four pounds. It is a proof of concept demonstration. That means it’s mission is just to prove that it works. It did. And it was the first time humans have achieved powered and controlled flight on another planet.

Ingenuity hitched a ride on the Perseverance rover. I wrote about Perseverance after it landed. Nicknamed “Percy,” it has a detailed science mission to look for signs of life on Mars. But first it was tasked with dropping Ingenuity, “Ginny,” onto the Martian surface, backing away and watching while the Ingenuity team tried to make their little drone fly.

This short video, taken by Perseverance, shows the entire first flight:

Mars is the closest planet to Earth, and has entranced humans since the beginning of recorded history. It is behind a paywall, but if you have access the Washington Post has produced a wonderful overview of the history of Mars exploration and the plans for this mission, known as Mars 2020.

The challenge for Ingenuity is that the atmosphere on Mars is only one percent the density of that of Earth. Strange at it seems, most of our airplanes effectively pull themselves through the atmosphere like a corkscrew pulls a cork out of a bottle. On Mars there is very little atmosphere to grab hold of. That produced a design for Ginny that meant a very low weight craft with relatively big rotors spinning at very high speeds. And of course the fact that radio signals take many minutes to get from Earth to Mars meant that Ginny, like Percy, has to be fed instructions but is then on its own to execute them. We humans find out if the task was achieved minutes or even hours later.

This was an amazing feat and in so many ways a tonic for the times in which we live. There are those who question the value of this kind of scientific research and exploration. Surveys show many people perceive the cost to be high. But in fact, the NASA budget is a tiny fraction of the military’s budget. The military budget just for its new Space Force and Space Command is higher. The debate is heated, but a majority of Americans favor continued funding for NASA.

Studies show that for every dollar spent on NASA, more than $8 is added to the economy. And you had only to watch the control room crew as the data came in documenting Ginny’s first flight on another planet to see how this research is exciting new generations of explorers. When I was a child watching the Mercury astronauts I saw images almost exclusively of white men wearing white shirts and narrow black ties. We now know that behind the scenes there were crucial if unsung members of the team kept hidden from the cameras. Today’s teams represent men and women across all demographics. If the United States is to remain competitive and really matter in the 21st century we need to do more to encourage all young people to pursue scientific careers.

Now that the helicopter concept has been proven, scientists and engineers planning future missions to Mars and elsewhere have access to a treasure trove of research as they explore the use of flying vehicles on their missions. There are, for example, many locations on Mars that are inaccessible by rover but are of great interest to planetary scientists. There is also an upcoming mission to Titan, Saturn’s largest moon. Titan has an atmosphere denser than that of Mars. There is already a helicopter named Dragonfly planned for that mission which is now scheduled to launch in 2026, arriving in 2034.

Even while waiting for Ginny to finish her testing, Percy is working. The MOXIE technology demonstration aboard Perseverance successfully extracted oxygen from the thin Martian atmosphere—a critical component for life support so humans can breath on the Red Planet and produce rocket fuel for the trip home.

The continuing plan for Mars 2020 is for Ingenuity to make several more test flights over the next few weeks, each one pushing the helicopter to fly higher and further away. A second flight was made on April 22nd, a third on April 25th. As often happens with technology demonstrations, it may well be pushed beyond its limits and crash on the surface. In any event, by the end of April it will be left behind as Perseverance leaves the scene to begin it’s own exploration of the Martian surface, which will include the collection of samples for retrieval on later flights.

You read that right. The Mars 2020 mission will be collecting samples of Mars to be picked up by later flights. Stay tuned.

Update – Ingenuity Tests Extended

After a successful fourth flight, NASA announced it would extend the test flight program for Ingenuity for another 30 days. Ginny’s mission was slated to end at the end of April. Now NASA plans to test the chopper’s ability to be a “scout” for future exploration by the Perseverance rover and future missions.

Perseverance will be farther from Ingenuity during the new flight phase, but the team thinks that the pair will still be able to communicate effectively. Additionally, Perseverance will not take the time to document the flights Ingenuity makes during its extended mission.  NASA will continue to provide updates on Ingenuity’s progress here.

Infrastructure for the 21st century

I long for the days when I could have a rational discussion with someone I disagree on the serious issues of the day without that person spouting a stream of totally unsubstantiated falsehoods. In other words lies. I’m pointing my finger at you, Republicans, almost without exception.

Discussions with Democrats are also often frustrating. But that is because the Democrats include a wide range of differing views and the disagreements are generally over strategy. I’m thinking of you Joe Manchin. Not over the role of government in attempting to solve problems or denying that problems even exist. And Democrats are not inclined to interrupt a serious discussion with a rude critique of your mother’s footwear. I still remember being told, “Your mother wears army boots.” I was on the first grade playground at recess at the time.

Republicans will call you every name in the book at the drop of a hat. They will insult your relatives, living and dead. And charge you with a wide variety of crimes without the slightest bit of evidence. They also live in an alternate universe where up is down, down is up, and things you can see right before your own eyes are somehow not true. They revere the framers who wrote our Constitution, except when they ignore it.

Republican hypocrisy knows no bounds:

  • Senate rules are sacrosanct unless they need to be broken to thwart a Democratic proposal.
  • Deficits are bad but only if there is a Democrat in the White House.
  • The purpose of the federal government is to “provide for the common defense,” quoting the magnificent preamble to our Constitution, ignoring the fact that the phrase is part of a list and imminently following are the words, “promote the general welfare.”
  • Infrastructure means roads. That’s it. Roads.

Let’s put the debt debate aside for now except for to state that the evidence is clear, economics is an art, not a science. We really don’t understand what it is going on. Starting with Ronald Reagan, Republican, yes, Republican presidents have greatly increased the national debt by cutting taxes and increasing defense spending. Yet the inflation that was predicted by my college economics teacher (we used Paul Samuelson’s Principles of Economics) did not really appear. Go figure. For more right now I refer you to a great piece by John Oliver.

What this means is, while we should be watchful, and Fed Chairman Jerome Powell seems to be, we do not have to be afraid of some Covid related economic stimulus. Republicans opposed the latest round of Covid economic payments even when Donald Trump asked for them. We also do not need to be afraid of a big infrastructure program. The Republicans are outraged at the infrastructure program, arguing that it will increase the debt and complaining that Democrats are extending the traditional definition of infrastructure.

Republicans don’t seem to have a problem with repairing the nation’s highways and bridges. Republican Dwight Eisenhower signed the legislation that created the Interstate Highway System in 1956 after all. But Republicans like highways that connect towns in rural America. Transportation projects that benefit urban areas do not get their approval. I take the New Jersey Transit train under the Hudson to Manhattan and always wonder if the crumbling tunnel, built in 1910, is going to cave in on the 200,000 people who use it every day. In 2012 the tunnel was inundated with millions of gallons of salt water during Super Storm Sandy. The water left behind corrosive chlorides, which continue to damage the already aged concrete and wiring. A Republican New Jersey Governor, Chris Christie, and a Republican President, Donald Trump, each killed a project to build a replacement.

But where the Republicans most throw up the roadblocks is where it comes to infrastructure they claim is outside of the “traditional” definition of the word. I disagree. But I also don’t care. We do not live in a stagnant word. We can be respectful of our traditions but should not be afraid to change them for the public good.

So I am on board with what some analysts are calling “Social Infrastructure”:

Social infrastructure can be broadly defined as the construction and maintenance of facilities that support social services. Types of social infrastructure include healthcare (hospitals), education (schools and universities), public facilities (community housing and prisons) and transportation (railways and roads).

I do not understand why people cannot see that the nation depends on the health of its people, and the safety, and quality of its schools. We also need a 21st century power grid and high-speed rail would be nice. Child care for working parents is an economic necessity. In an information driven society, broadband connections for the entire population are essential. Faced with tremendous world-wide competition education, research and development are all that stands between America and second-class status.

The public seems to understand this even if the Republicans do not. A Quinnipiac University National Poll finds the Infrastructure Plan is popular with the public:

And even more popular if corporate taxes fund it as President Biden has proposed:

Last but not least, expenditures on infrastructure, traditional and 21st century alike, have a large multiplier factor. Put simply, they pay off many times over. The benefits spread throughout the economy. The Eisenhower creation of the Interstate Highway System is credited with creating the long post-war expansion of the American economy. Studies show tax cuts for rich people and fiscal policies which benefit Wall Street do not have this positive effect. The proposed infrastructure projects should be seen as an investment in America’s future.

Biden Meets the Press

For weeks the right-wing bobble heads on cable complained that President Joe Biden had not yet held a news conference. As if he didn’t have a few other things on his plate as he worked to clean up the mess his predecessor had left behind. This week he did face the press in a formal setting and, of course, the bobble heads complained about his performance.

I’m old enough to remember when reporters asked presidents questions and filed stories based on the answers they received. Today reporters ask questions and the stories are made up of the opinions of people I have never heard of speaking with great authority about things which have nothing to do with the answers.

We Can Still Persevere

In the middle of this challenging time of pandemic and politics, a group of dedicated scientists on February 18, 2021 landed a car-sized rover designed to explore the crater Jezero on the surface of Mars. The picture above might look like one of NASA’s animations depicting the event. But it is not. The picture is real, taken by the HiRISE high resolution camera on the Mars Reconnaissance Orbiter, which has been circling the planet since March 10, 2006. The photo clearly shows the rover, named Perseverance, beneath its huge parachute. To take this photo, the crew directing the Orbiter had to calculate in advance the precise timing and position so they could instruct the Orbiter to aim its camera and catch Perseverance in flight.

The Entry, Descent and Landing phase of the mission is nicknamed the “seven minutes of terror.” It started when Perseverance entered the thin Mars atmosphere, travelling at almost 12,500 miles per hour. It ended seven minutes later when the rover, executing a Rube Goldberg machine-like series of maneuvers, touched down at a speed of less than two miles per hour. Anything faster and Perseverance would have been shattered into a collection of worthless parts spread across the Martian surface.

Trump Trial #2 – sine die

US Senate

And so it is over. The second trial of Donald J. Trump, the only president to have been impeached twice, has adjourned. And Trump is now also the only president to have been found not guilty twice by the U.S. Senate. In the final tally, 57 senators, including 7 Republicans, found Trump guilty of high crimes and misdemeanors for inciting the mob that went on to breach and vandalize the Capitol, and to injure and kill law enforcement personnel. Forty-three senators found Trump not guilty. A supermajority of 67 being constitutionally required for conviction, the result was not guilty.

But only a handful of Trump’s most loyal supporters rushed to the cameras to proclaim that their leader had been exonerated by what goes down as the most bipartisan impeachment in history. The senators, and the world, saw the video of senators and members of the House fleeing for their lives during the attack on January 6th. They saw the Vice-President, Mike Pence, and his family being ushered away from the senate chamber by the Secret Service. They viewed Trump’s tweet of rage following Pence’s refusal to attempt an unconstitutional coup by rejecting of the voter’s will saying, “Mike Pence didn’t have the courage to do what should have been done to protect our Country and our Constitution.” They heard testimony that Trump had sent that tweet moments after receiving word that the Vice-President’s life was at risk.
