Ed Stone, who ran the Voyager missions for a half century, passes away at 88

9:54 am

Ed Stone, who was the project scientist for both Voyager missions to the outer solar system and beyond for a half century, passed away at 88 on June 9, 2024.

From 1972 until his retirement in 2022, Stone served as the project scientist from NASA’s longest-running mission, Voyager. The two Voyager probes took advantage of a celestial alignment that occurs just once every 176 years to visit Jupiter, Saturn, Uranus, and Neptune. During their journeys, the spacecraft revealed the first active volcanoes beyond Earth on Jupiter’s moon Io, and an atmosphere rich with organic molecules on Saturn’s moon Titan. Voyager 2 remains the only spacecraft to fly by Uranus and Neptune, revealing Uranus’ unusual tipped magnetic poles, and the icy geysers erupting from Neptune’s moon Triton.

Stone was also head of JPL from 1991 to 2001, during the time it built and flew the Mars Pathfinder mission, which sent the first rover to Red Planet. That mission revitalized the entire American Mars exploration program for the next three decades.

Stone was one of the giants of American space exploration during its formative years. He leaves behind a legacy that will be difficult to match, highlighted most of all by both Voyager spacecraft, which outlived him.

Bill Anders, the thoughtful astronaut who liked to go fast

The death of Apollo 8 astronaut Bill Anders on June 7, 2024 requires that I give the public my own personal taste of the man, whom I met and interviewed when I was writing my 1998 history of the Apollo 8 mission to the Moon, Genesis: the Story of Apollo 8.

The first time I met Bill Anders was in 1997. Anders had told me to fly into Los Angeles for our first interview. A few days before my arrival, however, his wife Valerie realized that both she and Anders would not be in Los Angeles, but in San Diego.

Rather than have me change flights, Anders agreed to drive up to LA, pick me up at the airport, and drive me to San Diego so I could interview Valerie. During the two hour drive I would be able to interview him.

Anders was waiting for me as I exited the terminal. As I have noticed routinely, he seemed much smaller than I expected, as does every astronaut at first meeting. Anders guided me to a low-slung sports car, which he slid into with ease. I — being 6′ 4″ — had to crowbar my way in.

And then Anders demonstrated instantly one reason he was chosen to fly to the Moon. He started the car, and backed out of the parking space and out of the lot at what seemed to me to be about seventy miles an hour. And he did it with total control.

Apollo 8 astronaut Bill Anders, 90, killed in plane crash

8:59 pm

Earthrise as seen from Apollo 8, December 1968

Apollo 8 astronaut Bill Anders, 90, who took the iconic Earthrise picture (to the right and oriented as he framed it when he snapped it), was killed today when the plane he was piloting went down in the waters near the San Juan Islands off the coast of the state of Washington.

A report came in around 11:40 a.m. that an older-model plane crashed into the water and sank near the north end of Jones Island, San Juan County Sheriff Eric Peter said. Greg Anders confirmed to KING-TV that his father’s body was recovered Friday afternoon.

Only the pilot was on board the Beech A45 airplane at the time, according to the Federal Aviation Association.

I will have more to write about Anders later, whom I had met and interviewed many times when I was writing Genesis: the Story of Apollo 8. Of all the astronauts, he was probably the most thoughtful about matters outside of engineering, space exploration, or aviation.

The recovered diary of Columbia’s Israeli astronaut now on loan to Israel’s national library

9:50 am

One page from Ilon Ramon's space diary
One page from Ilon Ramon’s space diary

According to a May 29, 2024 announcement by the National Libary of Israel, the recovered diary of astronaut Ilan Ramon — who died when the space shuttle Columba broke up on its return to Earth — has now been transferred from the Israel Museum to the National Library of Israel so that it can finally be put on display.

The diary, a personal and national treasure, should have disintegrated along with the shuttle and its crew, but a few weeks after the disaster, to the surprise of the search party, someone found the remains of the diary on a muddy patch of land in Texas.

How is it possible that it survived? It withstood the explosion, and then a journey of several kilometers till it hit the earth. No one knows for sure, but leading researchers in the field believe that due to the light weight of the pages, the diary didn’t fall directly to the ground but probably glided slowly downwards, carried on wind currents that eventually allowed for a soft landing. Most of the damage to its pages probably only happened after it reached the ground, resulting from the humid conditions in the marshy area where it landed.

Since then the Israel Museum has been carefully documenting its contents, which included daily accounts by Ramon of his experience in space. One example:

Dwayne O’Brien – We Remember

6:01 pm

An evening pause: To the men who flew the planes.

And all who’ve coursed through hostile skies,
Know that freedom requires a sacrifice,
To those who paid the highest price,
We remember.

With a place of honor so deserved,
For what flesh and blood and steel have earned,
That may the glory be reserved,
For the colors they so bravely served.

Keep them flying, keep them flying,
So that all who see them will know,
That our freedom was won by the blood that flowed,
And we remember.

Salomé’s Dance

6:01 pm

An evening pause: Music by Charles Barber. This comes from the 1913 silent film, Salomé, based on an Oscar Wilde play. Rarely seen, the movie represents a very early attempt to do something “edgy”. It succeeds about as well as modern “edgy” films, showing us a very shallow representation of human existence. But the visuals give us a glimpse into that early film world, when sets and costume were usually the only way to show something strange and striking.

Real Space – Every Space Station Size Comparison

6:01 pm

An evening pause: Some quick visual space station history. Note how almost all the non-U.S. stations are essentially assembled using revisions of the same early Soviet-era modules. Note too how the future private stations are all very different from each other. The contrast illustrates the difference between what you get when governments control everything, and when competition and freedom rule.

Apollo astronaut Tom Stafford passes away at 93

9:45 am

Apollo 10 astronaut Tom Stafford, who also flew two Gemini missions as well as the Apollo-Soyuz mission, passed away yesterday at the age of 93.

Stafford’s first flight was on Gemini 6, which achieved the first rendezvous in space when it maneuvered close to Gemini 7 during its two week mission. He then flew on Gemini 9, which was to attempt the first docking but was stymied when the shroud on the Agena target vehicle failed to release, blocking the docking port. The crew could only rendezvous again.

Stafford then commanded Apollo 10, the dress rehearsal for the lunar landing, flying his lunar module to within about ten miles of the Moon’s surface. His final mission was Apollo-Soyuz, the first joint mission between the United States and the Soviet Union.

Of the 24 Apollo astronauts that flew to the Moon, only seven still live. A truly great generation of Americans, possibly the greatest generation of all, is slowly leaving us.

An evening pause: The visuals come from the 1927 German film by Fritz Lang, Metropolis, and cover the scene dubbed “Maria’s Dance.” You can see the full movie here, as well as many other places on line.

Hat tip Judd Clark, who adds, “To understand what’s going on here, one needs to see the whole movie, preferably the latest restored version, and to really understand, one needs to read Lang’s wife Thea Von Harbou’s book “Metropolis”.

Simon Sinek – How great leaders inspire action

6:01 pm

An evening pause: Though I do not think his hypothesis goes far enough, this short TED talk posits some intriguing ideas about leadership. And it seems somehow appropriate today on the Ides of March, which also makes me wonder what Julius Caesar (and other successful leaders, both good and evil) would think of these ideas.

Abraham Lincoln – an annual tribute to celebrate his birthday

6:01 pm

An evening pause: The memory of this man and what he stood for and accomplished must not be forgotten, which is why I try to celebrate his memory each year with a tribute on his birthday. As I wrote in 2021,

[T]hough he freed the slaves, I think Lincoln’s most enduring contribution to American history, a contribution that now has sadly been lost, was his limitless good will for everyone, even to those who hated him and wished to kill him. Had he not been assassinated, American history might have been far better because Lincoln would have had the clout to ease the worst elements of Reconstruction, while forcing through reforms in the former southern slave states.

Those reforms did not happen until the civil rights movement of the 1960s, and are now being abandoned in the 2020s by black supremacists in the academic community who are imposing new racist Jim Crow laws nationwide, designed to favor blacks and other minorities.

Listen to the words of the first song, which was a Lincoln campaign song. He stood for freedom for all, and put his life on the line for that principle. From the pictures you can see the evolution of this kind-hearted but determined man from youth to mid-age, with all the troubles of the Civil War reflected in his face and mouth.

Computer problem on Voyager-1 remains unsolved

9:54 am

Engineers remain baffled over a computer issue that has prevented the receipt of any data since November 2023 from Voyager-1, floating some 15 billion miles away just outside the solar system in interstellar space.

In November, the data packages transmitted by Voyager 1 manifested a repeating pattern of ones and zeros as if it were stuck, according to NASA. Dodd said engineers at JPL have spent the better part of three months trying to diagnose the cause of the problem. She said the engineering team is “99.9 percent sure” the problem originated in the FDS [Flight Data Subsystem], which appears to be having trouble “frame syncing” data.

So far, the ground team believes the most likely explanation for the problem is a bit of corrupted memory in the FDS. However, because of the computer hangup, engineers lack detailed data from Voyager 1 that might lead them to the root of the issue. “It’s likely somewhere in the FDS memory,” Dodd said. “A bit got flipped or corrupted. But without the telemetry, we can’t see where that FDS memory corruption is.”

Since November the only signal received from Voyager-1 is a carrier signal that simply tells engineers the spacecraft is alive. Though the effort continues to try to fix the spacecraft, the odds of bringing it back to life are becoming slim, especially because its power supply will run out in 2026 at the very latest. Even if they manage to fix the issue now, the spacecraft has only a short time left regardless.

Considering the computers on this spacecraft, as well as its twin Voyager-2, have been operating continuously for almost a half century since their launch in 1977, their failure now is nothing to be ashamed of. The engineers that built both did well, to put it mildly.

As for Voyager-1’s future, even dead it will fly on into interstellar space, eventually getting within 1.5 light years of a star in the constellation Camelopardalis.

The future of astronomy, as seen by PBS News in 1991

6:01 pm

An evening pause: Today is the 75th anniversary of the moment astonomers took the lens cap off the Hale Telescope at Palomar, what astronomers call “first light.” In honor of this anniversary, tonight’s evening pause is a somewhat well-done news piece produced by PBS in 1991, describing the state of ground-based astronomy at that time, which was actually another key moment in the history of astronomy. After decades of no advancement following the Hale telescope, the field was about to burst out with a whole new set of telescopes exceeding it significantly, based on new technologies. We today have become accustomed to those new telescopes, but in 1991 they were still incomplete or on the drawing board.

This was also after the launch of Hubble but before it was fixed, so this moment was also a somewhat dark time for astronomy in general. Watching this news piece gives you a sense of history, as seen by those living at that time. It also lets you see some good examples of the standard tropes of reporters as well as some astronomers. They always say this new telescope (whatever and whenever it is) is going to allow us to discover the entire history of the universe, even though it never can, and never will.

Dave Brubeck Quartet – Golden Brown

6:01 pm

An evening pause: This video is not what it seems. The sax player, Lawrence Mason, has created a cover of this Dave Brubeck song by editing and playing over the Dave Brubeck quartet playing another song in 1965. As he notes on the youtube page, he did it as a tribute to “Paul Desmond (saxophonist with the Dave Brubeck quartet – the anniversary of his death is at the end of this month) [May 2020].”

Secretariat – Triple Crown Races

6:01 pm

An evening pause: If you have never seen the Triple Crown victories by Secretariat in 1973, you need to watch this video. It will take your breath away. In the first two races jockey Ron Turcotte appears to let the pack take the lead at the start because he knows Secretariat can’t stand being behind. In the last, it is as if the horse wanted to prove to everyone that there was no horse now or ever that was faster. From the youtube webpage:

Secretariat (March 30, 1970 – October 4, 1989), also known as Big Red, was a champion American Thoroughbred racehorse who is the ninth winner of the American Triple Crown, setting and still holding the fastest time record in all three races. He is widely regarded as one of the greatest racehorses of all time. He became the first Triple Crown winner in 25 years and his record-breaking victory in the Belmont Stakes, which he won by 31 lengths, is widely regarded as one of the greatest races in history.
