In the early hours of Sunday morning, SpaceX’s Polaris Dawn crew successfully completed their five-day journey in space, capping off the historic mission with a splashdown in the Gulf of Mexico. The Crew Dragon capsule, carrying four astronauts, landed off the coast of Dry Tortugas, Florida, at 3:37 a.m. ET, marking the conclusion of a mission that included the world’s first commercial spacewalk.

“We’ve made history, and this is only the beginning of what’s possible with private space exploration,” said mission commander Jared Isaacman, the billionaire CEO of Shift4 Payments and key financier behind Polaris Dawn.

The mission achieved several significant milestones, including reaching the highest altitude for human spaceflight in over five decades. The crew orbited Earth at an apogee of 870 miles (1,400 kilometers), surpassing the 1966 altitude record set by NASA’s Gemini 11 mission. This achievement also marked the farthest distance from Earth that humans have traveled since the Apollo program ended in 1972.

For crew members Sarah Gillis and Anna Menon, SpaceX engineers who served as mission specialists, the mission was particularly groundbreaking. The high altitude made them the first women to travel so far from Earth. “It was an honor to be part of this mission, to push the boundaries of human space exploration,” said Gillis.

Splashdown

Despite several major accomplishments during the mission, as always, returning to Earth presented one of its most dangerous challenges. To safely re-enter the atmosphere, the Crew Dragon performed a “de-orbit burn,” orienting itself for the high-speed descent back to Earth. As the spacecraft hit the atmosphere at speeds of 17,000 miles per hour (27,000 kilometers per hour), it endured temperatures as high as 3,500 degrees Fahrenheit (1,900 degrees Celsius), protected by its heat shield.

Slowing down from the friction of the atmosphere, the capsule deployed its parachutes, which further decelerated its descent before it gently splashed down in the Gulf of Mexico. “Welcome back to planet Earth,” the host of SpaceX’s live broadcast exclaimed as cheers erupted in the background.

After splashdown, the capsule briefly bobbed in the water before being retrieved by a SpaceX recovery team stationed nearby. The team hauled the spacecraft onto a boat known as the “Dragon’s Nest,” where the astronauts disembarked after final safety checks. All four crew members, including pilot Scott “Kidd” Poteet, emerged smiling and in good health.

History Making Spacewalk

Last Thursday, Polaris Dawn added another historic first by completing the world’s first commercial spacewalk, also known as an extravehicular activity (EVA). Isaacman and Gillis took turns exiting the spacecraft while it was fully depressurized, marking a new era in privately funded space operations.

Floating just outside the Crew Dragon capsule for roughly 10 minutes each, Isaacman and Gillis tested the functionality of SpaceX’s custom-designed EVA suits, which are engineered to protect astronauts from the harsh conditions of space. “Back at home, we all have a lot of work to do, but from here, Earth sure looks like a perfect world,” Isaacman mused as he took in the breathtaking view during his spacewalk.

The EVA was conducted as part of the mission’s broader goal to test technologies that will be crucial for future deep-space missions, including flights to the Moon and Mars. Despite the high risks involved, the spacewalk was completed without any major issues, a success that SpaceX hailed as a significant step forward for commercial space operations.

A Mission with Purpose

In addition to making history, the Polaris Dawn mission focused heavily on scientific research. The crew conducted nearly 40 experiments during their five days in orbit, with a particular emphasis on understanding space adaptation syndrome, a form of motion sickness that occurs in microgravity. The research conducted on this mission is expected to contribute valuable insights into the long-term health of astronauts during future deep-space voyages.

Sarah Gillis, a trained violinist, also brought her violin onboard and performed Rey’s Theme from Star Wars: The Force Awakens in a symbolic test of SpaceX’s Starlink satellite network, which successfully transmitted the music back to Earth. Meanwhile, Menon read from her co-authored children’s book Kisses From Space during a special video call with patients from St. Jude Children’s Research Hospital, in an effort to raise awareness and support for the hospital.

The mission also tested SpaceX’s next-generation spacesuits, which are designed to offer enhanced protection against the rigors of space, including radiation and extreme temperatures. “These spacesuits will play a vital role in future missions, especially as we prepare for long-term exploration beyond low-Earth orbit,” Menon explained.

The Resilience

The Dragon capsule used for Polaris Dawn, named Resilience, has a storied past. It first flew in 2020 for NASA’s Crew-1 mission to the International Space Station and later in 2021 for the Inspiration4 mission, also led by Isaacman. This marked the third trip to space for Resilience, which continues to demonstrate SpaceX’s commitment to reusability in spacecraft design.

Looking ahead, Isaacman has plans for even more ambitious missions. Polaris Dawn is the first of three planned flights in cooperation with SpaceX, with the next slated to involve a flight to the Hubble Space Telescope to extend its operational life. A third mission is expected to be the first crewed flight of SpaceX’s next-generation Starship rocket.

“This mission is just the beginning of what we can achieve in the future,” Isaacman said. “There’s so much more ahead as we continue to push the boundaries of human spaceflight.”

As SpaceX continues to set new milestones in commercial space exploration, the successful splashdown of Polaris Dawn is yet another reminder of the potential for privately funded missions to lead the charge in the next frontier of human exploration.

Crewed spaceflight is, of course, serious business. Even today, the cost of sending people is so high that mission planners try to maximize every hour a given crew is in space. Still, astronauts and cosmonauts are human beings, and human beings require rest and breaks from constant work even though they are in orbit or on their way to and from the moon.

With that in mind, one of the most enduring traditions in space flight is the crew listening to music in space and even in the final minutes of a countdown. It started in 1961 and continues today, when Polaris Dawn astronaut Sarah Gillis, a gifted classical violinist, performed aboard Crew Dragon ‘Resilience’ while in Earth orbit.

The First Time Music Was Played In A Capsule

The first time music was played inside a space capsule was the first crewed spaceflight: Yuri Gagarin’s world-shaking orbital flight on April 12, 1961. Understandably excited and undoubtedly nervous about his upcoming rocket ride, Gagarin had little sleep the night before his launch. Later, while he was strapped tightly into his seat in the Vostok capsule and with the hatch shut behind him, technical issues delayed the launch multiple times (another long-lasting tradition of spaceflight!), and Gagarin grew restless and bored. Despite being the sole person aboard the spacecraft, Gagarin had little to do but wait for the countdown clock to reach zero and ignition.

Checking in on their passenger, mission controllers asked him how he was faring inside Vostok’s tight confines. Gagarin admitted to being a bit fidgety and suggested that music might help. After a few minutes, the countdown proceeded, and launch controllers figured out how to play records of Russian love songs into the capsule. While the names of those songs seem lost to history, the tradition of music sent to soothe the nerves of cosmonauts continues to this day.

Today, Russian launches are often punctuated by music—even in the final minutes of a countdown. During the last thirty minutes of many Soyuz launches, preparations have been completed: checklists are done, system statuses are confirmed, range safety is verified, the rocket is fueled, and the clock ticks down to zero. Instead of leaving large gaps in air-to-ground communication, Russian mission controllers will often play music over the loop, and that music is often chosen by the cosmonauts themselves.

Here’s an example of music over the Russian command loop, with the countdown passing thirty minutes until liftoff. The music played varies from traditional Russian songs to raucous rock and roll, depending on the crew’s preferences.

Conway Twitty Sings In Russian For Cosmonauts

One of the most endearing stories of the Apollo-Soyuz Test Mission from 1975 is also one that is largely forgotten: American country music superstar and all-time great re-recorded one of his biggest hits in Russian so that it could be played to Soviet cosmonauts Aleksey Leonov and Valeriy Kubasov while they were in orbit with their American counterparts Thomas Stafford, Vance Brand and Deke Slayton.

Astronaut Thomas P. Stafford (in foreground) and cosmonaut Aleksei A. Leonov make their historic handshake in space on July 17, 1975 during the joint U.S.-USSR Apollo Soyuz Test Project (ASTP) docking mission in Earth orbit. This picture was reproduced from a frame of 16mm motion picture film. The American and Soviet spacecraft were joined together in space for approximately 47 hours on July 17th, 18th, 19th, 1975. The Apollo crew consisted of astronauts Thomas P. Stafford, commander; Donald K. “Deke” Slayton, docking module pilot; Vance D. Brand, command module pilot. The Soyuz 19 crew consisted of cosmonauts Aleksei A. Leonov, command pilot; and Valeri N. Kubasov, flight engineer.

Colin Fries, a NASA archivist, wrote down the story:

“So the stage was set for the global meeting when Thomas Stafford, the commander of the American spacecraft, contacted his favorite singer, and fellow Oklahoman, Conway Twitty in March 1975 to ask a favor. Stafford thought it would be a great idea to present cassettes to the Russians when the crews exchanged gifts in space and he called Twitty in Oklahoma to see if he would be willing to record them.

“At first Conway thought it was a joke. Someone suggested recording a song in Russian and when Stafford heard about it he was excited. He asked if Conway could do “Hello Darlin'”. Fortunately the artist had done a few things like that in other languages than English when he was a rock artist so he agreed.

“When I discovered it was for real, I immediately got busy…Fortunately I found Prof. Gurij Chemelev at Oklahoma University to teach me enough Russian to get by.”

“Conway Twitty tells the rest of the story in his autobiography:”So he came down to the studio and he sat on a stool right there beside me. I thought it would take maybe an hour. But it took a long time. The professor would say No, no, no, when I got the accent wrong. Having told me that the title translated into ‘Privet Radost’ in Russian, first problem was that I’d say the words softly and he would shout more no-nos at me. We went around and around, and it took him forever to understand that you don’t just holler ‘Privet Radost’ at a woman.

” ‘In Russia they do,’ he replied.

“Anyway, I finally got it all finished and sent the tape to Stafford. A short time later I was out in L.A. doing a show, and I was back in the dressing room watching Walter Cronkite. On this particular day all the astronauts and cosmonauts were up there in the same space capsule. The camera was focusing on them, and out the window you could see the earth spinning below. It was July 17, 1975.

“All of a sudden, the talking stopped and the song started playing: ‘Privet Radost.’ That song was played in Russian all around the world. I don’t know how many millions of people heard it–the only time anything like that had ever happened! It was a tremendous experience.”

Collin Fries, In Tune With Détente, with excerpts from Conway Twitty’s biography, “The Conway Twitty Story: An Authorized Biography”

Fortunately, while this memory has probably escaped all but the most ardent of space fans and historians, the song has lived on and you can hear it for yourself:

NASA’s Wakeup Calls

Perhaps the best-known examples of music in space are NASA’s wake-up calls to crews in flight, which date back to 1965, and Gemini 6. On that mission, Jack Jones sang new lyrics to the Broadway hit song “Hello Dolly” and sent them to the crew at the end of their sleep period. Before that, on Mercury and early Gemini flights, that had never been done.

Later Gemini missions featured Trini Lopez, Beethoven, Louis Armstrong, and other Broadway, standards, and classical selections. The new tradition continued through Apollo, with missions including the likes of Robert Goulet, Frank Sinatra, The Carpenters, and other popular musicians of the time.

Skylab’s Song From The Space Coast

Skylab had equally conservative musical choices, with music from The Marine Corps Band, Julie London and others. It featured an interesting choice, “My Skylab Home,” written and performed by Chuck Morley of Cocoa Beach, Florida and sent to NASA courtesy of Bill Cummings of Titusville radio station WRMF.

On the morning of August 27, 1973, Skylab 2 astronauts Al Bean & Jack Lousma were awakened by Mission Control in Houston with a song written by Chuck Morley called “Skylab Home”.

The Shuttle Era

Then, in the Shuttle era, the range of choices expanded almost exponentially: Willie Nelson, John Denver, Carole King, Elton John, The Byrds, and too many others to name punctuated the usual fare of military themes and college fight songs.

Today, on ISS, the routine continues. The choices are often quite modern: Brandi Carlile, Innocence Mission, Muse, and other alternative rock choices have been played alongside classics from The Rolling Stones and the Moody Blues. There are so many examples, but no central theme other than “wake up, time to get going” is present in the used songs.

“Wake-up music is one of my favorite parts of a mission,” says Pamela Melroy, a veteran of three shuttle missions between 2000 and 2007. “The way I was taught by my commanders, and the way I ran wake-up music on my flight as a commander, was to know in advance what crew member and what song was being played each morning.” That way, she says, there would be no question of whose family was waiting for acknowledgment on the ground.

“I set a small timer right by my head for about two minutes before, and I would gently wake up the crew member whose turn it was and make sure they were in place on the flight deck—upstairs— in time to hear the music,” Melroy explains. “I would stay up there with them, make sure they knew the name of the song if they weren’t sure, and basically be there with them to witness their moment. It’s a very fond memory from being a commander—to share those few minutes with each crew member and their loving families.”

One of the most popular wake-up selections through the years has been Louis Armstrong’s “What a Wonderful World,” which has appeared on no fewer than 11 shuttle missions, including one mission on which it was played twice for two different astronauts. (The song’s late co-composer, George David Weiss, died August 23 at the age of 89.) Armstrong’s recording was cued up at least three times for Scott Parazynski, who flew on five shuttle missions between 1994 and 2007. “‘What a Wonderful World’ was always the perfect accompaniment to the vistas from space,” Parazynski says. “My family played it for me on several missions, typically before big EVA days.” (Short for extravehicular activity, EVA is NASA-speak for a spacewalk.) “

My son Luke also dedicated the theme to Star Wars to me before the solar array repair we did on STS 120,” a 2007 shuttle mission to the International Space Station, Parazynski adds. That was probably Parazynski’s biggest day ever on the job, he says, and “it really made me smile, and put me in the perfect state of mind to go face the challenge.”

Wake-up music also offers an opportunity for lightheartedness, as was the case on STS 92, a 2000 mission to the space station. On the fifth day of the mission, ground control woke the crew with “Camelot,” from Monty Python and the Holy Grail. That moment rates as three-time shuttle flier Leroy Chiao’s favorite encounter with shuttle music. All during training the crew was quoting lines from the film, “and on the day of the first spacewalk it was played for us,” Chiao says. “It set the tone for the day, and we had a perfect spacewalk.” Like Satchmo, Monty Python has been well represented on shuttle flights—the theme to Monty Python’s Flying Circus television show 72 was played twice, and the U.K. comedy troupe’s “The Galaxy Song” was played once.

A Little Flight Music: NASA Contest for Wake-Up Songs Prompts Astronauts to Recall Tuneful Highlights, by John Matson, Scientific American, August 27, 2010

The Tragic Beauty of “Last Rendez-Vous (Ron’s Piece)”

Space Shuttle astronaut Ron McNair was a remarkable person for many, many reasons. A top student and so mechanically inclined that he earned the affectionate nickname “Gizmo” as a child, McNair was also an accomplished athlete and saxophonist: his river ran wide and deep, and after graduating from North Carolina A&T with his bachelor’s degree, he earned a PhD in Physics in 1976 from MIT.

In 1978, Dr. McNair was selected as a NASA astronaut, and he flew to space in 1984 aboard Challenger during the STS-41-B mission. NASA quickly selected McNair to fly again on a second Shuttle mission. During that mission, he planned to play a saxophone solo on live television and to record the performance to be included in celebrated artist Jean Michel Jarre’s album Rendez-Vous.

Those plans never came to fruition. McNair was one of the seven heroes who paid the price of NASA’s poorest hour when it chose to launch the OV-099 Challenger on January 26, 1986, on the infamously tragic STS-51L mission.

The piece of music that McNair was to record for has instead become a moving tribute to one of the brightest and most talented heroes America has ever produced.

Music Performed In Space

Playing music to wake up a crew or soothe their nerves is one thing, but the tradition of crews in flight creating music also goes back to the beginning. Despite their heavy workloads, imminent danger, and incredible responsibilities, astronauts and cosmonauts have found time to make music while traveling in space.

The first song to be performed in space was by Ukrainian cosmonaut Pavlo Popovych, and his selection was a Ukrainian folk song called “Watching the Sky and Thinking a Thought.” There is even a recording of the song in a video biography of Popovych:

On the American side, “Jingle Bells” was the first song to be played using a musical instrument in space. On 16 December 1965, it was played on a harmonica and bells by astronauts Wally Schirra and Thomas P. Stafford during NASA’s Gemini 6A space flight. It can be heard here:

Music has been performed in space several other times since Gemini 6, with perhaps the most famous example of it was Col. Chris Hadfield’s performance of a David Bowie song while Hadfield was aboard the International Space Station:

When asked about the version of “Space Oddity” before his death, David Bowie praised it as “possibly the most poignant version of the song ever created.” Given that the record sold millions of copies, and the Rock and Roll Hall of Fame included “Space Oddity” in their list of “The 500 Songs That Shaped Rock and Roll, that is high praise for Hadfield’s rendition.

Where Goes Humanity, Music Will Stay With Them

It is probably safe to say that music is one of the most popular and enduring forms of artistic expression and one that crosses nearly every cultural boundary.

That said, given the long history of music in spaceflight over the past sixty-three years, it is fair to say that the traditions will continue. It makes one wonder: what will be the first song performed on Mars, or even the Moon, when we reach those places? How long until professional musicians or a famous band goes to space to perform or record? Only time will tell.

Polaris Dawn has not wasted any time setting new spaceflight records.

Highest Orbit Ever: 1400.7 km

During ther first two days of their spaceflight, astronauts Sara Gillis, Jared Isaacman, Anna Menon and Scott “Kid” Poteet have set a new record for the highest crewed orbital spaceflight and 1,400 km, or 870 miles, above Earth’s surface. That broke Gemini 11 and NASA Astronaut Pete Conrad’s 1,373 km or 853 miles record set in 1966.

Others, left to right, are Kathryn D. Sullivan, Bruce McCandless II and Steven A. Hawley, all mission specialists. Photo credit: NASA

At the same time, Gillis and Menon became the highest-flying female astronauts, a notable achievement in its own right. The previous record holder was NASA Astronaut Kathryn Sullivan, who reached an altitude of 621 km, or 386 miles, aboard the Space Shuttle orbiter Discovery on the STS-31 mission that deployed the Hubble Space Telescope in 1990.

Most Humans In Orbit: 19

Polaris Dawn’s astronauts are also part of the list of most people in orbit in human history, which was set today with the launch of Soyuz MS-26 carrying two Russian cosmonauts and NASA Astronaut Don Pettit to the International Space Station. That makes nineteen people in orbit, breaking the previous record of 17 set in 2023:

  • Soyuz MS-26: Don Pettit, Alexey Ovchinin, Ivan Vagner, aboard ISS
  • Starliner CFT / Crew 9: Butch Wilmore, Suni Williams, aboard ISS
  • Crew 8: Matthew Dominick, Michael Barratt, Jeanette Epps, Alexander Grebenkin, aboard ISS
  • Soyuz MS-25: Oleg Kononenko, Tracy Dyson, Nikolai Chub, aboard ISS
  • Shenzou 18: Li Guangsu, Li Cong, Ye Guangfu, aboard Tiangong
  • Polaris Dawn: Sarah Gillis, Jared Isaacman, Anna Menon, Scott Poteet, in flight

Late in the afternoon, the crew of Polaris Dawn released this update:

Polaris Dawn’s New World Records, Considered:

The two records Polaris Dawn has broken are both long-standing, and both new records are reminiscent of the early days in aviation when new records were set with regularity.

People know Charles Lindbergh and Amelia Earhart for their first trans-Atlantic flights. They are also probably familiar with some of Howard Hughes’ aviation achievements; he not only built and designed record-breaking aircraft but often flew them himself.

There are other less famous names who have set aviation records. You may not know of pioneers like Rudolph W. “Shorty” Schroeder, who reached a world-record height of 33,114 feet in 1920, or Jacqueline Cochran, the first woman to fly faster than the speed of sound, among many other records she set.

Jacqueline Cochran
Via: National Air and Space Museum, Smithsonian Institution

All those people — and many others — were pioneering trailblazers who raised the bar, and now the Polaris Dawn crew has joined that small, elite club.

Their records will eventually be broken — for example, Christina Koch will achieve the farthest a woman has traveled from the Earth when she orbits the moon aboard Artemis II, and some crew will eventually orbit higher than 1,400 km above the Earth surface. That will be progress, and it will not diminish the progress Polaris Dawn has made.

Records are made to be broken and that’s exactly what Polaris Dawn is doing while it’s in space.

SpaceCoastLaunchCalendar.com will have a livestream of the launch if you’re not able to watch the launch in person: Livestream

SpaceX will have a livestream of the launch on their website: Polaris Dawn. This will also be available on the X platform. Coverage will start about 3.5 hours prior to liftoff.

Spaceflight Now will have coverage of the launch starting about one hour before liftoff on Youtube: link

For official updates regarding launch timesSpaceX.com is the best source of information. Starlink launch times change from time to time, and the company generally updates their website within minutes of the decision to change the launch time. This is very handy if none of the streaming options on YouTube have started their broadcasts.

Remember that there is a delay between a launch stream and the actual countdown clock. That is simply because of physics: it takes time for the signal to travel from the launch site, through the Internet, and back down to your phone, resulting in a five to fifteen-second delay.

Next Space Flight an app for iOS and Android phones, has a real-time countdown clock that is accurate to a second, give or take. The app is free. Search the App Store or Google Play. They are also on the web: nextspaceflight.com.

Launch Viewing: In Person

Given that this is a launch from Kennedy Space Center with no booster return to the Cape, Max Brewer Bridge and the northern Tistusville parks on Washington Avenue (US1) are your best bets: Space View Park, Rotary Riverview Park and others.

Merritt Island National Wildlife Refuge and Cape Canaveral National Seashore will be closed for the evening, but if the launch pushes past 6AM EDT, those areas should be open.

SpaceX has called off the Polaris Dawn launch of Falcon 9 until at least Friday, August 29th. The company announced shortly after 10 PM EDT that it was standing down for the night, and stated on its website that its next attempt would be no earlier than the end of the week:

Those areas would be of vital importance in the unlikely event of an in-flight abort that forced Crew Dragon and the Polaris Dawn crew to land downrange in the seas off of the Florida coast. With unacceptable conditions there, the launch was scrubbed roughly 5.5 hours before L-0.

The launch vehicle and crew remain healthy and safe, and a new launch date will likely be announced soon.

Repairs on Helium Quick-Disconnect Completed Earlier Tuesday

SpaceX completed repairs on the faulty quick-disconnect Helium supply line earlier in the day with alacrity, as repairs were completed by early afternoon. Shortly afterward, around 2 PM, Falcon was raised to a standing launch condition. Unfortunately, weather conditions offshore in the abort zone necessitated a two-day stand-down hours later.

A familiar face to many space supporters, Sarah Gillis works for SpaceX as the Lead Space Operations engineer for the company, and she is often seen in documentaries and broadcasts of SpaceX’s crewed launch activities. She is often seen the Netflix documentary “Countdown: Inspiration4 Mission to Space,” where she she helped train the crew for their upcoming flight and also during the activities in space.

From Boulder Colorado, Ms. Gillis says that, “Growing up in a family of artists and musicians, I can’t say I grew up dreaming of being an engineer (or even knowing what engineering was). Rather, I fell into it when I discovered there was a profession entirely dedicated to creative problem solving, and have been hooked ever since.”

Gillis holds a degree in Aerospace Engineering from the University of Colorado. This will be her first space flight.

From Houston, Texas, Anna Menon also works for SpaceX as the Lead Space Operations Engineer. In her role, she manages the development of crew operations and serves in mission control as both a Mission Director and crew communicator.

She has led the implementation of Dragon’s crew capabilities, helped create the crew communicator operator role, and developed critical operational responses to vehicle emergencies such as a fire or cabin depressurization. Anna served in mission control during multiple Dragon missions, such as Demo-2, Crew-1, CRS-22, CRS-23, Crew-3, Crew-4, and Axiom-1.

Menon is a NASA veteran, woking seven years at the agency as a biomedical flight controller for the International Space Station.

She holds a bachelor’s degree in Mathematics and also Spanish from TCU (Texas Christian University) as well as a master’s degree in Biomedical Engineering from Duke University.

This will also be her first spaceflight.


Polaris Dawn is scheduled to launch Tuesday, August 27th. SpaceX is targeting Tuesday, August 27 at 3:38 a.m. ET for Falcon 9’s launch from Launch Complex 39A SpaceX adds that there are two additional launch opportunities within the four-hour window at 5:23 a.m. ET and 7:09 a.m. ET. If needed, backup opportunities are available on Wednesday, August 28 at the same times.

Polaris Dawn, the initial flight of a planned series of three private spaceflights led by American entrepreneur and private astronaut Jared Isaacman, has been delayed according to an announcement from the program today. “We are now targeting no earlier than summer 2024 for launch of Polaris Dawn, the first of the Polaris Program’s three human spaceflights,” they said in a post on the X platform.

Flying aboard a SpaceX Falcon 9 and a Crew Dragon capsule from Kennedy Space Center’s LC-39A, the five-day Polaris Dawn mission will represent several firsts for private spaceflight: the first time an EVA is undertaken from a private spacecraft in orbit, and at a planned altitude of at least 700 km (434 miles) it will be well above the 400 km (~250 mile) orbit of ISS when that spacewalk happens.

They are also planning a 1,400 km (~870 mile) apogee during the flight, according to Polaris Program. Currently, the record for altitude for a crew in Earth orbit is 1,369.0 km, (739.2 nautical miles.) Should Polaris Dawn reach 1,400 km, it will be the highest crewed orbital flight in human history, and certainly the highest in over fifty years.

Polaris Dawn Science Plans

Aside from the groundbreaking EVA, Polaris Dawn will also be “the first crew to test Starlink laser-based communications in space.” They will also perform experiments:

  • “Using ultrasound to monitor, detect, and quantify venous gas emboli (VGE), contributing to studies on human prevalence to decompression sickness;
  • “Gathering data on the radiation environment to better understand how space radiation affects human biological systems;
  • “Providing biological samples towards multi-omics analyses for a long-term Biobank; and
  • “Research related to Spaceflight Associated Neuro-Ocular Syndrome (SANS), which is a key risk to human health in long-duration spaceflight.”

There are other experiments planned for Polaris Dawn. More information about the Polaris Dawn mission is at the program’s website.

After the Polaris Dawn flight, the Polaris Program plans one additional flight on a Falcon 9 / Crew Dragon, and a final flight being planned to be completed using a SpaceX Starship, the company’s new rocket under development in south Texas. The third flight is also slated to be the first crewed flight of Starship according to the Polaris Program website. Launch timelines for those missions have not yet been publicly disclosed.

More Development Time Needed

According to the Polaris Program, “The additional time continues to provide necessary developmental time to ensure both the completion of these mission goals and a safe launch and return of Dragon and the crew.” They did not give specifics about which aspects of the mission require further time, but did add that the crew is already training at SpaceX headquarters in Hawthorne, California and also that additional time gives the crew additional time to raise funds for the St. Jude Children’s Research Hospital.

About St. Jude

St. Jude Children’s Research Hospital is located in Memphis, Tennessee, and according to their website, they “Advance cures, and means of prevention, for pediatric catastrophic diseases through research and treatment. Consistent with the vision of our founder Danny Thomas, no child is denied treatment based on race, religion or a family’s ability to pay.”

There are few causes with greater impact than helping families whose children are undergoing treatment for severe, life-threatening illnesses. Interested people can donate to St. Jude through the Polaris Dawn website.
