NASA is all about solving challenges, and the goal of having a prolonged presence in space, or a colony on Mars or some other world, is full of challenges, including the necessity of growing food. Scientists at Kennedy Advanced Life Support Research are working on the Prototype Lunar/Mars Greenhouse Project to try and meet that challenge.
The Prototype Lunar/Mars Greenhouse Project (PLMGP) is all about growing vegetables for astronauts during extended stays on the Moon, on Mars, or anywhere they can’t be resupplied from Earth. Beyond growing food, the Project aims to understand how food-growing systems can also be a part of life-support systems.
“The approach uses plants to scrub carbon dioxide, while providing food and oxygen.” – Dr. Ray Wheeler
“We’re working with a team of scientists, engineers and small businesses at the University of Arizona to develop a closed-loop system. The approach uses plants to scrub carbon dioxide, while providing food and oxygen,” said Dr. Ray Wheeler, lead scientist in Kennedy Advanced Life Support Research.
The prototype itself is an inflatable, deployable system that researchers call a bioregenerative life support system. As crops are grown, the system recycles, water, recycles waste, and revitalizes the air.
The system is hydroponic, so no soil is needed. Water that is either brought along on missions or gathered in situ—on the Moon or at Mars for example—is enriched with nutrient salts, and flows continuously through plant root systems. Air in the system is recycled too. Astronauts exhale carbon dioxide, which plants absorb. Through photosynthesis, the plants produce oxygen for the astronauts.

“We’re mimicking what the plants would have if they were on Earth and make use of these processes for life support,” said Dr. Gene Giacomelli, director of the Controlled Environment Agriculture Center at the University of Arizona. “The entire system of the lunar greenhouse does represent, in a small way, the biological systems that are here on Earth.”
“The entire system of the lunar greenhouse does represent, in a small way, the biological systems that are here on Earth.” – Dr. Gene Giacomelli
A key part of a system like this is knowing what astronauts will have to bring with them, and what resources they can find at their destination. This includes which type of plants and seeds will be needed, as well as how much water might be available once astronauts reach their destination. Methods of extracting water on Mars or the Moon are also being researched and developed.
Even if the necessary water can be found in situ on Mars and the Moon, that hardly means those are easy places to grow food. Astronauts have to be protected from radiation, and so will crops. These greenhouse chambers would have to buried underground, which means specialized lighting systems are also required.
“We’ve been successful in using electric LED (light emitting diode) lighting to grow plants,” Dr. Wheeler said. “We also have tested hybrids using both natural and artificial lighting.” Solar light could be captured with light concentrators that track the sun and then convey the light to the chamber using fiber optic bundles.
These systems are not NASA’s first experience at growing crops in space. Experiments aboard the International Space Station (ISS) have been an important part of the research into crop production in non-terrestrial environments. The Veggie Plant Growth System was NASA’s first attempt, and astronauts successfully harvested lettuce from that system.

Earth has well-established systems for sustaining life, and this project is all about taking some of that to distant destinations in space.
“I think it’s interesting to consider that we’re taking our terrestrial companions with us,” Wheeler said. “While there may be ways to engineer around it in terms of stowage and resupply, it wouldn’t be as sustainable. The greenhouses provide a more autonomous approach to long-term exploration on the moon, Mars and beyond.”

Furthermore Whitson received a long distance phone call of exuberant congratulations from President Donald Trump, First Daughter Ivanka Trump, and fellow astronaut Kate Rubins direct from the Oval Office in the White House to celebrate the momentous occasion.
“This is a very special day in the glorious history of American spaceflight!” said President Trump during the live phone call to the ISS broadcast on NASA TV.
As of today, Whitson exceeded 534 cumulative days in space by an American astronaut, breaking the record held by NASA astronaut Jeff Williams.
“Today Commander Whitson you have broken the record for the most total time spent in space by an American astronaut. 534 days and counting,” elaborated President Trump.
“That’s an incredible record to break. And on behalf of the nation and frankly the world I would like to congratulate you. That is really something!”
“You’re an incredible inspiration to us all.”
Trump noted that thousands of school students were listening in to the live broadcast which also served to promote students to study STEM subjects.
“Peggy is a phenomenal role model for young women, and all Americans, who are exploring or participating in STEM education programs and careers,” said President Trump.
“As I have said many times before, only by enlisting the full potential of women in our society will we be truly able to make America great again. When I signed the INSPIRE Women Act in February, I did so to ensure more women have access to STEM education and careers, and to ensure America continues to benefit from the contributions of trailblazers like Peggy.”
How does it feel to break the endurance record? Trump asked Whitson.
“It’s actually a huge honor to break a record like this, but it’s an honor for me basically to be representing all the folks at NASA who make this spaceflight possible and who make me setting this record feasible,” Whitson replied from orbit to Trump.
“And so it’s a very exciting time to be at NASA. We are all very much looking forward, as directed by your new NASA bill — we’re excited about the missions to Mars in the 2030s. And so we actually, physically, have hardware on the ground that’s being built for the SLS rocket that’s going to take us there.”
“It’s a very exciting time, and I’m so proud of the team.”
“We have over 200 investigations ongoing onboard the space station, and I just think that’s a phenomenal part of the day.”
NASA astronaut Jack Fischer is also serving aboard the station on his rookie flight and also took part in the phone call with President Trump.
Whitson is currently serving as Space Station Commander of Expedition 51. She most recently launched to the ISS on Nov 17, 2016 aboard a Russian Soyuz capsule from the Baikonur Cosmodrome in Kazakhstan, as part of a three person crew.
At the time of her Soyuz launch she had accumulated 377 total days in space.
She holds several other prestigious records as well. Whitson is the first woman to serve twice as space station commander.
Indeed in 2008 Whitson became the first woman ever to command the space station during her prior stay on Expedition 16 a decade ago. Her second stint as station commander began earlier this month on April 9.
Whitson also holds the record for most spacewalks by a female astronaut. Altogether she has accumulated 53 hours and 23 minutes of EVA time over eight spacewalks.
Overall, Expedition 51 involved her third long duration stay aboard the massive orbiting laboratory complex.

“This is an inspirational record Peggy is setting today, and she would be the first to tell you this is a record that’s absolutely made to be broken as we advance our knowledge and existence as both Americans and humans,” said NASA acting Administrator Robert Lightfoot, in a statement.
“The cutting-edge research and technology demonstrations on the International Space Station will help us go farther into our solar system and stay there longer, as we explore the mysteries of deep space first-hand. Congratulation to Peggy, and thank you for inspiring not only women, but all Americans to pursue STEM careers and become leaders.”
When she returns to Earth in September she will have accumulated some 666 days in space.

Trump made note of the science and commercial industrial work being carried out aboard the station.
“Many American entrepreneurs are racing into space. I have many friends that are so excited about space. They want to get involved in space from the standpoint of entrepreneurship and business,” said President Trump.
“And I’m sure that every student watching wants to know, what is next for Americans in space.”
Indeed the private SS John Glenn Cygnus cargo freighter just arrived at the ISS on Saturday, April 22, carrying nearly 4 tons or science experiments, hardware, parts and provisions.
Whitson was one of two ISS astronauts involved in capturing Cygnus with the Canadian built robotic arm for attachment to the stations Unity node.
Trump also mentioned his strong support for sending humans on a mission to Mars in the 2030s and for NASA’s development of the SLS heavy lift rocket and Orion deep space capsule.
“I’m very proud that I just signed a bill committing NASA to the aim of sending America astronauts to Mars. So we’ll do that. I think we’ll do it a lot sooner than we’re even thinking.”
“Well, we want to try and do it during my first term or, at worst, during my second term. So we’ll have to speed that up a little bit, okay?”

Four days after liftoff the SS John Glenn finally arrived at the station as planned Saturday morning April 22 following a carefully choreographed series of thruster maneuvers this past week.
The private Cygnus resupply vessel is carrying nearly four tons of science and supplies crammed inside for the five person multinational Expedition 51 crew.
After reaching the vicinity of the space station overnight Saturday, Cygnus was successfully captured by astronaut crew members Thomas Pesquet of ESA (European Space Agency) and Expedition 51 Station Commander Peggy Whitson of NASA at 6:05 a.m. EDT using the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm.
The SS John Glenn Cygnus vehicle counts as Orbital ATK’s seventh cargo delivery flight to the station.
The vehicle is also known alternatively as the Cygnus OA-7 or CRS-7 mission.
Cygnus OA-7 is loaded with 3459 kg (7626 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.

After reaching the vicinity of the space station overnight Saturday, the commercial Cygnus cargo ship was successfully captured by astronaut crew members Thomas Pesquet of ESA (European Space Agency) and Expedition 51 Station Commander Peggy Whitson of NASA at 6:05 a.m. EDT using the stations Canardarm2.
Working at robotic work consoles inside the domed Cupola module, Pesquet and Whitson deftly maneuvered the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm to reach out and flawlessly snare the Cygnus CRS-7 spacecraft at 6:05 a.m. EST at the short and tiny grappling pin located at the base of the vessel.

Cygnus and the station were soaring some 250 miles (400 km) over Germany as they were joined at Canada’s high tech arm in a perfect demonstration of the peaceful scientific purpose of the massive laboratory complex.
The private supply ship was moved and bolted into place a few hours later at 8:19 a.m. EDT to physically berth and join the station at the Unity module.
Thus begins a three month long sentimental journey ‘bridging history’ to the dawn of America’s human spaceflight with the cylindrically shaped ship named in tribute to John Glenn – the first American to orbit Earth way back in 1962.
The SS John Glenn is a private Cygnus spacecraft manufactured by Orbital ATK under the commercial resupply services (CRS) contact with NASA whose purpose is to deliver many thousands of pounds of cargo and research supplies to the space station to enable the scientific research for which it was built.
Cygnus arrived at the station via a carefully choreographed series on thruster maneuvers after almost four days in orbit following liftoff earlier this week.

“Over the pin. Trigger initiated and snares closed,” radioed Pesquat in the final moments of approach as he carefully and ever so slowly moved the arm towards Cygnus this morning.
“Capture confirmed right on time at 6:05 a.m,” replied Houston Mission Control.
“We have a good capture, and are go for safing,” reported Station Commander Whitson.
“The crew of Expedition 51 would like to congratulate all the teams at NASA, Orbital ATK and the contractors for a flawless cargo-delivery mission,” Pesquat elaborated. “We are very proud to welcome onboard the S.S. John Glenn.”
“The more than three tons of pressurized cargo in the Cygnus spacecraft will be put to good use to continue our mission of research, exploration and discovery. Achievements like this, fruit of the hard work by space agencies and private companies and the international cooperation across the world, are what truly makes the ISS such a special endeavor at the service of all mankind.”
“Station, Houston, well said,” replied Mission Control.
After the astronauts finished their work in orbit, mission controllers in Houston took over and commanded the arm to move Cygnus to the Earth facing port on Node 1 where it was remotely bolted in place with 16 hooks and latches and hard mated to the Unity module.

The mission is named the ‘S.S. John Glenn’ in tribute to legendary NASA astronaut John Glenn – the first American to orbit Earth back in February 1962.
Glenn was one of the original Mercury Seven astronauts selected by NASA. At age 77 he later flew a second mission to space aboard Space Shuttle Discovery- further cementing his status as a true American hero.
Glenn passed away in December 2016 at age 95. He also served four terms as a U.S. Senator from Ohio.

Cygnus OA-7 is loaded with 3459 kg (7626 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.
Science plays a big role in this mission named in tribute to John Glenn. Over one third of the payload loaded aboard Cygnus involves science.
“The new experiments will include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and growth of fresh food in space,” according to NASA.
The astronauts will grow food in space, including Arabidopsis and dwarf wheat, in an experiment that could lead to providing nutrition to astronauts on a deep space journey to Mars.
“Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments. Cygnus also is carrying 38 CubeSats, including many built by university students from around the world as part of the QB50 program. The CubeSats are scheduled to deploy from either the spacecraft or space station in the coming months.”
Also aboard is the ‘Genes in Space-2’ experiment. A high school student experiment from Julian Rubinfien of Stuyvescent High School, New York City, to examine accelerated aging during space travel. This first experiment will test if telomere-like DNA can be amplified in space with a small box sized experiment that will be activated by station astronauts.
The Saffire III payload experiment will follow up on earlier missions to study the development and spread of fire and flames in the microgravity environment of space. The yard long experiment is located in the back of the Cygnus vehicle. It will be activated after Cygnus departs the station roughly 80 days after berthing. It will take a few hours to collect the data for transmission to Earth.

This image taken by the Mars Reconnaissance Orbiter's HiRise camera shows the bright landing platform left behind by NASA's Mars Exploration Rover Opportunity when it landed in 2004.

NASA’s eagle-eyed Mars Reconnaissance Orbiter (MRO) has captured orbital images of Opportunity’s Hole-In-One landing site, smack dab in the middle of Eagle Crater on the surface of Mars.
Opportunity arrived at Mars on January 25th, 2005. It’s landing was slowed by parachute, and cushioned by airbags. Once it hit the surface, it bounced its way into “Eagle Crater“, a feature a mere 22 meters across. Not a bad shot!
This is the first color image that the High Resolution Imaging Science Experiment (HiRise) has captured of Opportunity’s landing site. It shows the remarkable landing site inside the crater, where the landing pad was left behind after Opportunity rolled off of it and got going. It also shows the rover’s parachute and backshell.
It’s amazing that, given the relatively smooth surface in Opportunity’s landing area, the rover came to rest inside a small crater. When Opportunity “woke up” at its landing site, its first images were of the inside of Eagle Crater. This was the first look we ever got at the sedimentary rocks on Mars, taken by the rover’s navigation camera.

After leaving Eagle Crater, Opportunity took a look back and captured a panoramic image. Plainly visible is the rover’s landing pad, the exposed sedimentary rock, and the rover’s tracks in the Martian soil.
This panorama image, called “Lion King” was assembled from 558 images totalling over 75 megabytes. The rock outcrop, the landing pad, and the rover’s tracks are all clearly visible. Image: NASA/JPL/Cornell
MRO arrived at Mars a couple years later, and by that time Opportunity had already left its landing site and made its way south to the much larger Victoria Crater.
When the Mars Reconnaissance Orbiter arrived at Mars, 2 years after Opportunity touched down there, Opportunity had left Eagle Crater and travelled the 6 km to Victoria Crater.

Opportunity is still chugging along, doing valuable work. And so is the MRO and its HiRise instrument. At this point, Opportunity has to be considered one of the most successful scientific undertakings ever.

You’d have to be an intrepid explorer to investigate something named ‘Cape Tribulation’. Opportunity, NASA’s long-lived rover on Mars’ surface, has been just that. But Opportunity is now leaving Cape Tribulation behind, after being in that area since late 2014, or for about 30 months.
Cape Tribulation is the name given to a segment of crater rim at Endeavour Crater, where Opportunity has been for over 5 1/2 years. During that time, Opportunity reached some important milestones. While there, it surpassed 26 miles in distance travelled, the length of a marathon race. It also reached its highest elevation yet, and in ‘Marathon Valley’, it investigated clay outcrops seen from orbit. Opportunity also had some struggles there, when its flash memory stopped working, meaning all data had to be transmitted every day, or lost.

Before reaching Cape Tribulation 30 months ago, Opportunity investigated other parts of Endeavour Crater called “Cape York,” “Solander Point” and “Murray Ridge.”

The rover’s next destination is Perseverance Valley, where it will investigate how it was carved out billions of years ago: by water, by wind, or perhaps flowing material lubricated by water. Before leaving Cape Tribulation, Opportunity captured the panoramic image of Rochefort Ridge, a section of the Endeavour Crater rim marked by grooves on its side.”The degree of erosion at Rocheport is fascinating,” said Opportunity Deputy Principal Investigator Ray Arvidson, of Washington University in St. Louis. “Grooves run perpendicular to the crest line. They may have been carved by water or ice or wind. We want to see as many features like this on the way to Perseverance Valley as we can, for comparison with what we find there.”
Endeavour crater is about 22km in diameter, and Perseverance Valley is about 2 football fields long. The goal at Endeavour is to investigate its segmented rim, where the oldest rocks ever investigated on Mars are exposed. Since the beginning of April, Opportunity has travelled about 98 meters, to a point where Cape Tribulation meets the plain around the crater.
“From the Cape Tribulation departure point, we’ll make a beeline to the head of Perseverance Valley…” – Opportunity Deputy Principal Investigator Ray Arvidson
“From the Cape Tribulation departure point, we’ll make a beeline to the head of Perseverance Valley, then turn left and drive down the full length of the valley, if we can,” Arvidson said. “It’s what you would do if you were an astronaut arriving at a feature like this: Start at the top, looking at the source material, then proceed down the valley, looking at deposits along the way and at the bottom.”
It’s the nature of those deposits that can give vital clues to how Perseverance Valley was formed. Arvidson said, “If it was a debris flow, initiated by a little water, with lots of rocks moving downhill, it should be a jumbled mess. If it was a river cutting a channel, we may see gravel bars, crossbedding, and what’s called a ‘fining upward’ pattern of sediments, with coarsest rocks at the bottom.”
Opportunity, and its sister rover Spirit, arrived at Mars in 2004, with a planned mission length of 90 days. Opportunity has surpassed that by over 12 years, and continues to perform extremely well in the Martian environment.
The appearing and disappearing feature observed in Titan's Lakes was dubbed "Magic Island". Image: NASA/JPL-Caltech/ASI/Cornell
Saturn’s largest Moon, Titan, is the only other world in our Solar System that has stable liquid on its surface. That alone, and the fact that the liquid is composed of methane, ethane, and nitrogen, makes it an object of fascination. The bright spot features that Cassini observed in the methane seas that dot the polar regions only deepen the fascination.
A new paper published in Nature Astronomy digs deeper into a phenomenon in Titan’s seas that has been puzzling scientists. In 2013, Cassini noticed a feature that wasn’t there on previous fly-bys of the same region. In subsequent images, the feature had disappeared again. What could it be?
One explanation is that the feature could be a disappearing island, rising and falling in the liquid. This idea took hold, but was only an initial guess. Adding to the mystery was the doubling in size of these potential islands. Others speculated that they could be waves, the first waves observed anywhere other than on Earth. Binding all of these together was the idea that the appearance and disappearance could be caused by seasonal changes on the moon.

Now, scientists at NASA’s Jet Propulsion Laboratory (JPL) think they know what’s behind these so-called ‘disappearing islands,’ and it seems like they are related to seasonal changes.
The study was led by Michael Malaska of JPL. The researchers simulated the frigid conditions on Titan, where the temperature is -179.2 Celsius. At that temperature, some interesting things happen to the nitrogen in Titan’s atmosphere.
On Titan, it rains. But the rain is composed of extremely cold methane. As that methane falls to the surface, it absorbs significant amounts of nitrogen from the atmosphere. The rain hits Titan’s surface and collects in the lakes on the moon’s polar regions.
The researchers manipulated the conditions in their experiments to mirror the changes that occur on Titan. They changed the temperature, the pressure, and the methane/ethane composition. As they did so, they found that nitrogen bubbled out of solution.
“Our experiments showed that when methane-rich liquids mix with ethane-rich ones — for example from a heavy rain, or when runoff from a methane river mixes into an ethane-rich lake — the nitrogen is less able to stay in solution,” said Michael Malaska of JPL. This release of nitrogen is called exsolution. It can occur when the seasons change on Titan, and the seas of methane and ethane experience a slight warming.
“Thanks to this work on nitrogen’s solubility, we’re now confident that bubbles could indeed form in the seas, and in fact may be more abundant than we’d expected,” said Jason Hofgartner of JPL, a co-author of the study who also works on Cassini’s radar team. These nitrogen bubbles would be very reflective, which explains why Cassini was able to see them.

The seas on Titan may be what’s called a prebiotic environment, where chemical conditions are hospitable to the appearance of life. Some think that the seas may already be home to life, though there’s no evidence of this, and Cassini wasn’t equipped to investigate that premise. Some experiments have shown that an atmosphere like Titan’s could generate complex molecules, and even the building blocks of life.
NASA and others have talked about different ways to explore Titan, including balloons, a drone, splashdown landers, and even a submarine. The submarine idea even received a NASA grant in 2015, to develop the idea further.
So, mystery solved, probably. Titan’s bright spots are neither islands nor waves, but bubbles.
Cassini’s mission will end soon, and it’ll be quite some time before Titan can be investigated further. The question of whether Titan’s seas are hospitable to the formation of life, or whether there may already be life there, will have to wait. What role the nitrogen bubbles play in Titan’s life question will also have to wait.

KENNEDY SPACE CENTER, FL – A new Russian/American duo has arrived at the International Space Station this morning, April 20, after a six-hour flight following their successful launch aboard a Russian Soyuz capsule on a fast track trajectory to the orbiting outpost.
The two person international crew comprising NASA astronaut Jack Fischer and cosmonaut Fyodor Yurchikhin of the Russian space agency Roscosmos launched aboard a Russian Soyuz MS-04 spacecraft from the Baikonur Cosmodrome in Kazakhstan at 3:13 a.m. (1:13 p.m. Baikonur time).
After orbiting the Earth just four times on a planned accelerated trajectory they reached the station six hours later and safely docked at the station at 9:18 a.m. EDT.
“We have contact and capture confirmed at the space station at 9:18 am EDT,” said the NASA Houston mission control commentator.
The station and Soyuz vehicles were flying some 250 mi (400 km) over the northern Atlantic at the time of docking.
The dynamic duo of Yurchikhin and Fischer join three Expedition 51 crew members already onboard – Expedition 51 Commander Peggy Whitson of NASA and Flight Engineers Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency).
Thus the overall station crew complement of astronauts and cosmonauts increases to five – from the US, Russia and France – representing their respective space agencies and countries.
Jack Fisher is a rookie space flyer whereas Yurchikhin is an accomplished veteran on this his 5th mission to orbit.

Prior to docking the crew accomplished an approximately 10 min flyaround inside the Soyuz shortly before sunrise and beautyfully backdropped by earth towards the end at a distance of roughly several hundred meters away.
All Soyuz systems performed as planned for what was an entirely automated rendezvous and docking using the Russian KURS docking system. The crew could have intervened if needed.
The new pair of Expedition 51 crew members will spend about four and a half months aboard the station during their increment.
They will be very busy conducting approximately 250 science investigations in fields such as biology, Earth science, human research, physical sciences and technology development.
And there will be no time to rest! Because this week’s just launched unpiloted ‘SS John Glenn’ Cygnus resupply ship is eagerly awaiting its chance to join the station and deliver nearly 4 tons of science experiment, gear and crew provisions to stock the station and further enhance its research output.
Orbital ATK’s seventh Cygnus cargo delivery flight to the station – dubbed OA-7 or CRS-7 – launched at 11:11 a.m. EDT Tuesday, April 18 atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

The SS John Glenn is expected to arrive at the station early Saturday morning on April 22.
Expedition 51 astronauts Thomas Pesquet of ESA and Peggy Whitson of NASA will use the space station’s Canadian-built robotic arm to grapple Cygnus, about 6:05 a.m. Saturday.
They will use the arm to maneuver and berth the unmanned vehicle to the Node-1 Earth-facing nadir port on the Unity module.
“Investigations arriving will include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and growth of fresh food in space,” says NASA.
“Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments. Cygnus also is carrying 38 CubeSats, including many built by university students from around the world, as part of the QB50 program. The CubeSats are scheduled to deploy from either the spacecraft or space station in the coming months.”
Cygnus will remain at the space station for about 85 days until July before its destructive reentry into Earth’s atmosphere, disposing of several thousand pounds of trash.

To some, art and science are opposed to one another. Art is aesthetics, expression, and intuition, while science is all cold, hard, rational thought. But that’s a simplistic understanding. They’re both quintessential human endeavours, and they’re both part of the human spirit.
Some at NASA have always understood this, and there’s actually an interesting, collaborative history between NASA and the art world, that reaches back several decades. Not the kind of art that you see hanging in elite galleries in the world’s large cities, but the kind of art that documents achievements in space exploration, and that helps us envision what our future could be.

Back in 1962, when NASA was 4 years old, NASA administrator James Webb put the wheels in motion for a collaboration between NASA and American artists. Artist Bruce Stevenson had been commissioned to produce a portrait of Alan Shepard. Shepard, of course, was the first American in space. He piloted the first Project Mercury flight, MR-3, in 1961. When Webb saw it, he got a bright idea.
When Stevenson brought is portrait of Shepard to NASA headquarters, James Webb thought that Stevenson wanted to paint portraits of all seven Mercury astronauts. But Webb thought a group portrait would be even better. The group portrait was never produced, but it got Webb thinking. In a memo, he said “…we should consider in a deliberate way just what NASA should do in the field of fine arts to commemorate the …historic events” of the American space program.
That set in motion a framework that exists to this day. Beyond just portraits, Webb wanted artists to produce paintings that would convey the excitement around the entire endeavour of space flight, and what the deeper meaning behind it might be. He wanted artists to capture all of the excitement around the preparation and countdown for launches, and activities in space.

That’s when the NASA collaboration with artists began. A young artist named James Dean was assigned to the program, and he took a page out of the Air Force’s book, which established its own art program in 1954.
There’s a whole cast of characters involved, each one contributing to the success of the program. One such person was John Walker, Director of the National Gallery. He was enthusiastic, saying in a talk in 1965 that “the present space exploration effort by the United States will probably rank among the more important events in the history of mankind.” History has certainly proven those words to be true.
This Norman Rockwell painting is from 1965, and shows astronauts Gus Grissom and John Young suiting up for the first Gemini flight in March, 1965. NASA loaned Rockwell a spacesuit for the painting. Image: Norman Rockwell, NASA Art Program
Walker went on to say that it was the artists’ job “…not only to record the physical appearance of the strange new world which space technology is creating, but to edit, select and probe for the inner meaning and emotional impact of events which may change the destiny of our race.”
And that’s what they did. Artists like Norman Rockwell, Andy Warhol, Peter Hurd, Annie Liebowitz, Robert Rauschenberg, and others, all took part in the program.

In the 1970’s, thinkers like Gerard K. O’Neill began to formulate ideas of what human colonies in space might look like. NASA held a series of conferences where these ideas were shared and explored. Artists Rick Guidice and Don Davis created many paintings and illustrations of what colony designs like Bernal Spheres, Double Cylinders, and Toroidal Colonies might look like.

NASA continues to work with artists, though the nature of the relationship has changed over the decades. Artists are often used to flesh out new discoveries when images are not available. Cassini’s so-called Grand Finale, when it will orbit between Saturn and its rings 22 times before crashing into the planet, was conceptualized by an unnamed artist.

The recent discovery of the exoplanets in the TRAPPIST-1 system was huge news. It still is. But TRAPPIST-1 is over 40 light years away, and NASA relied on artists to bring the discovery to life. This illustration was widely used to help us understand what planets orbiting the TRAPPIST-1 Red Dwarf might look like.

NASA now has quite a history of relying on art to convey what words can’t do. Space colonies, distant solar systems, and spacecraft ending their missions on other worlds, have all relied on the work of artists. But if I had to choose a favorite, it would probably be the 1981 water color by artist Henry Casselli. It makes you wonder what it’s like for an individual to take part in these species-defining endeavours. Just one person, sitting, contemplating, and preparing.

KENNEDY SPACE CENTER, FL – The ‘SS John Glenn’ cargo freighter stands proudly poised for launch at pad 41 from the Florida Space Coast on Tuesday April 18, loaded with a stash of nearly 4 tons of science investigations and essential supplies atop a United Launch Alliance Atlas V rocket destined for the multinational crew aboard the International Space Station (ISS).
The lunchtime liftoff of the ‘SS John Glenn’ Cygnus resupply spacecraft manufactured by NASA commercial cargo provider Orbital ATK is slated for 11:11 a.m. EDT Tuesday, April 18 from Space Launch Complex 41 on Cape Canaveral Air Force Station, FL.
The US cargo ships provided by NASA suppliers Orbital ATK and SpaceX every few months act as NASA’s essential railroad to space. And they are vital to operating the station with a steady stream of new research experiments as well as essential hardware, spare parts, crew supplies, computer, maintenance and spacewalking equipment as well food, water, clothing, provisions and much more.
The launch window lasts 30 minutes and runs from 11:11-11:41 a.m. EDT April 18.
Excited spectators are gathering from near and far and Tuesday’s weather outlook is spectacular so far.

Blastoff of the S.S. John Glenn on the OA-7 or CRS-7 flight counts as Orbital ATK’s seventh contracted commercial resupply services mission to the ISS for NASA.
The ‘S.S. John Glenn’ is named in honor of legendary NASA astronaut John Glenn – the first American to orbit Earth back in February 1962.
If you can’t attend in person, there are a few options to watch online.
NASA’s Atlas V/Cygnus CRS-7 launch coverage will be broadcast on NASA TV and the NASA launch blog beginning at 10 AM, Tuesday morning.
A ULA webcast will be available starting at 10 a.m. at: www.ulalaunch.com
And for the first time ever you can also watch the launch live via a live 360 stream on the NASA Television YouTube channel. The 360 degree broadcast starts about 10 minutes prior to lift off at:

Science plays a big role in this mission in tribute named in tribute to John Glenn. Over one third of the payload loaded aboard Cygnus involves science.
“The new experiments will include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and growth of fresh food in space,” according to NASA.
The astronauts will grow food in space, including Arabidopsis and dwarf wheat, in an experiment that could lead to providing nutrition to astronauts on a deep space journey to Mars.
“Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments. Cygnus also is carrying 38 CubeSats, including many built by university students from around the world as part of the QB50 program. The CubeSats are scheduled to deploy from either the spacecraft or space station in the coming months.”
Also aboard is the ‘Genes in Space-2’ experiment. A high school student experiment from Julian Rubinfien of Stuyvescent High School, New York City, to examine accelerated aging during space travel. This first experiment will test if telomere-like DNA can be amplified in space with a small box sized experiment that will be activated by station astronauts.
The Saffire III payload experiment will follow up on earlier missions to study the development and spread of fire and flames in the microgravity environment of space. The yard long experiment is located in the back of the Cygnus vehicle. It will be activated after Cygnus departs the station roughly 80 days after berthing. It will take a few hours to collect the data for transmission to Earth.

From a weather standpoint, Tuesday’s launch outlook is outstanding at this time.
According to meteorologists with the U.S. Air Force 45th Weather Squadron we are forecasting a 90 percent chance of “go” conditions at the 11:11 a.m. EDT launch time. The primary concern is for the possibility of cumulus clouds.
The forecast calls for temperatures of 75-76° F with on-shore winds peaking below 10 knots during the countdown.
In the event of a delay for any reason related to weather or technical issues a backup launch opportunity exists for Wednesday, April 19, and also looks promising.
The AF is also predicting the same 90 percent chance of “go” conditions at launch time. With the primary concern again being for the possibility of cumulus clouds.

The rocket was rolled out to pad 41 at about 9 a.m. EDT this morning Monday April 17, in a process that takes about 25 minutes
The rocket and spacecraft passed the Launch Readiness Review held by United Launch Alliance and Orbital ATK on April 15. Launch managers from ULA, Orbital ATK and NASA determined all is ready for Tuesday’s targeted launch to the ISS.
OA-7 is loaded with 3500 kg (7700 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.

The Orbital ATK Cygnus CRS-7 (OA-7) mission will launch aboard an Atlas V Evolved Expendable Launch Vehicle (EELV) in the 401 configuration vehicle. This includes a 4-meter-diameter payload fairing in its longest, extra extended configuration (XEPF) to accommodate the enhanced, longer Cygnus variant being used.

The first stage of the Atlas V booster is powered by the RD AMROSS RD-180 engine. There are no side mounted solids on the first stage. The Centaur upper stage is powered by the Aerojet Rocketdyne RL10C-1 engine.
Overall this is the 71st launch of an Atlas V and the 36th utilizing the 401 configuration.
The 401 is thus the workhorse version of the Atlas V and accounts for half of all launches.
