Yuri Gagarin – Hero of the Soviet Union and First Ambassador to the Cosmos

Gagarin - 1964

Yuri Gagarin – 1964


Today marks the anniversary of one of the most historic moments in human history. It was on this day in 1961, that Soviet cosmonaut Yuri Gagarin became the first human to take a journey into outer space. Aboard his Vostok spacecraft, not only did Gagarin become the first person in space, he also was the first to orbit the Earth — something NASA didn’t accomplish until its third manned Mercury mission, some nine months later.

While strapped to the top of a Soviet Vostok-K rocket, Gagarin hummed and whistled “Lilies of the Valley”, cracked jokes, and found plenty of time to laugh, all the while waiting for the ignition below to send him where no man had gone before.

Gagarin : Thank you. Goodbye. See you soon, dear friends. Goodbye, see you soon.

“Poyekhali! (Off we go!)”

Gagarin spent 108 minutes from launch to landing, completing a single orbit of the Earth. It took 25 minutes for ground controllers to be sure he had successfully reached orbit. Gagarin remained calm through the whole ordeal 1 and seemed to rather enjoy himself. He described weightlessness as an unusual, yet enjoyable, experience and radioed back the things he could see out of the windows in his capsule.

A 42-second retrofire burn took place over Angola, approximately 5,000 miles from his landing site. When the commands were initiated to separate the service module from the reentry module, a bundle of wires unexpectedly kept them attached. The two components began reentry together, but finally separated following some extreme gyrations. The gyrations continued after separation, but Gagarin radioed that “Everything is OK”, reasoning that the gyrations could be expected from the spherical shape of the craft and didn’t want to “make noise” about it. At 7km above the ground, Gagarin was ejected — as planned 2 — from the Vostok and his parachute immediately deployed. Vostok fell until about 2.5km (8,200 feet) before its main parachute deployed. A couple of schoolgirls witnessed Vostok’s landing and described the situation: “It was a huge ball, about two or three metres high. It fell, then it bounced and then it fell again. There was a huge hole where it hit the first time.”




Gagarin landed on the ground as a world hero. The Soviets were emboldened by their great accomplishment, and you could be certain that the early American space program had to pick their collective jaws off the floor and wonder how they would catch up.

We tip our hats to Yuri Gagarin and the bold first step he took to get us to where we are now–more than half a century later.

  1. Just prior to launch, Gagarin’s pulse was at a mere 64 beats per minute.
  2. It wasn’t until 1971 that the Soviets acknowledged that he didn’t land with his craft. The Fédération Aéronautique Internationale regulations required that a person land with their craft for it to count as a successful spaceflight. The Soviet government forced Gagarin to lie in press conferences to get the FAI to certify his flight, which they did.

Yesterday Was A Big Day For SpaceX

Yesterday was a big day for Elon Musk and his space launch services company SpaceX. On April 9, 2016, SpaceX launched its Falcon 9 rocket from Cape Canaveral. The rocket was topped with the company’s Dragon capsule, filled with 7,000 pounds of supplies destined for the International Space Station. Included in the payload was the 3,100 pound Bigelow Expandable Activity Module (BEAM), Bigelow Aerospace’s attempt to demonstrate its expandable space habitats.

The highlight of the mission, designated CRS-8, was SpaceX’s first successful landing of its Falcon 9 rocket on a droneship (christened “Of Course I Still Love You”) in the Atlantic Ocean. This feat is something SpaceX had tried and failed four times previously. SpaceX has successfully landed its Falcon 9 on land, but that challenge paled in comparison to a landing on a barge being tossed around by Atlantic currents.

SpaceX has put a huge emphasis on making its programs efficient and reusable. Their hope is that their methods will drive down the costs of putting people and equipment into orbit and beyond, and make launches much more common. Friday’s successful landing of the Falcon 9 was a huge step in that direction.

All in all, Friday’s success should serve as an important milestone in space exploration. It also highlights the ever increasing transfer of space access from governments to commercial industries.

Check out the amazing video below, of the Falcon 9 landing on ‘Of Course I Still Love You’.

Unreal.

Dragon will arrive at the ISS tomorrow, April 10.

Wordless Wednesday: An occasional feature in which interesting images are showcased with nothing more than an image caption. These images often become the subject of future full-length posts.

Tour the International Space Station

Have you ever wanted to visit the International Space Station? Without a whole lot of education, extreme determination, and a fair helping of luck, chances are you won’t be visiting it in-person anytime soon. But, that doesn’t mean you can’t take a virtual tour of humanity’s only off-planet home. With the multimedia below, get a feel for what life aboard the International Space Station is like. No spacesuit required.

ESA Panoramas

The European Space Agency (ESA) put together the following 360° panorama of the ISS’s Russian Zvezda module. Notice how there are work surfaces that could only function in a weightless environment. For example, pan straight up towards the ‘ceiling’. (Note: After you hit play, you’ll want to click the full-screen button in the bottom right corner of the video.)

This 360° panorama allows you to explore the International Space Station’s third module, Zvezda. Launched on 12 July 2000, the Russian module supplies life support for the Station and crewquarters. All five of Europe’s Automated Transfer Vehicles docked with the module.

The images to create this view were taken by ESA astronaut Samantha Cristoforetti during her Futura mission in 2015; the cosmonaut in the picture is Gennady Padalka.

Two other views like this are also available on YouTube thanks to the ESA. Check out the Zarya and Unity modules as well.

ESA Interactive Tour

Next up, we have an interactive presentation that you’re going to have to go see for yourself. Check out this interactive tour of nearly the entire ISS. Turn on the map overlay and you can jump to individual sections of the station, or just tour it manually by clicking on the blue arrows. (I managed to get myself lost!) Video clips are interspersed throughout the tour for a more-detailed look.

Just before ESA astronaut Samantha Cristoforetti left the International Space Station after 199 days, she took up to 15 pictures inside each module. Now, the images have been stitched together to create this interactive panorama.

These panoramas offer a snapshot of the International Space Station as it was in June 2015, after moving the Leonardo storage module to a new location.

Wasn’t that cool?

Commander Sunita Williams Tour

One more for today. While not interactive like the other two, this video is one of my favorite tours of the ISS.

In her final days as Commander of the International Space Station, Sunita Williams of NASA recorded an extensive tour of the orbital laboratory and downlinked the video on Nov. 18, just hours before she, cosmonaut Yuri Malenchenko and Flight Engineer Aki Hoshide of the Japan Aerospace Exploration Agency departed in their Soyuz TMA-25A spacecraft for a landing on the steppe of Kazakhstan. The tour includes scenes of each of the station’s modules and research facilities with a running narrative by Williams of the work that has taken place and which is ongoing aboard the orbital outpost.

 

The 2012 video is somewhat long, 25 minutes, but by the end of it you find yourself wishing it would go on longer. Commander Sunita Williams takes us all throughout the space station while demonstrating various features and functions. I especially enjoyed her taking us inside the docked Soyuz capsule that she would be dropping back to Earth in, mere hours after creating this video.

Book Review: Packing For Mars by Mary Roach

Packing For Mars cover

  • Title: Packing For Mars
  • Author: Mary Roach
  • Printed Pages: 334
  • Publish Year: August 2nd 2010 (W. W. Norton & Company)
  • Recommended For: People that want all of the dirty details about spaceflight that NASA tends not to advertise, those that enjoy Mary Roach’s humor and wit, and anyone who wants to find out just how ‘wrong’ some of that ‘Right Stuff’ was.

First Lines: “To the rocket scientist, you are a problem. You are the most irritating piece of machinery he or she will ever have to deal with. You and your fluctuation metabolism, your puny memory, your frame that comes in a million different configurations.”

Review:

I’ve read this book twice now. I read it when it was released in 2010.  I wasn’t familiar with Mary Roach at the time, but I was particularly interested in the history of spaceflight at the time. While waiting to board a few-hour flight, I saw this book in one of the airport book shops. I read the cover and knew I had to read it on the flight. My new Kindle was a novelty to me at the time, so I decided I would purchase the electronic version to read on the plane. I ran into snags trying to get my Kindle to connect to the airport’s WiFi. While in line to board, I figured out a way to turn my smartphone into a hotspot, connect the Kindle to that connection, and then download the book. It was a close call, but ultimately I had my book.

Packing For Mars kept me entertained for the entire 3-hour flight. My fellow aisle mates had to have been curious about what I thought was so funny because I couldn’t help cracking up at Roach’s witty humor. Before I knew it, the captain was already announcing that we’d be landing soon.

Then, I read it again in 2016 in a cabin in the woods, in Alaska, in the winter. I enjoyed the book even more the second time and picked up on things that I didn’t catch the first time. My knowledge of the US space program is much greater than it was the first time I read this book, and this helped me make mental connections that weren’t apparent the first time. In a sense, I’m saying that this is a book that grows with you.

Mary Roach covers nearly everything in her book. She highlights just how unusual an environment outer space is to the human body. This book reveals nearly everything you could imagine. Serious critical attention is spent on how one goes to the bathroom in space, how sex would work (speculating on whether some might already know the answer to this), how you eat, how you sleep, the risks, the rewards, and the awkwardness.

Roach takes our hero astronauts and cosmonauts and reveals a side of them that’s often overlooked: the fact that they don’t have superpowers, they’re people just like you and me.

One thing I couldn’t help but laughing at after reading this book is that one of the differences between me and an astronaut is that I wear diapers way less than they do!

I’m going to avoid trying to list everything the book covers, and instead I just want to encourage you to check it out for yourself. You don’t even have to be a space-nerd like myself to appreciate this book; it will entertain virtually anyone.

Selected Lines:

As when astronaut Mike Mullane was asked by a NASA psychiatrist what epitaph he’d like to have on his gravestone. Mullane answered, “A loving husband and devoted father,” though in reality, he jokes in Riding Rockets, “I would have sold my wife and children into slavery for a ride into space.”


Among the 106 items left on the moon’s surface by Neil Armstrong and Buzz Aldrin are four urine collection assemblies—two large and two small. Who wore which remains a matter of conjecture.


If it’s cordless, fireproof, lightweight and strong, miniaturized, or automated, chances are good NASA has had a hand in the technology. We are talking trash compactors, bulletproof vests, high-speed wireless data transfer, implantable heart monitors, cordless power tools, artificial limbs, dustbusters, sports bras, solar panels, invisible braces, computerized insulin pumps, fire-fighters’ masks.


 

 

My Rating: I have no problem giving this book a 5/5, for making me laugh through turbulence on an airplane, for satisfying some of my greatest curiosities about space, and for making me see my space heroes in a new light: still as amazing as they were when I was a kid, but now with a greater sense of kinship.

Happy March Equinox: An Explanation

March Equinox graphic

Today is the March Equinox. You’ve probably already heard it a few times today; people running around proclaiming with utmost exuberance how today is the first day of Spring. After the long winters that some of us endure, the arrival of Spring is welcome news. But what is really going on today? After all, where I live it still feels like the middle of Winter, but flowers were already blooming on a trip I took to California a couple of weeks ago1. If we based “The First Day of Spring” on climate patterns, regions across the globe would be recognizing a wide variety of days throughout the year.

When someone says today is the first day of Spring, what they really mean (whether they know it or not) is that today represents an equinox; specifically, the March Equinox.2 On Earth, an equinox is the point in its orbit around the Sun when both hemispheres are equally illuminated; our tilted Earth lines up to a point in which the Sun passes directly over the equator. This happens twice a year, on the March and September equinoctes (which I learned today is the proper plural form of the word equinox).

Contrary to popular belief, the day of the equinox does not represent the day where daylight and darkness are equal. You can thank geometry, the atmosphere, and the Sun’s angular diameter to cause that equality to happen at different times geographically. What today does mean though, is that the equinoctes are the only two days in which the Sun rises due-East and sets due-West, and which the Sun would pass directly overhead from an observer on the equator.

One other very important thing that you must know if you don’t learn anything else today. Way too many people believe that the equinoctes are the only day of the year that an egg can be balanced on its end. While its true that on the equinox an egg can be balanced, it’s also true of every other day of the year; it makes no difference!

There are other times during the year (read: our orbit around the Sun) that we recognize Earth residing at a special place.  There’s Perihelion (which we went over in January) and Aphelion, and then the widely-celebrated solstices; but I’ll save that for another time.

Happy March Equinox!

  1. In fact, while it may have still been Winter to the San Diegans giving me quizzical looks for swimming in the ocean without a wet suit, to an Alaskan like myself it felt like an unusually warm Summer’s day!
  2. What about them being called the Spring  and Fall (or their Latin names, Vernal and Autumnal) equinoctes? Well, that wasn’t exactly fair to those in the Southern Hemisphere, whose seasons are opposite those in the Northern Hemisphere.

Juno: NASA’s Second New Frontiers Mission

Juno Mission Insignia

NASA’s New Frontiers program is a set of solar system exploration missions designed to address “strategic goals in planetary science through a series of moderate size space missions” (you can read the entire program plan here). New Frontiers consolidates a number of long-term space missions into a single program that share a funding source, management structure, and goals, yet maintain their independent identities. New Horizons, NASA’s recent mission to Pluto and the Kuiper Belt, is considered the first mission of the New Frontiers program. The second mission is named Juno. Launched in 2011 with its sights set on our solar system’s red-spotted giant, Juno is poised to arrive at Jupiter on July 4, 2016. Let’s take a look at the mission and what we can expect to learn.

Juno: What’s In a Name?

Juno takes its name from Greek and Roman mythology. NASA draws the connection between the spacecraft and the myths as such:

Jupiter drew a veil of clouds around himself to hide his mischief. It was Jupiter’s wife, the goddess Juno, who was able to peer through the clouds and reveal Jupiter’s true nature. The Juno spacecraft will also look beneath the clouds to see what the planet is up to, not seeking signs of misbehavior, but helping us to understand the planet’s structure and history.

 

(It’s probably for the best that they left out the part about how Juno was, in addition to being Jupiter’s wife, also his sister.)

Launch and Earth Fly-by

Juno launched atop the reliable and powerful Atlas V rocket engine on August 5, 2011. This engine contained five solid rocket boosters, along with a Centaur upper stage engine. The launch was flawless. After the solid rocket boosters were expended and jettisoned, the Centaur upper stage ignited and burned for six minutes, placing Juno in a parking orbit around the Earth. Juno coasted for thirty minutes towards the destination for the second Centaur burn. 40 minutes after lift-off from Cape Canaveral, the second Centaur burn was executed. It burned for nine minutes as it accelerated Juno on a trajectory to escape Earth’s orbit. From there, the Centaur engine separated from the spacecraft and Juno was on its own. Juno unfurled her solar panels and settled into a five-year journey to her mythical partner.

Juno underwent a series of deep space maneuvers that brought it back near Earth, two years and two months into its voyage. By now, Juno had already traveled 1.6 billion kilometers (994 million miles). Juno came within 559 kilometers (347 miles) of Earth, borrowing our planet’s gravity to boost its speed with an additional 3.9 kilometers per second (8,800 miles per hour). By the time Juno reaches Jupiter, it will have traveled more than 2,800 million kilometers (1.7 billion miles).

While near Earth, Juno did more than just steal some of our velocity. Juno’s science team activated a number of the spacecraft’s instruments and pointed them at Earth, acting as a sort of dress rehearsal for Jupiter.

Juno will be the second spacecraft to orbit and study Jupiter, preceded by the Galileo mission that performed from 1989 to 2003.

At Jupiter

Once Juno arrives at Jupiter on July 4, 2016, it will begin conducting its primary mission objectives. Juno will orbit Jupiter in a highly-elliptical orbit that will take it sweeping in close to the planet over one of its poles, zipping past the other pole in about two hours, before heading out beyond the orbit of Jupiter’s moon Callisto, repeating every 14 days.

Juno is loaded with instruments that will measure the oxygen and hydrogen ratios in Jupiter’s atmosphere, determine the mass of Jupiter’s core, map the gas giant’s magnetic and gravitational fields, and other important observations and experiments. These will allow us to determine how Jupiter formed, determine its structure below the clouds, and establish the source of the planet’s magnetic field.

JunoCam

Juno is also equipped with a visible light camera named JunoCam. Due to Jupiter’s damaging radiation and magnetic fields, JunoCam is only expected to operate for about 7 or 8 orbits; however, while it’s alive it’s expected to produce some fantastic images. Its specific targets will include Jupiter’s polar region and lower-latitude cloud belts, and will boast a resolution of 15 kilometers (9.3 miles) per pixel.

One of the best things about JunoCam is its strong emphasis on education and public outreach. For months now, a JunoCam website has been accepting images of Jupiter captured by amateur astronomers. These images will be publicly discussed during the next couple of months before a round of voting occurs to select the locations on Jupiter for JunoCam to image. Once the images have been captured and sent to Earth, the raw data will be posted on the JunoCam website for anyone to process and share.

On Monday, March 14, 2016, the European Space Agency’s (ESA) robotic explorer, ExoMars, is slated to launch from the Baikonur Cosmodrome in Kazakhstan. Seven months later, ExoMars will arrive at the red planet and begin a number of scientific investigations that were designed to help determine whether live ever existed on Mars.

ExoMars Programme

ESA is establishing ExoMars as a two-part program (they spell it programme). The first is the part that’s launching in a few days: an orbiter with an entry, descent, and landing module. The second component is scheduled for a 2018 launch and will include a rover. Roscosmos, the Russian space agency, is a partner with the ESA for the entire program.

The goal of the program is to “demonstrate a number of essential flight and in-situ enabling technologies that are necessary for future exploration missions, such as an international Mars Sample Return mission” and to operate “a number of important scientific investigations”. The latter investigations are designed to search for both past and present life on Mars, understand how the water and geochemical environment varies across the planet, and sample Mars’s atmosphere.

This year’s mission includes an orbiter that will sample trace gases, as well as a landing module that study the environment at its landing site (it will be stationary once it lands). The lander even has a name: Schiaparelli. The name comes from the 17th century Italian astronomer Giovanni Virginio Schiaparelli.

Part of the entire program are a number of assessment tools to evaluate the performance of the various components of the mission, to aid in the design of future missions.

The planned 2018 mission will include a rover with a two-meter drill that will allow access deeper into the Martian soil than we have been able to get to before.

Arrival at Mars is expected on October 19, 2016. For more information on the mission, check out ESA’s mission site.

Looking Back on America's First Female Astronauts

NASA Astronaut Group 8 class logo

On January 16, 1978, NASA selected its first group of new astronauts since 1969. This new class of 35 astronaut candidates was named Astronaut Group 8, but colloquially referred to as the “TFNG: 35 New Guys”1 While there were 35 members of the class, for the first time they couldn’t all be referred to as “guys”. Astronaut Group 8 would produce many firsts in the way of diversity: the first African-American in space, the first Asian-American in space, and the first Jewish-American, among others. Today we highlight the six women of Astronaut Group 8: Shannon W. Lucid, Margaret Rhea Seddon, Kathryn D. Sullivan, Judith A. Resnik, Anna L. Fisher and Sally K. Ride. These would become America’s first female space explorers.

From left to right are Shannon W. Lucid, Margaret Rhea Seddon, Kathryn D. Sullivan, Judith A. Resnik, Anna L. Fisher, and Sally K. Ride. NASA selected all six women as their first female astronaut candidates in January 1978, allowing them to enroll in a training program that they completed in August 1979.

Out of the six women of Astronaut Group 8, Shannon Lucid spent more time in space and flew on the most spaceflights. By the time she retired from NASA, she had flown to space on five separate flights and held a number of NASA spaceflight records as a result of her prolonged stay on the now-extinct Russian space station, Mir; Lucid was the only American woman that had the honor of serving upon Mir. In 1996, she became the first woman to receive a Congressional Space Medal of Honor which are awarded to astronauts “who in the performance of his duties has distinguished himself by exceptionally meritorious efforts and contributions to the welfare of the Nation and of mankind”. (Uhh, “his” and “himself”? Ahem!)  Of the six women in her class, Lucid was the only mother at the time of selection into the astronaut program (though, she wasn’t the first mother in space… we’ll get to that in a minute).

Lucid spent a total of 223 days, 2 hours, and  50 minutes in space during her career.

After her tenure as an astronaut, Lucid served as NASA’s Chief Scientist from February 2002 until September 2003. She also served as CAPCOM during numerous Space Shuttle and International Space Station crews. She retired from NASA in 2012.

Margaret Rhea Seddon

Margaret Rhea Seddon was the first medical doctor to travel to space. During her years as an astronaut, she flew on three separate missions. Her medical expertise was invaluable for the numerous experiments that she worked on during her missions in space, as well as the research she conducted on Earth. In 1981, Seddon married fellow Group 8 astronaut Robert L. Gibson and the two became the first active duty married astronauts.

During her three space flights, Seddon spent a total of 30 days, 2 hours, and 21 minutes in space. Her responsibilities during her 19 years at NASA included: helicopter search and rescue physician, serving on the NASA Life Sciences Advisory Committee and the NASA and International Bioethics Task Forces, and in-flight medical operations. While an active-duty astronaut, she continued to work part-time as an emergency room physician in various hospitals.

Seddon retired from NASA in 1997, remaining active in the medical community.

Kathryn D. Sullivan

Kathryn D. Sullivan made history in 1984 when she became the first American woman to conduct an EVA (extravehicular activity), spacewalking for 3-1/2 hours to demonstrate the feasibility of satellite refueling. This accomplishment came on her very first trip into space, during STS-41-G. In total, Sullivan visited space during three missions: STS-41-G, STS-31, and STS-45. STS-31 was an especially important mission, as they carried the Hubble Space Telescope into orbit, deploying it at an orbit altitude record at the time, of 612 kilometers (380 miles). Her work on STS-45, her final space voyage, included a number of research experiments as part of the Spacelab mission dedicated to the NASA ‘Mission to Planet Earth’. The results of that research provided a wealth of information about Earth’s climate and atmosphere.

During her three flights, she spent a total of 22 days, 4 hours, and 49 minutes in space.

In 2014, Sullivan was confirmed by the U.S. Senate to serve as the Under Secretary of Commerce for Oceans and Atmosphere and NOAA Administrator.

Anna L. Fisher

Anna Lee Fisher in 1980

In 1984, Anna Lee Fisher became the first mother in space. You might not immediately realize the significance of this, but I think it’s an important first. In the 1980s women were still fighting to be considered equals among men in the workplace. Much more so than now, moms were generally expected to stay home and raise the children while the fathers worked. So here you have a mother that not only does everything a mother does, but she works hard, trains to become an astronaut, and travels to space. Cracking the glass ceiling? More like smashing through Earth’s atmosphere!

Fisher is also extremely educated: she earned a Bachelor of Science in Chemistry in 1971, a Doctor of Medicine in 1976, and also earned a Master of Science in Chemistry in 1987–all from UCLA.

During her single flight, she spent 7 days, 23 hours, and 45 minutes in space.

As of 2014, Fisher was listed as a management astronaut with NASA and was working on NASA’s next generation crewed space program, among other duties.

(As an aside, the image of Anna Fisher above is one of my all-time favorite space images. The look of wonder and courage in her eyes stimulates some of the same emotions I had as a child watching these people take their trips into the skies in their shuttles. It represents a moment in our collective history, in which were just beginning to establish ourselves in a world that was much bigger than we had ever known before.)

Sally K. Ride

Sally Kristen Ride made history on June 18, 1983, when she became the first American woman in space (Russia put the first two women into space: Valentina Tereshkova and Svetlana Savitskaya). On that mission, STS-7, she also became the first woman to operate the shuttle’s robotic arm and the first to use it to retrieve a satellite from orbit. She flew a second flight in 1984, STS-41-G, with fellow Group 8 member Kathryn Sullivan.

During her two missions, she spent a total of 14 days, 7 hours, and 46 minutes in space.

In an interview with USA Today:

 In elementary school, there (were) lots of girls who were interested in science, and that’s true today. For whatever reason, I didn’t succumb to the stereotype that science wasn’t for girls. I got encouragement from my parents. I never ran into a teacher or a counselor who told me that science was for boys. A lot of my friends did.

 

Following the Challenger disaster, Ride served as a member of the Presidential Commission that investigated the accident. After NASA, Ride founded Sally Ride Science, a non-profit organization with a mission to “inspire young people in science, technology, engineering, and math (STEM) and to promote STEM literacy.”

Ride was always humble about it, but she was, and still is, a true inspiration to millions.

Ride passed away on July 23, 2012, while battling pancreatic cancer.

Judith A. Resnik

Not all of these stories have as happy of an ending as one would hope. On her second Shuttle mission, Judy Resnik was assigned to STS-51-L aboard Challenger. 73 seconds after lift-off, Challenger’s rocket boosters exploded and the orbiter broke apart. All seven members of the crew lost their lives.

Resnik earned a Bachelor of Science degree in Electrical Engineering from Carnegie-Mellon University in 1970, and a Doctorate in Electrical Engineering from University of Maryland in 1977.

Resnik’s first flight (STS-41-D), in 1984, made her the second American female in space, and the first Jewish-American in space. That mission had the crew deploy three satellites into orbit, as well as deploy the OAST-1 solar array. The array, once unfolded, was 13 feet wide and 102 feet long–“it’s up, and it’s big!” she reported to mission control. When folded, it was a mere 7 inches deep. The array demonstrated the feasibility of large lightweight solar arrays in space. Her total time in space as a result of that mission was 6 days, 56 minutes, and 4 seconds.

Resnik was posthumously awarded the Congressional Space Medal of Honor.

As of May 2015, nearly 60 women have flown into space. Along with Russian cosmonauts Valentina Tereshkova and Svetlana Savitskaya, these are the women that demolished barriers and showed the world that anyone that had the drive and work ethic required could make it in any industry that they desired to be a part of.
