       Astronauts Make History with 1st-ever All-Women Spacewalk   Expedition 61 Flight Engineers Christina Koch and Jessica Meir of NASA concluded their spacewalk, the first with only women. During the 7-hour, 17-minute spacewalk, the two NASA astronauts completed the replacement a failed power charging component, also known as a battery charge-discharge unit (BCDU). The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting lab’s systems. Mission control activated the newly installed BCDU and reported it is operating properly. The astronauts were also able to accomplish some get-ahead tasks including installation of a stanchion on the Columbus module for support of a new external ESA (European Space Agency) payload platform called Bartolomeo scheduled for launch to the station in 2020. Commander Luca Parmitano of ESA and NASA Flight Engineer Andrew Morgan assisted the spacewalkers. Parmitano operated the Canadarm2 robotics arm and Morgan provided airlock and spacesuit support. It was the eighth spacewalk outside the station this year. Space station crew members have now conducted 221 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have spent a total of 57 days, 20 hours, and 29 minutes working outside the station. It was the first spacewalk for Meir and the fourth for Koch, who now has spent a total of 27 hours and 48 minutes spacewalking. It is the first spaceflight for both women, who were selected in the 2013 astronaut class that had equal numbers of women and men. Koch arrived to the orbiting laboratory in March 2019 and will remain in space for an extended duration mission of 11 months to provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to prepare for human missions to the Moon and Mars. Meir became the 15th woman to spacewalk, and the 14th U.S. woman. It was the 43rd spacewalk to include a woman. Women have been performing spacewalks since 1984, when Russian cosmonaut Svetlana Savitskaya spacewalked in July and NASA astronaut Kathryn Sullivan spacewalked in October. The faulty BCDU is due to return to Earth on the next SpaceX Dragon resupply ship for inspection. Station managers will reschedule the three battery replacement spacewalks for a future date. In the meantime, the five planned spacewalks to repair a cosmic particle detector, the Alpha Magnetic Spectrometer, are still on the calendar for November and December.

U.S. astronauts Christina Koch and Jessica Meir stepped outside the International Space Station Friday morning, the first time in history that two women have done a spacewalk together. Koch and Meir were expected to spend more than five hours outside the space station to replace a failed power controller, but extended their spacewalk to "accomplish some get-ahead tasks on the space station," according to NASA. The astronauts spoke with President Donald Trump and Vice President Mike Pence during the spacewalk. The conversation marked the first time since the 1969 moon landing that a sitting president spoke directly to astronauts who were physically outside of a spacecraft in space, according to the White House. Trump called the two astronauts “very brave people” for their service on the space station. “I don’t think I want to do it. I must tell you that. But you are amazing people,” the president said, later adding, “You’re very brave, brilliant women.”   Meir told the president she and Koch saw the spacewalk as "just us doing our job." "It's something we've been training for six years," she said. "For us, it's just coming out here and doing our job today. We were the crew that was tasked with this assignment." "At the same time, we recognize that it is a historic achievement and we do of course want to give credit for all those who came before us," Meir added. "There has been a long line of female scientists, explorers, engineers and astronauts and we have followed in their footsteps to get us where we are today."  Meir said she hopes she and Koch provide inspiration "to everybody, not only women." "To everybody that has a dream, that has a big dream and that is willing to work hard to make that dream come true, something that all of us that have made our way up here have done all throughout our lives," she said. "And I can tell you, the hard work certainly did pay off." The remaining four astronauts aboard the International Space Station, all men, will stay inside while Koch and Meir complete their work. People took to social media Friday to celebrate "HERstory in the making," as NASA is calling the history-making event.

  • 0 A space shuttle should take about 10 hours to get to the moon. Why does it take 3 days?

    Special Blog Post BY:  C Stuart Hardwick, Award-Winning Scifi Author  Sept-28-2019     Q: A space shuttle should take about 10 hours to get to the moon.Incorrect. A space shuttle could never reach the moon, not in a zillion years, not unless it’s carried inside some much larger spacecraft that can reach the moon. Besides, the nice people in the museum won’t let you have their space shuttle.But I digress.    Q: Why does it take 3 days?You are confusing maximum speed with average speed.Like the space shuttle, the Apollo spacecraft went into low earth orbit at around 17,000 mph. Unlike the shuttle (which was then out of fuel except for what it needed to maneuver and reenter) an Apollo mission still had a nearly full S-IVB upper stage. When that fired, it accelerated itself, the SLA housing the lander, the lander (the LEM), and the Command and Service Modules (the CSM) to about 24,000 mph (11 km/s), fast enough to reach the moon in ten hours. But as soon as the engine cut off, the spacecraft started slowing down—still under the influence of Earth’s gravity. It slowed and slowed until it was barely moving (in space terms). At a mere 2,400 mph, it started accelerating again, this time toward the moon under lunar gravity.And that’s why it took three days (and will always take three days for a free return trajectory, regardless of spacecraft). The maximum speed at orbital insertion or trans-lunar injection is not the speed for the duration of the flight.I mention free return trajectory because, as a genuine rocket scientist recently explained to me at a conference, we are unlikely to want to send humans to either the moon or Mars on any other kind of trajectory, any time in the foreseeable future. A free return trajectory is one that will always take you back home if you just do nothing—useful in case anything goes wrong.Original Source: The original article on Quora will open in a new window CLICK HERE  Used for educational purposes.

  • 0 Q & A Interview by Max S.

    3.00 of 1 votes

    Below is a Question and Answer E-mail Interview done with a SVA Cadet. The Cadet "Max S." used this information in a school project.  I thought you'd enjoy reading it. My response to Question 4 talks about what I like about running Space Voyage summer camp. 1. What do you think is the most harsh condition in space? Temperature changes. The changes in temperature seem to be a real challenge. In low earth orbit astronauts in EVA and the orbiter experience negative 250 degrees F, then when in the sun experience positive 250 degrees F.  Consider that dry ice is about negative 112 degrees F and space is very cold.  Imagine the types of materials needed to handle those dramatic changes-- hundreds (even thousands) of times in a single 14 day mission.  The orbiter does a pancake flip to help control cabin temperature and EVA suits have more than 20 layers and a liquid cooling garment that nauts wear.    2. Which Apollo mission was the most important?  Why?  Hard to say a single one.  Apollo 1 was important because it demonstrated the need to be diligent in all aspects. Apollo 1 never flew; Three astronauts died in a simulation and perished when a spark from a faulty wire ignited materials in the 100% oxygen environment.  Apollo 1 cemented the American value that life is important to Americans. Apollo 13 was important since it involved overcoming the odds and finding creative ways to solve life threatening events.  American ingenuity, perseverance and teamwork were cemented into the space program as things to be valued.  Those two were important but Apollo 11 was the most important. 10,000 people supported a space program (program Apollo) that promised to put a man on the moon and return him safely to the Earth in less than 10 years.  Apollo 11 energized all parts of American government, education, technology and science like never before or since.  Apollo 11 cemented the notion that Americans can do anything and continues to this day of being probably the greatest achievement in the history of mankind.   3. What do you think is one of the most memorable space mission?  Besides Apollo 11, probably STS-51-L, the 25th shuttle mission and the 10th flight of Challenger. Most memorable since I was teaching Pre-IB science to sixth graders in Houston, Texas and refused to allow my students to watch the flight live on TV like the other 11 science teachers at Welch Middle School did.  Challenger, carrying the first teacher in space, experienced catastrophic failure when a Solid Rocket Booster (SRB) failed about 73 seconds after liftoff.  While NASA reported such a catastrophe would occur once in 100,000 flights, I felt with more than 200,000 parts from 5,000 vendors the chances were similar to winning a dollar in the Texas Lottery: 1 in 35.  Prior to teaching in Houston, I completed a 2,000 hour American Psychological Association (APA) internship that involved counseling, assessment and crisis intervention. My experiences as a psych in post suicide interventions (about one a week in Houston schools), gave me insight into the possible 'psychic trauma' that my students would experience if they witnessed a shuttle blowing up.  Unfortunately that's exactly what happened and many students were traumatized.  Interesting, at the same time, me and about 14 of my students were designing a shuttle simulation that today is Space Voyage.   4. What is your favorite thing at camp Space Voyage? I like the energy in the room, the willingness of staff to meet the needs of every student, and the way we see kids grow, persevere and figure things out.  I like the overall environment and the ability to add, change and improve as I like.  I like the way the camp uses technology to help learn, and I like the way the camp allows staff to teach students that technology is only a help and not the solution.  I like to teach students to be leaders by using the Axioms and by example.  I like the challenge of criticalities and I like to hear all the radio chatter that goes on behind the scenes that makes the camp so successful.  I like the celebrations and seeing kids smile and be happy.  I like inventing new activities and imagining what-else-we-could-do.  I like to see the room fully engaged with every student being productive. I like that Space Voyage is a living museum with old, current and cutting edge technologies... and I like that the camp allows me to study emerging technologies.  Most of all I like that Space Voyage invites ongoing studies where kids look forward to coming back, where they have fun and learn about what they might be (or not be) when they grow up. I enjoy getting the emails and letters from Air Force Academy and other college graduates thanking me for helping them and for creating Space Voyage for other kids to benefit from.  5. What do you think is the most important space discovery ever?  The most important discovery is the next one.

    Space Voyage Camp Registration is OPEN !   Summer Camp registration is open.   Thinking about camp, I took a minute to look for some inspirational art.  Desert & Space by Julien Kalkecker and Society6 really shows some inspiration. While we know that this number of ballons could never lift an astronaut with a full MMU (man maneuvering unit) weighing 325 pounds on Earth or Mars, it's still awesome to think about the possibilities.   The first man to use a MMU, called by NASA a Space Shuttle Extravehicular Mobility Unit (EMU) was Bruce McCandless in 1984. He used his hands to control 24 nozzle thrusters.  NASA says this MMU is capable of going 80 feet per second.  Quite fast, but in reality astronauts used a micro-burst technique. I'm not sure they ever went "full throttle" in space since the nitrogen used as a propellent was very limited. Google "first MMU flight" to learn more.  Click on google images for some really great photos.   Thank you, Julien Kaltnecker, for creating such awesome art.    See you at camp, I am,   Doc Palmere, Founder of Space Voyage   Source:
