Astronauts Drew Feustel & Ricky Arnold will be taking your questions in a Video Answer Time session. We’ll collect your questions and send them to space to be answered by the astronauts on Friday, May 18. We’ll record their answers and post them on Wednesday, May 23 here on NASA’s Tumblr. Make sure to ask your question now by visiting http://nasa.tumblr.com/ask!
Andrew J. Feustel was selected by NASA in 2000. He has been assigned to Expedition 55/56, which launched in March 2018. The Lake Orion, Michigan native has a Ph.D. in the Geological Sciences, specializing in Seismology, and is a veteran of two spaceflights. Follow Feustel on Twitter and Instagram.
Richard R. Arnold II was selected as an astronaut by NASA in May 2004. The Maryland native worked in the marine sciences and as a teacher in his home state, as well as in countries such as Morocco, Saudi Arabia, and Indonesia. Follow Arnold on Twitter and Instagram.

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry written by NASA astronaut Scott Tingle.

Our crew just finished the final training event before the launch. Tomorrow, at 13:20 local time (Baikonur), we will strap the Soyuz MS-07 spacecraft to our backs and fly it to low Earth orbit. We will spend 2.5 days in low Earth orbit before docking to the MRM-1 docking port on the International Space Station (ISS). There we will begin approximately 168 days of maintenance, service and science aboard one of the greatest engineering marvels that humans have ever created.
Today was bittersweet. Ending a 2-year process of intense training was welcomed by all of us. We are very tired. Seeing our families for the last time was difficult. I am pretty lucky, though. My wife, Raynette, and the kids have grown up around military service and are conditioned to endure the time spent apart during extended calls-to-duty. We are also very much anticipating the good times we will have upon my return in June. Sean and Amy showed me a few videos of them mucking it up at Red Square before flying out to Baikonur. Eric was impressed with the Russian guards marching in to relieve the watch at Red Square. Raynette was taking it all in stride and did not seem surprised by any of it. I think I might have a family of mutants who are comfortable anywhere. Nice! And, by the way, I am VERY proud of all of them!
Tomorrow’s schedule includes a wake-up at 04:00, followed by an immediate medical exam and light breakfast. Upon returning to our quarters, we will undergo a few simple medical procedures that should help make the 2.5-day journey to ISS a little more comfortable. I’ve begun prepping with motion sickness medication that should limit the nausea associated with the first phases of spaceflight. I will continue this effort through docking. This being my first flight, I’m not sure how my body will respond and am taking all precautions to maintain a good working capability. The commander will need my help operating the vehicle, and I need to not be puking into a bag during the busy times. We suit up at 09:30 and then report to the State Commission as “Готовы к Полёту”, or “Ready for Flight”. We’ll enter the bus, wave goodbye to our friends and family, and then head out to the launch pad. Approximately 2 kilometers from the launch pad, the bus will stop.
The crew will get out, pee on the bus’s tire, and then complete the last part of the drive to the launch pad. This is a traditional event first done by Yuri Gagarin during his historic first flight and repeated in his honor to this day. We will then strap in and prepare the systems for launch. Next is a waiting game of approximately 2 hours. Ouch. The crew provided five songs each to help pass the time. My playlist included “Born to Run” (Springsteen), “Sweet Child O’ Mine” (Guns and Roses), “Cliffs of Dover” (Eric Johnson), “More than a Feeling” (Boston), and “Touch the Sky” (Rainbow Bridge, Russian). Launch will happen precisely at 13:20.
I think this sets the stage. It’s 21:30, only 6.5 hours until duty calls. Time to get some sleep. If I could only lower my level of excitement!

The launch of Apollo 13.
The race to land astronauts on the Moon was getting tense 50 years ago this week. Apollo 6, the final uncrewed test flight of America’s powerful Moon rocket, launched on April 4, 1968. Several technical issues made for a less-than-perfect launch, but the test flight nonetheless convinced NASA managers that the rocket was up to the task of carrying humans. Less than two years remained to achieve President John F. Kennedy’s goal to put humans on the Moon before the decade was out, meaning the Saturn V rocket had to perform.
After the April 1968 Apollo 6 test flight (pictured above), the words of Deke Slayton (one of the original Mercury 7 astronauts) and intense competition with a rival team in the Soviet Union propelled a 12-member panel to unanimously vote for a Christmas 1968 crewed mission to orbit the Moon.
The Saturn V rocket stood about the height of a 36-story-tall building, and 60 feet (18 meters) taller than the Statue of Liberty. Fully fueled for liftoff, the Saturn V weighed 6.2 million pounds (2.8 million kilograms), or the weight of about 400 elephants.
Stand back, Ms. Frizzle. The Saturn V generated 7.6 million pounds (34.5 million newtons) of thrust at launch, creating more power than 85 Hoover Dams. It could launch about 130 tons (118,000 kilograms) into Earth orbit. That’s about as much weight as 10 school buses. The Saturn V could launch about 50 tons (43,500 kilograms) to the Moon. That’s about the same as four school buses.
On Christmas Eve 1968, the Saturn V delivered on engineers’ promises by hurling Frank Borman, Jim Lovell and Bill Anders into lunar orbit. The trio became the first human beings to orbit another world. The Apollo 8 crew broadcast a special holiday greeting from lunar orbit and also snapped the iconic earthrise image of our home planet rising over the lunar landscape.
The crew of Apollo 9 proved that they could pull the lunar module out of the top of the Saturn V’s third stage and maneuver it in space (in this case high above Earth). The crew named their command module “Gumdrop.” The Lunar Module was named “Spider.”
Saturn-V AS-505 provided the ride for the second dry run to the Moon in 1969. Tom Stafford, Gene Cernan and John Young rode Command Module “Charlie Brown” to lunar orbit and then took Lunar Module “Snoopy” on a test run in lunar orbit. Apollo 10 did everything but land on the Moon, setting the stage for the main event a few months later. Young and Cernan returned to walk on the Moon aboard Apollo 16 and 17 respectively. Cernan, who died in 2017, was the last human being (so far) to set foot on the Moon.
The launch of Apollo 11—the first mission to land humans on the Moon—provided another iconic visual as Saturn-V AS-506 roared to life on Launch Pad 39A at Kennedy Space Center in Florida. Three days later, Neil Armstrong and Buzz Aldrin made the first of many bootprints in the lunar dust (supported from orbit by Michael Collins).
Saturn V rockets carried 24 humans to the Moon, and 12 of them walked on its surface between 1969 and 1972. Thirteen are still alive today. The youngest, all in their early 80s, are moonwalkers Charles Duke (Apollo 16) and Harrison Schmitt (Apollo 17) and Command Module Pilot Ken Mattingly (Apollo 16, and also one of the heroes who helped rescue Apollo 13). There is no single image of all the humans who have visited the Moon.
The Saturn V’s swan song was to lay the groundwork for establishing a permanent human presence in space. Skylab, launched into Earth orbit in 1973, was America’s first space station, a precursor to the current International Space Station. Skylab’s ride to orbit was a Saturn IV-B 3rd stage, launched by a Saturn 1-C and SII Saturn V stages.
This was the last launch of a Saturn V, but you can still see the three remaining giant rockets at the visitor centers at Johnson Space Center in Texas and Kennedy Space Center in Florida and at the United States Space and Rocket Center in Alabama (near Marshall Space Flight Center, one of the birthplaces of the Saturn V).
The Saturn V was retired in 1973. Work is now underway on a fleet of rockets. We are planning an uncrewed flight test of Space Launch System (SLS) rocket to travel beyond the Moon called Exploration Mission-1 (EM-1). “This is a mission that truly will do what hasn’t been done and learn what isn’t known,” said Mike Sarafin, EM-1 mission manager at NASA Headquarters in Washington.
