NASA Pool Prepares Astronauts for Upcoming Space Station Spacewalks


HOUSTON -- Astronauts aboard the International Space Station are scheduled to perform three consecutive spacewalks in October to upgrade and repair critical equipment outside the orbiting laboratory.

NASA astronauts Randy Bresnik and Mark Vande Hei will venture outside through the Quest airlock on Thursday for the first spacewalk beginning at 8:10 a.m. EDT. The duo will to remove and replace a defective latching end-effector on the Canadarm 2 robotic arm.

On October 10, Bresnik and Vande Hei will egress the airlock at about 8:10 a.m. to rotate a pump flow control assembly to prepare it for venting and its relocation in the near future. The astronauts will also replace a station video camera which has a pink discoloration on the lens.

One week later, on October 18, Bresnik and NASA astronaut Joe Acaba will perform a third orbital walk to add a high definition camera, replace another video camera on the Destiny Laboratory, and the two will lube select areas on the station.

Spacewalking preparations began several months ago by Bresnik, Vande Hei, and Acaba, both in the NASA mock-ups, and below the waters of the Neutral Buoyancy Laboratory located next to the Johnson Space Center near Houston.


Take a massive swimming pool, fill it with 6.2 million gallons of water, and throw in a large mock up of the space station into that pool. That's the NBL -- a special training pool which allows selected astronauts to suit up in their spacesuit and work submerged with a near feeling of weightlessness.

The NBL is located inside the Sonny Carter Training Facility, and is a critical training tool for many departments within NASA. Flight directors use the pool to refine spacewalk procedures and develop flight procedures. Teams can also verify hardware compatibility first before launching the equipment into space.

"It's a great way to train, and it's an amazing team sport," said NASA astronaut Victor Glover, a Navy commander and F/A-18 pilot, explained to this aerospace reporter. "What you see requires 30 or 40 people just to put two people into a space suit to train. You have a test director, a camera diver, two safety divers per every space suit, and you have a whole team of folks to make sure you're doing these things safely."

An astronaut will spend seven hours of training in the NBL pool for every hour they are scheduled to spend spacewalking.

Glover added that risks are involved with every spacewalk related to time and physics. One example, he discussed, is when astronauts work on the electrical side of the orbital outpost it is performed while the station is over the night side of the planet. Much like replacing a wall socket at home, the Sun is not generating power to the solar arrays for nearly 40 minutes.

Measuring 202-feet long by 102-feet wide, the NBL pool is loaded with strong filters. The pool's water is recycled every 19 hours, according to Glover, and it is chemically treated to stop bacteria growth. The water's temperature remains between 82° to 88° Fahrenheit to keep NASA support divers, who assist the submerged astronauts for long periods of time, warm and comfortable.

NASA-TV will provide live coverage of each spacewalk beginning at 6:30 a.m. each day.

Marine Test Pilot, Russian and Italian Launch to International Space Station

CAPE CANAVERAL, Fla. -- An American Marine Top Gun test pilot, a Russian biochemist, and an Italian Special Forces parachutist lifted off on Friday a top a Russian Soyuz rocket beginning a voyage to rendezvous and dock with International Space Station.

Nearly six hours later, the crew of three successfully docked to the Russian Rasvet module on the Earth facing side of the space station at 5:54 p.m. EDT -- seven minutes earlier than planned.

NASA astronaut Randy J. Bresnik, Russian Soyuz commander Sergey Ryazanskiy, and Europe's Paolo Nespoli, all three space veterans, will be busy with a multitude of science experiments; the arrival and undocking of several unmanned cargo crafts; and spacewalking as they prepare the orbital outpost for new hardware.

Launched from the historic launch site at Baikonur Cosmodrome in Kazakhstan at 11:41 a.m. EDT (9:41 p.m. local), today's lift-off occurred from the same pad Russia's Sputnik 1 launched from sixty years ago this October. That successful satellite launch in 1957 heralded the dawn of the space age.

As the Soyuz soared skyward into the darkening skies of sunset, a 400-foot golden flame pushed the rocket higher as it traveled eastward. Nearly nine minutes later, a strong jolt was felt by the crew as their Soyuz spacecraft separated from the rocket's third stage upon reaching orbit 125 miles above.

Space Station to Perform Three Orbit Chase of Solar Eclipse

CAPE CANAVERAL, Fla. -- Astronauts aboard the International Space Station may have the best windows for viewing the Great American Eclipse as they photograph and record August's astronomical event during three consecutive orbits.

Soaring 255 miles above, the six person crew of Expedition 52 will have detailed observation objectives in place as they point cameras from the Cupola's windows while they trek across North America once every 91 minutes. They will also be the first humans to witness this solar eclipse thanks to orbital mechanics.

In May 2012, NASA astronaut Don Pettit witnessed a solar eclipse from Earth orbit. "It is amazing to see an eclipse from orbit," Pettit recalled. "The shadow on Earth looks just like what you see in the physics and astronomy books."

Newly released ground tracks by NASA provided to AvGeekery.com show the space station's three positions as it passes through the Moon's penumbra during the midday hours of August 21 -- the height of solar eclipse across America. Astronauts will attach special solar filters to their 400 mm and 800 mm cameras as they approach their first observation's over the Pacific Ocean.

SpaceX Falcon 9 launch marks historic milestone at Kennedy Space Center

CAPE CANAVERAL, Fla. -- A uncrewed SpaceX cargo craft departed America's Space Coast on Saturday loaded with nearly three tons of supplies for astronauts living and working aboard the International Space Station.

The SpaceX launch marked the first reflight of a Dragon spacecraft, and also set a historic milestone from America's Spaceport.

A Space Exploration Technologies Corp. Falcon 9 rocket lifted off from the Kennedy Space Center's Pad-39A on June 3 at 5:07:38 p.m. EDT, blazing a trail out over the Atlantic Ocean. The lift-off marked the 100th rocket launch from the historic launch complex 39-A.

The launch pad was first used fifty years ago this November as the first Saturn V moon rocket launched during the uncrewed Apollo 4 mission. Pad 39-A later supported many notable space flights including Apollo 11's mission to first land man on the moon in 1969; America's first space station Skylab in 1973; the first space shuttle flight in 1981 and 81 subsequent shuttle flights; and today, SpaceX launches.

Signed in April 2014 by CEO Elon Musk, SpaceX has an exclusive twenty-year lease with NASA to use 39A for both uncrewed launches, and future crewed missions aimed at sending astronauts to the space station and Mars. A Dragon 2 spacecraft will be used for crewed flights to the station beginning in summer of 2018.

SpaceX Falcon 9 lifts-off from Kennedy Space Center with Inmarsat 5 F4

CAPE CANAVERAL, Fla. -- A high-speed broadband spacecraft designed to increase advanced data services to remote maritime and aviation locations lifted off on Monday from America's Space Coast.

Inmarsat 5 F4 Global Xpress satellite will expand high-speed broadband connectivity across the planet with Ka-Band service. The $240 million spacecraft will soon join a fleet of three fifth-generation telecommunications satellites in geo-stationary orbit.

Built by Boeing in El Segundo, California, the global communications spacecraft has twin solar arrays for a combined 42 meters -- longer than that of a Boeing 737 aircraft. Inmarsat is scheduled to operate on orbit for approximately 15 years.

"It's been a great afternoon and evening out at Kennedy Space Center," stated John Insprucker, SpaceX principal integration engineer, minutes following the craft release into space. "We counted down with excellent weather; launched right on time -- the first stage did great, the second stage went through two burns just as planned. Now, we've topped it off with the separation of Inmarsat 5 F4 for our Inmarsat customer."


A flawless countdown lead the Space Exploration Technologies Corp. (SpaceX) Falcon 9 to ignite it's nine Merlin engines on time, launching from the Kennedy Space Center's historic pad 39-A at 7:21 p.m. EDT. The white candlestick soared straight up and into the light blue clear skies before it began to veer toward the eastern horizon.

Air Force X-37B Space Shuttle Lands After 718 Days in Space


CAPE CANAVERAL, Fla. -- The U.S. Air Force unmanned scientific and military research space shuttle safely returned to America's Space Coast on Sunday completing 718 days in orbit.

The fourth flight of the fully automated shuttle began its deorbit early Sunday, and reentered the Earth's atmosphere about 25 minutes prior to the 8:00 a.m. EDT landing at the Kennedy Space Center's Shuttle Landing Facility.

"The landing of OTV-4 marks another success for the X-37B program and the nation," Lt. Col. Ron Fehlen, X-37B program manager, said. "This mission once again set an on-orbit endurance record and marks the vehicle's first landing in the state of Florida. We are incredibly pleased with the performance of the space vehicle and are excited about the data gathered to support the scientific and space communities."

Sunday's landing marked the X-37B's first return from space to land at the Florida Spaceport, and it will not be the last. The X-37B manufacture Boeing is renting the space center's Orbiter Processing Facility bay 1 to off-load experiments, refurbish the craft, and prepare it for relaunch from the Cape. Bay 1 was used for over three decades to service NASA's fleet of space shuttle's.

Once the command to return to Earth is given by the Air Force, the X-37B automatically descends from low earth orbit, reenters, and flies through the atmosphere to land on a planned runway. There is no one in a control room with a joystick flying it.

The program's fourth test flight into future robotic space planes began with its launch a top a United Launch Alliance Atlas V rocket in May 2015 from Cape Canaveral AFS. The 29-foot long shuttle resembles NASA's space shuttle orbiters at first glance, however the X-37B is 80% smaller fitted with small wings, twin vertical stableizers, and a windowless avionics cockpit.

“Today marks an incredibly exciting day for the 45th Space Wing as we continue to break barriers,” Brig. Gen. Wayne Monteith, commander of 45th Space Wing said. “Our team has been preparing for this event for several years, and I am extremely proud to see our hard work and dedication culminate in today’s safe and successful landing of the X-37B.”

In 1999, NASA begun the X37 project, however the space agency handed it over to DARPA (the Defense Advanced Research Projects Agency) in September 2004. DARPA is headquartered in Arlington, Virginia.

DARPA, originally formed in 1958 as the Advanced Research Projects Agency, is an office designed to prevent technological surprises against the United States, such as the Soviets launch of Sputnik in 1957. The OTV project partnership between the military, DARPA and NASA was announced in October 2006.

This flight was performed by the second mini shuttle of the Air Force's two shuttle fleet. The Air Force office also announced on Sunday the next X-37B will launch in late-2017. That launch will see the reflight of Boeing's first flown shuttle on it's third mission.
