Soyuz Heads to Space Station with New Crew, Return Transportation for One-Year Mission Team (Press Release - September 1)
Three crew members representing Russia, Denmark and Kazakhstan have launched to the International Space Station to provide a new ride home for the station’s one-year crew and continue important research that advances NASA's journey to Mars.
Sergey Volkov of Roscosmos, Andreas Mogensen of ESA (European Space Agency) and Aidyn Aimbetov of the Kazakh Space Agency launched aboard Soyuz TMA-18M from the Baikonur Cosmodrome in Kazakhstan at 12:37 a.m. EDT on Wednesday (10:37 a.m. in Baikonur). They are set to dock to the station at 3:42 a.m. on Friday, Sept. 4. NASA TV coverage of docking will begin at 3 a.m.
At 2:40 p.m. Saturday, Sept. 5, NASA TV will provide a live broadcast as Expedition 44 Commander Gennady Padalka of Roscomos hands over command of the space station to Expedition 44 Flight Engineer Scott Kelly of NASA. Expedition 45 begins on Sept. 11 when Padalka, Mogensen and Aimbetov undock from the orbital outpost in the Soyuz spacecraft designated TMA-16M and return to Earth. The Soyuz TMA-16M carried Padalka, Kelly, and Roscosmos’ Mikhail Kornienko to space in March. Because each Soyuz remains in orbit for about six months, the spacecraft swap is necessary at the midway point of the one-year mission.
With the arrival of Volkov, Mogensen and Aimbetov, nine people will be aboard the orbiting laboratory for the first time since 2013. The three join Expedition 44 Flight Engineers Kelly and Kjell Lindgren of NASA, Commander Padalka and Flight Engineers Oleg Kononenko and Kornienko of Roscosmos, and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA).
On Tuesday, Sept. 15, Kelly and Kornienko will reach the halfway point of their one-year mission to advance understanding of the medical and psychological challenges astronauts face during long duration spaceflight, in addition to developing countermeasures that will help minimize adverse effects. The pair will spend 342 consecutive days living in space before returning to Earth with Volkov in March 2016 aboard the Soyuz TMA-18M.
In the coming months, Expedition 45 crew members will conduct more than 250 science investigations in fields such as biology, Earth science, human research, physical sciences, and technology development.
The recently installed CALorimetric Electron Telescope (CALET) searches for dark matter, measures cosmic rays and observes sources of high-energy phenomena in the galaxy. CALET seeks answers for several unknowns, including the origin of cosmic rays, how cosmic rays accelerate and move across the galaxy, and the existence of dark matter and its relation to nearby cosmic ray sources. Once scientists take an inventory of the highest-energy radiation in space, they may be able to characterize the radiation environment experienced by humans and encountered by space electronics. This may help determine risk of exposure to this type of radiation.
Ongoing station research also includes the Flame Extinguishment Experiment-2 JAXA (FLEX-2J), a study of combustion in microgravity. Fires burn differently in space, where fuels form spherical droplets and flames burn in a globular shape rather than teardrop. The crew studies the interactions of flames on the motion and ignition, or non-ignition, of millimeter-sized droplets. Results could provide key insights and improve computer modeling of fuel combustion to aid in reducing emissions and improving fuel efficiency in space and on Earth.
During the second half of the marathon one-year mission, the team will continue a wide variety of human research studies, such as the Assessing Telomere Lengths and Telomerase Activity in Astronauts (Telomeres). Telomeres are "caps" on the ends of chromosomes that protect them from fraying, much like the aglet on the end of a shoelace. Telomeres shorten over time, and the rate at which this occurs can be increased by stress, leading to accelerated aging, cardiovascular disease, cancer and an impaired immune system. The Telomeres investigation uses crew member blood samples to examine how telomeres and telomerase, an enzyme that maintains the length of telomeres, are affected by space travel and to better evaluate the impact of future spaceflight.
The International Space Station is a convergence of science, technology and human innovation that enables us to demonstrate new technologies and make research breakthroughs not possible on Earth. It has been continuously occupied since November 2000 and, since then, has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next giant leap in exploration, including future missions to an asteroid and Mars.

20th Century Fox
Since NASA has been vigorously promoting The Martian through its website and online social media, just thought I'd share this latest trailer for the Ridley Scott-directed movie that stars Matt Damon. Based on the bestselling novel by Andy Weir and out in theaters nationwide on October 2, The Martian chronicles the exploits of a NASA astronaut who has to find a way to survive on the Red Planet's surface for four years as he waits for help after being left stranded by his crew following a Martian dust storm. Here's hoping Ridley Scott made a film that will be as critically-acclaimed and enjoyed by audiences as Alfonso Cuarón's Gravity and Christopher Nolan's Interstellar were. NASA could use the additional PR if it wants its "JourneyToMars" hashtag on Twitter to continue meaning something years from now.

NASA Concludes Series of Engine Tests for Next-Gen Rocket (Press Release)
NASA has completed the first developmental test series on the RS-25 engines that will power the agency’s new Space Launch System (SLS) rocket on missions deeper into space than ever before.
The test series wrapped up Thursday with a seventh hot fire test of a developmental RS-25 engine on the A-1 Test Stand at NASA’s Stennis Space Center in Bay St. Louis, Mississippi. The test ran for a full-duration 535 seconds.
“The completion of this test series is an important step in getting SLS ready for the journey to Mars,” said Steve Wofford, engines manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where the SLS Program is managed for the agency. “The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time.”
The series was designed to collect valuable data on performance of the RS-25 engine, a former space shuttle main engine operating at higher thrust levels in order to provide the power needed for the SLS vehicle. Of particular interest is data that will aid in development of a new engine controller, or “brain,” to monitor engine status and communicate programmed performance needs.
“These are extremely reliable engines. We are testing them again because we want to ensure that the engine performs as required with a new engine controller, higher propellant inlet pressures and lower temperatures that are part of the SLS design. We also want to mitigate any risks on the ground before flight,” Wofford said.
Four RS-25 engines will help power the SLS core stage during launch. Firing simultaneously at 109 percent of its operating level, the engines will provide approximately 2 million pounds of thrust. The engines will operate in conjunction with a pair of five-segment solid rocket boosters for a total of 8.4 million pounds of thrust to lift the initial 70-metric-ton (77-ton) SLS off the launch pad. The SLS eventually will evolve to a 130-metric-ton (143-ton) configuration that will enable missions to such deep space destinations as an asteroid and Mars.
Testing of RS-25 flight engines for the initial SLS missions will begin at Stennis this fall. In addition to testing RS-25 flight engines, Stennis operators will employ their collective expertise to test the SLS core stage. The B-2 Test Stand at Stennis is being renovated to conduct tests on the SLS flight core stage prior to its first uncrewed mission. That testing will involve installing the flight stage on the stand and firing its four RS-25 engines simultaneously, just as during an actual launch.
“What a great time to be at Stennis,” Center Director Rick Gilbrech said. “When it comes to powering the future of the deep space exploration program for this country, this is the front lines, where we enable those missions to fly.”
The developmental tests began with a Jan. 9 hot fire and resumed in May after scheduled work was completed on the high-pressure industrial water system that provides the thousands of gallons of water needed during an engine test. Aerojet Rocketdyne of Sacramento, California, is the prime contractor for the RS-25 engine work.
“This was a great test series for Stennis,” said Ronnie Rigney, RS-25 project manager at Stennis. “Our teams built up a lot of history with space shuttle main engines and were able to use that expertise to meet very challenging test specifications for the RS-25. The testing done here will help ensure the engines perform as needed during actual SLS missions.”

Mobile Launcher Mods Will Support NASA's Next-Generation Rocket and Spacecraft (Press Release)
NASA's mobile launcher (ML) is shaping up nicely as modifications continue on the ground structure that will launch the agency's Space Launch System rocket and Orion spacecraft on the journey to Mars and other deep-space destinations.
"We just finished up a major construction phase of the mobile launcher," said Eric Ernst, NASA ML project manager. "We were actually able to accelerate some of the work."
NASA recently selected J.P. Donovan Construction Inc. of Rockledge, Florida, to begin the next phase of work on the 380-foot-tall (including the base), 10.5-million-pound steel structure at NASA's Kennedy Space Center in Florida.
J.P. Donovan Construction will install and integrate ground support equipment (GSE) systems onto the mobile launcher to modify the structure with the systems necessary to assemble, process and launch NASA's integrated Space Launch System rocket and Orion spacecraft. The scope of work includes the installation of mechanical, electrical and fluid subsystems that will support the SLS rocket.
According to Ernst, this phase will include the installation of more than 800 mechanical, fluid and electrical panels, about 300,000-plus feet of cabling, and miles of tubing and piping.
"One of our big challenges is that SLS, Orion and GSE systems are all in development concurrently," Ernst said. "Now we are working to develop an install design for the hardware. There are a lot of unique challenges."
Members of the media recently toured the ML and saw first-hand all of the upgrades and modifications that have been completed so far. The ML was originally developed to support Ares I. The base and tower structure were modified to accommodate the much larger SLS/Orion configurations. These modifications included structural reinforcement of the base and tower and increased exhaust hole to accommodate the much larger launch vehicle.
"To increase the size of the exhaust hole and strengthen the base, we had demolition of over 750 tons of steel, and fabrication and installation of more than 1,000 tons of new steel," said Mike Taylor, project manager for J.P. Donovan.
A series of lines will connect the ML to various parts of the rocket to provide the necessary power, fuel, and communications until launch. These umbilical lines release at liftoff and then retract to clear the way for the rocket. The base of the ML will contain the tail service mast umbilicals. The tower will contain several umbilicals, including the crew access arm, the Orion service module umbilical, and several umbilicals that will provide power, cryogenics and stability to the SLS rocket.
The ML is planned to be rolled to the Vehicle Assembly Building in early 2017.
Overseeing modification to the ML is one of many ways the Ground Systems Development and Operations Program is helping to prepare Kennedy to process and launch the next-generation vehicles and spacecraft designed to achieve NASA's goals for space exploration. To achieve this transformation, the NASA and contractor workforce is developing the necessary ground systems while refurbishing and upgrading infrastructure and facilities to accommodate government, commercial and other customers' needs.

Earlier this month, Virgin Galactic posted this photo on Twitter showing the successor to the VSS Enterprise after it was secured to the underbelly of its mothership, the VMS Eve, at The Spaceship Company for a fit-check. While SpaceShipTwo's replacement (which was initially known as the VSS Voyager) is still far from completing construction, it is nice to know that Sir Richard Branson's aerospace firm is making strides towards returning to flight following last October's tragedy in California's Mojave Desert. Can't wait to see this bird soar in the sky once more.

Countdown to Deep Space Continues with Latest RS-25 Test (Press Release - August 13)
NASA’s countdown to deep space continued today with a 535-second test of its Space Launch System (SLS) RS-25 rocket engine to collect engine performance data at NASA's Stennis Space Center near Bay St. Louis, Mississippi. SLS will launch astronauts in the Orion spacecraft on missions to deep space and eventually on the journey to Mars. Operators on the A-1 Test Stand at Stennis are conducting the test series to qualify an all-new engine controller and put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a SLS mission.
One final test of this RS-25 developmental engine is planned in this series; testing of flight engines begins later this fall.
More than 1,200 people, including elected officials and community leaders, media and social media representatives, and NASA and contractor employees and family members viewed the test. Guests saw Stennis facilities and test stands, the Aerojet Rocketdyne engine assembly facility, and the Pegasus barge that will transport the SLS core stage from NASA's Michoud Assembly Facility in New Orleans to Stennis for testing then to Kennedy Space Center in Florida for launch.
An initial 70-metric-ton (77-ton) SLS configuration will use four RS-25 engines for the core stage, along with two five-segment solid rocket boosters, providing more lift to orbit than any current launch vehicle. The core stage for the first SLS and Orion integrated flight – Exploration Mission-1 – also will be tested at Stennis. That test will involve simultaneous firing of the four RS-25 engines just as during an actual launch.
The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system for deep space exploration. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time. Aerojet Rocketdyne of Sacramento, California, is the prime contractor for the RS-25 engine work.

Welding Preparations For Orion Spacecraft at Michoud Assembly Facility (Press Release)
At NASA’s Michoud Assembly Facility in New Orleans, engineers are welding together the Orion crew module pathfinder in preparation for the welding process set to begin later this summer on the Orion spacecraft for Exploration Mission-1. This pathfinder, including the barrel section shown here, is a full-scale version of the current spacecraft design. It is used to demonstrate the manufacturing and assembly procedures that will be used to produce flight hardware for Orion’s next mission, when the spacecraft will fly atop the agency’s Space Launch System rocket. Several pieces of Orion’s primary structure for that mission have already arrived at Michoud for processing.

Orion Begins Critical Design Review Milestone (Press Release)
NASA’s Orion Program kicked off its critical design review at the agency’s Johnson Space Center in Houston the week of Aug. 3, a major program milestone that will ensure the spacecraft’s design is ready for its deep space missions atop NASA’s Space Launch System (SLS) rocket.
Orion, which successfully flew about 3,600 miles into space last year during an uncrewed flight test, is being developed to send astronauts to new destinations in the solar system, including an asteroid and on toward Mars. During its next mission, Orion will venture to a distant lunar orbit beyond the far side of the moon.
“Our team across the country has been working incredibly hard to develop a spacecraft capable of expanding humanity’s frontier in the solar system,” said Mark Geyer, Orion Program manager. “Since even before flying Orion in space last year, we’ve been moving at full steam toward our first flight on SLS, and this review gives us a chance to make sure all systems and their designs meet our requirements and are in sync before we continue pressing ahead.”
The review is a months-long process where engineers delve into the details of the spacecraft’s systems and subsystems to evaluate their maturity and involves thousands of documents. The milestone is a rallying point for those with technical stakes in successfully building and flying future Orion missions to ensure all elements are in sync before moving ahead with full-scale fabrication, assembly, integration and testing.
It will include an evaluation of common aspects of the spacecraft for Exploration Mission (EM)-1 and the spacecraft for EM-2, the first Orion mission with astronauts, such as the spacecraft’s structures, pyrotechnics, Launch Abort System, guidance, navigation and control and software, among many other elements. Systems unique to EM-2 will be addressed at a later critical design review for the mission in the fall of 2017.
Not only will Orion technical experts take a close look at the spacecraft, but engineers working on SLS, which recently completed its own critical design review, the ground systems needed for launch and other elements needed to execute successful missions, such as mission operations and safety and mission assurance, will be on hand during the review to provide insight.
“We’re working through our critical design review now so that we can balance evaluating individual components with the hardware manufacturing needs we have to start our assembly and integration activities,” said Geyer.
The Orion Program’s critical design review is targeted for completion in late October.
