Elon Musk’s dream and ultimate goal of establishing a permanent human presence on the Red Planet in the form of “A City on Mars” took a gigantic step forward with the game changing rocket landing and recovery technology vividly demonstrated by his firm’s Falcon 9 booster this past Monday, Dec. 21 – following a successful blastoff from the Florida space coast just minutes earlier on the first SpaceX launch since a catastrophic mid-air calamity six months ago.

“I think this was a critical step along the way towards being able to establish a city on Mars,” said SpaceX billionaire founder and CEO Elon Musk at a media telecon shortly after Monday night’s (Dec. 21) launch and upright landing of the Falcon 9 rockets first stage on Cape Canaveral Air Force Station, Fla.

NASA has just received a significant boost in the agency’s current budget after both chambers of Congress passed the $1.1 Trillion 2016 omnibus spending bill this morning, Friday, Dec. 18, which funds the US government through the remainder of Fiscal Year 2016.

As part of the omnibus bill, NASA’s approved budget amounts to nearly $19.3 Billion – an outstandingly magnificent result and a remarkable turnaround to some long awaited good news from the decidedly negative outlook earlier this year.

In the wake of NASA’s supremely successful inaugural test flight of the Orion deep space capsule on the EFT-1 mission in Dec. 2014, NASA is beefing up the critical thermal protection system (TPS) that will protect astronauts from the searing heats experienced during reentry as the human rated vehicle plunges through the Earth’s atmosphere after returning from ambitious expeditions to the Moon and beyond.

Based in part on lessons learned from EFT-1, engineers are refining Orion’s heat shield to enhance the design, ease manufacturing procedures and significantly strengthen is heat resistant capabilities for the far more challenging space environments and missions that lie ahead later this decade and planned further out in the future as part of NASA’s agency-wide ‘Journey to Mars’ initiative to send humans to the Red Planet in the 2030s.

On all future flights starting with Exploration Mission 1 (EM-1), the Orion crew module must Continue reading “Orion Gets Beefed Up, Silver-Metallic Thermal Protection Coating for Next Flight on EM-1”

NASA Awards Contract to Aerojet Rocketdyne to Restart RS-25 Engine Production for SLS Mars Rocket

The first RS-25 flight engine, No. 2059, is placed on the A-1 Test Stand at Stennis Space Center, Miss. The engines were built by Aerojet Rocketdyne and are being tested in 2015 and 2016 to certify them to fly on NASA’s new Space Launch System (SLS) rocket.

NASA took another big step on the path to propel our astronauts back to deep space and ultimately on to Mars with the long awaited decision to formally restart production of the venerable RS-25 engine that will power the first stage of the agency’s mammoth Space Launch System (SLS) heavy lift rocket, currently under development.

Aerojet Rocketdyne was awarded a NASA contract to reopen the production lines for the RS-25 powerplant and develop and manufacture a certified engine for use in NASA’s SLS rocket. The contract spans from November 2015 through Sept. 30, 2024.

The SLS is the most powerful rocket the world has ever seen and will loft astronauts in the Orion capsule on missions back to the Moon by around 2021, to an asteroid around 2025 and then beyond on a ‘Journey to Mars’ in the 2030s – NASA’s overriding and agency wide goal. The first unmanned SLS test flight is slated for late 2018.

The core stage (first stage) of the SLS will initially be powered by four existing RS-25 engines, recycled and upgraded from the shuttle era, and a pair of five-segment solid rocket boosters that will generate a combined 8.4 million pounds of liftoff thrust, making it the world’s most powerful rocket ever.

The newly awarded RS-25 engine contract to Sacramento, California based Aerojet Rocketdyne is valued at 1.16 Billion and aims to “modernize the space shuttle heritage engine to make it more affordable and expendable for SLS,” NASA announced on Nov. 23. NASA can also procure up to six new flight worthy engines for later launches.

“SLS is America’s next generation heavy lift system,” said Julie Van Kleeck, vice president of Advanced Space & Launch Programs at Aerojet Rocketdyne, in a statement.

“This is the rocket that will enable humans to leave low Earth orbit and travel deeper into the solar system, eventually taking humans to Mars.”

The lead time is approximately 5 or 6 years to build and certify the first new RS-25 engine, Van Kleek told Universe Today in an interview. Therefore NASA needed to award the contract to Aerojet Rocketdyne now so that its ready when needed.

The RS-25 is actually an upgraded version of former space shuttle main engines (SSMEs) originally built by Aerojet Rocketdyne.

The reusable engines were used with a 100% success rate during NASA’s three decade-long Space Shuttle program to propel the now retired shuttle orbiters to low Earth orbit.

Those same engines are now being modified for use by the SLS on missions to deep space starting in 2018.

But NASA only has an inventory of 16 of the RS-25 engines, which is sufficient for a maximum of the first four SLS launches only. Although they were reused numerous times during the shuttle era, they will be discarded after each SLS launch.

During a 535-second test on August 13, 2015, operators ran the Space Launch System (SLS) RS-25 rocket engine through a series of tests at different power levels to collect engine performance data on the A-1 test stand at NASA's Stennis Space Center near Bay St. Louis, Mississippi.  Credit: NASA

And since the engines cannot be recovered and reused as during the shuttle era, a brand new set of RS-25s will have to be manufactured from scratch.

Therefore, the engine manufacturing process can and will be modernized and significantly streamlined – using fewer part and welds – to cut costs and improve performance.

“The RS-25 engines designed under this new contract will be expendable with significant affordability improvements over previous versions,” added Jim Paulsen, vice president, Program Execution, Advanced Space & Launch Programs at Aerojet Rocketdyne. “This is due to the incorporation of new technologies, such as the introduction of simplified designs; 3-D printing technology called additive manufacturing; and streamlined manufacturing in a modern, state-of-the-art fabrication facility.”

“The new engines will incorporate simplified, yet highly reliable, designs to reduce manufacturing time and cost. For example, the overall engine is expected to simplify key components with dramatically reduced part count and number of welds. At the same time, the engine is being certified to a higher operational thrust level,” says Aerojet Rocketdyne.

The existing stock of 16 RS-25s are being upgraded for use in SLS and also being run through a grueling series of full duration hot fire test firings to certify them for flight, as I reported previously here at Universe Today.

Among the RS-25 upgrades is a new engine controller specific to SLS. The engine controller functions as the “brain” of the engine, which checks engine status, maintains communication between the vehicle and the engine and relays commands back and forth.

Each of the RS-25’s engines generates some 500,000 pounds of thrust. They are fueled by cryogenic liquid hydrogen and liquid oxygen. For SLS they will be operating at 109% of power, compared to a routine usage of 104.5% during the shuttle era. They measure 14 feet tall and 8 feet in diameter.

They have to withstand and survive temperature extremes ranging from -423 degrees F to more than 6000 degrees F.

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

Orion’s inaugural mission dubbed Exploration Flight Test-1 (EFT) was successfully launched on a flawless flight on Dec. 5, 2014 atop a United Launch Alliance Delta IV Heavy rocket Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

NASA’s MAVEN Orbiter Discovers Solar Wind Stripped Away Mars Atmosphere Causing Radical Transformation

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) orbiter mission has determined that ancient Mars suffered drastic climate change and lost its thick atmosphere and surface bodies of potentially life giving liquid water because it lost tremendous quantities of gas to space via stripping by the solar wind, based on new findings that were announced today, Nov. 5, at a NASA media briefing and in a series of scientific publications.

The process of Mars dramatic transformation from a more Earth-like world to its barren state today started about 4.2 Billion years ago as the shielding effect of the global magnetic field was lost as the planets internal dynamo cooled, Bruce Jakosky, MAVEN principal investigator at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado, Boulder, told Universe Today.

The radical transformation of ancient Mars from a warm world with significant bodies of standing water that could have supported life, to its current state as a cold, arid and desert-like world that’s rather inhospitable to life was caused by the loss of most the planet’s atmosphere as powerful streams of solar wind particles crashed into it and stripped it away due to the loss of the protective magnetic field as the planets core cooled.

“We think that the early magnetic field that Mars had would have protected the planet from direct impact by the solar wind and would have kept it from stripping gas off,” Jakosky told me.

“So it would have been the turn off of the magnetic field, that would have allowed the turn on of stripping of the atmosphere by the solar wind.”

“The evidence suggests that the magnetic field disappeared about 4.2 Billion years ago.”

The period of abundant surface water actively carving the Martian geology lasted until about 3.7 Billion years ago. The loss of the atmosphere by stripping of the solar wind took place from about 4.2 to 3.7 Billion years ago.

Billions of years ago, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. A thick atmosphere blanketed the planet and kept it warm.  Credit: NASA

With the release of today’s results, the MAVEN science team has accomplished the primary goal of the mission, which was to determine how and why Mars lost its early, thick atmosphere and water over the past four billion years. The atmosphere is composed mostly of carbon dioxide.

Since water is a prerequisite for life as we know it, determining its fate and longevity on Mars is crucial for determining the habitability of the Red Planet and its potential for supporting martian microbes, past of present if they ever existed.

“The NASA Mars exploration program has been focused on finding water,” said Michael Meyer, lead scientist for the Mars Exploration Program at NASA Headquarters.

“Water is the prime ingredient needed for life. It is a major factor in the climate and for shaping geology. And it is a critical resource for future human exploration.”

NASA’s goal is to send humans on a ‘Journey to Mars’ during the 2030s.

MAVEN arrived in orbit at Mars just over one year ago on Sept. 21, 2014.

The $671 Million MAVEN spacecraft’s goal is to study Mars tenuous upper atmosphere in detail for the very first time by any spacecraft and to explore the mechanisms of how the planet lost its atmosphere and life giving water over billions of years as well as determine the rate of atmospheric loss.

The new MAVEN data have enabled researchers to measure the rate of Mars atmospheric loss of gas to space via the action of solar wind stripping as well as the erosional effect of solar storms.

Based on measurements from MAVEN’s suite of nine state-of-the-art scientific instruments, the solar wind is stripping away gas at a rate of about 100 grams (equivalent to roughly 1/4 pound) every second today, in the form of carbon dioxide and oxygen, said David Brain, MAVEN co-investigator at LASP.

“Most of the stripping [of the Martian atmosphere] by the solar wind at Mars was thought to have taken place very early in the history of the solar system when the sun was much more active and when the solar wind was more intense. So today the rate of loss at Mars is low,” Jakosky said at the briefing.

“Today’s Mars is a cold dry desert-like environment. The atmosphere is thin and it’s not capable of sustaining liquid water at the surface today, it would freeze or evaporate very quickly. However when we look at ancient Mars we see a different type of surface, one that had valleys that looked like they were carved by water and lakes that were standing for long periods of time. We see an environment that was much more able to support liquid water.”

The MAVEN results were published today in nearly four dozen scientific papers in the Nov. 5 issues of the journals Science and Geophysical Research Letters.

I asked Jakosky; How much gas would have been lost from ancient Mars and what is the rough estimate for the ancient rate of loss to arrive at Mars thin atmosphere today?

“For the amount of gas that we think you would have to have been removed – let me start with the current Mars atmosphere which has a thickness of 6 millibars, that’s just under 1% as thick as the Earth’s atmosphere,” Jakosky replied.

“So we think you would have to remove an amount of gas that is about equivalent to what’s in Earth’s atmosphere today.”

“So the rate would have to have been a factor of about 100 to 1000 times higher, than today’s loss of 100 grams per second in order to have removed the gas early in that time period, which is consistent with what the models have predicted that the loss rate would have been back then in early history.”

What is the solar wind and how does it strip away the atmosphere?

“The solar wind is a stream of particles, mainly protons and electrons, flowing from the sun’s atmosphere at a speed of about one million miles per hour. The magnetic field carried by the solar wind as it flows past Mars can generate an electric field, much as a turbine on Earth can be used to generate electricity. This electric field accelerates electrically charged gas atoms, called ions, in Mars’ upper atmosphere and shoots them into space,” according to a NASA description.

MAVEN is just now completing its primary mission and starts the extended mission phase on Nov. 16.

The 5,400 pound MAVEN probe carries nine sensors in three instrument suites to study why and exactly when did Mars undergo the radical climatic transformation.

MAVEN’s observations will be tied in with NASA’s ongoing Curiosity and Opportunity surface roving missions as well as MRO and Mars Odyssey to provide the most complete picture of the fourth rock from the sun that humanity has ever had.

MAVEN thundered to space on Nov. 18, 2013 following a flawless blastoff from Cape Canaveral Air Force Station’s Space Launch Complex 41 atop a powerful United Launch Alliance Atlas V rocket.

International Space Station Achieves 15 Years of Continuous Human Presence in Orbit

The International Space Station (ISS) achieved 15 years of a continuous human presence in orbit, as of today, Nov. 2, aboard the football field sized research laboratory ever since the first Russian/American crew of three cosmonauts and astronauts comprising Expedition 1 arrived in a Soyuz capsule at the then much tinier infant orbiting complex on Nov. 2, 2000.

Today, the space station is host to the Expedition 45 crew of six humans – from America, Russia and Japan – that very symbolically also includes the first ever crew spending one year aboard and that highlights the outposts expanding role from a research lab to a deep space exploration test bed for experiments and technologies required for sending humans on interplanetary journeys to the Martian system in the 2030s.

The ISS was only made possible by over two decades of peaceful and friendly international cooperation by the most powerful nations on Earth on a scale rarely seen.

“I believe the International Space Station should be considered for the Nobel Peace Prize,” said NASA Administrator Charles Bolden last week during remarks to the Center for American Progress in Washington, DC., on October 28, 2015.

“Exploration has taught us more than we have ever known about our Universe and our place in it.”

“The ISS has already taught us what’s possible when tens of thousands of people across 15 countries collaborate so that human beings from different nations can live and work in space together.”

“Yet, for all these accomplishments, when you consider all the possibilities ahead of us you can only reach one conclusion; We are just getting started!”

“No better place to celebrate #15YearsOnStation! #HappyBday, @space_station! Thanks for the hospitality! #YearInSpace.” tweeted NASA astronaut Scott Kelly from the ISS today along with a crew portrait.

The space station is the largest engineering and construction project in space combining the funding, hardware, knowhow, talents and crews from 5 space agencies and 15 countries – NASA, Roscomos, ESA (European Space Agency), JAXA (Japan Aerospace and Exploration Agency) and CSA (Canadian Space Agency).

The collaborative work in space has transcended our differences here on Earth and points the way forward to an optimistic future that benefits all humanity.

The station orbits at an altitude of about 250 miles (400 kilometers) above Earth. It measures 357 feet (109 meters) end-to-end and has an internal pressurized volume of 32,333 cubic feet, equivalent to that of a Boeing 747.

The uninterrupted human presence on the station all began when Expedition 1 docked at the outpost on Nov. 2, 2000, with its first residents including Commander William Shepherd of NASA and cosmonauts Sergei Krikalev and Yuri Gidzenko of Roscosmos.

For the first station trio in November 2000, the vehicle included three modules; the Zarya module and the Zvezda service module from Russia and the Unity module from the US.

Over the past 15 years, after more than 115 construction and logistics flight, the station has grown by leaps and bounds from its small initial configuration of only three pressurized modules from Russian and America into a sprawling million pound orbiting outpost sporting a habitable volume the size of a six bedroom house, with additional new modules and hardware from Europe, Japan and Canada.

The ISS has been visited by over 220 people from 17 countries.

The “1 Year ISS crew” reflects the international cooperation that made the station possible and comprises current ISS commander NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko, who are now just past the half way mark of their mission.

“Over the weekend, I called NASA astronaut Scott Kelly, who is currently halfway through his one-year mission aboard the International Space Station, to congratulate him on setting the American records for both cumulative and continuous days in space,” Bolden said in a NASA statement released today.

“I also took the opportunity to congratulate Commander Kelly — and the rest of the space station crew — for being part of a remarkable moment 5,478 days in the making: the 15th anniversary of continuous human presence aboard the space station.”

The complete Expedition 45 crew members include Station Commander Scott Kelly and Flight Engineer Kjell Lindgren of NASA, Flight Engineers Mikhail Kornienko, Oleg Kononenko and Sergey Volkov of the Russian Federal Space Agency (Roscosmos) and Flight Engineer Kimiya Yui of the Japan Aerospace Exploration Agency.

For the first nine years, the station was home to crews of two or three. Starting in 2009 the crew size was doubled to a permanent crew of six humans after the habitable volume, research facilities, equipment and supporting provisions had grown sufficiently.

“Humans have been living in space aboard the International Space Station 24-7-365 since Nov. 2, 2000. That’s 15 Thanksgivings, New Years, and holiday seasons astronauts have spent away from their families. 15 years of constant support from Mission Control Houston. And 15 years of peaceful international living in space,” says NASA.

The US contributed and built the largest number of segments of the space station, followed by Russia.

NASA’s Space Shuttles hauled the US segments aloft inside the orbiters huge payload bay, starting from the first construction mission in 1998 carrying the Unity module to the final shuttle flight STS-135 in 2011, which marked the completion of construction and retirement of the shuttles.

With the shuttle orbiters now sitting in museums and no longer flying, the Russian Soyuz capsule is the only means of transporting crews to the space station and back.

The longevity of the ISS was recently extended from 2020 to 2024 after approval from President Obama. Most of the partners nations have also agreed to the extension. Many in the space community believe the station hardware is quite resilient and hope for further extensions to 2028 and beyond.

“The International Space Station, which President Obama has extended through 2024, is a testament to the ingenuity and boundless imagination of the human spirit. The work being done on board is an essential part of NASA’s journey to Mars, which will bring American astronauts to the Red Planet in the 2030s,” says Bolden.

“For 15 years, humanity’s reach has extended beyond Earth’s atmosphere. Since 2000, human beings have been living continuously aboard the space station, where they have been working off-the-Earth for the benefit of Earth, advancing scientific knowledge, demonstrating new technologies, and making research breakthroughs that will enable long-duration human and robotic exploration into deep space.”

A key part of enabling long duration space missions to Mars is the 1 Year ISS Mission.

Scott Kelly recently set the US records for most time in space and longest single space mission.

In coming years, additional new pressurized modules and science labs will be added by Russia and the US.

And NASA says the stations crew size will expand to seven after the US commercial Starliner and Dragon space taxis from Boeing and SpaceX start flying in 2017.

NASA is now developing the new Orion crew capsule and mammoth Space Launch System (SLS) heavy lift rocket to send astronauts to deep space destination including the Moon, asteroids and the Red Planet.

In the meantime, Kelly and his crew are also surely looking forward to the arrival of the next Orbital ATK Cygnus resupply ship carrying science experiments, provisions, spare parts, food and other goodies after it blasts off from Florida on Dec. 3 – detailed in my story here.

The SLS, America’s first human-rated heavy lift rocket intended to carry astronauts to deep space destinations since NASA’s Apollo moon landing era Saturn V, has passed a key design milestone known as the critical design review (CDR) thereby clearing the path to full scale fabrication.

NASA also confirmed they have dropped the Saturn V white color motif of the mammoth rocket in favor of burnt orange to reflect the natural color of the SLS boosters first stage cryogenic core. The agency also decided to add stripes to the huge solid rocket boosters.

NASA announced that the Space Launch System (SLS) has “completed all steps needed to clear a critical design review (CDR)” – meaning that the design of all the rockets components are technically acceptable and the agency can continue with full scale production towards achieving a maiden liftoff from the Kennedy Space Center in Florida in 2018.

“We’ve nailed down the design of SLS,” said Bill Hill, deputy associate administrator of NASA’s Exploration Systems Development Division, in a NASA statement.

Blastoff of the NASA’s first SLS heavy lift booster (SLS-1) carrying an unmanned test version of NASA’s Orion crew capsule is targeted for no later than November 2018.

Indeed the SLS will be the most powerful rocket the world has ever seen starting with its first liftoff. It will propel our astronauts on journey’s further into space than ever before.

SLS is “the first vehicle designed to meet the challenges of the journey to Mars and the first exploration class rocket since the Saturn V.”

Crews seated inside NASA’s Orion crew module bolted atop the SLS will rocket to deep space destinations including the Moon, asteroids and eventually the Red Planet.

“There have been challenges, and there will be more ahead, but this review gives us confidence that we are on the right track for the first flight of SLS and using it to extend permanent human presence into deep space,” Hill stated.

The core stage (first stage) of the SLS will be powered by four RS-25 engines and a pair of five-segment solid rocket boosters (SRBs) that will generate a combined 8.4 million pounds of liftoff thrust in its inaugural Block 1 configuration, with a minimum 70-metric-ton (77-ton) lift capability.

Overall the SLS Block 1 configuration will be some 10 percent more powerful than the Saturn V rockets that propelled astronauts to the Moon, including Neil Armstrong, the first human to walk on the Moon during Apollo 11 in July 1969.

The SLS core stage is derived from the huge External Tank (ET) that fueled NASA Space Shuttle’s for three decades. It is a longer version of the Shuttle ET.

NASA initially planned to paint the SLS core stage white, thereby making it resemble the Saturn V.

But since the natural manufacturing color of its insulation during fabrication is burnt orange, managers decided to keep it so and delete the white paint job.

“As part of the CDR, the program concluded the core stage of the rocket and Launch Vehicle Stage Adapter will remain orange, the natural color of the insulation that will cover those elements, instead of painted white,” said NASA.

There is good reason to scrap the white color motif because roughly 1000 pounds of paint can be saved by leaving the tank with its natural orange pigment.

This translates directly into another 1000 pounds of payload carrying capability to orbit.

“Not applying the paint will reduce the vehicle mass by potentially as much as 1,000 pounds, resulting in an increase in payload capacity, and additionally streamlines production processes,” Shannon Ridinger, NASA Public Affairs spokeswomen told Universe Today.

After the first two shuttle launches back in 1981, the ETs were also not painted white for the same reason – in order to carry more cargo to orbit.

“This is similar to what was done for the external tank for the space shuttle. The space shuttle was originally painted white for the first two flights and later a technical study found painting to be unnecessary,” Ridinger explained.

NASA said that the CDR was completed by the SLS team in July and the results were also further reviewed over several more months by a panel of outside experts and additionally by top NASA managers.

“The SLS Program completed the review in July, in conjunction with a separate review by the Standing Review Board, which is composed of seasoned experts from NASA and industry who are independent of the program. Throughout the course of 11 weeks, 13 teams – made up of senior engineers and aerospace experts across the agency and industry – reviewed more than 1,000 SLS documents and more than 150 GB of data as part of the comprehensive assessment process at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where SLS is managed for the agency.”

“The Standing Review Board reviewed and assessed the program’s readiness and confirmed the technical effort is on track to complete system development and meet performance requirements on budget and on schedule.”

The final step of the SLS CDR was completed this month with another extremely thorough assessment by NASA’s Agency Program Management Council, led by NASA Associate Administrator Robert Lightfoot.

“This is a major step in the design and readiness of SLS,” said John Honeycutt, SLS program manager.

The CDR was the last of four reviews that examine SLS concepts and designs.

NASA says the next step “is design certification, which will take place in 2017 after manufacturing, integration and testing is complete. The design certification will compare the actual final product to the rocket’s design. The final review, the flight readiness review, will take place just prior to the 2018 flight readiness date.”

“Our team has worked extremely hard, and we are moving forward with building this rocket. We are qualifying hardware, building structural test articles, and making real progress,” Honeycutt elaborated.

Numerous individual components of the SLS core stage have already been built and their manufacture was part of the CDR assessment.

The SLS core stage is being built at NASA’s Michoud Assembly Facility in New Orleans. It stretches over 200 feet tall and is 27.6 feet in diameter and will carry cryogenic liquid hydrogen and liquid oxygen fuel for the rocket’s four RS-25 engines.

On Sept. 12, 2014, NASA Administrator Charles Bolden officially unveiled the world’s largest welder at Michoud, that will be used to construct the core stage, as I reported earlier during my on-site visit – here.

The first stage RS-25 engines have also completed their first round of hot firing tests. And the five segment solid rocket boosters has also been hot fired.

NASA decided that the SRBs will be painted with something like racing stripes.

“Stripes will be painted on the SRBs and we are still identifying the best process for putting them on the boosters; we have multiple options that have minimal impact to cost and payload capability, ” Ridinger stated.

With the successful completion of the CDR, the components of the first core stage can now proceed to assembly of the finished product and testing of the RS-25 engines and boosters can continue.

“We’ve successfully completed the first round of testing of the rocket’s engines and boosters, and all the major components for the first flight are now in production,” Hill explained.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center (KSC).

The SLS/Orion stack will roll out to pad 39B atop the Mobile Launcher now under construction – as detailed in my recent story and during visit around and to the top of the ML at KSC.

NASA astronaut Scott Kelly has just broken the American record for most time spent in space – at 383 days and counting – as part of his groundbreaking yearlong mission living aboard the International Space Station (ISS), where he currently serves as station commander.

See Kelly break the US spaceflight endurance record on the ISS at the “SPEED OF SOUND” in the beautifully space themed music video (above) set to the worldwide hit song by rock band Coldplay.

The video recounts a flurry of highlights from the yearlong space station mission with his partner, Russian cosmonaut Mikahail Kornienko, and the rest of the rotating cast of international crewmates.

On October 16, 2015, Kelly surpassed the US time in space record of 382 days previously held by NASA astronaut Mike Fincke.

The ‘1 Year ISS mission’ is aimed at conducting research to explore the impact of long term stays in space on the human body and aid NASA’s long term plans for a human ‘Journey to Mars’ in the 2030s.

“Records are meant to be broken. Look fwd to one of my colleagues surpassing my end 500+ days on our #JourneyToMars!’ Kelly tweeted from the ISS about his record breaking achievement.

As of today, October 20, Kelly has reached the 206 day mark aboard the ISS, of his planned 342 days in space. He’s now about a month past the half way mark.

In addition to his scientific research, Kelly has been a prolific photographer of all things space – including natural wonders and natural disasters like Hurricane Joaquin.

Here’s his newly released photo titled ‘Earth Art From Australia.’

Kelly accumulated his time in space during multiple spaceflights. Altogether this is his fourth mission and second long duration stay aboard the ISS. This flight also marks his second stint as station commander – as a member of the current Expedition 45 crew.

To be sure, Kelly is not merely passing Fincke’s record days but actually smashing through it by many months because he still has a long way to go until he returns home to Earth.

At the conclusion of his yearlong mission when he plummets back home in a Russian Soyuz capsule – along with Kornienko – on March 2, 2016, he will have compiled 522 total days living in space.

Kelly will also become the first American to spend a year in space, a feat previously achieved by only four Russian cosmonauts – all in the 1980s and 1990s aboard Russia’s Mir space station.

Next week on Thursday, Oct. 29, Kelly will break another American record for the single-longest spaceflight.

“On Oct. 29 on his 216th consecutive day in space, he will surpass astronaut Michael Lopez-Alegria’s record for the single-longest spaceflight by an American. Lopez-Alegria spent 215 days in space as commander of the Expedition 14 crew in 2006.”

Kelly and Kornienko are spending a year aboard the ISS, “testing the limits of human research, space exploration and the human spirit,” says NASA officials.

The pair launched to the ISS in March 2015 along with Russian cosmonaut Gennady Padalka. He recently returned to Earth in September 2015 after setting the record for most time spent in space by any Earthling – with an accumulated total of 879 days living and working in space.

During their 342 days in space, Kelly and Kornienko are specifically “participating in studies in space that provide new insights into how the human body adjusts to weightlessness, isolation, radiation and stress of long-duration spaceflight. Kelly’s twin brother, former astronaut Mark Kelly, will participate in parallel twin studies on Earth to help scientists compare the effects on the body and mind in space.”

“The investigations in progress on the space station will help scientists better understand how to protect astronauts as they travel into deep space and eventually on missions to the Red Planet. The strong U.S.-Russian collaboration during the one-year mission is an example of the global cooperation aboard the space station that is a blueprint for international partnerships to advance shared goals in space exploration. Strengthening international partnerships will be key in taking humans deeper into the solar system,” according to NASA.
