Comings and goings continue apace on the International Space Station! After living and working fruitfully for six months in space aboard the ISS, an international trio of astronauts and cosmonauts including NASA’s Shane Kimbrough departed the orbiting lab complex aboard their Soyuz capsule and plummeted back safely through the Earth’s atmosphere to a soft touchdown in Kazahkstan on Monday- as NASA meanwhile targets liftoff of the next US resupply ship a week from today.

These are busy times indeed with regular flights to low Earth orbit and back to maintain and enhance the scientific research aboard the multinationally built and funded million pound orbiting outpost.

ISS Expedition 50 came to a glorious end for Commander Shane Kimbrough of NASA and Flight Engineers Sergey Ryzhikov and Andrey Borisenko of the Russian space agency Roscosmos as they returned to Earth Monday, April 10 in Kazakhstan aboard their Soyuz spacecraft after spending 173 days aloft in the weightless environment of space.

The Russian Soyuz MS-02 capsule touched down safely by making a parachute assisted landing in Kazakhstan at approximately 7:20 a.m. EDT (5:20 p.m. Kazakhstan time).

The three person crew comprising Kimbrough, Ryzhikov and Andrey Borisenko landed southeast of the remote town of Dzhezkazgan in Kazakhstan.

Meanwhile as the trio were landing, NASA is targeting launch of the next commercial cargo ship for blastoff on April 18 with more than three tons of science and supplies to stock the station for the Expedition 51 crew.

Christened the ‘S.S. John Glenn’ to honor legendary NASA astronaut John Glenn – the first American to orbit the Earth back in February 1962 – the next Orbital ATK Cygnus cargo ship heading to the space station will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Liftoff of the S.S. John Glenn from NASA commercial cargo provider Orbital ATK on their seventh commercial resupply services mission to the ISS is slated for 11 a.m. EDT Tuesday, April 18.

John Glenn was selected as one of NASA’s original seven Mercury astronauts chosen at the dawn of the space age in 1959. He recently passed away on December 8, 2016 at age 95.

During their time in orbit, the Expedition 50 crew members contributed to hundreds of experiments in biology, biotechnology, physical science and Earth science aboard the world-class orbiting laboratory.

“For example, the Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. Results from this investigation could lead to the treatment of diseases and injury in space, and provide a way to improve stem cell production for medical therapies on Earth,” said NASA.

“The Tissue Regeneration-Bone Defect study, a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studied what prevents vertebrates, such as rodents and humans, from regenerating lost bone and tissue, and how microgravity conditions impact the process. Results will provide a new understanding of the biological reasons behind a human’s inability to regrow a lost limb at the wound site, and could lead to new treatment options for the more than 30 percent of the patient population who do not respond to current options for chronic, non-healing wounds.”

Kimbrough, Ryzhikov and Andrey Borisenko served as members of the Expedition 49 and 50 crews onboard the International Space Station during their 173 days in orbit.

During two flights Kimbrough has now amassed 189 days in space. During his two flights Borisenko now totals 337 days in space. Rookie Ryzhikov logged 173 days in space.

They leave behind another trio of crewmates who will continue as Expedition 51; namely NASA astronaut and new station commander Peggy Whitson, Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency).

The next manned Soyuz launch will carry just two crewmembers. Due to Russian funding cutbacks only 1 cosmonaut will launch. The crew comprises Jack Fischer of NASA and Fyodor Yurchikhin of Roscosmos. They are scheduled to launch Thursday, April 20 from Baikonur, Kazakhstan.

Russia Recruiting For Its Moon Bound Cosmonauts

Roscosmos has certainly come a long way in the past few decades. After facing an uncertain future in the 1990s, the federal space agency has rebounded to become a major player in space and a crucial partner in the International Space Station. And in the coming years, Roscosmos hopes to expand its reach further, with missions planned to the Moon and even Mars.

Towards this end, on Tuesday, March 14th, the agency announced that it is conducting a recruitment drive for new cosmonauts. All are welcome, the agency stressed, to apply to become the next-generation of space explorers (provided they meet the criteria). And if all goes as planned, a few lucky applicants will be the first members of the Russian space program to “fly to the Moon.”

Understandably, Roscosmos is hoping to jump start its space exploration program again and recapture the momentum it enjoyed during the Soviet Era. In addition to Sputnik and sending the first man and woman into space (as part of the Vostok program), the Soviet space program also produced a reusable spacecraft by the 1980s that was similar to the Space Shuttle (known as the Buran program).

Unfortunately, with budget cuts during this decade and the fall of the Soviet Union in 1991, several changes had to be made. For one, Roscosmos needed to turn to commercial satellite launches and space tourism in order to make up the difference in its funding. In addition, some observers have cited how Russia’s financial commitment to  the ISS has had a detrimental effect on other programs.

It is little wonder then why Russian wants to embark on some serious missions in the coming decades, ones which will reestablish it as a leader in space exploration. Intrinsic to this is a proposed crewed mission to the Moon, which is scheduled to take place in 2031. Roscosmos has also been developing the next-generation spacecraft that will replace the Soyuz-TMA, which has been the workhorse of the space program since the Soviet era.

Known as the the Federatsiya (Federation) capsule, this vehicle is scheduled to make its first crewed flight to space sometime in 2023 from the Vostochny cosmodrome in the Russian far east. As you can see from the images, it bears a striking resemblance to the Orion capsule. Unveiled at the 12th International Aviation and Space Salon in Moscow (MAKS-2015), this capsule will carry the first Russian cosmonauts to the Moon.

All they need now is fresh blood to make the journey. Hence why they are conducting their first recruitment drive in five years, which is the second drive to be is open to all people – not just military pilots, but also those working in the space industry. This time around, Roscosmos is looking for 6 to 8 new recruits who will train in how to fly the next-generation spaceships and make Russia’s long-awaited lunar landing.

As Sergei Kiralyov (Roscosmos’ Executive Director of Manned Programs) was quoted by RIA Novosti as saying, “There will be no discrimination based on skin colour or gender.” The criteria for these applicants include an age limit of 35, a height of between 1 m 50 cm – 1 m 90 cm (4’11” and 6’2″), and a weight of no more than 90 kilograms (~198 pounds).

The criteria also stress physical fitness, and claim that applicants must be able to cross-country ski for 5 km (~3 mi). They must also pass a series of psychological and physical tests (which include gynaecological examinations for women). In terms of skills, Roscosmos is seeking individuals who have an engineering degree, pilot training, experience in the aviation industry, and IT skills. Knowledge of a foreign language is also a plus (other than Russian, of course!).

“Recruitment of cosmonauts will take place starting from today, March 14, will take place before the end of the year. The results would be summed up in the end of December,” said Roscosmos’ First Deputy Director General Alexander Ivanov. Roscosmos also stressed that all those who are interested must apply by post or in person at the Star City astronaut training center outside Moscow (with three passport-sized photos included).

So if you speak Russian, are interesting in becoming part of the next-generation of cosmonauts, meet the requirements, or just want to go to the Moon, you might want to consider throwing your hat into the ring! Down the road, Roscosmos also has plans to conduct crewed missions to Mars between 2040 and 2060. These are expected to take place only after missions to the Moon are complete, which may include the creation of a lunar outpost.

A flawless shakedown mission from Russia’s newly modified Soyuz capsule successfully delivered a new multinational crew to the Space Station early Saturday, July 9 after a two day orbital chase.

The upgraded Soyuz MS-01 spacecraft launching on its maiden flight successfully docked to the International Space Station at 12:06 a.m. EDT Saturday, July 9, while soaring 254 statute miles over the South Pacific.

“Docking confirmed,” said a commentator from Russian mission control at Korolev outside Moscow. “Contact and capture complete.”

The Soyuz was ferrying the new multinational trio of astronauts and cosmonauts comprising Kate Rubins of NASA, Soyuz Commander Anatoly Ivanishin of the Russian space agency Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency on the Expedition 48/49 mission.

The three person crew of two men and one woman had launched flawlessly into picture perfect skies two days earlier from the Baikonur Cosmodrome in Kazakhstan at 9:36 p.m. EDT Wednesday, July 6 (7:36 a.m. Baikonur time, July 7), in the brand new version of the Russian Soyuz capsule that has been significantly upgraded and modified.

NASA’s Kate Rubins was strapped into the right seat, Ivanishin in the center and Onishi on the left.

It was a textbook approach on the shakedown mission that culminated in a flawless docking at the Earth-facing Russian Rassvet module on the Russian side of the massive orbiting outpost.

NASA TV carried the whole operation live with beautiful color video imagery streaming from the ISS showing the Soyuz approach and black and white video streaming from the Soyuz.

The Soyuz performed magnificently. All of the upgraded and modified systems checked out perfectly on this maiden flight of the new version of Russias venerable Soyuz, said NASA commentator Rob Navias.

“All new systems functioning perfectly,” said Navias. “This has been a perfect shakedown mission for the new Soyuz crew docking at the ISS.”

The Soyuz had slowed to an approach velocity of just 0.1 m/s at docking with the forward docking probe extended.

The approach was fully automated under Russian mission control as Ivanishin carefully monitored all spacecraft systems with steady update calls back to ground control.

The fully automated approached utilized the upgraded KURS NA automated rendezvous radar system.

During final approach, the Soyuz conducted a fly around maneuver starting at a distance of 400 meters. It moved 57 degress around the station while closing in to about 250 meters.

After station keeping for about 2 minutes while ground controllers conducted a final evaluation and no issues were detected, Russian mission control at last gave the GO for final approach and the GO command for docking was given.

The Soyuz made contact and completed a perfect docking at Rassvet. The hook and latches were then closed in for a tight grasp onto the station.

The crews then conducted a series of leak and pressurization checks.

After everything checked out, the hatches were finally opened about two and a half hours later at 2:26 a.m. EDT.

The new crew members of Expedition 48 officially floated aboard the International Space Station at about 2:50 a.m. EDT, July 9 with the hatches opened between their Soyuz MS-01 and the space station and after a live video transmission link had been established to show the festivities.

They were welcomed aboard with hugs and joined the Expedition 48 Commander Jeff Williams of NASA and Flight Engineers Oleg Skripochka and Alexey Ovchinin of Roscosmos.

With the arrival of Rubins, Ivanishin and Onishi, the stations resident crew is beefed up to its normal six person crew complement.

They soon held the traditional video telecon for well wishes and congratulations from family, friends and mission officials.

The new trio will spend at least four months at the orbiting lab complex conducting more than 250 science investigations in fields such as biology, Earth science, human research, physical sciences, and technology development.

Rubins is on her rookie space mission. She holds a bachelor’s degree in molecular biology and a doctorate in cancer biology which will be a big focus of her space station research activities.

The new trio will join Expedition 48 Commander Jeff Williams of NASA and Flight Engineers Oleg Skripochka and Alexey Ovchinin of Roscosmos.

“The approximately 250 research investigations and technology demonstrations – not possible on Earth – will advance scientific knowledge of Earth, space, physical, and biological sciences. Science conducted on the space station continues to yield benefits for humanity and will enable future long-duration human and robotic exploration into deep space, including the agency’s Journey to Mars,” says NASA.
The newly upgraded Soyuz offers increased reliability and enhanced performance.

Many changes were instituted including enhanced structural performance to minimize chances of micrometeoroid penetration. Engineers also added a fifth battery for more power and storage capacity. The solar arrays are also about one square meter larger and the efficiency of the solar cells increased about 2 percent.

Also a more modern command and telemetry system to interact with a new series of new Russian communications satellites that will offer greatly increased the coverage by ground control. This was previously only about 20 minutes per orbit while over Russian ground stations and will now increase up to 45 to 90% of orbital coverage via the Russian comsat system.

A phased array antenna was also added with increased UHF radio capability in the Soyuz descent module that now also include a GPS system to improve search and rescue possibilities.

The newly upgraded KURS rendezvous radar system will weigh less, use less power and overall will be less complicated. For example it doesn’t have to be moved out of the way before docking. Weighs less and uses less power.

New approach and attitude control thrusters were installed. The new configuration uses 28 thrusters with a redundant thruster for each one – thus two fully redundant manifolds of 28 thrusters each.
All of these modification were tested out on the last two progress vehicles.

Multiple unmanned cargo ships carrying tons of essential supplies and science experiments are also scheduled to arrive from Russia, the US and Japan over the next few months.

A SpaceX Dragon is scheduled to launch as soon as July 18 and an Orbital ATK Cygnus should follow in August.
The SpaceX Dragon CRS-9 mission is slated to deliver the station’s first International docking adapter (IDA) to accommodate the future arrival of U.S. commercial crew spacecraft, including the Boeing built Starliner and SpaceX built Crew Dragon.

A Japanese HTV cargo craft will carry lithium ion batteries to replace the nickel-hydrogen batteries currently used on station to store electrical energy generated by the station’s huge rotating solar arrays.

Two Russian Progress craft with many tons of supplies are also scheduled to arrive.

An international trio of astronauts and cosmonauts representing the United States, Russia and Japan blasted off in the early morning Kazakh hours today, July 7, for a new mission of science and discovery on the International Space Station (ISS).

The three person crew of two men and one woman launched flawlessly into picture perfect skies from the Baikonur Cosmodrome in Kazakhstan at 9:36 p.m. EDT Wednesday, July 6 (7:36 a.m. Baikonur time, July 7), and in a brand new version of the Russian Soyuz capsule that has been significantly upgraded and modified.

The launch of the Soyuz MS-01 spacecraft was carried live on NASA TV starting approximately an hour before the usual on time liftoff from Baikonur. The three stage Soyuz booster generates 930,000 pounds of liftoff thrust.

The trio comprises Kate Rubins of NASA, Soyuz Commander Anatoly Ivanishin of the Russian space agency Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency on the Expedition 48/49 mission.

They safely reached orbit at about 9:46 p.m. after the eight minute climb delivered them to the preliminary orbit of 143 x 118 mi. The Soyuz separated from the third stage and the solar arrays deployed as planned. NASA’s Kate Rubins was strapped into the left seat, Ivanishin in the center and Onishi on the right.

And precisely because it’s a heavily modified Soyuz, they will take the slow road to the ISS.

The crew will spend the next two days and 34 Earth orbits inside in order to fully check out and test the upgraded Soyuz spacecraft systems.

That’s in contrast to missions in recent years that took a vastly sped up 4 orbit 6 hour route to the space station.

Three carefully choreographed orbital adjustment burns will raise the orbit and propel the crew to the ISS over the next 2 days.

They expect to rendezvous and dock at the space station’s Russian Rassvet module at 12:12 a.m. EDT Saturday, July 9. After conducting leak and safety check they expect to open the hatch to the ISS at about 2:50 a.m. Saturday, July 9.
You can watch all the hatch opening action live on NASA TV with coverage starting at 2:30 a.m.

They will spend about four months at the orbiting lab complex conducting more than 250 science investigations in fields such as biology, Earth science, human research, physical sciences, and technology development.

KENNEDY SPACE CENTER, FL – NASA’s first ever ‘Year in Space’ astronaut Scott Kelly was in good shape and smiling broadly for the Earth bound photographers after safely returning to Earth from his orbiting home of the past year on the International Space Station (ISS), for a smooth touchdown in the steppes of Kazakhstan late Monday evening, March 1.

He soon jetted back to the USA for a grand arrival ceremony back home in Houston in the wee hours of the morning, today, March 3, 2016.

“Great to be back on Earth, said Kelly. “There’s no place like home!”

Kelly landed on US soil at Houston’s Ellington Field early this morning at about 2:30 a.m.

Kelly was welcomed back to the USA by Second Lady of the United States Dr. Jill Biden, Assistant to the President for Science and Technology Dr. John P. Holdren, NASA Administrator and former astronaut Charles Bolden, and Kelly’s identical twin brother and former NASA astronaut Mark Kelly.

Before departing the station after a 340 day stay, Kelly said that among the things he missed most on Earth were fresh air and food and freedom of movement. And swimming in his pool.

Well he quickly made good on those wishes and after arriving back home before daylight soon took a dip in his backyard pool.

Kelly posted a video of his pleasant pool plummet in all its glory on twitter:

“Man, that feels good!” he exclaimed.

The long trip back home began after Kelly boarded his Russian Soyuz TMA-18M return capsule along with Russian cosmonaut crewmates Mikhail Kornienko and Sergey Volkov.

Kelly and his Russian cohort Mikhail Kornienko comprised the first ever crew to live and work aboard the ISS for a record breaking year-long mission aimed at taking concrete steps towards eventually dispatching human crews for multiyear-long expeditions to the surface of Mars and back.

Volkov spent a normal six month increment aboard the station.

The goal of the 1 year ISS mission was to collect a variety of data on the effects of long duration weightlessness on the human body that will be used to formulate a human mission to Mars.

Kelly and Kornienko originally launched to the station on March 27, 2015 along with Russian crewmate Gennady Padalka.

The trio undocked from the station inside their cramped Soyuz capsule, pulled away, fired breaking thrusters and plummeted back to Earth a few hours later, surviving scorching reentry temperatures as the passed through the Earth atmosphere.

They safely landed in Kazakhstan at 11:26 p.m. EST on Tuesday night, March 1, 2016 (10:26 a.m. March 2 Kazakhstan time), concluding Expedition 46.

Kelly set an American record for longest time in space on a single mission by living and working for 340 days straight aboard the ISS.

Kelly and Kornienko share the history making distinction of comprising the first ever ‘1 Year Crew’ to serve aboard the massive Earth orbiting science research outpost in space.

With a cumulative total of 520 days in space, Kelly has amassed the most time for an American in space. Kornienko has accumulated 516 days across two flights, and Volkov has 548 days on three flights.

During the yearlong mission 10 astronauts and cosmonauts representing six different nations including the United States, Russia, Japan, Denmark, Kazakhstan and England lived aboard the space station.

The station currently remains occupied by a three person crew hailing from the US, Russia and England. A new three person crew launches later in March.

NASA’s next commercial resupply launch to the station is slated for March 22 by a United Launch Alliance Atlas V rocket carrying an Orbital ATK Cygnus cargo freighter with over 7000 pounds of fresh science experiments and crew supplies.

Congressional Slashes to NASA Commercial Crew Force Bolden to ‘Buy Russian’ rather than ‘Buy American’

US Congressional cuts to NASA’s commercial crew program forced NASA to buy more seats for US astronauts to launch on Russian Soyuz capsules like this one launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, July 22, 2015 EDT, rather than the American crew capsules under development by Boeing and SpaceX for NASA. Here the Soyuz TMA-17M capsule carries Expedition 44 Soyuz Commander Oleg Kononenko of the Russian Federal Space Agency (Roscosmos), Flight Engineer Kjell Lindgren of NASA, and Flight Engineer Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) into orbit to begin their five month mission on the International Space Station.

In the face of drastic funding cuts by the US Congress to NASA’s commercial crew program (CCP) aimed at restoring America’s indigenous launch capability to fly our astronauts to the International Space Station (ISS), NASA Administrator Charles Bolden is being forced to spend another half a billion dollars for seats on Russia’s Soyuz spacecraft instead of astronaut transport ships built by American workers in American manufacturing facilities.

The end effect of significantly slashing NASA’s Fiscal 2016 commercial crew budget request by both the US Senate and the US House is to tell NASA to ‘Buy Russian’ rather than to ‘Buy American.’

The $490 million of US taxpayer dollars will pay for six astronaut seats on the Soyuz manned capsule in 2018 and 2019 – that are now required due to uncertainty over whether the pair of new crewed transporters being built by Boeing and SpaceX for NASA will actually be available in 2017 as planned.

Furthermore the average cost per seat under the new contract with Russia rises to $81.7 million compared to about $76 million for the most recent contract, an increase of about 7 percent.

In response to the Congressional CCP budget cuts, NASA Administrator Bolden sent a letter notifying Congressional lawmakers about the agency’s new contract modifications with the Russian space agency about future crewed flights to the space station.

“I am writing to inform you that NASA, once again, has modified its current contract with the Russian government to meet America’s requirements for crew transportation services. Under this contract modification, the cost of these services to the U.S. taxpayers will be approximately $490 million,” Bolden wrote in an Aug. 5 letter to the leaders of the House and Senate committees responsible for deciding NASA’s funding.

The budget situation is completely inexplicable given the relentless pressure from Congress, led be Sen. John McCain, on the Department of Defense and US aerospace firm United Launch Alliance (ULA) to stop purchasing and using the Russian-made RD-180 engines for the 100% reliable Atlas V rocket by 2019 – as a way to punish Russian’s President Vladimir Putin and his allies.

Because on the other hand, those same congressional ‘leaders’ clearly have no hesitation whatsoever in putting money into Putin’s allies pockets via the NASA commercial crew account – at the expense of jobs for American workers and while simultaneously potentially endangering the ISS as a hedge against possible Russian launch failures. Multiple Russian and American rockets have suffered launch failures over the past year.

Boeing and SpaceX were awarded contracts by NASA Administrator Bolden in September 2014 worth $6.8 Billion to complete the development and manufacture of their privately developed CST-100 and Crew Dragon astronaut transporters under the agency’s Commercial Crew Transportation Capability (CCtCap) program and NASA’s Launch America initiative.

The purpose of CCP is to end our “sole reliance” on the Russian Soyuz capsule and launch US astronauts on US rockets and spaceships from US soil by 2017.

With CCP we would continue to work cooperatively with the Russians to everyone’s benefit – but not be totally dependent on them.

Under NASA’s CCtCAP contract, the first orbital flights of the new ‘space taxis’ launching our astronauts to the International Space Station had been slated to blastoff in 2017. But that schedule was entirely dependent on NASA’s ability to pay both aerospace companies as they made progress on completing the contacted milestones absolutely critical to achieving flight status.

Bolden had already notified Congress in February that the new contract modification would become necessary if Congress failed to fully fund the CCP program to enable the 2017 flights.

Since the forced retirement of NASA’s trio of shuttle orbiters in 2011, all American and ISS partner astronauts have been forced to hitch a ride on the Soyuz for flights to the ISS and back.

“Our plans to return launches to American soil make fiscal sense,” Bolden said recently. “It currently costs $76 million per astronaut to fly on a Russian spacecraft. On an American-owned spacecraft, the average cost will be $58 million per astronaut.”

Instead, the Obama Administrations 2016 request for commercial crew (CCP) amounting to $1.244 Billion was dealt another blow, and slashed to only $900 million and $1.0 Billion by the Senate and House committees respectively.

And this is just the latest in a lengthy string of cuts by Congress – which has not fully funded the Administration’s CCP funding requests, since its inception in 2010.

The budget significant budget slashes amounting to 50% or more by Congress, have already forced NASA to delay the first commercial crew flights of the private ‘space taxis’ from 2015 to 2017.

“Due to their continued reductions in the president’s funding requests for the agency’s Commercial Crew Program over the past several years, NASA was forced to extend its existing contract with the Russian Federal Space Agency (Roscosmos) to transport American astronauts to the International Space Station. This contract modification is valued at about $490 million,” said NASA.

So the net effect of Congressional CCP cuts has been to prolong US sole reliance on the Russian Soyuz manned capsule at a cost to the US taxpayers of hundreds of millions of dollars.

Indeed, given the crisis in Ukraine and recent Russian launch failures, one might think the Congress would eagerly embrace wanting to reduce our total dependence on the Russians for human spaceflight.

“Unfortunately, for five years now, the Congress, while incrementally increasing annual funding, has not adequately funded the Commercial Crew Program to return human spaceflight launches to American soil this year, as planned,” Bolden’s letter explains.

“This has resulted in continued sole reliance on the Russian Soyuz spacecraft as our crew transport vehicle for American and international partner crews to the ISS.”

“In 2010, I presented to Congress a plan to partner with American industry to return launches to the United States by 2015 if provided the requested level of funding.”

So if Congress had funded the commercial crew program, the US would have launched its first human crews on the CST-100 and crew Dragon to the ISS this year – 2015.

Bolden also repeated his request to work with the leaders of Congress in the best interests of our country.

“I am asking that we put past disagreements behind us and focus our collective efforts on support for American industry – the Boeing Corporation and SpaceX – to complete construction and certification of their crew vehicles so that we can begin launching our crews from the Space Coast of Florida in 2017.”

Currently, both Boeing and SpaceX are on track to meet the 2017 objective – but only if the CCP funds are restored.

Otherwise the contracts will have to be renegotiated and progress will be severely reduced – all at added cost. Another instance of pennywise and pound foolish.

“Our Commercial Crew Transportation Capability (CCtCap) contractors are on track today to provide certified crew transportation systems in 2017,” says Bolden.

“Reductions from the FY 2016 request for Commercial Crew proposed in the House and Senate FY 2016 Commerce, Justice, Science, and Related Agencies appropriations bills would result in NASA’s inability to fund several planned CCtCap milestones in FY 2016 and would likely result in funds running out for both contractors during the spring/summer of FY 2016.”

“If this occurs, the existing fixed-price CCtCap contracts may need to be renegotiated, likely resulting in further schedule slippage and increased cost.”

Overall, it’s just a terrible state of affairs for the future of US human spaceflight, as Congress once again places partisan politics ahead of the interests of the American people.

The fact is that the commercial crew space taxis from Boeing and SpaceX are the fastest, cheapest and most efficient pathway to get our astronaut crews to the Earth orbiting space station and back.

Common sense says we must restore our independent path to the ISS – safely and as quickly as possible.

How Do Astronauts Avoid Debris?

How Do Astronauts Avoid Debris?

So, just how do we keep our space stations, ships and astronauts from being riddled with holes from all of the space junk in orbit around Earth?

We revel in the terror grab bag of all the magical ways to get snuffed in space. Almost as much as we celebrate the giant brass backbones of the people who travel there.

We’ve already talked about all the scary ways that astronauts can die in space. My personal recurring “Hail Mary full of grace, please don’t let me die in space” nightmare is orbital debris.

We’re talking about a vast collection of spent rockets, dead satellites, flotsam, jetsam, lagan and derelict. It’s not a short list. NASA figures there are 21,000 bits of junk bigger than 10 cm, 500,000 particles between 1 and 10 cm, and more than 100 million smaller than 1 cm. Sound familiar, humans? This is our high tech, sci fi great Pacific garbage patch.

Sure, a tiny rivet or piece of scrap foil doesn’t sound very dangerous, but consider the fact that astronauts are orbiting the Earth at a velocity of about 28,000 km/h. And the Tang packets, uneaten dehydrated ice cream, and astronaut poops are also traveling at 28,000 km/h. Then think about what happens when they collide. Yikes… or yuck.

Here’s the International Space Station’s solar array. See that tiny hole? Embiggen and clarinosticate! That’s a tiny puncture hole made in the array by a piece of orbital crap.

The whole station is pummeled by tiny pieces of space program junk drawer contents. Back when the Space Shuttle was flying, NASA had to constantly replace their windows because of the damage they were experiencing from the orbital equivalent of Dennis the Menace hurling paint chips, fingernail clippings, and frozen scabs.

That’s just little pieces of paint. What can NASA do to keep Sandra Bullock safe from the larger, more dangerous chunks that could tear the station a new entry hatch?

For starters, NASA and the US Department of Defense are constantly tracking as much of the orbital debris that they can. They know the position of every piece of debris larger than a softball. Which I think, as far as careers go, would be grossly underestimated for its coolness and complexity at a cocktail party.

“What do you do for a living?”
“Me, oh, I’m part of the program which tracks orbital debris to keep astronauts safe.”
“So…you track our space garbage?”
“Uh, actually, never mind, I’m an accountant.”

Furthermore, they’re tracking everything in low Earth orbit – where the astronauts fly – down to a size of 5 cm. That’s 21,000 discrete objects.

NASA then compares the movements of all these objects and compares it to the position of the Space Station. If there’s any risk of a collision, NASA takes preventative measures and moves the Space Station to avoid the debris.

The ISS has thrusters of its own, but it can also use the assistance of spacecraft which are docked to it at the time, such as a Russian Soyuz capsule.

NASA is ready to make these maneuvers at a moment’s notice if necessary, but often they’ll have a few days notice, and give the astronauts time to prepare. Plus, who doesn’t love a close call?

For example, in some alerts, the astronauts have gotten into their Soyuz escape craft, ready to abandon the Station if there’s a catastrophic impact. And if they have even less warning, the astronauts have to just hunker down in some of the Station’s more sturdy regions and wait out the debris flyby.

The Iridium constellation – a robust satellite network (Iridium)

This isn’t speculation and overcautious nannying on NASA’s part. In 2009 an Iridium communications satellite was smashed by a dead Russian Kosmos-2251 military satellite. The collision destroyed both satellites instantly. As icing on this whirling, screaming metallic orbital-terror-cake, it added 2,000 new chunks of debris to the growing collection.

Most material was in a fairly low orbit, and much of it has already been slowed down by the Earth’s atmosphere and burned up.

This wasn’t the first time two star-crossed satellites with a love that could-not-be had a shrapnel fountain suicide pact, and I promise it won’t be the last. Each collision adds to the total amount of debris in orbit, and increases the risk of a run-away cascade of orbital collisions.

We should never underestimate the bravery and commitment of astronauts. They strap themselves to massive explosion tubes and weather the metal squalls of earth orbit in tiny steel life-rafts. So, would you be willing to risk all that debris for a chance to fly in orbit? Tell us in the comments below.
