Russian government going broke

4:54 pm

The Russian government, faced with low oil prices, a weak ruble, and a big budget, has been depleting its cash reserves and could run out of money within a year.

The government’s reserve fund is designed to cover shortfalls in the national budget at times of low oil and gas revenues.

Russia’s 2016 budget is based on the assumption the country would be able to sell its oil for $50 per barrel. But the average oil price in the first eight months of the year was less than $43 per barrel. Oil now makes up just 37% of all government revenues, compared to roughly 50% just two years ago.

When their reserve funds run out, they will then dip into another fund reserved for pensions and investment projects. Sounds familiar, doesn’t it? Kind of like the approach the big Democratically controlled U.S. cities like New York have used to continue to spend money they didn’t have.

It is interesting to compare Russia and China these days, especially considering the state of both of their space programs. Despite the fact that many say that China’s success is hollow, they have still been able to fund and build what is now a very vibrant and new manned and planetary space effort. Russia however cannot build anything new, and is now faced with reducing its ISS crew complement because it can’t afford to launch the supplies required for three people.

It will be very interesting to watch this story in Russia unfold.

Russian ISS crews to be reduced beginning in spring 2017

12:20 pm

Russia today made it official: Beginning in the spring of 2017 their crews to ISS will be reduced from 3 to 2, and will remain reduced until they launch their next ISS module.

“In case the endorsed schedule is observed and the MLM gets into operation in December 2017, the curtailment will affect only one Russian crew,” the source said. “Otherwise the practice of curtailment will continue until the commissioning of the module.”

The Russian state space corporation Roscosmos has to downsize the ISS mission crew as the number of Progress cargo ships launched to the ISS annually will be reduced to three from four at present in the wake of NASA’s refusal to continue using the Progresses and to change over to new U.S. cargo carriers instead, the source said, adding that three Progresses a year is not enough to support three cosmonauts working at the ISS permanently.

The finances will get even more squeezed when the U.S. no longer needs them to launch its astronauts.

Budget constraints and technical challenges delay commercial crew

10:56 am

A NASA inspector general report released today cites both budget constraints imposed by Congress as well as technical challenges that will delay the first commercial manned mission to ISS until 2018.

When the commercial crew program began, NASA hoped to have routine flights by 2015, but that slipped in large part due to congressional underfunding in the early years. OIG noted today that its 2013 report found that adequate funding was the major challenge for the program. Congress has warmed up to the program, however, and now is approving the full President’s request so funding is not the issue it once was. Technical challenges now are the major hurdle according to today’s report.

The companies’ systems must be certified by NASA before beginning routine flights to ISS. Boeing anticipates receiving certification in January 2018 with its first certified flight in spring 2018, and SpaceX is working toward late 2017 for its first certified mission, the OIG report says. But it is skeptical: “Notwithstanding the contractors’ optimism, based on the information we gathered during our audit, we believe it unlikely that either Boeing or SpaceX will achieve certified, crewed flight to the ISS until late 2018.”

The report has been written prior to yesterday’s Falcon 9 launchpad failure, which will certainly impact the schedule negatively.

Essentially, the report claims that the program was delayed initially by about two to three years because of the refusal of Congress to fund it fully. The delays to come will be instead because of the technical challenges. While I tend to agree with this assessment, I also note that government reports like this are often designed to generate more funds for the agencies involved, not find a better way to do things. If we are not diligent and hard-nosed about how we fund this program I worry that with time commercial crew will become corrupted by the government’s sloppy and inefficient way of doing things, and become as bloated as Orion and SLS. This is one of the reasons I never complained when Congress short funded the program previously, as it forced the companies involved to keep their costs down.

DNA sequencing successfully done on ISS

8:56 am

Researchers have now confirmed that a new lightweight DNA sequencer has been successfully tested on ISS.

Using a hand-held, USB-powered sequencing device called the MinION, astronaut Kate Rubins, PhD, sequenced samples of mouse, bacteria and virus DNA. This portable sequencing technology could eventually help diagnose sick astronauts, monitor space station food, water, and environment for microbes, and identify extraterrestrial life forms.

As part of a collaboration with NASA on the Biomolecular Sequencer project, Earth-bound researchers – a bicoastal team at UCSF and Weill Cornell Medical College – analyzed the sequencing data from space and compared it to identical samples sequenced on the ground. The analysis would tell whether the journey to space and conditions aboard the space station affected the sequencing results.

…[An] analysis of the space and Earth data found comparable results. “We essentially got equivalent data, and it’s of very high quality, probably within the top 20 percent of nanopore runs that we do routinely here on Earth,” Chiu said.

The press release makes a big deal about how this new equipment will be beneficial for research in space, but I am betting that its creators are as much if not more interested in the profits they will make selling it to customers on Earth, where its portability will make a very useful and beneficial to Earth-bound patients and researchers.

Dragon splashes down

6:24 pm

The competition heats up: SpaceX’s most recently launched Dragon capsule today returned to Earth and was successfully recovered.

The Dragon is the only spacecraft flying today that can return large amounts of cargo to Earth.

Among the cargo brought back from space Friday were a dozen mice from a Japanese science experiment — the first brought home alive in a Dragon. Samples from mice euthanized as part of an experiment by pharmaceutical company Eli Lilly also were on board. Results were returned from an experiment that studied the behavior of heart cells in microgravity, and from research into the composition of microbes in the human digestive system, NASA said. Findings from both could help keep astronauts healthy during deep space exploration missions.

Russia reveals its proposed new cargo spacecraft

8:57 am

Government vaporware: In an effort to save money Russian engineers have designed a new cargo spacecraft to replace the Progress freighter.

Faced with latest economic problems, and the need to reduce the number of Progress cargo launches, Russia’s space agency Roskosmos made plans to cut the permanent crew of ISS cosmonauts from three to two people. However the full international crew on the ISS is supposed to include six people with half of it reserved for Russia.

To resolve this supply problem, Roskosmos ordered RKK Energia, its key contractor responsible for human spaceflight, to prepare a preliminary design of a bigger cargo ship by the end of this month. Engineers quickly put together this proposal that would combine off-the-shelf hardware with new technology. … The most important new feature of the proposed cargo ship will be the six-tank cluster to carry more than 1.8 tons of propellant to the station. It will simultaneously serve as a tanker for the space station while also feeding the ship’s own propulsion system. As a result, the new design provides significant mass savings in comparison to the current Progress ships, which need two separate sets of tanks for refueling and maneuvering.

The main engine for the new cargo ship will be borrowed from an existing satellite. Meanwhile, 28 small thrusters for orbit correction and maneuvering will be copied practically unchanged from the Progress.

They hope to fly this new freighter by 2020. I’m willing to bet anyone that this won’t happen.

Russia’s space station faces funding problems

10:11 am

The Russian space station replacement for ISS, dubbed the Russian Orbital Station (ROS), faces serious budget problems that might delay its launch.

Plans for the post-ISS Russian Orbital Station, ROS, are in limbo, as the nation’s space program has faced budget cuts in 2016. Although the industry has now completed formulating the overall design of the future station, the cash-strapped Roskosmos was yet to approve the formal technical assignment for the development of ROS as of June 2016. The addendum to the Federal Contract, which would fund further development work on the project, has not been issued either.

The ROS project stalled despite being formally approved by three strategy documents governing the current Russian space program: The 10-year Federal Space Program from 2016 to 2025, known as FKP-2025; The Strategy for Russian Piloted Space Flight until 2035 and the Concept of the Russian Piloted Space Flight.

The article also provides a nice overview of how Russia hopes to assembly ROS, partly from new modules and partly from modules they will detach from ISS. The article also made this key point:

According to the current ROS concept, the new Russian station will have a truly unlimited life span, thanks to the possibility to replace any of its modules. (It is practically impossible with the current ISS architecture.) The new Russian station is also designed to operate either as a permanently inhabited outpost or as a periodically visited facility. Russian strategists also hope that the new station will inherit the international nature of the ISS project.

I think Russia is beginning to see the operation of Earth orbital space stations as a profitable niche they can occupy. They know how to do it and already have the technology on hand, and can do it at very affordable prices. Whether they can afford it themselves, however, remains an open question.

Russia considers reducing its ISS crew

9:43 pm

In the heat of competition: Russia is considering reducing its ISS crew from three to two.

“Plans to reduce the crew stem from the fact that less cargo ships are sent to the ISS and from the necessity to boost the efficiency of the program,” the newspaper quotes Krikalev. Apart from that, it will make it possible to lower expenses on the space station’s maintenance.

They haven’t yet made a decision. I suspect that the real reason they are considering this idea is because it will free up a seat on the Soyuz spacecraft that they can then sell to tourists, something they have been unable to do since the station got large enough for the full crew of six and the U.S. became dependent on them for crew ferrying.. By only sending two Russians astronauts up with each Soyuz launch they will then have a free seat for short tourist flights, which had been quite lucrative for them.

Orbital ATK delays Antares-Cygnus launch until September

9:36 am

In the heat of competition: Orbital ATK has once again pushed back the launch of the first upgraded Antares rocket since its launch failure in October 2014, this time until September.

Due to a variety of interrelated factors, including the company’s continuing processing, inspection and testing of the flight vehicle at Wallops Island, and NASA’s scheduling of crew activities on the International Space Station in preparation for upcoming cargo and crew launches, Orbital ATK is currently working with NASA to target a window in the second half of September for the launch of the OA-5 mission. A more specific launch date will be identified in the coming weeks.

This press release suggests that all is well, and that the delay is mostly because of scheduling issues with NASA and ISS. However, it is also very vague, which suggests to me that the company has been also working through the results of the static fire test they did in May and might have needed more time to work out the kinks..

Reused Dragon cargo capsule to ISS within a year

4:05 pm

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

Toilet failure on U.S. segment of ISS

11:14 pm

According to this report, the American-built toilet on the U.S. part of ISS has broken down.

The story has few details, and is based on anonymous sources. Nonetheless, I suspect it is true, as the American toilet has had problems in the past, was originally designed for easy transport up and down from ISS on the space shuttle, and is thus difficult to repair in space.

Vision problems from weightlessness

6:03 pm

This article provides an excellent review of the vision problems caused by long term exposure to weightlessness, including the efforts to study the problem on Earth.

Bottom line:

Before a human trip to Mars — a journey of six-to-nine months that NASA says it wants to achieve by the 2030s — researchers agree that VIIP [the name given to this problem] must be understood much better. VIIP could be the first sign of greater dangers to the human body from microgravity. “We’re seeing the visual and neural, ophthalmic manifestations of it,” Barratt said. “I’m fairly certain this is a bit more global than that.”

Richard Williams, the chief health and medical officer at NASA, agrees that what we do not know about VIIP still poses the biggest threat. Ironically, one of the only ways to get more knowledge is spend more time in microgravity. “The longer we stay in space, the more we’re going to learn,” Williams said.

A Russian space station spun off from ISS?

10:06 pm

The competition heats up: Energia, Russia’s main contractor for building its part of ISS, has proposed a plan to separate the Russian modules from ISS, once they are finally launched, to create a new and solely Russian space station.

According to RKK Energia, the prime Russian contractor on the ISS, the new outpost would begin with the separation of the Nauka [Russia’s ISS science module, long delayed] from the rest of the old station in mid-2020s. By that time, Nauka should have two even newer modules in tow. One would be the so-called Node Module, a tinker-toy-like component that could connect to six other modules, crew ships, cargo tankers, structural elements, you name it. The Node Module is already in RKK Energia’s garage and ready to go within a few months after the Nauka.

Next would be the new Science and Power Module (NEM) which, as it name implies, will finally give cosmonauts a state-of-the-art science lab and a pair of large solar arrays, making the Russian segment fully independent from the rest of the ISS in terms of power, communications, and other resources. The launch of NEM, currently promised as early as 2019, would set the stage for these three components to leave the ISS to form ROS.

Russia has always given itself the option to do this, designing its part of the station in a way that would allow it to stand alone.

SpaceX’s first stage teaches them how to land on Mars

9:56 am

The competition heats up: This update on the status of SpaceX’s manned Dragon capsule also provides this interesting detail about the engineering knowledge gained from the company’s effort to vertically land its Falcon 9 first stages:

The company is also using the propulsive landings as a way to practically and physically test landing systems in a near-Mars atmospheric environment. “Earth’s upper atmosphere is also a really good analogue for Mars’ atmosphere,” noted [Garrett Reisman, Director of Space Operations]. “When you get up high enough, the density and consistency of the atmosphere is very similar to what you face during Entry, Descent, and Landing (EDL) on Mars. So every time we land, we take one of these rockets and we perform hypersonic retrograde propulsion, the data from which we’re sharing with JPL because it’s the first time this has ever been demonstrated on a major scale.”

To this end, Reisman pointed out that the Falcon 9 first stage landings are really serving as test beds for the EDL systems of eventual Mars missions. “Every time you see one of those rockets coming back, not only is it enabling a whole new paradigm for launching things into space, but it’s also bringing us one step closer to Mars.

As for Dragon, it now appears the company wants to do a full unmanned demo flight to and from ISS before it performs its launch abort test. They will then follow this with a manned demo mission to ISS. All three flights are planned for 2017.

Kelly describes medical issues from weightlessness

8:50 am

In prepared remarks to a congressional subcommittee today, astronaut Scott Kelly described the medical problems he has experienced since returning from his 340 day mission on ISS.

Kelly claimed in these remarks that weightlessness caused permanent effects (which this news article decides to emphasize), but I think that might be an overstatement. None of the specific problems he experienced appear to be permanent ones, and in my interviews with Russian astronauts who stayed even longer on Mir they noted no permanent effects. One did say however that the recovery time tended to match the mission time, so that if you spent a year in space it took a year to completely recover. Kelly has only been back about three months, so his recovery is certainly not over yet.

Update: Kelly’s remarks were part of a hearing promoting legislation that would give astronauts lifetime medical coverage from the government. Thus, there is a bit of lobbying going on here.

Cygnus to depart ISS, then start a fire

5:40 pm

A fire in space: Orbital ATK’s Cygnus capsule is scheduled to leave ISS on Tuesday, when shortly thereafter it will begin a controlled fire experiment.

“Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions. – See more at: http://www.space.com/17933-nasa-television-webcasts-live-space-tv.html#sthash.2DjFjJqY.dpuf

The departure is scheduled for 9 am (eastern), and will aired live by NASA.

Boeing begins assembling second Starliner manned capsule

9:05 am

The competition heats up: With the arrival of the major capsule components to Boeing’s Florida facility the company has begun assembly of its second Starliner manned capsule.

Following closely behind the joining of the two major hull components for the Structural Test Article (STA) of the CST-100 Starliner, Boeing and NASA are marking the arrival of the upper dome, one half of the Starliner pressure vessel, for the second Starliner module. The three components will undergo separate outfitting operations in the Commercial Crew and Cargo Processing Facility (C3PF) where wiring lines, avionics and other systems will be installed and tested before the pieces are connected to form a complete Starliner.

This second Starliner module is known to Boeing as Spacecraft 1. Once completed inside C3PF, Starliner Spacecraft 1 will be outfitted with electrical and fluid systems before engineers will attach the outer thermal protection shielding and the base heat shield that will eventually protect crewmembers during re-entry. Starliner Spacecraft 1 will be used in the pad abort test to validate that the launch abort system will be able to lift astronauts away from danger in the event of an emergency during launch.

The article provides good detail about the upcoming Starliner test schedule.

Russia delays next manned Soyuz flight

5:45 pm

Russia has confirmed previous reports and has officially delayed the next manned Soyuz launch to ISS from June 24 to July 7.

They remain vague about the issue causing the delay, this time only saying they want more time to test software. Previous reports suggested the issue was with the capsule’s control thrusters.

Meanwhile, no word on whether they have figured out why the upper stage on the previous Soyuz rocket launch shut down prematurely.

Astronauts enter privately built BEAM module

8:59 am

Led by American Jeff Williams, two astronauts opened the hatch and entered Bigelow’s BEAM inflatable module on ISS today.

Williams officially opened the hatch at 08:47 UTC. Along with Russian cosmonaut Oleg Skripochka, Williams entered BEAM for the first time to collect an air sample and begin downloading data from sensors on the dynamics of BEAM’s expansion. The astronaut reported that the interior of BEAM looks “pristine”. However, he added the temperature was on the cool side – with Houston adding they recorded 44F as the temperature at bulkhead – but no condensation was visible. He then took air samples, as is the procedure for entering a new module.

They will install interior sensors over the next two days, and then shut the hatch. The module will then remain closed for most of its planned two year stay on ISS to test its operation in space.

The article also includes some nice details about the possible uses of Bigelow’s much larger B330 modules, two of which are under construction right now.

Manned Soyuz launch delayed

3:50 pm

More Russian quality control issues? The next manned launch to ISS has been delayed for a week because of an issue with the capsule’s control thrusters.

The article is lacking in any details, though it appears that the Soyuz capsule’s system for controlling its roll is the source of the problem. This issue, on top of the fact that the most recent Soyuz rocket launch last week had an unexplained premature engine shutdown, should make everyone a bit nervous about the reliability and safety of the Russian manned system.
