Falcon 9 first stage returns to port

8:34 am

The competition heats up: The recovered first stage of last week’s Falcon 9 launch has returned to port, and is being prepared for tests and eventual reflight.

The Falcon 9’s destination is unconfirmed, but SpaceX chief executive Elon Musk said Friday the rocket’s first stage will likely go to launch pad 39A — a former shuttle launch facility now leased by SpaceX — for a series of engine firings to verify its flight readiness.

The objective: Fly the first stage booster again, perhaps as soon as June. “We’re going to do a series of test fires,” Musk told reporters after Friday’s launch. “We’re hoping to do that at the Cape, rather than transport it to Texas (SpaceX’s rocket test facility), and then bring it back. Our plan is to basically fire it 10 times in a row on the ground. If things look good at that point, then it’s qualified for reuse and launch. We’re hoping to re-launch on an orbital mission in … June.”

SpaceX already has one customer, satellite-maker SES, quite eager to pay the discounted price to fly one of its satellites on this booster.

ULA to launch two Bigelow space station modules

8:22 am

The competition heats up: ULA and Bigelow Aerospace have announced a partnership to launch two of Bigelow’s largest space station modules, each with about as much interior space as both Skylab and Mir.

Both will be ready for launch by 2020. Neither company has made clear if they have any outside investment, though they left open the option of working with NASA and having the modules attached to ISS.

Dragon arrives at ISS

9:06 am

The competition heats up: SpaceX’s Dragon capsule has been berthed with ISS, bringing with it Bigelow’s privately built inflatable test module.

This berthing also makes it the first time the two American cargo freighters, Dragon and Cygnus, are docked at ISS at the same time.

In a related non-news story, the head of Russia’s space agency Roscosmos, which now controls that country’s entire aerospace industry, claimed in a television interview today that Russia is the world’s “undisputed leader … in launch vehicles and launch services,” noting that they launch about 40% of all launches worldwide.

That’s nice for him to say, but just because you say it doesn’t make it so. I expect that 40% number (which includes all Russian government launches and is thus inflated from their actual market share) to shrink considerably in the coming years, as the Russian space industry has shown a complete inability to innovate in the last twenty years. With the consolidation of that industry into a single corporation all run by the government, I do not expect that inability to go away anytime soon.

Video of Falcon 9 first stage barge landing

10:57 am

This is so incredible to watch that I must post it on the webpage. I think I’ve already seen it a dozen times, and still cannot get over how the rocket, coming in fast and on an angle, rights itself, lands, bounces slightly, and then settles upright into place.

The future here is rushing up on us, fast, in the best way possible.

Next Atlas 5 launch delayed indefinitely

9:33 am

In the heat of competition: Because of the continuing investigation into the launch issue during its last launch, ULA has now extended the delay of the next launch of its Atlas 5 from one week to an indefinite delay.

The report at the link is very brief, and it also does not give a source. I was not able to find any other reports of this story after doing a web search as well as a search of ULA’s website, so it remains unconfirmed. Nonetheless, I suspect it is real, suggesting the company has uncovered some unexpected issue with the Atlas 5 that now requires more serious action that is going to take time. Stay tuned.

Kepler in trouble

9:29 am

Engineers report that the Kepler space telescope went into safe mode about two days ago.

During a scheduled contact on Thursday, April 7, mission operations engineers discovered that the Kepler spacecraft was in Emergency Mode (EM). EM is the lowest operational mode and is fuel intensive. Recovering from EM is the team’s priority at this time.

The mission has declared a spacecraft emergency, which provides priority access to ground-based communications at the agency’s Deep Space Network. Initial indications are that Kepler entered EM approximately 36 hours ago, before mission operations began the maneuver to orient the spacecraft to point toward the center of the Milky Way for the K2 mission’s microlensing observing campaign.

This brief report does not look good. If the spacecraft is in a “fuel intensive” mode, it means it is using extra fuel to survive. This suggests that if they don’t recover it soon it might run out of the fuel and be lost forever.

ULA trims workforce

9:25 am

The competition heats up: In an effort to cut its costs, ULA has announced that it is laying off 375 workers.

The job cuts are not because the company is having financial troubles, but because they need to lower their launch prices to compete with SpaceX.They have always had some fat that could be trimmed but have not done so because, before SpaceX, there was no effort in the launch industry to cut costs. SpaceX, and some good healthy competition in a free market, is now forcing this upon everyone.

SpaceX lands its first stage on a barge

1:56 pm

The competition heats up: SpaceX has for the first time successfully landed the first stage of its Falcon 9 rocket on a barge, even as it has successfully launched Dragon to ISS.

Go here to see the stage on the barge, even as I type. More here, including images.

That makes two first stages recovered, suggesting that this is going to become increasingly routine for the company. Now comes the next big step, using one of these used stages a second time to launch another satellite.

Phase 2 begins in DARPA spaceplane program

8:59 am

The competition heats up: DARPA is about to start asking for proposals for the second phase of its XS-1 spaceplane program.

In Phase 1 of XS-1, DARPA sought to evaluate the technical feasibility and methods for achieving the program’s goals. To achieve that, it awarded prime contracts to three companies, each working in concert with a commercial launch provider: The Boeing Company (working with Blue Origin, LLC); Masten Space Systems (working with XCOR Aerospace); and Northrop Grumman Corporation (working with Virgin Galactic). Phases 2 and 3 will be competed as a full and open Program Solicitation mandating an Other Transaction Authority (OTA) agreement with the expectation of a single resulting award. Cost share is expected.

The primary goal is to build a vehicle that can fly ten times in ten days and put a small satellite into orbit.

Update on Dawn at Ceres

10:07 am

Link here. Though the story initially focuses on the possibility that the mission might be extended a few extra months until the spacecraft’s fuel runs out, it also gives a good summary of what has been learned so far about the dwarf planet, including the theory that Ceres was once an “ocean world.”

[Carol Raymond, Dawn’s deputy principal investigator,] said Ceres appears to be a former ocean world and could have once been similar to Europa or Enceladus, the icy moons of Jupiter and Saturn. “One of the things that we anticipated about Ceres before getting there is that it’s a former ocean world,” Raymond said. “We’re so interested in going to Europa and Enceladus, and these other interesting objects in the outer solar system because we think they harbor subsurface oceans at present, and possible habitable environments, and possibly even locations where there’s extant life.

“Ceres appears to have been one of those objects in the past, when it was younger and hotter,” Raymond said. “What we’re looking at now is, we believe, the remnant of a frozen ocean. The salt is left over from the brines that were concentrated as the ocean froze out, so it’s all a fairly consistent story that Ceres is a former ocean (world) where the ocean froze, and now we’re interrogating the chemistry, essentially, of that ocean-rock interface through the subsurface layers that we’re detecting on Ceres.”

The data has found the high latitudes to have lots of hydrogen, suggesting water-ice on or near the surface. The bright salt patches also suggest frozen water below the surface that left behind the salt when it reached the surface and evaporated away.

NASA picks Aerojet Rocketdyne engine for SLS upper stage

9:49 am

Government in slow motion: Only six years after program start, NASA has finally chosen Aerojet Rocketdyne’s legacy RL10 rocket engine for the upper stage of the SLS rocket.

The RL10 is an expander cycle liquid hydrogen/liquid oxygen rocket engine typically used on upper stage applications. It was first developed by Pratt & Whitney in the late 1950s and first flown in 1963. It has flown on hundreds of launches, logged approximately 15,000 hot fires, and accumulated more than 2.3 million seconds of hot fire operation time with a demonstrated reliability ratio greater than 0.999 throughout its history. The RL10 – which is used in various forms with Atlas’ Centaur Upper Stage (RL10A-4-2) and Delta IV’s Upper Stage (RL10B-2) – has a history back to the Saturn I’s S-IV Stage.

No other engine exists that can be built in time. Even so, the engine will not be ready for the first SLS launch tentatively scheduled in 2018, but will instead be used on the next two flights. The article also indicates that NASA is planning to delay SLS’s second flight two years to 2023, creating a five year gap which they will use to integrate the RL10 into SLS, while also rebuilding the mobile platform used to move SLS to the launchpad. (For some reason, the reconfiguration installed for the first SLS flight won’t work for later flights.)

The delay to 2023 has not been announced officially, but I have seen too much evidence recently, including statements in this GAO report, that tells me the delay is certain. Furthermore, it seems increasingly likely that the second flight will also be unmanned, and it won’t be until the third flight (as yet unfunded by Coingress) that humans will finally fly on SLS.

The cost? I am doing an analysis of this subject right now for a policy paper I am writing for a Washington think tank, and my preliminary estimate exceeds $41 billion for NASA to fly just one manned flight of SLS. That’s a bit more expensive than the $10 billion NASA is paying SpaceX, Orbital ATK, and Boeing to launch more than a dozen cargo freighters and as many as a dozen manned flights to ISS.

For those elected officials out there who have trouble with math, let’s compare again:

  • SLS: $41 billion for one flight, 15 years development to first flight.
  • Commercial space: $10 billion for two dozen flights, 5 years development to first flight.

Which costs less and gives more bang for the buck? Can you figure that out, Congressmen and Senators? If you need help I can provide you a few more fingers so you can count above ten.

The changing color of Comet 67P/C-G

9:12 am

Data from Rosetta has found that Comet 67P/C-G has changed color and brightness since the spacecraft’s arrival.

Even when Rosetta first rendezvoused with the comet far from the Sun, ices hidden below the surface were being gently warmed, sublimating into gas, and escaping, lifting some of the surface dust away and contributing to the comet’s coma and tail. VIRTIS shows that as the ‘old’ dust layers were slowly ejected, fresher material was gradually exposed. This new surface was both more reflective, making the comet brighter, and richer in ice, resulting in bluer measurements.

On average, the comet’s brightness changed by about 34%. In the Imhotep region, it increased from 6.4% to 9.7% over the three months of observations

The changes are similar to those found on the Moon when the surface there is disturbed. The old surface is very dark. When hit by a meteorite or scrapped by an astronaut’s foot, it brightens. In the case of Comet 67P, the underlying ice pushes outward when heated, the dust is removed, and the surface gets brighter.

Smallsat company searches for launch services

9:04 am

The competition heats up: Terra Bella, formally known as Skybox Imaging, hopes to have as many as 21 satellites in orbit by the end of 2017.

Space Systems Loral (SSL) is Terra Bella’s manufacturing partner for the SkySat satellites, building 19 SkySat Cs — one prototype and 18 final versions. Joe Rothenberg, director of Skybox engineering and operations at Google, told Via Satellite that the first SkySat C satellite is currently scheduled to launch aboard a Polar Satellite Launch Vehicle (PSLV) from the Indian Space Research Organization (ISRO) on May 31. The PSLV launch is for the prototype to precede the rest of the series. The next four are then to launch on an Arianespace Vega as a rideshare this summer, followed by six more on Orbital ATK’s Minotaur rocket during the fourth quarter this year.

The Skybox C satellite only weights 265 pounds, so it is larger than a cubesat but tiny compared to most commercial satellites. The company’s problem now is that, except for Orbital ATK’s Minotaur rocket, they don’t have a launch vehicle dedicated to this size satellite. And Minotaur is probably too expensive (which is why Orbital wants the right to use surplus ICBM motors to power it). Because of this Terra Bella must launch its satellites as secondary payloads, which leaves them at the scheduling mercy of the primary payload. Virgin Galactic’s LauncherOne is intended to serve this smallsat market, competing directly with Minotaur, but Terra Bella is understandably skeptical of that company’s effort.

A small piece of trivia. Rothenberg was a key NASA manager running the shuttle Hubble repair missions, one of the few NASA efforts that operated like a private company: competitive, hard-working, and demanding of success. It is entirely fitting that he has moved out of the government and into the private sector, where his skills can truly shine. It speaks well of Terra Bella that they hired him.

Ariane 6 delayed by tax and legal issues

5:35 pm

In the heat of competition: Even as Airbus Safran claimed today that Ariane 6 will be price competitive with SpaceX’s Falcon 9, the company cannot begin work on the new rocket because of a turf war Arianespace and French tax collectors.

The tax issue is as follows:

Airbus and Safran had agreed that Safran would pay Airbus 800 million euros ($874 million) in cash, in addition to its rocket-engine manufacturing capability, to become a 50-50 ASL shareholder with Airbus. Airbus officials since the beginning of the year have been negotiating with French tax authorities to determine how to minimize the tax bite of the cash transfer, which industry officials could be as high as 500 million euros, leaving Airbus with a net of just 300 million euros.

Delays in the cash transfer have meant that ASL, which is expected to count 8,000 employees, has been operating with only around 400 employees. In addition, it has made it difficult for the initial ASL team to present a fixed-price Ariane 6 production proposal to the 22-nation European Space Agency, which is financing the majority of Ariane 6 development.

In addition, the merger is being reviewed by the European Commission, part of the European Union.

The commission is looking at whether Arianespace’s minority shareholders, who are Ariane 6 contractors, will be protected once Airbus Safran Launchers raises its Arianespace shareholding to 74 percent from today’s 39 percent. The commission is also reviewing concerns expressed by satellite builders that Airbus, which is a major manufacturer of commercial satellites, might give its own satellites preferential treatment in setting the Ariane 6 manufest.

Airbus Safran still insists they can get the new rocket launched by 2020, but somehow that doesn’t seem reasonable to me, especially because I expect the French and European government authorities here to carve out their piece of the action, thus making it harder for the private company to deliver on time.

WISE completes another year of asteroid hunting

9:08 am

After being mothballed in space and then reactivated, NASA’s WISE infrared telescope (renamed NEOWISE for no good reason) has now completed its second year of observations, looking for near-Earth objects (NEOs).

NASA’s Near-Earth Object Wide-field Survey Explorer (NEOWISE) mission has released its second year of survey data. The spacecraft has now characterized a total of 439 NEOs since the mission was re-started in December 2013. Of these, 72 were new discoveries. Near-Earth Objects (NEOs) are comets and asteroids that have been nudged by the gravitational attraction of the giant planets in our solar system into orbits that allow them to enter Earth’s neighborhood. Eight of the objects discovered in the past year have been classified as potentially hazardous asteroids (PHAs), based on their size and how closely their orbits approach Earth. [emphasis mine]

Unfortunately, the press release does not provide any details about those eight potentially hazardous asteroids.

India to test reusable mini-shuttle in May

8:56 am

The competition heats up: ISRO, India’s space agency, this week announced plans to conduct its first test flight of its half-scale prototype reusable launch vehicle in May.

The RLV, is a scaled-down prototype (some 21.3 feet in length or 6.5 meters) of a future uncrewed single-stage reusable spaceplane, known as Avatar, that is being designed by the ISRO. The May mission will be a technology demonstrator (RLV-TD) to test powered cruise flight, autonomous landing and hypersonic flight using an air-breathing propulsion system. The spacecraft, which resembles a small winged aircraft, will be launched from the first launchpad of the Satish Dhawan Space Centre to an altitude of 43 miles (70 km) atop a two-stage Rohini sounding rocket and then released. It will re-enter the atmosphere and travel back to Earth in a controlled descent, to be recovered from the Bay of Bengal. [emphasis mine]

This vehicle is kind of Inida’s version of the Air Force’s X-37B, except that it is also testing a hypersonic scramjet engine, a cutting edge design that the U.S. has barely been able to fly successfully. Should they succeed, it will place them smack dab in the middle of the elite club of space-faring nations.

Boeing moves to block Russians from selling Sea Launch

9:21 pm

In a reaction to news that the Russians have a potential buyer for Sea Launch, Boeing has sued to block the sale.

In a motion for a preliminary injunction filed with the U.S. District Court for the Central District of California April 2, Boeing argued that a sale of Sea Launch could hinder its ability to collect on a summary judgment issued last year against Energia of at least $300 million. “If Energia succeeds in selling these assets and moving all of the proceeds thereof to Russia, without paying the hundreds of millions of dollars that it owes, it would unquestionably complicate Boeing’s collection efforts,” the company’s lawyers stated in the court filing.

Energia has refused to pay that $300 million. However, since Sea Launch’s floating launch platform remains docked in California, Boeing retains a great deal of leverage in this legal dispute. I expect the court will eventually put a lock on those assets until the Russians pay up.

Russia denies that Proton upper stage failed after launching ExoMars

9:16 pm

At a press conference today the head of Roscosmos today countered claims that some failure had occurred after ExoMars was placed on its course to Mars.

Briefing reporters in Moscow, Igor A. Komarov reiterated statements made by Proton prime contractor Khrunichev Space Center of Moscow, saying the Breeze-M upper stage separated ExoMars without incident and then proceeded with the standard passivation and collision-avoidance maneuvers.

Komarov said he had seen photos taken from a Brazilian ground telescope that appeared to show small objects in the vicinity of the Breeze-M stage and ExoMars. “I do have these pictures, provided by the Brazilian observatory, showing the ExoMars spacecraft surrounded by some dimly illuminated objects reportedly related to the upper stage,” Komarov said.

“Telemetry and other objectively verifiable data available to us, covering the entire time from the separation and the contamination and collision avoidance maneuvers to the passivation of the upper stage, show that all these steps have been performed successfully, without any anomalies,” Komarov said. “There is absolutely no indication of an upper-stage explosion or breakup.”

The uncertainty will only be settled in the next few weeks, when engineers activate all of ExoMars instruments. Should they all be working as expected, then it will likely be that nothing had happened to the Briz-M upper stage, as Roscosmos claims. If not, then Russia has a problem, since it depends on that stage for future Proton commercial launches and will not know what went wrong here.

Close encounter with a dust devil

10:14 am

dust devil near Opportunity

Cool image time! On March 31st, as the Mars rover Opportunity took an image of the tracks it left behind as it attempted to climb the steepest slope it has yet attempted, it unexpectedly captured a nearby dust devil. The image to the right is a cropped version of that image

Be sure and take a look at the original image. Not only is the dust devil clearly imaged, showing it to be intense enough that it casts a shadow, the image gives a very good sense of the steepness of that slope. It is not surprising that Opportunity had problems getting up that hill, and eventually had to retreat because it couldn’t get to its target rock formation.

Using ICBMs to lower launch costs

10:02 am

The competition heats up: Orbital ATK is lobbying Congress to lift a ban on the use of decommissioned ICBM missiles for commercial launches.

Orbital ATK is pressing U.S. lawmakers to end a 20-year ban on using decommissioned intercontinental ballistic missiles (ICBM) for launching commercial satellites and the effort has raised concern among companies that have invested millions of dollars in potential rival rockets. Orbital Vice President Barron Beneski said in an interview on Friday that the company was pushing Washington to get the ban lifted as part of the National Defense Authorization Act that sets defense policy for fiscal 2017, which begins Oct. 1. The missiles were idled by nuclear disarmament treaties between the United States and Russia in the 1990s.

The company wants to use the solid rocket motors in the surplus missiles to increase the capability of their Minotaur 4 rocket, designed for the small satellite market. Interestingly, Virgin Galactic, who is aiming for this same smallsat market with its LaunchOne rocket, is protesting, and has even garnered the lobbying support of the industry’s trade organization..

“It’s a dangerous precedent when the government tries to inject itself in the commercial marketplace. It can be disruptive, and not for the right reasons,” Eric Stallmer, president of the Commercial Spaceflight Federation, a Washington DC-based trade organization, said in an interview on Thursday.

Orbital ATK is not asking for exclusive use, so other companies could also obtain surplus missiles for their own use. However, the ATK in Orbital ATK’s name comes from the half of the company that before the merger was an expert in using solid rockets for space. This gives Orbital an advantage here that the other companies do not have, and explains their protests.

Nonetheless, I say tough. The government should surplus these rockets, and let the competitive chips fall where they may. Anything that lowers the cost to put payloads in orbit cannot be a bad thing for the launch industry, as it will serve to increase the number of customers that industry will have and thus help to increase everyone’s sales figures.

Misuse revealed of vomit comet at NASA

7:16 pm

It appears that, stuck with the “vomit comet” airplane that they no longer had much use for, NASA managers tried to justify its existence and budget by assigning it tasks for which it and its crew were not designed or trained to do.

The unorthodox use of the C-9 aircraft was driven, according to the complaints, by a desire at the high levels of the agency to prove the Vomit Comet was of practical use. Apparently, it didn’t work—the C-9 aircraft program was defunded and shut down in 2014.

Since 1959, NASA has used a variety of aircraft to simulate the weightlessness of space in order to train astronauts and perform basic experiments in zero gravity. From 2005 to 2014, the C-9, built in 1970, became one of NASA’s primary Vomet Comets. According to documents uncovered by Motherboard using the Freedom of Information Act (embedded at the bottom of this article) show that the Vomit Comet was used on at least two occasions for purposes other than simulating space flight, while still labeling the missions “crew training.” In 2013, the agency officially looked into having the plane reclassified to run these types of missions.

In one of these cases, the plane was flown to Greenland without the proper equipment or training for the crew, and experienced what was described by crew as “a near fatal crash.” It didn’t crash, but the crew apparently feared for their lives.

The program was shut down in 2014 with the operations handed over to private companies. Now if NASA needs to train astronauts, they simply hire these companies, which make the bulk of their money flying private missions, something NASA wasn’t allowed to do.

Russia schedules first Vostochny launch

7:08 pm

The competition heats up: Roscosmos has scheduled April 27 as the date for the first launch from its new spaceport in Vostochny.

I do wish them luck. I don’t think the Russians will be very successful at competing in the new private launch industry that is beginning to emerge, centered as they are on Soviet-style, top-down, giant government-run organizations, but I still hope they succeed at whatever they attempt in space. As far as I am concerned, the more the merrier.

Russia insures first Vostochny launch

8:40 am

In the heat of competition: Russia’s space agency Roscosmos has obtained insurance for the first launch from Vostochny, covering the rocket and the launch facilities it will use.

This story tells us more about Russia’s present circumstances than the situation at Vostochny. Normally, government space agencies self-insure. Russia, however, is having serious economic problems, and I suspect that the managers there have recognized that if this launch fails and the launchpad is damaged badly, they don’t have the cash to quickly rebuild it. Granted, the insurance itself will probably cost them a lot of money they also don’t have, but considering the significant quality control problems the Russian aerospace industry has had in recent years, combined with the corruption that has surrounded the construction at Vostochny, they are probably wise to cover themselves in the not unlikely chance that something goes wrong.

Video of Saturday’s New Shepard flight

7:36 pm

Blue Origin has released video of its New Shepard test flight on Saturday, once again in a slick edited presentation rather than raw video of the flight itself. I have embedded this video below the fold.

As promised, the propulsion module came down at full speed until only a few seconds before impact, then fired its engines and gently slowed, then hovered, then touched down without harm. The long shot of it coming down is especially breathtaking.

New Shepard flies again, for the third time

1:23 pm

The competition heats up: On Saturday Blue Origin successfully launched and landed its reusable New Shepard suborbital capsule/rocket spacecraft

The vehicle lifted off from the company’s test site shortly after 11 a.m. Eastern time, according to a series of tweets by company founder Jeff Bezos. The vehicle’s propulsion module, the same one that flew earlier test flights in November and January, made a successful powered landing, he said. Its crew capsule, flying without people on board, parachuted to a safe landing. … The vehicle reached a peak altitude of nearly 103.4 kilometers, slightly above the “von Karman line” frequently used as the boundary of space and similar to previous test flights.

This flight also carried some science experiments, demonstrating that Blue Origin’s customers will not be limited merely to space tourists.
