Sierra Nevada introduces its cargo version of Dream Chaser

6:35 pm

The competition heats up: Sierra Nevada has unveiled a revised cargo version of Dream Chaser, competing for NASA next round of freighter contracts to ISS.

They have made a number of changes, but the most significant is the new folding wings, allowing the spacecraft to fit inside the fairings of most rocket systems. This also eliminates one of the concerns I have read about the previous design on whether its wings could have withstood exposure to the maximum atmospheric stresses experienced during launch.

Lockheed Martin enters the competition to supply cargo for ISS

5:42 pm

The competition heats up: Lockheed Martin has joined Sierra Nevada, Orbital ATK, Boeing, and SpaceX in bidding for NASA’s next contract to ferry cargo to ISS.

Lockheed’s proposal is different in that it proposes a two spacecraft operation. The cargo would be hauled up in a very simple storage bin, where a long-term orbital tug would grab it and take it to ISS. The idea is that they would only have to build and launch the complicated thrusters, robot arms, computers, and avionics of their cargo freighter once, thereby saving money.

Two companies will be chosen. Since the first competition back in the mid-2000s, when NASA picked SpaceX and Kistler for the first cargo round, the quality of the bids has improved remarkably. Back then, NASA had to choose from a bunch of new companies, none of which had ever done this before. The big companies (Boeing, Lockheed Martin) then poo-pooed the competition, saying that it couldn’t be done as cheap as the new companies claimed. After Kistler went under and was replaced by Orbital, they and SpaceX proved the big companies were wrong.

Now the competition includes all the big players, except that those big players are no longer offering expensive systems but cut-rate efficient designs that are as cost effective as SpaceX and Orbital’s first designs.

Virgin Galactic says LauncherOne will make its first flight in 2016

9:35 pm

The competition heats up: The CEO of Virgin Galactic, George Whitesides, revealed at a satellite conference that they are on schedule for LauncherOne to make its first flight before the end of 2016.

The company recently started hot-fire tests of an engine called Newton 3 developed by Virgin Galactic for the first stage of LauncherOne, Whitesides said. That engine, capable of generating 265,000 to 335,000 newtons of thrust, uses liquid oxygen and kerosene propellants. “We’re now to the point where we’re very confident that we can build a very affordable rocket,” Whitesides said. After his speech, he said the company was on schedule to begin flights by the end of 2016, with even initial test flights likely carrying some satellites.

That it is Whitesides and not Richard Branson saying this makes me more confident that it is true, though I remain very skeptical of any promise made by anyone these days at Virgin Galactic. However, the impression from this article confirms an earlier impression I have had, that the company is beginning to shift its resources away from suborbital tourism with SpaceShipTwo and towards orbital launch services with LauncherOne. Branson had announced LauncherOne as a concept in 2012, but only recently have we begin to hear of any actual work on it.

A Mars One finalist accuses the company of fraud

9:24 pm

One of the finalists in the one-way-to-Mars competition by the company Mars One has now accused the company of fraud.

Most egregiously, many media outlets continue to report that Mars One received applications from 200,000 people who would be happy to die on another planet — when the number it actually received was 2,761.

As [finalist Joseph] Roche observed the process from an insider’s perspective, his concerns increased. Chief among them: that some leading contenders for the mission had bought their way into that position, and are being encouraged to “donate” any appearance fees back to Mars One — which seemed to him very strange for an outfit that needs billions of dollars to complete its objective. “When you join the ‘Mars One Community,’ which happens automatically if you applied as a candidate, they start giving you points,” Roche explained to me in an email. “You get points for getting through each round of the selection process (but just an arbitrary number of points, not anything to do with ranking), and then the only way to get more points is to buy merchandise from Mars One or to donate money to them.”

There’s more at the link. Essentially, the whole operation has apparently devolved into a petty scam to milk money from the finalists themselves.

None of this surprises me. From the beginning I considered the whole proposal unrealistic, which thus almost forced the people in charge to commit fraud.

Russia abandons super-rocket designed to compete with SLS

9:39 am

The competition heats up: Russia has decided to abandon an expensive attempt to build an SLS-like super-rocket and will instead focus on incremental development of its smaller but less costly Angara rocket.

Facing significant budgetary pressures, the Russian space agency, Roscosmos, has indefinitely postponed its ambitious effort to develop a super-heavy rocket to rival NASA’s next-generation Space Launch System, SLS. Instead, Russia will focus on radical upgrades of its brand-new but smaller Angara-5 rocket which had its inaugural flight in Dec. 2014, the agency’s Scientific and Technical Council, NTS, decided on Thursday, Mar. 12.

For Russia’s space industry, it appears that these budgetary pressures have been a blessing in disguise. Rather than waste billions on an inefficient rocket for which there is no commercial demand — as NASA is doing with SLS (under orders from a wasteful Congress) — they will instead work on further upgrades of Angara, much like SpaceX has done with its Falcon family of rockets. This will cost far less, is very efficient, and provides them a better chance to compete for commercial launches that can help pay for it all. And best of all, it offers them the least costly path to future interplanetary missions, which means they might actually be able to make those missions happen. To quote the article again:

By switching upper stages of the existing Angara from kerosene to the more potent hydrogen fuel, engineers might be able to boost the rocket’s payload from current 25 tons to 35 tons for missions to the low Earth orbit. According to Roscosmos, Angara-A5V could be used for piloted missions to the vicinity of the Moon and to its surface.

In a sense, the race is now on between Angara-A5V and Falcon Heavy. It shall be quite exciting to watch this competition unfold between big government and private enterprise over the next few decades.

Virgin Galactic test flights to resume in 2015?

9:25 am

I’ll believe it when I see it: The executive director of the New Mexico Spaceport Authority, which runs Spaceport America, said Tuesday that she hopes Virgin Galactic will resume test flights of a SpaceShipTwo suborbital ship sometime in 2015, with commercial flights beginning in 2016.

She claimed that work on the new ship is about 80% completed, with construction of another ship also underway.

Forgive me if I have my doubts. Virgin Galactic has spent more than a decade making these promises, with no results.

A new song for space

9:14 am

At a press conference Sarah Brightman yesterday revealed that she is working with Andrew Lloyd Webber to create a new song to sing when she visits the International Space Station later this year.

She also said that she will sing it from the station near the end of her visit. While the reason she gave for this schedule was because she needed time to adjust to weightlessness, I also see this as good marketing, allowing time for a pr build-up to get the largest audience possible.

Aerojet Rocketdyne to cut costs and streamline operations

9:08 am

The competition heats up: In renaming itself from GenCorp to Aerojet Rocketdyne, the company also announced today a four year program to cut costs and reduce its workforce by 10%.

It appears that most of the cuts will come from upper management, which suggests the company has identified fat it needs to get rid of in order to compete effectively in the re-energized aerospace industry.

Japan successfully tests new solar power technology

8:36 am

The competition heats up: In a test of technology necessary to make space-to-Earth solar power generation possible, Japanese engineers were successfully able to precisely control the transmission of microwaves over a distance of 55 meters.

The main obstacle to generating electricity in space for use on Earth has been getting that power down to Earth. Microwaves can do it, but beaming microwaves through the atmosphere is no good as it will cook everything in the beam’s path. Being able to beam that transmission very precisely for long distances, something not yet possible, will reduce this problem.

????? – John Wilson Orchestra

6:01 pm

An evening pause: This pause is going to be a challenge. I am curious who can most quickly identify the film that this suite comes from, performed here live in 2013. I am sure that anyone that knows anything about movies will figure it out by around 2:30, but can you do it sooner? One hint: this is one of the greatest and most popular films ever made.

NASA schedules commercial manned demo missions to ISS

6:45 pm

The competition heats up: NASA has now added to its ISS schedule the planned launch dates for the first demo missions of SpaceX’s and Boeing’s privately built manned capsules.

For Boeing, its CST-100 will first launch on an uncrewed test flight to the Station via the “Boe-OFT” mission in Apr, 2017 – on a 30 days mission, ending with a parachute assisted return. Should all go to place, the second mission will involve a crew – yet to be selected – on a mission designated “Boe-CFT”, launching in July, 2017, on a 14 day mission to the ISS.

The [planning] dates show SpaceX to be the most advanced in the Commercial Crew path, with their projected test flight dates currently set to win the honor of being the first Commercial Crew vehicle to arrive at the orbital outpost. That first Dragon 2 mission, designated “SpX-DM1″, has a December, 2016 launch date, ahead of a 30 day mission – most of which will be docked to the ISS – ending with a parachute assisted landing in the Pacific ocean. This would be followed by “SpX-DM2″, a crewed flight, launching in April of 2017, on a 14 day mission. This would mark the first time astronauts have launched from American soil on a US built spacecraft since Atlantis’ STS-135 mission in 2011.

American manned space exploration should begin to get very exciting in the next two years, with multiple companies now capable of putting humans in space.

India announces scheduled to test a prototype space plane

9:48 am

The competition heats up: India’s space agency ISRO has announced that they will test fly a prototype space plane sometime between April and June this year.

The test and prototype both sound very similar to Europe’s IXV prototype space plane, test flown only a few weeks ago.

“Technology Demonstrator winged body vehicle weighing 1.5T will be lofted to a height of 70 km using solid booster, thus attaining five times the speed of sound. Thereafter, it will descend by gliding and splashing down into the sea”, said an official statement. This test flight would demonstrate the Hypersonic aerodynamics characteristics, Avionics system, Thermal protection system, Control system and Mission management.

Both programs also remind me of many similar NASA engineering test programs, most of which ended up as dead ends, with the new technology never applied to actual real world missions. Whether that happens in Europe and India remains the main question. The increasing competition in space should help prevent it, but these are also government-run programs, so their goal has less to do with profit and competition than pork and political maneuvering.

NASA considering ion engines for next Mars orbiter

9:40 am

Rather than using conventional chemical thrusters for a Mars orbiter planned for the 2020s, NASA managers are considering using ion engines instead.

Worried its fleet of Mars orbiter is aging, NASA intends to dispatch the spacecraft to the red planet in September 2022 to link ground controllers with rovers and extend mapping capabilities expected to be lost when the Mars Reconnaissance Orbiter stops functioning.

Engineers also want to add ion engines to the orbiter and fly the efficient electrically-powered thruster system to Mars for the first time, testing out a solar-electric propulsion package that officials say will be needed when astronauts visit the red planet. Ion engines produce just a whisper of thrust, using electric power to ionize atoms of a neutral gas and spit out the particles at high speed. While the drive given by the thrusters is barely noticeable in one instant, they can operate for months or years, burning scant fuel compared to traditional chemical rockets.

That this decision requires long-winded and extended high level negotiations at NASA illustrates the slow and lumbering nature of government. Private enterprise is embracing ion engines now, and NASA itself is seeing its own spectacular ion engine success with Dawn. The decision should be a no-brainer, especially because the benefits of ion engines (low weight, more power, greater flexibility) are so obvious.

Britain narrows its competition for spaceport

9:17 am

The competition heats up: The British government has down-selected its choices for a future spaceport in Great Britain to six airports, two of which have already said they are not interested in taking on the job.

The remaining four sites include two in Scotland, and one each in Wales and southwestern England. If I had to choose just based on orbital mechanics, the English site would win, as it is farther south thereby capable of putting more payload in orbit for the same fuel. However, politics and pork will certainly be a factor in any final decision, as this spaceport location is being decided not by private companies but by the British government.

SpaceX has another successful commercial launch

9:26 am

The competition heats up: SpaceX’s Falcon 9 rocket successfully launched its first two-satellite payload to geosynchronouse orbit on Sunday.

The satellites were unusual in that they both have replaced all their chemical engines with ion engines, thus saving weight and cost.

While the satellites will need six to seven times longer to reach the desired orbit, the cost savings is enormous. “The advantage of that, of course, is you don’t carry liquid chemical fuel, which is very heavy,” Betaharon said. “This particular satellite, each of them weigh around 2,000 kilograms. Typically, if you get a satellite like that from other manufacturers, or even from Boeing using chemical propulsion, they would weigh something around 3,500 to 4,000 kilograms, or in some cases maybe more. That’s why, because it’s lower mass, we managed to put two of them on one rocket, which right away reduces your launch costs in half.”

When ABS and Eutelsat signed up for Falcon 9 launch services several years ago, the rocket cost about $60 million. “We paid under $30 million for each satellite, which is almost unheard of,” Betaharon said.

More information about the new satellite designs can be found here.

Nonetheless, the combined weight of the two satellites plus the need to get them to geosynchronous orbit forced SpaceX to forgo another attempt to land its first stage vertical. The rocket needed the fuel to get the satellites where they had to go.

Small satellite industry predicted to blossom

2:07 pm

The competition heats up: An industry study now predicts that more than 500 small satellites, including nanosats, cubesats, microsats, and minisats, will be launched in the next five years.

Note however this important detail, highlighted below:

75% of the 510 satellites to be launched during the next five years will be for government civil and defense agencies. Growth in government demand will be stronger than in the commercial world where a total of 130 satellites are expected. “Large constellation projects such as those announced in 2014 by OneWeb and by SpaceX in association with Google have not been included in our forecasts/scenarios for launch by 2019,” said Rachel Villain, Principal Advisor at Euroconsult and Editor of the report. “Large constellation projects could, however, represent a very significant component of launches over the following five year period (2020-2024).” [emphasis mine]

Even though the predicted launches represent a two-thirds increase per year compared to the previous decade, this launch rate does not include the big private constellations that appear almost certain to fly. In other words, all signs point to the possibility that we are about to see a real boom in the space industry.

The Honey Trees – Moon River

6:01 pm

An evening pause:

Moon river, wider than a mile
I’m crossing you in style some day
Oh, dream maker, you heart breaker
Wherever you’re going, I’m going your way

Two drifters, off to see the world
There’s such a lot of world to see
We’re after the same rainbow’s end, waiting, round the bend
My Huckleberry Friend, Moon River, and me

Hat tip Edward Thelen.
