Mitsubishi offers its H3 rocket to Artemis

11:04 am

Earlier this week Japan announced that it planned to become a partner in NASA’s Artemis program to build a space station in lunar orbit.

That announcement was very vague. Yesterday an official from Mitsubishi Heavy Industries might have offered the first real detail, suggesting that its new H3 rocket, scheduled for its first lift-off in 2020, could be used to launch components for Artemis, as early as 2025. The official described one option for using the H3, sending Japan’s upgraded ISS cargo freighter, the HTV-X, to Gateway in 2025 or 2026.

Launching an HTV-X cargo vessel to the gateway would require two H3 launches, he said. The first launch would send an HTV-X into an orbit around the Earth, he said. The second launch would send up an upper stage with an enlarged fuel tank to dock with the HTV-X and propel it to the Gateway, he said.

What was not stated was who will pay for this. The U.S.? Japan? Either way Mitsubishi, which has failed badly in garnering any of the international commercial satellite business for its H2B rocket, is clearly trying to attract business now for the H3 rocket, supposedly designed to be cheaper to launch.

Firefly to use Aerojet Rocketdyne’s AR-1 engine

10:55 am

Capitalism in space: Firefly has agreed to purchase Aerojet Rocketdyne’s AR-1 engine to use in it larger Beta rocket, presently under development.

Though deal also includes help from Aerojet for the development of Firefly’s smaller Alpha rocket,

…the companies made clear that the centerpiece of the agreement was the potential use of the AR1 on Firefly’s Beta rocket, giving Aerojet a customer for the engine while allowing Firefly to increase the performance of the medium-class rocket.

Beta is intended to fill the niche once served by ULA’s Delta 2. “It has left an opportunity for a modern launcher to come in at perhaps a better price point than Delta 2, and can address some of the new missions coming out,” such as small geostationary orbit satellites, he said.

The target payload capacity of Beta is eight metric tons to low Earth orbit, a size Markusic explained was driven by the market and which, in turn, led to a design change for the rocket. Beta’s original design resembled the Alpha but with two additional first stages as side boosters, a triple-core design like the Delta 4 Heavy or Falcon Heavy. Beta is now a single-core vehicle with an AR1 engine in its first stage.

Aerojet Rocketdyne had gotten a lot of Congressional money to develop the AR-1 with the intent it would be used in ULA’s Vulcan rocket. ULA has instead chosen Blue Origin’s BE-4 engine, leaving Aerojet Rocketdyne high and dry without any customers. This deal might save that company, while making Firefly more competitive and robust. Moreover, because of all that money from Congress, Aerojet has probably been able to offer the engine at cut-rate prices.

A smart deal all around.

Is Justice investigation really getting serious about anti-Trump coup attempt in FBI/CIA?

2:56 pm

Two stories that have been trending like crazy through the conservative news media in the past 24 hours suggest that the investigation by the Justice Department into the anti-Trump spying and coup attempt by the FBI and the CIA might finally be heating up.

I remain somewhat skeptical. The first story is based on two anonymous sources, which makes me very suspicious. I purposely waited before reporting on it because I have found such stories too often turn out to be either fake or unreliable.

I also don’t take the second story very seriously because Horowitz has been promising his FISA report now for months. His promises, and non-delivery, have increasingly reminded me of Richard Branson’s endless promises that “SpaceShipTwo will be flying in space in mere months!”

At the same time, it is important to note both stories. Horowitz’s FISA probe will be released. And Durham’s investigation, under Attorney General William Barr’s direction, has appeared to be so far aggressive and pointed. If both deliver what these stories suggest, then we might finally get some real prosecutions of some real villains, people in the FBI and CIA who conspired for the past three years to try to overturn a legal U.S. election.

NASA to send new rover to lunar south pole

2:36 pm

NASA today announced that it is building a lunar rover that it will send to the lunar south pole, with a target launch date of December 2022.

About the size of a golf cart, the Volatiles Investigating Polar Exploration Rover, or VIPER, will roam several miles, using its four science instruments — including a 1-meter drill — to sample various soil environments. Planned for delivery to the lunar surface in December 2022, VIPER will collect about 100 days of data that will be used to inform the first global water resource maps of the Moon.

This rover appears to be a traditional NASA project, designed, built, and managed by various NASA agencies that also subcontract the work out to private contractors. As the press release says,

VIPER is a collaboration within and beyond the agency. VIPER is part of the Lunar Discovery and Exploration Program managed by the Science Mission Directorate at NASA Headquarters. Ames is managing the rover project, leading the mission’s science, systems engineering, real-time rover surface operations and software development. The hardware for the rover is being designed by the Johnson Space Center, while the instruments are provided by Ames, Kennedy, and commercial partner, Honeybee Robotics. The spacecraft lander and launch vehicle that will deliver VIPER to the surface of the Moon, will be provided through NASA’s Commercial Lunar Payload Services (CLPS) contract, delivering science and technology payloads to and near the Moon. [emphasis mine]

The highlighted words however indicate where this project differs from the past. The launch vehicle and lander are not being designed and built by NASA. They will be provided by commercial vendors.

Too many smallsat rockets to count

9:23 am

Capitalism in space: According to a report by a Northrop Grumman engineer who has been trying to list these things, the number of companies trying to develop small rockets for the burgeoning smallsat market has grown so large that it is now difficult to track.

Of the 148 small launch vehicles on a popular industry watch list, about 40 efforts “are likely dead but the watch list continues to grow,” Carlos Niederstrasser, a Northrop Grumman master systems engineer, said at the 2019 International Astronautical Congress here.

The problem for Niederstrasser and anyone trying to keep up with the market is that the list continues to grow. “Every time I kill off one [launch vehicle], two more show up,” he said.

…U.S. companies are responsible for 21 of the vehicles Niederstrasser considers active development programs. Seven are from China, four from Spain and three from the United Kingdom. Germany, India and Japan each have two small rocket development programs. Many other countries have a single effort underway.

We should see the shake-out in this new market take place during the next five years. By then at least four rockets should be operational, and the smallsat technology more mature and capable of many things now done by larger satellites.

Virgin Galactic stocks go public on October 28

9:13 am

Buyer beware: With the official completion of a merger of Virgin Galactic with the venture capital company Social Capital Hedosophia this week, it will be possible to buy stock in the company as early as Monday, October 28.

The space-tourism company run by billionaire Sir Richard Branson has been approved to merge with Social Capital Hedosophia, a venture capital firm that helps technology companies list on public markets, according to a Wednesday SEC filing from the company.

The merger is expected to close Friday. On Monday, Social Capital’s ticker, “IPOA,” will become Virgin Galactic’s, and trade under “SPCE.”

As I say, buyer beware. Virgin Galactic has spent fifteen years spending a lot of investment capital without achieving what it promised to do years ago, fly tourists on suborbital space flights. Along the way we’ve seen Richard Branson make a lot of exciting announcements about how he is about to fly in space, none of which ever happened. Instead, they crashed their spaceship, killing one pilot.

If you want to invest money in this company you should be aware of their so far poor track record.

Congressman questions Northrop Grumman-Air Force ICBM deal

9:07 am

The head of the House Armed Services committee yesterday questioned the appropriateness of the Air Force awarding Northrop Grumman an ICBM contract without any competition.

[House Armed Services Committee Chairman Adam Smith (D-Washington.)] said he is troubled that only one company, Northrop Grumman, will be bidding for the Ground Based Strategic Deterrent, a program to replace the Minuteman 3 ICBMs that make up the ground-based portion of the nation’s nuclear forces.

Northrop Grumman and Boeing were expected to compete head to head to be GBSD prime contractors but Boeing decided in July it would not submit a proposal because of Northrop’s overwhelming advantage as the nation’s largest manufacturer of solid rocket motors.

Northrop Grumman’s advantage here comes from its purchase of Orbital ATK last year, which provided the company this solid rocket launch capability that apparently no one else has.

Smith’s complaints here also extend to the Air Force’s plans to pick only two companies in the next year to launch all of its satellites for the next half decade, rather than leave the bidding open to all. As Smith noted,

“I have worked with them [the Air Force] on launch and other things and it strikes me that they are way too close to the contractors that they’re working with,” he said. “They seem to show bias,” Smith added. “It could be incompetence. But I think it is more likely that they like their historical partners. This is really, really bad because competition is a good thing.”

Smith appears generally correct. The Air Force made a sweet non-competitive launch deal with ULA back in the early 2000s that cost the taxpayer billions. Now it seems it is doing the same with its ICBM replacement contractor, and also wants to do the same with its satellite launch contracts. I hope Smith is successful in changing the Air Force approach.

Virgin Orbit to add 3rd stage to LauncherOne for planetary missions

8:56 am

Capitalism in space: Even as it prepares for its first orbital demonstration flight, Virgin Orbit today announced that it is considering development of a third stage that will make the rocket capable of launching planetary cubesat missions.

John Fuller, Virgin Orbit advanced concepts director, said the company is deciding between three “highly energetic third stage” options for LauncherOne that would enable the rocket to launch up to 50 kilograms to Mars or 70 kilograms to Venus. The “Exploration 3-Stage Variant” of LauncherOne would also have the ability to launch around 100 kilograms to the moon or toward Lagrange points, he said.

“What we do is we take that third stage and bring the overall impulse of the vehicle up to a point where we can reach very high energies to launch to cis-lunar, interplanetary or even asteroid targets,” Fuller said Oct. 24 at the 70th International Astronautical Congress here.

The company however has still not flown the rocket, and that first flight is now about a year-plus behind schedule. They say they are preparing for the first orbital mission before the end of year but until it happens there is plenty of room for skepticism.

December 17 officially set for Starliner unmanned orbital launch

8:49 am

Capitalsm in space: NASA and Boeing have now officially scheduled the launch of Boeing’s Starliner capsule on its first unmanned demo flight to ISS for December 17.

Boeing had announced this date earlier, but it is now official.

The next two months will be a very busy period for tests of the two privately built manned capsules being built by Boeing and SpaceX. Not only will Boeing fly Starliner on its first unmanned orbital mission, the company will also do a pad abort test of Starliner on November 4. SpaceX in turn will be doing a major parachute test campaign for Dragon, as well as a launch abort test, right now roughly scheduled for late November.

If all go well, both companies will be ready for the first manned flights of both capsules in the first quarter of 2020.

Ancient glacier flows on Mars

Ancient glacial flow in Euripus Mons
Click for full image.

Cool image time! In the recent download of images from the high resolution camera of Mars Reconnaissance Orbiter (MRO), I found the image on the right, rotated, cropped, and reduced to post here. It shows an example of the many glacial flows coming off of the slopes of Euripus Mons, the sixteenth highest mountain on Mars.

We know these are glaciers because data from SHARAD, the ground-penetrating radar instrument MRO, has found significant clean ice below the surface, protected by a debris layer that insulates it. As planetary scientist Alfred McEwen of the Lunar & Planetary Laboratory in Arizona explained to me in a phone interview yesterday,

These are remnant glaciers. Basically they form like glaciers form. They are not active or if they are they are moving so extremely slowly that effectively they are not active.

If you look close, you can see that this particular glacier was made up of multiple flows, with the heads or moraines of each piled up where each flow ended. In addition, this overall glacier appears to have been a major conduit off the mountain, following a gap between more resistant ridges to the east and west.

The sequence of moraines suggest that when the glacier was active, it experienced alternating periods of growth and retreat, with the growth periods being shorter and shorter with time. As a result each new moraine was pushed less distance down the mountain as the previous one.

Euripus Mons is interesting in that it has a very large and distinct apron of material surrounding it, as shown in the overview image below.
