Ariane 6 gets first commercial contract

8:38 am

Capitalism in space? Arianespace yesterday signed its first commercial contract for its new rocket, Ariane 6.

The Sept. 10 contract is Arianespace’s first with a commercial satellite operator for Ariane 6, and brings to eight the number of Ariane 6 missions on the company’s manifest, assuming none of the Eutelsat satellites are dual-manifested on the same rocket.

Eutelsat executives have suggested for years that the company was willing to be first in line to embrace Ariane 6, including most recently in June 2017 when the company signed a three-launch agreement for Ariane 5 missions.

Eutelsat spokesperson Marie-Sophie Ecuer told SpaceNews by email that the multi-launch agreement came with “attractive terms” that are “fully aligned with our objective to significantly reduce launch cost,” but declined to say if the company received a discount. To woo customers, SpaceX offered discounts of around $10 million to launch on the first Falcon 9 rockets to use previously flown first-stage boosters.

I question the private nature of this deal, in that Eutelsat is a European company with many legal ties to the European Union. Since all reports I’ve seen suggest that Ariane 6 is not going to be as cheap as SpaceX’s rockets, I wonder if some political pressure has been applied to Eutelsat to sign this contract.

Overall, it increasingly appears to me that Ariane 6 will not get much business outside of Europe because of its cost. Much like Russia, Europe is giving up on its commercial international market share, mainly because it can’t or won’t compete with the newer American companies.

SpaceX successfully launches communications satellite

9:12 am

Capitalism in space: SpaceX last night successfully launched a communications satellite as well as recovered the Falcon 9 first stage.

The biggest news here is how routine the landings of the first stage have become, getting its first mention eight paragraphs into the article above, with its landing described almost as an aside. This was a new Block 5 first stage, and it will likely fly again within a relatively short period of time.

The leaders in the 2018 launch race:

24 China
16 SpaceX
8 Russia
6 ULA
5 Arianespace (Europe)

China still leads the U.S. in the national rankings, 24 to 23.

More details about Chinese suborbital launch earlier this week

9:56 am

Link here. The article really only provides one new detail about the flight itself, that the rocket used solid rocket motors. This fact, plus the overall secrecy, suggest to me that the company, iSpace, is doing its work for the Chinese military.

The article at the link also provides a good overview of the entire Chinese “private” smallsat rocket industry.

China is still run from the top, so any “private” rocket company must have the approval and support of the government. What makes China different from Russia, also ruled from the top, is the Chinese government’s willingness to encourage competitive independent operations, something the Russians has not done. The result is that China’s rocket industry is not stagnating, but growing.

A glider sets new altitude record

9:22 am

The Perlan-2 glider yesterday set a new altitude record, reaching an altitude of more than fourteen miles.

Then on September 2, Perlan pilots Jim Payne and Tim Gardner strapped themselves in and rode the glider to an altitude of 76,000 ft (23,000 m), setting a new flight record. This is higher than Lockheed Martin’s jet-powered U2 spy plane flown by the CIA, which reached 73,700 ft (22,475 m), and places it amongst a handful of manned aircraft to sustain flight at such as altitude.

Implied but unstated in the article at the link is the military value of this technology, once combined with drone technology.

SpaceX’s Big Falcon Rocket and the colonization of Mars

7:49 pm

Link here. Lots of details about what SpaceX wants to do, as well as the company’s request for help in areas it is weak.

Below the fold is the youtube video from the Mars Society conference last week which forms the basis of the article at the link.

I only have one comment at this time: I worry that SpaceX is developing a rocket, the BFR, that has no marketable value, at this time. They succeeded with the Falcon 9 and the Falcon Heavy because they could market them and make money from them. The commercial space industry needed these rockets that could fly at lower cost, and that has paved the way for SpaceX’s success.

There are real questions whether a similar market exists for BFR. To paraphrase a line from the movie Field of Dreams, it is possible that if they build it the customers will come, but few businesses succeed with that market strategy.

Hollywood once again reveals its distaste for America

10:36 am

The just released new Hollywood movie detailing the life of Neil Armstrong, First Man, has so far gotten rave reviews.

Sadly, however, there is one detail about the Apollo 11 mission that the filmmakers decided they couldn’t include, even though it was in many ways the entire point of the mission. They made a conscious decision to exclude any mention of the planting of the American flag on the surface of the Moon.

Star Ryan Gosling, who plays Armstrong, defended director Damien Chazelle’s decision to omit the star-spangled moment when asked about it in Venice. “I think this was widely regarded in the end as a human achievement [and] that’s how we chose to view it, ” Gosling said per the Telegraph. “I also think Neil was extremely humble, as were many of these astronauts, and time and time again he deferred the focus from himself to the 400,000 people who made the mission possible.”

The Canadian actor added that based on his own interviews with Armstrong’s family and friends, he doesn’t believe the pioneering astronaut considered himself an American hero. “I don’t think that Neil viewed himself as an American hero,” Gosling said. From my interviews with his family and people that knew him, it was quite the opposite. And we wanted the film to reflect Neil.” [emphasis mine]

This is bunk. All the astronauts who flew to the Moon were very aware that they were warriors in the Cold War against the Soviet Union and communism, and did it very consciously so that the U.S. could win that space race, for the U.S. Planting the flag was thus for them a very important aspect of the mission, maybe in many ways the most important.

That these Hollywood filmmakers purposely excluded that moment only illustrates to me once again the hostility, even hate, that the modern elitist culture has for the United States and everything it has stood for since 1776: freedom, blind justice before the law, and individual responsibility. Here it appears they are making an effort to separate that very decidedly American culture, which made the lunar landing possible, from that achievement. They want to honor Armstrong as an individual, but do not want to give any credit to the country and culture that sent him to the Moon. Instead, they want to claim that the Apollo landings were merely “a human achievement.”

For shame.

This makes me very unwilling to spend any money to see this movie. Why should I support the work of such intellectually dishonest people?

I must add that I have already been emailed by several readers who are similarly outraged. I wonder therefore if this will turn into something that will actually hurt ticket sales. I suspect not, as too many Americans today do not care very much about these issues. They will go to be entertained, and many will buy into the lie that the Apollo missions was an achievement not of America but of the entire global world, working together in love and peace.

Scotland’s first commercial rocket test flight

9:34 am

Capitalism in space: A private smallsat rocket company, Skyrora, has successfully completed a suborbital test flight, the first commercial rocket test flight in Scotland.

Skyrora saw its 2.5 metre (9ft) projectile reach altitudes of almost four miles after taking off at the Kildermorie Estate in Ross-shire. Known as Skylark Nano, it accelerated to Mach 1.45 – more than 110mph.

One could also describe Skylark Nano as nothing more than a big model rocket. Nonetheless, the company is using this test flight to improve its chances to win the competition for some of the money the UK government will award to private companies in connection with the establishment of its new spaceport in Sutherland, Scotland.

Luxembourg announces creation of space agency

9:26 am

The new colonial movement: Luxembourg today announced that it will officially launch its own space agency as of September 12, 2018.

Unlike US space agency Nasa, Luxembourg’s agency will not carry out research or launches. Its purpose is to accelerate collaborations between economic project leaders of the space sector, investors and other partners.

The agency will back an investment fund to invest in promising projects. Head of space affairs Marc Serres told Delano in May 2018 that financing was one of the department’s five pillars. Serres said at the time the fund would be a public private initiative with the state as anchor investor and private investors running it.

As eccentric as Luxembourg’s overall philosophy to tax dollars might be (treating it all as investment capital to invest for profit), this approach in terms of its space agency is right on the money. Not only will their investments bring profits back to their taxpayers (who are really being treated here as investors), they are using this tax money investment as a way to draw private enterprise to their country.

First private patents filed for manufacturing materials on ISS

10:36 am

Capitalism in space: Two private companies, Proctor & Gamble and Made in Space, have filed the first private patents for the manufacture of either materials or supplies on the International Space Station.

These patents are very important, as they specifically describe doing manufacturing in space of objects that can be used in space. There have been many previous patents for research in space, but all have usually related to research for use on Earth.

Virgin Orbit performs more flight tests of 747

9:37 am

Capitalism in space: Virgin Orbit has completed a series of flight tests of the 747 airplane that will be used to launch its LauncherOne smallsat rocket.

The flights of the company’s Boeing 747 aircraft, nicknamed “Cosmic Girl,” were the first since the company installed a pylon on the plane’s left wing that will be used to carry the LauncherOne rocket on future flights of the air-launch system.

The company disclosed few details about the test flights, but flight tracking services such as Flightradar24 list three flights of the aircraft in recent days, most recently Aug. 27, taking off from the Southern California Logistics Airport in Victorville, California. The flights ranged in duration from one and a half to three and a half hours in airspace over the Mojave Desert and over the Pacific Ocean off the California coast.

The company appears to be making progress, though its also appears that their promised first rocket flights are not happening this summer, as previously announced.

Launch schedule shuffles for SpaceX

9:29 am

Link here. A combination of payload issues, scheduling conflicts, and rocket refurbishment demands has forced SpaceX to shuffle and delay many of its remaining launches scheduled for the rest of 2018.

The biggest conflict appears to be between the first manned Dragon test flight, and the second Falcon Heavy flight, both of which are now listed for a November launch. Since both will use the same launchpad, there must be some space between them.

Dragon/Starliner schedules firming up

9:11 am

At a meeting at NASA this week a status update of SpaceX’s manned Dragon and Boeing’s manned Starliner capsules indicated that their proposed flight schedules, with the first manned flights occurring next year, are increasingly firm.

Overall, the updates were quite positive with most of the flight hardware nearing completion. The two companies must each execute two test flights to the International Space Station (ISS) in order to be certified to perform operational crew rotation missions.

On the SpaceX side, the company will first execute an uncrewed test flight of the Crew Dragon spacecraft called Demonstration Mission 1 (DM-1) – currently scheduled for this coming November. It will then be followed by a crewed test flight designated Demonstration Mission 2 (DM-2). In between the two missions, SpaceX will also execute an in-flight abort test.

In terms of Boeing, they will perform an uncrewed Orbital Flight Test (OFT) with the CST-100 Starliner followed by a Crewed Flight Test (CFT). A pad abort test will be also conducted between the two missions.

While Boeing’s schedule for these flights is somewhat uncertain as they investigate the recent failure of several valves to close during an engine test, SpaceX’s schedule has become very solid. Assuming nothing goes wrong on the unmanned test flight in November and the in-flight abort test, they will fly humans in April, 2019.

The shift to smallsats by the U.S. military

10:05 pm

Link here. The story focuses on the first planned constellation of smallsats, hopefully set for launch by 2021.

[DARPA] has mounted a program called Blackjack, which aims to loft a network of 20 prototype spy satellites to low Earth orbit (LEO) in 2021. These craft will be incredibly cheap compared to the current crop: The goal is get each satellite built and launched for about $6 million, said Thomas, the Blackjack program manager.

Blackjack aims to meet this ambitious cost target by leveraging developments in the private space sector. Several companies plan to establish huge constellations in LEO in the next few years, to deliver cost-effective internet service to people around the globe. SpaceX’s Starlink network, for example, will feature thousands of individual satellites.

Blackjack will integrate reconnaissance and communications payloads into standard commercial satellite bodies (known as buses) and take advantage of the high launch rate required to loft the mega-constellations, Thomas said. “The Blackjack approach assumes that we’re not going to be an anchor tenant. We’re not going to be driving these companies,” he said during the FISO presentation. “But we want to take advantage of that production line of spacecraft, the buses especially, that they’re going to be building. We want to take advantage of that launch and take advantage of all of those pieces.”

There’s a lot more at the link. If this first constellation works out, they will upgrade it to a constellation of 90 satellites. And it will based on buying the bulk of its product from the private sector instead of having the military build it. This will provide a wealth of business for smallsat manufacturers as well as smallsat rocket companies.

EXOS completes successful test flight of reusable suborbital rocket

9:30 am

Capitalism in space: EXOS Aerospace yesterday completed a successful test flight of its reusable suborbital rocket, SARGE, at Spaceport America in New Mexico.

The company’s first Suborbital Autonomous Rocket with GuidancE, or SARGE, rocket lifted off from Spaceport America in New Mexico at approximately 2:15 p.m. Eastern. After reaching an unspecified peak altitude, the rocket descended under parachute, landing about 15 minutes later a short distance from the pad. The rocket’s nose cone, descending under a ballute, landed several minutes earlier.

The company didn’t immediately disclose technical details about the flight, such as the peak altitude, but in a live webcast of the launch appeared to be satisfied with the vehicle’s performance, despite the vehicle appearing to veer from its vertical trajectory briefly after liftoff.

“This was a very successful test for us,” said John Quinn, chief operating officer of Exos, on the webcast. “We’re very excited that we had all of our recovery systems operational.”

It sounds as if they were mostly testing the recovery systems that will allow the rocket and payload to land safely in a condition to fly again.

NASA considering purchase of communications services

9:33 am

Capitalism in space: Rather than build its own communications satellites, as it has done in the past, NASA is now considering purchasing these services from private communications satellite companies.

NASA had been studying a next-generation communications system that would ultimately replace the current generation of Tracking and Data Relay Satellite (TDRS) spacecraft in Earth orbit, as well as support missions beyond Earth orbit. That included the possibility of partnerships with the private sector.

“Past networks have been expensive to operate and maintain because they were designed to only serve government customers, which has limited their ability to leverage commercial partnerships,” the agency said in its fiscal year 2019 budget proposal released in February. “The next generation project will engage with commercial industry through mechanisms such as services contracts, hosted payloads, and other public-private-partnerships to allow multiple commercial entities to partner with the Government in order to significantly reduce and eventually eliminate reliance on NASA or NASA contractor run ground systems.”

In a paper presented last year by several NASA officials at the International Astronautical Congress in Adelaide, Australia, the agency said working with both commercial and international partners would be among the elements of its next-generation architecture. “Using open, commercial, and international standards will enable the use of commercial services by specifying required performance and interfaces without specifying provider-specific capabilities,” the paper stated. “Commercial entities will compete based on price, quality, timeliness, support and other factors that maintain a competitive environment.”

That desire to work with the commercial sector, along with harnessing new technologies like optical communications, was a reason cited by NASA a year ago for not exercising an option for an additional TDRS satellite under a contract NASA awarded to Boeing in 2007. The last satellite built under that contract, TDRS-M, launched in August 2017.

Using commercial communications satellites makes perfect sense. It will be faster, provide more redundancy, and will save the taxpayer a lot of money.

Arianespace’s Vega launches European satellite to study the Earth’s winds

9:18 am

Arianespace’s Vega rocket has successfully launched a European satellite dubbed Aeolus designed to study the Earth’s winds.

Funded by the European Space Agency and built by Airbus Defense and Space, the 480 million euro ($550 million) Aeolus mission is nearly two decades in the making. Since receiving ESA’s formal go-ahead in 2002, Aeolus has suffered numerous delays as engineers encountered problems with the mission’s laser instrument.

Aeolus will gather the first comprehensive worldwide measurements of wind speed — over oceans and land masses — from Earth’s surface to an altitude of nearly 100,000 feet (30 kilometers).

Data collected by the Aeolus satellite will be fed into numerical weather prediction models, replacing simulated “boundary conditions” in the computers models with near real-time measurements from space.

The updated leader board for the 2018 launch standings:

22 China
15 SpaceX
8 Russia
6 ULA
5 Arianespace

In the national race, the U.S. and China remained tied at 22.

EXOS to test fly reusable suborbital rocket in New Mexico

8:54 am

Capitalism in space: EXOS Aerospace has chosen Spaceport America in New Mexico as the location where it will test fly its reusable suborbital rocket dubbed SARGE.

EXOS has completed the design, test and build; has received its FAA launch license and completed the final integration and test hovering for the rocket. A successful test flight is needed to solidify the company’s plans to use the technology as the basis for a planned reusable Orbital class vehicle, the company said in a pres release issued Tuesday.

“We are excited to enter into the testing phase of our SARGE platform at Spaceport America, and even more excited to reveal our plans for our Jaguar Reusable (first stage) LEO launcher,” EXOS COO John Quinn said in a prepared statement. “We look forward to enabling space research, manufacturing and educational opportunity for the world by providing frequent suborbital flights that provide fast and affordable access to space.”

Spaceport American CEO Dan Hicks said a successful test flight could lead to further testing and development at the spaceport.

EXOS is another one of the host of new smallsat rocket companies vying for expected large launch needs in the 2020s. For Spaceport America, a state-run spaceport that was built for Virgin Galactic and its hyped surge in space tourism that never happened and thus has seen practically no activity for the past decade, this announcement is helpful in its effort to attract other launch business.

Flying Boeing’s Starliner capsule

9:54 am

Link here. The article provides some nice details about the way the spacecraft will operate (mostly by computer), with the astronauts monitoring and capable of taking over at any point.

Unlike Dragon, the control panel has no touchscreens. According to astronaut Chris Ferguson, the design was “borrowed a little bit from Orion, and it’s kind of the way some of the 5th generation military planes interact with pilots.” Not as fancy, but maybe more practical. I still have my doubts about the ability of astronauts to accurately press a touchscreen during the vibrations of launch.

There is something else, however, about this article that bugs me. It reads too much like an SLS update, filled with glowing reports that, in the case of SLS, are designed to disguise a program that is not going to meet its schedule. This is pure speculation based on nothing but instinct, but it is an impression I have and do not like.

Stratolaunch to build its own upper stages

9:40 am

Capitalism in space: Stratolaunch today announced that it is designing and building three differently-sized upper stage rockets to attach to the fuselage of its giant Roc airplane.

Beside the Pegasus rocket, owned by Northrop Grumman, aimed for first flight in 2020, Stratolaunch will build a medium and medium-heavy rockets, with the former set for a 2022 flight, as well as a fully reusable space plane, now in early development.

The space plane concept would apparently be capable of taking payloads up and down from orbit, and could therefore become the first totally reusable launch capability.

Overall, it does appear that the company, unable to find someone else to design its upper stage, has been forced to do it itself.

NASA officially approves SpaceX’s fueling system

9:08 pm

Surprise, surprise! NASA on August 17 officially approved SpaceX’s fueling system where the astronauts would enter the Dragon capsule before the Falcon 9 rocket would fueled.

In a statement published late Aug. 17, the agency said that it was allowing SpaceX to move ahead with plans to use what’s colloquially known as “load-and-go,” where the Falcon 9 launch vehicle is filled with liquid oxygen and kerosene propellants after astronauts board the Crew Dragon spacecraft on top of the rocket.

“To make this decision, our teams conducted an extensive review of the SpaceX ground operations, launch vehicle design, escape systems and operational history,” Kathy Lueders, NASA’s commercial crew program manager, said in the statement. “Safety for our personnel was the driver for this analysis, and the team’s assessment was that this plan presents the least risk.”

Blah, blah, blah. They had made it clear they were going to approve SpaceX’s fueling approach last week. NASA safety bureaucrats have been whining about SpaceX’s fueling approach for more than a year and a half, for no logical reason, and for what I surmised were purely political reasons having zero to do with safety. At times I have stated that when SpaceX was getting close to actually flying, NASA would back down. And I also expected SpaceX to push its launch dates to force NASA to back down, in contrast to the old-time big space contractors who routinely would kowtow to NASA in these matters and allow its bureaucracy to push them around.

These events are more evidence that the April 2019 manned Dragon launch is on schedule.

SpaceX unveils access arm jetway astronauts will use to board Dragon

2:04 pm

Capitalism in space: SpaceX has begun installing its airport-jetway-like access arm that astronauts will use to board Dragon at Launchpad 39A in anticipation of the first manned flight in April 2019.

They were originally going to install the jetway after the first unmanned demo flight, which they hoped to fly this month. That plan has now changed.

Prior to the visual milestone this week of the Crew Access Arm, or CAA, being moved to the pad surface and the base of the Fixed Service Structure (launch tower), previous information from SpaceX and NASA indicated that the arm would be installed after the Dragon’s uncrewed demo flight.

However, that schedule was based around a launch of the uncrewed Dragon flight, DM-1, in August 2018.

With NASA announcing a 3-month slip to the DM-1 flight (largely due to ISS scheduling and crew reduction aboard the International Space Station in the coming months), SpaceX found itself with an unanticipated delay to the DM-1 flight – which in turn opened up a possibility that didn’t exist before to install the CAA in August.

…But now that DM-1 is NET (No Earlier Than) November – a date Gwynne Shotwell is confident the company will meet, SpaceX is forging ahead with CAA installation because, quite simply, there is no reason to wait, at this point, to install the arm after DM-1.

Making the crew access arm resemble an airport jetway is a fine example of the pizazz that helps sell SpaceX. It also helps make space operations appear more like an ordinary transportation option, something that is necessary if the human race is ever going to become truly spacefaring.

3D-printed solar panels for cubesats!

11:24 am

A solar panel for a cubesat

The image on the right was sent to me last night by engineer Joe Latrell. It shows a 3D-printed solar panel designed for use on a cubesat. As he wrote,

[This is] the first integration of a solar panel with the 3D printed material. The panel is not attached but rather embedded in the plastic during the printing process. This helps protect the panel from transport damage and makes it easier to assemble the final satellite. This design needs a slight adjustment but is almost there.

What makes Joe’s work most interesting is where he is doing it. Last week, in posting a link to a story about a Rocket Lab deal that would make secondary payloads possible on its smallsat rocket Electron, I noted that things were moving to a point where someone could build a satellite for launch in his garage.

This in turn elicited this comment from Joe:

As a matter of fact, I am building a PocketQube satellite for launch in Q3 2019. Yes, I am working in a small shop – just behind the garage. Nothing fancy but the price was right. I am working with Alba Orbital and the flight is scheduled on the Electron. These are very exciting times.

Alba Orbital is smallsat company aimed at building lots of mass produced smallsats weighing only about two pounds.

Anyway, Joe then followed up with another comment with more information:

This first [satellite] is just to see if it can be done. I plan to have it take a couple images and relay data regarding the orientation methods I am planning to use (gravity and magnetic fields). If it works, I am hoping to get funding to develop a small series of satellites to track global water use.

It is also a good way to test some of the materials I think would make spacecraft lighter and cheaper.

Yesterday he sent me the above image. This is the future of unmanned satellites and planetary probes, small, light, cheap, and built with 3D printers by single entrepreneurs. And because of their inexpensive nature, the possibilities for profit and growth are truly almost infinite, which in turn will provide developments that make space travel for humans increasingly smaller, lighter, cheaper, and easier to build as well.

To repeat Joe’s comment, these are very exciting times.

Will SpaceX bail out Tesla?

10:13 am

Link here. There appears to an effort on Wall Street to convince SpaceX to use its significant profits to bail out failing Tesla. It is also unclear whether Musk agrees with this approach.

If SpaceX does this, it will be a very bad thing for the company’s future, throwing good money after bad. Musk might love both companies and what they are trying to accomplish, but the future of the two companies appears to be heading in opposite directions. To weigh SpaceX down with an unprofitable company that has a failing product would seriously harm SpaceX’s abilities in the future.

SpaceX unveils interior of manned Dragon

10:02 am

Capitalism in space: Earlier this week SpaceX unveiled the interior of its Dragon capsule, along with the suits and other details, to reporters in California.

The article at the link has some good videos showing the capsule interior as well as its touchscreen control panel. It also includes quotes from SpaceX’s president Gwynne Shotwell repeating their intention to launch the manned mission by April 2019.

“Whenever we talk about dates we’re always confident and then something crops up,” Shotwell said. “Predicting launch dates can make a liar out of the best of us. I hope I am not proven to be a liar on this one. We are targeting November for Demo 1 and April for Demo 2.”

“I would love to say that this mission is going to be like every other mission, because I want every rocket and every capsule to be reliable, but I can tell you there will be about 7000 extra sets of eyes on the build of this system, the testing of this system and all the interfaces,” Shotwell added.

I would not be surprised if there was a few months slip in that schedule. I will be surprised if it slips more than that.

More testing of “Roc,” Stratolaunch’s giant airplane

10:21 am

This past weekend Stratolaunch completed more tests on its giant airplane, now nicknamed “Roc.”

They had intended to do another taxi test, but didn’t for some reason. Instead, they did test fueling operations. full-power engine tests, and communication tests.

Their upcoming schedule appears to me to be very extended.

Stratolaunch executives laid out the test schedule for the plane, which was built by Mojave-based Scaled Composites, during a space conference in April. The company plans to follow up on the first two taxi tests (at runway speeds of 15 mph and 40 knots) with three more at speeds of 70, 85 and 120 knots.

The last speed is roughly what’s needed for takeoff.

After the fifth taxi test, Stratolaunch would put the plane into the air for a series of flight tests over the course of what’s expected to be 18 to 24 months. In April, executives said they were targeting the first flight test for this summer (which technically runs until Sept. 23).

They also have not yet announced any launch contracts, though there have been announcements that both Northrop Grumman’s Pegasus and Virgin Orbit’s LauncherOne will fly on Roc.

ULA’s Delta-4 Heavy successfully launches the Parker Solar Probe

12:43 am

ULA’s Delta-4 Heavy has successfully launched the Parker Solar Probe.

As I write this the spacecraft is in orbit, but there are several more steps needed to confirm the spacecraft is on course, including a second burn of the upper stage, its separation from the spacecraft, followed by the firing of the solid rocket kick stage and then its separation from the spacecraft. All these steps will take another 40 minutes or so, so reporting them will have to wait until tomorrow.

Update: The spacecraft has successfully separated from its last stage and is on its way.

Over the next two months, Parker Solar Probe will fly towards Venus, performing its first Venus gravity assist in early October – a maneuver a bit like a handbrake turn – that whips the spacecraft around the planet, using Venus’s gravity to trim the spacecraft’s orbit tighter around the Sun. This first flyby will place Parker Solar Probe in position in early November to fly as close as 15 million miles from the Sun – within the blazing solar atmosphere, known as the corona – closer than anything made by humanity has ever gone before.

The leaders in the 2018 launch standings:

22 China
15 SpaceX
8 Russia
6 ULA
4 Japan
4 Europe

The U.S. and China are once again tied in the national rankings, 22 each.

A spinning heat shield to lower their cost and weight

5:44 pm

Link here. Key quote:

Made of a flexible, strong and heat-resistant material that folds down when not in use, his shield automatically starts spinning like a samara-type tree seed when exposed to the onrush of air that a spacecraft would experience when dropping through a planet’s atmosphere.

As it spins, centrifugal force causes its skirt-like sides to flare out and stiffen. This creates the drag needed to help slow the descent, while also providing a large protective surface for the dissipation of heat. No additional machinery, other than the shield itself, is required for its deployment.

“Since this prototype is lightweight and flexible enough for use on smaller satellites, research could be made easier and cheaper,” says Wu. “The heat shield would also help save cost in recovery missions, as its high induced drag reduces the amount of fuel burned upon re-entry.”

More details here. Very clever. It needs to be tested to see if it can work.

Researchers say cubesats with propulsion systems must have encrypted software

9:01 am

Capitalism in space: Researchers from Yale University are recommending that the smallsat industry establish rules requiring all future cubesats that carry their own propulsion systems be encrypted to prevent them from being hacked.

That research by a team of graduate students, presented at the AIAA/Utah State University Conference on Small Satellites here Aug. 9, recommended the space industry take steps to prevent the launch of such satellites to avoid an incident that could lead to a “regulatory overreaction” by government agencies. “We would propose as a policy that, for those cubesats and smallsats that have propulsion, that the industry adopt a ‘no encryption, no fly’ rule,” said Andrew Kurzrok of Yale University.

That recommendation comes as cubesat developers, who once had few, if any, options for onboard propulsion, are now looking to make use of more advanced chemical and electric propulsion systems. Some of those technologies can provide smallsats with large changes in velocity, which can enable major orbital changes.

Kurzrok and colleagues at Stanford University and the University of Colorado modeled several different propulsion systems on a notional 10-kilogram nanosatellite, assuming the spacecraft was in a 300-kilometer orbit and that the propulsion systems accounted for half the spacecraft’s mass. The results ranged from the satellite reaching medium Earth orbit altitudes within two hours when using chemical propulsion to passing geostationary orbit in about a year with an electric propulsion system.

The scenario involving the nanosatellite with chemical propulsion is particularly troubling, he said. “What are the abilities within two hours to track that something isn’t where it’s supposed to be and then warn or take some sort of secondary action?” he said, concluding that the satellite reaching GEO in a year is a much less plausible threat.

The concern, then is a scenario where hackers are able to take control of a satellite and redirect it quickly.

Getting encryption for their software would raise costs, but it really is the cost of doing business. Better for the industry to create these rules than wait for the federal government to step in, as the government regulation will certainly end up being more odious and difficult to change.

Russian lawmaker threatens to block sale of Russian rocket engines to ULA

8:52 am

In response to new U.S. sanctions, a Russian lawmaker has now threatened to block the sale of the Russian RD-180 rocket engine that ULA uses in its Atlas 5 rocket.

Russian lawmaker Sergei Ryabukhin, who heads the budget committee in the upper house of the Russian parliament, responded to the new sanctions by vowing: “The United States needs to finally understand that it’s useless to fight with Russia, including with the help of sanctions.”

According to the Russian news agency RIA, Ryabukhin found a place to hit Washington where it’s soft: the rocket engine. Losing access to the RD-180 would make American access to space—something Donald Trump desires enough to create a separate military service branch devoted to it—much more complicated. The engine helps get everything from satellites to astronauts into orbit.

More details here.

If Russia does this they will be shooting themselves in the foot. ULA is their only customer for the RD-180 engine. Without those sales, they would cut themselves off from one of the few remaining international space contracts they still have, further bankrupting their dying space industry. Furthermore, the U.S. has many other options even if the Atlas 5 can no longer fly. ULA might suffer until it can get a replacement engine, but in the meantime the Falcon Heavy is now available to replace it, at less cost.
