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.

Russian medics have approved UAE’s astronaut candidates

9:19 am

The new colonial movement: Russian medics have now narrowed the candidates for the United Arab Emirates’ (UAE) first spaceflight.

Nine candidates were sent to Russia for testing. The article does not say how many candidates were given medical clearance. Further training in September will narrow the choices further, followed by a final decision by the UAE naming the one person who will fly to ISS.

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.

China reveals landing site for Chang’e-5 lunar sample return mission

8:56 am

The new colonial movement: In a recent paper Chinese scientists revealed their landing plans for the Chang’e-5 lunar sample return mission, presently scheduled for at 2019 launch.

If all goes according to plan, the robotic Chang’e 5 will land in the Rümker region, which lies within a huge basaltic lunar plain called Oceanus Procellarum (Latin for “Ocean of Storms”).

A recent paper lays out the scientific significance of this site, and what Chang’e 5 may be able to find there. “Recent studies find that the geological features and volcanic history of the moon are far more complex than previously thought, and many of the most interesting areas have been neither explored nor sampled,” states the study, which was led by Yuqi Qian of the School of Earth Sciences at the China University of Geosciences in Wuhan. “One such area is the northern Oceanus Procellarum region, which consists of very young (<2 Ga) [less than 2 billion years old] mare materials and hosts one of the largest volcanic complexes on the moon (Mons Rümker)."
For the study, the research team conducted a detailed geological mapping of the Rümker region using imagery, spectral and altimetry data.

Chang’e-5 should not be confused with Chang’e-4, which is set to launch in the fall to land on the Moon’s far side.

The choice of the volcanic region around the Ocean of Storms is significant, as it indicates that, for at least this mission, China is not focused on the possibly more valuable polar regions where water-ice might be present for future lunar bases. Instead, they are giving a priority to science and geology with this probe. They likely also picked this site because it is near the equator and therefore a bit easier to reach on this first daring sample return mission.

It does appear however that China is taking the long view. The landing choice here suggests to me that they plan many more missions to the Moon, and do not see anyone else in a position to compete with them for territory. The U.S., Russia, and Europe appear to be throwing their eggs into the basket of (F)LOP-G, which will merely orbit the Moon and eat up resources preventing these countries from planning and building any landing missions, for decades. India meanwhile might be a competitor, but at the moment it is far behind.

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.

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.

Roscosmos in the news!

9:48 am

Three news stories from Russia, two from today and one from last week, provide us a flavor of the kind of space stories that come out of Russia almost daily, either making big promises of future great achievements, or making blustery excuses for the failure of those big promises to come true.

In the first the head of Roscosmos, Dmitry Rogozin, rationalizes the failure of Russia to compete successfully with SpaceX.

China unveils next lunar rover

8:54 am

The new colonial movement: In unveiling its next lunar rover, China today also announced they will hold a contest to name it.

Images displayed at Wednesday’s press conference showed the rover was a rectangular box with two foldable solar panels and six wheels. It is 1.5 meters long, 1 meter wide and 1.1 meters high.

Wu Weiren, the chief designer of China’s lunar probe program, said the Chang’e-4 rover largely kept the shape and conditions of its predecessor, Yutu (Jade Rabbit), China’s first lunar rover for the Chang’e-3 lunar probe in 2013. However, it also has adaptable parts and an adjustable payload configuration to deal with the complex terrain on the far side of the moon, the demand of relay communication, and the actual needs of the scientific objectives, according to space scientists.

Like Yutu, the rover will be equipped with four scientific payloads, including a panoramic camera, infrared imaging spectrometer and radar measurement devices, to obtain images of moon’s surface and detect lunar soil and structure.

The Chang’e-4 lunar probe will land on the Aitken Basin of the lunar south pole region on the far side of the moon, which is a hot spot for scientific and space exploration. Direct communication with the far side of the moon, however, is not possible, which is one of the many challenges for the Chang’e-4 lunar probe mission. China launched a relay satellite, named Queqiao, in May, to set up a communication link between the Earth and Chang’e-4 lunar probe.

I am not sure what they mean by “adaptable parts and an adjustable payload configuration.” That sounds like they upgraded this rover’s design to allow them to use it to build many similar rovers for use elsewhere, not just on the Moon. This sounds good, but the conditions on other planets are so different I’m not sure a direct transfer of the rover will work very well.

Chang’e-4’s launch is presently scheduled for December.

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.

An update on China’s private smallsat rocket companies

10:09 am

Link here. The article describes the most recent news from OneSpace (which recently secured $44 million in financing), Landspace (building larger rockets), and Exspace (next launch planned for September).

While these companies are structured like American private companies, in China nothing having anything to do with space is really private. None of these companies can do anything without the full approval of China’s authoritarian communist government. Unlike Russia, however, China, has decided to allow competition to drive its space industry, not central control. It is encouraging small independent operations to come up with their own ideas and to compete with each other.

In the end, they will all be co-opted by the government, but for now this policy is producing for China some real results.

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.

India’s prime minister: manned mission by 2022

9:43 am

The new colonial movement: Facing an election next year, India’s prime minister Narendra Modi produced his own Kennedy-like space speech today, announcing a plan to launch a manned Indian mission by 2022.

Wearing a flowing saffron turban, the Hindu nationalist leader also announced the plan to take the “Indian tricolor to space” in a manned mission that would make India the fourth nation to launch one, after the United States, Russia and China. “India is proud of our scientists, who are excelling in their research and are at the forefront of innovation,” Modi said from the ramparts of the Mughal-era Red Fort in Delhi to a crowd numbering in the tens of thousands.

“In the year 2022 or, if possible, before, India will unfurl the tricolor in space.”

He also announced a healthcare initiative that has been dubbed “Modicare.” He was elected in a landslide to replace the socialist policies of the leftwing Congress Party. He is now beginning to act like the U.S.’s establishment Republican Party, who love to mouth conservative values but advocate leftist programs to win re-election.

The question is whether the Indian people will be more like Americans of the 20th century, buying into these government programs proposed by a fake-conservative, or whether they will be more like an increasing number of Americans today, sick of too much government. I suspect the former, which will bode ill for India’s future.

Ghana considers its first national space law

9:20 am

The new colonial movement: Ghana moves to write and pass its first national space law.

In setting out space legislation, Ghana would be following international precedent. More than 25 countries have enacted such laws. The space powers Russia and the US are among them, but so are smaller states like Argentina, Kazakhstan, Indonesia and Iran. Closer to home, Egypt, Nigeria and South Africa already have space laws. Other nations on the continent will undoubtedly follow suit.

A national space law would ensure that space activities launched within Ghana’s jurisdiction – whether on land, ships or aircraft – and perhaps even abroad by its nationals or registered companies are appropriately regulated. Such laws may govern a host of space-related ventures. These include launches; remote sensing and space data protection; aeronautics; rocket and satellite development, space tourism and space mining.

Of course, the complexity of space activities combined with the rapid pace at which technology develops means that national space laws are unlikely to cover every eventuality. They do, however, provide a degree of certainty for the public, investors and courts should disputes arise. National laws also facilitate compliance with global obligations. Article 6 of the Outer Space Treaty, for example, requires all space activities to be authorised and continually supervised by the state. National laws which demand licensing of space activities foster adherence to the treaty.

Article 7 makes states liable for damage caused by space objects under its jurisdiction, including those belonging to private commercial entities. A Space Act can be vital in limiting a state’s liability through provisions on indemnities.

Ghana has signed the Outer Space Treaty. The next step will be for the government to ratify it, and then to establish a legislative framework for space activities. [emphasis mine]

I have highlighted the fundamental problem with the Outer Space Treaty. If Ghana wants to attract investment capital for its space industry, they are forced to sign the treaty. It establishes the only existing rules for liability. Unfortunately, the treaty is also hostile to freedom, and puts the government in charge, which is why it has taken so long for private enterprise to finally gain a foothold in space.

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.

ISRO head: Recall of India satellite prevented a failure

5:55 pm

K. Sivan, the chairman of ISRO, India’s space agency, revealed today that the decision to recall GSAT-11 in April just as it arrived in French Guiana for a May Ariane 5 launch prevented a major failure.

They had decided to recall it because two previous satellites had failed, using almost identical equipment. As he notes,

GSAT-11 had the same set of power system configuration that two older satellites had. RISAT-1 died prematurely and GSAT-6A lost communication contact soon after launch on March 29 because of suspected power system failure, harnesses etc… We had just sent GSAT-11 [to Guiana] and no one was sure if the same issue was there in GSAT-11,” he said.

Checks found that the provision or “margin” for the deployment of the solar panel was much smaller than was required. “Had it gone in that configuration, the panel [which generates power for the 15-year life] would not have deployed in space. The satellite would have been a failure.”

Because the recall cost money and delayed the launch significantly, it required the ability to look at the engineering honestly and not let politics interfere. Sivan and his managers did that, which speaks well for future space engineering from ISRO.

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.

The two things SpaceX must do for NASA to okay the first manned Dragon mission

10:08 am

Link here.

First, they must successfully recover the Dragon capsule from the first unmanned test flight in November so that they can use it in a launch abort test to follow.

Second, they must demonstrate seven successful flights of the Block 5 version of the Falcon 9 rocket.

Right now it appears that, though the schedule is very very tight, it is possible that SpaceX will be able to accomplish these tasks in time to do its manned flight in April 2019, as presently scheduled. At the moment SpaceX’s launch schedule calls for 11 Falcon 9 launches between now and April. Getting seven Block 5 launches should therefore be likely, though not certain, since some of those launches will probably not use the final full Block 5 configuration.

I notice that the article makes no mention of the massive paperwork that the GAO says must be done before a manned flight. No surprise. In the end the paperwork will not delay this mission, despite what the GAO and NASA’s bureaucracy says.

UPDATE: NASA has now withdrawn its objections to SpaceX’s fueling plans. This is also no surprise, as their objections to fueling the rocket while astronauts were on board were always bogus. The risks are essentially the same whether you fuel before boarding or after. Either way, there is a lot of very explosive fuel present. To say NASA’s way, fueling first, is the only way never made sense.

UK estimates its new spaceport could capture thousands of smallsat launches

9:51 am

Capitalism in space: Estimates by the United Kingdom’s space agency suggest that its new spaceport in Scotland could capture thousands of smallsat launches by the end of the 2020s.

Figures released … suggest that existing ‘rideshare’ small satellite launches (small satellites piggybacking on larger missions) are capable of meeting less than 35% of the total demand. This reveals a significant gap in commercial small satellite launch provision for which future UK spaceports are well placed to compete.

The press release also gives an update on the recent actions of the two smallsat rocket companies, Orbex and Lockheed Martin (in partnership with Rocket Lab), to establish operations in Scotland.

It remains to be seen whether these predictions will come true. Right now it appears that a giant boom in the smallsat industry is about to happen, and if it does the need for launchpads will become critical. If so, the policy shift in the UK to favor private spaceflight is arriving at just the right time.
