Space transport roundup – June.7.2019

A sampling of recent articles, videos, and images dealing with space transport:

** Rocket Lab prepares for an upcoming launch, the seventh for the Electron rocket.

** China launched a Long March 11 rocket this week from a sea platform for the first time. The rocket, which has 4 solid-fueled stages, is essentially a military missile converted to an orbital launcher. The payload consisted of seven smallsats for government, education, and commercial applications.

** ESA promotes Ariane 6, Vega C, and Space Rider projects this week:

** The Space Rider is a reusable lifting body vehicle similar to the X-37B: Space Rider: Europe’s reusable space transport system – ESA

Initially proposed in 2016, ESA’s Space Rider reentry vehicle provides a return to Earth and landing capability that compliments the existing launch options of the Ariane and Vega families.

Having recently completed system and subsystem preliminary design reviews, Space Rider is advancing quickly towards the Critical design review at the end of 2019.

Launched on Vega-C, Space Rider will serve as an uncrewed high-tech space laboratory operating for periods longer than two months in low orbit. It will then re-enter the Earth’s atmosphere and land, returning its valuable payload to eager engineers and scientists at the landing site. After minimal refurbishment it will be ready for its next mission with new payloads and a new mission.

Space Rider combines reusability, in-orbit operations and transportation, and precise descent of a reentry vehicle able to safely traverse and land close to inhabited zones. These are major developments, set to extend European knowhow across a host of applications allowing industry to open up new markets.

** Russia starts development of reusable boosters: Russian hi-tech firm working on technology of space rocket’s reusable stages – TASS

Russia’s Energomash Research and Production Association is working on the technology of carrier rockets’ reusable first stages, Energomash Chief Designer Pyotr Lyovochkin said in an interview published in the June edition of the Popular Mechanics journal.

“We constantly explain to rocket builders that if we had the operational technology of returning first stages, they would have no need to buy quite an expensive engine from us just for one flight. Today both rocket builders and we have started to develop such technologies,” Lyovochkin said.

** Virgin Orbit loses most of the OneWeb launch contracts and isn’t happy about it: Virgin Orbit takes OneWeb to court over canceled launch contract – SpaceNews.com

Virgin Orbit is suing OneWeb for refusing to pay a termination fee for canceling all but four of the 39 launches it ordered from Virgin Orbit in 2015 to fill gaps in its planned constellation of at least 648 broadband satellites.

*** Falcon 9 with the Radarsat Constellation set to lift off on June 12 from Vandenberg AFB: SpaceX Falcon 9 and $1B satellite trio set for first California launch in months – Teslarati

After the better part of both half a year of launch delays and launch pad inactivity, SpaceX and Falcon 9 are ready to return the company’s California-based SLC-4 facilities to action with the launch of the $1 billion Radarsat Constellation Mission (RCM).

Built by Maxar for the Canadian Space Agency (CSA), RCM is a trio of remote-sensing spacecraft designed with large surface-scanning radars as their primary payload. Having suffered years of technical delays during Maxar’s production process, RCM was initially available for launch as early as November 2018. In an unlucky turn of events, issues on the SpaceX side of things took RCM’s assigned Falcon 9 booster out of commission and lead to an additional seven or so months of launch delays. At long last, RCM is just one week away from heading to orbit, scheduled to launch from Vandenberg Air Force Base (VAFB) no earlier than 7:17 am PDT (14:17 UTC), [June 12th].

*** Falcon Heavy STP-2 launch set for June 22nd from Cape Canaveral includes NASA payloads among the 24 total spacecraft: Media Briefing Highlights NASA Tech on Next SpaceX Falcon Heavy Launch | NASA

NASA is sending four technology missions that will help improve future spacecraft design and performance into space on the next SpaceX Falcon Heavy rocket launch. Experts will discuss these technologies, and how they complement NASA’s Moon to Mars exploration plans, during a media teleconference Monday, June 10 at 1 p.m. EDT.

*** SpaceX still trying to catch nosecone fairings: SpaceX’s Mr. Steven preparing for first Falcon 9 fairing catch attempt in months – Teslarati

SpaceX recovery vessel Mr. Steven has spent the last several weeks undergoing major refits – including a new net and arms – and testing the upgraded hardware in anticipation of the vessel’s first fairing catch attempt in more than four months.

Required after a mysterious anomaly saw Mr. Steven return to Port in February sans two arms and a net, the appearance of a new net and arms guarantees that SpaceX is still pursuing its current method of fairing recovery. Above all else, successfully closing the loop and catching fairings could help SpaceX dramatically ramp its launch cadence and lower costs, especially critical for the affordable launch of the company’s own Starlink satellite constellation.

*** Speeding up booster turnarounds: SpaceX beats Falcon 9 recovery records after company’s heaviest launch ever  Teslarati

Completed on May 30th, SpaceX’s latest Falcon 9 booster recovery smashed several internal speed records, unofficially cataloged over the years by watchful fans.

In short, as the company’s experienced recovery technicians continue to gain experience and grow familiar with Falcon 9 Block 5, the length of booster recoveries have consistently decreased in the 12 months since Block 5’s launch debut. Already, the efficiency of recovery processing has gotten to the point that – once SpaceX optimizes Block 5’s design for refurbishment-free reuse – there should be no logistical reason the company can’t fly the same booster twice in ~24-48 hours.

*** A report on the Boca Chica Beach activities and the local community: Before Elon Musk reaches Mars, SpaceX may need to survive south Texas – Business Insider

Developing this system at the company’s remote and privately controlled Texas facility comes with several advantages. The area is fairly close to the equator, which adds a natural speed boost to rockets. SpaceX’s autonomy over the site also gives the company more flexibility in scheduling launches, privacy from competitors, and greater freedom in how it uses the land.

But launching a skyscraper-size rocket from this area (engineering challenges notwithstanding) is no trivial undertaking. For one, any future flight path must avoid populated islands. The bay-bottom mud and sand below SpaceX’s site also cause dense structures and tall towers tend to sink and lean. Gulf Coast weather is a challenge, too, as SpaceX recently saw when gale-force winds damaged its Starhopper.

And then there are the 20 or so people, like the Pointers, who live in or near Boca Chica Village. For them, the unparalleled view of the experimental rocket program, while stirring, is also foreboding.

** A binary asteroid zipped past earth recently: Binary asteroids, key to Earth’s planetary defence – ESA

Humankind has had its closest look yet at a binary asteroid. As 1999 KW4 skimmed past our planet at 70 000 km/h, the most advanced visible-light telescope on Earth resolved the 1.3-km diameter asteroid and its 360-m sized moon. An even closer spacecraft-based encounter will come next decade, when NASA will send a probe to deflect the moon of the distant Didymos binary. Then ESA’s Hera mission will perform a follow-up survey right down to the body’s surface.

The International Asteroid Warning Network (IAWN) coordinated a cross-organisational observing campaign of the asteroid 1999 KW4 as it flew by Earth, reaching a minimum distance of 5.2 million km on 25 May. Since its orbit is well known, scientists were able to predict this flyby and prepare the observing campaign.

Side by side observation and artist's impression of Asteroid 199
“The unique capabilities of the SPHERE instrument on ESO’s Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on 25 May. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO’s front-line technology could be critical in planetary defence. The left-hand image shows SPHERE observations of Asteroid 1999 KW4. The angular resolution in this image is equivalent to picking out a single building in New York — from Paris. An artist’s impression of the asteroid pair is shown on the right.” – ESA

** Update on Japan’s Hayabusa2’s visit to Ryugu, a near-earth asteroid: Hayabusa2 drops second target marker, targets artificial crater for sample collection | The Planetary Society

Japan’s Hayabusa2 spacecraft has successfully dropped a second target marker on Ryugu. The reflective softball-sized sphere, which contains the names of Planetary Society members and other supporters, will give the spacecraft a visual guide if mission planners send it back to the surface to attempt a second sample collection.

JAXA is now considering collecting the sample directly from the area where Hayabusa2 created an artificial crater in early April, thanks to updated imagery collected during an aborted touchdown marker drop attempt in mid-May.

** Comets provided earth with much of its water: Comet Provides New Clues to Origins of Earth’s Oceans – NASA JPL

The mystery of why Earth has so much water, allowing our “blue marble” to support an astounding array of life, is clearer with new research into comets. Comets are like snowballs of rock, dust, ice, and other frozen chemicals that vaporize as they get closer to the Sun, producing the tails seen in images. A new study reveals that the water in many comets may share a common origin with Earth’s oceans, reinforcing the idea that comets played a key role in bringing water to our planet billions of years ago.

The Stratospheric Observatory for Infrared Astronomy, SOFIA, the world’s largest airborne observatory, observed Comet Wirtanen as it made its closest approach to Earth in December 2018. Data collected from the high-flying observatory found that this comet contains “ocean-like” water. Comparing this with information about other comets, scientists suggest in a new study that many more comets than previously thought could have delivered water to Earth. The findings were published in Astronomy and Astrophysics Letters.

** Jupiter’s magnetic field exhibits unexpected variations over time: Juno space probe identifies changes in Jupiter’s magnetic field – Physics World

An important question for the researchers to answer now is what is the cause of the shift in Jupiter’s magnetic field? On Earth, the change is thought to originate in the planet’s core, however the best explanation for secular variation on Jupiter is in its deep atmospheric (zonal) winds. These winds extend up to 3000 km into the surface of the planet, where the conductive metal fluid is situated. Although the origin of zonal winds is still uncertain, they are believed to interrupt the magnetic field distribution.

The discovery will likely have implications for the study of our Solar System. Kimee Moore, a graduate student  from the University of Cambridge and lead author of the report on the findings, says that in the future “scientists will be able to make a planet-wide map of Jupiter’s secular variation” and this latest finding may even help “scientists studying Earth’s magnetic field, which still contains many mysteries to be solved”

** Latest on the Sun’s spot count: Sunspot update May 2019: The long ramp down | Behind The Black

The Sun in May continued to show the exact same amount of activity as it had shown for March and April. This steady uptick in sunspot activity once again shows that the ramp down to full solar minimum will be long and extended.

That we are definitely ramping downward to minimum, even with the slight increase in the past three months, is shown by the fact that the Sun has shown no sunspots for the past fifteen days. In fact, all the activity shown in May comes from the first half of the month. This pattern is actually a reflection of the Sun’s 27-day rotation period. …

** A film of a solar eclipse in 1900 was found and restored: First movie of solar eclipse rediscovered | Behind The Black

The magic of a real solar eclipse filmed on 28 May, 1900 by a famous magician, Nevil Maskelyne, while on an expedition by The British Astronomical Association to North Carolina. In 1898 he travelled to India to photograph an eclipse. He succeeded but the film can was stolen on his return journey home.

It was not an easy feat to film. Maskelyne had to make a special telescopic adapter for his camera to capture the event. This is the only film by Maskelyne that we know to have survived. The original film fragment held in The Royal Astronomical Society’s archive has been painstakingly scanned and restored in 4K by conservation experts at the BFI National Archive, who have reassembled and retimed the film frame by frame.

The film is part of BFI Player’s recently released Victorian Film collection, viewers are now able to experience this first film of a solar eclipse since the event was originally captured over a century ago.

ESA made two announcements today: ExoMars Trace Gas Orbiter is shifting orbit, and they officially opened a new Rover Operations Control Centre (ROCC) in Turin, Italy. ROCC will support the Rosalind Franklin rover’s deployment from the Kazachok lander and surface operations after that. Along with the announcements they posted some cool images.

*** Signs of even more water on Mars:

From Space.com:

Scientists think they’ve stumbled on a new cache of water ice on Mars — and not just any ice but a layered mix of ice and sand representing the last traces of long-lost polar ice caps.

That’s according to new research based on data gathered by NASA’s Mars Reconnaissance Orbiter, which has been circling the Red Planet since 2006 and has just marked its 60,000th trip around Mars. On board the spacecraft is a radar instrument that can see about 1.5 miles (2.5 kilometers) below the planet’s surface — and in that data, scientists see lots and lots of ice.

… one of a number taken by the rover in the past week, showing water clouds drifting over Gale Crater.

Mars clouds as seen by Curiosity
Mars clouds over Gale crater as seen by Curiosity. Via Behind the Black.

According to NASA JPL:

These are likely water-ice clouds about 19 miles (31 kilometers) above the surface. They are also “noctilucent” clouds, meaning they are so high that they are still illuminated by the Sun, even when it’s night at Mars’ surface. Scientists can watch when light leaves the clouds and use this information to infer their altitude.

But Curiosity wasn’t just looking at the clouds:

While these clouds teach us something about Martian weather, the big rover news this week was that the data obtained from the two drill holes taken in April show that the clay formation that Curiosity is presently traversing is definitely made of clay, and in fact the clay there has the highest concentration yet found by the rover.

**** Crater? Pit? Volcano? – A puzzling feature might be an impact crater but maybe not:

I would not bet much money on this conclusion. The overall terrain of the Eridania quadrangle is filled with craters, large and small. There does not seem to be any obvious evidence of past volcanic activity, and if there had been it has not expressed itself in large volcanoes.

Eridania crater
This circular feature in the Eridania region could be a meteoroid crater or a volcano caldera. Via Behind the Black.

However, other images of this mountain show many circular features that at first glance appear to be craters like the featured image. They appear slightly raised above the surrounding terrain, though not in as pronounced a manner.

They all could be small volcanoes. Or maybe they are impacts that hit a dense surface which prevented them from drilling too deep down, and instead caused the crater to be raised above the surrounding terrain.

‘Tis a puzzle. The irregular pit in this particular feature adds to the mystery. It does not look like the kind of pits one sees in calderas. Instead, its rough edge suggests wind erosion.

**** The mysterious slope streaks of Mars – Streaks on the sides of sloped surfaces are puzzling…

… and appear to possibly represent a phenomenon entirely unique to Mars. I became especially motivated to write about these mysterious ever newly appearing features when, in reviewing the May image release from the high resolution camera on Mars Reconnaissance Orbiter (MRO), I found four different uncaptioned images of slope streaks, all titled “Slope Stream Monitoring.” From this title it was clear that the MRO team was re-imaging each location to see if any change had occurred since an earlier image was taken. A quick look in the MRO archive found identical photographs for all four slope streak locations, taken from 2008 to 2012, and in all four cases, new streaks had appeared while older streaks had faded.

Brief Answers to the Big Questions
– Stephen Hawking

Space tourism roundup – June.4.2019

A sampling of recent articles, videos, and images related to commercial human space travel:

** Beth Moses talks about her SpaceShipTwo flight and what she is doing to prepare others for such flights:

Describe to me the experience of being in space. We all saw that picture of you staring out the window in complete awe.

It was just magic and almost indescribable.

I felt very fortunate to fly where I did and the day I did. I felt like the Earth was so beautiful, but even more so than you can describe or can be imagined. I happened to fly on a day where we had snow on the mountains in the southwestern United States. And I remember vividly that appearance of glistening white mountaintops and blue Pacific Ocean and the green of the Earth. I told someone the other day I felt like Earth was wearing her diamonds for us that day, because it was so, so glistening and sharp.

It just took my breath away. It was amazing

“The face you make when you look back on Earth from space. Our Chief Astronaut Instructor, Beth Moses, is the 571st person to fly to space and the first woman to fly on board a commercial spaceship.” – Virgin Galactic

Clash: Compare the real flight to the simulations.

Moses: The Gz [force through the head] was of a much lower duration. I reached our expected Gz on boost and re-entry, but was pleasantly surprised at how short it was. It just ramps up and then ramps off. You take a breath and realize, ‘Oh this is high G,’ and you take another breath and say, ‘Oh, this is high G.’ By the time you’ve finished your second breath, it’s done, and you’re back to normal G. The Gz felt like the centrifuge, but the Gx [force through the chest] I didn’t perceive as strongly as I did in the centrifuge. I don’t know why. Maybe it was because I was so happy to be going up. So Gz felt like the NASTAR centrifuge, Gx did not. Both maximums were about 3.6.

Clash: Will you fly again?

Moses: I would love to go back up, but I also want to get future astronauts up there as fast as possible. So it depends on what we still have to test, how many test flights we have and for what reasons. We’re actually still mapping that out. But I will not nominate myself. There are lots of other skill-sets and factors that need to be tested, so I will train other folks to do those tests. I’m not trying to blindly hog evaluations. But if there are evaluations that need my particular skill-set, I might fly again. We’re still working that out.

** Richard Branson remains steadfastly upbeat about Virgin Galactic’s prospects: Richard Branson: We’re at the dawn of new era of space exploration (Opinion) – Richard Branson/CNN

I said after the flight on December 13, as I stood with our pilots, Frederick “CJ” Sturckow and Mark “Forger” Stucky, that when you set off on important adventures, exceptional people come forward to join the journey — people who are consistently by your side and on your side, people who share your dreams and people who help make them reality. Reaching space has been the ultimate team effort.

It is evident that we are finally at the dawn of a new age of space exploration, which will see reusable space vehicles built and operated by commercially successful private companies, transforming our business and personal lives in ways that we have yet to comprehend fully.

Standing on the flight line, I could hear my dad in the back of my mind saying, as he often did, “Isn’t life wonderful?”

** Suborbital space tourism will be a lot safer than climbing Mt. Everest, thankfully: Everest deaths: Four reasons why this climbing season went wrong – BBC News

Over the past two decades, the average annual death rate of climbers on Mount Everest has remained at about six.

But this spring, at least 10 people have already been reported dead or missing on the world’s highest peak.

This is also the season that saw a record 381 climbing permits issued by the Nepalese government.

In reality, this means about 600 people were preparing to embark on the climb, with permit holders accompanied by support staff up the mountain.

** Virgin Galactic & Blue Origin near space tourism operations. VG is currently installing the interior seating in a SpaceShipTwo rocketplane and plans to begin flying customers this year. Blue Origin expects to fly people on the New Shepard for the first time in 2019, though ticket sales have yet to begun. So suborbital space tourism may finally get off the ground this year:  Suborbital space tourism nears its make-or-break moment – The Space Review

After the Ansari X Prize was won in October of 2004, I was sure that there would be regular space tourism services available by 2008. (I lost a bet, in fact, that there would be services by then.) Here it is 15 years later and I’m still waiting to see routine flights of public citizens to the edge of space.

This is disappointing for sure but it is hardly unusual that a technology takes a lot longer than expected to reach the market.

I enjoy listening to Jonathan Strickland on the TechStuff Podcast tell captivating stories behind the development and commercialization of technologies. He explains the science and engineering in a clear and straight-forward manner while also drawing fine verbal portraits of the fascinating characters involved and vividly depicting the often bitter and complex battles among them.

Many of the technologies we take for granted today saw decades pass between the initial key invention(s) and commercial success. I just listened, for example, to a podcast about compact audio cassette tapes and another on video cassettes. (These are in a series from Strickland on the development of media starting with records and films.) While not nearly as challenging as high altitude rocket transportation, there was still a considerable gap between the initial invention of flexible audio tape in Germany in the 1930s and high-fidelity audio cassettes in the 1970s.  The first video tape recorders appeared in the 1950s but the first successful home video recorders didn’t appear until the mid-1970s.

Technological devices typically involve multiple sub-technologies that must work well together as a system. Finding the optimum combination of technologies that synergize into an affordable, practical product seldom happens on the first try. Instead an evolutionary competition occurs with the fittest combo eventually winning after a long struggle that leaves behind a trail of failed designs and bankrupted companies.

In the mid-2000s, there was at least a half-dozen companies making serious efforts at a suborbital vehicle for space tourism. There was no grand overarching roadblock that a few keen outsiders saw that the companies didn’t. Rather, each encountered particular individualized hurdles that tripped them up.

For example, Virgin Galactic could have developed a SpaceShip 1.5 vehicle that involved modest improvements to the 3-seat SpaceShipOne and starting flying within a couple of years after the XPRIZE. Burt Rutan has said he had customers requesting flights on the SpaceShipOne. Instead, VG decided to jump straight to an elaborate 8-person vehicle. Unfortunately, the company ran into tremendous difficulties in scaling up the hybrid rocket motor used on the SS1 and even today does not have a motor that can send the SS2 above 100 km, which was the altitude boundary for the XPRIZE.

XCOR made good progress on low-cost, reliable liquid-fueled rocket engines but could not raise sufficient funding to bring the Lynx spaceplane to fruition. Rocketplane Ltd.‘s design based on a converted Learjet turned out not to be viable and by the time they changed the design they were out of money. Similarly, TGV Rockets fell short of funding to build the Michelle-B, a vertical takeoff and landing rocket vehicle similar to Blue’s New Shepard.

Blue Origin had plenty of funding but, after flying a couple of prototype vehicles, the company decided to focus on developing a new liquid hydrogen propulsion system that could be used for the booster of a suborbital vehicle and also for the upper stage of an orbital launcher. A highly reusable LOX/LH2 engine is no trivial technology so there’s little surprise it took them a few years to develop.

The suborbital space tourism story is just another confirmation that a new technology needs multiple entrants, all trying their hardest to make their designs work.

So, if the SpaceShipTwo and New Shepard vehicles do start flying regularly, does that guarantee a successful space tourism business? No, of course, not. No untried business is a guaranteed success. However, there are many positive signs.

For example, several hundred people have signed up for SS2 flights and most have waited patiently for many years. Only a few percent canceled after the 2014 accident and many of these dropped out not because of safety concerns but because they were discouraged by the additional years of waiting to fly.

If 600 people each year attempt to scale Mt. Everest, despite an annual average of 6 deaths, just to brag about the ordeal they overcame, we can be sure there will be no shortage of customers willing to pay for the totally unique thrill of riding a rocket straight up to the edge of space and encountering the awesome view of a glittering cosmos above and a glistening Earth below.

** A UBS Global Research view of commercial space travel:

** Russia’s KosmoKurs (КосмоКурс) is developing a suborbital vertical takeoff and landing rocket vehicle similar to Blue Origin’s New Shepard and also intended for tourism services. Like the New Shepard, up to six passengers would ride in a capsule that detaches from a booster and returns via parachutes. The goal is to build the vehicle by 2023.

According to McPike’s suit, he contacted Space Adventures in July 2012 about the possibility of flying on a mission around the moon that the company had been promoting for several years. In March 2013, he signed an agreement committing to participate in such a mission, and paid an initial deposit of $7 million towards the $150 million total price with the expectation that the mission would take place within six years.
