Negotiations underway to shift 1st stage landings at Kennedy to new site

9:58 am

Capitalism in space: Negotiations between the Air Force, NASA, and Space Florida (which runs the spaceport) have begun to establish a new location at Kennedy for 1st stage rocket landings.

The goal would be to lessen the burden landings impose on the Cape’s nearby industrial area, which workers must evacuate for hours during some missions. “If we have to stop operations for a launch during the middle of day, it is severely impacting to other customers,” Brig Gen. Wayne Monteith, commander of the Air Force’s 45th Space Wing, said Tuesday during a transportation conference at Port Canaveral.

As outlined in KSC’s master plan, the new landing pad could be built near the northern end of the spaceport’s secure perimeter — north of pad 39B and south of State Road 402 leading to Canaveral National Seashore’s Playalinda Beach. “We have land further to the north that’s not populated like the industrial area of the Cape is, and that might make for a really good location for a new landing zone for an increased landing rate,” said Nancy Bray, KSC’s director of spaceport integration and services.

I expect that SpaceX, should it be forced to shift landings from its just built landing sites, will also need to be in these negotiations since it will likely want some reimbursement for that work.

Rocket Lab pins down cause of launch abort

9:48 am

Capitalism in space: Rocket Lab has identified the cause of yesterday’s abort of its Electron rocket, and is ready to proceed tomorrow with the launch.

Rocket Lab says its launch yesterday was aborted due to rising liquid oxygen (LOx) temperatures feeding into one of the Electron’s nine engines. The launch attempt was aborted two seconds before lift-off from its range on Mahia Peninsula between Gisborne and Napier.

It says it will attempt to launch again tomorrow – after 2.30pm – and that the 17m rocket or pad equipment wasn’t damaged.

The company said the slight LOx temperature increase was a result of a ”LOx chill-down bleed schedule” that was not compatible with the warm weather.

This is not that different than the kinds of issues SpaceX experienced in its early launch attempts of both its Falcon 1 and Falcon 9 rockets. It appears that getting the temperature and pressure of the liquid oxygen right is critical, and requires some in use trials to figure it out. With SpaceX, they eventually were able to enhance the process enough to allow them to cool the oxygen to make it more dense and thus get more of it in the tanks to increase the rocket’s launch capacity.

Orbital ATK gets first FCC license approval for space repair mission

9:38 am

Capitalism in space: Orbital ATK has gotten its first FCC license approval for its Mission Extension Vehicle 1 (MEV-1) robotic space repair mission, set to launch late in 2018.

Space Logistics [a subsidiary of Orbital ATK] has a contract with fleet operator Intelsat of Washington and Luxembourg to provide in-orbit servicing with MEV-1 — the first in a proposed fleet of satellite servicers Dulles, Virginia-based Orbital ATK intends to build — with service beginning in early 2019.

In a public notice issued Dec. 8, the FCC authorized Space Logistics to use four different frequency bands for telemetry, tracking, and command (TT&C) of MEV-1 as the servicer completes post-launch maneuvers, reaches the graveyard orbit for decommissioned geostationary satellites some 300 kilometers above the geosynchronous arc, and attaches to Intelsat-901.

Space Logistics’ MEVs works by connecting to a satellite and taking over station-keeping, using fuel onboard the servicer to propel the satellite and extend its life. Most geostationary satellites are forced into retirement after 15 years or more due to a shortage of fuel. “It is in our plan for Intelsat-901 that at the end of the five-year life extension mission that we would return the IS-901 to the graveyard orbit and release them there. After that release the MEV would then proceed onto our next client,” Anderson said, adding that the next client has not yet been identified.

They will still need to obtain additional permits from both the FCC (for future operations) and from NOAA (because the spacecraft’s cameras, needed for docking, might also look at the Earth).

Why NOAA has this permitting power astonishes me, but then, in today’s government-run America, I probably should not be surprised. If we were trying to settle the west today we would likely have a whole range of government agencies requiring wagon train approval, route approval, and scheduling approval.

Ariane 5 successfully launches 4 European GPS satellites

9:27 am

Capitalism in space: Using its Ariane 5 rocket Arianespace yesterday successfully placed four European Galileo GPS satellites in orbit.

This is expected to be Arianespace’s last launch for 2017. The standings for the most launches in 2017 as of today:

27 United States
18 Russia
16 SpaceX
15 China
11 Arianespace

SpaceX and Russia each have two scheduled launches, while China has one. China however does not release information about all of its upcoming launches, so it might surprise us with more.

Saturn’s rings are very young

8:57 am

Data from Cassini’s last ring-diving orbits has now strengthened the hypothesis that Saturn’s rings formed very recently, just a few hundred million years ago.

Saturn acquired its jewels relatively late in life. If any astronomers had gazed at the sky in the time of the dinosaurs, they might have seen a bare and boring Saturn.

It was then that some sort of catastrophe struck the gas giant. Perhaps a stray comet or asteroid struck an icy moon, tossing its remnants into orbit. Or maybe the orbits of Saturn’s moons somehow shifted, and the resulting gravitational tug-of-war pulled a moon apart. However it happened, two new lines of evidence from Cassini make it clear that the rings were not around in the early days of the solar system 4.5 billion years ago, as scientists had long believed, says Jeff Cuzzi, a ring specialist at NASA’s Ames Research Center in Mountain View, California. “It rules out the primordial ring story,” Cuzzi says. “That’s what it looks like to me.”

At the moment there is no consensus on what might have caused the rings formation so recently.

Blue Origin successfully flies upgraded New Shepard capsule

8:48 am

Capitlism in space: Blue Origin yesterday successfully completed the first flight of its upgraded suborbital reusable New Shepard spacecraft.

Further details noted this test was called Mission 7 (M7), featuring a next-generation booster – powered by its BE-3 engine – and the first flight of Crew Capsule 2.0, a spacecraft that now features real windows, measuring 2.4 x 3.6 feet.

The test flight also carried 12 payloads and even a passenger – specifically an instrumented dummy brilliantly named “Mannequin Skywalker”.

Further details noted the flight time was 10 minutes and six seconds, launching at 10:59 a.m. CT from Blue Origin’s West Texas test site. The booster achieved Mach 2.94 on ascent & Mach 3.74 on descent. It again showed its landing skills, as shown on the video released by Mr. Bezos.

I have embedded the company’s video below the fold.

MU69 might have a moon

1:51 pm

Worlds without end: Observations of stellar occultations this past summer of 2014 MU69, New Horizons’ Kuiper belt target for a January 1, 2019 fly-by, suggest that the object is not only very elongated or two objects practically touching as they orbit around each other, but it might have a moon orbiting it.

The data that led to these hints at MU69’s nature were gathered over six weeks in June and July, when the team made three attempts to place telescopes in the narrow shadow of MU69 as it passed in front of a star. The most valuable recon came on July 17, when five telescopes deployed by the New Horizons team in Argentina were in the right place at the right time to catch this fleeting shadow — an event known as an occultation – and capture important data on MU69’s size, shape and orbit. That data raised the possibility that MU69 might be two like-sized objects, or what’s known as a binary.

The prospect that MU69 might have a moon arose from data collected during a different occultation on July 10, by NASA’s airborne Stratospheric Observatory for Infrared Astronomy (SOFIA). Focused on MU69’s expected location while flying over the Pacific Ocean, SOFIA detected what appeared to be a very short drop-out in the star’s light. Buie said further analysis of that data, including syncing it with MU69 orbit calculations provided by the European Space Agency’s Gaia mission, opens the possibility that the “blip” SOFIA detected could be another object around MU69. “A binary with a smaller moon might also help explain the shifts we see in the position of MU69 during these various occultations,” Buie added. “It’s all very suggestive, but another step in our work to get a clear picture of MU69 before New Horizons flies by, just over a year from now.”

All of this is somewhat speculative. We really won’t know until New Horizons arrives next year.

Faults on Mars

9:20 am

Faults on Mars

Cool image time! The Mars Reconnaissance Orbiter (MRO) image on the right, reduced in resolution to post here, captures a distinctive fault line that cuts across some layered deposits. As noted by the MRO science team,

Some of the faults produced a clean break along the layers, displacing and offsetting individual beds (yellow arrow).

Interestingly, the layers continue across the fault and appear stretched out (green arrow). These observations suggest that some of the faulting occurred while the layered deposits were still soft and could undergo deformation, whereas other faults formed later when the layers must have been solidified and produced a clean break.

Meridiani Planum

These layers are located in Meridiani Planum, a relatively flat area on the Martian equator. Opportunity landed on this plain to the southwest of this region, as shown on the geology map to the left. The white cross in the southwest corner indicates Opportunity’s landing site, with Endeavour Crater just to the southeast. The white box in the northwest shows where the faulted layered deposits are located. Based on the scale of the map, this places Opportunity approximately 400 miles away.

What exactly caused these distinct faults remains unknown. The likely cause would be a earthquake, but since Mars does not have plate tectonics like the Earth, earthquakes would have to be caused by other geological processes not yet studied.

To my eye, they look like cracks in a mirror, though this provides no real explanation other than it illustrates how cool the image is.

Flying through Jupiter’s Great Red Spot

8:40 am

Cool movie time! In conjunction with the release yesterday of data from Juno’s first close fly-over of Jupiter’s Great Red Spot, the science team also released an animation of what it would be like to fly down into the Spot.

You can also download the mp4 file here. It is definitely worth watching. It illustrates forcefully how daunting and challenging it will be for the human race to ever explore the vastness of Jupiter. This simulated plunge only goes into the Great Red Spot a few hundred miles, and barely touches its dynamics.

Rocket Lab launch aborted at engine start

10:27 pm

Capitalism in space: The second test flight of Rocket Lab’s Electron rocket was aborted just after engine start today (December 12 in New Zealand).

Members of Rocket Lab’s launch team called out ignition of the first stage’s engines as the countdown ticked off the final few seconds before liftoff, followed by an abort.

“Umbilicals in, power’s all up,” one member of the launch team called out over a loop broadcast on Rocket Lab’s live video stream. “Confirm Stage 1 engines have stopped,” an engineer later announced.

A countdown graphic on Rocket Lab’s video feed stopped at T-minus 2 seconds. “As you can see, the vehicle had an abort during the launch auto sequence,” said Daniel Gillies, Rocket Lab’s mission management and integration director who provided commentary on the company’s webcast. “At this stage of flight, the vehicle flight computer is actively monitoring a wide range of vehicle performance parameters, and when any of these parameters are violated, the vehicle determines that its not ready of flight and holds the count.”

The rocket is fine. Though they have not said what caused the abort, they have set their next launch attempt for two days from now, in the evening in the U.S.

Juno’s look at Jupiter’s Great Red Spot

3:10 pm

The Juno science team released its results from the spacecraft’s first close fly over of Jupiter’s Great Red Spot in July 2017.

Jupiter’s Great Red Spot is a giant oval of crimson-colored clouds in Jupiter’s southern hemisphere that race counterclockwise around the oval’s perimeter with wind speeds greater than any storm on Earth. Measuring 10,000 miles (16,000 kilometers) in width as of April 3, 2017, the Great Red Spot is 1.3 times as wide as Earth.

“Juno found that the Great Red Spot’s roots go 50 to 100 times deeper than Earth’s oceans and are warmer at the base than they are at the top,” said Andy Ingersoll, professor of planetary science at Caltech and a Juno co-investigator. “Winds are associated with differences in temperature, and the warmth of the spot’s base explains the ferocious winds we see at the top of the atmosphere.”

The future of the Great Red Spot is still very much up for debate. While the storm has been monitored since 1830, it has possibly existed for more than 350 years. In the 19th century, the Great Red Spot was well over two Earths wide. But in modern times, the Great Red Spot appears to be diminishing in size, as measured by Earth-based telescopes and spacecraft. At the time NASA’s Voyagers 1 and 2 sped by Jupiter on their way to Saturn and beyond, in 1979, the Great Red Spot was twice Earth’s diameter. Today, measurements by Earth-based telescopes indicate the oval that Juno flew over has diminished in width by one-third and height by one-eighth since Voyager times.

The storm’s estimate depth, about 200 miles, seems gigantic, but then we must remember this storm is on a gas giant that is about 88k miles in diameter, about ten times larger than Earth. The relative size of this storm to the size of Jupiter therefore is really not that much different than the relative size of big hurricanes on Earth. At the same time, the realities here are daunting, filled with unknowns, chief of which is the fact that unlike Earth, the Great Red Spot is a storm that is floating high in the atmosphere with no solid surface below it.

Trump signs new space policy directive, making Moon 1st priority again

2:57 pm

Yawn. President Trump today signed a new space policy directive that makes the Moon the U.S.’s first exploration priority again.

“The directive I am signing today will refocus America’s space program on human exploration and discovery,” said President Trump. “It marks a first step in returning American astronauts to the Moon for the first time since 1972, for long-term exploration and use. This time, we will not only plant our flag and leave our footprints — we will establish a foundation for an eventual mission to Mars, and perhaps someday, to many worlds beyond.”

As I wrote above, yawn. Same old same old. In 2004 Bush declared we will go to the Moon. In 2010 Obama declared we will go to an asteroid. In 2017 Trump declares we will go to the Moon.

In all those years, where have we actually gone? Nowhere. The government’s effort during all that time to build a rocket and a manned spacecraft to do any of this stuff has come up completely empty. Neither will carry humans into space for at least another five years, if not longer.

The only thing these empty promises have accomplished is to waste a god-awful amount of taxpayer money, now about $33 billion, with appropriations likely to increase that to more that $43 billion before that first manned SLS/Orion flight.

I predict that this government promise will come up empty as well, at least in the manner the government and NASA is trying to sell it. It won’t be the government rocket and capsule that will get us back to the Moon, but a host of new private companies, making profits and doing things efficiently and fast, that will get us there. And I am firmly confident that they will do it before the government even gets off the ground.

New method to 3D print entire objects simultaneously, without layering

10:56 am

Life imitates science fiction: Engineers at Lawrence Livermore Lab have developed a new 3D method that creates entire objects in one piece instead of building them up with layering.

Developed by LLNL in collaboration with UC Berkeley, the University of Rochester, and MIT, volumetric printing replaces layering with a process that creates the entire object simultaneously. It does this by using three overlapping lasers beamed in a hologram-like pattern into a transparent tank filled with photosetting plastic resin. A short exposure by a single beam isn’t enough to cure the resin in a short time, but combining three lasers can induce curing in about ten seconds. After the object is formed, the excess resin is then drained off to reveal the complete unit.

“The fact that you can do fully 3D parts all in one step really does overcome an important problem in additive manufacturing,” says LLNL researcher Maxim Shusteff. “We’re trying to print a 3D shape all at the same time. The real aim of this paper was to ask, ‘Can we make arbitrary 3D shapes all at once, instead of putting the parts together gradually layer by layer?’ It turns out we can.”

Volumetric printing is not only faster, but eliminates the need for temporary support structures, is more flexible, and provides more geometric flexibility. So far, it’s been used to create squares, beams, planes, struts at arbitrary angles, lattices, and complex, curved objects.

The process still has problems, as the article describes. Nonetheless, this is just one more step in the invention process that is making a Star Trek replicator possible.

Breakthrough Listen to observe Ourmuamua

10:47 am

Breakthrough Listen, one of billionaire Yuri Milner’s Breakthrough initiatives, is going to do an observation campaign of the interstellar object Ourmuamua using the Green Bank Radio telescope.

It has a highly unusual structure for an asteroid – an elongated cigar shape, hundreds of meters in length but with width and height perhaps only one tenth as long.

Researchers working on long-distance space transportation have previously suggested that a cigar or needle shape is the most likely architecture for an interstellar spacecraft, since this would minimize friction and damage from interstellar gas and dust. While a natural origin is more likely, there is currently no consensus on what that origin might have been, and Breakthrough Listen is well positioned to explore the possibility that ‘Oumuamua could be an artifact.

Listen’s observation campaign will begin on Wednesday, December 13 at 3:00 pm ET. Using the Robert C. Byrd Green Bank Telescope, it will continue to observe ‘Oumuamua across four radio bands, from 1 to 12 GHz. Its first phase of observations will last a total of 10 hours, divided into four “epochs” based on the object’s period of rotation.

If anything, this observation will provide us more information about Ourmuamua itself, which unfortunately is very limited because the object was already on its way out when it was discovered.

Lawsuit reveals two customers for Soyuz circumlunar tourist flight

8:50 am

Capitalism in space: A lawsuit against Space Adventures, the company that has previously organized tourist trips to ISS using Russian rockets, has finally revealed the names of the two individuals who had purchased tickets for a circumlunar flight around the Moon using a modified Soyuz capsule.

The details are included in a lawsuit now winding its way through U.S. District Court in Virginia. Harald McPike, a wealth Austrian investor and adventurer who resides in the Bahamas, has sued Space Adventures, its chairman and CEO Eric Anderson, and its president Thomas Shelley seeking to recover the $7 million down payment he put down on the flight in March 2013.

The other lunar tourist? The lawsuit says Space Adventures told McPike that it was Anousheh Ansari, who flew to the International Space Station (ISS) as a tourist in 2006 on a Soyuz in a deal the company brokered with the Russians. Ansari’s family also sponsored the $10 million Ansari X Prize won by Burt Rutan’s SpaceShipOne in 2004.

The dispute centers on McPike’s realization, after paying $7 million of the $30 million down payment, that Space Adventures probably could not deliver on its promises, mostly because of a Russian reluctance to sent tourists on such a mission. He wants his money back, and Space Adventures doesn’t want to return it.

While several modified Soyuz capsules, called Zond, were sent around the Moon during the 1960s, that was a very long time ago. Configuring the modern Soyuz for such a manned mission would require a lot of work, and I suspect the Russians didn’t want to do it without money up front. Moreover, I’m not even sure that the $300 million from the two tourists would have been sufficient.

Update on Russia’s troubled Sea Launch

8:35 am

Link here. It appears that the launch platform faces numerous additional obstacles before it can become operational again, including complex political maneuvering withing Russia and with Ukraine.

Yuzhmash officials [in Ukraine] gave their Russian counterparts at the S7 Group a list of components which are no longer available for the Zenit [rocket]. One of the most important items on the list is the ignition systems produced in the Lugansk region which has been taken over by pro-Russian rebels and remains practically cut off from the rest of Ukraine. The igniters burning black powder are used to initiate small solid-propellant motors which generate reverse thrust to facilitate the safe separation of the first and second stages during the ascent of the Zenit rocket to orbit.

According to industry sources, the S7 company has been so far unable to secure the delivery of Russian equivalents of the necessary hardware and materials, probably due to lack of permissions from Moscow. Instead, the S7 Group asked KB Yuzhnoe to organize the production of missing components in Ukraine. However, in the case of black powder, launching its production in Ukraine would not make economic sense due to lack of other applications beyond the very small amount required for the ignition systems, one source said.

Some observers question whether the S7 company has a real motivation to see the Sea Launch venture through because the airline with no prior experience in the space launch business ended up with the Sea Launch assets in its lap likely under pressure from the Kremlin. [emphasis mine]

S7 has also proposed using the Sea Launch platform to launch Russia’s next generation unmanned freighter, but this faces numerous technical issues. Regardless, the highlighted sentence above indicates how much the Russian government and the top-down Russian approach to everything interferes with efficient operations. It suggests that S7 didn’t buy into Sea Launch because it thought it could make money on it, but because of political pressure. Such pressure does not produce effective and profitable companies.

Blue Origin to resume New Shepard test flights next week?

3:41 pm

Capitalism in space: An FAA airspace notice published yesterday strongly suggests that Blue Origin will resume test flights of its New Shepard suborbital spacecraft next week.

The Notice to Airman, or NOTAM, published by the FAA on its website Dec. 9 closes airspace above Blue Origin’s test site between Dec. 11 and 14, from 9:30 a.m. to 4 p.m. Eastern each day. The closure is to “provide a safe environment for rocket launch and recovery.” The NOTAM does not give additional details about the planned activities, but does identify Blue Origin as the point of contact regarding the airspace closure.

The flight will test a new capsule and propulsion unit, as the vehicle that was test flown multiple times in the previous test flights has been retired. What is interesting is that the company says it is building more than one. This will give them a fleet which will allow them a rapid launch rate.

New Horizons successfully does course correction

8:54 am

New Horizons yesterday successfully fired its engines for 2.5 minutes to refine its course and January 1, 2019 fly-by of Kuiper belt object 2014 MU69.

The maneuver both refined the course toward and optimized the flyby arrival time at MU69, by setting closest approach to 12:33 a.m. EST (5:33 UTC) on Jan. 1, 2019. The prime flyby distance is set at 2,175 miles (3,500 kilometers); the timing provides better visibility for DSN’s powerful antennas to reflect radar waves off the surface of MU69 for New Horizons to receive – a difficult experiment that, if it succeeds, will help scientists determine the reflectivity and roughness of MU69’s surface.

The spacecraft will next be put in hibernation on December 21, and stay in that state until June.

Another Juno fly-by movie of Jupiter!

9:09 am

Cool movie time! Using 125 Juno images taken when it flew past Jupiter on its third orbit in December 2016, citizen scientist Gerald Eichstädt has produced a beautiful short movie showing that flyby. I have embedded it below.

At the link he provides very specific details on how he created this move. I found this detail however most fascinating:

Most repetitive bright and dark camera artifacts are patched. Due to the intense radiation near Jupiter, several additional bright pixels occured. Those aren’t patched in this animation.

In rarer cases, lightnings on Jupiter might also show up as bright pixels. [emphasis mine]

Major fund-raising effort for Japanese lunar mining company

8:58 am

Capitalism in space: The Japanese company behind Japan’s Google Lunar X-Prize finalist, ispace, announced this week a major effort in the coming weeks to obtain investment capital for its proposed lunar mining projects planned for the next decade.

ispace’s website indicates the next phase beyond the prize competition involves prospecting the moon between 2018 and 2023. Missions will include “mapping valuable resources…to determine economic value of resources. Our rover swarms are deployed on the Moon to scout crater and cave locations on the lunar poles that have a high probability of resource discovery,” the company says. In the third phase from 2024 to 2030, the company plans to “work with our strategic partners to collect, store, and deliver these valuable resources to our government, institutional, scientific, and private space customers.”

Whether its team can win the X-Prize however remains unclear, since it is dependent on the same PSLV launch that the Indian X-Prize team is buying, and that team still needs to raise $35 million to pay for the launch.

Rocket Lab delays test launch until Friday

11:25 pm

Capitalism in space: Rocket Lab’s second test launch of its Electron rocket has been delayed until Friday (U.S. time) to give the company more prep time.

Liftoff with three commercial CubeSat payloads was planned as soon as Thursday night, U.S. time, but officials said they needed more time.

The company transported the Electron vehicle to its launch base last month, after completing full-up hotfire testing. The launch team rehearsed countdown procedures last week, and practiced loading kerosene and liquid oxygen propellants into the rocket. “We did a hotfire campaign as a big preparatory test, so all that was done over a month ago,” said Shaun O’Donnell, Rocket Lab’s vice president of global operations. “The wet dress rehearsal went really well. It went really smooth, especially for our first run at it, so we’re really confident.”

Former Google Lunar X-Prize competitor still alive

8:26 am

Capitalism in space: Part Time Scientists, a Germany company partly sponsored by Audi that was formerly a competitor for the Google Lunar X-Prize, has reiterated its plans to land a privately-built and funded rover near the Apollo 17 landing site, and to do it careful so as to not damage the site’s historical significance.

The company has pledged its support to the organization For All Moonkind, which is dedicated to protecting the Apollo landing sites.

A review of the PTScientists website however provides little information on the company’s test schedule leading up to this lunar rover mission. I must therefore remain skeptical.

UAE invites its citizens to apply to join its astronaut program

9:51 am

The new colonial movement: The United Arab Emirates (UAE) today launched its astronaut program, inviting its citizens to apply for four positions that they hope to eventually fly to ISS.

Much of this effort is simply propaganda designed to push the UAE to diversify its economy and encourage aerospace development. Nonetheless, when SpaceX’s Dragon and Boeing’s Starliner are operational there will be nothing to prevent those companies from selling seats on them to the UAE, much as the Russians have done with tourists in the past. In fact, I expect this to happen.

Wall St pushes to have SpaceX save Tesla

9:36 am

Three articles in the news today illustrate both the corruption of the press as well as a desire of one analyst on Wall Street to convince Elon Musk to use his success at SpaceX to save Tesla.

All three news articles are based on a single recommendation made by one Morgan Stanley research analyst. Thus, the headline in the first article is an outright lie. There isn’t growing speculation, there is one guy with an opinion, an opinion by the way that Elon Musk doesn’t appear to share, according to the third article.

Musk said last year that there was too little cooperation between Tesla and Space Exploration Technologies Corp. to justify merging the two, dismissing the idea that had been raised by one of Jonas’s colleagues as “quite tenuous.”

From SpaceX’s point of view, combining these companies makes little sense. It would essentially be using the success of SpaceX to prop up Tesla’s financial weakness.

Musk of course controls both companies, and can do this if he wishes. If I was Musk, however, I would keep the companies separate, and let the chips fall where they may. Musk however might care enough about Tesla that he might want to save it, using SpaceX’s profits. If he does, however, he will instantly weaken SpaceX, as it will then no longer have as much cash available to pay for its future plans, such as the Big Falcon Rocket.

Private commercial supersonic jet gains funding

11:36 am

A private commercial supersonic jet company, Boom Supersonic, has gained significant investment funding since it first revealed its design concept in March.

Boom, whose suppliers include General Electric Co, Boeing, Honeywell International Inc and Netherlands-based TenCate Advanced Composites, has reportedly received 76 pre-orders from airlines, excluding the option of up to 20 aircraft from Japan Airlines. As of March 2017, the firm had raised about $41 million (£30.5 million) in funding.

Yoshiharu Ueki, president of Japan Airlines, added: ‘Through this partnership, we hope to contribute to the future of supersonic travel with the intent of providing more “time” to our valued passengers while emphasising flight safety.’

The firm has previously revealed that initial test flights for its 1,451mph (2,330kph) aircraft, nicknamed ‘Baby Boom’, will begin by the end of 2018.

Including the JAL preorder that makes 96 airplane sales total. It appears that this company is increasingly for real.

Calculating the number of alien space artifacts in our solar system

10:53 am

Link here. The author attempts to make a back of the envelope calculation of the number of abandoned alien interstellar spacecraft in the Milky Way (like our Voyager and Pioneer spacecraft), and from this calculate the number that might actually be drifting through the solar system. His conclusions?

Wondering if there’s any alien goodies in our solar system?

Well, the distance inner edge of the Oort cloud is estimated to be 4,000 A.U. This would make the volume of the solar system = 201 million cubic A.U.s, and the chance of an alien artifact adrift in our solar system (other than our own) is less than 1 in a 1,000,000. Using the outer edge distance for the Oort cloud at 50,000 AU = gives the volume of the solar system at 31.4 billion, with a slightly better than 1-in-45 chance.

But the nearest star system, Alpha Centauri is 4.4 light years distant, which equals a sphere 243 cubic light years in volume, with lots of elbow room for alien space junk!

The author also admits that these calculations depend on many assumptions, and should not be taken very seriously. Nonetheless, they are intriguing, and fun to consider.
