Scientists create coldest spot ever on ISS

5:29 pm

Using a compact lab called the Cold Atom Lab and launched to ISS in a Cygnus freighter in May, scientists have now successfully created coldest spot ever.

The government agency created atoms known as Bose-Einstein condensates (BECs) for the first time in orbit to focus on their unusual quantum behavior. A team of astronauts on the International Space Station (ISS) was able to take the Cold Atom Lab (CAL), which was loaded with lasers and a vacuum chamber, to understand how BECs interact with gravity.

…The scientists produced the BECs with temperatures as “as low as 100 nanoKelvin, or one ten-millionth of one Kelvin above absolute zero,” NASA added, in the statement. Zero Kelvin, also known as absolute zero, is the equivalent of minus 459 degrees Fahrenheit. The average temperature of space is approximately 3 Kelvin or minus 454 degrees Fahrenheit.

In a sense, they didn’t so much create a cold spot as create conditions that allowed the Bose-Einstein condensates to form so that they could study them. The article provides some background about this research, which is focused mostly on trying to figure out how to unify quantum mechanics (which explains the interactions at the atomic level) with general relativity (which explains the actions of matter and energy at large scales). Physicists have been trying unify both for decades, with little success.

Weird Martian crater?

1:17 pm

Weird crater on Mars

Time for another cool image! The image on the left, cropped to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on May 31, 2018, and shows a very strange layered mesa sitting in what looks like a crater or collapse feature. If you click on the image you can see the entire picture.

The location of this image is out in the middle of the vast northern plains of Mars. This region has few pronounced features, and generally sits at a lower elevation to the rest of Mars. It is suspected by some scientists that an intermittent ocean was once here, and that we are looking at the floor of a now dry sea.

This image was part of the July image release from MRO, and thus included no caption. They simply refer to it as a layered feature. It sits about a half mile (about 800 meters) to the west of a rough and indistinct cliff that drops down into an area of rougher terrain. This suggests that if this was formed by an impact, it cut down into that lower rougher layer, and since the impact there has been some upwelling from below creating the layered mesa.

I would not take my hypothesis very seriously, however. This feature could have nothing to do with an impact. It might also have been a mesa that now sits in a collapsed sinkhole. Or not. I could come up with many theories, all of which are likely wrong. What I do see here is something that geologically is very strange and baffling.

Company aims to sell its rocket engines to smallsat rocket companies

10:13 am

Capitalism in space: The new rocket engine manufacturer Ursa Major is aiming to sell its rocket engines to the new wave of smallsat rocket companies now emerging.

Ursa Major has taken up the challenge of trying to convince launch startups to outsource their engines rather than follow the models of SpaceX and Blue Origin. “The first gut response is ‘our engines are special and we don’t have a company without our engines,’ but if there is a way to increase their margin by flying someone else’s engines, most companies will be interested in coming around,” Ursa Major founder and CEO Joe Laurienti says.

Rocket Lab, Virgin Orbit and Vector Space Systems — three frontrunners fielding dedicated smallsat launchers — are building engines in house. Currently, just two launch startups — Generation Orbit and ABL Space Systems — have gone public with plans to depend on Laurienti’s 26-person team in Berthoud, Colorado, to supply the engines for the satellite launchers they’re developing.

That we now have companies that have successfully raised investment capital for both building rocket engines in-house for their own rockets as well buying them from independent subcontractors is firm proof that the upcoming boom in smallsat rockets is real, and very robust. The 20s should be a very exciting decade for rocketry.

Short of money, Planetary Resources to auction off equipment

10:02 am

Capitalism in space: Because its last fund-raising effort failed to hit its target, Planetary Resources is now auctioning off equipment from its headquarters.

The online auction will be conducted by James G. Murphy & Co. from Aug. 21 to 28, with a preview scheduled on Aug. 27 at Planetary Resources’ machine shop, lab and offices at 6742 185th Ave. NE in Redmond.

“We are preparing to sell some equipment that we’ve identified as not currently needed and easily replaceable,” Chris Lewicki, Planetary Resources’ president, CEO and chief asteroid miner, told GeekWire in an email. “This is a result of reducing overhead as we go forward with our smaller team.”

This could simply be an effort to maximize their financial resources as they reorganize. Nonetheless, it does not look good.

Rocket Lab signs deal with UAE company for 10 Electron launches

9:56 am

Capitalism in space: Rocket Lab today announced the signing of a 10-launch contract with Circle Aerospace, a new UAE satellite company.

The agreement sees Rocket Lab selected as the sole launch provider and primary provider of associated mission services for Circle Aerospace clients. Circle Aerospace missions will primarily launch from Rocket Lab’s private orbital launch site, Launch Complex-1, in New Zealand. Launches may also be conducted from Rocket Lab’s US launch site as required.

Circle Aerospace appears to be positioning itself as a smallsat manufacturer for others, but it is unclear at this point who its customers are. What is somewhat clear is that the company has deep pockets, either from private UAE oil money or government money (which are usually the same thing in the Arab Middle East).

Rocket Lab and Ecliptic agree to use Electron kick stage as a payload platform

10:07 am

Capitalism in space: Rocket Lab has struck a deal with Ecliptic Enterprises, the company that provides the on-board launch cameras for ULA and others, for using the Electron upper kick stage as a platform for payloads.

For those missions designated by Rocket Lab to accommodate hosted payloads, Electron’s capable kick stage, proven on the Electron’s first successful launch to orbit in January this year (“Still Testing”), will serve as the platform for one to several hosted payloads per mission, providing a structure for payload mounting, power, command and telemetry functions and attitude control. Ecliptic will deliver fully integrated hosted payloads to Rocket Lab for final integration onto Electron’s kick stage. Once in orbit, Ecliptic avionics will control all hosted payload operations and related data handling; Ecliptic will also manage the end-to-end mission service and experience for its customers. Ecliptic’s U.S. domestic and international customers will be from commercial and government sectors, as well as from academia, media and non-profit arenas.

This is fascinating. The whole reason the smallsat rocket industry is booming is because smallsat builders no longer wanted to be secondary payloads on the bigger rockets. They needed smaller rockets specifically catered to their needs as the primary payload. Because of this, Rocket Lab and Vector and a host of other smallsat rocket companies are now racing to fulfill that need.

Yet, Rocket Lab is now going to offer space on its tiny Electron rocket for even smaller secondary payloads. Ecliptic will act to sign up and coordinate the secondary payloads.

There is money to be made in space, and this competition to make it is creating opportunities for everyone. If you build a very small, very cheap cubesat in your garage, you likely can now go to Ecliptic to arrange to fly it on Rocket Lab’s Electron rocket.

True color images of Pluto and Charon

9:24 am

The New Horizons science team has released mosaic global images of Pluto and Charon, calibrated to capture their true colors as closely as possible.

These natural-color images result from refined calibrations of data gathered by New Horizons’ Multispectral Visible Imaging Camera (MVIC).”That processing creates images that would approximate the colors that the human eye would perceive – bringing them closer to ‘true color’ than the images released near the encounter,” said Alex Parker, a New Horizons science team co-investigator from Southwest Research Institute, Boulder, Colorado.

Because MVIC’s color filters don’t closely match the wavelengths sensed by human vision, mission scientists applied special processing to translate the raw MVIC data into an estimate of the colors that the eye would see. The colors are more subdued than those constructed from the raw MVIC color data, because of the narrower wavelength range sensed by the human eye.

Both images were taken as New Horizons zipped toward closest approach to Pluto and its moons on July 14, 2015; Charon was taken from a range of 46,091 miles (74,176 kilometers) and Pluto from 22,025 miles (35,445 kilometers). Each is a single color MVIC scan, with no data from other New Horizons imagers or instruments added. The striking features on each are clearly visible, from Charon’s reddish north-polar region known as Mordor Macula, to the bright expanse of Pluto’s, nitrogen-and-methane-ice rich “heart,” named Sputnik Planitia.

I must add that these images show only one hemisphere, since the New Horizons flyby did not get a good look at the opposite hemisphere. We won’t know what the other half of both planets look like for many decades.

The shrinking and growth of the poles of Mars

9:19 am

Using infrared data from several Mars orbiters over a period of a full Martian year, equivalent to two Earth years, scientists have created an animation showing the growth and retreat and regrowth of the carbon dioxide icecaps of the red planet’s two poles.

This animation shows a side-by-side comparison of CO2 ice at the north (left) and south (right) Martian poles over the course of a typical year (two Earth years). This simulation isn’t based on photos; instead, the data used to create it came from two infrared instruments capable of studying the poles even when they’re in complete darkness.

As Mars enters fall and winter, reduced sunlight allows CO2 ice to grow, covering each pole. While ice at the north pole is fairly symmetrical, it’s somewhat asymmetrical during its retreat from the south pole for reasons scientists still don’t understand. Scientists are especially interested in studying how global dust events affect the growth and retreat of this polar ice. Mars’ seasons are caused by a tilt in the planet, resulting in winter at one of the planet’s poles while it’s summer at the other.

I have embedded the animation below the fold.

Aristarchus Crater on the Moon

9:08 am

Aristarchus Crater

Cool image time! The image on the right, reduced in resolution to post here, shows Aristarchus Crater, one of the more geological intriguing locations on the Moon. This oblique image was taken by Lunar Reconnaissance Orbiter (LRO), still operating in lunar orbit. If you click on the image you can see the full resolution image.

Aristarchus crater is 40 kilometers (25 miles) in diameter and 2700 meters (1.7 miles) deep, with a central peak that rises 300 meters (almost a thousand feet) above the crater floor. When LRO pointed back towards the Sun, LROC was able to capture this magnificent view highlighting subtle differences in albedo (brightness). Some of the albedo contrast is due to maturity (young material is generally brighter than older material) and some reveal true differences in rock type. The central peak shows the complexity of what lies beneath the now hardened impact melt sea that filled the bottom of the crater.

The best part however is the close-up they provided of the crater’s central peaks, posted below.

Tess captures comet, variable stars, asteroids, and Martian light

8:44 am

During its testing period prior to beginning science operations this month, the exoplanet space telescope TESS spotted in one series of images a comet, a host of variable stars, some asteroids, and even the faint hint of some reflected light from Mars.

Over the course of these tests, TESS took images of C/2018 N1, a comet discovered by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) satellite on June 29. The comet, located about 29 million miles (48 million kilometers) from Earth in the southern constellation Piscis Austrinus, is seen to move across the frame from right to left as it orbits the Sun. The comet’s tail, which consists of gases carried away from the comet by an outflow from the Sun called the solar wind, extends to the top of the frame and gradually pivots as the comet glides across the field of view.

In addition to the comet, the images reveal a treasure trove of other astronomical activity. The stars appear to shift between white and black as a result of image processing. The shift also highlights variable stars — which change brightness either as a result of pulsation, rapid rotation, or by eclipsing binary neighbors. Asteroids in our solar system appear as small white dots moving across the field of view. Towards the end of the video, one can see a faint broad arc of light moving across the middle section of the frame from left to right. This is stray light from Mars, which is located outside the frame. The images were taken when Mars was at its brightest near opposition, or its closest distance, to Earth.

The video that was compiled from these images is embedded below the fold.

SpaceX launches commercial satellite with first used Block 5 first stage

8:34 am

Capitalism in space: Last night SpaceX successfully placed a commercial communications satellite into orbit using a previously flown Block 5 first stage.

The turnaround for this first stage was only a little over two months. It successfully landed on the drone ship in the Atlantic, and they plan to fly it a third time later this year. You can watch the launch here.

The leaders in the 2018 launch race:

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

China still leads the U.S. 22 to 21 in the national rankings.

Want to earn a college degree in mining in space? You can!

2:12 pm

Capitalism in space: Link here.

Classes begin Aug. 20 for the first 35 students enrolled in the program. With courses held online, students around the world can earn a post-baccalaureate certificate, master’s degree, or doctorate focused on finding and pulling resources from space.

Many asteroids and nearby planets contain rare platinum-group metals and industrial metals like iron and nickel that are needed for building exploration infrastructure. Right now, though, the most sought-after resource in space is one that is actually quite abundant on the Blue Planet. “If you think about it, water in space would be the oil of space, because that is going to power and transport, give us energy, enable the whole space economy and allow us to keep going further and further,” Abbud-Madrid said. “Such an elemental product as water would be the first one we go after.”

It can be argued that this is premature. It can also be argued that the time is coming, and knowing more about the resources in space can be an advantage in the competitive free market.

How to build a scaled-down version of Curiosity, all by yourself!

9:50 am

JPL has released open-source plans for building a scaled down version of the rover Curiosity at a total cost of only $2,500.

This project is a successor to an earlier educational rover model called “ROV-E,” which received positive responses in schools and museums, NASA said. The Open Source Rover offers a more affordable, less complicated model, and according to agency officials, people can assemble the new model with off-the-shelf parts for about $2,500.

“While the OSR [Open Source Rover] instructions are quite detailed, they still allow the builder the option of making their own design choices,” JPL officials said. “For example, builders can decide what controllers to use, weigh the trade-offs of adding USB cameras or solar panels and even attach science payloads. The baseline design of OSR … will allow users to choose how they want to customize and add to their rover, touching on multiple hardware and software principles along the way.”

I wonder how heavy a home-built rover would be, and whether it could be launched on a Falcon Heavy to Mars.

Chandrayaan-2 delayed again, until January 2019

9:13 am

The new colonial movement: ISRO, India’s space agency, has revealed that the launch of its lunar rover/lander Chandrayaan-2 has been delayed from October to Janaury 2019.

Dr M Annadurai, Director of U R Rao Satellite Centre confirmed to NDTV that the launch date for Chandryaan-2 “is slipping to 2019” from the initially planned launch in October this year.

Dr Annadurai said that India’s moon mission now aims to land in February and the rocket launch will take place in January next year.

Moreover, since the weight of the Chandrayaan-2 satellite has increased, Dr Annadurai said that now instead of GSLV MK-II, GSLV MK-III will be used. Geo-synchronous Satellite Launch Vehicle MK-III (GSLV MK-III), also called the ‘The Bahubali’, is India’s heaviest rocket that weighs nearly 640 tons and will be used to hoist the Chandrayaan-2 satellite from India’s rocket port at Sriharikota.

It appears that in building the spacecraft they have not been able to keep its weight low enough, and have been forced to switch launch vehicles, with this switch causing the delay.

The article also provides a tidbit of information about the GLSV MK-III rocket, that they have an real name for it, Bahubali. If so, they should use it. It sells much better than GLSV MK-III.

Another failed drilling attempt by Curiosity

9:38 am

The second attempt by Curiosity to drill into Vera Rubin Ridge was a failure, the rock once again being too hard using the rover’s new improvised drilling technique.

They are now in search of “softer rock.” The scientists very much want to get at least one drill hole in the hematite unit on Vera Rubin Ridge. However, it does appear that the new drill technique, that uses the robot arm to push the drill bit down as its drills, does not provide enough force for some hard geological features.

The failure to drill is in itself not a complete scientific washout. Knowing the hardness of a rock can tell a geologist a great deal about it. Nonetheless, the Curiosity science team seems determined to find something they can drill into on Vera Rubin Ridge.

Mars dust storm blocks Mars Reconnaissance Orbiter images

9:29 am

In my normal routine to check out the periodic posting of new high resolution images from Mars Reconnaissance Orbiter (MRO), the August 1 update brought what at first was a disturbing surprise. If you go to the link you will see that a large majority of the images show nothing by a series of vertical lines, as if the high resolution camera on MRO has failed.

Yet, scattered among the images were perfectly sharp images. I started to look at these images to try to figure out the differences, and quickly found that the sharp images were always of features in high latitudes, while the blurred images were closer to the equator.

The August 1 image release covered the June/July time period, when the on-going Martian dust storm was at its height. The images illustrate also where the storm was most opaque, closer to the equator.

The next few updates, which occur every three weeks or so, should show increasing clarity as the storm subsides. And the storm is subsiding, according to the latest Opportunity update. The scientists have still not re-established contact with the rover, and do not expect to for at least a month or more, but they are finding that the atmospheric opacity at Endeavour Crater seems to be dropping.

More close-up images of Ceres

9:19 am

Dome and fractures in Occator Crater

Strange image time! The Dawn science team today released a set of new images taken by the spacecraft in its new very close orbit of Ceres. The image on the right is a cropped section of one of those images, and shows some fractures and a dome in Occator Crater. The image was taken from 28 miles altitude, and if you click on it you can see the entire photograph.

What immediately stands out in this image is the strange bright flow on top of the dome. At first glance it looks like someone put a seashell there. In reality I think it is showing us a landslide of bright material flowing downward, towards the top of the image. The flow was significant enough that it piled up as it went down, which is why it created a cliff edge and shadow line at its base.

Everything we see here is influenced by Ceres’s tiny gravity. It is not unusual to see fractures in the floor of a crater, the nature of these fractures and domes is different, and will require a lot of work by scientists to interpret, because of the different environment.

No water as yet detected on Ryugu

9:05 am

The Hayabusa-2 science team today said that their first preliminary survey of Ryugu has yet to detect evidence of water.

The Japan Aerospace Exploration Agency (JAXA) said Aug. 2 that data collected from the space probe showed no water on the boulders scattered on the surface of Ryugu.

Ryugu is a C-type asteroid, which is rich in carbon. Many C-type asteroids are known to contain moisture in their surface boulders, and experts hoped that Ryugu would be one of them.

Hayabusa-2’s visit has just begun. I still expect surprises.

NASA announces crews for first commercial manned launches

9:00 am

NASA has announced the crews for the first commercial manned launches.

Boeing’s crew flight test aboard its Starliner spacecraft, which is targeted to launch in mid-2019, will have Eric Boe, Chris Ferguson and Nicole Mann on board. Boeing’s first post-certification mission will have Josh Cassada and Suni Williams aboard.

SpaceX’s demo mission 2 aboard its Crew Dragon spacecraft, which is targeted to launch in April 2019, will have Bob Behnken and Doug Hurley aboard. The first post-certification mission will be crewed by Victor Glover and Mike Hopkins.

These crews cover the first two manned missions for each spacecraft.

New launch dates for commercial crew posted by NASA

2:26 pm

NASA has now released an updated schedule for the first test flights of Boeing’s Starliner and SpaceX’s Dragon manned capsules:

In chronological order:

SpaceX Demo-1 (uncrewed): November 2018
Boeing Orbital Flight Test (uncrewed): late 2018 / early 2019
SpaceX Demo-2 (crewed): April 2019
Boeing Crew Flight Test (crewed): mid-2019

Note once again that this schedule bears no resemblance to the pessimistic schedule put forth by the GAO. That schedule indicated that significant delays could be expected because of NASA’s heavy paperwork requirements.

I fully expect that political needs will force that paperwork to be done much faster than the GAO, or NASA, expects, or even wants. And the increased speed will have little to do with reducing safety.

Landslide on Mars

12:45 pm

Landslide on Mars

Cool image time! The image on the right, cropped and reduced in resolution to post here, was taken by Mars Reconnaissance Orbiter on May 30, 2018. It shows the remains of a landslide where it appears a huge chunk of the cliff face broke off and then flowed downward, pushing ahead of it more material to produce a tongue of debris more than four miles long. (If you click on the image you can see the full photograph.)

The picture invokes a spectacular single event. When the cliff broke off, it hit the ground below it like a rock would in wet beach mud. Like wet sand, the ground was pushed away in a muddy gloppy mess.

Is this terrain wet however? The location of this landslide provides some intriguing geological context. Below are two context images, showing this landslide’s location on Mars.

Private rocket failure in Alaska

9:19 am

Capitalism in space: A suborbital test launch of a private company on July 20 likely failed almost immediately after launch.

On July 20, the California-based company Astra Space carried out a suborbital launch of its “Rocket 1” from the Pacific Spaceport Complex on Kodiak Island in Alaska. The rocket took off in foggy conditions, so there wasn’t much to see, but the launch could still be heard, according to local reporter Gabe Stutman. But other than the fact that Rocket 1 launched, no one seems to know what happened next.

The Federal Aviation Administration (FAA) said, in a statement to SpaceNews, that the rocket “experienced a mishap.” Many have taken this to mean that, at some point after the rocket launched, it failed in some way. But Craig Campbell, president of Alaska Aerospace, which operates the launch site, told SpaceNews that Astra Space is “very pleased” with how the launched turned out.

I must admit that I completely missed this event, when it happened. However, it appears that the company experienced some form of failure, not unlike what happened to the recent launch of Interstellar’s MOMO rocket. Since this is a test launch, even a failure is of value however, as it can tell them what is wrong with their rocket.

Boeing adjusts Starliner launch schedule after fuel leak during test

8:56 am

Capitalism in space: Yesterday Boeing pushed back its Starliner launch schedule as a result of the fuel leak problem that had occurred during an engine test of the capsule last week.

They now plan the first unmanned test flight around the end of this year, with the first manned flight in the middle of 2019.

As for the fuel leak,

several abort engine valves failed to close properly, causing a leak of toxic fuels. The test article was not damaged and no one was hurt, but the incident required an investigation with support from NASA.

Other reports say that 4 of 8 valves failed to close. There is no explanation about why this happened, but I find it a very strange technical failure. Building valves for spacecraft is not cutting edge design, or I wouldn’t think so.

Tomorrow NASA administrator Jim Bridenstine is going to make an announcement with some official launch dates for both Boeing and SpaceX. We shall see if SpaceX’s schedule gets pushed back as well.

Close-up of bright spot in Occator Crater

3:35 pm

Vinalia Faculae in Occator Crater

Cool image time! The Dawn science team today released some new images taken by the spacecraft in its final tight orbit around the dwarf planet Ceres. The image on the right is a cropped section of the full image. It shows some interesting details of part of one of the two bright spots in Occator Crater, dubbed Vinalia Facula, and was taken from a distance of 36 miles.

Other images show small bright spots in another small crater, fractures and interesting patterns in the floor of Occator crater, a dome in Occator Crater suggestive of underground processes pushing up, and other close-ups of its crater walls.

While all of these features are reminiscent of geology on Earth, none are really the same. Ceres’ light gravity and harsh environment, plus its history in the asteroid belt, requires alien processes that only hint at similarities to what we see on Earth.

NASA safety panel reviews commercial crew, tries to justify its paperwork demands

9:35 am

Link here. The article describes the results from the quarterly meeting of NASA’s safety panel, which occurred last week, including its concerns about the recent test problems during a launch abort test of Boeing’s Starliner capsule. It also describes the panel’s general satisfaction at the status of SpaceX’s Dragon capsule.

The article however ends with a long screed by one panel member, explaining that the heavy paperwork requirements they are imposing on the two companies is not really paperwork.

“It needs to be noted by everyone, and we’re especially interested in making sure that all of the external stakeholders realize this, that while the concluding process of certification has sometimes been described as a paper process, that is really just a shorthand clarification and in reality it could not be further from the truth,” noted Dr. McErlean.

In reality, the process is as follows. “In a certified design, the design agent – the contractor or partner in this case – performs the design and in the certification plan, the design agent and the certification agency (NASA) agree on the submittal of certification evidence.

“This could be measurements, it can be test data, it can be analysis, but it almost always involves the submittal of detailed technical data, not simply paper descriptions or forms. Sometimes it involves witness testing and sometimes it involves physical inspection. But it almost always wraps around important technical submittals.

Can I translate? The safety panel requires a lot of testing so that a lot of paperwork can be filled out. And while much of this testing is likely to help make the capsule’s safer, most of it seems to me to be make-work, and designed to justify the existence of NASA and its safety panel.

Russian company that builds Proton rocket faces bankruptcy and reorganization

9:25 am

The Russian company that builds Russia’s Proton rocket now faces bankruptcy and reorganization.

By the middle of 2018, due to the dramatically slowed down rate of Proton launches, its manufacturers fell deeper into the red and needed federal funding to stay afloat. According to the official numbers, GKNPTs Khrunichev lost 23 billion rubles in 2017 and asked for a 30-billion infusion of cash from the government.

At the end of June, the Head of Roskosmos Dmitry Rogozin acknowledged an ongoing effort to fix the financial situation at Khrunichev and announced plans to accelerate the switch of the Russian launch operations from the Proton to the Angara family. Ironically, Roskosmos exacerbated the company’s debt with its penalties for missed production deadlines, even though Russian payloads slated to ride those delayed rockets were themselves years behind schedule and GKNPTs Khrunichev had no room to store large rocket components.

In an effort to raise capital, Khrunichev planned to sell a big part of its campus, located in the hyper-valuable real estate area of Moscow, to private developers. In the process, the company would also dramatically reduce its production capacity and cut its personnel in the Russian capital, shifting key manufacturing operations to Omsk, in Western Siberia. In another cost-saving measure, around 200 people were reported to be marked for layoffs at Proton’s launch facilities in Baikonur beginning in the fall of 2018.

The Russian government, rather than allow for competition, is working to prop the company up. So, rather than having new companies appear with new and better ideas, Russia will be saddled with an old company not good at innovating.

NASA rubberstamps Russian engines in Atlas 5 for manned flights

9:18 am

Surprise surprise! NASA has certified the Russian engines used in the Atlas 5 as safe for manned flights.

NASA had been claiming that, because it cannot observe every detail in how Russia builds the engines, it cannot certify them as safe for manned flight. This is, and has been, crap. The Atlas 5, with this engine, has been one of the most reliable rockets ever built.

In truth, what NASA’s bureaucracy was really doing was using these Russian engines as a wedge to slow down Boeing’s first manned flight, mainly because the commercial crew program is threatening NASA past monopoly on U.S. manned flight. Once privately built rockets and manned spacecraft fly, people are suddenly going to realize we don’t really need NASA.

Watch SpaceX retract one leg from used Block 5 booster

12:42 am

For geeks only! The video below the fold shows the new equipment that SpaceX has developed to retract the open legs of a used Block 5 booster. This video shows them attaching the booster in a secure vertical position, then attaching cables to the base of the first leg which are then used to retract it back into its launch position against the side of the booster. The design is quite clever.

The design also shows how primitive the art of reusable rockets remains. Though SpaceX has clearly succeeded in simplifying and automating this process, it remains slow and complex. In time this will get easier, but right now, this remains state of the art.
