Booking service now available to rocket and satellite companies

9:41 am

Capitalism in space: A new company, Precious Payload, is now offering a booking service to both rocket companies and satellite manufacturers to make it easier to match them together.

In the Precious Payload concept, launch providers and brokers share and exchange their immediate and future availability of inventory with the independent Precious Payload GDS, including the status of reservations of inventory (eg. available, reserved, booked, etc.).

Anyone who wants to launch a satellite uploads their mission profile into the Precious Payload GDS. A special algorithm then analyses the data and shows the real-time availability of launchers for specific types of mission.

Launch providers, both manufacturers and brokers, can benefit from the Precious Payload GDS by being able to open another sales channel for their core businesses. They not only receive and process the booking requests from satellite companies, but also browse through the backlog of satellites waiting for launch and bid for their business. Advanced services like rebooking the launches and effectively managing client cancellations and launch failures raise the bar for customer experience in the market.

To pitch their product, they are presently offering their initial service for free.

Next test flight of Rocket Lab’s Electron rocket delayed

9:34 am

Capitalism in space: Rocket Lab has revealed that the second test flight of its rocket Electron is still several months away.

Rocket Lab is in the early stages of a three-vehicle test programme and Moon Express is still developing its lander at its facilities at Cape Canaveral, from where Apollo missions were launched. Rocket Lab’s first test launch successfully made it to space in late May. The first stage performed as it should but the second stage failed to deliver the payload to orbit.

Results of data analysis from the test flight could be available some time next week.

Earlier this month Rocket Lab founder Peter Beck said the company and its investors had confidence in the programme and they had another five rockets in various stages of production.
Beck said then a second test launch was about two or three months away and the company hoped to get its commercial launches underway as soon as it was satisfied with the test programme.

The company had previously said it hoped to launch the second test flight in mid-2017. It appears now that the second launch will not happen before October.

The article is strangely focused on selling the idea that Moon Express’s Google Lunar X-Prize flight, which must occur by the end of this year, is still on track. I don’t see how, with this news. Rocket Lab must first complete its three test flights, and I don’t see how they can do this, get their results, and update their engineering and still get this first commercial flight off by December.

Solid gold Apollo 11 lunar module replica stolen from Armstrong museum in Ohio

9:23 am

On Friday thieves broke into the Neil Armstrong Museum in Ohio and stole a solid gold miniature replica of the Apollo ll lunar module that had been one of three gifted to the three astronauts in Paris during their post-flight world tour.

Police responded to a burglary alarm at the Armstrong Air and Space Museum in Wapakoneta, Ohio, shortly before midnight on Friday (July 28), where the 18 karat gold, five-inch-high (13 centimeter) miniature lunar lander was found missing. “Entry to the museum was discovered and taken was a solid gold replica of the 1969 Lunar Excursion Module that landed on the moon,” Russel Hunlock, Wapakoneta police chief, stated in a release. “The piece is very rare as it was presented to Neil Armstrong in Paris, France shortly after the moon landing.”

I am not hopeful the replica will be recovered. It was obviously stolen for its gold, and I would expect the thieves to quickly break it apart and melt the gold down for sale.

Japanese private rocket launch terminates early due of communication failure

9:14 am

Capitalism in space: The first launch of the first privately-built and funded Japanese suborbital rocket was terminated early today because of a communications failure.

The rocket’s developers, Interstellar Technologies, said they aborted the launch after about 80 seconds and it landed about 8 kilometers (5 miles) offshore. The aim had been to launch the rocket, called “Momo,” to an altitude of 100 kilometers (62 miles), but it only traveled about 30-40 kilometers (19-25 miles).

The Great Red Spot

9:43 am

The Great Red Spot

Cool image time! The image on the right, reduced in resolution to post here, shows one of the close-ups taken by Juno during its recent close fly-by of the Great Red Spot. What makes it different is its colors.

This image of Jupiter’s iconic Great Red Spot was created by citizen scientist Björn Jónsson using data from the JunoCam imager on NASA’s Juno spacecraft.

This true-color image offers a natural color rendition of what the Great Red Spot and surrounding areas would look like to human eyes from Juno’s position. The tumultuous atmospheric zones in and around the Great Red Spot are clearly visible.

Normally scientists enhance the colors to bring out the details. This version does not, which definitely makes it a little less dramatic but more accurate. Even so, the whirls and storms within the Spot are clearly visible.

The image was taken on July 10 from about 8,600 miles away. Note also that the entire Earth would fit inside the storm.

SpaceX now one of the world’s most valuable companies

9:37 pm

Data from a new round of investment capital fundraising says that SpaceX is now valued at $21 billion, placing it among the only six venture-backed companies worth more than $20 billion.

The article also notes that this new valuation is up from the $12 billion listed only two years ago.

Update: As noted by my readers, I have revised the post to note that this story refers not to all companies but to those that obtained their financing privately.

Video of Iranian launch today

9:22 pm

The Iranians have released video of today’s rocket launch.

I’d love a translation of what the crowd is chanting. I would also encourage the engineers in my readership to look at this and tell me if the launch looks right, and if there is any way to judge whether it is an rocket for orbital satellites or a missile. We still have no evidence the rocket successfully put anything in orbit.

Meanwhile, the Trump administration has called this launch a breach of a UN resolution forbidding Iran from developing ballistic missiles.

Cameras on next Kepler-like exoplanet space telescope out of focus

9:34 am

NASA has revealed that the cameras on the Transiting Exoplanet Survey Satellite (TESS) become slightly out of focus when they are cooled to -75 Celsius, the temperature they will experience in space.

NASA has also decided that the fuzziness is not enough to require a fix, and is proceeding with the mission as is, despite concerns expressed by scientists.

Alan Boss, an astronomer with the Carnegie Institution, brought up the issue in a summary of a meeting last week of the Astrophysics Advisory Committee, of which he is a member. “That could have some big effects on the photometry,” he said of the focus problem. “This is certainly a concern for the folks who know a lot about photometry.”

TESS will use those cameras to monitor the brightness of the nearest and brightest stars in the sky, an approach similar to that used by Kepler, a spacecraft developed originally to monitor one specific region of the sky. Both spacecraft are designed to look for minute, periodic dips in brightness of those stars as planets pass in front of, or transit, them. Chou said that since TESS is designed to conduct photometry, measuring the brightness of the stars in its field of view, “resolution is less important compared to imaging missions like Hubble.” However, astronomers are concerned that there will be some loss of sensitivity because light from the stars will be spread out onto a slightly larger area of the detector.

“The question is how much science degradation will there be in the results,” Boss said. “The TESS team thinks there will be a 10 percent cut in terms of the number of planets that they expect to be able to detect.”

It could be that NASA has decided that the cost and delay required to fix this is not worth that 10% loss of data.

Time/PBS video documentary nominated for Emmy despite factual error in title

9:25 am

Fake news: The Time/PBS video documentary A Year in Space has been nominated for an Emmy award, despite a blatant factual error in the show’s title.

I haven’t seen the documentary, and so it might a great achievement. Nonetheless, this mission only lasted 340 days, not a year, and to call it “a year in space” is not only false, but an outright lie. For a news organization to start out this wrong, in the title, and then for it to get an Emmy nomination, tells us a great deal about the standards of accuracy in television news.

Breakthrough Starshot puts smallest satellites ever into orbit

9:18 am

Breakthrough Starshot, the privately funded $100 million effort to launch a probe to the nearest star, has put into orbit the world’s smallest satellites ever.

The six prototypes, dubbed Sprites, weigh only 4 grams and contain solar panels, computers, sensors, and radios on a surface equal to that of a U.S. postage stamp. Developed by researchers at Cornell University and transported into space as secondary payloads on a rocket built by the Europe-based company OHB System AG, the nanosatellites are being tested for electronics and communication performance in orbit.

The significance here is not so much that this advances the project’s interstellar mission, but that this technology is becoming more likely for use on both commercial and planetary spacecraft.

Commercial lunar mission gives launch contract to ULA

5:56 pm

Capitalism in space: Astrobotic, a private company planning to put a lander on the Moon by 2019, has awarded its launch contract to ULA.

This initial Peregrine lunar lander will fly 77 pounds (35 kilograms) of customer payloads from six nations either above or below the spacecraft’s deck, depending on specific needs. The autonomous landing will use cameras, guidance computing and five Aerojet Rocketdyne-made hypergolic engines to set the lander down on four shock-absorbing legs.

It will stand 6 feet tall (1.8 meters) and have a diameter of 8 feet (2.5 meters).Subsequent missions envision scaling up to payload masses of 585 pounds (265 kilograms). Markets range from scientific instruments to placing mementos on the Moon.

This company had been competing for the Google Lunar X-Prize, but pulled out of the competition when it realized it couldn’t launch by the end of 2018. It continued development, however, and apparently has gathered enough customers to pay for its launch in 2019.

TDRS-M launch moved to August 20

5:47 pm

NASA has decided to delay the launch of its TDRS-M satellite until August 20.

This simplifies their launch schedule, as it allows SpaceX to launch as planned on August 12 and thus not interfere with an August 17 Russian spacewalk that is releasing two satellites from ISS. It will also give them plenty of time to replace the antenna that was damaged during launch prep, in an incident which they still have not described in any detail.

The damage and repair of TDRS-M creates complicated scheduling problems

9:10 am

Because of the launch delay caused by the accident that damaged the antenna of NASA’s TDRS-M communication satellite, requiring its replacement, the agency is now faced with a cascading series of scheduling problems.

They are now aiming for an August 10 launch of TDRS-M on a ULA Atlas 5. This will then force a delay in the August 12 launch of a Dragon capsule to ISS to August 14, which can’t be delayed past August 16 because of a scheduled Russian spacewalk on ISS that must happen on August 17 because it involves the release of two satellites. Making things even more complicated is Dragon’s cargo, which includes mice for a rodent experiment. If it doesn’t occur before August 16, the mice will then have to be replaced with fresh mice, causing further delays.

There is then even the chance that these scheduling problems might impact SpaceX’s scheduled August 28’s launch of the X-37B, as well as ULA’s scheduled August 31 launch of surveillance satellite.

One additional tidbit: This Dragon will be the last unused cargo capsule. All future SpaceX cargo missions will use previously flown capsules.

I should add that these scheduling issues illustrate starkly the growing need for more launch sites. There is money to be made here, fulfilling this need.

Interorbital’s first test rocket, Neptune 1, is almost ready for flight

8:56 am

Capitalism in space: Interorbital, a smallsat rocket company building what they hope will be the world’s smallest and cheapest rocket, have announced that their first test rocket, Neptune 1 Guidance Test Vehicle (N1 GTV), is nearing completion.

During the test flight, the rocket will simulate an orbital launch trajectory by using the main rocket engine’s throttling capability to vary the thrust-to-weight ratio, thus simulating the actual conditions that will be experienced during an orbital launch. After the rocket passes through the transonic phase and Max Q, the engine will gradually throttle down, slowing the rocket until it begins to hover. At this point, the rocket engine will be shut down and the rocket will be allowed to fall. At a safe altitude, a parachute will be deployed for vehicle and payload recovery.

They then plan to follow this with an orbital test flight. No dates however for any of these test flights have as yet been announced.

The endless bands of Saturn

9:39 am

Cool image time. One of the images released by the Cassini science team this week when it announced the first results from the spacecraft’s weekly dives between Saturn and its innermost rings was a short video made from 137 images taken on its first dive on April 26, 2017.

It is absolutely worthwhile to view this video. It begins at Saturn’s north pole, looking down into what appears to be a bottomless vortex, and continues south to almost the equator. Along the way the movie captures what seems to be innumerable horizontal bands across the gas giant’s surface. Not only are do we see the major bands that have been observed from Earth for centuries, there are bands within bands, and bands within those bands. Like a fractal it appears that the deeper you go, the more horizontal jet streams you see.

Like Juno at Jupiter, the mysteries of a gas giant like Saturn is overwhelming. This is a big and very active planet. We understand almost nothing about its weather systems, its atmosphere, and its interior. And this glimpse by Cassini is only that, a mere glimpse. When Cassini’s mission ends in September, it will leave us a treasure trove of knowledge. It will also leave us a much larger library of unanswered questions, all of which will remain unanswered until we can return, decades hence, with new probes..

Tupperware in space!

9:20 am

Capitalism in space: Tupperware and NASA have partnered to provide space-grown gardens an artificial material for roots to grow and be watered.

First flown to the ISS in 2014, the Vegetable Production System, (aka the “Veggie” facility), is an experiment for growing plants in zero gravity in a plastic greenhouse. It consists of a collapsible plastic tent with a controllable atmosphere lit by red, blue, and green LED lamps to promote growth. Since dirt and space travel don’t mix, the seeds are embedded in rooting “pillows” that take the place of soil to retain water and give the roots somewhere to grow.

The problem is that the pillows don’t hold onto water very well, so the hydroponic system keeps drying out unless it’s tended regularly. Given how much it costs to keep an astronaut on the station, time spent watering the lettuce is about as economical as hiring a brain surgeon to mow the lawn, so a team led by Howard Levine at the Kennedy Space Center is working on some upgrades for the system.

One key example is the semi-hydroponic Passive Orbital Nutrient Delivery System (PONDS) being produced by Tupperware. With over 75 years of experience working with food-grade plastics as well as injection molding and other plastic manufacturing processes, Tupperware is producing a new disposable pillow made of plastic mesh that uses capillary forces and unusual geometries to replace gravity and hold water in like a zero gravity sponge while permitting root formation.

In other words, rather than design and built the pillows itself, as it would have in the past, NASA has hired Tupperware to build them. I am willing to bet this is saving NASA both time and money.

New Horizons team spots stellar eclipse by 2014 MU69

9:14 am

In an effort to learn as much as possible about New Horizons’ next target, Kuiper belt object 2014 MU69, the science team has successfully observed on July 17 a 0.2-second-long eclipse of a star by that object.

This was the third occultation by 2014 MU69 that the science team attempted to catch. With the first, on the ground, they saw nothing. The second, using the flying observatory SOFIA, was more successful, as was the third attempt last week.

Though they haven’t yet released their findings, they say the data from the last two observations has allowed them to determine the rough shape and size of 2014 MU69. This is crucial information needed for planning the observations of it during New Horizons January 1, 2019 fly-by.

Another space company partners with Luxembourg

9:03 am

Capitalism in space: Luxembourg has formed a new business partnership with Magna Parva, a United Kingdom company, to develop in-space manufacturing technology.

Within the framework of this MoU, the developments and research to take place in Luxembourg are related to the project for in-space manufacturing of composite beams equipped with antennas. Kleos Space will collaborate with EmTroniX, a Luxembourg-based company specialized in electronics development, as well as with the Luxembourg Institute of Science and Technology (LIST) on this subject. The Government will support the development of the in-space manufacturing technology by providing funding through the Luxembourg space program (LuxIMPULSE).

I suspect the manufacturing will be some form of 3D printing. However, it is unclear to me where in space this manufacturing will take place. Will it occur on ISS or the Chinese space station expected to launch in a few years? Or is Luxembourg planning some new venture that either includes some privately built station (Bigelow?) or an unmanned robot in orbit?

Either way, Luxembourg is once again investing its tax revenue in what it thinks will be profitable endeavors in space, and that venture capitalism is continuing to attract companies to that nation.

Brooks and Dunn – Only in America

6:01 pm

An evening pause: In honor of what happened today, 48 years ago, when three American astronauts safely landed home on Earth, after walking on the Moon. From the chorus:

Only in America
Dreamin’ in red white and blue
Only in America
Where we dream as big as we want to
We all get a chance
Everybody gets to dance

It will be the American ideas of freedom, individual achievement, and capitalism that will make the settlement of the solar system possible. Other nations will participate, but it will still be these ideas that fuel the journey.

First results from Cassini’s dives between Saturn and its rings

11:35 am

The first results from Cassini’s weekly dives between Saturn and its innermost rings have now been released.

The big surprise so far is the lack of a tilt to Saturn’s magnetic field.

Based on data collected by Cassini’s magnetometer instrument, Saturn’s magnetic field appears to be surprisingly well-aligned with the planet’s rotation axis. The tilt is much smaller than 0.06 degrees — which is the lower limit the spacecraft’s magnetometer data placed on the value prior to the start of the Grand Finale.

This observation is at odds with scientists’ theoretical understanding of how magnetic fields are generated. Planetary magnetic fields are understood to require some degree of tilt to sustain currents flowing through the liquid metal deep inside the planets (in Saturn’s case, thought to be liquid metallic hydrogen). With no tilt, the currents would eventually subside and the field would disappear.

Any tilt to the magnetic field would make the daily wobble of the planet’s deep interior observable, thus revealing the true length of Saturn’s day, which has so far proven elusive.

They also have gotten lots of much better images of the planet’s cloud tops.

NASA and Lockheed Martin to build simulated interplanetary spaceship, on the ground

9:53 am

Yawn. NASA and Lockheed Martin have partnered to re-purpose a leftover shuttle cargo module into a ground-based simulated interplanetary spaceship.

Lockheed Martin announced it will refurbish the Donatello multi-purpose logistics module (MLPM), transforming from it from its original, unrealized role as a supply conveyor for the International Space Station to a test and training model of a living area for astronauts working beyond Earth orbit. The work is being done under a public-private partnership between the aerospace corporation and NASA. “We are excited to work with NASA to repurpose a historic piece of flight hardware,” said Bill Pratt, Lockheed Martin’s program manager for the deep space habitat contract, in a statement.

…Over an 18-month period, Lockheed Martin will build upon its deep space habitat concept it developed during the first phase of NASA’s Next Space Technologies for Exploration Partnerships, or NextSTEP, program by using virtual and augmented reality prototyping in an effort to reduce costs and schedule, as well as identify and address issues while early in the design process. The results, to be shared with the space agency, will help to further understanding of the systems, standards and interfaces needed to make living in deep space possible.

This is nice, but it is essentially make-work for Lockheed Martin and a waste of money. At this stage of our engineering knowledge, we need to fly our interplanetary spaceship prototypes. Building them on the ground can only provide a limited amount of new knowledge, much of which has already been learned from numerous very similar past ground-based experiments.

For example, why isn’t NASA and Lockheed Martin also partnering with SpaceX, contracting to fly Donatello on the Falcon Heavy? That makes a lot more sense, and would not cost a lot of additional money. In fact, it might be quite cheap, since SpaceX needs customers willing to gamble on its new heavy-lift rocket.

Schedule for commercial manned flights solidifies

5:54 pm

Capitlism in space: It appears that the schedule for the first unmanned and manned test flights of the commercial capsules being built by SpaceX and Boeing is getting more certain.

The latest SpaceX schedule calls for an uncrewed test flight in February 2018, followed by a crewed test flight in June 2018. Boeing’s schedule anticipates an uncrewed test flight in June 2018 and a crewed test flight in August 2018.

While this sounds encouraging, the story contradicts a Boeing report last week that suggested their first manned flight would be delayed into the fourth quarter of 2018. Both stories however pin the first unmanned demo flight for June 2018, which now seems to be a firm date.

Opportunity enters Perseverance Valley

10:06 am

Opportunity in Perseverance Valley

Just prior to the drop in communications this week because of the Sun’s position between the Earth and Mars, Opportunity was ordered down into Perseverance Valley, where it will sit until the return of full communications.

Opportunity entered Perseverance Valley on the west rim of Endeavour crater. The rover is positioned within the valley where she will spend the solar conjunction period.

Solar conjunction is when the Sun comes between Earth and Mars, which occurs about once every 26 months. During this time, there will be diminished communications to Opportunity. More on solar conjunction here: https://mars.jpl.nasa.gov/allaboutmars/nightsky/solar-conjunction/

Two weeks of commanding have been uploaded to the rover to keep her active during solar conjunction with short communications with the Mars orbiters during the period.

The image on the right, reduced to show here, was taken by the rover’s navigation camera looking back uphill at the crater’s crest and the rover’s tracks in the valley. For the scientists the tracks are important because they reveal what the surface of the valley is like, which will help them determine whether it was formed from flowing water, flowing ice, or wind.

Even more significant, this initial drive into the valley means the science team has decided that either the wheel issues in June were not serious enough to prevent them from making this downhill trip, or the science is important enough that they are willing to risk the rover to get that science.

Growing cucumbers in space

9:48 am

New research growing cucumbers on ISS has found that the roots of these plants grew in the direction of water in weightlessness.

Plant roots grow to find water, according to a process known as hydrotropism. Roots are also influenced by gravity and tend to grow downwards, called gravitropism. To find out whether gravity or water had the greater influence on root growth, investigators grew cucumber plants in the microgravity environment on board the International Space Station. In their experiments, water (or hydrotropism) had more influence in controlling root growth.

“We will be able to utilize roots’ ability to sense moisture gradients for controlling root growth orientation and efficiently growing plants in future space farms,” said Dr. Hideyuki Takahashi, senior author of the New Phytologist study.

You can read the full science paper here.

This might sound obvious, but it isn’t. Past plant growth experiments on Mir and ISS had tended to show that plant roots did not know where to grow in weightlessness, suggesting that they needed gravity to guide the roots to water. Because of this, later experiments in space provided the roots complicated engineering to guide the roots to the water.

This experiment shows that maybe that complex engineering is not necessary, or at least could be simplified a bit. At a minimum it is crucial information engineers will need to design any future gardens for interplanetary spaceships with long term weightlessness.

ISRO’s 104 satellite launched earned India about $7 million

9:23 am

Capitalism in space: India’s space agency ISRO on Wednesday revealed to that country’s parliament that its record-setting 104 satellite launch on June 23 earned about $7 million.

On June 23 this year, PSLV-C38 had launched 712-kg Cartosat-2 satellite along with 30 co-passenger satellites. Of the 30 nano satellites, while one belonged to Noorul Islam University from Tamil Nadu, the rest 29 were from 14 foreign countries. On Wednesday, the government informed the Lok Sabha that the launch of 29 foreign satellites helped Antrix Corporation Ltd (ACL), the commercial and marketing arm of Isro, earn Rs 45 crore (6.1 million euros).

Before the June 23 multiple launch, Isro made the world record when its PSLV C37 launched 104 satellites in one go on February 15 this year. However, the space agency did not reveal how much it earned from that record-breaking launch. Out of the 104 satellites, 96 were from the US, three from India and one each from Israel, Kazakhstan, the Netherlands, Switzerland and the UAE.

From an American perspective it is encouraging that U.S. companies dominated the satellite count. From India’s perspective, the profits here are only going to encourage that nation to push for more rockets and cheaper costs.

The one problem I see with this is that it is the government that is obtaining the profits, not private Indian citizens or companies. Such an arrangement will not be good for India in the long run, as it encourages the government to use its coercive power to squelch private competitors.

Due to an accident during satellite launch preparations, NASA and Boeing are planning to replace a damaged antenna on NASA’s TDRS-M satellite, used by NASA mainly for communications between the ground and ISS.

The update at the link however says nothing whether the satellite will still launch on August 3, as presently scheduled. Nor have they released any information about the accident itself.

Opportunity takes panorama at top of Perseverance Valley

3:38 pm

On top of Perseverance Valley

During Opportunity’s two week pause in its travels in June as engineers tried to diagnose a problem with its left-front wheel, it took a wide panorama of the surrounding terrain, including the top of Perseverance Valley, released today.

The full panorama, shown above in reduced resolution, is a bit confusing. The head of Perseverance Valley to the northeast is on the right. The view straight ahead looks west, away from the crater. The hill and raising terrain on the left is the crater rim to the south of Perseverance Valley. The panorama is not a complete 360 degree view, as it does not include a direct view to the east and into Endeavour Crater itself.

Be sure and click on the link and look at the full image. The top of the valley is really interesting to view. Was it formed by wind or water or water ice? They hope to find out.
