India hopes to resume launches before December

Despite an August 31 launch failure, India is still planning to resume launches before December.

On Friday, Mr Kiran Kumar [head of ISRO] was optimistic that the workhorse rocket would resume flights within a couple of months. “We have identified what the problem is, and we are going through simulations to make sure what we are concluding, is what has exactly happened (during the unsuccessful flight on August 31). The committee, which has been set up to go through the report is having detailed discussions and the report will come out very soon. After the committee gives its final report, we will resume the launches by November-December,” he said, on the sidelines of silver jubilee celebrations of Antrix Corporation Ltd, the corporate arm of ISRO.

They might not meet this goal, but that they are trying to resume launches in less than four months indicates that they are emulating the private sector and not most typical government agencies like NASA in this matter. Both NASA and ISRO have in the past sometimes taken years to recover from a launch failure. After SpaceX’s launchpad explosion in September 2016 they vowed to launch in less than four months, and managed to do it in five months. That ISRO is now trying to do the same indicates that the competition has forced them to up their game.

The Worst Part of Losing Cassini Is That It Has No Replacement

Link here. This article is an honest review of the current lack of concrete plans by anyone to send a new probe to Saturn. While there are some tentative missions in the works, nothing is certain.

[I]f looking back on Cassini’s major discoveries at Saturn, Titan, and Enceladus have left you thirsty for more, we have some bad news: That thirst is going to go unquenched for a while. Talks of Uranus and Neptune missions are tentative at best. The best hope for Saturn now comes from NASA’s New Frontiers program, which looks for excellent medium-cost missions has spawned spacecraft including Jupiter’s Juno and Pluto’s New Horizons. This round of New Frontiers missions must launch by 2024, and there are two Enceladus proposals, a Titan proposal, and a Saturn atmospheric probe under consideration. We may hear word about those proposals by the end of the year “Hang tight, we’re going through the evaluations now and we’ll be announcing at the end of the year what some of the finalists will be,” Jim Green, NASA Planetary Science Director, said at the Cassini press conference Friday morning.

This list of possible Saturn missions sounds great, but they are all competing against each other and a number of other equally (and possibly more) interesting missions to other places. And with the federal budget out of control and mired in debt, there isn’t really a lot of money to go around.

3D image of Jupiter

Another citizen scientist who goes by the moniker of mesno has uploaded a spectacular 3D anaglyph of one of Juno’s images of Jupiter.

I could post it here, but I’d have to reduce its resolution, and I don’t think this will work well. If you have red-blue anaglyph 3D glasses the image does a great job of showing the differing vertical heights of Jupiter’s many horizontal bands, especially since it exaggerates the vertical scale significantly to bring out these differences.

Mesno has done three other anaglyphs. Check them out. The image of the Great Red Spot really shows how this is a vast whirlpool boring deep into Jupiter’s atmosphere.

Orbital ATK begins assembly of first orbital repair satellite

Capitalism in space: Orbital ATK has begun the assembly of Mission Extension Vehicle 1, (MEV-1), designed to attach itself to commercial satellites and extend their life.

Controlled by the company’s satellite operations team, the MEV 1 uses a reliable, low-risk docking system that attaches to existing features on a customer’s satellite. The MEV-1 provides life-extending services by taking over the orbit maintenance and attitude control functions of the client’s spacecraft. The vehicle has a 15 year design life with the ability to perform numerous dockings and repositionings during its life span.

They hope to launch before the end of 2018. Meanwhile, the legal battle between Orbital ATK’s effort to build this satellite repair mission and DARPA’s effort to subsidize SSL’s own satellite repair mission continues in Congress with the introduction of two amendments favoring Orbital ATK.

Cassini’s mission ends

Enceladus as seen by Cassini two days before mission end

After a seven year journey and thirteen years in orbit around Saturn, Cassini’s mission ended early this morning with a dive into Saturn’s atmosphere.

The image above, cropped to show here, is actually one from a short movie, showing Enceladus setting behind the horizon of Saturn. The images were taking two days ago, but provide a fitting image for the mission’s end.

Some of the best images from the dive, including Cassini’s last image, can be found here.

While most of the press will rightly wax eloquent about the magnificence of this mission, my focus remains on what will come next. We no longer have any way to observe what is happening on Saturn. We are blind. We should not be.

ESA buys the first Ariane 6 launches

The European Space Agency (ESA) has purchased the first two Ariane 6 launches to place four of its Galileo GPS satellites in orbit in the 2020-21 timeframe.

This is not a big surprise, since ESA is mandated to use Arianespace’s rockets, and the space agency is the obvious candidate for making the first commitment to this new rocket’s use.

The press release does not mention the price that Arianespace is charging for these launches, but I suspect it isn’t anywhere near as cheap as they will have to charge to truly private and commercial customers. Essentially, I am willing to bet that this contract award is a bit of crony capitalism, designed to pass some extra cash from ESA to Arianespace.

How not to land a rocket

The SpaceX blooper reel! It shows some crash footage that had not been released earlier. Also, the captions almost certainly were written by Musk himself, and if not, reek of his sense of humor, and also reveal the humbleness that he and his company bring to this effort. If you can’t laugh at yourself, you will make it hard to spot the moment when you are making a major error.

First global map of the trace water on the Moon

Trace water on moon

Using data collected by an American instrument on India’s Chandrayaan-1 lunar orbiter scientists have produced the first global map showing the locations and quantities of trace water on the Moon.

The map above, reduced to post here, is the result. The green areas at high latitudes show the most evidence of water, but the amounts remain very tiny, and the evidence remains somewhat uncertain.

Regardless, this map indicates that the high latitudes of the Moon will likely be the most valuable real estate for future colonists.

Cassini on final approach to Saturn

Engineers have confirmed that Cassini is now on its final approach to Saturn, with a scheduled dive into the gas giant set for Friday, September 15.

The mission’s final calculations predict loss of contact with the Cassini spacecraft will take place on Sept. 15 at 7:55 a.m. EDT (4:55 a.m. PDT). Cassini will enter Saturn’s atmosphere approximately one minute earlier, at an altitude of about 1,190 miles (1,915 kilometers) above the planet’s estimated cloud tops (the altitude where the air pressure is 1-bar, equivalent to sea level on Earth). During its dive into the atmosphere, the spacecraft’s speed will be approximately 70,000 miles (113,000 kilometers) per hour. The final plunge will take place on the day side of Saturn, near local noon, with the spacecraft entering the atmosphere around 10 degrees north latitude.

We will get Cassini’s last images about 90 minutes after its death.

An oral history of the Cassini mission to Saturn

Link here. Those who have read my book on the building of the Hubble Space Telescope will recognize many of the same people and political maneuvers used to get the project off the ground and funded.

Note too that the idea of Cassini was first proposed in 1982, but it didn’t actually launch until 1997. Fifteen years. While today I think such a spacecraft could go from concept to launch much faster, this timeline gives us a guide on when the next Saturn orbiter might launch. At the earliest do not expect another mission to Saturn to launch before 2025.

Virgin Orbit wins launch contract

Capitalism in space: Virgin Orbit today announced it has signed a contract with Cloud Constellation to launch the first dozen satellites in their SpaceBelt constellation.

The initial deployment of the SpaceBelt network will be powered by a dozen ~400 kilogram satellites placed into low inclination orbits. Taking full advantage of LauncherOne as a dedicated launch service for small satellites and as a uniquely flexible service enabled by air-launch, the SpaceBelt constellation will be deployed using single-manifested launches occurring in rapid sequence. The initial launch is expected to occur as early as 2019.

This definitely puts pressure on Virgin Orbit to produce its first launches as promised.

Space hype versus reality

Three stories today illustrate the importance of maintaining some skepticism when reading the claims of rocket companies.

I could probably also include the story earlier today about the model rocket test launch that was hyped absurdly by the company and the British newspapers that reported it.

The first story reports the comments of a local politician claiming that SpaceX will be launching from its Boca Chica Texas spaceport by the end of 2018. Interesting, but I’d rather go by what the company itself says, and what SpaceX CEO Gwynne Shotwell says today is “Our Texas site still doing landscaping, could be avail in ~ 2 yrs; no rush given our capacity at two Fla pads.”

In other words, the local official’s prediction was a bit overstated, and therefore should not be taken too seriously.

The second story however can be taken a bit more seriously, since it is a report from an actual company official, Clay Mowry, Blue Origin’s vice president of sales, marketing and customer experience. He explains that they hope to resume New Shepard suborbital test flights before the end of the year, with manned test flights occurring in 2018. However, he says little about why there was such a long gap in New Shepard launches after they completed their last test flight in October 2016. At that time they said they would be doing more test flights in early 2017, but by the spring of 2017 had back tracked.

The claim that they might be flying again before the end of the year, however, still carries weight, in that it matches earlier statements. In other words, Blue Origin has been very careful not to make promises it cannot meet. In rocket science this care cannot always be met, but they clearly have tried hard. This is why I take Mowry’s statement that they hope to fly humans on New Shepard in 2018 with some trust.

The third story is a perfect example of how a company loses trust. Virgin Orbit is part of the Virgin set of companies run by Richard Branson, and used to be part of Virgin Galactic. Branson and Virgin Galactic have been making promises now for more than a decade, none of which have born fruit. This unreliability has made me very skeptical about anything they say, which is also why I do not report their claims much anymore. When they actually fly something I will write about it.

For awhile I thought Virgin Orbit was a different bird, as the executives there have been more careful, only making cautious promises and then more or less fulfilling them. The story above however gives me pause. Even as they admit they have had to delay their test program their president still insists that they will be able to ramp up to two launches per month by 2020. Considering the fact that no single private company has yet managed to do such a thing, in the more than half century since the beginnings of the space age, I think it is a little dangerous for this guy to make this claim, even before the company has even launched its first rocket. Virgin Orbit might do it, but such wild claims make me very suspicious of them.

And then there was today’s earlier story about Starchaser Industries. They launch a model rocket 4000 feet in the air, and from this they claim that they will be putting humans on a suborbital rocket in only two years. If you believe that, I have a bridge in Brooklyn I can sell you, cheap.

The bottom line here is to use some common sense and thoughtful judgment in reading stories about future space achievements. The first three stories above are actually all well written, well researched, and very careful in how they report their stories. It however is not necessarily their job to tell you whether the claims are trustworthy, especially if the claims seem reasonable based upon the available information. The last however is an example of bad journalism, rewriting a press release without doing any research at all.

In all cases, it is important to distinguish between stories about what is going to happen versus what is happening. I always prefer the latter, since a real achievement will always trump a mere prediction. And when it comes to the space industry and rocket science, predictions surely must take a back seat to reality.

China successfully completes third robotic docking

China’s Tianzhou-1 test cargo freighter successfully completed its third docking with the prototype test space station module Tiangong-2 today.

Commands for the rendezvous and docking were issued at 17:24 Beijing time, according to the China Manned Space Agency, with the new ‘fast’ process taking 6.5 hours to complete.

Previously the rendezvous and docking process took around two days, or 30 orbits. The breakthrough will be used to allow crewed Shenzhou craft to reach the future Chinese Space Station (CSS) much sooner after launch.

Tianzhou-1 will soon perform a third and final refuelling test with Tiangong-2, before the cargo spacecraft is carefully deorbited over the South Pacific.

No word yet on when China might resume launches however. Since the July launch failure of their largest rocket, Long March 5, the country has launched nothing. There have also been stories that suggest the planned December launch of their Chang’e 5 lunar mission will be delayed now until the spring.

Movie of Juno’s September 1 fly-by of Jupiter

Citizen scientist Gerald Eichstädt has done it again, assembling and enhancing the images taken by Juno in its September 1, 2017 fly-by of Jupiter to produce a spectacular movie, embedded below.

In his words,

This animation reconstructs the two and a half hours from 2017-09-01T20:45:00 to 2017-09-01T23:15:00 in 125-fold time-lapse with 25 frames per second, using 20 raw JunoCam images. JunoCam is Juno’s optical and near infrared Education and Public Outreach camera.

Trajectory data are retrieved from SPICE kernels via the NAIF spy.exe tool. The NAIF/SPICE environment is the way NASA provides spacecraft navigation data.

The movie shows Jupiter in a heavily enhanced way, in order to reveal detail.

Some of the raw images cover only part of the area required to render a still of the movie. In these cases, you’ll see the border of the raw image.

Each image is rendered into a short scene. The scences overlap and are blended.

Rendering the movie took about five days. Any shortcomings of the movie are a result of imperfect image processing.

Curiosity tops Vera Rubin Ridge

Curiosity's view from on top of Vera Rubin Ridge, sol 1812

The image above is a reduced resolution version of a panorama created by reader Phil Veerkamp of images downloaded today from Curiosity. If you click on the image you can see the full resolution image. It looks to more to the east than the panorama shown in my September 6 rover update, revealing more of the type of surface the rover will have to cross on its drive forward on this new geological layer called the Hematite Unit.

Curiosity has now topped Vera Rubin Ridge, but the plateau above is really not as flat as the image implies. The Hematite Unit that the rover is now traversing still climbs upward, and they will continue to gain altitude now with almost every drive.

Arianespace announces new launch contracts

Capitalism in space: Arianespace today announced it has won a new launch contract for two different satellites, bringing its launch manifest to 53.

The press release contains a lot of interesting tidbits:

  • They plan to complete 11 launches in 2017, which is slightly above their yearly average in the past six years.
  • In 2018 they presently have only 7 launches planned, the lowest number since 2013.
  • Of the 53 launches, Ariane 5 will do 17, Soyuz 27, and Vega 9, suggesting a shift away from Ariane 5, which has been the company’s mainstay.
  • The private joint partnership of Airbus and Safran, now called ArianeGroup, has taken control of the business, and has begun streamlining it.
  • Arianespace has now been relegated to only handling “customer relations” and launch operations.

Overall, it looks like this European private/government partnership is doing reasonably well in the new very competitive launch market. I still expect their business to shrink in the coming years, but I think they will be around for awhile.

Private rocket does short test flight

Capitalism in space: A private British rocket company, Starchaser Industries, successfully launched a small rocket from the back of a truck yesterday and sent it about 4,000 feet in the air.

All the articles covering this event appeared to essentially be rewrites of the company’s press release, and provide little usable information about the flight. The test launch had the rocket split into three sections at 4,000 feet and return to Earth by parachute. This apparently was the intended test goal, though one parachute did not release.

Based on what I read, I must admit I am not impressed. The head of the company made a lot of claims about flying humans on a bigger rocket soon to come, but based on this launch I think that is almost all hogwash. Essentially this launch looked like a big model rocket, with little capabilities beyond that. Previous stories about this company and its head have been equally dubious. In one, he made ridiculous claims. In another, it was reported that his bookkeeper had embezzled 200K pounds over six years from the company.

All in all, I think my real issue here is with the press. I read five different stories about this launch from so-called major British news sources like the Times of London and the Daily Telegraph, and not one had the slightest skepticism, or did the slightest research. Each journalist also appeared completely ignorant of space engineering and the history of space exploration, and seemed more interested in touting the wonders to come from this British entrepreneur. As a journalist myself I found this incredibly embarrassing.

New Horizons team looks for second flyby in Kuiper Belt

The New Horizons science team is hoping to send their probe past a second more distant Kuiper Belt object after its January 1, 2019 flyby of 2014 MU69, if they can find an object that the spacecraft can reach.

They haven’t found any candidates yet, NASA has not agreed to a mission extension anyway, and their focus now remains the 2019 flyby. Still, if they are lucky and can get another target, this would be a nice bonus for the mission.

Russia’s Proton rocket today successfully launched a commercial satellite

The competition heats up: Russia today successfully placed a Spanish communications satellite into orbit using its Proton rocket.

Russia remains one launch behind SpaceX, 13 to 12, for 2017, but they have three more launches scheduled for September, while SpaceX has nothing planned. Overall I think it is going to be a neck and neck race between the American private company and Russia, the former perennial leader in launches, for the final 2017 lead.

Cassini says goodbye to Saturn

Saturn, October 2016

Cool image time! The picture above, reduced in resolution to show here, was taken in October 2016 during one of Cassini’s last distant orbits that gave it a global view of Saturn and its rings. Since it began its dives close to the gas giant such views have not been possible.

The mission ends this coming Saturday with a dive into Saturn. It was launched in October 1997, and after a seven year journey has spent the last thirteen years in orbit around the planet, providing us the first long term glimpse of a gas giant as its seasons evolved.

Cassini has been orbiting Saturn for nearly a half of a Saturnian year but that journey is nearing its end. This extended stay has permitted observations of the long-term variability of the planet, moons, rings, and magnetosphere, observations not possible from short, fly-by style missions.

When the spacecraft arrived at Saturn in 2004, the planet’s northern hemisphere, seen here at top, was in darkness, just beginning to emerge from winter (see Cassini’s Holiday Greetings​). Now at journey’s end, the entire north pole is bathed in the continuous sunlight of summer.

The spacecraft was also able to observe the seasonal changes that occurred to Titan. It also studied the plumes coming from the tiger stripe cracks on Enceladus, shown below the fold in a movie created by Cassini over a 14 hour time period in August 2017.

I expect that scientists will be exploring Cassini’s data archive for decades, finding many things not noticed in their initial viewing. Unfortunately, we will not have another spacecraft taking new pictures in orbit around Saturn to compare with Cassini’s past images for many decades to come. On Saturday, we go blind.

Why is no one buying time on Nigeria’s satellites?

Despite having four working communications and Earth observation satellites in orbit, Nigeria officials complain there is a lack of interest in using them by both private companies and international governments.

The reasons? Well, two Nigerian officials said this:

[The Director, Centre for Satellite Technology Development (CSTD), Dr Spencer Onuh, told Daily Trust in an exclusive interview. “What do you want them to do when there is a failure? Let me tell you, NigComSat 1R is not enough for this country; it is not sufficient. There must be a backup. Many TV stations and even the national TV network will be very careful to transfer their services fully to NigComSat 1R because it is just one. The stations are set up for business, and they would not want anything to disrupt their services,” Dr Onu said.

He said it was not an issue of redundancy, adding that there was a need for market expansion…. He said: “Even private companies that own satellites don’t have only one. Some of them have five to six satellites, but mostly communication satellites which spin money. The return on investment is very fast but what happens in most advanced satellite countries is that these things are given out to the private sector to manage; they are not under government management and you can see the results.”

But a NIGCOMSAT official, Abdulraheem Isah Adajah, disagreed. Adajah who is the NIGCOMSAT’s General Manager, Satellite Applications, told Daily Trust that it was not entirely true that Nigcomsat1-R was recording low patronage due to lack of backup. According to him, inferiority complex and the mentality that ‘if it is Nigerian it can’t be good’ is the main reason. He called on the Federal Executive Council to come up with a policy which would make it compulsory for government agencies to patronise Nigeria’s satellites. [emphasis mine]

Typical thinking from government types. One government official lobbies for the government to build more satellites, while the other says the law should require their use. Neither seems very interested in discussing the actual lack of market demand that might be making these satellites unprofitable.

The article quotes a number of other government officials, most of whom remind me of the two above. Only one hints at the major source of the problem (the government), by noting that bickering between different Nigerian government agencies has been a factor. For example, the government agency that provides satellite television to Nigeria no longer buys time on these satellites, claiming that they have no backup should something go wrong.

It is a good thing that Nigeria is doing this. The problem is that it is their government doing it, instead of a private industry looking for profit.

ULA delays California launch because of Florida hurricane

Because some of its employees needed for a California launch in next week live in Florida, ULA has decided to delay that launch so that those employees can focus on preparing for and recovering from Hurricane Irma in Florida.

What I find interesting about this story is that it reveals that ULA, unlike SpaceX, apparently does not have more than one launch team, even though their staffing has historically been much higher. This limits their ability to do frequent launches, as well as launches from both coasts.

Saturn’s magnificent rings

Saturn's rings

The Cassini science team released two sets of images taken by the spacecraft of Saturn’s rings.

The image above, reduced in resolution to show here, is from the second link. As they note,

The pale tan color is generally not perceptible with the naked eye in telescope views, especially given that Saturn has a similar hue.

The material responsible for bestowing this color on the rings—which are mostly water ice and would otherwise appear white—is a matter of intense debate among ring scientists that will hopefully be settled by new in-situ observations before the end of Cassini’s mission.

The different ringlets seen here are part of what is called the “irregular structure” of the B ring. Cassini radio occultations of the rings have shown that these features have extremely sharp boundaries on even smaller scales (radially, or along the direction outward from Saturn) than the camera can resolve here. Closer to Saturn, the irregular structures become fuzzier and more rounded, less opaque, and their color contrast diminishes.

Check out both. They reveal to me that our understanding of these rings remains essentially nil, even after more than a dozen years of study by Cassini.

First Juno movie of Jupiter’s changing weather

Gerald Eichstädt at the Juno image site has produced the first attempt to assemble a movie of Juno images of the same area on Jupiter in order to show its changing weather.

JunoCam has been seeing this scene about six times from very different perspectives between about 2017-09-01T22:03 and about 2017-09-01T22:19, hence a over a little more than 15 minutes.

This animation is a first attempt to reproject the six images to a similar common perspective in order to reveal some dynamical information.

An movie covering only 15 minutes won’t show much change, but it is a start. He also notes that in making the different images match up he likely introduced some artifacts that are not real.

Plan of New Horizons’ fly-by of 2014 MU69 announced

The New Horizons science team has announced its detailed plan for the January 1, 2019 fly-by of Kuiper Belt object 2014 MU69.

If all goes as planned, New Horizons will come to within just 2,175 miles (3,500 kilometers) of MU69 at closest approach, peering down on it from celestial north. The alternate plan, to be employed in certain contingency situations such as the discovery of debris near MU69, would take New Horizons within 6,000 miles (10,000 kilometers) — still closer than the 7,800-mile (12,500-kilometer) flyby distance to Pluto.

…If the closer approach is executed, the highest-resolution camera on New Horizons, the telescopic Long Range Reconnaissance Imager (LORRI) should be able to spot details as small as 230 feet (70 meters) across, for example, compared to nearly 600 feet (183 meters) on Pluto.

MU69 is thought to either be two objects orbiting very close to each other or an object similar to Comet 67P/C-G, two objects in contact but barely so.

In a related New Horizons story, the International Astronautical Union (IAU) has officially accepted 14 names chosen by the New Horizons team for features on Pluto.

Juno finds mystery in Jupiter’s aurora

The uncertainty of science: Scientists analyzing the data sent back by Juno have found that the system for generating Jupiter’s aurora does not appear to be same as the process that creates auroras on Earth.

The science here is a bit complicated. Suffice it to say that Jupiter’s aurora seems produced by a much more complex process, which actually should not have surprised anyone, considering how much larger Jupiter is and more powerful its magnetic field.
