Does this make you feel safer? China earlier this month tested a long-range missile capable of launching ten independently targeted warheads.
This missile is a larger variation of the mobile-launch DF-21 missile that is the basis for China’s commercial Kuaizhou rocket.
Link here. The report essentially confirms my own conclusions that I posted several weeks ago. This new report however also looks at total payloads, something I had not done, and finds that though there was a decline in 2016 in the number of satellites launched, they expect that trend to end in 2017 with the continued growth in the smallsat industry.
Because of the failure of the atomic clocks on one of its GPS satellites have failed, India now plans to launch one of their spare satellites to increase the system’s redundancy.
The article does not say whether they will make any changes to the clocks on the spare satellite, which are the same as the failed clocks on the Indian satellite and were all built by the same European company that built the clocks on Europe’s Galileo GPS satellites that are also failing.
An evening pause: I’m not sure if his concept for a different way to interact with the computer is really the best way to do it, but his willingness to try something new makes it all worthwhile. There will — and have been — payoffs.

Because the launchpad at Kennedy is not quite ready for the planned February 3 launch of a commercial satellite, SpaceX has rearranged its launch manifest to switch that launch with the next Dragon mission to ISS, essentially delaying their next launch by two weeks.
With [launchpad] 39A still not ready to debut in its new role with SpaceX, the first mission set to launch from this pad – the Falcon 9 launch with EchoStar 23 – was pushed to the right a number of times. Although 39A is very close to being ready to conduct launches, EchoStar 23’s launch date was deemed to be too close to the mid-February target for the CRS-10 Dragon mission.
SpaceX and NASA discussed the situation on Friday night, before deciding it would be prudent to place EchoStar 23’s launch after CRS-10, allowing engineers to finalize modification and checkout work on the famous pad and simultaneously avoid a potential delay to the important Dragon mission to the Station.
The real problem here is that SpaceX had planned to have two working launchpads by this time, but doesn’t because their first pad was damaged in the September 1 Falcon 9 launchpad explosion. The consequences is that, for at least the next month, they will not be able to set a pace of a launch every two weeks.
A Russian Soyuz rocket, built for Arianespace and launched from French Guiana, successfully placed a commercial satellite in geosynchronous orbit on Friday.
The launch has some significance. First, it was the first time a Soyuz rocket placed a payload into geosynchronous orbit. Second, the payload was the first satellite built by a German company in more than 25 years
Finally, and most important, it demonstrated that at least one configuration of the Soyuz rocket is still operational as Russia investigates the corrupt practices at the company that has been building upper stage engines for both its Soyuz and Proton rockets.
Update: Russia has revealed that this on-going investigation will now delay the next Proton rocket launch for 3.5 months. This means that launch will occur sometime in May, and will occur just weeks short of a full year after the last Proton launch on June 9, 2016.
Yesterday while I was sitting at my desk working on my Linux desktop computer, I got a phone call from someone from “Windows Technical Support.” The man on the line said to me, quite nicely, that they had noticed a problem with my computer and wanted to help me fix it.
I said, “You are talking about my Windows desktop computer, the one I am working right now, correct?”
The man said sweetly, “Yes, sir. That’s the computer we have seen a problem with.”
I answered sweetly, “I just want to be sure, so let me ask again. You are referring to the Windows computer in front of me, the one on my desk?”
He responded, “Yes sir. Could you press your start menu please and go to settings?”
Unfortunately, I had too much work to do, and couldn’t spend more time with him. I would have liked to have led him along for as long as possible, but simple didn’t have the time. Instead, I said, “Um, I can’t really go to my Windows settings because my desktop is a Linux computer, and has been for a decade. Have you heard of Linux?”
Instantly the phone went dead.
I tell this tale because it is only one more reason I abandoned Windows back in 2006. With Linux I have no viruses to worry about, and scammers like this can’t do me any harm.
Anyway, this post really isn’t about Windows scammers. Instead, I want to relate my experience this past week in setting up my first Linux laptop, following the step-by-step instructions provided by James Stephens and posted here on Behind the Black last year in the following series:

Scientists using a diamond vise think they have produced the first speck of solid metallic hydrogen, potentially capable of being a superconductor at normal temperatures.
While the scientists who performed the experiment believe they have succeeded, others are skeptical. Read it all. This is quite fascinating research.
The first preliminary results from NASA’s comparison of Scott Kelly, who spent 340 days on ISS, and his twin brother Mark, who did not, suggests that weightlessness stresses the body’s genetic system in ways not previously measured.
Preliminary results are in from NASA’s unprecedented twin study — a detailed probe of the genetic differences between astronaut Scott Kelly, who spent nearly a consecutive year in space, and his identical twin Mark. Measurements taken before, during and after Scott Kelly’s mission reveal changes in gene expression, DNA methylation and other biological markers that are likely attributable to his time in orbit.
From the lengths of the twins’ chromosomes to the microbiomes in their guts, “almost everyone is reporting that we see differences”, says Christopher Mason, a geneticist at Weill Cornell Medical College in New York City. He and other project scientists reported the early results on 26 January in Galveston, Texas, at a meeting of scientists working in NASA’s Human Research Program. “The data are so fresh that some of them are still coming off the sequencing machines,” Mason says.
It remains unclear at this point the medical consequences of these genetic changes. The data from this first experiment is still too preliminary, and it only involves looking at two people, a sample that is obviously too small. Nonetheless, it is a beginning, and of some significance.

Fifty years ago Friday, the first – but sadly not the last – fatal spaceflight accident struck NASA when a fire claimed the lives of Virgil “Gus” Grissom, Roger Chaffee, and Ed White during a training exercise at Launch Complex 34. The accident, a major setback for the struggling Apollo program, ushered in the first understanding of the “bad day” effects of schedule pressure for spaceflight and brought with it words and reminders that still echo today.
The article provides a very detailed and accurate look at the history and causes of the accident, as well as its consequences, which even today influence American space engineering.
The competition heats up: Sierra Nevada’s Dream Chaser test vehicle has arrived at Edwards Air Force Base for several months of tests, including at least one drop test.
They are presently aiming for a first cargo flight to ISS in 2019.
Cool image time! The image on the right, cropped to show here, is focused in on Jupiter’s Little Red Spot, a storm that formed by the merger of three smaller storms about a decade ago. The cropped image comes from a wider view of Jupiter from Juno that is quite amazing.
Note that the Little Red Spot, while only a third the size the more well known Giant Red Spot, is still about the size of the Earth.
This storm is the third largest anticyclonic reddish oval on the planet, which Earth-based observers have tracked for the last 23 years. An anticyclone is a weather phenomenon with large-scale circulation of winds around a central region of high atmospheric pressure. They rotate clockwise in the northern hemisphere, and counterclockwise in the southern hemisphere. The Little Red Spot shows very little color, just a pale brown smudge in the center. The color is very similar to the surroundings, making it difficult to see as it blends in with the clouds nearby. Citizen scientists Gerald Eichstaedt and John Rogers processed the image and drafted the caption.
The competition heats up: India successfully completed today a 50-second static fire test of the upper stage engine for its GSLV rocket.
The rocket’s next launch is set for March.
The first Mars mission by the United Arab Emirates, dubbed Hope, is still be on schedule for its 2020 launch, according to the mission’s project manager.
Omran Sharaf said: “The mission has been on track so far. We’ve completed the PDR — Preliminary Design Review — and hopefully we’ll hold the CDR [Critical Design Review] soon.” His comments came during his presentation on ‘How Could the UAE Get to Mars?’ on the second and final day of the [Project Space] forum, held at Dubai World Trade Centre for the first time. Project Space is held under the patronage of Shaikh Hamdan Bin Mohammad Bin Rashid Al Maktoum, Crown Prince of Dubai. Shaikh Hamdan is the chairman of the Mohammad Bin Rashid Space Centre (MBRSC), organiser of Project Space.
During Wednesday’s talk on EMM, Sharaf added that “the system design has been completed … and we’re starting to work on the engineering models of the mission. So this is the current phase of the mission”.
Like most stories about space coming from the UAE, they spend more time listing the titles of the bigwigs running the project than providing much specific information about the project itself. I remain skeptical they can pull this off.
One of India’s seven GPS satellites is presently out of commission because its on-board atomic clock has malfunctioned.
The remaining satellites in the constellation is still functioning however, and are sufficient. The nature of this failure, so similar to the clock failures that have hit a number of Europe’s Galileo GPS satellites, makes me wonder if there is a connection.
The competition heats up: Boeing today unveiled the streamlined but snazzy spacesuit it plans to use on its Starliner manned ferry flights to and from ISS.
This tidbit though I think illustrates the new mindset, to make things simpler and cheaper and more focused on their actual purpose.
Boeing’s suit, designed with the Massachusetts-based David Clark Co., weighs about 12 pounds, compared to 30 pounds for NASA’s orange suits formally called the Advanced Crew Escape Suit, or ACES. …The “get us home suit,” as Ferguson called it, couldn’t be used for a spacewalk. It’s intended to provide air and cooling to keep astronauts safe during launch and landings back on land, and during emergencies, like if a micrometeoroid strike caused a loss of cabin pressure.
Cool image time! The image above, taken on January 16, 2017 during one of Cassini’s ring-grazing passes as it enters its last year at Saturn, has been reduced and cropped to post here. It shows clearly the waves caused by the gravity of the moon Daphnis as its travels within a gap in the rings of Saturn.
Daphnis (5 miles or 8 kilometers across) orbits within the 42-kilometer (26-mile) wide Keeler Gap. Cassini’s viewing angle causes the gap to appear narrower than it actually is, due to foreshorteneing. The little moon’s gravity raises waves in the edges of the gap in both the horizontal and vertical directions.
The image also shows many details about Daphnis itself, including a ridge at its equator that is thought to be an accumulation of material gathered from the rings.
The strangeness of Saturn’s rings is well illustrated here. Though made up of many solid particles, as a group the rings act almost like liquid. Note for example the ring on the far side of Daphnis. Its edge gets pulled out slightly as the moon goes by, but then the gravity of the rest of the ring pulls it back.
The universe is a wonderful place, as it is. No need to make up stuff (such as faces on Mars or fake civilizations on the Moon), as our imagination is probably insufficient to match the weirdness that is really out there.
The competition heats up: The five finalists for the Google Lunar X-Prize have now been set.
Five teams remain in the running: Israel’s SpaceIL, Florida-based Moon Express, an international team known as Synergy Moon, India’s Team Indus and Japan’s Hakuto.
SpaceIL plans to fly on a SpaceX Falcon 9 rocket, which recently returned to flight following a launch pad accident. Team Indus and Hakuto will share a ride on an Indian PSLV launcher. Moon Express is banking on a launch from startup Rocket Lab, which is developing a small rocket called Electron. Whether it wins the XPrize or not, Moon Express is building a business to provide lunar transportation and services, such as research and mineral extraction, Chief Executive Bob Richards said in an interview. Synergy Moon is counting on one of its partners, Mojave, Calif.-based Interorbital Systems, for its launch aboard a new rocket known as Neptune.
To win, one of these teams must fly its mission before the end of 2017.
Confirmed: As a result of its investigation into the problems during a June 9, 2016 launch, Roscosmos has now grounded its Proton rocket for at least the next six months due to the discovery of systemic quality control problems throughout the entire Proton construction process.
On January 23, the Kazakh-based division of the Interfax news agency reported the likelihood of an unusually lengthy delay with Proton missions, which could last several months. A day later, the Kommersant newspaper reported that a recent firing test had revealed technical problems with RD-0210 and RD-0212 engines, which propel the second and third stage of the Proton rocket respectively. The failure of the engine was reportedly traced to illegal replacement of precious heat-resistant alloys within the engine’s components with less expensive but failure-prone materials. The report in the Kommersant echoed the results of the investigation into the 2015 Proton failure, which found that low-quality material in the turbo-pump shaft of the engine had led to the accident.
On Jan. 20, 2017, Head of Roskosmos Igor Komarov chaired a meeting of the top managers at the Voronezh Mechanical Plant, VMZ, which manufactures rocket engines, including those used on the third stage of the Soyuz rocket and on the second and third stages of Proton. The high-profile meeting followed a decision to return already manufactured RD-0110 engines from Soyuz rockets back to Voronezh, after such an engine had been suspected as the culprit in the loss of the Progress MS-04 cargo ship on Dec. 1, 2016, as it ascended to orbit onboard a Soyuz-U rocket. [emphasis mine]
The worst part of this story, from an American perspective, is that it might result in a complete grounding of Russia’s entire rocket fleet, since some of these issues involve the Soyuz rocket as well. All manned flights to ISS will stop, which might force us to abandon it for a time.
Read the article. It suggests that Russia’s space industry is now in big big trouble.
Update: The Russians are replacing the entire Soyuz capsule that they had planned to use for the March manned mission to ISS.
“Spaceship No. 734 may be replaced by spacecraft No. 735 over a leak in the descent module [of the 734th space vehicle]. This is not yet known for sure. The spacecraft will be returned for a check,” the source said.
The competition heats up: Japan today successfully launched its first military satellite.
Faced with an increased military challenge from China, even as the U.S. is becoming less willing to provide it military support, Japan has upped its military program significantly. This success is especially welcome, considering the string of engineering failures that Japan has experienced recently.
The Tuesday launch marks the successful resumption of a programme that was halted last year by an embarrassing mishap. The first of the three satellites, which was meant to go into space from Europe’s Space port in French Guiana, was crushed during a flight from Japan after a blue tarpaulin covering its transport box blocked valves meant to equalize the internal air pressure as the cargo aircraft descended. The accident damaged sensitive antennas, government sources told Reuters in July.
