It’s now been several months since China admitted that it had completely lost control of its Tiangong-1 space station, explaining that without the ability to adjust its position in orbit the huge manmade object will eventually come falling back down to Earth. In late 2017 the Chinese government offered a very rough forecast of when the satellite could collide with our planet, and now it’s looking more and more like March might be the month when it happens.
According to the latest information from the European Space Agency,the space station is now expected to come tumbling down somewhere between March 24th and April 19th. ESA says it’s more likely that the object will land somewhere in the northern latitudes, meaning the northern US, parts of Spain, Portugal, Greece, China, much of the Middle East, and a handful of other countries.
The space station, whose name means “Heavenly Palace,” will be subjected to the full brunt of friction from Earth’s atmosphere and, thankfully, will be incinerated almost completely before any remaining debris finally lands on the surface. However, it’s still possible that the spacecraft could cause some problems if it lands on hard ground, especially in a populated area.
Some of the material on board the space station is indeed toxic, including chemicals used in rocket fuel, and China has noted that if that material finds its way to the ground it could be hazardous to anyone who stumbles upon it.
That being said, the odds of any debris actually landing near you or, even worse, striking you is incredibly small. Space debris experts put the chances of being struck by space debris at around a million times less likely than winning the lottery.
In any case, the ESA and other space agencies will be keeping a close eye on the space station and will hopefully be able to forecast its fall from the sky with greater accuracy as the day draws near.

The U.S. Air Force wants 22 new GPS satellites that are built to resist jamming and electronic interference. It would spend around $2 billion on the new satellites for the GPS 3 constellation in the next five years. The production of all 22 satellites is expected to be worth as much as $10 billion
“The GPS 3 that we are moving toward is more jam-resistant, and it is intended to be able to operate in a contested environment,” Secretary of the Air Force Heather Wilson said.
The constellation of 31 GPS 2 satellites currently in orbit will remain operational until at least 2021. The Air Force has already ordered 10 GPS 3 satellites from Lockheed Martin. But, the Air Force has now decided it needs to quit buying up those GPS 3 satellites and go back to the drawing board.
Lockheed Martin will most likely bid for the contract to build the new jam-resistant satellites, but other contractors like Boeing and Northrop Grumman are expected to try as well. Development of the new satellites would take place in 2019.
Did you read the recent story about JPL “dressmaker” Lien Pham who makes thermal blankets for spacecraft? The materials, methods, and techniques are an amazing combination of traditional and very techy.
“What kind of materials go into a thermal blanket?
We use multiple layers of Mylar films with Dacron netting to separate them. For the outermost surface, we use Kapton film or Beta cloth, which resist temperature change.
We also use gold Kapton, which is good for conducting electricity. There’s a black material called carbon field Kapton. That’s for a charged environment, with a lot of electricity. It dissipates the charge.
What Kind of tools do you use?
We use commercial sewing machines designed for thick material such as denim. It has a walking feed that pulls in the material and cuts our sewing thread automatically. We also use a variety of hand tools like a measuring scale, scissors, surgical scalpels, hole punches, a heat gun, leather punch and weight scale.”
A BBC.com article on Lian Pham and the JPL seamstresses explains
“Nasa hires women with sewing experience for a reason. When engineers couldn’t figure out how to work with Teflon – the non-stick material that coats many saucepans – they were at a loss.
Lien suggested folding the edge of the material and sewing it like a hem, as she would with a shirt at home.
“The derived composition and profile suggest that WASP-18b is the first example of both a planet with a non-oxide driven thermal inversion and a planet with an atmospheric metallicity inconsistent with that predicted for Jupiter-mass planets.”

Please send other fun links showing Navy humor to email@example.com. We will post them on the website. They do not have to relate to the Army-Navy game.
Several of ATI’s instructors have graduated from or taught at the Navy Academy, so it is obvious that we will root for the USNA.
We also have 2 son-in-laws actively serving in the Navy surface warfare fleet, so it is obvious that we will be biased for the USNA. We will try to be somewhat fair, as our third son-in-law is a retired Army EOD specialist, who is still in the active reserve.
There’s a small, icy object floating at the outer edge of our Solar System, in the messy Kuiper belt. Or it could be two objects, astronomers are not sure.
But NASA is on track to find out more, as that object has been chosen as the next flyby target for the New Horizons spacecraft – the same probe that gave us incredible photos of Pluto in 2015. And now they want your help to give that target a catchy name.
Currently, the enigmatic Kuiper belt object is designated 2014 MU69, but that’s just the provisional string of letters and numbers any newly discovered object gets.
“Yes, we’re going to give 2014 MU69 a real name, rather than just the “license plate” designator it has now,” New Horizons’ principal investigator Alan Stern wrote in a blog post earlier this year.
“The details of how we’ll name it are still being worked out, but NASA announced a few weeks back that it will involve a public naming contest.”
And now, folks, our time to shine has arrived.
NASA has finally extended an invitation for people to submit their ideas for a name, although they note this is not going to be the officially-official name just yet, but rather a nickname to be used until the flyby happens.
The team at New Horizons already have a bunch of ideas prepared, which now form the basis of the naming campaign, and anyone can already vote for those.
Amongst current choices put forward by the team are Z’ha’dum – a fictional planet from the TV series Babylon 5; Camalor – a fictional city actually located in the Kuiper belt according to Robert L. Forward’s novel Camelot 30K; and Mjölnir – the name of Norse thunder god Thor’s epic hammer.
One of the most interesting aspects of MU69 is that we’re not even sure whether the object is one body or two – telescope observations have hinted it could actually be two similarly-sized bodies either in close mutual orbit, or even stuck together.
Applied Technology Institute (ATIcourses) offers a variety of courses on Cyber Security. We thought the information below would be of interest to our readers.
Of all the keynotes at this year’s t3 Enterprise conference in Las Vegas, the one most illuminating and alarming was delivered by Isaac Ben-Israel, the chairman of the Israel Space Agency and head of the Israeli Ministry of Science, Technology and Space. A military scientist who is also a retired general of the Israel Defense Forces and former member of parliament, Ben-Israel presented his views on the development of artificial intelligence and the impact it has on the cyber threats that can lead to ransomware attacks or breaches such as the one Equifax experienced this year.
Using the Stuxnet virus, which took an Iranian uranium facility offline, Ben-Israel noted that real physical effects — in this case the collapse of the centrifuge machines — can result from “virtual” information such as the computer virus. This led him to propose four false dogmas relating to cyber warfare.
First, cyber warfare is not only about information, as evidenced by the Stuxnet virus.
Second, cyber warfare is not only about the internet — the Iranian facility wasn’t even connected to the internet.
Third, cyber warfare is not only about computers, as there was not a computer to be seen in the Iranian nuclear facility. Stuxnet attacked the centrifuge machine controllers instead of computers.
Finally, cybersecurity is not only about technology, as without taking into account the psychology of individuals and social behavior, legal problems or business considerations, one would not be able to choose the right technology to develop in the first place.
Ben-Israel says cyber security is simply the dark side of computing, and our industry is tasked with minimizing that dark side by taking preventative steps.
Enter artificial intelligence based on machine learning algorithms, now known as deep learning.
AI plays two distinct roles in the financial advisor community, first as intelligence to drive trading — Ben Israel estimates 95% of all trades in the exchanges are now computer-driven — and AI also is the underpinning of modern robo software that is increasing in popularity.
However, AI may play a bigger role in the future, as the engine in cybersecurity tools that help prevent socially engineered phishing attacks and viruses from impacting the machines and networks that increasingly are the lifeblood of businesses.
He left the audience with some points to ponder. “When we make a biological virus, we have to check that it won’t cause a pandemic,” said Ben-Israel. “But, we don’t have to do that for computer viruses.”
His final, echoing thought: “You have to run very fast to be one step ahead with cybersecurity … if you want to survive.”
Following up on our last blog and from a Press Release posted Thursday, October 26, 2017, by the JetPropulsion Laboratory:
When it comes to space exploration, many believe America must make a choice between having human “Astros” exploring the solar system or using robotic probes as planet or asteroid “Dodgers.”
NASA sees both approaches as essential to expanding the human presence in the universe. But that doesn’t mean that two of NASA’s centers can’t engage in a little friendly rivalry when it comes to their hometown baseball teams competing in the 2017 World Series.
Houston is home to both the American League’s Houston Astros and NASA’s Johnson Space Center (JSC), the hub of human spaceflight, while the Los Angeles area is home to both the National League’s L.A. Dodgers and NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, one of the pillars of robotic space and planetary missions.
On behalf of their respective centers, JSC Director Ellen Ochoa, who actually is a native Californian, and JPL Director Michael Watkins, who actually is a University of Texas at Austin alumnus, have decided the World Series deserves to be the subject of a little bragging rights wager.
So, here’s the contest: If the Houston Astros win the best-of-seven series, Watkins will have to wear an Astros jersey for a day. If the series goes the L.A. Dodgers’ way, Ochoa will wear a Dodgers jersey.
“JSC is proud to be a citizen of Houston, and, as such, we are proud of all the city’s accomplishments and its great spirit,” Ochoa said. “And our team is actually named after our space center, so I’m happy to be able to show support for that, and glad to have a little fun in challenging a center that, except for this week, is our close partner in exploration. I am looking forward to seeing a little bit of Houston at JPL soon.”
“JPLers are proud to work and live in the Los Angeles area here in beautiful Southern California,” Watkins said. “We love the chance to show our support for this great city, and for the great baseball tradition of the Dodgers. This is a nice way to have a little fun with our good friends at JSC and we hope to see some Dodger blue there shortly.”
When it comes to the reality of spaceflight, the two centers have collaborated and compared notes on a variety of space projects for nearly half a century. NASA understands that robotic exploration has always been a precursor to human space exploration and that more and more, we see robots and humans flying together, helping each other explore. Rather than rivals, JSC and JPL are close teammates in expanding our knowledge of the universe and increasing the limits humanity explores.
But in the meantime, JSC invites all Astros fans to “Orange Out” and JPL invites all Dodgers fans to “Bleed Blue.” May the best team win!
Last year, my colleague, Lisa Badart, wrote a post about the pride for her favorite team, the Chicago Cubs, winning the World Series. I commented on her post that I had predicted this win.
It’s important to note that, although I adore baseball, I am not particularly known to closely follow rosters, statistics, and standings to consistently make accurate predictions as to those teams who make it all the way to the World Series — let alone win the event.
However, on August 14th of this year, I wrote a text message to a friend that read, “My prediction for the World Series 2017, although it’s still early: Dodgers vs. Astros.” As a Los Angeles native, there is no doubt that my hope — based on their outstanding record — was that the Dodgers would play in the series.
Here we are today: game 2 ended last night in the 11th inning with the Astros winning the game and the series tied 1-1. Both games 1 and 2 were exhilarating and a number of my friends in L.A. were fortunate to attend and share the excitement with me through sounds and images.
We are all saddened by what occurred in Houston this year and I do wish the Astros the best. Nonetheless, I cannot deny that I would love to see the L.A. Dodgers win the series. Go Dodgers!
