|Message from Jim Sipes, Chair, IEEE Denver Section, Jim Sipes – firstname.lastname@example.org
Well, a new year, and hopefully a new beginning. We hope the current downward trend of Covid continues…
Some other good news —
The IEEE Fellows Class of 2022 has been released, and four members of the Denver Section are included. The new Fellows are:
Congratulations to all!
The most recent meeting of the panel that reviews applications for elevation to Senior or Life Senior Member met on February 19th. Although the official list of those elevated was not available at the time of this writing, my preliminary analysis indicates that we have nine new Senior Members in the section. I’ll update this next time when the official results are available, but, again, congratulations to all of the new Senior Members!
The next meeting of the SM panel will be on April 23, and applications for consideration must be in by April 16. If you are interested and feel you are eligible for the upgrade, the requirements are set out on the IEEE website at https://www.ieee.org/membership/senior/senior-requirements.html, and we have a list of existing Senior Members who have volunteered to serve as references for those seeking the upgrade. If you want to proceed, please contact me at email@example.com or Jeff Hardy at firstname.lastname@example.org.
Speaking of appointments and elevations, at the February meeting of the Section Executive Committee, the ExCom voted to approve Jeff Hardy as Chair-Elect. So at the beginning of 2023, Jeff will take over this chair. Congratulations to Jeff!
And while we’re on this topic, in late summer our current Past-Chair, Jason Rupe, will be canvassing the section for candidates to stand for Section Officer positions in our fall elections. So, if you are interested in becoming involved at the Section level, be thinking about if you would like to throw your hat in the ring.
You should have by now received the premier issue of the Region 5 newsletter. This monthly newsletter is part of the new Region 5 Director, Bob Becnel’s, plan to improve communication within the region. Another way to stay connected with the region is by joining the Region 5 IEEE Collabratec Community. This Collabratec Community is open to all members of Region 5. More details at https://ieee-collabratec.ieee.org/app/community/1314/IEEE-Region-5/activities.
As always, we continue to have many opportunities to contribute as a volunteer to the Section or your Chapter/Group of choice, and all are welcome at the monthly ExCom meetings on the third Tuesday of the month (except December and July). I am hoping that beginning with the April meeting we can go to a hybrid format with some attending face-to-face but with an online virtual option as well. There is a listing of the current chapters and groups supported by the Denver Section on the Section’s website, https://ieee-denver.org, under the menu heading Denver Groups. Contacts for each of the chapters/groups are available on the individual chapter/group websites.
Until next time, stay safe.
When I first read that a batch of Elon Musk’s satellites got fried in a geomagnetic storm I had to chuckle. But all humor aside, we seem to forget, sometimes, that there are risks to satellites as well as benefits from them.
My first thought was, “how is it that Starlink loses satellites and nobody else does?”. It seems that same geomagnetic storm had to hit other satellites as well. Were the Starlink satellites the only ones in the direct path? The size of the storm was massive, much larger than the size of the earth, so it seems unlikely no other satellites were in the path. Yet Starlink’s were the only ones affected.
This was all over the news, syndicated networks, the BBC, CNBC, Yahoo, streaming news outlets, some industry publications, even YouTube. I guess this garnered more attention than I would have surmised. But, when one thinks about it, this is something that can present significant issues with wireless data reliability, cybersecurity – perhaps even to life and limb in the future if the number of satellites predicted comes to fruition.
Today, as we are all aware, the satellite industry, particularly the non-geostationary orbit (NGSO) Systems, or LEOs, is making a big-time play for a piece of the wireless network pie. It sees itself as becoming an integral component of the wireless ecosystem, particularly with 5G and even more with B5G.
If these NGSO satellites want to be of the wireless future, they have some interesting challenges to address. Perhaps the most pressing is falling out of the sky for one reason or another.
First of all, when all is said and done, some in the industry say there could be 100,000 satellites of all types up there by 2030 (according to astronomy.com). That is a boatload of space hardware. Granted, space is pretty big, but I have to think that with that kind of density in the same orbit space things are going to get messy at some point.
While there has not been much said publicly about this, one issue that is becoming very visible is the risk of collision, both with other satellites and with space junk. Warnings are beginning to sound.
NASA is raising red flags with Starlink’s ambitions to orbit 30,000 plus NGO satellites. In a recent letter to the FCC, NASA wrote that “With the increase in large constellation proposals to the FCC, NASA has concerns with the potential for a significant increase in the frequency of conjunction events and possible impacts to NASA’s science and human spaceflight missions.” Cool, now we are calling collisions “conjunctive events.” Oh well, another government moment of terms to make it sound like a non-issue.
But imagine the potential challenge of keeping 100,000 active satellites if predictions are correct, from getting tangled up with each other, or space debris.
According to astrobites.org, with just 65,000 satellites in NGSOs, the odds of a collision with a relatively large (>1 cm) fragment, which would cause severe damage to a spacecraft in a collision, would be roughly 30 percent. Taking into account smaller fragments down to 3 mm, this probability approaches 100 percent. So, this becomes a front-page issue since it will be an ongoing condition.
Add to that derelict satellites (currently there are over 2200 non-operational satellites still up there), planet fragments, other space junk, aliens (hopefully they can vaporize them with their disruptor beams before they pummel their spacecraft), the odds of avoiding a conjunctive event are slim to none.
Voices are being raised. In fact, some of those voices have been raising for years, even before the first conjunctive event in 1996. That was when an Iridium 33 satellite and the defunct Cosmos 2251 satellite became V’ger (watch Start Trek, the Motion Picture if this does not ring a bell) at an altitude of 470 miles. Fast forward to today and there was the recent incident between the Chinese space station and a Starlink satellite. Nothing happened but it was close enough to be a close call.
There have been other satellite-to-satellite as well as some satellite-to-space rock, collisions. So far, the number is not significant, but when 60,000 to 100,000 birds are flying around up there, it would be foolish to think it is not going to happen and become a major concern.
So, what happens when a satellite is banged by something? Sometimes, nothing. Other times the event may kill it, or part of it but it remains in orbit. Or it may shoot off into deep space or end up hurtling towards the earth, with everybody hoping it burns up in the atmosphere (which happens most of the time but not always).
The worst case is that the conjunctive event sends it careening off, uncontrollably, in one of the NGS orbits or another populated orbit. What if that worst-case sets off the e+at scenario? In other words, it starts a chain reaction, and we have satellite billiards.
So, are there solutions? For the immediate future (a couple of years, or so), we probably do not have a lot to worry about. However, if even half of the 100,000 satellites end up there, it will be a problem.
The industry has been working on various collision avoidance programs because that is about the only solution (or shoot the offender out of the sky with onboard laser or missile systems).
All kidding aside, there are lots of ways to go about that but only one outcome – move them out of harm’s way – however that gets accomplished.
Ultimately, one wants the satellites to be “smart,” be aware of each other, and play nice when it comes to keeping track of one another. That will certainly have to come about, and they can adjust orbits dynamically as conditions demand without human overwatch.
But the real issue is about objects that do not have self-awareness. That is a problem in the autonomous vehicle space as well. So, these satellites will not only have to know where everybody is but be able to spot that two-mile-wide space rock heading right for it (at a leisurely 25 km/sec). Or human space debris from a just-occurred, nearby conjunctive event. Maybe even have to dodge that recent flush of frozen human waste from a spacecraft or station.
Of course, using radar and other sensing platforms should provide pretty good protection. But what if that one in a hundred, or thousand, or million, event happens? Is there a scenario for a mass failure of devices such as the recent 40 or so Starlink satellites summarily executed by the geomagnetic storm?
What if such a coronal mass ejection (CME) takes out hundreds or thousands of satellites? Sure, there is hardening against, and a priori knowledge of, such events but what if the CME so often played out in sci-fi films actually comes about. Will it be possible to move thousands of satellites behind the earth in time, perfectly orchestrated? Indeed, food for thought.
Recently, Samantha Fonder, NASA representative to the Commercial Space Transportation Interagency Group said that “With the potential for multiple constellations with thousands and tens of thousands of spacecrafts, it is not recommended to assume propulsion systems, ground detection systems, and software are 100 percent reliable, or manual operations (if any) are 100 percent error-free.” Hear, Hear.
There is also concern from NASA about auto-maneuver capability. What if multiple constellations are auto-maneuvering in a panic while a CME is on its way? Can the industry put together a plan, with sufficient technology and cooperation among players, to orchestrate that flawlessly?
So as one can see, the satellite space is far from having its ducks in a row. And this missive is just about collisions. There are all kinds of other challenges such as telescope interference and light reflections from satellites. As well, there is quite a bit of infighting going on in the industry.
It will be interesting to see this unfold. And who knows when the predictions for tens of thousands of satellites will come true.
The industry has a chance to get it right, still. The question is, of course, will they?
Life Member Group Update
As 2021 ends, I felt that a short update on Life Member activities would be in order. The bottom line is that the Denver Life Members have pretty much holed up while the COVID pandemic continues to target our age group. As a result, our technical meetings have all been virtual events that were shared among the other R5 LMAGs. We did, however, make one attempt at an in-person event. This was a joint event with our friends in Colorado Springs. The Pikes Peak Chair summarized the event as follows:
“On 12 June 2021, LMs from the Pikes Peak and Denver Sections toured the National Museum of World War II (WWII) Aviation located in hangers at the Colorado Spring Airport/Peterson Air Force Base (AFB). The museum highlighted 18 fully restored and flyable WWII aircraft along with military vehicles used during the war. The museum documents the role that military aviation played in the emergence of our nation as a world power. It tells the story of the tremendous technological advancements in aviation during WWII and the contributions and sacrifices of the men who won the air war. Our tour guide was Colonel Jim Palmer, Air Force Retired, former commander of the Third Space Support Wing, based at Peterson AFB. The LMs had lunch following the tour at the Airplane Restaurant, which is located near the airport. This unique restaurant is partially housed in an Air Force tanker airplane.”
