Infrared Portrait

Infrared Portrait

While going through some stuff we brought from the old house, I ran across an old Polaroid photo of myself as seen through a Forward Looking Infrared Receiver (FLIR). The FLIR was part of the optical suite of instruments destined to be the night vision system on the Abrams M1 Army Tank. At that time, I was a Member of the Technical Staff at Hughes Aircraft Company in charge of the design of display symbology for the system.

The imaging quality of the FLIR is not as bad as the photo makes it look. Bear in mind that the photo is over forty years old and is one of those old Polaroids that required a coating of “fixer” to keep the image from fading. The coating made the image look blotchy.

That is my infrared signature as I posed, arms folded, in front of the FLIR for the photo. The image is “white hot” which means that the warmer temperatures are brighter. You can see the lenses on my glasses are a little darker than my face because they are somewhat opaque to FLIR detectors. The three horizontal lines are due to three dead channels in the IR detector array. The targeting reticule (my design) in the lower right is one of several symbols displayed in the image and is computer controlled to position itself at a point in the image where a fired round from the big gun would hit.

The Abrams tank saw action in Operation Desert Storm. The targeting FLIR easily found and knocked out several of Saddam Hussein’s Russian tanks of the so-called “Republican Guard” long before they saw our forces approaching in Kuwait. I take pride to know that between the Abrams and Hellfire Missiles, both systems of which I had designed in part, some of the Iraqis were forced to retreat back across the border and out of Kuwait.

ISS Pass at Dusk

ISS Pass at Dusk

I’m just getting around to posting about the International Space Station (ISS) passing over the Arizona High Desert last week. It was a pretty good pass, the ISS being visible almost from the west horizon to the southeast horizon. The maximum elevation above the horizon for this pass was 78°.

We use the on-line SpaceWeather.com satellite flybys tracker to predict when a suitable satellite pass will occur. We use the filter function to display only the ISS, since those are usually the most dramatic flyovers.

The remarkable thing about the photo is that I candidly snapped the flyover using my less-than-optimum pocket camera, a Canon PowerShot A1400, and got this relatively good image of the ISS as it passed high over the parapets of our little house. Click on the image to enlarge.

A Personal History

Planner

I attended a time management seminar as a requisite to becoming a senior technical group leader when I worked in the aerospace industry in 1991. The seminar was based on the popular Franklin Planner organizing tools.

For over fifteen years, I faithfully recorded notes, personal and vocational goals in my planner. I retained the records in binders, one for each year I used the system. I was organized, believe me.

As we cleaned out the old stuff from the house in California after completing the sale, I elected to bring my volumes of planner with us to Arizona, so I could review, and dispose of the old notes as appropriate.

There were a lot of important events I recorded. I looked in the initial 1991 volume today and found the page where my first grandchild was born. That was the granddaughter who just recently gave birth to my first great grandson last month.

It will be conflicting to me, but, since we don’t really have a place to store them, I will probably gather them up and have them shredded. Way too much personal and potentially dangerous (i.e. identity theft) information. Nothing too incriminating . . . 😉

Observing ISS Passes Overhead

ISS

For the last couple of days, we have been getting overhead passes of the International Space Station suitable for observing at dusk or a little after. The satellite tracker from SpaceWeather.com allows us to input a zip code and it will return a listing of satellite passes observable from the location selected. The tracker has the option of selecting a subset of satellites and in our case, we selected passes from the ISS since they are usually more dramatic and bright as compared to most other orbiting objects.

Last night and tonight, we had very good passes and, weather permitting, we should have two more, tomorrow and Monday evening observable overflights. In the image above, I halfheartedly snapped a photo of Friday night’s pass of the ISS and damned if it didn’t show up when I downloaded it to the computer. Click on the image to enlarge.

UPDATE (08/24/2014): Damsel and I went out again this evening to see the overflight of the ISS. We saw it, alright, but the display of stars and the Milky Way dominated the night sky. As the ISS flew from west-northwest toward the southeast, it encountered Arcturus, the constellation Scorpio and then winked out across the terminator as it entered the Milky Way. What a spectacle! We love our dark desert skies!

ISS HD Earth Viewing Experiment

Southeast Asia

This is an interesting thing to watch live streaming from the International Space Station. It is a high definition view of the Earth below taken from one of four HD cameras aboard the ISS. I screen captured the image above of somewhere over Southeast Asia as the ISS sailed off to the south pacific. Read the entire description of the experiment at APOD.

This is a good site to find out the current location of the ISS. Click on the image to enlarge.

UPDATE: I watched the streaming video as the ISS approached the terminator and was surprised to see the full moon rising in the distance.

Full Moon Rising

UPDATE II: This is looking back at the setting moon at about 1815UTC 5/16/2014 as the ISS passed into western Canada.

Mars Rover Opportunity Tenth Anniversary

Opportunity

Originally envisioned as a three-month Martian experiment, rover Opportunity managed to exceed its lifetime projection forty fold. I missed posting this yesterday, so here it is today.

From APOD and NASA:

On January 25 (UT) 2004, the Opportunity rover fell to Mars, making today the 10th anniversary of its landing. After more than 3,500 sols (Mars solar days) the golf cart-sized robot from Earth is still actively exploring the Red Planet, though its original mission plan was for three months. This self-portrait was made with Opportunity’s panoramic camera earlier this month. The camera’s supporting mast has been edited out of the image mosaic but its shadow is visible on the dusty solar panels arrayed across the rover’s deck. For comparison, a similar self-portrait from late 2004 is shown in the inset. Having driven some 39 kilometers (24 miles) from its landing site, Opportunity now rests at Solander Point at the rim of Endeavour Crater.

Mars Rover Opportunity 10 Year Anniversary

Today marks the tenth anniversary of the deployment of the Mars Rovers, Spirit and Opportunity. Spirit has not been heard from for several years, but Opportunity keeps on chugin’ along. This is quite an achievement for JPL, NASA and the subcontractors that put these remarkable spacecraft together. Several years ago, Damsel and I visited JPL and took the tour that included the ground facilities for the rover program. It was quite impressive.

Here is an excerpt from Dr. Tony Phillips’ article about Opportunity:

Opportunity’s Improbable Anniversary

July 1, 2013: When NASA’s Mars rover Opportunity blasted off from Cape Canaveral in 2003, many onlookers expected a relatively short mission. Landing on Mars is risky business. The Red Planet has a long history of destroying spacecraft that attempt to visit it. Even if Opportunity did land safely, it was only designed for a 3-month mission on the hostile Martian surface.

Few, if any, imagined that Opportunity would still be roving the red sands of Mars–and still making discoveries–ten years later.

On July 7, 2013, Opportunity celebrates the 10th anniversary of its launch and more than 9 years on Mars.
