What Would You Look For In A TPI Agency?

Hi folks.

Working for and with many TPIs through the years has given me many great experiences and a few heart burns because of their administration and technical departments lacks...

So, in addition to consulting, I am getting asked about providing TP Inspectors for a wide range of skills

Winter Cooling

Hello, I am looking into a project that would allow me to use the winter air to cool the cooler space at my DC. and I am wondering if anyone else has completed a project like this?

Penultimate Discovery landing set for 08:48 EDT | Bad Astronomy

The Space Shuttle Discovery is scheduled to land at Florida’s Kennedy Space Center Monday morning at 08:48 EDT (12:48 GMT).

ISS astronaut Soichi Noguchi took this picture of Discovery over the Caribbean as she undocked from the station and prepped for landing. After she lands, there will be one more flight for the Orbiter, scheduled for September. In fact, each of the Orbiters — Discovery, Endeavour, and Atlantiseach have one flight left before they are retired. Assuming their lives aren’t extended, but that’s still in the scuttlebutt (shuttlebutt?) stage.

sts131_groundtrackIf you want to watch this landing yourself, the de-orbit burn will be at 07:43, so stay tuned to NASA TV around then to find out if weather will permit it to touch down. The ground track is unusual this time, taking the Orbiter over most of the country. It’s a bit too far north to get a good view from Boulder, and it’s also a bit early for me… but I might try for it anyway. It’s not like there are many more chances to see it.

[Update: I just noticed that if the landing is delayed one orbit -- about 90 minutes -- then Discovery will pass almost overhead at my location (and it'll be at a more decent hour of the morning, too). Keep your eyes and ears open for news of when it lands, and check those ground tracks.]


% Impedance

what is the role of %Impedance in distribution Transformer? Is it very important to maintain some specific value like near about4%?

“Tech Hiring Binge” == “Fear for Your Job, Nerds”

At university, an exchange student fresh from Shanghai and I were watching television during dinner –but she was confused. Why all the political commercials? Wasn’t this considered crude in America?

“Oh yes, that’s why they work.” I told her. “You see, in America, nobody is better at propaganda than other Americans. It is our primary export! (Though we usually call it finance or marketing or business development.)

So excellent are Americans at propaganda —because, remember, Americans themselves pride themselves in ‘media savvy’— that the only kind of propaganda that really works is propaganda so painfully obvious that Americans could not believe that we ourselves could be fooled by such an attempt to fool us. We think we know better. Then, we are fooled.”

So unlike China or any places in the world, American propaganda is always true! —assuming you mean “true” to mean “not a lie.” To learn the real truth, simply assume all reported facts must be true, invert the connotation, and voila: the truth! Isn’t that great? A culture so dishonestly honest that all you have to do to know reality is to believe what is bad is good and what is good is bad for the exact same reasons why everyone else will disagree with you.”

“So…” she tries, “that’s how to be successful in America?”

“Oh no.” I laugh. “That’s how to be sure everybody will hate you. If you already aren’t wealthy, then you’ll almost certainly never be, because that’s the way the world is and always has been everywhere no matter what.”

And… that relationship didn’t last long.

By the way, did you hear? 23andMe is hiring. That is a fact.

…and thank goodness, because you know what else is a fact? That your medical insurance won’t pay for healthcare anymore. Nope! That was all those “cost saving initiatives” you all have been so excited about recently. Good thing that now you’re “empowered” to figure out medicine for yourself on the Internet. So long, and thanks for all the fish money intellectual property!

Drive for Gluing Applicator

I need design or evaluating purchase-if exist on market- a drive for electromagnetic gluer applicator that consist apply for a very little time 24 Volt DC -typically 3 micro seg- and then hold it with 5 Volt DC until .

Thanks in advance

Discovery Heads Home

Ground track for first landing attempt. Maybe you can see it! Credit: NASA

The shuttle Discovery has passed all the safety inspections will be coming home tomorrow morning (providing the weather co-operates – see below) and will be making what is known as a descending node entry.  Basically this means the shuttle will be moving to the southeast during the re-entry.  The descending node entry is quite rare, this is only the second one since the Columbia tragedy.

Provided the weather at KSC is acceptable:
If you live along the ground track (click on the above image to get a better look) you may be treated to seeing Discovery as it comes in for a landing at KSC at 8:48 am ET (the de-orbit burn occurs at 07:43 am ET).

Should the landing be delayed on orbit the de-orbit burn will occur at 09:17 ET with landing at KSC at 10:23 ET.  In the event of a second attempt the ground track shifts somewhat  and you can see it here.

If you are along the flight paths you should start looking about 40 minutes before landing on the northern end of the ground track, 20 minutes for points about half way mark etc.  I will post times if NASA releases them.  Heavens Above might also have them.

Here’s the NOAA forecast for KSC:

Tonight: Showers likely, mainly after 8pm. Mostly cloudy, with a low around 63. East wind between 5 and 10 mph. Chance of precipitation is 60%.

Monday: Showers likely. Mostly cloudy, with a high near 75. North northeast wind between 10 and 15 mph, with gusts as high as 25 mph. Chance of precipitation is 60%.

The weather may become an issue because among other things the following weather constraints apply:

  • Cloud cover should not exceed 25 percent coverage below 8,000 feet and must not be forecast to exceed 50 percent at landing time.
  • Crosswinds must be less than 15 knots if the landing is in daylight/12 knots at night.
  • No thunderstorms within 30 nautical miles.

Be sure to check the NASA Landing Blog in the morning for the latest.  I will update this post in the morning to reflect the landing status.  This is a great opportunity to see the shuttle overhead during the landing phase of the mission.  You may also see the pair (ISS and shuttle) fly over tonight, check Heavens Above for times.
