Saturday May 15 2021

This may finally be the day we get to see the rocket launch and upper atmosphere experiment NASA has been waiting for. It has been over 1 week of weather and technical delays.  Today the weather looks good, as we will see below. As of this afternoon, the launch is a GO!

If the rest holds out, then we may get the sky show in the eastern US.

Planned Launch Time at 8:10 PM, but there is a 40 minute window.

Here you can see the weather conditions, forecast and also the Live Video Stream of the NASA Broadcast. That should begin at 7:40 PM.


Satellite Loop: Saturday Afternoon 4 PM to 6 PM

The coast was mostly clear. Inland clouds build up with the afternoon heat, should diminish as the sun gets low again toward sunset.

Rocket Viewing

Launch visible shorty after lift off.

Face East/Southeast: To the ‘right’ of where the sun has been rising recently.

If the sky is clear, then you may see a light streak within 1 minute across much of our region as presented in this map.

The high altitude light show will begin 9 minutes later.



This rocket is designed to created an artificial aurora high in the atmosphere to test high altitude conditions. Basically for us it will be a display of bright lights more than 200 miles above the ground.

This was postponed each day since Friday due to weather. Winds need to be light enough, along with clear skies for cameras in Wallops Island and Bermuda to observe the artificial aurora.  When this occurs, the eastern US should have a chance to watch the rocket and the high altitude sky show.



Live Stream: NASA-TV Wallops

Live Coverage begins at 7:40 PM. There is a delay that can range from 20 seconds to up to 1 minute.




Vapor Tracers: What You May See

About 9 minutes after launch, the payload of vape tracers will be released,

217 to 249 miles above the ground of Bermuda.

This is made up of the dame material in fireworks.


Barium Vapor: This will form two green-violet clouds that may be visible for about 30 seconds.




Scientists use vapor tracers primarily to study atmospheric winds in upper atmosphere and ionosphere. When released after launch, the tracers make it possible to directly observe the winds.



If this does NOT occur tonight, they have more opportunities in the days ahead.  We would want a clear sky for much of the Mid Atlantic (and East Coast) for more to be able to view this.

Sunshine State Of Mind

I am done with the cold and snow (for the season). I am embracing my wife’s mantra of Sunshine State of Mind.

This was designed by Shannon Berk and we will be wearing it through spring and to the beach.

Double Benefit: Proceeds will be split between our nonprofit Just In Power Kids and the development of my new weather website. That has been scheduled to be ready to launch in May.
