High Hopes Launch 11/28/2017

High altitude ballooning, science and STEM

We finally managed to launch a balloon this fall. It’s been in the works for well over a month, maybe two. Weather and scheduling finally came together and we launched on Tuesday, November 28, 2017, from Virginia City High School‘s football field (in Nevada). Virginia City is best known for being home to Mark Twain, who lived, worked and wrote here in the 1860’s, the Comstock Lode gold and silver rush, as being one of the settings for the old Bonanza TV show and a rich history.

We launched about 8:30AM – it was hovering around the freezing mark and the sun was just high enough to start warming us a bit. Teacher Sarah Richardson had the honors to release the balloon after a quick countdown. Besides  3 of our GoPro cameras and various data loggers and communications gear, Sarah’s students had designed a payload to release the “high hopes” of the world we’d collected … including their own (over 700 high hopes were included in their payload) so they were intrigued to see how this whole launch thing works. The “outlooking camera” recorded this:

And the “downlooking camera” recorded this:

This launch was mostly about giving Sarah and her students some experience in how this works. The plan is now for them to design various payloads to carry out science and engineering investigations this spring … that will give them plenty of time to prepare. They designed the payload we launched by breaking into groups that each built a payload to release the high hopes which are printed out on small strips of paper. They then had trials that led to choosing the one we launched. They’ll use what they learned about payload construction and I will be visiting class to facilitate them through the process some, but most of that will fall to Sarah. Here is what the balloon burst looked like at 26,000 meters (85,000 feet) a bit less than 2 hours after launch:

In Quicktime you can play the video frame by frame which is awesome! You miss a lot in real time … besides the hunks of balloon that float by you can see high hopes fluttering through the air and one comes right at the camera and you can read it – “people everywhere” … because it is handwritten it must be one from Sarah’s class (the others were printed out) – I’m hoping we find out which student wrote it.

Folded “High Hope” with the words, “people everywhere” clearly visible – hope to find out what the rest said. About 85,000 feet, that’s Pyramid Lake in the middle of the screen shot.

I’ll be uploading some of the photos we took to Flickr when I get the chance and I’ll add a link to them.

UPDATE: Here is a link to a Flickr set of launch and recovery photos

Chasing Triton’s Shadow – Neptune’s Moon Will Cast Shadow on Earth

SOFIA can travel where the action is

A few weeks back I travelled with a NASA sponsored team to Idaho to launch high altitude balloons during the recent total eclipse. We sent up various cameras, data recorders and more (even an Idaho potato) to record data and media at high altitude during totality (being up above any possible weather or smoke is an added bonus). We travelled to Idaho from Reno and Las Vegas because that was where totality would occur. We only would have experienced a partial eclipse if we’d stayed home and would have missed out on important data you can only record during totality. Since then we have shared almost all the data and media we recorded and will continue to do so.

Partly because of that experience (and other NASA projects I’ve been allowed to be part of), my experience with the RECON project and because my job requires me to have a social media presence and share resources and experiences via those connections, NASA recruited me to take a flight on SOFIA (Stratospheric Observatory For Infrared Astronomy). My flight is scheduled for September 25th – here’s the observation plan for that night. Needless to say I’m thrilled and honored to have this opportunity!

SOFIA over the Sierra Nevada Mountains.

I’ve been told we will takeoff about 7:00 PM and not land until 5:00 AM the next morning, so 10 hours in air.

SOFIA’s infrared telescope weighs in at 19 tons (38,000 pounds) and was built in Germany.

SOFIA is a modified Boeing 747SP. Note the large door in it’s side that when open exposes a 2.5 meter (100 inch) wide reflecting infrared telescope to the sky.

So why put a telescope in a 747 and fly all night recording data? Seems expensive for something you can do on the ground from much larger telescopes.

SOFIA generally flies between 12,000 and 13,000 meters (39,000 and 43,000 feet), and that is important. It’s important because at those altitudes you are above most of the Earth’s atmosphere and humidity. The “Twinkling” of the stars in the sky experienced from the ground is caused by the starlight traveling through the atmosphere’s humidity and variations in temperature. You are also above clouds, most air pollution and other factors (like bad weather) that limit grounded telescopes from obtaining a clear view (also why the Hubble space telescope gets such awesome observations even though it is much smaller that many ground based telescopes on Earth).

A huge advantage SOFIA has over ground based telescopes is that it can go where the action is  – like when it travelled to New Zealand to capture Pluto’s occultation of a star

 

 

 

ANNNND it will travel to the US east coast on October 5th to Chase Triton’s Shadow over the Atlantic Ocean.

From SOFIA’s media outlet: “As Neptune’s moon Triton passes in front of a distant star, it will cast a faint shadow on Earth’s surface. The team of researchers will carefully map the path of that shadow and then fly into it to study Triton’s atmosphere, directly, for the first time in 15 years. SOFIA will takeoff from Florida to catch the shadow that will fall over the Atlantic Ocean. The shadow is moving; the plane is moving; and the predicted path may change in flight, making catching the shadow very challenging. Researchers are trying to determine if Triton’s atmosphere is expanding or collapsing and if haze last seen by the Voyager mission is still present.” triton-final[1][1][1] (link to flyer)

I won’t be on the flight chasing Triton’s shadow (it happens over a week later than mine), but that gives me the opportunity to pass on what I learn about SOFIA in preparation for the October 5th flight. I will be presenting about Chasing Triton’s Shadow and SOFIA locally in Reno and I’m available to visit local schools and even video-conference in pretty much anywhere.

 

 

 

 

 

 

 

 

 

 

I’ll be adding more posts about SOFIA soon and you can follow me on Twitter @bcrosby. I’ll be uploading photos to FLICKR as well, I’ll post the link when I post photos.

Photos, Video and DATA from the Eclipse Balloon Project

Total Eclipse 2017, Camas ID, USA, by Dr. Jeffrey LaCombe

I’ve been back for awhile from our Eclipse Balloon Project launches. We’re still processing data we recorded from cameras and data loggers from 3 HAB balloon launches outside of Twin Falls, Idaho, (really from Camas, Idaho), but wanted to share some of the incredible visuals. Click on any photo to see enlarged.

This is the shadow of the Moon from about 23,000 meters (75,000 feet)

Video of the shadow moving across the Earth’s surface :

The prediction was very accurate – this is actually 10 predictions on one screenshot – yellow dots are predicted burst and blue predicted landing spot:

I did send up a small solar panel attached to a voltage data logger. We usually do this to record data on what happens to the voltage as the panel gets higher and much colder. But this is interesting for obvious reasons:

 

Note the voltage goes up as the altitude rises over time … then “something happens” that causes the voltage to drop to almost zero.

This balloon came down within sight of a temporary command center of sheriffs and other emergency personnel that had been set-up to help with the crowds and any issues that may have arisen. You’ll note that at the end of the data it seems to have gotten dark again. The sheriff investigated what had landed  nearby and picked up our payload and placed it in their command vehicle until we showed up. Once we had described it they briefly handcuffed Dr. Wang and I for endangering the public … then had a good laugh and took the handcuffs off.

Dr. Eric Wang and I handcuffed with our payloads in hand.

 

 

 

 

 

 

 

 

 

Nothing too surprising about our temperature readings – at 28,000 meters (92,000 feet) it was about -42C :

 

 

 

 

 

 

 

 

I have other data as well I might post later.

We successfully launched 3 balloons – one got to over 110,000 feet, but we also had 2 balloons pop on the ground during and just after inflation – one seemed defective, the other probably got stressed in the relatively high winds at the launch site and popped just as we were connecting payloads. Fortunately we had enough gas to fill 2 more balloons.
