CUMBERLAND, Md. — It is a chilly March morning, and Mary Bowden is standing within the parking zone of a local people faculty.
Bowden is a professor of aerospace engineering on the College of Maryland. Close by, her college students are hustling round on a brilliant blue tarp, rolling out heavy cylinders of compressed fuel and fidgeting with bins of electronics.
“That is our closing, closing costume rehearsal,” Bowden says as she surveys the scene.
At first of subsequent month, a complete photo voltaic eclipse will sweep throughout the continental United States. It would start in Texas and transfer north by means of a dozen states earlier than exiting the nation by means of Maine and into Canada.
On eclipse day — April 8 — dozens of pupil groups throughout the nation will launch a whole lot of analysis balloons. The balloons will carry lengthy, dangling strings of scientific devices into the trail of totality, the world on Earth’s floor that may see the moon fully block the solar.
The trouble, often known as the Nationwide Eclipse Ballooning Project, is backed by NASA. It is a chance to make distinctive atmospheric measurements that may solely be performed throughout an eclipse, and an opportunity for college students to study expertise they could sometime use to launch satellites and astronauts into orbit. Bowden is guiding the College of Maryland staff, which is made up of about 30 to 40 college students.
“It is only a membership,” says Daniel Grammer, a junior who can be main the staff on eclipse day. “Everyone right here volunteers to do it as a result of they love to do it.”
Floating laboratories
Deflated, the balloons appear to be big occasion balloons. As they fill with helium, they start to take form — two white, upside-down teardrops bobbing gently within the spring air.
Saimah Siddiqui is a senior on the College of Maryland. She hopes her work on balloons will finally result in a profession in mission management.

Saimah Siddiqui is a senior and one of many “inflation leads” accountable for filling the balloons.
“The place are we at?” she asks as one other pupil bends over the regulator of the helium tank. Siddiqui appears assured, and with good purpose.
“I’ve performed this so many instances — that is most likely my thirtieth launch or one thing,” she says.
The scientific aim of this challenge is to review the environment. Because the eclipse shadow travels from south to north throughout the U.S., it briefly cools the air. Bowden says it is like dragging a swizzle stick by means of a cup of sizzling espresso.
“The eclipse itself is form of stirring up the environment because it traverses throughout the nation,” Bowden says. “What we’re on the lookout for is the signature, or the impact, of the motion of the shadow.”
Balloons are an ideal strategy to prepare college students: “It is a microcosm of a NASA launch, however low-cost and quick — and you are able to do it once more in the event you fail,” says Mary Bowden.

The outcomes will educate researchers extra about how warmth strikes by means of the environment. The information might be used to enhance predictions of each climate and local weather change.
In terms of making these measurements, there is no higher automobile than a balloon. Not like a rocket, balloons can drift gently within the eclipse zone for minutes or hours. And so they journey at 75,000 to 80,000 ft in altitude, twice the altitude reached by a typical airliner.
Grammer says the view must be superb.
“Hopefully we’ll have livestream video from the balloon in flight,” he says. “You may see the shadow transfer throughout the Earth, and it will be tremendous cool to take a look at.”
Runaway balloons
Issues on the check launch look like going easily, however then, as Siddiqui begins to verify her balloon to verify it is obtained sufficient lifting energy, it immediately breaks free and floats skyward.
Daniel Grammer, a junior, would be the flight director for the photo voltaic eclipse launch on April 8. “Everyone right here volunteers to do it as a result of they love to do it,” he says.

The entire staff watches as certainly one of their two balloons drifts slowly away.
No one panics. The scholars put their heads collectively to determine what occurred. It seems they forgot to reset a tool that’s supposed to chop the string on the finish of the flight. Usually, this enables the balloon to drift away, and the scientific gear to parachute again to the bottom, the place it may be recovered.
As a substitute, the gadget minimize the balloon free earlier than the payload was even hooked up.
“I’ve by no means seen that occur!” Meredith Embrey says with fun. The junior is in command of tying the scientific gear to the balloon.
“The great factor is, we did not lose the payload itself, and we at all times deliver two spare balloons and double the quantity of helium we want,” Embrey says. “So we’ll begin inflating and do one other balloon.”
It is a second to study from, and that is precisely the purpose.
Balloons are the right automobile to review an eclipse. They fly larger than plane, and might keep within the eclipse zone longer than a sounding rocket.

“The wonderful thing about this system is that it is actually each an training program and a analysis program,” says Angela Des Jardins, a physicist at Montana State College and the principal investigator of the Nationwide Eclipse Ballooning Venture.
Throughout the U.S., over 750 college students making up 53 groups are collaborating on this challenge. The budding engineers are in command of all the things from scientific devices to flight course, climate forecasting, monitoring stations, and extra.

“We’re attempting to provide these college students a chance exterior the classroom,” she says. The eclipse balloons are “a science challenge that offers them a bit of little bit of a style of what it might be like in the true world, working in an aerospace job.”
Balloons are an ideal prelude to launching rockets, says Bowden. “It is a microcosm of a NASA launch, however low-cost and quick — and you are able to do it once more in the event you fail.”
Which is strictly what the staff is doing now. With their string-cutting gadget fastened, they’re racing to inflate one other balloon. They have to be fast as a result of the wind is choosing up. Siddiqui appears to adore it — utilizing engineering to unravel issues on the fly, below stress. She says she hopes to sometime have a profession launching rockets.
“Possibly like a flight controller/flight operator-type particular person for my full-time job,” she muses as she watches the second balloon fill.
In the meantime, Embrey and her fellow tie-on specialist Dan Gribok are doing closing checks on the scientific devices. They use crimson tape to shut up the bins that maintain the cameras, measuring units and transmitters.
College students prepared their payloads forward of the flight. The gear consists of cameras, monitoring units, and sensors to observe circumstances excessive above the Earth.

“Duct tape is an engineer’s finest buddy, for positive,” Grammer jokes as he appears on.
Liftoff!
The radio crackles because the flight director, a spirited senior named Kruti Bhingradiya, calls out orders to the staff.
“I hope you guys are prepared, and in the event you’re not, let me know proper now,” she says.
The payloads are tied to every balloon. Different college students stand round, arms outstretched in direction of the floating spheres to verify they do not bang into something within the closing moments earlier than launch.
Bhingradiya requires the launch space to be cleared of particles. Then she appears round. The staff is prepared.
“Three … Two … One … Launch!” she says.
And the scholars cheer as they watch their arduous work drift off into the clouds.
