NASA Sounding Rocket Observing Nitric Oxide in Polar Night

UPDATE  January 27, 2020: The Polar Night Nitric Oxide or PolarNOx experiment was successfully launched fr om the Poker Flat Research Range in Alaska at 8:40 a.m. EST, Monday, Jan. 27, 2020.  The NASA Black Brant IX sounding rocket carried the payload to an altitude of 161 milesPreliminary reports show that good science data was obtained.


Aurora, also known as the northern lights, are a sight to behold as they dance across the sky when solar winds collide with the Earth's atmosphere.

However, they also contribute to a process that has an adverse impact on the Earth's ozone as nitric oxide is created during the auroral light show.

To better understand the abundance of nitric oxide in the polar atmosphere, NASA will launch the Polar Night Nitric Oxide or PolarNOx experiment fr om the Poker Flat Research Range operated by the University of Alaska, Fairbanks.

PolarNOx will fly on a NASA Black Brant IX suborbital sounding rocket between 8:04 and 9:04 a.m. EST (4:04 and 5:04 a.m. AST) on Jan. 26, 2020. The launch window runs through Feb. 8 and opens 3 – 4 minutes earlier each day.

Scott Bailey, PolarNOx principal investigator from Virginia Tech in Blacksburg, Virginia, said, "The aurora creates nitric oxide (NO), but in the polar night, unlike the sunlit atmosphere, there is no significant process for destroying the nitric oxide.  We believe it builds up to large concentrations. The purpose of our rocket is to measure the abundance and especially the altitude of peak abundance for the nitric oxide. We don't know the altitude at which the nitric oxide settles."

"Nitric oxide under appropriate conditions can be transported to the stratosphere wh ere it will catalytically destroy ozone," Bailey said. "Those changes in ozone can lead to changes in stratospheric temperature and wind and may even impact the circulation near Earth's surface."

Nitric oxide in the northern regions exists between 53 and 93 miles altitude. During the rocket flight a star tracker will lock on to the star Gamma Pegasi.

"PolarNOx will observe starlight with a high spectral resolution UV spectrograph operating near 215 nanometers. Attenuation of the starlight by NO is used to obtain an NO altitude profile," said Bill McClintock, co-investigator and lead instrument scientist from the Laboratory of Atmospheric and Space Physics, University of Colorado in Boulder.

"The payload with the spectrograph is targeted to fly to an altitude of 161 miles. The goal is to get the most time possible observing both the star brightness above the nitric oxide and wh ere the peak NO exists between 62 and 68 miles altitude," McClintock said.

This is the second flight of PolarNOx from Poker Flat. "In 2017 we experienced an electronics failure during the flight. While we did get the important part of the data, the mission wasn't a total success. We did upgrade the electronics for this reflight so we look forward to a much more successful mission," Bailey said.

The University of Alaska Fairbanks Geophysical Institute has established a subscription-based text messaging service for anyone interested in receiving updates and links to launch range communications or stream broadcasts. Subscribers also will be notified when the count drops below T-10 minutes, at which time a launch is likely to occur. To subscribe to the messaging service text PFRRLAUNCHES to 33222.

PolarNOx is supported through NASA's Sounding Rocket Program at the agency's Wallops Flight Facility at Wallops Island, Virginia, which is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. NASA's Heliophysics Division manages the sounding-rocket program for the agency.

ЦитироватьLaunching Rockets Through the Leak in Earth's Atmosphere - Trailer

NASA Video

27 апр. 2020 г.

In the tiny Arctic town of Ny-Ålesund, where polar bears outnumber people, winter means three months without sunlight. The unending darkness is ideal for those who seek a strange breed of northern lights, normally obscured by daylight. When these unusual auroras shine, Earth's atmosphere leaks into space.

NASA scientists traveled to Ny-Ålesund to launch rockets through these auroras and witness oxygen particles right in the middle of their escape. Piercing these fleeting auroras, some 300 miles high, would require strategy, patience — and a fair bit of luck. This is their story.

With DUST-2 Launch, NASA's Sounding Rocket Program is Back on the Range

NASA is preparing for the first launch of a sounding rocket since the coronavirus pandemic began in the United States. The DUST-2 mission, which is short for the Determining Unknown yet Significant Traits-2, will carry a miniature laboratory into space, simulating how tiny grains of space dust – the raw materials of stars, planets and solar systems – form and grow. The launch window opens at the White Sands Missile Range in New Mexico on September 8, 2020.

DUST-2, a collaboration between NASA and the Japan Aerospace Exploration Agency, follows up on the DUST mission launched in October 2019. Like its predecessor, DUST-2 will fly on a sounding rocket, a suborbital rocket that makes a brief trip into space before falling back to Earth. Sounding rockets provide cost-effective access to space and remain one of the most efficient ways to achieve near-zero gravity, a critical requirement for the mission.

DUST-2's goal is to study how individual atoms, shed by dying stars and supernovae, stick together. When they do, they form dust grains – some of the basic building blocks of our universe.

"What we're trying to do is duplicate what happens in at least two astrophysical environments," said principal investigator Joe Nuth, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "One is when [dust] grains form when stars die, as they blow off their outer atmospheres. The other is during the formation of solar systems, where you're actually forming planets from the vaporized dust of star-forming clouds."

Both environments involve atoms colliding, sticking together, and forming dust grains. But exactly how dust grains form and grow depends on many different factors. Nuth and his collaborator, Yuki Kimura of Hokkaido University in Japan, designed DUST-2 to study which factors are most important.

The refrigerator-sized mini-laboratory will launch aboard a Black Brant IX sounding rocket, reaching an altitude of about 210 miles high before beginning to fall back down to Earth. A lot happens in the next six and a half minutes. Thirty seconds into freefall, the first of its six experiments – all slight modifications of one another – kicks on. Inside a sealed chamber, a tiny filament begins to heat up. The thin coating of iron, silicon, magnesium and other particles sprayed onto the filament diffuse into the surrounding chamber. Some of these atoms will collide and stick – the beginnings of a dust grain – while others ricochet away. Each minute, another chamber turns on until the payload parachutes back to Earth for recovery.

Back in the lab, Nuth, Kimura and their teams will study the grains that formed in each of the six chambers. Hotter particles collide more often, so they will measure how grains formed differently farther or closer to the hot filament. Some elements may block one another from growing dust grains, so they will study which elements ended up in each grain. They'll also explore a surprise finding from the DUST-1 mission: In that experiment, dust grains that formed in argon gas with a small fraction (5%) of oxygen tended to smush together more than those formed in pure argon, a non-reactive noble gas.

"Without the oxygen, the atoms were like little billiard balls that touched and stuck," said Nuth. "But with oxygen, when the billiard balls touched, they partially merged together. That was something we didn't suspect."

Their hunch is that oxygen lowered the melting point of the dust grain, so that incoming particles mashed into partly molten material. To test this idea, DUST-2 removed all oxygen and replaced it with a small quantity (about 5%) of hydrogen.
"If that's the case, we should get none of that merging with hydrogen," Nuth said. "So we'll see if it pans out."

The experiment also includes a new carbon fiber heating filament for more precise control of the temperature. But the biggest difference between DUST-1 and DUST-2 is in mission operations – it's the first sounding rocket to launch during the COVID-19 pandemic. The team has implemented many new processes in the background to ensure the launch can happen while protecting the health of the workforce.
"As we carefully evaluated each task, we developed new ways to accomplish some of our hands-on work to minimize the risk of exposure," said John Hickman, deputy program manager for NASA's Sounding Rockets Program.

Every four hours, the team sanitizes all surfaces and equipment. "In addition to masks we have eye protection – face shields and safety glasses," said Eric Roper, NSROC mission manager who oversaw operations at White Sands. "We've worked pretty hard to develop a culture of doing these things as second nature."

It seems to be working – even with the new precautions, launch preparations have proceeded on schedule.

"Honestly it's going about the same pace as usual," said Roper. "The team's done a phenomenal job adapting to the situation."

NASA's Sounding Rockets Program is managed at the agency's Wallops Flight Facility, which is managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland. NASA's Heliophysics Division funds the Sounding Rockets Program for the agency.
