Balloon-Borne SuperBIT Telescope Releases 1st Research Images

The Tarantula nebula appears as a vivid burst of pink, red and gold in the center of the black, star-dusted background of space. The nebula is intensely colored near the center of the image, fading to dusty clouds of dark red and purple toward the edges. The entire nebula has the appearance of a bright cloud of glowing dust. Many stars are visible in the background, including shining through the nebula.

The Super Pressure Balloon Imaging Telescope (SuperBIT) that launched on a scientific super pressure balloon April 16, 2023, local time from Wānaka, New Zealand, captured its first research images from this flight of the Tarantula Nebula and Antennae Galaxies. These images were captured on a balloon-borne telescope floating at 108,000 feet above Earth’s surface, allowing scientists to view these scientific targets from a balloon platform in a near-space environment.

The advantage of balloon-based versus space telescopes is the reduced cost of not having to launch a large telescope on a rocket. A super pressure balloon can circumnavigate the globe for up to 100 days to gather scientific data. The balloon also floats at an altitude above most of the Earth’s atmosphere, making it suitable for many astronomical observations.

The SuperBIT telescope captures images of galaxies in the visible-to-near ultraviolet light spectrum, which is within the Hubble Space Telescope’s capabilities, but with a wider field of view. The goal of the mission is to map dark matter around galaxy clusters by measuring the way these massive objects warp the space around them, also called “weak gravitational lensing.”

The Antennae Galaxies as seen by SuperBIT. The nebula is a slightly transparent, light blue mass in the middle of the image. The mass is divided into two lobes, shaped like teardrops. The upper lobe has a spiral of light blue and yellow in its center. Extending straight up and down from the two lobes are two thin tails of gas and dust, which look like antenna. The nebula is on the backdrop of black space, dotted with white and blue stars. The largest stars, one in the upper right and one in the lower left, each have four diffraction spikes.

The Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region’s bright, newly formed stars. The Tarantula Nebula has previously be captured by both the Hubble Space Telescope and James Webb Space Telescope.

The Antennae galaxies, cataloged as NGC 4038 and NGC 4039, are two large galaxies colliding 60 million light-years away toward the southerly constellation Corvus. The galaxies have previously been captured by the Hubble Space Telescope, Chandra X-ray Observatory, and now-retired Spitzer Space Telescope. A composite image of the galaxies combines data taken by all three telescopes.

SuperBIT’s first research images from this flight were released by Durham University here. The SuperBIT team is a collaboration among NASA; Durham University, United Kingdom; the University of Toronto, Canada; and Princeton University in New Jersey.

First Super Pressure Balloon for 2023 Campaign Lifts Off from New Zealand

NASA’s Scientific Balloon Program successfully launched its football-stadium-sized, heavy-lift super pressure balloon (SPB) from Wānaka Airport, New Zealand, at 11:42 a.m., Sunday, April 16 (7:42 p.m.. April 15 in U.S. Eastern Time), on a mission planned for 100 or more days. Over the next couple hours, the balloon will begin to fully inflate as it floats up to an altitude of 110,000 feet.

NASA Schedules First Super Pressure Balloon Launch Attempt

WĀNAKA, New Zealand — NASA is targeting Sunday, April 16 (Saturday, April 15 in the United States), to conduct a super pressure balloon (SPB) test flight launching from Wānaka Airport, New Zealand, to further test and qualify the technology, which can offer cost savings compared to space missions. This first launch will also carry the Super Pressure Balloon Imaging Telescope (SuperBIT), from Princeton University.

“We are excited to be back in Wānaka for two planned balloon missions set to qualify this game-changing technology that enables long-duration flight in a near-space environment for the science community,” said Debbie Fairbrother, NASA’s Balloon Program Office chief. “A lot of different weather factors need to line up to support a launch attempt, and so far, Mother Nature is cooperating with us nicely for this first opportunity.”

NASA will begin flight preparations in the early morning hours Sunday and will continue to evaluate real-time and forecast weather conditions throughout the morning.  If weather is conducive for launch, lift-off is scheduled between 8 and 11:30 a.m. locally in New Zealand (between 4 and 7:30 p.m. U.S. EDT Saturday, April 15).
 
This is the first scheduled launch attempt for NASA’s 2023 Wānaka Balloon Campaign. The window for the campaign opened April 3, but weather conditions haven’t lined up until now.
 
For those in the local area, the public won’t be allowed at Wānaka Airport on the morning of the launch attempt or to park alongside the airport. However, immediately after lift-off, the balloon will be visible for miles around – the best viewing points will be on the hill on the Hawea side of the Red Bridge by Kane Road or on the Hawea Flat side of the Clutha River.
 
In addition, the launch can be tracked in the following ways:

Track the progress of the flight at the following link, which includes a map showing the balloon’s real-time location, at: http://www.csbf.nasa.gov/newzealand/wanaka.htm

For subsequent launch attempts, if needed, NASA will announce by 2 p.m. NZST (10 p.m. EDT) if the next day’s forecast weather will support a launch attempt.

For launch, winds need to be light and flowing in a reliable direction both at the surface and at low levels up to about 1,000 feet (300 meters). Winds flowing in opposite directions on the ground and lower levels could have a shearing effect on the balloon. In addition, NASA monitors for favorable stratospheric wind conditions at 110,000 feet (33.5 km), which is where the balloon will float.

After launch the 18.8-million-cubic-foot (532,000 cubic-meter) SPB will ascend to its float altitude where the stratospheric winds will propel it at speeds up to and exceeding 100 knots on a weeks-long journey around the southern hemisphere.

The launch window is now open for NASA’s 2023 New Zealand Super Pressure Balloon (SPB) launch campaign aimed to further test and qualify NASA’s SPB technology, which can offer cost savings compared to space missions.

Pictured here, technicians work on the SuperBIT payload and test out the different support and communications systems on the gondola during a hang compatibility test April 3, 2023, at the agency’s scientific balloon launch site in Wānaka, New Zealand.

Two SPB launches are scheduled from Wānaka this year, and on each balloon, NASA will fly science payloads as missions of opportunity. The balloons may be visible from the ground during their flights, which are planned for up to 100 days or more. For more information, see this story.

The team is evaluating weather daily for potential launch opportunities. NASA will announce by 2 p.m. NZST (10 p.m. ET) if the next day’s forecast weather will support a launch attempt.

For launch, winds need to be light and flowing in a reliable direction both at the surface and at low levels up to about 1,000 feet (300 meters).

Technicians from NASA’s Scientific Balloon Program recently performed weight test procedures of the Super Pressure Balloon Imaging Telescope (SuperBIT) payload in advance of planned super pressure balloon flight operations from Wanaka, New Zealand, in 2023.

SuperBIT will use a wide field of view to image large galaxy clusters from a balloon platform in a near-space environment. By measuring the way these massive objects warp the space around them, also called “weak gravitational lensing,” SuperBIT will be able to map the dark matter present in these clusters.
