Exploring the SuperBIT Telescope: A Revolutionary Leap in Astronomy

Written on

Chapter 1: The Future of Space Telescopes

For decades, the Hubble Space Telescope has been a remarkable tool for capturing breathtaking images of the universe, an achievement that other instruments find challenging to replicate. Its superior vantage point, situated high above Earth's atmospheric interference, is a key factor in its success. However, a collaborative initiative involving Durham University, Princeton University, and NASA is pioneering a more cost-effective method to position telescopes in similarly clear regions of the atmosphere. This innovative project is known as SuperBIT, which utilizes large balloons rather than traditional rocket launches.

As NASA finalizes the much-anticipated James Webb Space Telescope (JWST), it highlights the extensive engineering and reliability testing required for spacecraft. Once deployed in space, repairs become an arduous, if not impossible, task. Furthermore, the design must accommodate the constraints of rocket travel, withstand the extreme forces of launch, and function properly in the vacuum of space.

Section 1.1: SuperBIT's Innovative Approach

SuperBIT, or Superpressure Balloon-borne Imaging Telescope, aims to streamline this process by employing a massive helium-filled balloon to elevate a telescope into the upper atmosphere. This method is based on NASA's recent advancements in "superpressure" balloon technology, allowing them to maintain altitude for extended periods, sometimes months. The balloon’s dimensions are comparable to a football stadium, boasting a volume of 695,830 cubic yards (532,000 cubic meters), which provides sufficient lift to elevate a large parabolic mirror telescope to an impressive height of 25 miles (40 kilometers).

Generally, the boundary of space is considered to begin at approximately 50-60 miles (depending on the source), but at 25 miles, SuperBIT will be positioned near the stratosphere, where much of the atmospheric interference that degrades images from ground-based telescopes will be significantly reduced. The atmospheric pressure at this altitude is a mere 1 millibar, equivalent to about 0.0009 of Earth's standard atmospheric pressure.

Subsection 1.1.1: The Telescope's Specifications

A view of the SuperBIT telescope in action

The prototype of SuperBIT is equipped with a 0.5-meter telescope (illustrated above), but plans are already in motion to enhance it to a 1.5-meter version. With contemporary advancements in technology, the team is confident that this upgraded instrument could rival, or even surpass, the capabilities of Hubble. Notably, SuperBIT won't remain airborne indefinitely; it will return to the ground periodically as the balloon deflates, allowing ground teams to perform necessary maintenance and upgrades. There's even potential for incorporating a 2-meter reflector into SuperBIT, which would enhance light collection and resolution, making it a significant advancement over Hubble.

Section 1.2: Looking Ahead

The current objective is to prepare SuperBIT for its next launch in 2022, where it will focus on collecting data about dark matter, possibly shedding light on some recent anomalies observed in muon experiments.
