Why a key NASA telescope is at the centre of a LGBT debate?.
NASA is set to launch the large infrared James Webb Space Telescope (JWST) touted as the “premier observatory” of the coming decade later this year. Considered the successor of the Hubble Space Telescope, JWST will study various phases in the history of the universe, from the formation of solar systems to the evolution of our own Solar System.
But before it launches, NASA has an important decision to make — whether to rename the $8.8-billion telescope. These considerations stem from allegations that NASA’s former government-appointed administrator James Webb, after whom JWST is named, had persecuted homosexuals when he had worked for the government.
According to an article published in the journal Nature, NASA does not have a shortlist of names as of now. Bill Nelson, the NASA administrator who is likely to make the final decision, has not said anything on this publicly.
In May, four prominent astronomers —Chanda Prescod-Weinstein, Sarah Tuttle, Lucianne Walkowicz and Brian Nord — launched the petition for a change in name. They had already made their case with an article in Scientific American in March, writing that it was “unfortunate” that “NASA’s current plan is to launch this incredible instrument into space carrying the name of a man whose legacy at best is complicated and at worst reflects complicity in homophobic discrimination in the federal government”.
They wrote that Webb (1906-92) purged LGBT individuals from the workforce after he arrived at NASA in 1961 (he served until 1968). This was then federal policy, “which was a forerunner to the antigay witch hunt known today as the lavender scare”, according to the astronomers, who have written that Webb was aware of this as early as 1950.
In 2016, archivist Judith Adkins wrote that as part of “Lavender Scare” thousands of gay employees were fired or forced to resign from the federal workforce because of their sexuality. It was during this time that Webb started his career with the US government in the late 1940s, prior to joining NASA. When Webb was administrator, NASA launched over 75 space science missions, including probes that were sent to Mars and Venus.
As per NASA, Webb “did more for science than perhaps any other government official and… it is only fitting that the Next Generation Space Telescope would be named after him”.
Not all astronomers seem to agree with the four who have started the petition. It has triggered a debate, nevertheless. Those not in favour of renaming believe that either there is not enough evidence to implicate Webb, or that the window to do so has passed.
The debate marks a rare instance of astronomers making a political statement. Another recent example is from ornithology in the US, where some scientists have sought the renaming of birds named after people linked to racism, slavery and White supremacy. Here, too, ornithologists are divided, because some of them believe that changing names of birds would lead to confusion, and that it is akin to erasing an important part of history.
James Webb Space Telescope (JWST)
- It is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity.
- Webb was formerly known as the "Next Generation Space Telescope" (NGST) and it was renamed in 2002 after a former NASA administrator, James Webb.
- It will be a large infrared telescope with an approximately 6.5 meter primary mirror which will be launched on an Ariane 5 rocket from French Guiana in 2021.
- It is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
- The longer wavelengths enable Webb to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies.
- It will be the premier space observatory for astronomers worldwide, extending the tantalizing discoveries of the Hubble Space Telescope.
- It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems.
- Webb will observe primarily in the infrared and will have four science instruments to capture images and spectra of astronomical objects.
- The instruments on Hubble can observe a small portion of the infrared spectrum from 0.8 to 2.5 microns, but its primary capabilities are in the ultra-violet and visible parts of the spectrum from 0.1 to 0.8 microns.
- Webb will have an approximately 6.5 meter diameter primary mirror, which would give it a significantly larger collecting area than the mirrors available on the current generation of space telescopes.
- Hubble's mirror is a much smaller 2.4 meters in diameter and its corresponding collecting area is 4.5 meter square, giving Webb around 6.25 times more collecting area.
- The Hubble Space Telescope orbits around the Earth at an altitude of ~570 km above it.
- Webb will not actually orbit the Earth, instead it will sit at the Earth-Sun L2 Lagrange point, 1.5 million km away.
- At the L2 point Webb's solar shield will block the light from the Sun, Earth, and Moon which will help Webb stay cool, which is very important for an infrared telescope.
Hubble Space Telescope
- It is named in honor of the trailblazing astronomer Edwin Hubble.
- It is a large, space-based observatory, which has revolutionized astronomy since its launch and deployment by the space shuttle Discovery in 1990.
- It has been used to observe some of the most distant stars and galaxies yet seen, as well as the planets in our solar system.
- It is the first major optical telescope to be placed in space, the ultimate mountaintop.
