The Golden Age of Space Exploration Is Here

For more than three decades, NASA's Hubble Space Telescope has transformed our understanding of the cosmos. More recently in 2021, NASA alongside ESA launched the James Webb Space Telescope which pushed deep into the universe's past. Yesterday on August 30th, NASA launched its new observatory, the Nancy Grace Roman Space Telescope, not to look deeper than Webb and Hubble, but to see vastly more of the universe in one go.

Yesterday, SpaceX's Falcon Heavy lifted off from the historic Launch Complex 39A, with the Nancy Grace Roman Space Telescope aboard. Its destination? Nearly one million miles away from home planet to a point named the "Sun-Earth L2 Lagrange Point" where the James Webb Space Telescope is currently occupying. Due to being place in the L2 region, the telescope will be on the opposite side of the Earth away from the sun. This gives the telescope shielding from thermal radiation and allows there to be no glare from the Sun or Earth. From here, Roman will conduct some of the largest and most detailed infrared surveys ever attempted.

In honor of Dr. Nancy Grace Roman, who was the first Chief of Astronomy at NASA and affectionately referred to as the "Mother of Hubble," the telescope symbolizes the future of astronomy from space. While the Roman has a primary mirror that is 2.4 meters wide like the one used in Hubble, the telescope's amazing Wide Field Instrument enables it to take pictures whose field of vision is 100 times wider. Unlike previous telescopes that could only look at a small area in the sky, Roman can observe very large sections of the sky at once.

Both telescopes will operate in tandem, with Roman scanning the universe for interesting targets and Webb performing closer examinations of them. This approach will ensure that scientists have an unparalleled level of both exploration and analysis. The observatory is also expected to create an unprecedented amount of scientific data.

According to NASA, the telescope will create several hundred terabytes of data annually while imagining some two billion galaxies. All that data will be made accessible to the public, making possible discoveries well beyond the intended scientific purpose of the telescope.

The search for other planets outside our solar system will not be complete without Roman.

By utilizing gravitational microlensing, it is predicted that thousands of new exoplanets will be found using the telescope, including planets different from those which we have ever seen before. The advanced technology on board the Roman Space Telescope, which includes its Coronagraph Instrument, can image a planet around a distant star by nullifying the intense light coming from it.

The mission's goal includes one of the biggest questions about the cosmos: why is the universe's expansion speeding up? Researchers are certain that the reason for this is dark energy but the exact cause of it remains a mystery to us. The Roman Space Telescope will be observing millions of galaxies and thousands of far-off supernovae, which will give us the most detailed map of the history of the expansion of the universe.

After lift-off, Falcon Heavy's two side boosters detached from the center core and landed at Landing Zone 2 and 40 at the Canaveral Space Force Station a few miles south of where they lifted off from, while the center core kept powering the flight until staging. The Trans-L2 injection occurred during the upper stage of the rocket's flight. After separating from the second stage, the spacecraft is on its 30-day trip to travel more than one million miles to reach the L2 Lagrange Point. While on the cruise to L2, Roman will extend its solar arrays, undergo some system tests, and carry out several trajectory correction burns using its own propulsion system. Upon arrival at the L2 point, Roman will begin making orbits around L2, which is a region of gravitational stability, where scientists will spend several months commissioning the telescope's instrumentation for its five-year prime science mission. The proven reliability of Falcon Heavy and its capability to send heavy cargo out of Earth's orbit made this launch system the perfect choice for one of NASA's most advanced telescopes.

Though Hubble uncovered the majesty of space, and Webb its early evolution, it is only with Roman that we will gain the wide-angle perspective necessary for comprehending structure, evolution, and mysteries yet undiscovered amongst the stars.
