From robotic Martian explorers to the next generation of deep space observatories
In short: NASA’s reach extends from the frozen cracks of Antarctica to the far reaches of our solar system. While robotic pioneers study the history of Mars, new telescopes are being prepared to unlock the secrets of dark energy and the distant cosmos.
NASA's current operations span diverse planetary frontiers. In Antarctica, the Operation IceBridge mission returned to the Pine Island Glacier twice in 2012. Glaciologists, including Kelly Brunt, have been monitoring a massive glacial crack at this site, which possesses the potential to release an iceberg comparable in scale to New York City.
On the Red Planet, Mars remains a primary focus for robotic exploration. As the fourth planet from the Sun, Mars is currently inhabited entirely by machines. Rovers like Curiosity, which landed in August 2012, and Perseverance, which landed in February 2021, are working roughly 2,300 miles apart. Together, they are investigating whether the planet was once warmer, wetter, and capable of supporting microbial life.
The agency's ambitions also extend into deep space via advanced instrumentation. The Nancy Grace Roman Space Telescope is being developed as a next-generation observatory to investigate infrared astrophysics, exoplanets, and dark energy. This telescope will feature a 2.4-meter primary mirror and a Wide Field Instrument. This instrument is designed to provide a field of view significantly larger than the infrared capabilities of the Hubble Space Telescope, allowing for much more efficient sky coverage.
Even spacecraft in transit play a role in larger scientific goals. During a flyby on May 15, the Psyche spacecraft utilized Mars' gravity to adjust its trajectory and increase speed. This maneuver was a critical step in its journey toward the metal-rich asteroid Psyche, which it is scheduled to reach in 2029.
