NASA Launches Twin Mars Probes to Uncover How the Red Planet Lost Its Atmosphere

/in /tarafından

NASA is preparing to send two identical probes to Mars in a groundbreaking effort to uncover how the Red Planet lost its atmosphere — and what that might mean for Earth’s future.

Billions of years ago, Mars had a thick atmosphere, liquid water, and Earth-like chemistry. But today, it’s a frozen, airless desert. The question scientists are asking is simple yet profound: what went wrong?

The ESCAPADE mission — short for Escape and Plasma Acceleration and Dynamics Explorers — will send twin satellites, nicknamed Gold and Blue, to orbit Mars in formation, offering the first-ever 3D view of its magnetic and atmospheric interactions.

The probes, each about the size of a mini-fridge, are scheduled to launch Sunday from Kennedy Space Center aboard Blue Origin’s New Glenn rocket, which will make only its second flight. Instead of the usual direct trajectory, ESCAPADE will take a unique route — looping around a Lagrange point for a year before slingshotting toward Mars, a maneuver that could revolutionize future interplanetary mission planning.

NASA and the University of California, Berkeley’s Space Sciences Laboratory designed the mission to explore how solar wind — the stream of charged particles from the Sun — has stripped away Mars’ atmosphere over time. Without a strong magnetic field like Earth’s, Mars was left vulnerable to this cosmic erosion.

By 2027, the orbiters will study how solar storms affect Mars’ magnetosphere in real time, helping researchers understand both planetary climate loss and how to protect future astronauts from harmful space radiation.

“This is a low-cost mission — about $70 to $80 million — but with enormous scientific value,” said Casey Dreier of the Planetary Society. “Understanding Mars’ atmospheric loss helps us grasp how delicate Earth’s own system really is.”

As NASA faces tightening budgets, ESCAPADE represents a new model: small, efficient missions tackling big scientific questions — and a reminder that studying Mars may teach us more about saving Earth than we expect.

Researchers Discover Strange ‘Failed Star’ Planet Orbiting Double Star System in the Milky Way

Astronomers Discover Rare Polar-Orbiting Planet in Unusual Double-Brown-Dwarf System

Astronomers have uncovered an extraordinary planet in the Milky Way, orbiting in an unusual way around two failing stars. Unlike most exoplanets, this planet orbits over and under the poles of its parent stars, rather than following the plane of their orbits. Prior to this discovery, only sixteen exoplanets were known to orbit binary star systems, all of which moved in the plane of the stars’ mutual orbits. The discovery of a planet following a polar orbit in such a system has captured the attention of the scientific community, adding a new layer of intrigue to the study of planetary formation.

The two brown dwarfs that the planet orbits had already been identified by astronomers in 2018, using the SPECULOOS Southern Observatory in Chile. Brown dwarfs, often referred to as “failed stars,” are celestial objects that do not possess enough mass to ignite nuclear fusion in their cores. When the researchers turned their attention to the pair using the Very Large Telescope in Chile, they realized that these brown dwarfs, while not full-fledged stars, could still host fascinating systems.

This discovery marks the first time a “polar planet” has been observed orbiting a pair of brown dwarfs. These bodies, which are too small to sustain nuclear fusion, remain a subject of fascination because of their unique characteristics. The planet, designated 2M1510 (AB) b, is the first known exoplanet in such a system, providing solid evidence that fully formed planetary systems can exist around these “failed stars.” The fact that a binary brown dwarf system could support a planet in such an unusual orbit is a breakthrough in our understanding of stellar and planetary formation.

In addition to being a polar-orbiting planet, the system is also only the second pair of eclipsing brown dwarfs ever discovered, where one brown dwarf eclipses the other from Earth’s viewpoint. This rare configuration makes the discovery even more significant. As Amaury Triaud of the University of Birmingham points out, “A planet orbiting not just a binary, but a binary brown dwarf, as well as being on a polar orbit, is rather incredible and exciting.” The discovery was an unexpected bonus, as the team was not originally aiming to find such a system, underscoring the serendipitous nature of astronomical research.

Perseverance Rover Uncovers Abundant Unique Rock Samples Along Jezero Crater’s Rim

Perseverance Rover Discovers Rich Variety of Ancient Rocks at Jezero Crater’s Edge

NASA’s Perseverance rover continues to make remarkable discoveries as it explores the rugged terrain along the rim of Jezero Crater. Over the past few months, the rover has collected five core samples, closely examined seven rocks, and remotely analyzed 83 others using its onboard laser technology. Scientists have been surprised by the sheer diversity of rocks encountered — a mix of once-molten fragments, buried boulders, and well-preserved layered formations. The first rock sample from the crater rim, nicknamed “Silver Mountain,” was retrieved from an area called “Shallow Bay” and is thought to date back nearly 3.9 billion years.

The mission’s findings offer compelling clues about Mars’ distant past, especially its potential for once harboring water. In collaboration with the European Space Agency, NASA’s Mars Sample Return Program aims to bring sealed Martian samples back to Earth for more detailed examination. Among the highlights is the discovery of igneous rocks containing minerals that crystallized from ancient magma, possibly buried deep in Mars’ crust and later exposed by massive impacts. These findings could shed light on the planet’s early geological evolution and the processes that shaped its surface.

Currently, Perseverance is navigating the stratified landscape of Witch Hazel Hill, located near the crater’s western rim. Scientists believe the layers of rock here could record environmental changes that occurred when Jezero Crater likely held a vast, long-lost lake. The data being collected will help build a clearer timeline of Mars’ ancient climate and the possible presence of conditions favorable for life. The rover’s detailed study of rock textures, compositions, and layering is crucial for piecing together the story of water on early Mars.

Adding to the intrigue, Perseverance recently analyzed a boulder rich in serpentine minerals — a type of rock that, under specific conditions, can produce hydrogen gas, a potential energy source for microbial life. Discoveries like these boost hopes that traces of ancient life, if they ever existed, might be hidden within these ancient rocks. As the rover continues its trek along Jezero’s rim, mission scientists are carefully selecting the next promising sites for sample collection, inching closer to solving Mars’ long-standing mysteries.
