The long-awaited mission that could transform our understanding of Mars

A next-generation instrument on a delayed Martian rover may be the key to answering the question of life on the Red Planet

The Long-Awaited Mission That Could Transform Our Understanding of Mars

March 17, 2022, was a rough day for Jorge Vago. A planetary physicist, Vago heads science for part of the European Space Agency’s ExoMars program. His team was mere months from launching Europe’s first Mars rover — a goal they had been working toward for nearly two decades. But on

Space rocks and asteroid dust are pricey, but these aren’t the most expensive materials used in science

Space and Asteroid dust

After a journey of seven years and nearly 4 billion miles, NASA’s OSIRIS-REx spacecraft landed gently in the Utah desert on the morning of Sept. 24, 2023, with a precious payload. The spacecraft brought back a sample from the asteroid Bennu. Roughly half a pound of material collected from the

Asteroids in the solar system could contain undiscovered, superheavy elements

Asteroids in Space

For centuries, the quest for new elements was a driving force in many scientific disciplines. Understanding an atom’s structure and the development of nuclear science allowed scientists to accomplish the old goal of alchemists – turning one element into another. Over the past few decades, scientists in the United States,

How do astronomers know the age of the planets and stars?

Astronomers can estimate ages for stars outside the Solar System, but not planets

Measuring the ages of planets and stars helps scientists understand when they formed and how they change – and, in the case of planets, if life has had time to have evolved on them. Unfortunately, age is hard to measure for objects in space. Stars like the Sun maintain the same brightness,

Chandrayaan-3’s measurements of sulfur open the doors for lunar science and exploration

In an exciting milestone for lunar scientists around the globe, India’s Chandrayaan-3 lander touched down 375 miles (600 km) from the south pole of the Moon on Aug. 23, 2023. In just under 14 Earth days, Chandrayaan-3 provided scientists with valuable new data and further inspiration to explore the Moon. And the Indian Space Research Organization has shared these initial results with

There’s no question that sending human beings to space is an extraordinarily difficult and perilous proposition. Since human space exploration began just over 60 years ago, 20 people have died – 14 in the NASA space shuttle tragedies of 1986 and 2003, three cosmonauts during the 1971 Soyuz 11 mission,
