Washington: A group of Indian students is part of 80 teams that will participate in the US space agency’s “Human Exploration Rover Challenge” to help NASA realise its goals for future exploration to Mars and beyond.

Nearly 80 teams from the US, India, Italy, Germany, Mexico, Colombia, Russia and Puerto Rico will compete in NASA’s annual challenge to be held at the US Space and Rocket Centre in Huntsville, Alabama on April 8 and 9.

The rover challenge requires student teams to design, construct, test and race human-powered rovers through an obstacle course that simulates the terrain potentially found on distant planets, asteroids or moons.

Teams race to finish the three-quarter-mile-long obstacle course in the fastest time, vying for prizes in various divisions, NASA said in a statement.

This year’s event incorporates two new and important changes. Teams are required to design and fabricate their own wheels.

Any component contacting the course surface for traction and mobility, including, but not limited to wheels, tracks, treads or belts cannot be purchased or considered an off-the-shelf product.

The second new feature is an optional “Sample Return challenge”.

Teams competing in this separate competition will collect four samples — liquid, small pebbles, large rocks and soil samples — using a mechanical arm or grabber they design and build.

The event will conclude with a ceremony at the Davidson Centre for Space Exploration in Huntsville where the awards will be presented for best design, rookie team, pit crew award and other accomplishments.

Inspired by the lunar roving vehicles of the Apollo moon missions, the competition challenges students to solve engineering problems, while highlighting NASA’s commitment to inspiring new generations of scientists, engineers and explorers. (IANS)

NASA’s Probe Discovers Signs Of Water on Asteroid Bennu

OSIRIS-REx will pass later this month just 1.2 miles (1.9 km) from Bennu, entering the asteroid's gravitational pull and analyzing its terrain.

NASA’s OSIRIS-REx spacecraft has discovered ingredients for water on a relatively nearby skyscraper-sized asteroid, a rocky acorn-shaped object that may hold clues to the origins of life on Earth, scientists said on Monday.

OSIRIS-REx, which flew last week within a scant 12 miles (19 km) of the asteroid Bennu some 1.4 million miles (2.25 million km) from Earth, found traces of hydrogen and oxygen molecules — part of the recipe for water and thus the potential for life — embedded in the asteroid’s rocky surface.

The probe, on a mission to return samples from the asteroid to Earth for study, was launched in 2016. Bennu, roughly a third of a mile wide (500 meters), orbits the sun at roughly the same distance as Earth. There is concern among scientists about the possibility of Bennu impacting Earth late in the 22nd century.

“We have found the water-rich minerals from the early solar system, which is exactly the kind of sample we were going out there to find and ultimately bring back to Earth,” University of Arizona planetary scientist Dante Lauretta, the OSIRIS-REx mission’s principal investigator, said in a telephone interview.

Asteroids are among the leftover debris from the solar system’s formation some 4.5 billion years ago. Scientists believe asteroids and comets crashing into early Earth may have delivered organic compounds and water that seeded the planet for life, and atomic-level analysis of samples from Bennu could provide key evidence to support that hypothesis.

“When samples of this material are returned by the mission to Earth in 2023, scientists will receive a treasure trove of new information about the history and evolution of our solar system,” Amy Simon, a scientist at NASA’s Goddard Space Flight Center in Maryland, said in a statement.

“We’re really trying to understand the role that these carbon-rich asteroids played in delivering water to the early Earth and making it habitable,” Lauretta added.

OSIRIS-REx will pass later this month just 1.2 miles (1.9 km) from Bennu, entering the asteroid’s gravitational pull and analyzing its terrain. From there, the spacecraft will begin to gradually tighten its orbit around the asteroid, spiraling to within just 6 feet (2 meters) of its surface so its robot arm can snatch a sample of Bennu by July 2020.

The spacecraft will later fly back to Earth, jettisoning a capsule bearing the asteroid specimen for a parachute descent in the Utah desert in September 2023. (VOA)
