NASA wants you to design part of its future Venus rover

NASA is looking for help in designing a vital element of a rover that could one day explore Earth’s hellish twin, Venus. The component would allow the rover to safely explore the surface, and would have to be capable of enduring an incredibly hostile e… Continue reading NASA wants you to design part of its future Venus rover

NASA's TESS spots three new Earth-sized exoplanets orbiting nearby star

The three new planets discovered by TESS – L 98-59b, c and d – as compared ...

Three new, roughly Earth-sized exoplanets have been found orbiting a nearby star. Named L 98-59b, c and d, the small worlds were spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS), as part of a larger haul of data that finally brings the total tally past the milestone of 4,000 exoplanets discovered to date.

Explore Venus with a Strandbeest Rover

There’s a little problem with sending drones to Venus: it’s too hostile for electronics; the temperature averages 867 °F and the pressure at sea level is 90 atmospheres. The world duration record is 2 hours and 7 minutes, courtesy of Russia’s Venera 13 probe. To tackle the problem, JPL has created a concept for AREE, a mechanical robot designed to survive in that environment.

AREE consists of a Strandbeest configuration of multiple legs with a monster fan propelling it, and one can imagine it creeping over the Venusian landscape. While its propulsion system might be handled by the Strandbeest mechanism, …read more
