Fourth of July Holidays in Space

Sixty years ago, to welcome NASA’s Manned Spacecraft Center (MSC), now Johnson Space Center (JSC), the city of Houston threw a Texas-size Fourth of July celebration. The seven Mercury astronauts featured prominently in that Independence Day celebration in July 1962. Astronauts didn’t…

India launches 3 satellites and an experimental orbiting platform

An Indian rocket launched three satellites and an experimental orbiting platform on Thursday morning (June 30) in what has been its 55th launch. The four-stage, 145.7-foot-tall (44.4 meters) Polar Satellite Launch Vehicle (PSLV) lifted off from Satish Dhawan Space Centre in southeastern India on Thursday at 8:33 a.m. EDT (1233 GMT; 6:03 p.m. local time) into the clear blue sky in what was described as “a marvelous liftoff” by the mission commentator. The rocket’s stages separated faultlessly as planned with payload separation commencing at 8:53 a.m. EDT (1253 GMT). “PSLV C…

Swarms of tiny robots may one day explore oceans on other worlds

NASA’s Jet Propulsion Laboratory has awarded $600,000 of additional funding towards a concept that would see swarms of diminutive swimming robots sent to explore oceans on moons or planets throughout the solar system. Such a system of distributed tiny robots could extend the reach of a mission sent to study oceans beneath the icy surfaces of some of our solar system’s moons such as Saturn’s Enceladus or Jupiter’s Europa. The concept, called “Sensing With Independent Micro-Swimmers,” or SWIM, is the brainchild of Ethan Schaler, a robotics mechanical engineer at NASA’s…

MoveShootMove Star Tracker review

Every astrophotographer knows the 500 rule. It’s a way of working out how long any exposure can last, at any given focal length, before the rotation of the planet you’re on gives itself away and the stars start to smear across the sky. In simple terms, you take your focal length in millimeters, divide it by 500, and that’s the longest theoretical exposure time the stars will stay sharp. So a 50mm lens gives you a very short maximum exposure time of 10 seconds. A 25mm lens doubles that, to…
