Whipple’s Shield protected Giotti
When the Giotti spacecraft launched on its voyage to explore Halley’s Comet in 1985, it was an invention by the son of an Iowa farmer decades earlier that allowed the mission to be successful. The most difficult problem of the mission to overcome was how to ensure that Giotto survived long enough to snap its …
NGC 6357: A cosmic ‘winter’ wonderland
Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the cloud that surrounds them. This composite image contains X-ray data from NASA’s Chandra X-ray Observatory and …
India lofts 104 satellites to set single-launch record
In a record-breaking flight, ISRO’s Polar Satellite Launch Vehicle (PSLV) successfully orbited the 714 kg Cartosat-2 Series satellite along with 103 co-passenger satellites on February 15 from the Satish Dhawan Space Centre in Sriharikota, India. PSLV-C37 lifted off at 9:28 am IST, as planned, from the First Launch Pad. After a flight of 16 minutes …
Why did Schiaparelli crash during landing?
Contact with the ExoMars Schiaparelli lander was lost during its attempt to make it to the surface last October. It was later discovered that the lander had crashed into the surface of the Red Planet. A large volume of data recovered from the Mars lander shows that the atmospheric entry and associated braking occurred exactly …
Skimming an alien atmosphere
After the smooth arrival of ESA’s latest Mars orbiter, mission controllers are now preparing it for the ultimate challenge: dipping into the Red Planet’s atmosphere to reach its final orbit. The ExoMars Trace Gas Orbiter is on a multiyear mission to understand the tiny amounts of methane and other gases in Mars’ atmosphere that could …
Nearest star has planet in habitable zone
Earth-mass world spotted in orbit around Proxima Centauri Astronomers using ESO telescopes and other facilities have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The long-sought world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist …

The town of Mars, Pennsylvania and NASA marked the Martian New Year with a three-day celebration in the small western Pennsylvania borough. As part of the celebration of the Red Planet’s latest complete journey around the Sun, the town hosted three days of Science, Technology, Engineering, Arts and Mathematics (STEAM) activities. This article appeared in the …
These robots are out of this world
It may have lacked the destructive mayhem of a BattleBots competition, but the 2015 Sample Return Robot Challenge also just may hold the key in furthering our space exploration goals. Sixteen teams competed in the event held last month at the Worcester Polytechnic Institute (WPI) in Worcester, Mass. Teams were required to demonstrate autonomous robots …
