The Microlaunch Space Race Has Begun

Astronomy Magazine - Wed, 08/08/2018 - 04:00
In the vastness of space, unfathomable size is generally the norm. But when Jordi Puig-Suari, an aerospace engineering professor, began looking at the stars, he started thinking small. Together with Bob Twiggs, a professor at Stanford University, they developed the CubeSat, a tissue box-sized satellite that has intensified interest in space and revolutionized satellite communication. When Puig-Suari worked at California Polytechnic State University in 1999, he was unimpressed with the typical si

What does a meteor sound like?

Astronomy Magazine - Wed, 08/08/2018 - 04:00
When a meteor screams through our upper atmosphere, it’s a silent show for us here on the ground. Most meteors burn up dozens of miles above the surface, and even if a sonic boom reaches us it comes minutes after the visual spectacle. However, reports of meteors have for years been accompanied by reports of strange sizzling sounds filling the air, as if someone was frying bacon. Sound travels too slowly for the meteor to be directly responsible for the phenomenon, so such reports are usua

First interplanetary CubeSat mission, MarCO, is only the beginning

Astronomy Magazine - Tue, 08/07/2018 - 04:00
When the InSight lander began its journey to Mars on May 5th, two tiny satellites tagged along for the ride — CubeSats called MarCO-A and MarCO-B. CubeSats are a small and relatively inexpensive type of spacecraft, and they tend to use off-the shelf technologies. In recent years, dozens of them have been launched into low-Earth orbit by scientists, students, and businesses alike. The MarCOs, however, are the first CubeSats to travel into deep space, and they could pave the way for a new g
