Cracker-sized satellites launch into orbit
Source: Phys.org
After years of planning and several last-minute delays, about 100 Cornell-developed mini satellites demonstrating space flight at its simplest have launched into orbit and are now circling Earth.
With just a laptop, antenna and a few other basics, space flight enthusiasts can listen for signals sent by the cracker-sized "sprites" that launched April 18 aboard a SpaceX Falcon 9 rocket as part of NASA's CRS-3 mission. Still inside their mothership craft, the sprites are scheduled to deploy on May 4 to become the smallest free-flying spacecraft.
The project is called KickSat and has been led by Zac Manchester '09, now a graduate student in aerospace engineering, since he was an undergraduate doing research with Mason Peck, associate professor of mechanical and aerospace engineering.

The sprites are housed inside a CubeSat, which is a small satellite frequently used in space research. The CubeSat is aboard a capsule that separates from the shuttle, which continues to the International Space Station. The KickSat CubeSat is second in line to deploy. (Other research missions are aboard.)

(40,416 posts)Are misinformed.
I have heard a bit about these.
First, they are in low orbit. Second, they have no propulsion to keep their orbits from degrading. Third, they will fairly quickly plunge to earth. Fourth, they are designed that way.
So people can sleep soundly.
I think they are very cool.

(40,416 posts)Those nano satellites do not last very long in low orbit where there are still traces of atmosphere. Otherwise, why would NASA let them be deployed?

(15,882 posts)I agree with you, good project. I was trying to think of what use, maybe getting a lot of readings over a hurricane that is moving, or a bunch targeting some land formation. It said they could transmit, but can they pick up data, or ?
But yeah. It's a lot cooler than me grinding up powder to make engines and shoot home made rockets when I was younger. On the other hand, that was a lot of fun

:satire:
Just kidding. I think these things are awesome. Even high school students are designing them! Fucking wonderful.

(11,361 posts)... cheese-sized satellites to meet up with them? If not this story is way too dry.
