It provides thrust to a spacecraft by bouncing microwaves around in a closed container. Solar energy provides the electricity to power the microwaves,
say their research could help develop new types of heat shields on spacecraft or be used in gas turbines.
so their uses are restricted to very specialized applications, such as spacecraft or advanced cooling systems. The new foam metal being developed by the NC State team led by Afsaneh Rabiei,
which the company says could boost computing power of verything from smartphones to spacecraft. he company unveiled the industry first seven-nanometer chip that could hold more than 20 billion tiny switches or transistors for improved computing power.
The JPL team responsible for Onsight specializes in systems to control robots and spacecraft. The tool will assist researchers in better understanding the environment
"This work means there's an opportunity to use composite metal foam to develop safer systems for transporting nuclear waste, more efficient designs for spacecraft and nuclear structures,
kicking off the robotic vehicle's clandestine fourth mission as well as the first flight of a tiny solar-sailing spacecraft.
and more on the gear the spacecraft is carrying to orbit. X-37b Space Plane's 4th Mystery Mission in Photos"We are excited about our fourth X-37b mission,"Randy Walden,
The Air force owns two X-37b spacecraft, both of which were built by Boeing's Phantom Works division.
saying the X-37b is simply testing out technologies for reusable vehicles and future spacecraft.
it generates thrust by accelerating ions (electrically charged atoms or molecules) out the back of a spacecraft.
plus it enhances spacecraft operational flexibility, survivability and longevity.""The NASA payload, called the Materials Exposure
The goal is to gather data that could aid in the design of future spacecraft,
the Planetary Society's Lightsail spacecraft will come back down to Earth in just a few weeks.
But the shiny sail should make the bantam spacecraft visible to the naked eye during its brief orbital trial.
#New Spaceship Antenna Prevents Radio Silence During Fiery Re-Entry When future spacecraft re-enter the atmosphere,
a new kind of antenna might help them keep in contact with ground control, despite the fiery sheaths of superhot plasma around them, researchers say.
As the crippled spacecraft plummeted back toward Earth, the communications blackout lasted more than a minute longer than expected,
The discovery means the materials could be useful in spacecraft, the nuclear industry and in medicine.
in protecting equipment onboard exploratory spacecraft from the high radiation fluxes sometimes found in space without adding significantly to their weight,
