KickSat: Our goal is to dramatically lower the cost of spaceflight, making it easy enough and affordable enough for anyone to explore space
Posted by Richard Christophr Saragoza in categories: biotech/medical, computing, solar power, space travel, sustainability
We can do this by shrinking the size and mass of the spacecraft, allowing many to be launched together.
The Sprite is a tiny (3.5 by 3.5 centimeter) single-board spacecraft. It has a microcontroller, radio, and solar cells and is capable of carrying single-chip sensors, such as thermometers, magnetometers, gyroscopes, and accelerometers. To lower costs, Sprites are designed to be deployed hundreds at a time in low Earth orbit and to simultaneously communicate with a ground station receiver.

What It’s Like Inside a Blue Origin Space Capsule
Posted by Genevieve Klien in category: space travel
Among science fiction stories with space flight, the overwhelming majority are about combat, both between spacecraft and between futuristic ground troops. Not to mention the occasional starship marine assault trying to board a hostile ship while in flight. Yes, there are a few non-combat stories, mostly about exploration, but space combat is here to stay.
This is just the natural continuation of the process of militarisation of space
Which naturally leads to questions about the space branch of the military of various nations. The “astro-military” in other words. Some may start out as a subdivision of an existing branch and eventually grow large enough to split off (such as how the US Army Air Corps spit off to become the US Air Force in 1947). Some may grow large enough to absorb other branches of the military, others may be reabsorbed into other branches. In William Keith’s Galactic Marines series one of the themes of the early novels is how the US Marines fight being absorbed or eliminated. Their solution is diversifying their mission to include performing assaults on Luna and Mars.

China rockets to forefront of global space race with sea launch success
Posted by Derick Lee in categories: engineering, space travel
The launch was expected to encounter many technical and engineering challenges, including simplified procedures for pre-launch testing, the rocking motion of the ship and heat dissipation in a confined space.
China has become the first nation to fully own and operate a floating launch platform for its space missions.

There’s a Hidden Spacecraft Dump Deep in The Ocean — Here’s What’s Down There
Posted by Genevieve Klien in category: space travel
The most remote location on Earth has many names: It’s called Point Nemo (Latin for ‘no one’) and the Oceanic Pole of Inaccessibility. Most precisely, its exact coordinates are 48 degrees 52.6 minutes south latitude and 123 degrees 23.6 minutes west longitude.
The spot is about 2,250 km (1,400 miles) from any spot of land — and the perfect place to dump dead or dying spacecraft, which is why it’s home to what NASA calls its “spacecraft cemetery.”
“It’s in the Pacific Ocean and is pretty much the farthest place from any human civilisation you can find,” NASA said.

Warp Drive May Be More Feasible Than Thought, Scientists Say
Posted by Quinn Sena in category: space travel
Faster than light travel may actually be possible using a warp drive to bend space around a starship. New calculations suggest such a vehicle would require less energy than once thought.

Using black holes to conquer space: The halo drive
Posted by Quinn Sena in categories: cosmology, space travel
The idea of traveling to another star system has been the dream of people long before the first rockets and astronauts were sent to space. But despite all the progress we have made since the beginning of the Space Age, interstellar travel remains just that – a dream. While theoretical concepts have been proposed, the issues of cost, travel time and fuel remain highly problematic.
A lot of hopes currently hinge on the use of directed energy and lightsails to push tiny spacecraft to relativistic speeds. But what if there was a way to make larger spacecraft fast enough to conduct interstellar voyages? According to Prof. David Kipping, the leader of Columbia University’s Cool Worlds lab, future spacecraft could rely on a halo drive, which uses the gravitational force of a black hole to reach incredible speeds.
