The smallest spacecraft in orbit As I type this, there a satellite sitting on the desk in front of me.

but next month, 100 miniature satellites like this one will be blasted into orbit. The Kicksat project is run by Zac Manchester

Once in orbit, the Falcon 9 will release the Dragon towards the ISS and, a few minutes later, pop the Kicksat mothership into orbit.

The slight delay is to avoid a space debris disaster like the movie Gravity. It be a risk

if 100 tiny satellites end up pinging around the world at high speed in exactly the same orbit as the space station.

The mothership will spend at least seven days in orbit before the sprites themselves are released. here are some space debris mitigation concerns

Hybrid Engines Make Runway-To-Orbit Missions A Reality A disembodied jet engine attached to a hulking air vent sits in an outdoor test facility at the Culham Science Center in Oxfordshire England.

The quest for a single-stage-to-orbit spaceship or SSTO has bedeviled aerospace engineers for decades. Bond's own exploration of the topic began in the early 1980s

because we felt it was better to focus our efforts on other less costly ways to get payloads to orbit says Dan Dumbacher NASA's deputy associate administrator for exploration systems development who spent two years working on the X-33.

But for routine missions to the ISS or to park a small observational satellite in orbit affordability becomes a critical consideration.

Each pound you put into orbit requires about 10 pounds or so of fuel to get it there says NASA's Dumbacher.

and hold enough hydrogen fuel to carry itself and about 16.5 tons of payload about the same capacity as most operational rockets into orbit.
