Printing the next generation of rocket engines

by —

For the last several years, aerospace companies have been examining ways to use additive manufacturing, or 3D printing, to aid the production of rocket engines.

Why Intelsat’s going with life extension over refueling

by —

Intelsat-901, a 17-year-old communications satellite running low on propellant, is awaiting a first-of-its-kind service call from a robotic spacecraft carrying a fresh tank of fuel.

Op-ed | We’ll need more than Trump’s Space Policy Directive to fix commercial remote-sensing regulations

by —

At the rate the commercial sector is innovating, regulatory practices will need to be agile, evolving quickly while still providing needed order and protections.

Op-ed | Regulatory reform is not a one-off event

by and —

The American Space Commerce Free Enterprise Act takes a number of important steps to provide regulatory certainty for emerging commercial space applications; and to implement the United States’ international obligation to provide authorization and supervision for its private sector actors.

Op-ed | Time to clear the air about launch pollution

by and —

Combustion emissions from launch vehicles present the space industry with a concern comparable to orbital debris that we can begin to address now, before it grows and becomes a potential impediment to space access.

In the wake of Northrop-Orbital merger, Aerojet’s solid rocket engine business teetering on the brink

by —

There are now technically two companies that still manufacture large solid rockets for military ICBMs. The industry is poised to become a monopoly, however, as Aerojet’s large solid rocket motor business is on not-so-solid ground.
