Researchers are developing a new type of rocket propellant made of a frozen mixture of water and “nanoscale aluminum” powder that is more environmentally friendly than conventional propellants and could be manufactured on the moon, Mars and other water-bearing bodies.
NASA in my opinion has begun to lag behind in recent years and in some ways perhaps regressed technologically. Whether this is due to political pressure or financial concerns the end result is the same: an organization that has become resistant to new approaches and ideas presented by the latest generation of engineers. As of yet it remains unclear how NASA will progress regardless of their funding situation. Will they continue with business as usual that has even the most ardent space exploring supporters bemused or will they realize working cooperatively with private entrepreneurs in developing commercial space flight?
