America’s New Rules for Drones Will
Keep Some Businesses Grounded (Source: Economist)
Like driverless cars, pilotless aircraft also promise to be a huge
business if regulatory obstacles can be overcome. This week, after
years of delay, America’s Federal Aviation Administration (FAA) came
out with its draft rules for commercial drones. Although not as
draconian as some had feared, unmanned aircraft will continue to have
their wings clipped.
There had been worries that the FAA would require drones to undergo an
expensive and lengthy process to be certified as airworthy, as happens
with manned aircraft; and that the person on the ground operating the
drone would need a pilot’s licence. Instead, the agency is proposing
that drones weighing less than 25kg (55lbs), that are well-maintained
and checked before flight, can be flown without certification by
operators who have passed a basic aeronautical test.
The drones, however, would have to stay below 500 feet, fly only in
daylight and remain in view of their operators at all time. And they
could not be flown over people. This is a “good first step”, said the
Association for Unmanned Vehicle Systems, a lobby group. It would
allow, say, an estate agent to take aerial photographs of a house being
put up for sale, or a farmer to survey a crop for signs of disease—and
do so for a lot less than hiring a helicopter. But not being allowed to
fly over crowds might prevent television companies from filming
sporting events with drones. (2/24)
Moon Space Law: Legal Debate Swirls

First, Congress needs to revisit the Commercial Space Launch Act and
amend it so that the FAA has broader authority between the launch and
re-entry phase of future commercial activities. The FAA and Congress
need to consider how potential laws like the proposed Asteroid Act will
affect the Commercial Space Launch Act and specifically how it will
affect international treaty obligations.
Second, the executive branch, specifically the State Department, will
need to work with the FAA and Congress to determine how future
commercial activities such as Bigelow's will affect not only
international treaty obligations but the geopolitical sphere as well.

Could Ionized Gas Do A Better Job of
Sterilizing Spacecraft? (Source: Astrobiology)
Earth’s microbes are a hardy bunch. They can survive in extreme
environments, such as inside hot springs at the bottom of the ocean.
Some have even remained alive despite being exposed to the ultraviolet
and ionizing radiation, extreme low temperatures, and vacuum of space.
This is why planetary protection advocates are so concerned about our
exploration of other planets in the Solar System.
Concerns about the contamination of the icy moon Europa, for example,
prompted controllers of the Galileo mission to crash the spacecraft
into Jupiter in 2003 so that microbes wouldn’t accidentally take seed
on what could be a habitable moon. Despite the best efforts of
spacecraft cleaners, some microbes seem to survive conventional
cleaning processes. This is why a new method is emerging that uses
ionized gas to kill the microbes.
“Plasma sterilization is a process not only compatible with modern
spacecraft, but it also enables successful removal and inactivation of
most resistant microbial species isolated in spacecraft assembly
facilities,” wrote Moeller. “The method is very fast. Full spore
inactivation of 100 million of bacterial spores was achieved in five
minutes, even with spores of Bacillus pumilus SAFR-032, which
encounters the highest resistance to UV radiation and further
sterilization methods,” wrote Katharina Stapelmann. (2/24)
