SpaceX is Using a
Powerful Rocket Technology. NASA Advisers Say it Could Put Lives at
Risk. (Source: Washington Post)
When Elon Musk and his team at SpaceX were looking to make their Falcon
9 rocket even more powerful, they came up with a creative idea — keep
the propellant at super-cold temperatures to shrink its size, allowing
them to pack more of it into the tanks. But the approach comes with a
major risk, according to some safety experts. At those extreme
temperatures, the propellant would need to be loaded just before
takeoff — while astronauts are aboard. An accident, or a spark, during
this maneuver, known as “load-and-go,” could set off an explosion.
The proposal has raised alarms for members of Congress and NASA safety
advisers as the agency and SpaceX prepare to launch humans into orbit
as early as this year. One watchdog group labeled load-and-go a
“potential safety risk.” A NASA advisory group warned in a letter that
the method was “contrary to booster safety criteria that has been in
place for over 50 years.”
Concerns at NASA over the astronauts’ safety hit a high point when, in
September 2016, a SpaceX Falcon 9 rocket blew up while it was being
fueled ahead of an engine test. The fueling issue is emerging as a
point of tension between the safety-obsessed space agency and the
maverick company run by Musk, a tech entrepreneur who is well known for
his flair for the dramatic and for pushing boundaries of rocket
science. Click here. (5/5)
It's No Wonder Nasa is
Intimidated by Elon Musk's BFR Rocket (Source: The Herald

Any tax-funded spacefaring organization certainly has good reason to
feel a bit defensive these days. After decades of dominance, NASA now
faces cultural obsolescence with the rise of two privately-owned young
pretenders – SpaceX and Amazon boss Jeff Bezos’ Blue Origin.
These cash-rich upstarts lean heavily upon showmanship and
razzle-dazzle, willingly inviting hyperbolic headlines and hysterical
levels of hype for what are essentially just minor test launches. Many
casual observers are under the impression we’ll soon be living in
Martian cities and canoodling with exotic aliens, but the fact remains
that no-one in the aeronautics industry is anywhere near launching a
manned flight to Mars – never mind colonising the red planet with
casinos and coffee shops.
It’s a very long way off – yet, these firms have to keep the
near-future dream alive so investors think they’ll walk on Mars in
their lifetime. Where Musk and Bezos’ firms do excel, however, is in
making innovative breakthroughs in propulsion technology at a rate the
red-tape bound bureaucratic nightmare that is NASA just can’t match.

Forget About Sending
Humans to Mars -- We Need a Permanent Moon Base Instead
(Source: FOX News)
On Tuesday the three-day Human to Mars Summit kicks off in Washington
to discuss the far more ambitious mission of sending men and women to
Mars. NASA Administrator Jim Bridenstine is one of many NASA officials
scheduled to speak, along with officials of companies interested in
space exploration, scientists, engineers, people from the entertainment
industry and many others.
It’s only natural that in addition to sending unmanned exploratory
vehicles to Mars we pull out the national checkbook and spend billions
of dollars to send astronauts there to explore for themselves, right?
Actually, it would be wrong. Sending humans to Mars – at least any time
in the next few decades – would be a costly mistake. Instead, we need
to use our limited resources to return to the moon and set up a
permanent base, and do more to protect our Earth-orbiting satellites.
This is a mission our national security demands.
President Obama acted foolishly when he allowed our human spaceflight
program to be basically zeroed-out in federal budgets approved during
his time in office. President Obama allowed Russia and China to catch
up to the U.S. in manned space travel between Earth and the moon – our
“backyard” in space – and what could be the ultimate high ground in a
future war. President Trump has the opportunity to reverse President
Obama’s devastating and dangerous misjudgment and once again –
following the example of President Kennedy – make America great again
in space. (5/6)
SpaceTime Enterprises
Will Turn You Into a Virtual Space Tourist (Source:
Venture Beat)
Let’s face it; VR might happen in our lifetime but accessible,
affordable space tourism might not. At least, not any time soon. But
In-Space Missions and Rewind want to use VR and AR to bring us closer
to being an astronaut than ever before.
This week the pair announced SpaceTime Enterprises. This U.K.-based
initiative that will see multiple satellites launched into low Earth
orbit. These satellites will be fitted with cameras capable of
broadcasting images of space in real-time and even overlaying
information such as meteorological systems, atmospheric phenomenon,
celestial bodies and more. Down on Earth, we’ll be able to view these
images in VR, allowing us to visit miles above our own planet without
ever having to step out the front door.
The initiative will look to develop apps using the information it
captures that be used in both VR and AR. The hope is to create
experiences for consumers, students, ecologists, scientists, business
owners and others. (5/6)
'The Martian' Movie 'is
Completely Doable.' But Elon Musk's City on Mars is Another Story.

"[Musk's] idea about colonizing? That's going to require ...
bioregenerative life support capabilities," Porterfield said. The idea
behind bioregenerative life support, which Porterfield worked on at
NASA, is to collect a human crew's breath, liquid waste, and solid
waste — then use plants and other life forms to recycle it into fresh
food, water, and air. This would dramatically reduce the need for
resupply missions and help ensure a crew's long-term survival. It would
also make a colony vastly more sustainable, affordable, and
independent. Click here.
