Musk Concerned We Have
'No Defense' Against Potential Killer Asteroid (Source:
Fox News)
SpaceX CEO Elon Musk said that a large asteroid will eventually hit
Earth and his concern is that "we currently have no defense" for it.
Responding to a tweet from podcaster Joe Rogan, Musk said Sunday he
would not worry about the asteroid Apophis, which is expected to fly
past Earth in 2029. However, a "big rock" will eventually hit Earth and
as of right now, there's nothing we can do about it. (8/19)
SpaceX’s West Coast Drone
Ship Begins Panama Canal Transit on Journey to Florida (or Texas)
(Source: Teslarati)
After traveling more than 3500 miles (5600 km), SpaceX autonomous
spaceport drone ship (ASDS) Just Read The Instructions (JRTI) began its
eastbound transit of the Panama Canal on August 18th, placing the
vessel roughly two-thirds of the way to its unknown destination. JRTI’s
move came as a bit of a surprise and it’s still anyone’s bet if the
SpaceX recovery vessel heads for Texas or Florida immediately after
exiting the Panama Canal. Nevertheless, JRTI’s presence at either (or,
more likely, both) possible destinations arguably centers around the
imminent demands of a planned ramp-up of SpaceX’s Starlink satellite
constellation launch cadence, as well as an equally imminent need for
recovery assets to support the first suborbital Starship test flights.

Newt Gingrich Trying to
Sell Trump on a Cheap Moon Plan (Source: Politico)
Newt Gingrich and an eclectic band of NASA skeptics are trying sell
President Donald Trump on a reality show-style plan to jump-start the
return of humans to the moon — at a fraction of the space agency’s
estimated price tag. The proposal, whose other proponents range from a
three-star Air Force general to the former publicist for pop stars
Michael Jackson and Prince, envisions creating a $2 billion sweepstakes
pitting billionaires Elon Musk, Jeff Bezos and other space pioneers to
see who can establish and run the first lunar base.
That’s far less taxpayer money than NASA’s anticipated lunar plan,
which relies on traditional space contractors such as Boeing and
Lockheed Martin and is projected to cost $50 billion or more. Backers
of the novel approach have briefed administration officials serving on
the White House National Space Council, several members of the group
confirmed, though they declined to provide specifics of the internal
conversations.
Trump has yet to weigh in on the idea, at least publicly. But the
proposal, designed to offer a big incentive for private players who are
already planning their own moon missions, comes while the president has
expressed skepticism that NASA can achieve his goal of returning
American astronauts to the moon by 2024 without bold departures from
the status quo. Gingrich maintains that space entrepreneurs like Musk
and Bezos can rise to the challenge. And some of the companies told
POLITICO they are intrigued by the idea of such a competition. (8/19)

NASA Asks American
Companies to Deliver Supplies for Artemis Moon Missions
(Source: NASA KSC)
In another major step toward landing American astronauts on the lunar
surface by 2024, NASA is asking industry to respond to a Request for
Proposals to deliver cargo, science experiments and supplies to the
Gateway to support Artemis missions to the lunar surface. Commercial
supply services will support the agency’s Artemis lunar exploration
program which includes sending the first woman and the next man to
surface of the Moon within five years, and preparing for human
exploration of Mars.
The agency is seeking capabilities from American companies to deliver a
logistics spacecraft with pressurized and unpressurized cargo to the
Gateway for six months of docked operations followed by automatic
disposal. The logistics spacecraft must launch on a commercial rocket.
“We chose to minimize spacecraft requirements on industry to allow for
commercial innovation, but we are asking industry to propose their best
solutions for delivering cargo and enabling our deep space supply
chain,” said Mark Wiese, NASA’s Gateway logistics element manager at
Kennedy Space Center in Florida. (8/19)

Canceled SpaceX Projects:
Falcon Heavy Propellant Crossfeed (Source: Elonx)
One of the announced and abandoned SpaceX projects was crossfeed
funcionality for Falcon Heavy. It is a unique way of fuel transfer
between the side boosters and the rocket’s center core. The idea is
that each side booster would, in addition to its own engines, supply
fuel and oxidizer to three of the nine center core engines. Therefore,
only the remaining three center core engines would be supplied from the
center core tanks. Using this method (which has never been used in
practice), the center core would have consumed only about 15% of the
propellant in its tanks by the time the side boosters separated. This
results in a more efficient use of propellant which leads to higher
payload capacity.
First, let’s look at the history of the concept of propellant transfer
between rocket stages. In 1947, Mikhail Tichonravov came up with the
idea of parallel stages. In his scheme, three parallel boosters were
used, but the engines in the central stage were fueled from the side
boosters until they were depleted and discarded. This approach is more
efficient than traditional sequential staging because the engine in the
second stage is never just dead weight. Later, the Soviets conducted
engineering studies comparing rockets with sequential and parallel
stages, with and without fuel transfer between stages. The result of
this study was the R-7 Semyorka rocket. It became the basis of today’s
Soyuz rocket, but it doesn’t actually use fuel transfer between stages.
Transferring propellant across stages during flight is a hard
engineering problem which might not be worth solving when it results in
a 10% increase of an already-high payload capacity. On top of that,
Falcon Heavy’s payload capacity has increased by 17% since 2011, even
without crossfeed technology. It’s possible that if SpaceX wasn’t
focusing on Starship, they might have eventually developed crossfeed
for Falcon Heavy. But because there is no need for this type of
technology for Starship, which will eventually replace Falcon Heavy
anyway, crossfeed seems to be a dead end and was therefore canceled or
postponed indefinitely. (8/16)

Here’s the Stupid Reason
Elon Musk Wants to Nuke Mars (Source: The Next Web)
Elon Musk is on social media yapping about nuking Mars again. He’s not
trolling; he’s not acting as a provocateur; he really wants to bombard
the surface of our planetary neighbor with actual nuclear weapons.
Here’s why: he thinks it’ll kick-start the planet and make it habitable
by releasing trapped carbon dioxide into the atmosphere. He’s been
pushing this theory since at least 2015 when he told Stephen Colbert
that Mars was a “fixer-upper” and that we could fix it by nuking it.
According to scientists, he’s mostly wrong.
NASA research indicates that dropping nuclear weapons on Mars will
release some carbon dioxide, but not enough to alter conditions so
they’re remotely close to what we have on Earth. A 2018 study indicates
that there simply isn’t enough carbon dioxide on the planet to make
that big a difference. Currently, Mars‘ has an atmospheric carbon
dioxide content of about 0.6 percent of the Earth‘s. If we let Elon
Musk fire off nukes at it, scientists believe that’ll raise it to a
mere 7 percent of the Earth‘s content. (8/17)
Catch Rockets With a
Helicopter? Yep, That's the Plan (Source: WIRED)
In the span of just four years, reusable rockets have gone from
never-been-done to almost routine, at least at SpaceX. Blue Origin was
the first to land a rocket booster, in 2015, after a suborbital flight
to space. The following month, SpaceX landed the first-stage booster of
a Falcon 9 rocket that had gone into orbit. Since then, SpaceX has
landed boosters on drone ships in the ocean, and earlier this year it
landed all three boosters from its Falcon Heavy rocket for the first
time. If any other rocket maker hopes to compete, it has to figure out
how to recover its own rockets too.
While midair recovery of rockets sounds complicated, its proponents
argue that it’s actually less complex and less expensive than guiding a
rocket back to a landing pad. In many ways, it’s the same problem faced
by an outfielder trying to catch a fly ball in baseball. But in this
case the ball weighs thousands of pounds and is traveling several times
the speed of sound. Oh yeah, and the outfield is over 100 square miles
of open ocean. Easy enough.
In Rocket Lab’s design, its Electron rocket jettisons its payload and
then begins to fall back toward Earth. According to Rocket Lab CEO
Peter Beck, this is the toughest moment. As the booster sheds kinetic
energy due to air resistance, it heats up the atmosphere around it,
creating a blistering pocket of air. At the same time, a high-pressure
area at the leading end of the booster generates intense shockwaves.

How NASA is Becoming More
Business Friendly (Source: Phys.org)
A new case study demonstrates the steps being taken by the U.S.
National Aeronautics and Space Agency (NASA) to make it easier for
small businesses and entrepreneurs to understand its needs and do
business with it. The detailed case study, which provides insights on
the design, results, and lessons learned from these efforts, is
published in New Space: The Journal of Space Entrepreneurship and
Innovation. Jennifer Gustetic, NASA Headquarters, and colleagues from
NASA Ames , REI Systems, and the US Department of Energy coauthored the
article entitled "Making NASA More Business Friendly: A Small Business
Innovation Research and Small Business Technology Transfer Case Study."
They describe the three core initiatives of the effort to make NASA
more open to collaboration with small businesses. These included
developing an annual Request for Information (RFI), which offered an
opportunity for businesses to provide input and submit ideas. A second
initiative was the establishment of Industry Day, an annual small
business-NASA event that provided a forum in which small business
customers and NASA subject matter experts could convene, to increase
the likelihood for commercialization of innovations and successful
uptake of new technologies by NASA.
Lastly, NASA prioritized the modernization of its Electronic Handbook,
an IT system used to manage the solicitation of proposals and awards
process. The authors discuss the results of these efforts, draw
conclusions, and suggest future steps that can be taken to further
improve collaboration between NASA and the small business community.
