CubeSats: Tiny Payloads,
Huge Benefits for Space Research (Source: Space.com)
CubeSats reduce launch costs in two fundamental ways. They don't weigh
that much, which means a rocket doesn't need a lot of fuel to heft
them. In most cases, they also share a rocket with a larger satellite,
making it possible to get to space on the coattails of the heavier
payload.
There are some design challenges with CubeSats, however. The
electronics are smaller and are therefore more sensitive to radiation.
Because they are small, they cannot carry large payloads with them.
Their low cost also means they are generally designed to last only a
few weeks, months or years before ceasing operations (and for those in
low Earth orbit, falling back into the atmosphere.) (6/19)
Proposed Space Force
Would Pull Expertise From All Service Branches (Source:
USNI)
The White House’s proposed military Space Force would likely rely
heavily on existing personnel from inside the Navy, Marine Corps, Air
Force and Army, plus a host of other intelligence agencies, experts
said. Trump’s directive doesn’t provide mission specifics, but the
language suggests the Space Force would be charged with protecting both
commercial and government assets in space.
“As space becomes increasingly contested, the demand for the Department
of Defense to focus on protecting U.S. space assets and interests also
increases. At the same time, the rapid commercialization of space
requires a traffic management framework that protects U.S. interests
and considers the private sector’s needs,” the directive reads. But
before the proposed sixth branch of the military is formed, Congress
needs to approve legislation and the Department of Defense would have
to iron out the fine details, according to a Monday afternoon statement
from Pentagon spokeswoman Dana White. (6/19)
Former Astronaut
Criticizes Lunar Gateway Plans (Source: Space News)
A former NASA astronaut used an appearance at a National Space Council
meeting June 18 to argue that a key element of NASA’s plans to return
humans to the moon should be reconsidered. Appearing on a panel during
the meeting at the White House, Terry Virts said that the proposed
Lunar Orbital Platform-Gateway, a human-tended facility in orbit around
the moon, wasn’t an effective next step in human spaceflight beyond
Earth orbit after the International Space Station.
“It essentially calls for building another orbital space station, a
skill my colleagues and I have already demonstrated on the ISS,” he
said. “Gateway will only slow us down, taking time and precious dollars
away from the goal of returning to the lunar surface and eventually
flying to Mars.” Virts wasn’t specific on what should replace the
Gateway as that next step but called for an Apollo-like model of
stepping-stone missions to return to the moon, with ISS, he said,
serving well as the Mercury role. (6/18)

an interview that his company is in discussions about acquiring the
technical capabilities to produce the NK-33 and NK-43 engines from
United Engine Corporation, and would build a new factory to resume
production of those engines. Sopov suggested those engines, originally
developed a half-century ago for the Soviet N-1 moon rocket, could be
put to use on a version of the Soyuz-5 rocket that could launch from
Sea Launch's oceangoing platform. (6/18)

Venus Atmosphere Impacts
Spin (Source: Science News)
The dense atmosphere of Venus helps speed up the planet's spin. A study
published Monday found that the movement of the atmosphere over the
planet's mountains speeds up the planet's axial rotation by about two
minutes each day. That is a small fraction of the planet's day, which
lasts for 243 Earth days, and may be counteracted by other forces. That
interaction of the atmosphere, which rotates every four days, with the
surface can also explain the presence of a wave 10,000 kilometers long
seen in the planet's atmosphere. (6/18)
Trump Upends Careful
Planning for Increased Military Space Focus (Source: Space
News)
DoD was slow to react to the president’s announcement presumably
because only a handful of officials in OSD were alerted about it last
week, and the press office was not prepared to address reporters'
questions. Even those who had been warned the president would bring up
the Space Force at the NSC meeting didn't know exactly what he would
say. Over the past several months everyone could see that the Space
Force has become a fascination of sorts for Trump, even though the
Pentagon has opposed the idea.
Trump threw a big wrench into the Pentagon’s carefully laid out plans
to study how best to reorganize the military’s space forces. The House
Armed Services Committee's strategic forces subcommittee had been
pushing to create a Space Corps for the past two years. But the
language never got past the Senate. The 2018 NDAA directed the Deputy
Secretary of Defense to conduct a study and submit a final report by
December 31, 2018.
Ranking Democrat Adam Smith said it is “encouraging that President
Trump wants to increase our focus on space, but any change of this kind
would have to be legislated by Congress.” The House already passed a
defense bill last year mandating the creation of a Space Corps, and the
final version of that bill mandated an independent assessment of what
authorities would be needed, Smith noted. “If President Trump wants to
make such a change within the military services, he should come discuss
his proposal with us.” (6/19)
Robots and Automation Key
to Space Future (Source: Popular Mechanics)
Smart robots building space stations in orbit may be in the future, but
there are plenty of other examples of how smart robots and automation
are becoming critical to the future of spaceflight. The nation’s
busiest launch centers in Florida and California are expecting
exponential increases in launch tempo as communications companies loft
constellations of small satellites and new generations of air-launched
rockets and spaceplanes come of age.
This steady increase of space launches is about revolutionize Cape
Canaveral, but there’s one place where it’s prompting hair-pulling and
hyperventilation: the Federal Aviation Authority. FAA manages America’s
airspace, and airplanes must be rerouted to avoid space launch or
reentry operations. Currently, plotting the closures is done manually.
It’s a lot to account for, and all this can cause mistakes and delays.
The FAA sees automation as a critical tool in navigating a future with
more launches. Such an automated system would automatically determine
and carve out the appropriate airspace, and transmit that to the
community of air traffic controllers. It would be as easy as filing a
flight plan. (6/19)

Forget Galileo – UK Space
Sector Should Look to Young Stars Instead (Source: IMechE)
“British security firms could be BANNED from helping EU with Galileo
satellite project,” the Mail headline screamed. "Brexit to ‘force work
on Galileo sat-nav system out of UK’,” said the BBC. Then Airbus
offered to build a new UK system – “BREXIT REVENGE,” said the Express.
Scepticism followed – “Brexit Britain’s space ambitions are an
expensive waste of time,” claimed Wired.
Built as an alternative to the US GPS system, the EU’s 30-satellite
Galileo constellation is expected to be complete by 2020. The UK has
invested €1.4bn in the programme, and Airbus employs 100 people on the
project in Portsmouth. The system will provide free orientation to
public users and more accurate information for military uses. But
Brexit means the sensitive Airbus work will move to France and Germany,
while the UK faces losing access to the high-precision data.
“A small glitch along the way,” was the summary from Patrick Wood, UK
managing director of Lockheed Martin Space. “I think industry will
carry on and function.” ... “We have a healthy mix of science,
commercial and military capability. We have a close working
relationship in industry and academia, we have venture capitalists who
are supporting new entrants, and great business opportunities.” (6/18)
Pushing the limit: Could
Cyanobacteria Terraform Mars? (Source: Cosmos)
The bacteria that 3.5 billion years ago were largely responsible for
the creation of a breathable atmosphere on Earth could be press-ganged
into terraforming other planets, research suggests. A team of
biologists and chemists from Australia, the UK, France and Italy has
been investigating the ability of cyanobacteria – also known as
blue-green algae – to photosynthesise in low-light conditions.
Cyanobacteria are some of the most ancient organisms around, and were
responsible, though photosynthesis, for converting the Earth’s early
atmosphere of methane, ammonia and other gases into the composition it
sustains today. “Low-light adapted organisms, such as the cyanobacteria
we’ve been studying, can grow under rocks and potentially survive the
harsh conditions on the red planet.” (6/18)
SpaceX Risky Rocket Poses
a Problem (Source: Houston Chronicle)
The changing face of America’s next space race is a problem for
Houston, American astronauts and the United States’ legacy as a space
leader. Houston’s role in launching astronauts past Earth’s gravity,
landing on the moon and getting our astronauts home safely is
unquestioned. Now, reports indicate that SpaceX intends to use some of
NASA's money on faulty fueling technology that already caused to
explode on the launch pad...a method no space program incorporates into
a launch due to the risk.
This next generation space race presents an opportunity to continue
NASA's legacy of safety and innovation by sending NASA astronauts to
deep space aboard America’s exploration rocket, the Space Launch
System. Its crewed missions to the moon and beyond will be run from
Houston at Johnson Space Center’s historic mission control, ensuring
that Houston remains the epicenter of exploration and American
leadership.
We have a remarkable opportunity to change the trajectory of human
history with new space initiatives in the next few years, just as the
space race did in the 1960s. Moving forward, it is critical that we
focus on the things Houston got right the first time — safety,
innovation and the return trip. (6/18)
Hadfield: Rockets from
NASA, SpaceX, and Blue Origin Won't Take People to Mars
(Source: Business Insider)
We asked Chris Hadfield what he thinks about the future rocket ships of
three major players in the new space race: NASA's Space Launch System,
SpaceX's Big Falcon Rocket, and Blue Origin's New Glenn rocket. His
response isn't encouraging to those who'd like to see boots on Martian
ground within the next decade or two, let alone have people settle on
the red planet.
"Personally, I don't think any of those three rockets is taking people
to Mars," Hadfield told Business Insider. "I don't think those are a
practical way to send people to Mars because they're dangerous and it
takes too long." Hadfield's stance stems from the fact that all three
rocket systems rely on similar fuels (plus oxygen) to lift off Earth
and propel the ship through space. "My guess is we will never go to
Mars with the engines that exist on any of those three rockets unless
we truly have to," he said.
NASA's Space Launch System, expected to debut in the 2020s, will power
its engines with a combination of liquid hydrogen and solid chemical
fuels. Blue Origin, the rocket company founded by Jeff Bezos, is also
looking to use liquid hydrogen. SpaceX, founded by Elon Musk, is
staking its future on burning liquid methane, which the company
believes it can generate on the Martian surface. (6/17)
SpaceX is Giving Wall
Street a Reason to Bet on Tesla (Source: Quartz)
Automobile mass-production is a grueling exercise in optimizing the
factory floor with methodical precision that resists improvisation.
Mistakes that are fixable when making a few thousand cars become nearly
impossible to remedy when mass producing hundreds of thousands. Musk’s
unscripted moves in manufacturing electric vehicles, while achieving
what others deemed impossible, have cost Tesla dearly.
The ultimate expression of this approach is Space Exploration
Technologies, or SpaceX. Musk’s space company launches re-useable metal
tubes packed with explosives into space. Soaring hangers at the
company’s Hawthorne, California facility house hundreds of workers and
robots who carefully piece together the space-age materials that will
eventually become a multi-million-dollar rocket. There is still no such
thing as a mass-produced rocket. (6/12)
