Take a Closer Look at SpaceX’s
Recovered Falcon 9 Rockets (Source: Observer)
In order to guide a Falcon 9 booster back to Earth, SpaceX utilized a
set of 4 aluminum grid fins. Elon Musk said that the current fins are
always taken to the threshold of how much heat they could withstand.
Sometimes, the aluminum fins even ignite. To solve this problem, SpaceX
forged 4 solid titanium grid fins and flew them for the first time on
last Sunday’s Iridium-2 mission. “Flying with larger &
significantly upgraded hypersonic grid fins,” Musk tweeted. “Slightly
heavier than shielded aluminum, but more control authority and can be
reused indefinitely with no touch ups.” Cick here.

SpaceX’s Single-Minded Pursuit of Rocket Reusability (Source:

Reusing the first stage of a rocket, the largest and most expensive
component because of its cluster of nine powerful engines, has been
part of SpaceX’s goals since the beginning. The latest launches are a
sign it is starting to become routine. But until recently, the mere
idea was scoffed at by the most experienced players in the industry.
Rockets were only economical as “expendable” systems, used once and

Trump’s New National Space Council is
Already Baffling the Space Industry (Source: Quartz)
With no fanfare, US president Donald Trump signed an executive order
today to re-form the National Space Council, creating a new body to
coordinate space policy across the government. Vice president Mike
Pence will chair the council, which president Clinton shut down in
1993. Its work will include coordinating space spending between NASA,
the Air Force, and intelligence agencies, and leading the US through a
period in which a burgeoning private industry is trying to lower the
cost of space access and start doing business in orbit and beyond.
Today’s long-awaited event doesn’t signal a strong commitment by the
White House. It wasn’t included in the president’s pre-announced
schedule, andWhite House spokespeople declined to confirm or deny it
was happening until minutes before the event began. Holding an
un-televised event on the Friday before a holiday weekend isn’t a way
to gin up popular support for a bold space agenda.
“I’ve heard this rumor for several days and am perplexed as to why [the
White House] isn’t making a big deal out of it,” tweeted Marcia Smith,
who has observed US space policy for four decades as a congressional
aide and then editor of Space Policy Online. “And having waited so
long, why not wait a couple weeks more and do it on July 20?” (7/1)
SpaceX is Having a Very, Very Good
Year... So Far (Source: Mashable)
SpaceX is having a pretty great year. It's only June and the Elon
Musk-founded company has already launched nine missions to orbit,
exceeding their previous annual launch total of eight. (Not to mention
the fact that two of those launches occurred within 48 hours of one
another last weekend.)
Musk and others working for SpaceX have long said that their ultimate
goal is to make private spaceflight — including rocket landings,
launches, reused spacecraft, etc. — feel routine to the general
population. This year is starting to prove out that idea more and more.
We're beginning to lose track of how many rocket landings SpaceX has
successfully performed (it's 13, by the way, but we had to count).
"So nine itself is not blowing out their previous record. However, the
significance comes from the fact that it's only June, so they have time
to pass their previous record by a wide margin," Bill Ostrove said.
"Another factor in SpaceX's favor is the fact that they successfully
conducted three launches in June. If they can continue launching two to
three satellites per month they could pass their old record by a wide
margin." This would put them on par (or beyond) ULA, which launches
about 12 to 15 times per year. (7/1)
No Space for New Space at Space
Council Rollout (Source: Ars Technica)
Neither Pence nor Trump directly addressed this issue in their remarks,
which were largely platitudes about making America great again in
space. However, the composition of the crowd was illustrative, as it
seemed to favor NASA's traditional contractors, who are building the
SLS rocket and Orion spacecraft. After the event, the Coalition for
Deep Space Exploration noted that many of its members were invited.
Most of these companies are prime- or subcontractors on the SLS rocket
and Orion.
The coalition's president, Mary Lynne Dittmar, noted how NASA's deep
space program supports a wide industrial base across the country,
saying, "These programs are critical to our 50-state supplier network,
our national industrial base innovation and manufacturing job creation
in so many communities across the country."
The primary advocate for new space companies, the Commercial
Spaceflight Federation, was not invited to the event. SpaceX's Elon
Musk and Blue Origin's Jeff Bezos were asked to attend, but neither
could make it on short notice. One official involved in the new space
community said, "If you were not with Alabama or SLS, you weren't
getting into the event today. They didn't want any commercial space
there." (7/1)
Will NASA Suffer as Trump
Administration Tightens Control? (Source: Parabolic Arc)
President Donald Trump has signed an executive order reconstituting the
National Space Council under Vice President Mike Pence to better
coordinate space policy and activities across the government. Experts
are split on whether the council will succeed in its goal or simply add
another level of frustrating bureaucracy on top of the existing system.
There is another concern, however, that has received minimal attention
thus far.
This is the first step of the White House imposing more control over
NASA. Step 2 will come when Trump gets around to nominating a new
administrator and deputy administrator to lead the space agency. I am
concerned about what will happen at that point. The administration has
already proposed eliminating all or parts of five environmental
projects from NASA’s budget as well as closing down NASA’s education
program. I fear worse may be to come.
I worry that a new leader at NASA could take similar steps in an effort
to align the space agency with the administration’s political ideology.
That could be very bad for the space agency in the long run. NASA is
the gold standard in terms of government agencies. It’s widely
respected the world over for its achievements and its integrity. It
routinely wins polls as the best place to work in government. And it
operates in a very open manner with the press and the public. (7/1)
Reasonable Compromise on Spaceport
America Funds (Source: Las Cruces Sun-News)
The New Mexico Finance Authority reached a reasonable compromise
recently when it agreed to let the Spaceport Authority use excess money
from a local gross receipts tax to help fund operations at the
spaceport for one year. Spaceport officials had been seeking permanent
use of the money, while opponents requested that its use be ended
immediately. Instead, the Finance Authority approved usage for one
year, with plans to revisit the issue next year.
In 2007, voters in both Doña Ana and Sierra Counties approved increases
in their local gross receipts tax to help fund construction of the
spaceport. The measure passed by less than 1 percent in Doña Ana
County, and only after then-Gov. Bill Richardson had warned that
failure to pass the tax hike would kill the deal.
Revenue from the new tax has paid off about $43.8 million in bond debt
for the spaceport’s construction, with another $74.2 million in
payments due through 2029, according to the Santa Fe New Mexican. At
issue is money collected from the local tax in excess of what is needed
to make payments on the bond. (7/1)
Space Junk Solution? Tiny Cubesat to
Test New De-Orbiting Thruster (Source: Space.com)
A tiny satellite that reached orbit last week will make history when it
comes back down to Earth later this summer. The D-Sat cubesat, which
was developed by Milan-based startup D-Orbit, soared into space atop
India's PSLV rocket on June 23. D-Sat is fitted with an independent
thruster system known as the D-Orbit Decommissioning Device (D3), which
is designed to help mitigate the growing space-junk problem.
When D-Sat's mission comes to an end in July or August, D3 will guide
the satellite to a controlled destruction in Earth's atmosphere — the
first-ever such maneuver for such a small spacecraft, D-Orbit
representatives said. D-Sat's purpose is to demonstrate the technology,
with the aim of inspiring commercial satellite manufacturers and
operators to consider it for their missions. (7/1)

NASA Has Found 16,000 Asteroids Near
Earth. Don't Panic. (Source: Vox)
Billions of years ago, when the solar system formed, it left behind
large chunks of space rocks that weren't big enough to become planets.
There are millions of such rocks, called asteroids, in our solar
system. An estimated 1 million to 2 million large asteroids exist in
the space between Mars and Jupiter.
In 1998, and then again in 2005, Congress told NASA to find these
objects and make plans for diverting ones that posed a risk to Earth.
More than 16,000 of them are considered near-Earth objects because
sometimes they come as close as a mere 28 million miles from us — a
hair's breadth away in cosmic terms. NASA is mainly trying to detect
the small- and medium-size asteroids that could damage cities. (7/1)

The Vice President will tour Kennedy and learn more about the center’s
work as a multi-user spaceport for commercial and government clients,
as well as see the agency’s progress toward launching from U.S. soil on
spacecraft built by American companies, and traveling past the moon,
and eventually on to Mars and beyond with the help of NASA’s new Orion
spacecraft and Space Launch System rocket. (6/30)
Identifying Illegal Waste
Sites from Space (Source: Trajectory)
UK startup Air and Space Evidence—the self-proclaimed “world’s first
space detective agency”—is launching a new “Waste from Space” service
that will use satellite imagery to identify illegal deposits of waste
on Earth. The service is an application of the company’s newly
developed semi-automatic detection model, which combines satellite data
with machine learning algorithms to locate large swathes of
unidentified materials—the worst of which can contain up to hundreds of
thousands of tons of trash.
Air and Space Evidence received funding this year from the European
Space Agency, Open Data Incubator for Europe, and the Scottish EPA to
research its waste surveillance capability and run preliminary tests.
In product trials, the algorithms were 71 percent at pinpointing
unlicensed waste sites. Waste crimes such as illegal dumping cause
significant environmental degradation and public health risks, and are
estimated to cost the UK £604 million each year in cleanup costs and
lost revenue from taxes. (6/30)
AIA Leads Call to Address
NOAA Satellite Interference Issue (Source: AIA)
The Aerospace Industries Association is a leading voice in opposing
plans by Ligado to share spectrum currently used by weather satellites,
citing the need to address interference issues. "Contrary to the
assertions in Ligado's FCC advocacy and recent media blitz, its
proposed terrestrial operations continue to pose a significant
interference risk to numerous parties that receive real-time weather
and related environmental information from [NOAA], certified GPS
receivers and aeronautical safety SATCOM relied upon by the aviation
industry, and Iridium's 869,000 government and commercial subscribers,"
states a letter signed by AIA, AccuWeather, Iridium, the International

Space Sector Stable but
Still Dwarfed by the Aviation Sector (Source: SpaceFlight
Insider)
The Aerospace Industries Association (AIA), a trade association
representing leading aerospace and defense (A&D) companies in
the U.S., has recently published its report entitled “2017 Facts
& Figures”, which reveals key numbers about A&D
industry’s economic impact. Among other things, the summary highlights
the condition of the space systems sector as part of the A&D
industry.
According to the document, in 2016, the U.S. A&D industry
supported 2.4 million American jobs. By industry group, employment for
2016 accounted for the following: 547,900 for aeronautics/aircraft,
79,000 for space systems, 140,900 for land and sea systems, and 77,700
for cyber. Employment in the space systems sector has been stable
during recent years as since 2011 the number of jobs in this segment
fluctuates between 79,000 and 80,800.
However, sales in this sector remained stagnant. In 2016, space systems
generated $40.4 billion out of $450.1 billion overall attributed to
A&D firms producing end-use goods and services. This value has
not exceeded $42.2 since 2010. (6/30)
