The Loyal Engineers
Steering NASA’s Voyager Probes Across the Universe
(Source: New York Times)
In the early spring of 1977, Larry Zottarelli, a 40-year-old computer
engineer at NASA’s Jet Propulsion Laboratory in Pasadena, set out for
Cape Canaveral, Fla., in his Toyota Corolla. A Los Angeles native, he
had never ventured as far as Tijuana, but he had a per diem, and he
liked to drive. Just east of Orlando, a causeway carried him over the
Indian and Banana Rivers to a triangular spit of sand jutting into the
Atlantic, where the Air Force keeps a base. His journey terminated at a
cavernous military hangar.
A fleet of JPL trucks made the trip under armored guard to the same
destination. Their cargo was unwrapped inside the hangar high bay, a
gleaming silo stocked with tool racks and ladder trucks. Engineers
began to assemble the various pieces. Gradually, two identical
spacecraft took shape. They were dubbed Voyager I and II, and their
mission was to make the first color photographs and close-up
measurements of Jupiter, Saturn and their moons. Then, if all went
well, they might press onward — into uncharted territory.
It took six months, working in shifts around the clock, for the NASA
crew to reassemble and test the spacecraft. As the first launch date,
Aug. 20, drew near, they folded the camera and instrument boom down
against the spacecraft’s spindly body like a bird’s wing; gingerly they
pushed it, satellite dish first, up inside a metal capsule hanging from
the high bay ceiling. Once ‘‘mated,’’ the capsule and its cargo — a
probe no bigger than a Volkswagen Beetle that, along with its twin, had
nevertheless taken 1,500 engineers five years and more than $200
million to build — were towed to the launchpad. Click here.

Small Rockets, Big
Dreams: The Race to Space Heats Up (Source: Ars Technica)
When most people think of a rocket launch, they think big. The Space
Shuttle, Falcon 9, and Atlas V all stand well over 50 meters tall, and
any of those would tower above the Statue of Liberty. They were made to
lift heavy things, weighing anywhere from 10 tons to considerably
larger, into orbit around Earth. But in recent years there has been a
lot of noise in the small rocket industry, promising cheap, expendable
boosters capable of carrying a few hundred kilograms into space.
As always in the aerospace industry, some of these efforts were
overhyped or had wildly optimistic timelines. For example, the industry
suffered a notable failure late last year when Firefly Space Systems
declared bankruptcy. However, a number of other companies have made
tangible progress this year, making it clear that this generation of
small satellite launch vehicles is closing in on their first commercial
flights. Click here.

NASA Contracts with BWXT
Nuclear Energy to Advance Nuclear Thermal Propulsion Technology
(Source: NASA)
As NASA pursues innovative, cost-effective alternatives to conventional
propulsion technologies to forge new paths into the solar system,
researchers at NASA's Marshall Space Flight Center in Huntsville,
Alabama, say nuclear thermal propulsion technologies are more promising
than ever, and have contracted with BWXT Nuclear Energy, Inc. of
Lynchburg, Virginia, to further advance and refine those concepts.
Part of NASA's Game Changing Development Program, the Nuclear Thermal
Propulsion (NTP) project could indeed significantly change space
travel, largely due to its ability to accelerate a large amount of
propellant out of the back of a rocket at very high speeds, resulting
in a highly efficient, high-thrust engine. In comparison, a nuclear
thermal rocket has double the propulsion efficiency of the Space
Shuttle main engine, one of the hardest-working standard chemical
engines of the past 40 years. That capability makes nuclear thermal
propulsion ideal for delivering large, automated payloads to distant
worlds. (8/2)
Orbital ATK Kicks Off
Follow-On Station Cargo Contract, Targets Next Antares Launch in October
(Source: SpaceFlight Now)
As Orbital ATK engineers aim for the next launch of the company’s
Antares rocket from Virginia this fall, early planning for missions to
keep the International Space Station supplied through the early 2020s
is already underway. The Cygnus supply ship is booked for at least 10
more hardware delivery missions to the space station, joining SpaceX’s
Dragon freighter and Sierra Nevada’s Dream Chaser spaceplane in the
U.S. fleet of unpiloted commercial cargo transporters under contract to
NASA.
Orbital ATK plans to send heavier loads, and perhaps large
unpressurized elements, to the space station in the future. SpaceX’s
Dragon and Japan’s HTV supply ship currently haul up payload packages
and spare parts for mounting outside the complex. NASA has penciled in
Oct. 11 for Orbital ATK’s next station cargo launch aboard an Antares
rocket from pad 0A at the Mid-Atlantic Regional Spaceport, a launch
complex located NASA’s Wallops Flight Facility on Virginia’s Eastern
Shore. (8/3)

Texas Man Admits He
Smuggled U.S. Space Technology to China, Russia (Source:
Daily Beast)
A businessman in Plano, Texas, pleaded guilty Thursday to smuggling
U.S. space technology to China and Russia by using his companies as a
cover. Peter Zuccarelli, 62 years old, said he tried to profit from
smuggling the radiation-protected microchips, violating the
International Emergency Economic Powers Act. He reportedly used his
eyeglass-lens companies to buy the microchips from U.S. manufacturers
and then shipped them to customers in the other countries with
incorrect labels. Such microchips are typically used in space probes
and satellites, but they can also be used for ballistic missiles in the
military. (8/4)
With Planetary Protection
Office Up for Grabs, Scientists Rail Against Limits to Mars Exploration
(Source: Science)
Since its arrival on Mars in 2012, NASA’s Curiosity rover has zapped
and drilled ancient rocks in the hopes of finding evidence for past
life. But it may never get a chance to investigate something far more
exciting: the possibility that martian microbes exist today. In the
coming years, as the rover trundles up the side of Aeolis Mons, it will
pass rocks that, seen from orbit, seem to host mysteriously
intermittent dark streaks—perhaps marking seasonal water seeps. But
NASA’s planetary protection office, charged with keeping earthly
microbes from colonizing other bodies, has said it may nix a visit. It
fears that Curiosity could contaminate this so-called special region
because the rover was not fully sterilized before launch.
To Alberto Fairén, a planetary scientist at Cornell University, that
makes no sense. Sooner or later humans—biped rovers that can’t be
sterilized—will set foot on the planet, hopelessly confounding any hope
of finding indigenous life, he and several colleagues argue in an op-ed
in press this month in the journal Astrobiology. “We need to
investigate Mars’s special regions carefully and fully prior to human
missions,” he says. Click here.

America’s Future in Space
is Both Commercial and Traditional (Source: Space News)
I recently had the opportunity to participate in a great panel session
discussing the role of commercial space in returning America to the
moon. I look forward to an active future in space that only a truly
competitive market can bring. However, my recent service on President
Donald Trump’s transition team at NASA has led me to understand that
treating space policy as though it were a team sport will not get us
there. The future is complex and challenging and we will need the
amazing capabilities and scale of the traditional players to get there.
In that spirit, I’d like to offer some unsolicited advice to friends in
both camps.
It’s great that NASA appears to be surviving this year’s government
budget cutting unscathed. The House Appropriations Committee in July
recommended a nearly $19.9 billion budget for NASA for 2018, about $800
million more than the Trump administration requested and nearly $300
million more than Congress approved for 2017. Click here.

Blue Origin Passes Over
Houston Spaceport in Favor of Alabama (Source: Houston
Chronicle)
Houston Spaceport lost out on a rocket engine manufacturing facility
that could have brought a $200 million investment and 342 well-paying
jobs. Blue Origin, the space company created by Amazon founder Jeff
Bezos, instead chose the established workforce and political sway of
Huntsville, Alabama. The project was expected to jump-start development
at the Houston Spaceport, which wants to create a cluster of aerospace
companies but has just one tenant. Losing the Blue Origin project was a
disappointment, but those involved remain optimistic that Houston will
land its next project and the spaceport will prove to be economically
viable. (8/3)
SpaceX Alum Now Launching
for One-Twentieth the Cost of SpaceX (Source: CNBC)
A company building tiny rockets is only a few launches away from
cracking open a multi-billion dollar market. Vector Space Systems on
Thursday flight tested its Vector-R launch vehicle from Spaceport
Camden in Georgia. The FAA-approved launch reached its targeted height
of 10,000 feet while carrying a commercial payload which included
packages from NASA, Astro Digital and the Center for Applied Technology.
The launch, partially funded by NASA, was a critical step in Vector's
plan to become the top transporter of micro-satellites. "The money in
these vehicles is made in making a lot of them and flying a lot of
them," CEO Jim Cantrell told CNBC. Cantrell's company is building the
Vector-R rockets to meet demand from companies that can't foot the bill
to ride along with SpaceX or United Launch Alliance but still need to
put satellites in orbit. (8/3)
Ferrofluid Propulsion for
Nanosatellites (Source: Universe Today)
When it comes to the future of space exploration, some truly
interesting concepts are being developed. Hoping to reach farther and
reduce associated costs, one of the overarching goals is to find more
fuel-efficient and effective means of sending robotic spacecraft,
satellites and even crewed missions to their destinations. Towards this
end, ideas like nuclear propulsion, ion engines and even antimatter are
all being considered.
But this idea has to be the strangest one to date! It’s known as a
ferrofluid thruster, a new concept that relies on ionic fluids that
become strongly magnetized and release ions when exposed to a magnetic
field. According to a new study produced by researchers from the Ion
Space Propulsion Laboratory at Michigan Tech, this concept could very
well be the future of satellite propulsion. (7/13)
Vector Launch Failed to
Sway Georgia Spaceport Opponents (Source: Spaceport Facts)
The rocket flown from Camden is legally classified as a Class 3 Amateur
rocket and is exempt from the normal safety considerations required for
orbital and satellite launching rockets. It is important to note that
just like their May 2017 launch, Vector's videos of the launch do not
show parachute deployment or the condition of the rocket after it
landed.
Pictures show that Vector had telemetry equipment on site and should
know exactly how high their rocket went. Maybe if they had disclosed
that airspace had been cleared to 5,500 feet, but the rocket made it
only to 1,000 or 2,000 feet, it would be an indication that the
2,000-mile drive to Camden wasn't really worth it. Is that why they did
not want the public or press to witness the launch?
Meanwhile, Camden County claims "making history", whatever that means.
The question elected officials have failed to answer for 2+ years is
how a tiny rocket company from Tuscon that hasn’t made it to 5,000
feet, without a commercially viable rocket, can launch from Spaceport
Camden anytime in the foreseeable future and repay taxpayers for their
$25 million investment. (8/3)
Vector Launches Test
Rocket from Spaceport Camden (Source: Brunswick News)
The liftoff of the prototype Vector-R launch vehicle, scheduled for 8
a.m. was delayed multiple times, including once for an auto-abort
ignition detection failure. Finally, around 12:15 p.m., many of the
more than 50 people in the parking lot listened to the countdown on
their smart phones before turning their eyes to the horizon to see
history being made. After waiting more than four hours, many said they
were disappointed.
Despite the crowd’s disappointment, Vector officials described the
launch as a “key milestone” in its attempts to provide commercial
orbital launch services. The rocket traveled straight into the air,
traveling less than 10,000 feet before falling back to earth. A small
parachute opened on the descent to get the rocket's nose pointing
toward the ground before a larger one opened at 1,000 feet to return
the vessel to earth intact.
An ongoing environmental assessment conducted by the FAA due to be
completed later this year will likely determine if rockets are ever
regularly launched into orbit from the site. Supporters believe a
spaceport could generate support industries that could generate
high-tech jobs in Camden County. Detractors say the county has already
spent millions of dollars on a project that will never be approved
because most of the launch trajectories are over Cumberland Island
National Seashore. (8/3)
