Rockets that Return Home
– SpaceX Pushing the Boundaries (Source:
NasaSpaceFlight.com)
SpaceX is continuing to advance the technology that is aimed at
creating a fully – and rapidly – reusable launch system, with the
recent addition of two key milestones towards that goal. While the F9-R
Dev-1 rocket enjoyed a debut hop at the McGregor Test Facility in
Texas, the first stage of the Falcon 9 v1.1 – that successfully lofted
the CRS-3 Dragon en route to the ISS – achieved a soft splashdown in
the Atlantic Ocean.
The ambitious plans for creating an advanced flyback booster-style
vehicle were unveiled by SpaceX founder Elon Musk back in September
2011, featuring first and second stages that would fly back to the
launch site under their own power – something no other aerospace
company has achieved. Industry sources believed the concept had
potential to work, but cautioned that SpaceX would lose so much
performance in their payload-to-orbit capability, the plan wouldn’t be
financially viable.
Elon Musk tweeted about last week's attempt: “Data upload from tracking
plane shows landing in Atlantic was good! Flight computers continued
transmitting for 8 seconds after reaching the water. Stopped when
booster went horizontal,” added the SpaceX boss. This information
pointed to a successful landing burn, which involved the relighting of
the center engine to stabilize the stage and reduce the vehicle’s
velocity prior to contact with the water. (4/22)

Arizona Senate To Review
Spaceport Measure (Source: KJZZ)
The Arizona Senate is to take up legislation today to pave the way for
a spaceport in the state. Tucson-based Paragon Space Development wants
to send a helium balloon with a capsule attached, containing two crew
members and six passengers, up about 20 miles above the Earth, where
they would float for a couple hours.
Taber McCallum of Paragon says a steerable parachute would then be used
to glide back to Earth, but he says where they would land is a little
unpredictable. “It varies with the time of year,” McCallum said.
“Sometimes you have lots of high winds and sometimes you don't. There
could be days when we come right back to where we started, and there
certainly could be days when we're 300 miles away.”
Paragon wants passengers to sign a waiver absolving the company of all
liability should something go wrong. It wants lawmakers to vote to make
that waiver enforceable. The cost of the flights would be about
$65,000, with the first launch expected in 2016. (4/21)

trip to Mars. ECA’s newest initiative, The Collaboratory, in
partnership with NASA’s Digital Learning Network, Google’s Connected
Classrooms Program, and the U.S. Embassies in Buenos Aires and Managua,
will engage middle school students from classes in Argentina,
Nicaragua, as well as those in New Jersey, Texas, and Washington, D.C.
in collaborative science activities.
The program will take place at the USA Science and Engineering Festival
(USASEF) in celebration of National Science Week, in an effort to
attract youth around the world to science, technology, engineering and
mathematics (STEM) education. During the festival on April 25 the students will
connect via Google+ Hangouts to explore the Red Planet and hear from
Mars subject matter experts. NASA will use current photos from Mars
Curiosity and its Mars Yard to simulate the field trip. (4/21)
The Only Watch That NASA
Astronauts Trust With Their Lives (Source: WIRED)
Back in the 1960s, NASA had a problem: To keep track of time while
bagging moon rocks, astronauts needed a wristwatch with otherworldly
ruggedness. Many high-grade chronographs were auditioned. One lost its
crystal under extreme decompression; the hands on another warped in the
test oven. But the Omega Speedmaster—and its particularly robust
movement—had the right stuff.
The watch has since been strapped to every astronaut’s wrist from
Gemini and Apollo to Skylab and the shuttle. Its movement, now known as
the Calibre 1861, has seen a few changes over the years to improve its
precision, but it’s been requalified by NASA for each new mission, and
it remains the most strenuously tested movement in history.
It’s even performed a few tasks those neurotic engineers couldn’t have
foreseen: After shutting down their computers to save power, the
troubled Apollo 13 crew navigated back to Earth using their hand-wound
Speedmasters. (4/22)

Editorial: Tough
Balancing Act for Arianespace (Source: Space News)
Launch services provider Arianespace routinely juggles a complicated
manifest involving three rockets, the largest of which is designed to
carry two satellites at a time — typically for different customers.
This task is made immeasurably more difficult by late-arriving
satellites, which force the company to constantly rearrange schedules
and delay launches, sometimes at the expense of a customer that
delivered its satellite on time.
On rare occasions, this process can lead to situations where
Arianespace must choose between two late-arriving customers vying for
the same backup launch slot. The company faced that uncomfortable
prospect recently with two key customers: the European Union, owner of
the Galileo satellite navigation system, and O3b Networks, the
broadband services startup whose majority shareholder is SES, the
world’s second-largest satellite operator by revenue. (4/22)

Space Coast Project Could
Destroy Bird Habitat (Source: Brevard Times)
Although Florida and Brevard County taxpayers have spent more than $48
million to preserve natural lands in Brevard County to protect
threatened and endangered species, the North Brevard Economic
Development Zone (NBEDZ) is proposing that taxpayer money be used for a
project that could destroy the habitat of the threatened Florida Scrub
Jay and gopher tortoise.
On the agenda for an April 22 Titusville City Council meeting is a
request from NBEDZ for $50,000 for an engineering study to further
develop Spaceport Commerce Park in an effort to attract more businesses
to that site. According to the January 2014 NBEDZ meeting minutes, an
environmental consultant told the NBEDZ Board that the 178-acre
Spaceport Commerce Park is comprised of 19 acres of occupied Scrub Jay
habit. Additionally, 43 gopher tortoises were identified on
site in a recent survey.
The environmental consultant estimated that it would cost $1,200 to
permit and relocate a gopher tortoise plus $59,000 per acre to offset
Scrub Jay habitat, and $85,000 per acre to offset wetland impacts.

Launch Unlocks Manifest
for Orbcomm, AsiaSat (Source: SpaceFlight Now)
Friday's liftoff of a Falcon-9 rocket cleared a bottleneck in SpaceX's
Florida launch schedule that forced two commercial customers, Orbcomm
and AsiaSat, to keep their completed satellites at their factories to
wait out launch delays. SpaceX founder and CEO Elon Musk said Friday
the company still expected to launch 10 Falcon-9 rockets this year
despite the delays.
With the Jan. 6 liftoff of the Thaicom 6 telecom satellite and Friday's
launch of a Falcon-9 rocket with SpaceX's Dragon cargo spacecraft to
the International Space Station, eight more missions are on the
Falcon-9 manifest this year. Four of the launches are booked by New
Jersey-based Orbcomm and AsiaSat of Hong Kong.
Not all of the delays leading up to Friday's launch were the fault of
SpaceX, which found itself at the mercy of the U.S. Air Force's Eastern
Range and the often-tricky scheduling of operations involving the
International Space Station. SpaceX needs to achieve about one Falcon-9
launch per month to pull off 10 flights this year, replicating a
one-month turnaround SpaceX demonstrated between two Falcon-9 missions
in early December and early January with the SES 8 and Thaicom 6
television broadcasting satellites. (4/22)
Tricks Elon Musk and Jeff
Bezos Use To Run Meetings (Source: Business Insider)
Musk has incredibly high standards. He has a reputation for firing
people if they miss a deadline. So if you're meeting with him at Tesla
or SpaceX, you have to be ready. As one anonymous Musk employee shares
on Quora: "When we met with Elon, we were prepared," the commenter
shared. "Because if you weren't, he'd let you know it. If he asked a
reasonable follow up question and you weren't prepared with an answer,
well, good luck."
Bezos likes to get people arguing. If you work at Amazon, you'd better
be comfortable with conflict. Bezos is famous for hating "social
cohesion," that tendency people have for finding consensus for no other
reason than it feels good. "Leaders are obligated to respectfully
challenge decisions when they disagree, even when doing so is
uncomfortable or exhausting. Leaders have conviction and are tenacious.
They do not compromise for the sake of social cohesion." (4/21)
