Orbital Launch Date from NASA Wallops
Scheduled (Source: WBOC)
Orbital has set July 11 as the targeted date for the launch of the
Orb-2 mission to the International Space Station, the second
operational cargo resupply mission under the company’s Commercial
Resupply Services contract with NASA. The targeted launch time from the
Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility on
the Eastern Shore of Virginia will be 1:40 p.m., NASA said Thursday.

Dropship Offers Safe Landings for Mars
Rover (Soure: ESA)
The dramatic conclusion to ESA’s latest StarTiger project: a ‘dropship’
quadcopter steers itself to lower a rover gently onto a safe patch of
the rocky martian surface. StarTiger’s Dropter project was tasked with
developing and demonstrating a European precision-landing capability
for Mars and other targets. The Skycrane that lowered NASA’s Curiosity
rover onto Mars showed the potential of this approach, precisely
delivering rovers to their science targets while avoiding rock fields,
slopes and other hazards. Click here.

Sudden Power Loss Leaves a Galileo
Satellite in Safe Mode (Source: Space News)
One of the four European Galileo positioning, navigation and timing
satellites stopped transmitting on two of its three channels May 27
because of a sudden loss of power, forcing ground teams to shut down
the satellite after putting it in safe mode while examining possible
causes, European government officials said.
These officials said the anomaly, which as of July 3 had not been
resolved, occurred in a matter of seconds May 27 and shut down the E1
signal first. That signal, which transmits Galileo’s Open Service,
re-established itself almost immediately. But as soon as it was back in
service, the two other channels’ power dropped and did not recover. The
full satellite then was shut down by ground teams. (7/3)
Northrop, Boeing Respond to U.S. Air
Force GPS 3 Solicitation (Source: Space News)
Northrop Grumman and Boeing say they have responded to a U.S. Air Force
call for contractors interested in building the service’s next batch of
GPS position, navigation and timing satellites. Lockheed Martin holds a
multibillion-dollar contract to build eight next-generation GPS 3
satellites, the first of which is slated to launch in 2016. The U.S.
Air Force’s space acquisition arm is looking for possible challengers
to Lockheed Martin to build the next batch of satellites. (7/3)

Russia launched on Thursday a light-class Rokot carrier rocket with
three telecoms satellites from its northern Plesetsk space center, the
Defense Ministry said. "The launch of the Rokot carrier rocket with
three Gonets-M communications satellites was carried out successfully
... from the Plesetsk space center," spokesman for Russia's Aerospace
Defense Forces, Col. Alexei Zolotukhin said. (7/3)
Odd Exoplanet Find Hints at Many
Earth-Like Worlds (Source: Space.com)
Astronomers have for the first time detected a rocky alien world in an
Earth-like orbit around just one star in a two-star system. The new
find suggests that such worlds may be common, and the strategy used to
discover the planet could help reveal more exoplanets in the future,
researchers say. Although Earth orbits a single star, most sun-like
stars are binaries, two stars orbiting each other as a pair. In fact,
there are many three-star systems, and even some that harbor up to
seven stars. (7/3)
Government Argues for Dismissal of
SpaceX Contract Complaint (Source: CBS)
"SpaceX's complaint is amorphous," the motion claims. "Rather than
challenge a single procurement action, SpaceX broadly protests any
sole-source purchase of single-core evolved expendable launch vehicles
(EELV) and associated launch services. This challenge appears to
implicate the United States Air Force's entire EELV program --
including past and future purchases under various contracts." (7/3)
NASA Needs an Indian Tutorial
(Source: Bloomberg)
What can the U.S. space program learn from the Indian one? Not much, if
the standard is outer-space achievement: India's modest record mostly
includes feats the U.S. accomplished decades ago. But if the standard
is having a clear vision of what you want to accomplish -- and getting
that done quickly and economically, there might be a lesson or two.
Vikram Sarabhai, the physicist regarded as the patriarch of India's
space program, is quoted dismissing the notion that India should
compete with rich, developed countries to explore the moon and planets.
Rather, the purpose of India’s space program is “the application of
advanced technologies to the real problems of man and society.” It's
interesting to set that against the uncertain priorities of the U.S.
space program since the end of the Apollo moon-landing program more
than 40 years ago.
To be sure, the U.S. space program has accomplished a lot in the last
50 years, in spite of flighty, shifting priorities. But the absence of
a national rationale for space exploration has resulted in a NASA that
lacks clear direction and is hamstrung by an aging bureaucracy
incapable of spending the agency’s considerable funding in a manner
that satisfies anyone. Contrast that with ISRO, whose low budgets and
expectations, combined with a pragmatic, results-driven vision, have
more than met its modest goals. (7/3)
‘The Satellite’ Is A Science Project
To Bring You A Live Portrait Of Earth (Source: Tech Crunch)
The Satellite is a project created by two New York University
instructors who are attempting to create a live-view, photorealistic
portrait of Earth with real-time imagery and remote sensing data from
hundreds of satellites. By gathering live data from satellites, the
team hopes to create a live representation of Earth that is close to
what it would actually look like from the International Space Station.
They want to create and design the right architecture for this project,
which will include six high-resolution projectors and a spherical
screen for the best viewing performance. NASA is offering support to
the project in the form of advice from astronaut and engineer Charles
Camarda. The team also has several advisers from NYU, where the project
started about a decade ago.
One challenge they have is working with weather data, as it is
constantly changing. Land masses don’t have to be rendered as quickly.
The team describes The Satellite as a public project and hopes it can
receive more sponsors and even interested parties to help with its
development and installation. (7/3)
Success! Private Team Fires
36-Year-Old NASA Probe's Engines (Source: Space.com)
An old NASA spacecraft under the control of a private team fired its
thrusters yesterday (July 2) for the first time in a generation. NASA's
International Sun-Earth Explorer 3 probe (ISEE-3), which the agency
retired in 1997, performed the maneuver in preparation for a larger
trajectory correction next week. The spacecraft hadn't fired its
engines since 1987, ISEE-3 Reboot Project team members said.
It took several attempts and days to perform the roll maneuver because
ISEE-3 was not responding to test commands. But this time, controllers
got in touch. They increased the roll rate from 19.16 revolutions per
minute to 19.76 RPM, putting it within mission specifications for
trajectory corrections. (7/3)
Exoplanets Once Trumpeted as
Life-Friendly May Not Exist (Source: Science News)
Two planets considered among the most promising for life outside the
solar system don’t exist, scientists report. The signals embedded in
starlight that were attributed to the planets may instead have been
caused by the changing magnetic activity of their star, Gliese 581.
Although the study isn’t the final word on these enticing yet
controversial worlds, scientists say it reinforces the need for
meticulous analyses to separate planets’ signals from those generated
by spots and flares on stars. (7/3)
Young Stars Vibrate Faster as They Age
(Source: Science News)
As infant stars get closer to becoming full-fledged suns, they pulse
faster, according to research in the July 4 Science. The discovery
provides astronomers with a new tool for probing stellar nurseries and
learning more about how stars form. The team matched the frequency at
which young stars vibrate to attributes like temperature and
brightness. In one young star cluster, NGC 2264, the researchers
realized that stars have been forming for much longer than its assumed
few-million-year age. (7/3)

The European Space Agency (ESA) Intermediate eXperimental Vehicle (IXV)
is enjoying a stay in Holland ahead of being shipped to Kourou, French
Guiana to meet up with her Vega launch vehicle. The IXV space plane is

The IXV will demonstrate Europe’s advanced re-entry technologies and
