Landing Simulator Research To Help
Space Missions (Source: Florida Tech Current)
Florida Tech astronomy and astrophysics undergraduate students,
Ramanakumar Sankar and Timothy Drostare, created a landing simulator to
model the surface properties of airless bodies, like the moon and
asteroids, to find more reliable landing sites for space missions.
“Landing has been problematic in the past since scientists do not fully
understand the physical surface properties of airless bodies,” Sankar
said. Sankar and Drost were able to simulate the effects of solar
radiation on different porous surface models to observe their spectra.

Stratolaunch Lifts Veil on World’s
Biggest Plane — a Giant Bet on a New Way to Space (Source:
GeekWire)
“It’s jaw-dropping when you walk into that hangar,” said Chuck Beames,
Stratolaunch’s executive director and president of Vulcan Aerospace,
during a rare tour last week. The plane’s wing, taking shape inside a
103,000-square-foot hangar at the Mojave Air and Space Port, stands
three stories off the ground and measures 385 feet from tip to tip.
It doesn’t take long for the numbers – and the view – to boggle the
mind. But there’s another side to the Stratolaunch saga: What’s Paul
Allen up to? Stratolaunch is designed to serve as a flying platform for
sending satellites into orbit, but who will provide the air-launched
rockets? What niche will Stratolaunch fill alongside SpaceX, ULA, Blue
Origin, Virgin Galactic and other space companies?
Beames said Stratolaunch’s plane could launch multiple satellites, and
even multiple rockets, during a single flight. “You could go launch, go
launch, go launch, turn around and fly home,” he said. When the project
was announced, Stratolaunch said the plane would start flight tests in
2015 and start launching rockets in 2016. Today, Beames shies away from
giving a schedule, other than to say that Allen wants to have
Stratolaunch sending payloads to orbit by the end of the decade. Click here.

Stratolaunch Seeks Multiple Launch
Partners as Aircraft Nears Completion (Source: Space News)
As work on its giant aircraft nears completion, Stratolaunch Systems is
still working to line up partners to provide launch vehicles to serve
the growing small satellite market. Stratolaunch is still working with
a number of unnamed companies on launch vehicles that would be flown
from the plane, with plans to eventually work with multiple providers. Editor's Note:
The huge air-launch system has been baselined for operations at the
Cape Canaveral Spaceport. (6/20)
Australian Group May Buy Sea Launch
for Darwin-Based Operations (Source: Tass)
Russia is reportedly in talks with an unidentified Australian entity
regarding Sea Launch. Roscosmos head Igor Komarov said Saturday he has
had talks with various investors, including from Australia, about
purchasing the commercial launch company. Officials in the government
of Australia's Northern Territory said last week they have talked with
an unnamed investor who is interested in buying Sea Launch and moving
its assets, including a launch pad and command ship, to the territory's
capital city of Darwin. (6/20)
Russia and China Moving Toward Putting
RD-180 Engines on Chinese Rockets (Source: Tass)
Russia says a pending agreement will allow China to purchase RD-180
engines. Russian President Vladimir Putin will visit China later this
month and, among other activities, sign an agreement to protect
space-related intellectual property. That agreement, Russian Deputy
Prime Minister Dmitry Rogozin said, would allow Russia to conclude a
deal to sell RD-180s to China. It's unclear how China, which is
developing a new generation of rocket engines, would use the RD-180 on
its vehicles. (6/20)
Canada Will Hire Two New Astronauts
(Source: CBC)
If you've ever dreamed of riding spaceships, floating weightless in
space, and viewing the Earth from orbit, here's your chance. The
federal government is about to hire two new astronauts, the minister of
innovation, science and economic development has announced. The agency
says it is looking for candidates with "an academic background in
science or technology, excellent health, and a wide range of
outstanding qualities and skills." (6/17)
A Burial Plot for the ISS
(Source: LaunchSpace)
If the ISS were abandoned and left to naturally de-orbit, the 1,000,000
pound spacecraft would eventually reenter the atmosphere, break up and
scatter hundreds of pieces of debris with masses ranging from a few
pounds to 100,000 pounds possibly into any of the many highly populated
regions of the Earth. Thus, a controlled de-orbit is a matter of
international public safety.
The specific area is well-known as the "Spacecraft Cemetery." This
area, about 2,400 miles southeast of Wellington, New Zealand, is the
final resting place for many decommissioned satellites, including the
Mir Space Station and many trash-filled Progress Cargo Modules.
There are no islands in the area of the "cemetery," and the nearest
shores are thousands of miles away. This, combined with the fact that
ship traffic is light in this region, make it an ideal place for
spacecraft to plunge back to Earth. In fact, the cemetery is near Point
Nemo, the location which is furthest from any land mass, at 48.4
degrees south latitude and 123.4 degrees west longitude. The nearest
land is 1,600 miles south - Antarctica. (6/20)
Using The Stratosphere As Testing
Ground For Space (Source: Aviation Week)
They don’t produce attention-getting fire and smoke like rockets, but
high-altitude helium balloons are undergoing a quiet renaissance as
scientists, engineers and entrepreneurs use them for relatively
low-cost access to the doorstep of space.
As low Earth orbit (LEO) plays host to a new generation of spacecraft,
from student-built cubesats to the sophisticated human outposts fielded
by China and the International Space Station (ISS) partnership,
balloons afford trips to an environment that is essentially space with
gravity.
The stratosphere is high enough to generate valuable scientific
observations and to evaluate candidate hardware for spaceflight under
relatively realistic conditions, without the expense and launch loads
of actually going to space. Click here.
