China’s Satellite Imagery
Capabilities Coming into Sharper Focus (Source: Space News)
The Chinese government, which over the past 20 years has been one of
the world’s biggest markets for commercial Earth observation satellite
imagery, has achieved autonomy in medium-resolution imagery and expects
to reach that goal in submetric imagery within three to five years,
according to China’s Center for Resource Satellite Data and
Applications (CRESDA).
The good news for China’s domestic industry is not as good for the
half-dozen or more commercial satellite imagery companies, mainly in
North America and Europe, that have counted on China as a big growth
opportunity for the foreseeable future. (9/13)
RS-25: The Clark Kent of
Engines for the Space Launch System (Source: NASA)
In the iconic comic-book series, "Superman," the main character, Clark
Kent, looks like your average Joe. Under the ruse of a three-piece suit
and glasses, Kent's true identity is "Superman," who transforms into
his mighty persona to do battle for the good of mankind. In the rocket
engine world, the RS-25 is Clark Kent.
Four RS-25 engines will power the core stage of NASA's Space Launch
System (SLS). Towering more than 200 feet tall with a diameter of 27.6
feet, the core stage will store cryogenic liquid hydrogen and liquid
oxygen for propellant. SLS will be the most powerful rocket in the
world with the greatest capacity of any launch system ever built to
support any destination, any payload and any mission, including NASA's
plans to send humans to a captured and relocated asteroid. Click here.

Proton's Return-to-Flight
Mission Delayed by Glitch (Source: SpaceFlightNow.com)
Grounded since a startling launch failure in July, Russia's Proton
rocket will have to wait at least another two weeks to resume flights
due to a technical problem on the booster's first stage. The Proton
rocket's next flight, previously set for Sept. 16, will be delayed to
allow engineers to resolve a glitch on the launcher's first stage. "The
launch date will be determined at a later time," ILS said. (9/13)
Spacemen 'Flew Blind'
from Space Station as Sensors Failed (Source: Phys Org)
The three crew of the International Space Station (ISS) who returned to
Earth this week endured a hair-raising descent after their height
sensors failed, a Russian cosmonaut revealed on Friday. Pavel
Vinogradov said that he and the two other crew of the Soyuz capsule
which touched down in Kazakhstan Wednesday had groped their way through
the landing after they lost all data about their height from the
ground. (9/13)
Spacecraft Detects Gamma
Energy From Earth (Source: Florida Today)
On Aug. 11, NASA’s Fermi Gamma-Ray Telescope began a new phase of its
mission: a deeper study of the high-energy cosmos. In the first five
years, the Fermi telescope made many significant discoveries, including
the discovery of antimatter produced by thunderstorms.
Through mechanisms not thoroughly understood, so-called dark lightning
in thunderstorms generates brief but powerful bursts of gamma rays, the
highest-energy form of light. Known as terrestrial gamma-ray flashes
(TGFs), more than 800 have been recorded by the Fermi telescope. (9/12)

The fall semester at Embry-Riddle Aeronautical University marked the
kickoff of a new bachelor's degree program focused on Commercial Space
Operations. The CSO program began with a handful of students and is
expected to grow rapidly in coming semesters. Click here
