The Russian Orbital Segment (ROS) is the name given to the components of the International Space Station (ISS) constructed in Russia and operated by the Russian Roscosmos. The ROS handles Guidance, Navigation, and Control for the entire Station.
The segment currently consists of six modules, which together essentially comprise the base configuration of the cancelled Russian space station Mir-2. The segment is controlled directly from Roskosmos’s Mission Control Center in Moscow. The six modules are:
To settle the solar system we’ll have to bring water to planets drier than Dune, and Comets offer one such source of water, but how do we move them where we need them?
ULA President and CEO gives an overview of how Atlas V, one of the most reliable rockets in the world, carries an extra layer of safety for its solemn duty of launching astronauts on human spaceflight missions.
At ~700 km above Earth, the EVA suit will support the Polaris Dawn crew in the vacuum of space during the first-ever commercial astronaut spacewalk.
Evolved from the Intravehicular Activity (IVA) suit, the EVA suit provides greater mobility, a state-of-the-art helmet Heads-Up Display (HUD) and camera, new thermal management textiles, and materials borrowed from Falcon’s interstage and Dragon’s trunk.
Building a base on the Moon and a city on Mars will require millions of spacesuits. The development of this suit and the execution of the spacewalk will be important steps toward a scalable design for spacesuits on future long-duration missions as life becomes multiplanetary.
Langley Research Center Unpressurized Crew Transport
with Surface Habitat: 0605-LLPS-LaRC-2
This was a two-stage lander that incorporated unique,
dockable rear-entry space suits for a crew of four on an
unpressurized ascent stage. The ascent stage mission
was designed for a nominal surface stay time of 7 days,
and a return payload capacity of 100 kg (220 lbm).
Descent Stage
Power The descent stage carried oxygen-hydrogen fuel cells for primary power; total peak power required by descent stage (when active) = 4.0 kW;
total peak power required by descent stage (when inactive) = 500 W.
Propulsion
The propulsion system had three LOX/LH2 descent engines that operated at an Isp of 459.7 sec. The engine thrust was 31.1 kN (7,000 lb). Oxygen boil-off was estimated to be at 1.2% per month and hydrogen boil-off was estimated to be at 4.3% per month. Descent delta-v: 1,900 m/s (6,233 ft/s)
Structures
The baseline primary structural material was aluminum 2024 or similar. There were two oxidizer tanks/four fuel tanks; The landing structures made up 3.3% of the total mass to be landed.
Environmental Control and Life Support System
Standard ECLSS in pressurized habitat; 13.2 m3 (466 ft3) total habitable volume; 3.3 m3 (116.5 ft3)
habitable volume per crew member; 14.2 m3 (500 ft3) Continue reading Langley Unpressurized Lunar Lander→
Team Vision 2006 Proposal
An Alternate Approach towards Achieving the New Vision
for Space Exploration
The Jupiter-III HLV is a revolutionary idea that seeks to revamp the current External Tank/SRB system of the Space Shuttle to produce a cutting-edge heavy lift launch vehicle. This proposal involves replacing the forward attachment of the External Tank with a more formidable structural system, thereby enhancing the capacity to transmit higher thrust and rotational loads. The new center tank’s upper inter-stage region would drive the attached External Tank/SRB components, reducing the stress on the aft attachment points of the LH2 tanks.
This HLV concept leverages the External Tank/SRB stack as a common core booster, providing ample room for adjustments in lift capacity through modifications to the central core lift vehicle. The parallel burn configuration of the Jupiter-III HLV offers numerous advantages, including a reduction in development costs, improved structural efficiency, and heightened payload capacity flexibility. With a large proportion of already developed components in the Shuttle External Tank/SRB system, the costs of developing this HLV would be kept to a minimum.
Moreover, the Jupiter-III HLV would optimally utilize the Kennedy Spaceflight Center’s Vehicle Assembly Building (VAB) volume, making it a more practical option than conventional stacked lift vehicle Continue reading Jupiter III Heavy Lift Launch Vehicle→
