CREWS'PREPARATION FOR THE ISS

NASA and Private Space Companies elaborated a Crew Transportation System (CTS) to orbital destinations based on a Design Reference Missions (DRMs) framework. 

For the CTS to provide successful services to the ISS, 2 major objectives must be met. The first one is to insure a crew rotation capability for 4NASA or NASA-sponsored crew-members. LEARN MORE

SPACE HABITAT: WHERE, HOW AND WHAT KIND?

The Cislunar space, is the place to support Asteroid Mission Concepts, for the assembly of Mars Transit Vehicles, for Orbital Habitats, as well as support service for international and/or commercial interests. Learn More

INTERNATIONAL SPACE STATION (ISS) - HABITAT CONCEPT

The United States Orbital Segment consists of pressurized habitable modules that are approximately 4.5 m in diameter with varying lengths between 5 and 11 meters. The sizes of these modules were dictated by the cargo bay size and lift capability of the Space Shuttle. Learn More

SPACE LAUNCH SYSTEM - HABITAT CONCEPT

The Skylab was a large single module habitat that provided about 555 m3 of habitable volume for about 49 metric tons (mt). This is similar to many modules on the ISS where ten times the mass at 450 mt resulted in less habitable volume at 355 m3. Learn More

THE LUNAR ORBITAL PLATFORM, "GATEWAY", OR LOP-G

As reflected in the NASA's Exploration Campaign, the next step in the human spaceflight is the establishment of U.S. pre-eminence in the cislunar space through the operations and the deployment of a U.S.-led Lunar Orbital Platform, “Gateway,” (LOP-G).

The Gateway will be constructed in orbit, incrementally, with the uses of the American-built Orion spacecraft and the Space Launch System (SLS), as well as commercial launch vehicles.

In fact, NASA plans to build the Gateway with just five or six rocket launches, compared to the 34 launches it took to build the space station. Large parts will be set up by automatic assembly, mean robotically. LEARN MORE

CHANG'E-4'S MISSION TO THE MOON WILL BE HISTORICAL!

For the first time a country will land a spacecraft on the far side of the Moon! Chang'e-4 will be the fourth mission in its series named after the Chinese moon goddess.

In October of 1959, the Luna 3 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan. Luna 3 was the third spacecraft to reach the Moon and the first to send back pictures of the Moon's far side. The pictures were noisy and indistinct, but because the Moon always presents the same face to the Earth, they offered views of a part of the Moon never seen before.

The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age. Published: September 26, 2017. Credit: NASA

The two-part missions of Chang'e-4 will focusing on the low-frequency astronomy and the investigation of the subsurface, the topography and the mineralogical composition of the lunar far side. Learn More

WHAT WE KNOW ABOUT TITAN

With its 5150-km diameter, Titan is the largest moon of Saturn and the 2nd-largest planetary satellite in Milky Way after Ganymede (5276 km). But, it is the only natural satellite known to have a dense atmosphere with clear evidence of stable bodies of surface liquid. Its atmosphere is largely nitrogen with clouds of methane and ethane. The climate is dominated by seasonal weather patterns as on Earth with its rain and wind, which creates some dunes, rivers, lakes, seas and deltas. Learn More

The FY 2019 budget request includes $10.5 billion to pursue an exploration campaign that will focus on transitioning LEO operations to commercial providers and returning humans to the Moon and cislunar space, with eventual missions to Mars and beyond. NASA will evolve its core capabilities through continued technical advancements and new approaches and industrial partnerships to maintain the U.S.’s leadership role in human spaceflight. 

The campaign will be enabled by pursuing near-term milestones for lunar exploration, such as the commercial launch of the power propulsion element, a key element of the Lunar Orbital Platform-Gateway. A new Lunar Discovery and Exploration program would support innovative approaches to achieve human and science exploration goals by funding contracts for commercial transportation services and the development of small rovers and instrument to meet lunar science and exploration needs.

The Space Launch System (SLS)

The first launch of the NASA Space Launch System (SLS) is scheduled for 2018, with a capability of over 70 t or 154,000 lbm of payload to Low Earth Orbit (LEO). Not only its payload is greater than the twice of the Space Shuttle, the SLS will be the first in over 40 years that will have the capability to go well beyond LEO.

In parallel with the development of the SLS, NASA work on two other exploration systems, that is the Orion Program and the Ground Systems Development and Operations (GSDO)Program. The Orion spacecraft is designed to carry astronauts on exploration missions into Deep Space, means for long travel. The GSDO Program is converting the facilities at NASA’s Kennedy Space Center (KSC) into a next-generation spaceport capable of supporting launches by differents vehicles. LEARN MORE
