NASA Developing Technology For Human Missions to Moon, Mars

NASA said its series of crewed missions to Mars, planned to start in the 2030's and culminating in a surface landing, would be supported by the work it does on the Moon in the coming years

Revealing its human explorations plans, NASA has told the US Congress that the agency is currently focusing on developing technologies and systems that enable a series of human and robotic lunar missions that are extensible to Mars.

The “National Space Exploration Campaign” that NASA submitted to the Congress on September 24 calls for human and robotic exploration missions to expand the frontiers of human experience and scientific discovery of the natural phenomena of Earth, other worlds and the cosmos, the US space agency said in a statement on Thursday.

The campaign has five strategic goals, including returning US astronauts to the surface of the Moon to demonstrating the capabilities required for human missions to Mars and other destinations.

NASA said it intends to transition from the current model of human space activities in low-Earth orbit to a model where the government is only one customer for commercial services.

The US space agency is building a plan for Americans to orbit the Moon starting in 2023, and land astronauts on the surface no later than the late 2020s.

A key component of establishing the first permanent American presence and infrastructure on and around the Moon is the Gateway, a lunar orbiting platform to host astronauts farther from Earth than ever before, NASA said.

Some elements of the Gateway already are under construction at NASA centers across the United States, including facilities in Ohio, Texas and Alabama, and at commercial partner facilities.

The Gateway will be assembled in space, incrementally, using the Orion spacecraft and SLS, as well as commercial launch vehicles. The first element, providing power and propulsion, will launch from Florida in 2022, NASA added in the statement.

“The lunar surface will serve as a crucial training ground and technology demonstration test site where we will prepare for future human missions to Mars and other destinations,” NASA said, adding that by the late 2020s, a lunar lander capable of transporting crews and cargo will begin trips to the surface of the Moon.

NASA Planning Asteroid Impact Exercise Next Week

NASA’s PDCO and other US agencies and space science institutions, along with international partners, will participate in the exercise

Aimed at effective disaster management, NASA and its international partners are planning to participate in an exercise that will play out a realistic — but fictional — scenario of an asteroid on an impact trajectory with Earth.

The scenario begins with the fictional premise that on March 26, astronomers “discovered” a NEO they consider potentially hazardous to Earth.

After a “few months” of tracking, observers predict that this near-Earth object (NEO) – dubbed 2019 PDC – poses a 1 in 100 chance of impact with Earth in 2027 (in real life, the international community has decided that a 1 in 100 chance of impact is the threshold for action).

Participants in this exercise will discuss potential preparations for asteroid reconnaissance and deflection missions and planning for mitigation of a potential impact’s effects, NASA said.

Scientists believe that these exercises can help people in the planetary defence community to understand what those on the disaster management side need to know.

“This exercise will help us develop more effective communications with each other and with our governments,” Lindley Johnson, NASA’s Planetary Defence Officer, said in a statement on Wednesday.

Better communication of the hazards posed by NEOs such as asteroids or comets has been a top priority for international groups, such as NASA’s Planetary Defense Coordination Office (PDCO), the European Space Agency’s Space Situational Awareness-NEO Segment and the International Asteroid Warning Network (IAWN).

Developed by the NASA Jet Propulsion Laboratory’s Center for NEO Studies (CNEOS), the asteroid impact exercise next week is scheduled to take place at the 2019 Planetary Defense Conference to be held in the US from April 29 to May 3.

NASA’s PDCO and other US agencies and space science institutions, along with international partners, will participate in the exercise, the US space agency said.

Next week’s exercise events will occur over the five days of the conference, with exercise leaders briefing participants on the status of the scenario at the end of each day and soliciting response ideas and feedback, based on the latest fictional data, NASA said. (IANS)
