SpaceX Crew Rocket Ready For Launch In January: NASA

The Jan. 7 launch date announcement comes a day after NASA said it would conduct a "cultural assessment study" of the companies.

The first flight of a SpaceX rocket tailored to fly astronauts to the International Space Station is set for liftoff from Kennedy Space Center in Florida on January 7, NASA said on Wednesday.

The launch test is a crucial milestone in the space agency’s Commercial Crew Program, which aims to launch humans to space from U.S. soil for the first time in nearly a decade.

The U.S. National Aeronautics and Space Administration said SpaceX’s Crew Dragon spacecraft — which will shuttle three astronauts to space from the same launch pad that sent Apollo 11’s three-man crew to the moon in 1969 — will make its debut flight atop SpaceX’s Falcon 9 rocket on January 7.

While NASA did not detail the flight path, it said the test would provide data on the performance of the Falcon 9, Crew Dragon capsule, and ground systems, as well as on-orbit, docking and landing operations.

SpaceX and Boeing Co are the two main contractors selected under NASA’s Commercial Crew Program to send astronauts to space as soon as 2019, using their Crew Dragon and CST-100 Starliner spacecraft respectively.

Since the U.S. space shuttle program was shut down in 2011, NASA has had to rely on Russia to fly astronauts to the space station, a $100 billion orbital research laboratory that flies about 250 miles (402 km) above Earth.

The Demo-1 launch is the latest test in a rigorous certification timeline imposed under NASA’s Commercial Crew Program. While SpaceX is targeting early January, NASA spokeswoman Marie Lewis said the demo mission could be pushed back because “flying safely has always taken precedence over schedule.”

Founded by Tesla Inc Chief Executive Elon Musk, SpaceX said if the January 7 test is successful, it plans to launch its first crewed mission in June 2019, but the timeline may shift.

Boeing plans a similar test launch of the Starliner spacecraft atop its Atlas 5 rocket as soon as March, with a crewed mission following in August.

NASA’S Twins Study Claims, Long-term Spaceflight Not Linked to Major Health Risks

"It's almost as if the body's on high alert," said Christopher Mason, Associate Professor at Weill Cornell Medicine.

While it was previously thought that long duration spaceflight can affect the human body, even at the molecular level, new results from NASAs “Twins Study” has showed that there are no major warning signs and no reason to think humans cannot survive a two-and-a-half-year round-trip journey to Mars.

As part of the “Twins Study”, NASA astronaut Scott Kelly spent a year in space while Mark, his identical twin, stayed on Earth as a control subject to look at the effects of space travel on the human body.

These comparisons, however, has not raised any red flags about long-term spaceflight on the International Space Station (ISS), NASA officials were quoted as saying at the annual meeting of the American Association for the Advancement of Science here.

“It’s almost as if the body’s on high alert,” said Christopher Mason, Associate Professor at Weill Cornell Medicine.

The space sojourn also changed the activity of some of his genes.

“It’s mostly really good news,” Mason said, adding, “the body has extraordinary plasticity and adaptation to being in zero gravity, at least for a year”.

According to Craig Kundrot, Director of NASA’s space life and physical sciences division, so far the space agency’s research found nothing that would make a Mars mission impossible.

According to report, the biggest concern is radiation as such a mission would expose astronauts to levels of radiation greater than permitted under current guidelines. That would not necessarily prevent a mission, but it remains a concern.

However, Kundrot cautioned that the twin study has only two people as samples. “We don’t regard any of this as conclusive, but on the whole it’s encouraging,” he said, adding, “there are no new major warning signs”. (IANS)
