NASA may fly crew into deep space sooner, but there’s a price

NASA will likely launch its first astronauts into deep space since the Apollo program on a less powerful version of its Space Launch System rocket than originally planned. Although it has not been officially announced, in recent weeks mission planners at the space agency have begun designing “Exploration Mission 2” to be launched on the Block 1 version of the SLS rocket, which has the capability to lift 70 tons to low Earth orbit.

On Thursday, during a Congressional hearing, the agency’s acting administrator, Robert Lightfoot, confirmed that NASA is seriously considering launching humans to the Moon on the Block 1 SLS. “We’ll change the mission profile if we fly humans and we use the Interim Cryogenic Propulsion Stage (ICPS), because we can’t do what we could do if we have the Exploration Upper Stage,” Lightfoot said.

The key difference between the original configuration of the SLS rocket’which NASA has spent more than $10 billion developing since 2011’and its successor is the upper stage that sits atop the booster. Under current plans, the weaker upper stage, known as the’ICPS, was to fly only once’on the maiden flight of the SLS rocket in 2020. Then, NASA was to switch to a new, much more powerful second stage that would increase the SLS rocket’s overall performance by about 50 percent.

Now, NASA will probably fly the SLS rocket in its Block 1 configuration at least two or even three times before it debuts the more powerful variant of the booster. By doing so, it may get humans into deep space faster. The current launch date of 2023 for the deep space Exploration Mission 2 could move forward, a NASA spokeswoman confirmed. “The earliest possible launch date is being assessed, with a formal decision expected in the coming months,” she added.Even with a Block 1 SLS, NASA should be able to fly this mission profile for Exploration Mission 2 but without the nine-ton payload.

However, this decision also suggests the agency remains far from developing the powerful Exploration Upper Stage, which NASA says it needs to carry out an ambitious program of lunar exploration. This may well delay meaningful exploration in and near the Moon’into the mid- and late-2020s, at the earliest.

Quite a lot has been going on:

Go On A 4K Joyride Around The Moon, Courtesy of NASA

Well today, NASA’s got a little something to wet our whistle. Its’Lunar Reconnaissance Orbiter (LRO) mission has been closely examining the Moon’s surface since June 2009, and has been beaming fascinating footage of our only natural satellite back to Earth since then.

And now, using the Orbiter’s treasure trove of detailed footage, NASA has recreated a five-minute’ “Tour of the Moon” animation from 2011 in glorious 4K, including perspectives that can only be seen from space.

NASA shoots human sperm into space

With the new experiment, NASA wants to research how human sperm cells react to microgravity and whether humans could procreate in space.

The International Space Station's crew will test the sperm samples to see if conception can happen in zero gravity. Buzz60

Space agencies and companies have sent many a strange object into space: pizza,’lego mini figures’and even a’convertible.’All have made their way into the seemingly endless world of microgravity that lies just beyond our planet.

But a new experiment takes the cake: for research project Micro-11, NASA’is now sending frozen samples of human sperm to space.

“As we plan to travel beyond the space station with thoughts of colonization on the moon and Mars and other heavenly bodies, the question of whether or not multi-generational survival can occur ‘ not only in animals but in humans ‘ is a very fundamental question that needs to be addressed,” said Joseph Tash, a researcher at the University of Kansas Medical Center who will examine the sperm upon its return to Earth.
