Why NASA sent human sperm to space?

Previously several species, including frogs, salamanders, sea urchins, jellyfish, snails, medaka fish, nematode and other aquatic invertebrate animals, have successfully undergone breeding in space

With talk of space tourism and even trips to Mars, NASA has launched human sperm to the International Space Station (ISS) to test what happens when it gets exposed to zero-gravity environment.

The mission, dubbed Micro-11, technically began on April 1, when NASA sent frozen human and bull sperm on board a Falcon 9 rocket to the ISS, the Inverse reported late on Thursday. The astronauts aboard the ISS will thaw and chemically activate the samples to prepare them for union with an egg. Using video recording they will track the sperm movements and send them back to Earth for further analysis.

“Based on previous experiments, it seems the lack of gravity facilitates sperm mobility,” Fathi Karouia, lead scientist for NASA’s space biology project, was quoted as saying to Inverse.

“This is in line with other investigations on different model organisms which have shown that microgravity conditions trigger faster cell regeneration. “This flight project is the first to apply proven analytical methods to assess the fertility of human and bovine sperm in spaceflight,” Karouia said.

The experiment could also offer new insights into the ways long-duration spaceflight will influence human reproduction. Though this is not the first time sperm has been sent into space for testing, it could offer new insights into the ways long-duration spaceflight will influence human reproduction.

“This research is looking at early fundamental microgravity science,” the report said. Previously several species, including frogs, salamanders, sea urchins, jellyfish, snails, medaka fish, nematode (roundworm, known as Caenorhabditis elegans), and other aquatic invertebrate animals, have successfully undergone breeding in space. Moroever, aquatic invertebrates like amphipods, gastropods (pond snails), ostracods and daphnia (water flea) produced their offspring or repeated their life-cycles under microgravity during four months in space, the report said.

USA, Shutdown

The partial shutdown of the US federal government has had a serious impact on the country’s space agency NASA and development work on most future space missions has been slowed or suspended.

However, NASA has not been totally grounded by the partial government shutdown that began on December 22, after last-minute negotiations in Congress failed to end a budget standoff.

Over 95 per cent of the space agency’s employees have been furloughed. As a result, various research projects, including the Hubble Space Telescope has been put on hold, the Space.com reported on Wednesday.

Hubble suffered a mechanical problem that only furloughed NASA employees could repair.

Many workers also gathered outside the Johnson Space Center in Houston to protest the shutdown and its deleterious effects on their lives and the nation’s space programmes.

The Telescope facilities that have so far remained open during the shutdown will soon run out of money and cease operations.

This includes the National Radio Astronomy Observatory (NRAO), a federally funded organization that operates the Atacama Large Millimeter Array (ALMA), the Green Bank Telescope and the Very Large Array (VLA), the report noted.

The partial shutdown become the longest on record after January 12, overtaking the previous record of the 21-day impasse in 1995-96 under then President Bill Clinton.

US shutdown delays space missions but NASA not grounded: Report,

President Donald Trump and the Congress have been at loggerheads over his demand to include in the budget $5.7 billion funding for building a border wall along the Mexico border. Democratic leaders have rejected his call.

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA), also called the “flying telescope” has also ceased operations since the shutdown.

The telescope, which is mounted to the fuselage of a Boeing 747 aircraft, has not flown since the shutdown began, the report said.

However, despite the shutdown some “excepted” employees remained at work, assisting astronauts aboard the International Space Station (ISS) and other space missions, the report said.

Last week, astronauts aboard the ISS conducted a range of scientific experiments and public-outreach work. They engaged in an orbital Q&A with school kids and answered a variety of questions, from the nature of the research performed aboard the ISS to the type of training astronauts receive to whether your ears pop in space.

On January 13, a SpaceX Dragon cargo capsule departed the orbiting lab for Earth, eventually splashing down in the Pacific Ocean. The robotic Dragon brought down important scientific research and hardware for examination here on terra firma.
