In December, 2019, NASA revealed 11 successful graduates from its training program who would go on to become astronauts. The 11 people with all different skills and backgrounds are being touted to become the first people to set foot on the Red Planet, and NASA has now revealed that training is underway to get them to the International Space Station (ISS), the Moon and ultimately Mars. A select few of the space travellers will also be tasked with helping to establish a lunar colony, which NASA has said it hopes to start work on in 2024.
On a much sooner timescale, NASA said it will start launching the astronauts to the ISS this year from American soil – rather than relying on SpaceX or Russia.
NASA Administrator Jim Bridenstine said: “These individuals represent the best of America, and what an incredible time for them to join our astronaut corps.
“2020 will mark the return of launching American astronauts on American rockets from American soil, and will be an important year of progress for our Artemis program and missions to the Moon and beyond.”
Senator John Cornyn said: “For generations, the United States has been the world leader in space exploration, and Johnson Space Center will always be both the heart and home of human spaceflight activity.
“I have no doubt the newly minted astronauts will add to that history and accomplish incredible things.”
NASA revealed that following the establishment of the lunar colony in 2024, which will act as a check point for astronauts on their mission to the Red Planet, “lunar missions are planned once a year thereafter and human exploration of Mars is targeted for the mid-2030s.”
NASA explained the intense training which the astronauts had to undergo: “Astronaut candidate training for the new graduates included instruction, practice, and testing in spacewalking, robotics, International Space Station systems, T-38 jet proficiency, and Russian language.
“As astronauts, they will help develop spacecraft, support the teams currently in space and ultimately join the ranks of only about 500 people who have had the honour of going into space.
“NASA continues its work aboard the space station, which, in November, will celebrate 20 consecutive years of human occupation.”

Bright-Red "Blood Snow" Is Falling From the Sky in Antarctica – Futurism
A Facebook post by Ukraine’s Ministry of Education and Science shows a research station on an island just off the coast of Antarctica’s northernmost peninsula covered in “blood snow.”
The gory-looking scene is not the result of a seal hunt gone wrong — it’s an astonishingly red-pigmented, microscopic algae called Chlamydomonas nivalis, which thrives in freezing water as the ice melts during Antarctica’s record-breaking warm summer.
When summer hits the polar regions, the algae bloom, staining the snow and ice around it in blood-resembling red, as Live Science explains. The phenomenon was first noticed by Aristotle thousands of years ago and is often referred to as “watermelon snow” thanks to its subtly sweet scent and color.
What makes the blooming algae red is the same stuff that give carrots and watermelons their reddish tint — carotenoids.
It’s a stunning display of a natural phenomenon — but it also creates a nasty feedback loop that causes the ice to melt faster. The red color causes less sunlight to be reflected off the snow, causing it to melt faster, as the Ukrainian team explains in its post. The accelerated melting then causes more algae to grow, completing the cycle.
It’s not the only surreal display in the world caused by such a feedback loop, as Live Science points out. Blooming algae caused sea foam to swallow up the coast of a Spanish town in January. Similar algae blooms even caused shores around islands in the East China Sea to glow blue.

Scientists detect biggest explosion since Big Bang – BBC News
Scientists have detected evidence for a colossal explosion in space – five times bigger than anything observed before.
The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.
The eruption is said to have left a giant dent in the Ophiuchus galaxy cluster.
Researchers reported their findings in The Astrophysical Journal.
They had long thought there was something strange about Ophiuchus galaxy cluster, which is a giant aggregation containing thousands of individual galaxies intermingled with hot gas and dark matter. X-ray telescopes had spied a curious curved edge to it.
The speculation was that this might be the wall of a cavity that had been sculpted in its gas by emissions from a central black hole.
Black holes are famous for gorging on infalling matter, but they will also expel prodigious amounts of material and energy in the form of jets.
Scientists at first doubted their explanation however, because the cavity was so big; you could fit 15 of our own Milky Way galaxies in a row into the hole.
And that meant any black hole explosion would have to have been unimaginably prodigious.
But new telescope data from the Murchison Widefield Array (MWA) in Australia and the Giant Metrewave Radio Telescope (GMRT) in India seem to confirm it.
“In some ways, this blast is similar to how the eruption of Mount St Helens (volcano) in 1980 ripped off the top of the mountain,” said Simona Giacintucci of the Naval Research Laboratory in Washington, DC, and lead author of the study.

Astronomers have discovered the biggest explosion seen in the universe, originating from a super-massive black hole.
Scientists reported Thursday that the blast came from a black hole in a cluster of galaxies 390 million light-years away.
The explosion was so large it carved out a crater in the hot gas that could hold 15 Milky Ways, said lead author Simona Giacintucci of the Naval Research Laboratory in Washington.
It’s five times bigger than the previous record holder.
Astronomers used NASA’s Chandra X-Ray Observatory to make the discovery, along with a European space observatory and ground telescopes. They believe the explosion came from the heart of the Ophiuchus cluster of thousands of galaxies: a large galaxy at the centre contains a colossal black hole.
First hint of explosion came 4 years ago
Black holes don’t just draw matter in. They also blast out jets of material and energy.
The first hint of this giant explosion actually came in 2016. Chandra images of the Ophiuchus galaxy cluster revealed an unusual curved edge, but scientists ruled out an eruption given the amount of energy that would have been needed to carve out such a large cavity in the gas.
The two space observatories, along with radio data from telescopes in Australia and India, confirmed that the curvature was, indeed, part of a cavity.
“The radio data fit inside the X-rays like a hand in a glove,” co-author Maxim Markevitch, of NASA’s Goddard Space Flight Center in Maryland, said in a statement. “This is the clincher that tells us an eruption of unprecedented size occurred here.”
The blast is believed to be over by now: There are no signs of jets currently shooting from the black hole.
More observations are needed in other wavelengths to better understand what occurred, according to the team.
The findings appeared in the Astrophysical Journal.
