SpaceIL's Crashed Spacecraft Spilled Tardigrades on the Moon – Nosy Media

The Arch Mission Basis despatched its first archive to house in 2018 in the glove compartment of Elon Musk’s Tesla, which is now in a 30-million-year orbit round the solar. That archive comprises Isaac Asimov’s Basis trilogy, which is inscribed in a quartz disk utilizing an experimental 5D optical expertise developed by physicists at the College of Southampton.

However that storage medium has limitations. Digital applied sciences and encoding requirements are nice for compressing numerous data right into a small quantity of house, however they’re additionally short-lived—how many individuals are you aware who might play a VHS tape at present? If you wish to create a library for people 1000’s or hundreds of thousands of years in the future, your finest wager is to maintain it analog.

However analog storage takes up a number of room. So sending the bulk of human information to house would require so much of compression. To do that, Spivack tapped Bruce Ha, a scientist who developed a method for engraving high-resolution, nano-scale pictures into nickel. Ha makes use of lasers to etch a picture into glass after which deposits nickel, atom by atom, in a layer on prime. The pictures in the ensuing nickel movie look holographic and may be seen utilizing a microscope able to 1000x magnification—a expertise that has been out there for a whole bunch of years.

The lunar library on the Beresheet lander consisted of 25 layers of nickel, every only some microns thick. The primary 4 layers comprise roughly 30,000 high-resolution pictures of e-book pages, which embrace language primers, textbooks, and keys to decoding the different 21 layers. These layers maintain almost all of the English Wikipedia, 1000’s of traditional books, and even the secrets and techniques to David Copperfield’s magic tips.

The lunar library contains 1000’s of high-resolution pictures of e-book pages compressed into just some sq. inches.

Spivack had deliberate to ship DNA samples to the moon in future variations of the lunar library, not on this mission. However a number of weeks earlier than Spivack needed to ship the lunar library to the Israelis, nonetheless, he determined to incorporate some DNA in the payload anyway.


Ha and an engineer on Spivack’s staff added a skinny layer of epoxy resin between every layer of nickel, an artificial equal of the fossilized tree resin that preserves historic bugs. Into the resin they tucked hair follicles and blood samples from Spivack and 24 others that he says signify a various genetic cross-section of human ancestry, along with some dehydrated tardigrades and samples from main holy websites, like the Bodhi tree in India. A number of thousand additional dehydrated tardigrades had been sprinkled onto the tape used to safe the lunar library to the Beresheet lander.

The promising factor about the tardigrades, says Spivack, is that they might hypothetically be revived in the future. Tardigrades are identified to enter dormant states through which all metabolic processes cease and the water of their cells is changed by a protein that successfully turns the cells into glass. Scientists have revived tardigrades which have spent as much as ten years on this dehydrated state, though in some instances they can survive for much longer with out water. Though the lunar library is designed to final for hundreds of thousands of years, scientists are simply starting to know how tardigrades handle to outlive in so many unforgiving environments. It’s conceivable that as we study extra about tardigrades, we’ll uncover methods to rehydrate them after for much longer durations of dormancy.


Spivack says that including the DNA-filled resin to the lunar library at the final minute was a serious threat, as a result of any errors in the way it was integrated might have ruined the nickel engravings. Looking back, nonetheless, it could have been what saved the library from destruction. The resin layers added a major quantity of power to the lunar library, which made it much less prone to break aside upon affect. Furthermore, Spivack says that the warmth generated by the affect wasn’t excessive sufficient to soften the nickel layers, which had been themselves encased in a number of protecting layers to dam radiation. “Paradoxically, our payload could also be the solely surviving factor from that mission,” Spivack says.

A giant full beaver moon set to dazzle Metro Vancouver skies – Vancouver Courier

Published

on

By


While it is getting darker earlier in Metro Vancouver, this month’s full beaver moon promises to illuminate the night sky.

The November full moon is thought to have derived its funny name because it occurred during the optimal time to trap the furry creatures. In fact, both colonial Americans as well as the Algonquin tribes referred to it as such.

article continues below

“Why this name? Back then, this was the month to set beaver traps before the swamps froze, to ensure a supply of warm winter furs,” reports Farmer’s Almanac.

While it is commonly known as the beaver moon, it was also called the Full Frost Moon by other North American Tribes.

According to the Old Farmer’s Almanac, the moon will be fullest during the day on Tuesday, Nov. 12. However, Vancouver stargazers will still be able to see the nearly-full moon in all her celestial glory the night before (Nov. 11) as well as later that night (Nov. 12).

What’s more, this full moon casts long, hauntingly beautiful shadows in the Northern Hemisphere. They are similar to those cast by the midday summer sun, as the moon is extremely high in the sky during this time.

Stargazers should opt to travel as far away from city lights as possible in order to avoid light pollution that will obscure the clarity of heavenly bodies. While this works best the in more remote places, anywhere that has a higher elevation will also provide more ideal viewing conditions.

All-female space walk a starry-eyed achievement: The Statesman – The Straits Times

Published

By


NEW DELHI (THE STATESMAN/ASIA NEWS NETWORK) – It is a starry-eyed achievement almost literally.

Christina Koch and Jessica Meir, two NASA astronauts, have crafted space history by embarking on what they call the first all-female space walk.

Tasked with replacing a failed power control unit, their performance has been decidedly spectacular as they floated feet-first out of the International Space Station’s (ISS) Quest airlock on Friday (Oct 18).

The spacewalk, known as an extra-vehicular activity (EVA) in the jargon of astronauts, took place seven months after the originally scheduled date for an “all-female outing”, which had to be dropped because the ISS had only one medium-sized spacesuit on board.

The agency sent up a second medium spacesuit in October.

From space to ground zero, the happiest thought at the moment must be that both the achievement and empowerment of women are now manifest in the rarified atmosphere of space.

Very appropriately has the significance of the spacewalk been summed up by Christina: “I think it’s important because of the historical nature of what we’re doing,” she said ahead of the spacewalk.

“In the past, women haven’t always been at the table. It’s wonderful to be contributing to the space programme at a time when all contributions are being accepted, when everyone has a role. That can lead in turn to increased chance for success.”

On closer reflection, more than the space-walk, it is the assignment that is historic to fix a failed power control unit.

Previously, 14 women and 213 men had carried out spacewalks. The first woman was the Russian cosmonaut Svetlana Savitskaya, who went outside the USSR’s Salyut 7 space station in 1984.

Video footage from the astronauts’ helmet cameras, as they dangled 260 miles above Earth, provided a live stream of the painstaking operation to carry the new hardware, install it and then return the faulty battery to the airlock for a postmortem back on Earth into why it failed.

Their work in space will, therefore, be followed up by the labs on Earth.

Exceptional must be the projected coordination between space science and pure science as the world knows it.

At 40, Christina is due to remain on the ISS until February, bringing her total time in space to 328 days, the longest single spaceflight by a woman and just short of Scott Kelly’s 340-day record.

Researchers are collecting extensive biomedical data on the impact of spaceflight on her system.

The majority of data available is on male astronauts, but there is some evidence that there are sex differences in response to a space environment.

One study found that women are more likely than men to suffer faintness as a result of “orthostatic hypotension”, a cardiovascular issue.

Men appear more prone to vision changes caused by spaceflight associated neuroocular syndrome (Sans).

A flight to space has a lot to bear on human health. The contretemps notwithstanding, NASA has reached a milestone.

By



WASHINGTON, Oct. 22, 2019 /PRNewswire/ — Media accreditation is open for the launch of the next SpaceX delivery of science investigations, supplies, and equipment to the International Space Station.

A SpaceX Dragon cargo spacecraft is scheduled to launch on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida no earlier than Wednesday, Dec. 4 at 12:48 p.m. EST.

Media prelaunch and launch activities will take place at NASA’s Kennedy Space Center and neighboring CCAFS. Credentialing deadlines are as follows:

  • International media without U.S. citizenship must apply by 4:30 p.m. EDT Sunday, Oct. 27.
  • U.S. media must apply by 4:30 p.m. EST Friday, Nov. 15.

All media accreditation requests should be submitted online at:

https://media.ksc.nasa.gov

For questions about accreditation, please email ksc-media-accreditat@mail.nasa.gov. For other questions, contact Kennedy’s newsroom at 321-867-2468.

Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, physical sciences, Earth and space science. Advances in these areas will help to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars. Space station research through the ISS National Lab also provides opportunities for other U.S. government agencies, private industry, and academic and research institutions, to conduct microgravity research that leads to new technologies, medical treatments, and products that improve life on Earth.

Highlights of space station research that will be facilitated by research aboard this SpaceX Dragon mission include testing the effectiveness of a device to separate and capture water droplets suspended in an air stream, delivering a next-generation spaceborne system to image Earth in higher spectral resolution than currently possible onboard the TERRA satellite, and testing conditions to develop an inexpensive and scalable process to manufacture optical materials in space.

Cargo resupply from U.S. companies ensures a national capability to deliver critical science research to the space station, significantly increasing NASA’s ability to conduct new investigations at the only laboratory in space. This is the 19th SpaceX mission under NASA’s Commercial Resupply Services contract.

The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and enables research not possible on Earth. The space station has been occupied continuously since November 2000. In that time, 239 people and a variety of international and commercial spacecraft have visited the orbiting laboratory. The space station remains the springboard to NASA’s next great leap in exploration, including future missions to the Moon and eventually to Mars.
