Scientists grow plants in lunar soil samples

Will it be possible to grow plants on the moon?

So far, they have been grown in lunar soil samples at the University of Florida.

Even for scientists, this was a surprise, says Robert Ferl, a scientist at the Institute of Food and Agricultural Sciences at the University of Florida.

“The first message was: “How wonderful! Plants can grow on lunar soil. In addition, we have now learned that there are some things that we must know and be able to do better if we want to cultivate.”

The experiment was conducted by scientists from the Institute of Food and Agricultural Sciences at the University of Florida.on lunar soil brought to Earth by Neil Armstrong and his team during the Apollo 11 mission more than 50 years ago.

Biologist and geneticist Anna-Lisa Paul explains: “During the first week of life, there really was no difference between the control and lunar plants. All we need to do is figure out how to mitigate the negative effects.”

**A year ago. Several mini-capsules of watercress seeds were placed in a gram of lunar soil.** Although the researchers found that the shoots grew more slowly and with stunted roots, the results were considered encouraging.

Geologist Steven Elardo says: “This was the first step in what we hope will be a very long, decades-long process of discovering this material, and when we get back to the Moon, we will do it on the lunar surface.

The ability to grow food on the moon will be a giant step forward for future astronaut missions. The study is relevant to NASA, which is preparing for manned and robotic exploration of the moon as part of the missions under the Artemis program.

“This investigation is critical to NASA’s long-term human exploration goals,” said Bill Nelson, head of the US space agency. “We will have to use the resources found on the Moon and Mars to develop food sources for future astronauts who will live in deep space.”

For your experience, The researchers used just 12 grams of lunar soil (or a few teaspoons) collected from various locations on the Moon during the Apollo missions..

In small thimble-sized pots, about a gram of soil—regolith—was placed at a time, water was added, and then seeds. Nutrient solution was also added daily.

In the same time, the seeds were planted in the soil of our own Earth and samples of the lunar and Martian soil for comparison.

After two days, the seeds of the lunar samples germinated.

“All plants in both the lunar soil samples and the controls looked the same on day six,” said Anna-Lisa Pohl, lead author of the study.

But after that, it turned out that lunar plants grow more slowly and have stunted roots.

After 20 days, scientists collected them and studied the DNA. They found that plants on the Moon reacted the same way they would in a hostile environment, such as soil with too much salt or heavy metals.

In the future, scientists want to understand how this environment can be made more welcoming.

These are the first experiments to study whether plants can grow on lunar soil and the subsequent 11-year effort to obtain the rare material. Because soil is so valuable, NASA only loaned 12 grams of soil to the testers.

Scientists have long wondered if the moon could host a harvest, but now that space agencies are planning to bring humans back to the surface and possibly building lunar settlements for visitors, the question has become more pressing.

Kerbal Space Program 2 now kicks off in early 2023

Kerbal Space Program 2 now kicks off in early 2023

The Kerbal 2 space program will remain on earth for some time to come. Developer Star Theory has delayed the release of the game until early 2023.

Creative director Nate Simpson explained on the project’s forums and in a video message that development of the space flight simulator has “enormous technological complexity” and the team needs more time to bring it to perfection. In the video posted below, Simpson clarifies by saying:

“We have also set very high quality standards. the game should [perform] for a wide range of vehicles. Graphics must be second to none. The universe should be rich and interesting to explore. We set ourselves an internal goal – to create an original and breathtaking experience.

Like its well-received predecessor, Kerbal Space Program 2 challenges players to manage a space program run by cute green astronauts to build rockets and other spacecraft for space exploration. The game uses realistic physics to allow players to perform realistic orbital maneuvers used to locate and land on celestial bodies. The sequel was first announced at Gamescom 2019 with a release window in 2020. Unfortunately, the COVID-19 pandemic delayed development and forced the team to aim for Fall 2021 to arrive later this year.

Kerbal Space Program 2 is aimed at PC at launch, with console versions coming later in the year.

Unfortunately, Kerbal isn’t the only major game that has been pushed back to 2023. We recently compiled a list of all the best games of 2022 to avoid this year, which you can read here.

See photos of the Blood Moon during the morning lunar eclipse - Science

Another lunar eclipse occurred this morning, resulting in the formation of a red moon and the formation of a supermoon, a phenomenon also known as the “moonflower”. It only partially obscures the Sun. This phenomenon has been observed in America, Europe and other regions of the globe. .

The phenomenon reached its peak around 4:11 am, when the Moon was completely in the cone of the Earth’s shadow. The total eclipse ended at 4:54 am. The moon came out of the shadow at 5:55, but the penumbra remained for another hour.

See images of the lunar eclipse in the gallery:

“Although completely in shadow, the Moon is still visible, but has a reddish and brownish color. In fact, during a lunar eclipse, the sun’s rays fall on the moon after crossing the Earth’s atmosphere, where they scatter and lose a large amount of blue and green light, ”the Lisbon Astronomical Observatory explained. During an eclipse, the moon was illuminated not with white, but with a reddish light. The moment of the Full Moon phase lasted only two minutes.

At 7:52 AM, the Moon completely emerged from the penumbra, returning to its usual hue, although it was already below the horizon.

According to the observatory, the next total lunar eclipse will occur on November 8, 2022.

Introduced in iOS A few years ago, the widget feature is now a new category of apps that have been captivating the youth in recent months and becoming a favorite for photo-sharing. These are services such as Locket and LiveIn that display contact photos on the home screen of a mobile phone.

New sharing apps have become Gen Z’s way of interacting online. Locket and LiveIn apps are not exclusive iPhone and also available for Android system. However, they have become popular among iOS device users, especially in the United States.

In general, these applications work quite simply. To send a picture, simply open the app, take a picture, and choose who to share it with. To view files sent by your friends, simply activate the widget on the home screen of your mobile device. In this way, you can follow updates from friends without having to view unwanted posts such as advertisements and other posts.

“It’s more or less what you do in Snapchat, but without having to open the app,” explained Jimmy Wells, a LiveIn user based in the US, according to a posting on technologist Olhar Digital’s website. These apps only became possible in 2020 when the widget feature was included in the Apple operating system. But this functionality has been around for over a decade on Android.
