Everything was ready for the beginning of the return of mankind to the moon. However, during final preparations for the launch of the SLS rocket, NASA interrupted the countdown due to a fuel leak.

Flight is no longer possible, but the space agency is analyzing what happened.

Second Information at NASA, the leak occurred in the same place where the seeps appeared during the spring countdown.

Upon discovering the leak, launch controllers aborted the resupply operation, which had already been delayed by an hour due to a sea storm.

The process was slowly restarted to see if the hydrogen leak got worse, which, if it did, should end the countdown.

Artemis I: There may still be a release

The unmanned rocket launch is scheduled for today, during a two-hour "window of opportunity" that opens at 13:33 Lisbon time.

NASA has indicated that if flight is not possible today, there will be two more possible dates, September 2 and 5.

This test flight from NASA's Kennedy Space Center in Florida is designed to place a crewed capsule into orbit around the Moon for the first time in 50 years.

At 98 meters tall, the rocket is the most powerful rocket ever built by NASA, surpassing the Saturn V that put astronauts on the moon half a century ago.

The launch is intended to place the Orion capsule into lunar orbit, which instead of astronauts carries three test dummies. The lunar orbit mission is expected to last six weeks.

All this as part of a mission worth over $93 billion. But… will we see the Orion spacecraft and the SLS rocket take off to the moon today?

LINA da NASA na Lua

Special agencies, as well as private companies, played cards in the direction of studying the Moon and Mars. This time, the novelty comes from NASA, which intends to create a 3D printed lunar base.

The LINA project, which brings together NASA and AI SpaceFactory, has already shown the first versions of the lunar bases of the future of mankind on our satellite.


Abbreviation for Lunar Infrastructure Asset, a LINA is a new mission by NASA and AI Space Factory to develop an advanced 3D printed lunar base to protect astronauts when they return to the moon, to Mission of Artemis.

The US space agency has invested in getting people back to the moon, and LINA is just an attempt to expand civilization beyond Earth. That is, to have a place on the satellite that is intended for people, as well as a place that is stable and minimizes the impact of human presence.

LINA from NASA on Lua

LINA is part of REACTan abbreviation for Relevant Environment Additive Construction Technology, which aims to develop construction technologies on the lunar surface.

A full-scale architectural and structural design will be carried out taking into account lunar conditions and the needs of the Artemis mission. The scalable structure will be 3D printed under simulated lunar conditions.

NASA explains.

As LINA's design suggests, the project will meet the needs of man on the Moon, from studying the lunar topography, to a strategic deployment that will extract resources from the Sun (as well as from the satellite's permanent shadows), to the ability to expand housing units.

LINA from NASA on Lua

LINA will be a system of sliding structures that can be a single unit, as well as give rise to several, will have a living area of ​​75 sq.m., and will have an area of ​​90 sq.m. dedicated to other astronauts. The 3D-printed structure is expected to welcome astronauts to the moon over the next decade and protect astronauts from solar particles, impacts, cryogenic conditions during moonlit nights and earthquakes.

For the development of LINA, a region of the Moon was chosen, in which the Sun is almost omnipresent, which allows the generation of solar energy.

In the same way, confidential data and money are stolen. So how do you avoid becoming a victim? In this article, we will explain how to detect and avoid virus attachment in Gmail, which actually applies to any email client.

Gmail: How to Detect a Viral Attachment and Avoid It

Receive attachments daily very often. The documents, audio files and images are often attached to these emails. But not all attachments we receive are necessarily good.

Malicious attachments are those that are used to spread malware onto someone’s device. Cyber ​​attacks need vectors to spread these dangerous programs. This can be done in several ways. Dangerous investments – the most popular way.

However, when a victim downloads a malicious attachment, they are actually downloading malware onto the device. Depending on the type of malware, it can affect the machine in different ways. Some less bad, some worse. However, the consequences of downloading a malicious attachment are severe in most cases.

Signs of a Dangerous Attachment

For everything he can do, it is important to identify threats.

First, it is important to analyze the type of files

Pay attention to the content of the email

The content of the email may also indicate whether a particular attachment is malicious. For example, if you receive an email where the sender claims to have attached a document but an MP3 attachment, then you are most likely dealing with a false attachment. This is to put it mildly.

check sender

The key step is to verify the sender’s email address. An attacker cannot replicate and use a trusted source address, but will try to create very similar addresses.

For example, an attacker might slightly change the name of the company in the address (for example, “w0rten” instead of “worten”). When receiving any type of email from a new sender, be sure to take a close look at the address.
