The pandemic forces NASA to delay a new launch | Digital Trends Spanish

The coronavirus pandemic forced NASA to delay the launch of the Landsat satellite that was scheduled for September 16. The liftoff was to be carried out at the Space Launch Complex 3 at the space forces base in California, and corresponds to a joint effort by NASA and the United States Geological Survey (USGS). The launch has been rescheduled for September 23. According to what the space agency itself indicates, this delay is due to the shortage of oxygen, a critical component of rocket fuel. This shortage is worldwide because liquid oxygen is used in hospitals to care for the most serious COVID-19 patients. POT."The demand for liquid oxygen caused by the pandemic has affected the supply of this component that comes from the Defense logistics network and its supplier, Airgas," NASA said...

United States close to unveiling a secret space weapon | Digital Trends Spanish

According to a post by Breaking defense, The United States could be close to publicly demonstrating the capabilities of a new, until now, secret space weapon. According to the article, the top military commanders have been debating for more than a year whether to reveal this weapon, which would have been developed as part of a Special Access Program, which is reserved for highly classified information. The Donald Trump administration considered revealing the space weapon at the annual Space Symposium in 2020, which ended up being canceled due to the coronavirus pandemic. The original idea was to show the technology as a validation of the Space Force and the Space Command, which is responsible for military operations in outer space. Military officials also considered unveiling the weapon...

Japan’s ambitious plan to reach a moon of Mars | Digital Trends Spanish

Japan also wants to become a relevant player in the space race. The Asian nation has just revealed its ambitious plans with which it could even get ahead of the United States and China. Japan's Aerospace Exploration Agency (JAXA) has mentioned that the country wants to reach Phobos, one of the natural satellites of Mars, with the intention of collecting samples and bringing them to Earth. The mission could be carried out in 2024 to bring the samples in 2029; in this way it would be ahead of the other two powers. JAXA wants to launch an MXX, or Martian Moons eXploration, at Phobos, which is 9,000 kilometers from Mars. The idea is to be able to collect 10 grams of Martian soil that could help to understand the evolution of the Martian biosphere. The Japanese space agency estimates that...

SpaceX Launches Satellite for US Space Forces | Digital Trends Spanish

SpaceX has successfully announced the launch of a GPS satellite for the United States Space Forces, which had been powered by Donald Trump during the first years of his tenure. It should be remembered that the announcement of this force was harshly criticized for the excessive economic expense that it would mean in addition to the fact that the United States does not even have its own ship to transport the astronauts. Compared to today's launch, this satellite will provide better navigation capabilities to the United States, as well as better technology to protect against interference. For its launch, the space exploration company used a first-stage Falcon 9, which could be successfully recovered by a controlled landing on its unmanned spacecraft in the Atlantic. At the same time, ...

Protests against SpaceX over Turkish satellite launch | Digital Trends Spanish

SpaceX's good present seems overshadowed by a massive protest by hundreds of people in Hawthorne, California, where the company's headquarters are located. According to a report by CBS Los Angeles, a hundred protesters, mostly Armenians residing in the United States, protested demanding that Elon Musk's company cancel the launch of the Turkish Turksat 5A satellite, scheduled for November 30. Armenian residents claim that this communications satellite will be used to carry cargo that can be used for war crimes, specifically for the inhabitants of Armenia. This occurs in the context of the armed conflict between Armenia and Turkey, which has intensified in recent times, claiming hundreds of fatalities in the last month alone. Fred Tatlyan, organizer of the protest, assured that he i...

Some exoplanets may be watching us | Digital Trends Spanish

It is possible that our planet is currently being observed from billions of kilometers away. Is it a disturbing idea? A group of astronomers has pointed out that some exoplanets, that is to say planets beyond our Solar System, have a direct line of sight to observe the biological properties of the Earth from very far away. Astronomers from the Carl Sagan Institute of Cornell and Lehigh University have identified 1,004 stars similar to our Sun that could contain Earth-like planets that would be able to detect the chemical traces of life on our planet. The article was already published in the Monthly Bulletin of the Royal Astronomical Society and is titled "What Stars Can See Earth as a Transiting Exoplanet?" "Let's reverse the point of view of other stars and ask from what point of...

They record the volcanic impact of a moon of Jupiter | Digital Trends Spanish

Images obtained by the Atacama Large Millimeter / submillimeter Array (ALMA) show for the first time the effect of volcanic activity on the atmosphere of Jupiter's moon Io. With 400 active volcanoes that expel sulfur gases, Io is the most volcanically active moon in our Solar System. Precisely, these gases stain it yellow, white, orange and red when they freeze on its surface. The atmosphere of Io can give us important information about the volcanic activity of this unique satellite, as well as its interior and everything that happens under its crust. In order to distinguish the processes that give rise to Io's atmosphere, a group of astronomers used ALMA to obtain images of the satellite as it passed inside and outside of Jupiter's shadow. "As it passes through Jupiter's shadow an...

Pentagon accuses China of stockpiling anti-satellite weapons | Digital Trends Spanish

A report released by the Pentagon this September 1, it directly accuses China of accumulating weapons for the attack of satellites orbiting the Earth, with strategic-military purposes. Since 2000, the Department of Defense presented this investigation and here it is argued that China already has operational ground missiles that can reach satellites in low orbit and "probably intends to search for additional ASAT weapons capable of destroying satellites up to geosynchronous Earth orbit." One of the things that most concern the United States is the dominance of space that the Asian giant may be exercising through the implementation of this weaponry. "China for years has continued to strengthen its military space capabilities despite its public stance against the militari...

OGO 1: a satellite that was turned into scrap and exploded | Digital Trends Spanish

It was on September 4, 1964 that NASA launched the OGO 1 satellite from Cape Canaveral, designed to study the Earth's magnetosphere and its interaction with the Sun-Earth space weather environment. This object, which eventually turned into scrap, weighed 487 kilograms and made one of the first orbital observations of a comet, observing 2P / Encke in the ultraviolet in 1970. OGO 1 was placed on standby in 1969 and was formally deactivated in 1971, thus it had been inactive for 49 years. This Saturday, August 29, therefore, 56 years of space life were ended for the NASA satellite, since it returned to the Earth's atmosphere in Tahiti and completely disintegrated. The American meteorologist Bill Gray, one of the first to predict hurricanes in the world, was one of those w...
