NASA: Sounds from Space

    It is said that there is no sound in the space. Instead, it is not like this. Nasa, the American space Agency, has created specific instruments to capture the “voice” of the space. In fact, here the sound exists as electromagnetic vibrations. The Plasma Wave antenna has recorded these vibrations between 20 and 20000 Hz, then they were transformed into sound for ours ears. The US Agency started to have also its own channel on Soundcloud where there is a sound archive with wonderful recordings of phenomena from the Solar System, the roar of the Shuttle departure and famous phrases said during the missions. We have selected some of the most significant tracks to create our video:

    • Radio emissions collected by the space probe Cassini, launched on October 15, 1997 with the goal of studying the planet Saturn, its ring and its moons and went into orbit on July 1, 2004;
    • the first words said by Neil Armstrong on 20th July 1969 “The Eagle has landed” to announce the moon landing of the Apollo 11’s Eagle module;
    • storms of Jupiter recorded from space probes Voyager1 and Voyager2;
    • the phrase, which is of common use today: “Houston, we’ve had a problem” that astronaut Jack Swigert used during the Apollo 13 mission to the Mission Control to report that one of the four oxygen tanks exploded and the moon landing was not possible then;
    • the sounds produced by the interstellar plasma and collected again by the Voyager probes;
    • the original audio dating back to July 21, 1969 when Neil Armstrong during the landing on the moon said: “That’s one small step for a man one giant leap for mankind”;
    • the sound of the passage of the space probe Stardust near the comet Tempel1 on 14 February 2011;
    • the countdown preceding the last launch of the Space Shuttle for mission STS-135 on 8 July 2011;
    • the sound coming from the star KIC7671081B achieved thanks to the Kepler spacecraft launched in 2009.You will find many other files within the seven playlist that NASA has shared on its Soundcloud channel if you want to try the real feeling of traveling in space.Good listening … and have a nice trip!

    PakTa: the new supersonic cargo plane

    The new vehicle that the Russians are planning is called PakTa, it is a cargo plane of the Russian army. It will fly at supersonic speeds, about 2000 kilometers per hour, and it will carry up to 200 tons. It will then be able to reach any part of the world in just seven hours carrying up to 400 tanks. The military aircraft will be equipped with a gas turbine and an electric motor that will allow a range of 7,000 kilometers. The vehicle will far surpass both in speed and load capacity the C-5 Galaxy, the largest cargo plane of the US Army, which reaches about 830 kilometers per hour with a load of 120 tons.

    The Russian program PakTa predicts that 80 new cargo planes will be built by 2024, with which the Russian army will be able to carry weapons, military vehicles and men in a very short time.

    Happy birthday Hubble Space Telescope!

    Hubble Space Telescope celebrates a quarter of century. It is in orbit by NASA April 24, 1990 to capture the wonders of the cosmos. Departed from Cape Canaveral and brought to 569 kilometers high (low earth orbit) from the shuttle Discovery, it sent by then spectacular images. It allowed us to observe natural phenomena otherwise only theorized. Weighing about 11 tons, it has a length of 13.2 meters and a diameter of 4.2 meters; it travels at the speed of 28000 km / h, using 97 minutes to complete one orbit. Powered by solar energy, captured thanks to the solar panels, and by six nickel-hydrogen batteries, Hubble sends about 120 gigabytes of data and images to the ground every week. It is characterized by a level of detail at least five times greater than the best ground-based telescopes, thanks to its primary mirror with a diameter of 2.4 meters. It is in fact extremely accurate: it is able to maintain a pointing of 7 thousandths of an arcsecond. But it was not always so. Before of that there was a drawback: the first images were distorted and blurry due to a construction defect, eliminated in 1993 by astronauts who worked directly in space. Hubble works in the visible and ultraviolet light and allows us to see more clearly the objects and phenomena that will be blurred and obscured from the earth due to the atmosphere. Only a portion of the many images collected by NASA through Hubble regards planets, stars, galaxies and asteroids.

    How we will celebrate the 25th anniversary of this giant space?

    NASA and ESA have organized scientific meetings, dissemination events and competitions. For example Hubble Mania: an online competition to vote the most beautiful image obtained with the space telescope; Ode a Hubble: a competition attended by amateur astronomers around the world by sending video dedicated to the telescope. The initiatives will continue in the coming months in order to highlight the importance not only scientific but also remembering how Hubble has transformed our idea of space.
