    Asteroid Impact Mission (Spanish)

    La misión AIM (Asteroid Impact Mission), candidata a ser desarrollada, actualmente en fase de diseño preliminar.

    AIM se lanzaría en octubre de 2020 y su objetivo es viajar al sistema binario de asteroides Dídimos para estudiar la luna Didymoon. El sistema Didimos cuenta con un cuerpo principal de unos 800 metros de diámetro y una luna que orbita alrededor de este cuerpo principal, de unos 170 metros de diámetro aproximadamente, está luna se la conoce con el nombre de Didymoon. El sistema Didimos se aproximará a 11 millones de kilómetros de la tierra en 2022.

    AIM escaneará la pequeña Didymoon en detalle con su cámara VIS, con imágenes térmicas y un radar de alta resolución para construir mapas detallados de su superficie y estructura interior.

    La nave principal de AIM llevará al menos tres sondas más pequeñas – el módulo de aterrizaje, Mascot-2, desarrollado por el Centro Aeroespacial Alemán (Mascot-1 ya está volando en la misión Hayabusa-2 de JAXA), así como dos o más CubeSats. Así, AIM pondría a prueba las comunicaciones ópticas y los enlaces inter-satelitales en el espacio profundo, una tecnología que será esencial para la exploración futura del espacio.

    Si se aprueba, AIM también será la contribución europea a la misión AIDA, Asteroid Impact and Deflection Assessment. En 2022, la sonda DART (Double-Asteroid Redirection Test), parte dirigida por la NASA, llegará al sistema binario y se estrellará contra Didymoon a una velocidad de unos 6 km/s.

    El impacto será observado por AIM y por sus CubeSats. A través de las imágenes de alta resolución de AIM se evaluará el tamaño y la profundidad del cráter tras el impacto. AIM realizará una segunda fase de mediciones para comparar detalladamente la estructura del objeto, así como su órbita al rededor del asteroide mayor, antes y después del impacto.

    NASA Administrator Charles Bolden on Commercial Space

    NASA is on a Journey to Mars and commercial space is a key component of our strategy to send American astronauts to the Red Planet in the 2030s.
    In 2010 when President Obama laid out his vision for space exploration, it may have been hard to believe that six years later we’d be regularly transporting cargo to the International Space Station on commercial spacecraft, or that we’d be on the verge of returning launches of American astronauts to the Station from U.S. soil on the spacecraft built by American companies.
    Today, that’s our reality.
    SpaceX and Orbital ATK are the first commercial space companies to deliver cargo to the ISS.
    We’ve also ordered the first missions from SpaceX and The Boeing Company — the first American companies that will carry American astronauts to space. The first astronauts are now training for test flights aboard commercial spacecraft in preparation for those missions.
    We are closer than ever before to sending American astronauts to Mars. We’re “insourcing” American jobs and empowering American entrepreneurs and innovators to expand the new commercial market in low-earth orbit.
    Today, we’re marking another significant milestone. We are announcing the companies that will continue our successful commercial cargo program until at least 2024. This phase of the program will allow us to continue using the Space Station as our springboard to the rest of the solar system and a test bed for human health in space.
    Our investment in commercial space is creating jobs and it’s bringing us closer to sending American astronauts to Mars. With the commercial cargo successes to date and our announcement today – I am very confident that commercial space will continue to propel our nation into the future – we’ll continue to Launch America.

  • Inside LISA Pathfinder, with narration

    Inside LISA Pathfinder, with narration

    ESA’s LISA Pathfinder mission is a technology demonstrator that will pave the way for future spaceborne gravitational-wave observatories. It will operate about 1.5 million km from Earth towards the Sun, orbiting the first Sun–Earth ‘Lagrangian point’, L1.

    The animation of the spacecraft build-up begins with two freely falling test masses. Between them lies the central component of LISA Pathfinder’s payload: the 20 x 20 cm optical bench interferometer. A set of 22 mirrors and beam-splitters directs laser beams across the bench. There are two beams: one reflects off the two free-falling test masses while the other is confined to the bench. By comparing the length of the different paths covered by the beams, it is possible to monitor changes accurately in distance and orientation between the two test masses.

    A box surrounds the two masses without touching them, shielding them from outside influence and constantly applying tiny adjustments to its position. This internal payload is housed in a central cylinder, isolating the test masses from the other components of the science payload and spacecraft.

    The solar array provides power to the instrumentation and acts as a thermal shield. Microthrusters control the spacecraft to keep the master test mass centred in its housing, opposing the force of the solar radiation pressure – the main source of ‘noise’ – impinging on the solar array.

    Although LISA Pathfinder is not aimed at the detection of gravitational waves themselves, it will prove the innovative technologies needed to do so. It will demonstrate that the two independent masses can be monitored as they free-fall through space, reducing external and internal disturbances to the point where the relative test mass positions would be more stable than the expected change caused by a passing gravitational wave, equal to much less than the size of an atom.

    LISA Pathfinder – Window on the gravitational universe

    LISA Pathfinder’s name, Laser Interferometer Space Antenna, clearly indicates the role of precursor that this mission plays. Its goal is to validate the technology required to detect gravitational waves from space. Gravitational waves will open a new door in our understanding of the Universe, and at the same time help to verify Einstein’s General Theory of Relativity. LISA Pathfinder will be launched early December 2015 on a Vega rocket from Kourou in French Guiana.

    This timelapse shows ESA astronaut Andreas Mogensen working with Roscosmos cosmonaut Sergei Volkov during the iriss mission to unpack, setup, test and then store the MARES muscle-measurement machine in Europe’s space laboratory Columbus on the International Space Station over three days.

    The Muscle Atrophy Research and Exercise System, or MARES for short, is a three-in-one muscle-measurement machine on the International Space Station that monitors astronauts’ muscles as they work out.

    Muscle strength decreases during spaceflight and researchers need to know why this happens in order to prepare for long-duration missions and safe space tourism. MARES is an exercise bench that offers detailed information about how muscles behave during spaceflight.

    MARES was a large part of Andreas’s ten-day iriss mission to the International Space Station that started 2 September 2015.

  • Lisa Pathfinder mission overview

    Lisa Pathfinder mission overview

    LISA Pathfinder will pave the way for future missions by testing in flight the very concept of gravitational wave detection: it will put two test masses in a near-perfect gravitational free-fall and control and measure their motion with unprecedented accuracy. LISA Pathfinder will use the latest technology to minimise the extra forces on the test masses, and to take measurements.

    The inertial sensors, the laser metrology system, the drag-free control system and an ultra-precise micro-propulsion system make this a highly unusual mission.

    LISA Pathfinder is an ESA mission, which will also carry a NASA payload.
