SpaceX announced plans to send its first commercial mission to the planet Mars as early as 2018. In Elon Musk’s company’s plans, the journey will be carried out automatically by the Red Dragon spacecraft, a variant of the Dragon 2. The Red Dragon will be launched atop a Falcon Heavy rocket, the version of SpaceX rocket with two additional boosters. NASA will provide technical support but will not fund the mission.
The Hubble Space Telescope has identified a moon of the dwarf planet Makemake. For the moment it was simply designated S/2015 (136472) and nicknamed MK2 and it’s a small moon with an estimated diameter of about 160 kilometers (about 100 miles). The discovery came from observations made in April 2015 using the Hubble’s Wide Field Camera 3 instrument.
A few hours ago, the Sentinel-1B satellite, part of the Copernicus / GMES, was launched from the Kourou spaceport, in French Guiana, on a Soyuz-STA/Fregat-M rocket. After about 25 minutes, the satellite regularly separated from the rocket’s last stage and started sending signals. Along with it some nanosatellites of the CubeSat type and the Microscope microsatellite of the French space agency CNES were launched.
An article published in the journal “Astronomy & Astrophysics” presents maps and a catalog of compact sources obtained thanks to a project called Herschel infrared Galactic Plane Survey (Hi-GAL). The observations made during the ESA Herschel Space Telescope’s mission were used to create maps of the complete Plan Galactic in the far infrared with a level of completeness never seen before.
An article published in the journal “Nature Physics” describes an analysis of the data collected by ESA’s Venus Express space probe during the final phase of its mission. After about eight years orbiting the planet Venus, in 2014 it was sent down lower and lower into the atmosphere, where it collected many new data before ending up getting destroyed. This allowed for example to discover the extraordinarily low temperatures of some atmospheric waves that have an average of about -157° Celsius (about -250° Fahrenheit).
