Space-For-All at HobbySpace 18 Sep 2018, 04:59 UTC On Monday evening at the SpaceX HQ in Hawthorne, Calfornia, Elon Musk introduced billionaire entrepreneur and art collector Yusaku Maezawa, as the mystery space tourist who has reserved a BFR (Big Falcon Rocket) for a flyby trip around the Moon. (See previous posting.) The flight could happen as early as 2023.
NASA Space Station Blog 17 Sep 2018, 19:49 UTC The Expedition 56 crew members started the work week exploring a variety of life science and ensuring the upkeep of advanced space research gear. U.S. spacesuits were also being looked at today ahead of series of planned spacewalks.
astrobites 17 Sep 2018, 18:21 UTC Our story begins on a bright and not-so stormy brown dwarf. Now brown dwarfs are themselves mysterious objects, but CWW 89Ab is especially odd. But let’s start at the beginning; why are brown dwarfs mysterious? It is theorized that brown dwarfs form similarly to main-sequence stars; a gas cloud collapses, heats up, and eventually ignites. However, brown dwarfs do not have a high enough mass to start fusing hydrogen like a star and instead are left fusing deuterium. Over time, these objects cool off and start to dim and fade away.
Starts With a Bang! 17 Sep 2018, 14:01 UTC The Milky Way is our cosmic home, containing hundreds of billions of stars across 100,000 light-years. But 2.5 million light years away, our big sister, Andromeda, outclasses us in every way.
Parabolic Arc 17 Sep 2018, 07:58 UTC When astronauts land again on the surface of another world, their limited resources will allow for a short window of time each day to explore their new surroundings. Instruments designed to quickly reveal the terrain’s chemistry and form will help them understand the environments around them and how they change over time.
Spaceflight Now 17 Sep 2018, 04:19 UTC Two British-built reconnaissance satellites, one designed to test new radar imaging technology and another to collect high-resolution optical imagery, arrived in orbit Sunday after a successful liftoff aboard an Indian Polar Satellite Launch Vehicle.
Astronomy Now 16 Sep 2018, 17:47 UTC Determining where in the Milky Way a star like the sun first flared to life is a difficult challenge. Stars in the galactic disk tend to move outward over cosmic time in a phenomenon known as radial migration, which is influenced by past galactic collisions, the number of spiral arms and the size and movement of the central galactic bar.
Parabolic Arc 16 Sep 2018, 12:47 UTC A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized hazards astronauts will encounter on a continual basis into five classifications. Pooling the challenges into categories allows for an organized effort to overcome the obstacles that lay before such a mission. However, these hazards do not stand alone. They can feed off one another and exacerbate effects on the human body. These hazards are being studied using ground-based analogs, laboratories, and the International Space Station, which serves as a test bed to evaluate human performance and countermeasures required for the exploration of space.
