Continuing our series on the historical interaction between Western astronomy and Indigenous communities, this post discusses ALMA and other observatories in Chile.

We can evolve bacteria, plants and animals. Is it ethical to evolve the human body? I say yes.
And it becomes a moral imperative because it’s going to be really hard to live on Mars if we don’t fundamentally modify the human body. Right? You go from one cell, mom and dad coming together to make one cell, in a cascade to 10 trillion cells. We don’t know, if you change the gravity substantially, if the same thing will happen to create your body. We do know that if you expose our bodies as they currently are to a lot of radiation, we will die. So as you’re thinking of that, you have to really redesign things just to get to Mars. Forget about the moons of Neptune or Jupiter.
And to borrow from Nikolai Kardashev, let’s think about life in a series of scales. So Life One civilization is a civilization that begins to alter his or her looks. And we’ve been doing that for thousands of years. You’ve got tummy tucks and you’ve got this and you’ve got that. You alter your looks, and I’m told that not all of those alterations take place for medical reasons.
Seems odd.
A Life Two civilization is a different civilization. A Life Two civilization alters fundamental aspects of the body. So you put human growth hormone in, the person grows taller, or you put x in and the person gets fatter or loses metabolism or does a whole series of things, but you’re altering the functions in a fundamental way.
Update: JAXA and Mitsubishi Heavy Industries have postponed today’s launch of the HTV-8 cargo ship due to a fire near the mission’s H-IIB rocket’s launchpad.
An unpiloted Japanese supply ship will launch to the International Space Station today (Sept. 10) and you can watch it leave Earth live courtesy of NASA and the Japan Aerospace Exploration Agency (JAXA).
The robotic spacecraft HTV-8 (also known as Kounotori8) will launch toward the space station from the Tanegashima Space Center in southern Japan at 5:33 p.m. EDT (2133 GMT). It will be 6:33 a.m. local time Wednesday at the launch site. You can watch the launch live here and on Space.com’s homepage via NASA TV at 5 p.m. EDT (2100 GMT). JAXA is offering its own webcast here beginning at 5:07 p.m. EDT (2107 GMT).

An international team of astronomers has detected a new high-mass gamma-ray binary (HMGB) in the Milky Way galaxy. The newly found HMGB, designated 4FGL J1405.1–6119, is one of only a handful of such objects discovered to date. The discovery was announced in a paper published August 28 on the arXiv pre-print repository.
HMGBs consist of an OB star in orbit with a compact object. In these systems, interactions between the two objects result in an emission with spectral energy distribution (SED) peaks above 1.0 MeV. They are assumed to be precursors to high-mass X-ray binaries (HMXBs).
HMGBs are very rare objects. Astronomers estimate that there are about 100 still undetected HMGBs residing in our home galaxy. Moreover, many known gamma-ray sources of as-yet unknown nature, could potentially be high-mass gamma-ray binaries.
PD Aerospace is developing a PD engine that can be used both in the atmosphere and in space. They plan to reach an altitude of 100 kilometers in 2020. https://www8.cao.go.jp/space/policy/suborbi/dai1/siryou2-2.pdf
Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.
Discovering the length of a day on any planet seems like a straightforward task: Find some feature on the planet and clock it as it rotates around once. Or, if it’s a gas giant like Jupiter, which has no solid surface features, scientists can listen for periodic modulations in the intensity of radio signals created within the planet’s rotating magnetic field.
And then there is Saturn, which for decades has defied attempts to pin down out its exact rotation period. Now a new study in AGU’s Journal of Geophysical Research: Space Physics may have finally unveiled the gas giant’s trick for hiding its rotation, and provide the key to giving up its secret.
China plans to launch an artificial moon to light up the night skies and save electricity. What would be the consequences?
A Japanese cargo spacecraft loaded with more than four tons of supplies, spare parts and experiment hardware is scheduled to launch from the Tanegashima Space Center in southern Japan to the International Space Station at 5:33 p.m. EDT Tuesday, Sept. 10 (6:33 a.m. Sept. 11 in Japan). Live coverage of the launch and capture will air on NASA Television and the agency’s website.
The Japan Aerospace Exploration Agency (JAXA) unpiloted H-II Transport Vehicle-8 (HTV-8) will launch on a Japanese H-IIB rocket on the tenth anniversary of the first HTV cargo spacecraft launch. Live coverage will begin at 5 p.m.
The spacecraft will arrive at the station Saturday, Sept. 14. Live coverage of the spacecraft rendezvous and capture will begin at 5:30 a.m. Expedition 60 Flight Engineer Christina Koch of NASA, backed up by her NASA crewmate Andrew Morgan, will operate the station’s Canadarm2 robotic arm from the station’s cupola to capture the 12-ton spacecraft as it approaches from below. Robotics flight controllers will then take over the operation of the arm to install HTV-8 to the Earth-facing port of the Harmony module where it will spend a month attached. Flight Engineer Luca Parmitano of ESA (European Space Agency) will monitor HTV-8 systems during its approach to the station.
