That wouldn’t even matter, we’ll just have to adjust out directions to the fact that North and South have flipped.

Thank you for the detailed answer, but it's not really answering my question. Your previous comment stated that

> If your phone/device is compatible with Galileo, the signal received will automatically be used for all location-based applications

but that's probably just for Galileo in general and not the new HAS, right? And so my conclusion is that no phones currently supports this new precision improvement, and we have to wait until Google adds system wide support in a future version of Android or maybe Play Services.

Although if you need detailed phase observations you have to enable that specifically in Android developer settings today, since it uses a lot more power by not switching off the receiver.

Right? Not to mention those who experienced the Great Depression, the world wars, etc. Significant life changing events are present in every generation.

NASA doesn’t fund anything. Their funds are provided by American taxpayers.

Where do people get mushrooms and other fun things?? I can barely find melatonin. /mostly rhetorical

Ah my apologies.

I falsely assumed that the regolith of impact areas would be pliable enough to serve as a heat sink, but you’re right—sand, gravel et al. are awful conductors.

Are there feasible methods for keeping lunar dust from magnetically clumping to radiators? I recall it was a concern for grounded solar arrays.

This is like when Jim decides to have one birthday party for everyone in the office.

It's easy to say that now. When you start at NASA, there's loads of employee training to do for a large number of reasons. One of these exercises that I distinctly remember was a sort of training scenario. They gave every one of us all this information, and we had to decide whether or not to greenlight the launch. Every single person in the group I was with chose to greenlight it. After that, they told us that was the exact scenario NASA leadership was in for Challenger. And we were all horrified.

"NASA is funding research these mind-blowing projects"?

So you're saying I should panic and buy toilet paper?

The Galileo High Accuracy Service (HAS) provides free of charge Precise Point Positioning (PPP) corrections, in the Galileo E6-B data component (HAS SIS) and by Internet (HAS IDD) for Galileo and GPS (single and multi-frequency) to achieve real-time improved user positioning performances.

In order to start using the Galileo HAS service, you will need a HAS-capable user equipment. Such device shall be capable of:

1. Tracking the Galileo and GPS signals supported/corrected by the HAS service. Please refer to the Galileo HAS SDD for details.
2. Receiving, decoding and applying the Galileo HAS corrections. You may receive corrections through either of the following options:

• HAS SIS. Please refer to the Galileo HAS SIS ICD for further details on reception of Galileo HAS corrections through the Galileo E6 signals (E6B data component).

• HAS Internet Data Distribution interface, based on the NTRIP protocol. The Galileo HAS Internet Data Distribution service is available under registration. Please register to the Galileo HAS Internet Data Distribution to start receiving HAS corrections through the Internet.

3. Implementing a PPP algorithm providing a Position, Velocity and Timing (PVT) solution based on the previous steps.

In section 2.4 of the Galileo HAS SDD describes the relevant assumptions at user level and the use of Galileo HAS on smartphones has not been verified. This is due to:

1. The minimum level of quality and stability required on the GNSS observables (code and phase) collected by the user receiver to support high accuracy positioning.
2. The unavailability of smartphones on the market capable to track Galileo E6 signal and implementing the Galileo HAS SIS ICD.

In case you have further doubts, please refer to our colleagues at the European GNSS Service Centre (GSC), they'll be able to provide more specific answers. You can reach them at: helpdesk@gsc-europa.eu

I was born in '77. I wanted to be an astronaut when I grew up. In second grade, we watched the Challenger launch because they were sending a teacher into space.

A few minutes later...

...I no longer wanted to be an astronaut.

The three accidents happened within a few calendar days of each other: Apollo 1 Jan 27, Challenger Jan 28, Columbia Feb 1. So I presume they chose a neutral day just before the first one for a week of remembrance.

I used to do social media work for Planetary Resources. Had their kickstarter cube sat not been destroyed during the Antares launch in 2014 I'd still be working with them and they would like have been launching this year for testing

I see zero reason to use darkest anything for heatsinks. You don't have (external) convection on the Moon, so you have a) radiation, b) direct heat transfer. Radiation doesn't care, just protect radiators from the incoming radiation. Just rotating radiators 90 to the sunlight direction into the sky is enough. Direct transfer would satiate stone around it pretty quickly even if it was in the dark for million of years. If you go under the surface with some kind of pipes, it again doesn't matter, if it's in a crater or on a moon plain on a moon noon.

SpaceX has no interest in building anything other than transportation and information architecture. Musk has spoken about how the company won't operate any bases on Mars or the moon, but will be happy to sell rides. ... And they have done just that by selling two rides to this company AstroForge for their asteroid mining development and exploration missions.

Musk talks a lot though. If Gwen Shotwell starts talking about SpaceX developing any new products or mission profiles, you can have much more confidence in it. She sticks to the "SpaceX is a transportation company" line.

It's got to be related. I'm very much not any kind of expert; but the Magnetosphere is generated by the motion of the liquid iron core, the North Pole is determined by the geometry of that motion relative to the surface, and we are measuring these processes in tandem. There may be a black-box of complex math between these two things, but I feel like it's certain they are related.

There is a small memorial to Kalpana Chawla at the University of Texas at Arlington, where she got her Master's degree. It's in Nedderman Hall on the first floor behind a little wall. It's free to visit and open to the public, although you will have to pay for parking.

You mean the book "The Apollo Murders"? Where the crew of Apollo 18 have to land on the moon and stop the Russians from getting a rock.

Gus got a raw deal. His Mercury capsule sank and everyone blamed him for the failure. Then he gets the Apollo 1 seat and burns to death in a fire.

Thanks for the explanation.

Would be helpful if they add “research” between funding and these.
