Re: Finding hidden planets

It is refreshing mind, stuck within discussions the spectacular missions, discoveries and theories (still all of them 'academic'), promising to find new. This shows how much we don't know or don't have enough observations of the universe. Great one to remind where we are with current knowledge, at w...

Re: Sutherland satellite launch site legal challenge

Here is an interesting article, which tells us about all aspects of the light pollution from satellites. A bit long read, but I found it worth it. https://www.science.org/content/article/satellite-swarms-are-threatening-night-sky-creating-new-zone-environmental-conflict?utm_campaign=news_daily_2021-...

Re: Mercury flyby images received

We’ve really missed seeing the planet. And of course, with new data coming to us from: 1. ESA probe’s map of the surface and gravitational field for study inner structure investigations. 2. JAXA probe’s data on magnetic field and its interaction with the solar wind. The Mercury fly-by is special as ...

Re: Sutherland satellite launch site legal challenge

There is a lot of data available publicly for the satellites observations, being contributed with amateur ones as well, like SatNOGS, and for sure many satellite observation communities. Starlink is in the spotlight due to the scale of the mission for the one leading company. And it had issued the s...

Re: Hycean planets

Careful and effective data combining together with cooperation show that it is possible to get more data with the facilities that we already have functioning. Good example demonstrated by scientists is WASP-127b ('a hot Saturn' that orbits a Sun-like star located about 525 light-years away). Combine...

Re: Earth’s own auroras

If a planet has an atmosphere and magnetic field, they probably have auroras. This reading has a comprehensive information on the Earth's aurora. https://www.space.com/15139-northern-lights-auroras-earth-facts-sdcmp.html It was really of quite mystical phenomenon over centuries. And up till now it h...

Re: Sutherland satellite launch site legal challenge

SpaceX is not alone in pushing to launch large numbers of internet satellites (though it is the largest one with announcing 2.5% of failures, which is quite a big number for 14,000), climate surveillance satellites have planned intense missions as well. Only part of the satellite constellations is l...

Avoiding the reentries controlled [or not controlled] should be a top issue.
Wherever it falls or burns, it is pollutant to the ecosystems.

Re: Could Mars One Ever Work?

The spaceship was not sleeping for 50 years. Today engineering is mature, tested with numerous designs and flights. So that we can plan realistic and bald missions, including sending numerous facilities in short timelines without unnecessary too much of reinsurance and redundancy. The management of ...

Re: Sutherland satellite launch site legal challenge

Multistage rocket launches were one of the issues for selecting rocket launch sites till about 1990’s passivation implemented. Though nowadays multistage rocket parts are recommended (UN, ITU) to be moved to a disposal orbit, they can either burn in the atmosphere or become space debris. Moreover, e...

Re: Sutherland satellite launch site legal challenge

That is a good point. Though nowadays a multistage rocket parts either burn in the atmosphere or become space debris, exclusions still exist (which we can find in latest news).

Re: Chinese astronauts return to Earth

Good news.
The more effective and mature capability for the space exploration within the leaders of the field, the better for the space exploration goals of the humanity. Of course in a way of cooperation.
