A new study from Boston University’s Center for Space Physics has determined that wind is an effective option for power generation on Mars! This is especially important to combat times of low solar activity such as we are seeing with the current dust storm, and to balance power needs when a piece of equipment may be in a limited sunlight environment for half the year. Additionally, radioisotope power (ie. nuclear) as powers the Curiosity rover would be counter-indicated in a polar region as it would impact any science experiments being conducted.
The original experiments for this paper were conducted in 2010. At the time it was determined that wind was a possible power source given climate conditions on the Red Planet, however there were concerns over the required size of the turbines given the state of technology at the time. Now with 8 more years of materials science and research behind us, the equipment that could be deployed for this purpose has sufficiently improved that it truly can be seen as a viable option. Another great step forward for Mars!

When the starting whistle of the universe blew, and our solar system began to coalesce, it now turns out that Mars was running laps around the Earth in terms of planet formation. This is important because it means the planet would have had more than a 100-million-year head start over Earth regarding the development of a viable habitat. The report in the June 27th issue of Nature states that only 20 million years after the dust and gas around our sun had started to form the planets, Mars was up and running!
While these discoveries about the early crust formation on Mars may suggest a longer timeframe for possible development of life, it also indicates a relatively thin atmosphere which is a disappointing side note to this work. I suppose none of that will be terribly important once we start terraforming the place, and restoring it to the former glory of a green and blue world!
SpaceX is once again getting ready to resupply the ISS, as part of their ongoing contract with NASA to provide that vital service. The launch is scheduled for 5:41am Eastern on June 29th, from pad SLC-40 at Cape Canaveral. The hardware for this mission will include both a previously flown Falcon booster as well as a previously flown Dragon capsule.
It’s exciting that the development of the Crew Dragon is moving ahead strongly, and every launch of the existing resupply dragon capsule provides more data and more assurance that the systems are up to the challenge of safely launching and returning astronauts. What a relief it will be soon, to have that capacity within our own control after many years of outsourcing.
As construction of the BFR is underway at the Port of LA, we are all trying to imagine just how Big this Falcon Rocket is really going to be. Well, some enterprising soul put together a captivating video that helps us to comprehend the size, and it must be accurate enough for Musk to re-tweet. So – in case you haven’t seen it, have a look at how big this Falcon Rocket really is!
Owing to the major differences between ostensibly similar planets of Earth and Mars, the red planet is now experiencing a massive dust storm the size of North America. Right in the midst of this maelstrom is the little Opportunity rover, hunkered down as best as it can against the fury of the bringer of war.
What is truly amazing, however, is that the rover is expected to weather the storm with little difficulty, only experiencing a brief suspension of it’s ongoing mission objectives.
The large concerns in a situation like this, of course, are that the solar panels may become covered with too much dust to properly funciton, or that the sun is obscured for too long causing a sharp decline in temperature of the rover. Neither eventuality is expected to slow down the scrappy piece of tech, and NASA appears to be in good shape to claim yet another of the ongoing victories in their rover program.
Well Gazetteers, it’s last minute, but here’s an update that all of us night owls will (probably) get to see the next Falcon 9 launch at 12:45am Eastern, from Cape Canaveral. This mission is to establish the new SES communication satellite in orbit, providing a high level of broadband availability to Asian-Pacific and Middle East regions.
Unfortunately, as reported previously, this is a Block 4 booster, so recovery will not be attempted with this launch. Pretty soon, everything will be Block 5 and we can count on a smooth touchdown on the droneship or mainland pad every time.
Here at the Mars Gazette, we are fans of Lego – as are most sentient beings. It is therefore with great delight that we direct your attention to the Lego Ideas line (sets driven by ideas from the fan community) which is currently voting on a tremendous SpaceX set! It comes not only with a Falcon 9, a Falcon heavy and a Dragon Capsule, but also a Roadster and mini-Starman.
Bop on over to the Lego site and cast your free, no obligation vote of support for this set. If they hit 10,000 then there’s a good chance they will produce it!
