Like the Mercury and Apollo capsules, like the space shuttles, the ISS, to borrow a phrase, belongs in a museum.
A Stellar Post
The Parker solar probe, which perhaps we could call the opposite of New Horizons, will attempt to explore some of those mysteries, most significantly the origin of the solar wind.
Fourteen Exciting Engineering Projects
Each of these projects receives $175,000.00 in grants for phase one work - you can read more about the program here, where you will also find links to detailed descriptions of each of the projects.
Energy Storage
If I wanted to make this post extremely short, I could probably leave it at this: we humans are absolutely terrible at energy storage.
Moon to Mars Public Comment Opportunity
There is a public comment period open from now until May 31st for NASA's defined objectives in the Moon to Mars program, which can all be found here: Moon to Mars Objectives. NASA has some details about the public comment period here: NASA Seeks Input. To make comments, go here: Feedback on the draft.
Solar Flares and Aquatic Suction Cups
I couldn't decide between two articles this week, so I decided to just post two. First up, a research paper I came across in Science Advances that studies how suction cups adhere underwater.
Conservation and Cycles
In any closed system, quantities must be conserved. Thermodynamics inform us that energy is conserved. Linear and angular momentum are both conserved, whether we’re looking at billiard balls in a Newtonian paradigm, or photons in a quantum system. Special relativity expands conservation even further to the equivalence between matter and energy. In a closed system, where nothing can escape, quantities are inevitably conserved.
The James Webb Space Telescope – A Christmas Present
This has been decades in the making, and I have been watching the observatory be delayed again, and again, and again for years now, so it was remarkable when it finally launched.
TESS: Transiting Exoplanet Survey Satellite
As a bit of a side project at work recently, I did some modeling work on TESS, which is a NASA spacecraft that was launched to help search for exoplanets using the transit method (I know, you could never have guessed that from the name's acronym breakdown). Working with satellites as much as I do, this was a really interesting project, because it was quite distinctive in its orbit and mission architecture from most spacecraft that I get to study on a regular basis. For one thing, it is a remarkably low-cost, robust, straightforward system, quite different from what you often see with NASA programs, which because of their scientific goals are often pushing the very edge of our capabilities and therefore become very complex and very expensive. For another, it utilizes a simply fascinating orbit. Since I've been trying to post occasional in-depth articles on various academic topics, it seemed appropriate to share some of what I learned from that project here.
Lunar Regolith: Update
A few weeks back, we posted about how NASA was planning to contract with commercial entities to obtain material from the lunar surface, known as lunar regolith. I came across an article on NASA's website this morning (which may or may not be my internet browser's homepage) that announced they had made selections for that exact mission.
