Perseid, with Nice Maps

I don’t know why, seems like my writings lately are mostly about maps? I wonder… Anyway, tonight and yesterday night were the peak of Perseid Meteor Shower this year (mostly yesterday, but today should be quite fine). As I live far from civilisation the city this year, the result of the quick sighting I’d done last night was quite nice. Though I didn’t venture far from the flat, I could see a lot of shooting stars (basically the shower part) coming from the east (where Perseid was located these time of the year before the dawn), and I believe there’s a fireball too!


With this infographic, I have benefits of not needing to write about the meteor shower and not needing to write a lot as this article seemed long enough already

National/ International Astronomy Olympiad Problem Sheets

[Updated: 10 February 2019]

I have some of the files, but I think it’d be easier to link to their pages as well (so that if anyone asks me I can just link him/ her this). Basically, you can just go to their own respective websites, but having them in one place helps a lot (especially for my Indonesian students/ friends). I try to link to official websites if I can. If I don’t have the links but I have the files, will upload them.

Designing Mission Patches

As I was looking for outreach activity to do, I encounter designing space mission badges/ patches. Space mission badges is usually designed to be worn on an astronauts’ suit. They usually have the austronauts’ names, the space shuttle, symbol/ logo about the mission, and flags of the country/ies involved.

These are from all the Space Transportation System (STS) a. k. a.  Space Shuttle  missions

Specks of Indonesia in the Solar System

(This is a part of Martian Series (Planet series?) I’m queueing in this moment)

Looking through this map which I have previously mentioned in this article, a crater’s name lit up my interest. Tomini Crater? Is that the same Tomini with the Tomini I know? After shifting through Martian Crater name list, I found 4 of craters with Indonesia-related names. Apparently this has been caught interest of other Indonesian article writers as proven by these articles. Are there other features in out solar system with names based on Indonesian culture and mythology? Apparently they are. Shifting through IAU Gazetteer of Planetary Nomenclature, there are few familiar an unfamiliar names with “Indonesian” in their description.

Unrelated but let me put this picture of Pratiwi Sudarmono (Whoa there’s a Hanacaraka writing of her name in her Wikipedia entry)

Martian Maps, Maps, Maps

(This is a part of Martian Series I’m queueing in this moment)

So, compared to Earth, which is mapped often already, and the Moon, which has been fully mapped using NASA”s Lunar Reconnaisance Orbiter, Mars hasn’t been mapped as often. The highest resolution global topographic map of Mars until now is produced using MOLA data (Mars Orbiter Laser Altimeter), which, although pretty precise in altitude, only has the resolution of about 463 m/ pixel. But! Based on MOLA data alone, there are a lot of interesting Mars maps in different style being produced. Basically this post was born because of me stumbled upon this vintage-style Mars map created by Eleanor Lutz a.k.a. Tabletop Whale. I knew that there are a lot of interesting (data-wise and style-wise) maps on Mars, so I will share a few I can think of.
