How to: GDAL with Martian Data

I’ve seen a lot of tutorial on working with GDAL with Earth data, but not a lot for planetary data, Mars included. As I use GDAL a lot (and in need of reminder myself), why not write a how-to with Martian data.

MOLA, but in different projections (https://core2.gsfc.nasa.gov/PGDA/images/MarsTopography_GMM3.jpeg, https://astrogeology.usgs.gov/search/map/Mars/GlobalSurveyor/MOLA/Mars_MGS_MOLA_ClrShade_merge_global_463m)

Mempersiapkan Penjelajahan Ke Luar Angkasa, Dari Bumi

Untuk melakukan penjelajahan di bumi, faktor-faktor seperti arah, posisi, dan cuaca merupakan faktor yang penting saat mempersiapkan perjalanan. Dengan menggunakan sistem navigasi dan peta, serta ramalan cuaca yang akurat hingga 2 derajat per harinya[1], kita dapat mempersiapkan rute perjalanan kita untuk mendatangi lokasi yang kita inginkan di permukaan bumi, dalam kondisi perjalanan yang terbaik. Di bumi saja, kita terbiasa untuk mempersiapkan perjalanan kita, untuk melakukan penjelajahan ke luar angkasa, di tata surya kita, bahkan di alam semesta, dunia yang misterius dan jauh berbeda kondisinya dengan bumi kita, tentu jauh lebih banyak data dan persiapan yang dibutuhkan.

Planisphere

As an Indonesian, I was really not grateful (hmm, maybe not me) enough that I am able to be a viewer of the whole, both sides of the sky, able to see both Crux and Ursa Mayor, sure truly a blessing, for the whole year.

Most of these (okay, maybe no Polaris for me) (astroplot.com)

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
