3-D Print Your Planet (and Space-Related Objects)

Writing this as it’s still fresh in mind (looking at a lot of drafts sitting in my notebook) as well as for the next print if any. I can and will update this, but for now, it’s publishable in my standard.

I have just obtained an opportunity to do an outreach. It’s a very interesting event, and as I previously have obtained a 3-D print of Gale Crater, I was very interested to create a print of my area of research (still Mars, but more to the south)



The print in question. As blurry as it can get  Anyone can guess what this is?

Accessibility and accommodation in events (and media), and a lot of ramblings related to that

This is a part of an ever-updating post, but the first part is alright so I upload it

Upload your 2015 General Assembly presentation

EGU’s PICO (flash-talk) illustration. See the lower screen on the right-hand side? It is allocated for wheel-chair users. EGU also provides a quiet/ prayer room, which I also appreciate. Please no alcohol-only poster session, then I will give five stars. Credit: Stephanie McClellan/EGU)

As a person with an overall privileged condition: healthy body, no allergy (anymore), have my own saving so I can pay something upfront first then being reimbursed, as well having a  laidback and nrima (Javanese, lit: accepting, which sometime’s not a good characteristic to have) personality, although I tried to give my suggestion in accessibility and accommodation whenever I can, especially in regards to other people or participants in an event I’m an organiser of, I’ve never really given a thought about this enough about when I’m the one being accommodated for.

After meeting a lot more people in a wider spectrum and having more knowledge and discussions about accessibility and being asked on what kind of accessibility access and accommodation I or people like “me” actually want, I did some hard contemplation and some more reading (read: tabs in high tens). I will give some of my thought and experiences below.

(Making a note for a friend who’s in charge of accessibility and accommodations, hence a few of my notes for her sprinkled around)

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 (,

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.

Bukan persiapan seperti ini (

How to: Scientific Presentation

I… prefer doing oral presentation more than doing poster one. Other than it seems like a bigger prestige, printing and hauling posters especially in international flight is such a pain.

This is definitely longer than 56 cm! Source: Amazon
