Photo Credit: Blue Origin Blue Origin’s effort to send tourists to the edge of space moved one step closer Wednesday, when its previously-flown NS4 New Shepard launch vehicle roared aloft from Launch Site One in West Texas, kicking off this particular booster’s second flight of the year. It also marked ...

Using nuclear devices to deflect or disrupt an asteroid. Sounds a bit crazy, no? Maybe a little too Hollywood? And yet, detonating nukes in space may be necessary someday for the sake of planetary defense. In order for this method to be effective, scientists need to work out all the particulars in advance. That means knowing how much force will ...

Whenever I wipe the dust off my coffee table or catch a glimpse of dust motes floating in sunlight, my spacey mind always wonders, is any of that cosmic dust? It just might be. But the amount of space dust that lands on our planet every year might surprise you. Scientists have long known that there is annual flux of ...

(13 April 2012 – Iridium) Iridium Communications today announced that the Republic of Indonesia’s government has adopted Iridium Push-to-Talk (PTT) devices to support communication efforts across the country. By fully deploying 500 Iridium PTT handsets, the Indonesian government now has a reliable “grab-and-go” real-time satellite communications solution, ideal for communications on-the-move applications across the country’s diverse island landscapes.

The two ...

Ever since it landed in the Jezero Crater on Feb. 18th, 2021, the Perseverance rover has been prepping its scientific instruments to begin searching for signs of past life on the Red Planet. These include spectrometers that will scan Martian rocks for organics and minerals that form in the presence of water and a caching system that will store samples ...

We tend to image planets as spheres. Held together by gravity, the material of a planet compresses and shifts until gravity and pressure reach a balance point known as hydrostatic equilibrium. Hydrostatic equilibrium is one of the defining characteristics of a planet. If a planet were stationary and of uniform density, then at equilibrium, it would be a perfect sphere. ...
