Opportunity Rover’s first and last images from the Martian surface

The first and the last images of NASA’s Opportunity rover from the Martian surface. The first photo (on the left) was acquired on Sol 1 (at approximately 14:58:27 Mars local solar time on January 25, 2004). The last photo (on the right) was taken on Sol 5111 (on June 10, 2018 ), before the rover entered hibernation due to a huge dust storm.

Terraforming Mars [here’s why it’s so hard]

If we want to colonize Mars in the future, it would be better for us to terraform the planet, in order to make the colonization process safer and sustainable. But, terraforming Mars will be a real challenge for humanity.

InSight Lander Takes a Selfie on Mars

NASA’s InSight lander takes a selfie – this is what it looks like on Mars (InSight is the abbreviation for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport). With its solar panels deployed, InSight is about the size of a small bus.

Speed of Light [perfect visual explanations]

The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

SpaceX Starhopper, Starship and Super Heavy Booster 3D Models Comparison

Finnish 3D artist Kimi Talvitie has made some really impressive 3D models of SpaceX’s stainless steel Starhopper (the shorter test vehicle of Starship), Starship (previously known as the BFS – Big Fragging Spaceship) and Super Heavy booster (previously known as the BFR – Big Fragging Rocket) and published them on his Twitter account. They are amazing!

InSight Mission Raw Images are available on the web

NASA’s InSight Mars Lander (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport – InSight) was launched on 5 May 2018 at 11:05 UTC aboard an Atlas V-401 rocket. It traveled 483 million kilometers (300 million miles) in almost six months and successfully landed at Elysium Planitia on Mars on 26 November 2018 at 19:52:59 UTC. Shortly after landing, it has sent back the first photo. Now, NASA publishes InSight Mission raw images on its website, you can see them any time you want on the mission’s multimedia webpage.

Earth, a “Bright Evening Star” as seen from Mars

On January 31, 2014, about 80 minutes after sunset on its 529th Martian day (or sol), NASA’s Curiosity Rover has turned its camera back home and took this amazing photo of Earth and Moon from a distance of around 99 million miles (160 million kilometers). In the image which has the serial number PIA17936, Earth can be seen as the brightest point of light in the night sky, a little left of the center of the photo, and our Moon appears just below Earth.

How NASA Reinvented The Wheel

On August 6, 2012, at 05:17 UTC, NASA has successfully landed a Mini-Cooper-sized rover, Curiosity, on Aeolis Palus in Gale Crater on Mars. The 900-kg rover (899 kg, to be exact, which is 1,982 lbs) is equipped with six 50 cm (20 in) diameter wheels in a rocker-bogie suspension (see notes 1). For the first time in the history of space exploration, the suspension system also served as landing gear for the vehicle, unlike its smaller predecessors.

Curiosity “soft-landed”  (wheels down) on the surface of Mars. But, even it’s called “soft-landing”, the touchdown speed was 0.6739m/s vertical and 0.044m/s horizontal, which could damage the wheels. Plus, while the rover is moving, the wheels should withstand the substantial damage through the rough Martian surface. That’s why the wheels of the Curiosity rover have been one of the biggest technical difficulties encountered on the mission (see notes 2).
